Abstract

PURPOSE:To improve a load equipment control response by selecting the state information destination of the monitor input terminal of a terminal equipment and controlling a load equipment directly between terminal equipments without passing through a master device. CONSTITUTION:When the master device 1 generates a control request for a terminal equipment 2e, a control signal having a transmission origin address and a transmission destination address is sent from the master device 1 to a line 5. When the output signal is inputted to a power control circuit 7e, the power control circuit 7e controls power supply to the load equipment 3e according to the input data part. When said output signal is inputted to the monitor input, on the other hand, the state of the monitor input terminal is read by the terminal equipment 2e and then a monitor signal is sent from the terminal equipment 2e which is set in a normal mode to an equipment which has the transmission destination address of a last received telegraphic message, i.e. the master device 1.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to a remote control device.

[Conventional technology]

FIG. 5 shows, for example, a conventional remote control device disclosed in Japanese Patent Publication No. 60-3]307. In the figure, reference numeral 1 denotes a sharp device that manages the system by synchronizing the entire system. Further, the address of the terminal device to which the control manual switch is attached and the program of the control correspondence/subordination relationship between the control manual switch and each terminal device are set. Terminals 2a, 2b, and 2c each have a monitoring input terminal, and receive a control signal from the sharp tool 1, and also notify the base unit 1 of the status of the monitoring input terminal. Each of the terminals 2a to 2c has its own address. 3a is a load device controlled by the terminal device 2a;
b is a load device controlled by the terminal device 2b. 4 is a control manual switch connected to the monitoring input terminal of the terminal device 2b, and 5 is a line for electrically transmitting signals.

Next, the operation will be explained.

(i) When the sharp device 1 sends out a control signal having the address information of the operation terminal 2a from the main unit 1 to the line 5+, for example when controlling the load equipment 3a, the sent address information is transmitted to the line 5+. The terminal device 2a that matches the address receives the control signal, and controls the load device 3a to be controlled according to the content of the control information of the received control signal.

(ii) Operation when controlling a load device 3C connected to the terminal device 2C using the control human power switch 4 attached to the monitoring input terminal of the terminal device 2b. The on/off state of the monitoring input terminal of the terminal device 2b is As a monitoring signal, terminal device 2b
When the signal is sent to the sharp instrument 1 via the line 5, the sharp instrument 1 that has received the monitoring signal extracts only the required monitoring information from the monitoring signal and updates the contents of the program set in the sharp instrument 1. Accordingly, the destination of the control signal, that is, the terminal device 2c, and the control content are determined. Then, from the main unit 1 to the track 5-
1-, when a control signal having address information of the terminal device 2C is sent, the terminal device 2C whose sent address information matches its own address receives the control signal and transmits the control information of the control signal. The load device 3c to be controlled is controlled according to the content of the load device 3c.

[Problem that the invention seeks to solve]

Since the conventional remote control device is configured as described above when controlling, for example, the load device 3C using the control manual switch 4, it is difficult to improve the control response beyond that. Furthermore, when a power line is used instead of the line 5, the communication speed is suppressed to a considerably low speed in order to ensure the reliability of power carrier communication, and as a result, there is a problem that the load equipment control response is significantly deteriorated. there were.

The present invention was made in order to solve the problems as described in ``-'', and an object of the present invention is to obtain a remote control device that can improve load equipment control response.

[Means for solving problems]

The remote control device according to the present invention includes a base unit, a plurality of terminal units connected to the base unit and having monitoring input terminals to which switches or various sensors are connected, and load equipment connected to each terminal unit. a remote control device comprising: a first setting means for setting a destination address for transmitting the state of the monitoring input terminal to a source address of a message received last time; A second setting means is provided for setting the destination address to which the status is to be transmitted from the self address to an address determined according to a scheduled rule.

[Effect]

In the remote control device according to the present invention, the first setting means sets the destination address for transmitting the state of the monitoring input terminal to the source address of the last received message, and the second setting means sets the monitoring input terminal to the source address of the message received last time. Set the source address for transmitting the terminal status from the self address to an address determined according to the schedule rules.

〔Example〕

FIG. 1 shows an embodiment of the invention. In the figure, ■,
4.5 does not show the same parts as FIG.

2d, 2e, and 2f are terminal devices. 6d, 6e, and 6f are destination selection switches (first setting means, second setting means), which are connected to the terminals 2d to 2f, respectively, and set the normal mode or the three-way ft1lJ control mode. It is.

The bending normal mode is a mode in which the status of the monitoring input terminal is sent to the device that has the sender address of the message that each terminal received last time, and the three-way control mode is in which the status of the monitoring input terminal is sent to each terminal. This is a mode in which the device has an address determined from its own address according to the rules shown in FIG. 3.

The format of the control signal is as shown in FIG.

Power control circuits 7d and 7e are connected to the terminals 2d and 2e, respectively, and control the power supply to the load devices 3d and 3e, respectively. 8f is a display device, and the terminal device 2f has the control manual switch 4.
The controller is connected to the controller and remotely monitors the control status of the load equipment being controlled.

Next, the operation will be explained.

It is assumed that the terminals 2d and 2e are set to the three-way control mode by the destination selection switches 6d and 6e, respectively, and the terminal 2f is set to the normal mode by the destination selection switch 6f.

(a) Operation when the sharp tool 1 controls, for example, the load device 3e In this case, control is performed according to the communication sequence shown in FIG. In other words, when a control request is issued to the terminal device 2e from the sharp device 1, the sharp device 1 sends the source address (OOH
) and the destination address' (02H) is transmitted on line 5. Then, the terminal device 2e changes the destination address (02H) of the control signal to its own address (02H
), this control signal is received, and an output signal corresponding to the contents of the data section shown in FIG. 2 is outputted from the output terminal to the power control circuit 7e and the supervisory power.

When the output signal is manually input to the power control circuit 7e, the power control circuit 7e controls the power supply to the load device 3e based on the input data part. On the other hand, when the output signal is manually input to the monitor, the status of the monitor input terminal is read by the terminal 2e, and the terminal 2e, which is set to the normal mode, outputs the monitor signal from the previously received telegram. Source address (OOH)
The information is sent to the device having the following information, that is, the sharp instrument 1. The sharp device 1 monitors the status of the load device 3e connected to the terminal device 2e based on the content of the received monitoring signal.

(b) The operation when the sharp device 1 controls the load device 3d connected to the terminal device 2d, for example, is essentially the same as the operation in the case of (a) above, so a redundant explanation will be omitted. The communication sequence in this case is shown in FIG.

(C) The terminal ay is controlled by the control human switch 4 of the terminal 2f.
2. Operation when controlling the load device 3d connected to the load device 3d. In this case, control is performed according to the communication sequence shown in FIG. That is, when the human control switch 4 is operated, an output signal is first input from the human control switch 4 to the monitoring input terminal of the terminal 2f, and this state is read by the terminal 2f, which is set to the three-way control mode. , Then, the destination address is determined by the terminal device 2f.

This destination address is r81, which is the address of the terminal 2f.
Since HJ, according to the rules shown in Figure 3, ro I H
It becomes J. Once the destination address is determined, the determined destination address OIH is attached to a supervisory signal, and this supervisory signal is transmitted to the line 5 by the terminal 2f. Then,
Since the terminal device 2d's own address matches the destination address of the supervisory signal, it receives this supervisory signal and sends an output signal corresponding to the contents of the data part of the received supervisory signal to the power control circuit 7d via the output terminal. And it is output to the monitoring human power of the terminal device 2d. Then, when the output signal is manually input to the power control circuit 7d, the power control circuit 7d controls the power supply to the load device 3d. On the other hand, when the output signal is manually input to the monitoring input terminal of the terminal device 2d, the destination address is determined by the terminal device 2d, which is set to the three-way control mode, according to the rules shown in FIG. The destination address is ro, which is the address of the terminal device 2d.
Since it is 1 HJ, it becomes r81 HJ. and,
When the supervisory signal with this address is sent to the line 5 by the terminal 2d, the terminal 2f receives the supervisory signal because the destination address of the supervisory signal matches its own address. An output corresponding to the contents of the data section is manually input to the display 8f via the output terminal. The status of the load equipment is monitored by this indicator.

Note that the destination selection switch allows you to select the status notification destination of the monitoring input terminal, so in a system that does not particularly require control responsiveness, as mentioned above, you can set it to normal mode and concentrate more on the sharp device 1. It is also possible to control. Furthermore, these can be mixed in the same system depending on the purpose, increasing the flexibility of system design.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to select the status report destination of the monitoring input terminal of the terminal, and
Since the load equipment is controlled directly between the terminal equipment without the intervention of any sharp equipment, it is possible to obtain a remote control device that can improve the load equipment control response.
