[Problem that the invention seeks to solve]

However, in the conventional device described above, even when controlling a plurality of loads 3 that perform exactly the same operation, it is necessary to connect terminal handsets 2 having different addresses to each load 3, and key operations are required. This not only makes the system inconvenient to use, but also causes the address to be used unnecessarily for other terminal handsets 2, which require individual control.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a centralized monitoring device that eliminates the above-mentioned conventional drawbacks, is easy to use on a main operation panel, and is capable of monitoring and controlling a large amount of loads with a simple configuration.

[Failure to solve the problem]

In the present invention, a terminal machine that transmits and receives data with a terminal slave unit is provided, a load that moves in the same way as the load connected to the terminal slave machine is connected to this terminal machine, and all loads are connected to the main operation panel. Exactly the same control is performed.

[Effect]

All loads are controlled in exactly the same way by the main operation panel, so
The main operation panel can monitor and control a plurality of loads that perform exactly the same operation using one key switch and monitor for one terminal slave unit.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 5 denotes a terminal machine that sends and receives data to and from the terminal slave unit 2, 6 a second load that is controlled and monitored by the main operation panel IK via the terminal machine 5 and the terminal slave unit 2, and 7 is a second signal line for exchanging data between the terminal device 5 and the terminal handset 2.

Next, the operation of the central monitoring device having the above configuration will be explained using FIGS. 4 to 6. FIG. 4 shows a flowchart of the terminal handset 2, FIG. 5 shows a flowchart of the terminal mobile device 5, and FIG. 6 is a diagram showing the principle of superimposition of state signals of the terminal handset 2 and the terminal mobile device 5.

The main operation panel 1 sends an address signal and a control data signal to each terminal slave unit 2 by clicking the signal Ifa for each address.
4, and after sending the signal to one terminal handset 2 until the signal is sent to the terminal handset 2 at the next address, the state signal is sent back from the terminal handset 2. By receiving signals from the line 4, the load 3 connected to each terminal handset 2 is controlled and monitored. When the address from the main operation panel 1 does not match its own address, the terminal slave unit 2 sends a signal l1liI7 ( (Connected to the dedicated terminal of terminal slave 2.)
Perform data transmission with. This data transmission is performed every time the terminal handset 2 receives an address that is not its own address, and the predetermined address of each terminal 5 is sent from the main operation panel l and connected to the terminal handset 2. It is cyclically transmitted together with the same control data signal as the signal that controls the load 3.

Therefore, the number of terminal devices 5 connected to one terminal device 2 is the same as the number of times that the terminal device 2 is not called for its own address. When the mobile terminal 5 receives its own address, it sends the state of the load 6 connected to the mobile terminal 5 to the slave terminal 2.

Further, when the terminal handset 2 completes receiving the data from the terminal ammunition 5, it prepares to receive the next address and control signal sent from the main operation panel 1 via the signal line 4. Since the time from when the main operation panel 1 finishes sending the first signal until it sends the next signal is limited, the terminal handset 2 turns on the timer immediately after branching to determine whether it is its own address or not. However, if there is no reply from the terminal device 5 even after a predetermined period of time has elapsed, it is determined that the terminal device 5 does not exist, and preparations are made to import the next data from the main operation panel. do. The state signal from each terminal aircraft 5 is secured in the memory of the terminal slave unit 2.

When the terminal slave 2 receives a signal matching its own address, the terminal slave 2 superimposes the state signal of each terminal 5 and the state signal of the load 3 connected to itself. The principle is shown in FIG. The state signal is a binary representation of "H" level and "L" level, and AND and O for each bit are used.
R is superimposed on the control data signal from the main operation panel 1 or on a predetermined logic. As an example of the former, if a command to drive loads 3 and 6 is transmitted from the main operation panel l, and there is a bit whose status is 1 level when each load 3 and 6 is being driven, the overlapping The logic is to preferentially find the 0L'' level using AND, and
If there is something that is not driving at any time, the final data is “L”
level. Conversely, when a command to stop the loads 3 and 6 is transmitted from the main operation panel 1, the superposition logic uses OR to preferentially find the "H" level, and if even one is driving, the final data is output. Set it to H” level.

Also, as an example of the latter, if there is a bit where the state signal becomes "H" level when an abnormal button is pressed, if there is even one abnormality in that bit, the final state signal is set to "H" level. An OR is taken so that

The superimposed state signals as described above are displayed on the main operation panel l.
will be replied to. For example, in the main operation panel l shown in FIG. 3, multiple loads 3.6 can be controlled by one key switch 12 through the process described above, and the monitor 11 can control multiple Fig. 7 shows an example in which an air conditioner is connected as the load 3゜6 of the above-mentioned central monitoring device, and 8 shows the representative state in which the state signals of the above are superimposed.
This is a sensor connected to the main body).

The signal from the sensor 8 is sent to the terminal handset 2 and the terminal ammunition 5 as the states of the loads 3 and 6. The sensor 8 may be a temperature sensor, an oxygen deficiency sensor, a gas leak sensor, or the like. In this example, one terminal unit 2 is installed in each room A to F, and if two or more air conditioners are installed in one room, the terminal unit 5 is connected to the terminal unit 2. , which collectively monitors and controls multiple air conditioners installed in each room.

Figure 8 shows an example in which illuminators are connected as loads 3 and 6,
In this example, similarly to the example shown in FIG. 7, the illuminators are collectively monitored and controlled by the terminal handsets 2 and terminal devices 5 installed in each of the rooms A to F.

In addition, on each of the above sides, a power line is used as the signal line 4 connecting the main operation panel l and the terminal handset 2, and the signal line 7 is
either use a dedicated communication line, or ■ use a dedicated communication line for signal line 4 and a power line for signal line 7, or ■ use a power line for both signal lines 4 and 7. It's okay.

However, in the case of ■ and ■, the frequency band used is divided to prevent interference between the communication between the main operation panel 1 and the terminal handset 2, and the communication between the terminal handset 2 and the terminal mobile device 50. There is a need.

〔Effect of the invention〕

As described above, in the present invention, a terminal device that performs data communication with a terminal device is provided, and a second load different from the first load connected to the terminal device is connected to this terminal device. and
These first and second loads can be controlled identically by the main operation panel. Therefore, the load monitored and controlled by one key switch on the main operation panel is 1
Not only the first load connected to one terminal slave, but also the second load connected to the terminal transmitting and receiving data with the terminal slave.
This includes multiple loads that perform the exact same operation.
It can be controlled using one key switch and one monitor, which improves the usability of the operation panel, and allows a large amount of load to be monitored and controlled with a small number of key switches.
