    15 20 25 30 2 Additional power stations, so-called distribution centers, final distribution centers and withdrawal centers are connected in a hierarchy to the input center. The choice of size and capacity at the various exchanges is made on the basis of an estimate of the power output at different locations in the system. Even if the capacity of the system is not used to the maximum at all times, it must still be possible to periodically take out a high power, for example when energy-intensive machines are used for limited periods.
    The total amount of energy consumed is measured at the input center, where the incoming cable is connected. The measurement result is the basis for the electricity supplier's charging.
    Experience has shown that energy consumption during construction is high.
    This is especially true if the consumption is set in relation to the consumption during the future operation of the building. With today's efforts to build energy-efficient houses for both environmental and purely economic reasons, it is thus desirable to reduce energy consumption even during the construction period.
    One problem so far has been that it is unclear where and how savings can be made during the construction period. Many people are involved in the project and it is difficult to get an overview of where the energy is consumed. One often has the spontaneous perception that all energy-consuming measures taken are absolutely necessary.
    PROBLEM STATEMENT The object of the invention is thus to ensure that the consumption is simple and clearly traceable, so that it is clear where saving measures can best be implemented.
    TROUBLESHOOTING The object underlying the invention is achieved if the initially specified control panel is characterized in that it comprises an energy meter for sensing the consumed energy, a logger for recording associated values of energy consumption and time and a transmitter for local transmission of the registered values. 10 15 20 25 30 Entering the system, the goal is achieved if this is characterized by the fact that it comprises an Internet-connected computer.
    Regarding the method, the objective is achieved if this is characterized by sensing of consumed energy in each exchange at a selectable number of times, registration of corresponding values of energy consumption and times, and transmission to other centers of the registered, associated values.
    Additional advantages are achieved if the control panel, the system or the method are additionally given one or more of the features according to the subclaims. sAiviix / PREPARATION OF DRAWING FIGURES The invention will now be described with reference to the accompanying drawings. These show: fi g l a schematic sketch of a house during the construction period, in which a network of exchanges is arranged; 2 g 2a and b an example of an individual control panel included in the system, seen straight ahead and straight from the side; fi g 3 a schematic view of the system according to the invention; and 4 g 4 is a diagram illustrating the use of the system.
    PREFERRED EMBODIMENT I fi g 1 shows a house 1 under a building in section, as an example of a construction site where the design according to the application is applicable. 10 15 20 25 30 4 An incoming cable 3 is drawn from an electrical cabinet 2 for input of electrical energy from an electricity supplier. The cable 3 is connected to an input exchange 4, from which additional cables 5 are routed to supply additional exchanges 6 at the construction site. Machines 7 can also be connected directly to the feed center 4.
    The other exchanges 6, which are connected to the input exchange 4, have varying sizes and capacities. In general, they are referred to as distribution centers, final distribution centers and withdrawal centers. They are selected and connected with regard to the need for power that is believed to arise at each point or in the subordinate exchanges.
    The energy used is used, for example, for lighting, heating, dehumidification in buildings and for the operation of various machines 7 and tools 16 at the construction site. Examples of such machines 7 and tools 16 are cement mixers, grinding machines, drilling machines and the like. In the construction of the system for temporary energy supply, the system according to the invention functions essentially as the older technology.
    The significant difference in relation to older technology is that according to the invention the energy consumption can be monitored and derived to the respective central 4, 6 where it is consumed. This makes it possible to see where and for what energy is consumed. In the system according to the invention, it is also possible to see when the energy is consumed, by registering associated data for energy consumption and times.
    When these data are presented in a clear manner, as will be described in more detail below, it can be seen whether a certain type of consumption in a certain place is unnecessarily high and one can thereby consider measures to achieve savings.
    Figures 2a and 2b show an example of a central 4, 6 which is included in the system according to the invention. A cable 3, 5 is connected to the control panel 4, 6 with incoming electricity, and to the control panel 4, 6 a number of machines 7, 16, cables for lighting or subordinate control panels 6 can then be connected in one or some of the sockets 8 which are arranged in central 4, 6. The sockets 8 can be of different types with different voltages, different numbers of phases and designed for a certain maximum current. On the basis of the maximum current and voltage, the maximum power that can be connected to the respective socket 8 can also be calculated.
    In each control panel 4, 6 there is, as shown in fi g 2a, an energy meter 9, which senses the current consumption in the respective control panel 4, 6. This means that not only the consumption of such machines 7 and devices 16 which are connected directly to the exchange 4, 6 is registered, but also the consumption in sub-exchanges 6. The consumption in these sub-exchanges 6 is registered in the same way, which means that the consumption which relates directly to the exchanges' 4, 6 connected units can be distinguished from the consumption of the sub-exchanges. arranged centers 6.
    In the exchange 6 there is also a logger 10, in the same way as is the case in all exchanges 4, 6.
    The logger 10 registers pulses from the energy meter 9 and sums these. At the same time, loggem registers 10 times, so that time-marked data for energy consumption is obtained. The frequency of time registration, ie how often the time marking takes place, is adjustable, so that you get a quantity of data that is possible to process, and which gives the desired resolution with respect to time. For a certain application, it is interesting to register time-marked values once an hour, while other applications require registration of the values much more often, for example every five minutes, or at larger intervals, for example once a day.
    The control panel 4, 6 further contains a transmitter 15 for local transmission of the registered, time-marked values of the energy consumption. In the preferred embodiment, the transmission takes place as a superimposed electrical signal on the cables in the system at the construction site. In addition to the current position of the energy meter 9 and the associated time, the signal also indicates the identity of the control panel 4, 6, so that it is possible to determine where the time-marked values of the energy consumption come from. The signal, which in the preferred embodiment is electrical, is spread throughout the system so that it can be perceived everywhere, in all cables 5. In the preferred embodiment, the logger 10 and the transmitter 15 are integrated into a single unit, but the two functions can also be separate.
    Fig. 3 shows a schematic model of the system of exchanges. In one of the exchanges 4, 6 there is a data collection unit 11 for collecting the time-marked data which is transmitted by all exchanges 4, 6 included in the system. Furthermore, the same exchange 4, 6 has a communication unit, for communication with the outside world. outside the system. This central 4.6 can be located anywhere in the system, since the time and identity marked values are possible to perceive anywhere in the system.
    In the preferred embodiment, the data acquisition unit 11 sends out a question or request for information to all exchanges 4, 6 in the system at regular intervals, in the preferred embodiment once an hour. The above-mentioned superimposed signals from the transmitters 15 in the respective exchanges 4, 6 are transmitted in response to this question or request.
    The emitted values are registered in the insertion unit 1 1.
    From the collection unit 11, the collected values are transferred to the communication unit 12, which in the preferred embodiment sends the registered values to an Internet-connected computer 13. Since the communication with the Internet-connected computer 13, which may be at a long distance from the construction site, does not take place in real time, ie as soon as the time- and identity-marked values of consumption have been collected, no constant connection to the Internet is needed, which in many cases is cost-effective.
    The collected and transferred values are processed and compiled, so that they can be presented in a clear manner on a website, which is accessible via the Internet. As mentioned above, each control panel 4, 6 has its own identity, and with knowledge of which control panels 4, 6 are included in the current system and how they are connected in relation to each other, one can also understand in which system the energy is consumed. and at what time this occurs.
    In Fig. 3, the system is shown, as mentioned, schematically, and the input center 4 is shown at the top of a hierarchy of subordinate exchanges 6. The exchanges 4, 6 are connected by cables 5.
    The data collection unit 11 and the communication unit 12 can be placed anywhere in the system, since the information on the consumption of the various exchanges 4, 6 is available in the whole system. It is conceivable that all (or more) exchanges per se are provided with data collection units 11 and communication units 12, but that only one data collection unit 11 and a communication unit 12 are used in a certain system. The entire system is thus mapped with a single designated data collection unit 11 and communication unit 12, respectively. The advantage that the exchange 4, 6 with these units 11, 12 can be located anywhere in the system is that a place with good conditions for communication with the outside world, such as good mobile coverage, can be chosen. The information is transmitted, preferably via the mobile network, to a computer 13 with an internet connection, via an external or internal modem 14.
    In the computer 13, the transmitted information is processed and compiled, so that it can be presented in a clear manner on a website which is accessible via the Internet. On the website, the information is presented after logging in by an authorized user, for example in diagram form for one or fl your exchanges at a time.
    An example of a diagram is shown in fi g 4. In the diagram we can state that the energy consumption in central 1 is constant during the period studied. Such energy consumption can be typical of constantly switched on lighting or heating elements. To reduce consumption and thereby make savings, both in terms of cost and the environment, for example motion detectors can be installed so that the lighting is only switched on where people are moving, alternatively that time is installed, so that the lighting is turned off during periods when work is not performed at the construction site. If the consumption refers to a heating element, thermostats can be arranged, which switch off the element when the temperature is sufficient. The results of the measures will be immediately visible on the same website as soon as the measures have been taken, which can stimulate further savings.
    In central 2, the energy consumption varies. Because there is a clear connection to time, there is an opportunity to realize why energy consumption is occasionally high, and once this has been realized, appropriate measures can also be taken.
    The diagram in fi g 4 shows the consumption hour by hour, but it is possible to choose the extent of the diagram in such a way that you get an overall picture of the consumption, for example during a week, a month, parts of a year or the whole year. ALTERNATIVE EMBODIMENTS In the preferred embodiment, as described above, each control panel 4, 6 logger 10 transmits signals with information about the energy consumption of the existing cables 5 between the control panels 4, 6. This works well in the case of electrical energy to be measured. An alternative approach is for the local transmission of signals from the respective exchange 6 to take place via radio with a limited range, instead of via cable. The data collection unit 11 and the logger 10 are thereby adapted to such a transmission of time-marked data. This type of local transmission and collection of time-marked consumption data is mandatory for use also with energy sources other than electricity, for example in cases where district heating is used temporarily in punkter your points, for example for heating and drying a newly built building.
    The system according to the preferred embodiment, or some alternative embodiment, can be modified so that sensors, such as temperature sensors, are arranged in the system and are arranged to emit measured values in the same way as for the registered values for energy consumption. In this way, the conditions at one or platser your places in the system are monitored and an alarm can be issued and the values exceed or sign the predetermined threshold values. Some measures may be taken automatically, such as an adjustment of the heating.
    The invention can be further modified within the scope of the appended claims.
