    专利说明:

    The production relates to a climate sensor device for measuring one or more indoor climate indicators, such as room temperature, relative humidity and / or carbon dioxide concentration, or outdoor climate indicators such as wind strength or rainfall intensity.
    A climate sensor device used to measure climate indicators is known in the art. The measured data is used centrally to control indoor climate control systems such as heating, cooling or ventilation systems including mechanical and natural ventilation control. The data is sent to a central control unit which controls the indoor climate of the room or zone, where the central control unit also controls the climate of one or more other rooms or zones, and thus also receives data from other sensor devices.
    The known sensor device comprises one or more climate sensors which continuously measure climate indicators, and a microprocessor processing unit which processes incoming data, as well as a memory for storing device settings and / or measurement data. The sensor device is mounted on a wall with climate sensors located within the device and / or climate sensors located in one or more positions in the given room or zone. The sensors send measurement data to the processor unit of the sensor device.
    The sensor device also includes a wireless data transmitter which transmits measurement data to the centrally located control unit which may be connected to a display to enable an operator to monitor the indicators.
    As it is only necessary to continuously transmit data from the sensor device to the centrally located controller, to control the indoor climate, not to receive data from it, the sensor device comprises only (or uses only) a wireless data transmitter, typically RF, and not a receiver. However, it is desired to be able to reprogram the device, e.g. to update firmware, set new limit values or the like. For this purpose, the known sensor device comprises a hardware interface in the form of a BUS interface, a USB port or the like. To access the hardware interface, it may be necessary to 1] a panel from the device. In addition, it is necessary to have a special device at hand to reprogram the device, e.g. a USB dongle or a laptop. To mitigate this problem, it has been considered to replace the hardware interface with, for example, an RF receiver, but this would increase manufacturing costs, the total size of the sensor device, and would increase the energy required to operate the device. Usually, RF reception capabilities require that the RF module of the sensor device be continuously paired with the central unit, which is cumbersome and time-consuming to set up, and requires that the RF module is always in a grounded state with relatively high energy consumption.
    CN 201804019 U discloses a solar powered wind, light and rain sensor with a solar panel to supply the device with energy and a storage battery to store the energy produced by the solar panel.
    TW 201017075 A discloses a solar-powered ventilation device with temperature and humidity sensors that sends signals that control a fan. Indoor and outdoor light sensors control the position of the solar panel so that it faces inward or outward depending on the light intensity.
    Against this background, the purpose of the generation is to provide a climate sensor which is capable of receiving external data, which can be manufactured and operated at a lower cost, can be operated at a lower energy consumption, has small physical dimensions and is easy to program and reprogram. .
    According to the present invention, this object is achieved by providing the features of claim 1.
    The sensor device of claim 1 comprises a solar cell panel having a plurality of solar cells for providing energy to the sensor device. Thereby, a wired energy supply or supply from internal batteries can be avoided, although an internal battery or other means of storing solar energy for later use may be included in the sensor device. An outer surface area of the solar cells of the panel is positioned so that light, e.g. Sunshine or light from artificial light sources such as lamps can shine on it to produce energy.
    The solar cells provide energy to the sensor device and are connected to a processor unit. The solar cells and the processor unit thus constitute a photo or light sensor which can receive data from a modulated light signal directed at the solar panel. The modulated light signal contains data for the sensor device, preferably data for setting up the sensor device. A selected number of the solar cells are arranged to receive the modulated light signal when the light signal is directed to the solar panel. The processor unit measures fluctuations in the electrical output of the selected number of solar cells caused by the modulated light signal shining on the solar cells so that the sensor device is able to receive the data contained in the light signal. The processor can decode the signal and send the data to the storage of the device for storing, for example, new settings. The new settings can then be used to operate the sensor device.
    In conclusion, the sensor device can be programmed or reprogrammed by optical communication using the solar cells so that a wireless receiver or a hardware interface can be omitted. Thus, the sensor device is capable of transmitting data to an external device via an included electric wireless transmitter, and since the solar panel is used to receive the data signals, no signal receivers such as an RF receiver included in the wireless data transmitter or a separately provided RF transmitter are needed. or a hardware interface, to be included (or to be supplied with energy) in the sensor device. This allows the device to be reduced, it is easier to set up the device and to program or reprogram its settings, production and operating costs are saved and energy consumption is reduced. Since the sensor device does not include an energized, hungry RF receiver that is paired with the central unit, the maximum energy output of the solar panel can be significantly lowered so that a relatively small solar cell panel can be used to provide a sufficient amount of energy to operate the device.
    The dependent claims define embodiments of the invention.
    In one embodiment, the sensor device comprises only a single solar cell panel, of which all solar cells are connected to the processor unit, so that a user or operator will be able to immediately locate the portion of the surface of the sensor device which is intended to receive the light signals and thus a strong signal output. is obtained.
    In another embodiment, the maximum energy output from the solar cells is less than 10 W, more preferably less than 5 W, more preferably less than 3 W, most preferably less than 2 W. To enable the processor unit to measure or detect the data signal from the modulated light signal correctly, it is important that the maximum output from the solar cells sent to the processor unit is small, otherwise the processor unit may not be able to detect the signal. With a large energy output from the solar cells, the fluctuations effected by the modulated light signal may be too small to detect, or the interference from ambient light sources may interfere with the signal.
    In another embodiment, the solar panel of the sensor device receives the modulated light signal from a display screen or camera flash of a mobile phone and / or a handheld camera. Preferably, the mobile phone or camera is a smartphone in which application software installed on the smartphone enables conversion of user input entered on the mobile phone or camera into the modulated light signal. Preferably, the data is contained in the modulated light signal setup data, wherein the processor unit programs the sensor device to transmit data via the wireless data transmitter to a specific external device. Using a smartphone is advantageous, as a user or operator of the sensor device will often already carry a smartphone on his person. Therefore, the inconvenience of bringing special equipment, such as a laptop or USB dongle, to set up the sensor unit is avoided. The operator can simply retrieve his smartphone, for example, enter desired limit values or other setup data in the smartphone application software designed for this purpose, and the smartphone application software converts the data into modulated light signals. The application software may include different setup profiles for setting up different sensor devices so that a user can individually set up, store and switch between the profiles simultaneously.
    During the programming operation, the modulated light signal is transmitted from a light source by the smartphone, ie. from either the display screen or preferably the camera flash, which is typically located on the back of the telephone, where the operator points the light source toward the solar panel on a front of the sensor device. If the sensor device comprises only one relatively small solar cell panel, it is easy for a user to point the light signal correctly to the panel to ensure that the light signals are detected by the sensor device.
    The sensor device receives the modulated light signal via the solar panel and the processor. The sensor device preferably continuously records fluctuations in energy output which can be achieved with the solar cells of the solar panel. The electrical output measured by the processor unit from the solar cells may contain energy level modulation, voltage, current, or any other appropriate value.
    In the drawing, FIG. 1 schematically shows an embodiment of a climate sensor device SD according to the invention.
    The sensing device SD according to FIG. 1 is used to measure climate indicators such as temperature, humidity, rainfall intensity or wind strength. Two electronic indicator sensors 7 are included in the climate sensor SD for measuring the climate indicators. A wireless data transmitter in the form of a wifi transmitter 3 is included for wirelessly transmitting measurement data from the indicator sensors 7 to an external wifi data receiver in the form of a central control unit 6. The wifi transmitter may be included in the form of a wifi device which also has data reception properties but where these are disconnected.
    The sensor device SD is located in a room or zone of a building, and similar sensor devices SD1 - SD3 are placed in other rooms or zones of the building and also transmit wireless measurement data from the corresponding rooms or zones to the control unit 6.
    The climate sensors 7 are connected to a processor unit of the sensor device SD in the form of a microprocessor 2. Alternatively, the processor unit may comprise two or more separate processor units or microprocessors, which handle various tasks such as data processing, data logging, data transfer and / or data reception. Control unit 6 uses the measured and transmitted data to control indoor climate control systems 8, such as heating, cooling and ventilation systems, in the relevant rooms or zones. The sensor device SD also includes a memory for storing device settings and / or measurement data. The memory may form part of the microprocessor 2.
    The sensor device SD is mounted on a wall with climate sensors located inside the device. Alternatively, climate sensors may in principle be located in one or more places in the rooms or zones of a building in which it is desired to measure an indoor climate indicator, where the sensors send measurement data to the sensor device.
    The sensor device SD comprises a single photovoltaic panel 1, comprising a total of four photovoltaic cells 1a, all connected to the microprocessor 2, the photovoltaic cells 1a producing operating energy for the microprocessor 2 as light shines on the photovoltaic panel. The sensor device SD may comprise a battery for storing solar energy when there is light or sunshine, and to provide the stored energy for the sensor device SD when there is a need due to lack of light shining on the solar cell panel 1.
    The four solar cells 1a are arranged to receive a modulated light signal which comprises data for input into the sensor device SD when the modulated light signal is directed to the solar panel 1. When the energy output from the solar cell 1 is sent to the microprocessor 2, the microprocessor 2 measures the modulation or fluctuations. the electrical output caused by the modulated light signal shining on the solar cells. Thereby, the sensor device SD is capable of receiving the data contained in the modulated light signal.
    The modulated light signal is transmitted by an operator by means of an LED flash 4a of a smartphone 4. Preferably, data transmitted through the light signal comprises data for setting up the sensor device SD, in particular information such as the IP address of the control unit 6, to which the sensor device SD shall transmit wirelessly. measurement data, and information related to the locations of the climate sensors 7 of the sensor device SD.
    The modulated light signal sent to the sensor device SD is modulated so that it is easy to detect for the sensor device SD that a signal has been sent and which data the signal contains. It is preferred that the signal consists of (and the signal sensor hardware of the sensor device is arranged to receive) frequency modulated signals, i.e. use of on / off pulse frequency modulation to avoid misinterpretation of signals of varying light intensity. However, modulation may include other signal modulation types, such as pulse length modulation or modulation of other characteristics of the light signal. Signals of varying light intensity can be difficult to obtain in practice, since a flash can typically only be set to on or off, and the light intensity depends on the distance and relative position of the light source. Preferably, the signal code is effective and with a low error margin for the sensor device and smartphone used. Morse code can be used to modulate the light signal.
    Initially, ie. prior to transmitting the signal containing the input data to the sensor device, a short modulated light signal code may be sent to the solar cell panel to enable the processor of the sensor device to identify when a signal is received. For example, this initial signal may consist of three short and three long light pulses of a specific length. Upon receiving this encoded signal, the signal recognition software of the microprocessor 2 prepares for and records the following electronic signal sequence containing the data sequence. Similarly, the coding sequence can be completed with a short coded signal, similar to the initial code. The sensor device SD can transmit a visible and / or audible signal to indicate that data has been received, that an error has occurred and the like.
    In general, the wireless transmitter of the sensor device SD can send a wireless signal to the mobile device which is used to transmit the modulated light signal. This signal may comprise the received data and may be compared with the data sent from the mobile device to ensure that the correct signal has been received. The wireless signal may also simply contain information such as a signal received, progress of data reception, data reception completed, and / or error messages. The mobile device can then visibly or audibly convey this information to the operator or user.
    It may also generally be possible, for example, to download an updated firmware version to a smartphone and to send it to the sensor device in the same manner as described above.
    The sensor device according to the invention may have spatial dimensions of less than 10x10x4 cm, preferably about 8x8x3 cm. In the latter case, the solar panel may have a size of about 5x8 cm with a maximum energy output of 0.5 to 1 W.
    Those skilled in the art will be able to construct the sensor device of the manufacture based on the foregoing description using known standard components such as electronic sensors, microprocessors and other electronic circuits, etc. Also, those skilled in the art will be able to program the software needed for, e.g. to perform measurements, send signals, etc.
    examples
    The following two examples are included to show the benefits of the generation in terms of energy consumption and solar panel area size.
    In a first schematic example, a climate sensor device is arranged in a room for measuring an indoor climate indicator. The device comprises a temperature sensor for measuring room temperature, an RF data communication module (receiver and transmitter) for wireless communication with a central external device, a processor unit and a solar cell for supplying the device. The temperature sensor is a PTC resistor with a negligible operating energy requirement. The RF module is of the RTX4100 type manufactured by RTX and is paired with the central unit so that it is ready to receive data from the central unit, requiring a base energy consumption of 0.8 mW. The RF module transmits measurement data to the central unit every 30 minutes, further requiring an average energy consumption of 0.04 mW, which makes the total average energy consumption to 0.84 mW. The solar panel comprises a number of SLMD121H04 solar panel modules manufactured by IXYS with a surface area of approximately 5 cm2. At a selected expected average level of light incident, one panel module produces an average energy output of 0.06 mW. Accordingly, the number of panel modules required to produce the accumulated mean energy demand of the sensor device is at least 0.84 mW / 0.06 mW = 14, whereby the required solar panel area is at least 14x5 cm2 = 70 cm2.
    In another schematic example, a similar climate sensor device is envisaged, the sensor device being, however, according to the present invention. The second sensor device is similar to the first sensor device except that the photovoltaic panel is connected to the processor unit and is adapted to receive a modulated light signal comprising data according to the output. Consequently, the RF module is not paired with the central unit, as it can instead receive data from modulated light shining on the solar panel. Therefore, the RF module has a base energy consumption of 0 mW. The RF module still transmits measurement data to the central unit every 30 minutes, requiring an average energy consumption of 0.04 mW, making the total average energy consumption to 0.04 mW. With an energy output of one panel module of 0.06 mW, the number of panel modules needed to produce the accumulated average energy demand of the other sensor device is at least 0.04 mW / 0.06 mW = 0.67, ie. a single panel module is sufficient. Thus, the required solar cell panel area is 1 x 5 cm 2 = 5 cm 2 or 14 times smaller than that of the first sensor device. This solar panel area would even suffice if the sensor device also included, for example, a CC> 2 sensor, which usually requires an operating energy of less than 0.01 mW.
