In this system, a controller 2 and an interface unit (hereinafter abbreviated as IFU) 3 are connected via a control signal line 1, and this IFU 3 and a terminal device 4 are connected using the above-mentioned HA terminal.

The control signal line 1 connecting the controller 2 and IFU 3 uses a home bus system or other transmission system. IFU3 transfers control data and monitor data
and the controller 2, and between the IFU 3 and the terminal device 4, a control signal C based on the above connection condition general rules is transmitted.
and monitor signal M are exchanged via the HA terminal.

Here, the IFU 3 is composed of a transmission control circuit 5 that performs transmission system signal processing, and a signal processing circuit 6 consisting of a CPU that transmits and receives control signals C and monitor signals M to and from the terminal equipment 4. 6 receives a control signal C to the terminal device 4 through the photocoupler 7a and the HA terminal 8, and receives an operation monitor signal M from the terminal device 4 through the HA terminal 8 and the photocoupler 7b.

The HA terminal 8 is composed of a pair of control signal terminals and a pair of monitor signal terminals, for example, as shown in FIG.
For example, 4MA terminals are provided in pairs and correspond to the HA terminal 8.
It is connected to the HA terminal 8 on the terminal device 4 side via the connection line 9 of the terminal device 4 .

! It is configured as shown in J(c), and when the photocoupler 7b is energized, the terminal device 4 is in an operating state, and when it is not energized, it is in a stopped state.

[Problems to be Solved by the Invention] As described above, when the HA terminal 8 of the JEM1436 standard is used, in the remote monitoring and control system, the 1M1l signal C sent from the IFU 3 to the terminal device 4 is a binary signal that reverses the operating state of the terminal device 4. Therefore, when increasing the number of control and monitoring points, it is necessary to increase the number of HA terminals 8, and there is a problem that the number of connection lines 9 increases by the increased number.

Furthermore, if a control signal of another format is used to solve such problems, there is also the problem that the terminal device 4 having the HA terminal specification cannot be supported.

The present invention was made in view of the above-mentioned problems, and its purpose is to be able to control multi-control type terminal equipment without increasing the number of connection lines, and also to be able to control terminal equipment with HA terminal specifications. The purpose is to provide a remote monitoring and control system that can respond to

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a standardized remote monitoring and control system comprising a controller, a terminal device, and an interface unit interposed between the two. A signal generating means for creating a signal in parallel with multiple bits in the same format as a binary control signal to be sent to a terminal device with home automation terminal specifications, and a signal equivalent to a monitor signal from the terminal device with home automation terminal specifications in multiple bits in parallel. and a signal input means for capturing the signal,
A control signal based on a combination code of signals of each bit outputted from the signal generating means configured based on control data from the controller is outputted to a multi-control type terminal device, and each signal is inputted from the multi-control type terminal device. The monitor data based on the monitor signal constituted by the combination code of each bit signal input to the means is transmitted to the multi-control terminal equipment, and the one bit signal output from the signal generating means is transmitted to the home automation system. A control signal to a terminal device with terminal specifications is obtained, and a one-bit signal taken into the signal input means from the terminal device with home automation terminal specifications is taken in as a monitor signal of the terminal device with home automation terminal specifications, and monitor data can be transmitted to the controller. It is equipped with a built-in interface unit.

[Operation] According to the present invention, when controlling a multi-control type terminal device, the interface unit generates a control signal consisting of a code made up of a combination of multi-bit signals created by the signal creation means. At the same time, a combination code of multiple bits of signals taken into the signal input means is used as a monitor signal, so multiple control and monitoring of terminal equipment can be performed with a small number of connection lines, and moreover, it can be created by the signal creation means. Since the signal has the same format as the control signal of a conventional terminal device with a home automation terminal specification, a control signal corresponding to the control signal of a terminal device with a home automation terminal specification can be created with a single bit signal, and it can also be captured by a signal input means. Since the signal is in the same format as the terminal device with home automation terminal specifications, a single bit signal can be taken in as a monitor signal for the terminal device with home automation terminal specifications, and as a result, the terminal device with home automation terminal specifications can also be controlled and monitored. The same interface unit can control and monitor multi-control type terminal equipment and home automation terminal specification terminal equipment.

In response to this control signal, a "H" signal is applied to the gate A of the decoder circuit 21 of the multi-control terminal device 11, and this signal is output as a stop signal to the motor drive circuit to cut off the current to the motor. , the closing of the electric shutter stops as shown in Fig. 2 <a). On the other hand, since the current to the motor disappears, the detection output of the current detection circuit 20 disappears, and the output of the Noah gate N becomes H". . At this time, the output of the Nant gate NA is also "L" because both switches sw, , sw are off, and therefore a high signal is output from the AND gate AN to the encoder circuit 18.
