Description

  The present invention relates to a wiring system having a backup function capable of simultaneously transmitting information and load power and allowing the load to function even when a power failure occurs.

  Conventionally, in a system that performs load operation (monitoring) control through a terminal device, a transmission signal composed of a multipolar baseband signal is sent to the terminal device from a central monitoring device by time division multiplexing, and each terminal device transmits this transmission signal. There has been a system for exchanging information and obtaining a power supply for a terminal circuit unit (see Patent Document 1 below).

In this system, an operation terminal provided with operation switches and the like is embedded in a wall surface by using a switch box standardized for an embedded wiring apparatus and a mounting frame corresponding to the switch box. It is designed to be used in the same way as the wall switch. When installing two sets of operation terminals, use a double mounting frame with two mounting windows, attach a series of one side of the mounting frame to a series of switch boxes, and attach the other side to the wall. It has been arranged so that the two operation terminals are provided side by side by arranging the operation terminals on the respective mounting windows. In addition, by bringing the conductive pieces provided between the mounting windows into contact with the lead pieces of the operating terminal provided on the mounting windows on both sides, from one operating terminal (switch box side) to the other operating terminal. The signal line is sent and wired.
Japanese Patent No. 3136006 (paragraph numbers 0004, 0005, 0015, FIG. 1, FIG. 37)

  By the way, although the above-mentioned system can supply power to the terminal circuit unit of the terminal device by the transmission signal, for example, the power supply to the load controlled by the control terminal device due to the limitation of the current capacity of the signal line, etc. In each installation location, the power is supplied from a commercial power source. Therefore, since it is only necessary to connect two signal lines between the terminals, the wiring of the signal lines can be reduced, but the arrangement of the power supply lines with respect to the load remains the same, so the control terminal The installation place of the vessel is limited.

  Further, if the power supply from the commercial power supply is cut off as in the case of a power failure due to a disaster or the like, the function of the entire wiring system is stopped, and for example, crime prevention or disaster prevention becomes difficult.

  The present invention has been made in view of the above-described points, and an object of the present invention is to ensure a power path and an information path of the functional module at the same time by simply connecting the functional module to the gate device, and a power failure. It is an object of the present invention to provide a wiring system having a backup function that allows a functional module to function even in such a case.

  The present invention has been made to solve the above problem, and a wiring system according to the present invention includes a gate device having a power path connection port connected to a power line and an information path connection port connected to an information line. A DC drive function module having a connector connected to the power path connection port and the information path connection port of the gate device, and AC / DC conversion for converting AC power into DC power and supplying the DC power to the DC drive function module Means, a power failure detection means, and a backup power supply means for supplying power. When the power failure detection means detects a power failure, the power is supplied to the DC drive function module by the power of the backup power supply means.

  In the wiring system configured as described above, the DC drive function module is connected to the gate device by connecting the connector of the DC drive function module to the power path connection port and the information path connection port of the gate device. is there. Therefore, if the DC drive function module is connected to the gate device, it is simultaneously connected to the power line and the information line.

  Further, normally, AC power sent through the power line can be converted into DC power by the AC / DC conversion means and supplied to the DC drive function module, so that the DC drive function module functions. On the other hand, when a power failure occurs, the power failure detection means detects the power failure, and DC is supplied to the DC drive function module by the power of the backup power supply means. With this power, the DC drive function module continues to function.

  In particular, the backup power supply means preferably supplies DC power converted by the AC / DC conversion means. In this way, since DC power previously converted into DC can be directly used and supplied to the DC drive function module, wiring between the backup power supply means and the DC drive function module can be simplified.

  The DC drive function module has a DC drive unit and first AC / DC conversion means for supplying DC to the DC drive unit, and normally supplies AC power sent to the gate device through the power line to the first AC / DC. The DC power is converted by the DC conversion means and supplied to the DC drive unit, while the backup power supply means is connected to the branch power line that branches in the middle of the power line via the second AC / DC conversion means. Preferably, the DC power converted by the conversion means is charged, and when the power failure detection means detects a power failure, the DC power of the backup power supply means is supplied to the DC drive unit through the information line.

  With such a configuration, versatility is improved by using a power line dedicated to AC power. In addition, at the time of a power failure, DC power from the backup power source means can be directly supplied to the DC drive unit through the information line.

  Furthermore, the power line and the information line are connected to the outside through the distribution board, and the backup power supply means is provided in the distribution board so as to be branched from the power line and electrically connected to the information line. preferable. If comprised in this way, the wiring of the power line and information line between a distribution board and a gate apparatus can be simplified, and it becomes possible to perform work, such as a maintenance, in the distribution board at once. .

  The DC drive function module is preferably an LED module. Since the LED can save power, the power of the backup power supply means can be used for a long time, and the function of the LED can be maintained even if the power failure lasts for a long time. . Therefore, at the time of a power failure, the LED module can be used as a lighting fixture for disaster prevention, for example, for illuminating an evacuee's evacuation route.

  Furthermore, the LED module is preferably connected to a gate device provided in the upper part of the room. If it does in this way, an LED module can be functioned as a main lighting fixture not only at the time of a power failure but at the normal time.

  Still further, the LED module is preferably connected to a gate device provided in the lower part of the room. If it does in this way, not only at the time of a power failure but also at the normal time, an LED module can be functioned as a step lamp which illuminates the step of a pedestrian or the like.

  The DC drive function module is preferably a sensor module. If it does in this way, at the time of a power failure, for example, it can be detected by the sensor module that an outsider has invaded or a fire has occurred.

  Further, an LED module is further provided as a DC drive function module, and when a detection signal from the sensor module is transmitted to the LED module through the information line, the LED module is in a driving state corresponding to the transmitted detection signal. Is preferred. If it does in this way, at the time of a power failure, it will become possible to recognize the detection result of a sensor module easily visually through the drive state (light emission state) of LED.

  Furthermore, it is preferable that the DC drive function module is simultaneously connected to the power line and the information line by connecting the connector to the power path connection port and the information path connection port. The power path and the information path can be secured simultaneously by simply detachably connecting the connector of the functional module to the power path connection port and the information path connection port of the gate device.

  Furthermore, it is preferable that the power path connection port and the information path connection port are modularized to form a connection part, and the connector is modularized so as to fit the connection part. Since the DC drive function module can be detachably connected to any gate device, it is possible to provide a wiring system that is layout-free and excellent in workability.

  Thus, in the wiring system according to the present invention, the gate device has the power path connection port and the information path connection port, and connects the connector to the power path connection port and the information path connection port. Thus, the DC drive function module is connected to the gate device, so that the power path and the information path of the function module can be secured simultaneously only by connecting the function module to the gate device.

  Moreover, not only can DC be supplied to the DC drive function module at normal times, but also DC can be supplied to the DC drive function module by the power of the backup power supply means even during a power failure, and the DC drive function module continues to function. Therefore, unlike the prior art, the power supply from the commercial power supply is interrupted and the function of the wiring system is not stopped, so that the wiring system continues to function, and for example, an effect that crime prevention, disaster prevention, and the like can be achieved.
