DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described.
FIG. 1 is an external view of a housing monitoring system according to the present invention, where 1 is a distribution board and 2 is an intercom. The distribution board 1 can incorporate a power measuring device, an integrating wattmeter, a voltage / current detector, a leakage detector, an overcurrent detector, a power factor measuring device, and the like. The distribution board 1 is connected to at least one of various measuring devices such as a gas sensor 3, a smoke sensor 4, a heat sensor 5, a gas meter 6, and a water meter 7. In addition, an intruder detection device, a clock, electricity, gas, water fee calculator, etc. may be connected. In FIG. 1, various measuring devices are directly connected to the control unit 8 of the distribution board 1. However, a sensor panel is provided in the middle to connect various measuring devices, and the sensor panel and the distribution board are connected by transmission means. May be.
[0009]
The intercom 2 and the distribution board 1 are connected by a transmission means 9 capable of transmitting and receiving signals in both directions. The transmission means 9 may be either wired or wireless. In FIG. 1, a transmission control unit is provided in both the interphone 2 and the distribution board 1, and they are connected by a transmission line 10.
[0010]
The intercom 2 includes a display unit 11 and an operation unit 12. The display unit 11 is, for example, a television screen, and the interphone 2 displays a visitor image during a call with the handset 13 installed at the entrance or the like. Can be displayed.
[0011]
For example, when it is desired to display the real-time power consumption measured in the distribution board 1, when a user operates the operation unit 12 of the intercom 2 to switch the display, a request signal is transmitted from the control unit 14 of the intercom 2. Is transmitted to the control unit 8 of the distribution board 1, and a real-time power consumption signal is returned from the wattmeter connected to the control unit 8 via the transmission means 9. When the reply signal arrives normally, an affirmative signal is sent from the control unit 14 to the control unit 8, and real-time power consumption is displayed on the display unit 11 of the intercom 2.
[0012]
Other information on the distribution board 1 includes monthly integrated electric energy, weekly integrated electric energy, daily integrated electric energy, peak electric energy, power warning setting value, etc. The display unit 11 is displayed by switching the display by operating the unit 12. Further, by the same operation, the measurement results of various measuring devices such as the gas sensor 3, the smoke sensor 4, the heat sensor 5, the gas meter 6, and the water meter 7 connected to the control unit 8 of the distribution board 1 are also displayed on the display unit 11.

In addition, by switching the display by operating the operation unit 12 of the interphone 2 as described above, various data are transmitted to the interphone 2 from the control unit 8 of the distribution board 1, but the switching is frequently performed. Therefore, it is preferable to shorten and transmit various types of less important data to the interphone 2. For example, the usage amount of electricity, gas, and water is replaced with data of one character such as “F”, “M”, “S” meaning “large”, “medium”, “small”, and transmitted. The display unit 11 displays only the usage amounts “large”, “medium”, and “small” in real time. In this way, the usage state can be displayed in real time without imposing a burden on the transmission apparatus. Data representing actual usage may be sent at relatively long time intervals.
[0015]
The various measuring devices described above are connected to the control unit 8 of the distribution board 1. However, it is preferable to set an address to each input unit by using a dip switch or the like so that the measuring device can be expanded. .

Further, in the present invention, setting information for various measuring devices connected to the control unit 8 of the distribution board 1 can be input from the operation unit 12 of the intercom 2. Specifically, the working voltage, line style, rated current of the breaker, calendar setting, time setting, and the like. In addition, setting of values related to monthly, weekly, and daily power warnings, setting of the start date of power integration for each month, setting of charge charges such as setting of power charge integrated values, and the like are also included. Thus, setting information can be input without going to the installation location of various measuring devices as in the prior art.
[0017]
Furthermore, the operation unit 12 of the intercom 2 can set priorities for various measuring devices, and the control unit 14 built in the intercom 2 temporarily stores the measurement results in the storage device and processes the signals according to the priorities. Is possible. That is, the signal received by the intercom 2 within a certain time temporarily holds the measurement result in the storage device, and the control unit 14 displays and processes a signal with a higher degree of urgency according to the priority order at a certain time interval. It is. For example, with an overcurrent alarm and a warning signal from a smoke sensor, a warning signal from a smoke sensor with a higher degree of urgency is displayed on an interphone and a warning is issued from a speaker (not shown). Further, since the priority order varies depending on the user and the use situation, it can be set from the operation unit of the intercom.
[0018]
In the above description, a single distribution board 1 and a single interphone 2 are connected. However, when there are a plurality of distribution boards 1 and interphones 2, they are specific to the interphone 2 and the distribution board 1. A device identification number is assigned, and the device identification number is transmitted simultaneously when a signal is transmitted. As a result, the state of a plurality of distribution boards 1 and 1 at different locations can be operated and monitored with one intercom 2, and the important distribution panel 1 can be operated and monitored with the interphone 2 from a plurality of locations. become.
