Abstract

PURPOSE:To simplify the constitution of equipments on the controlled-side by providing, on the controlling side, a control information transmission part, a loop back information reception part, and a comparing part to compare a loop back control information with a control information, and providing, on the controlled-side, a control information reception part and a control information loop back part, and confirming the reception of the control information based on the result of the comparison by the comparing part. CONSTITUTION:The control information transmission part 2 transmits a control information supplied from a control part to a transmission line 1. The control information reception part 3 receives the control information from the transmission line 1 and outputs it. The control information loop back part 4 transmits the control information received by the part 3 out to the transmission line 1 and returns it. The loop back information reception part 5 receives the control information loop-backed through the transmission line 1. The comparing-part 6 stores the control information transmitted by the part 2, and compares it with the loop-backed control information, and in case of agreement between the two, supplies a reception confirming signal to the control part indicating that the transmission has been normally completed. Thus, since no comparing means or collation means are necessary to be provided on the controlled- side, the equipments there can be simplified and miniaturized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote control method for controlling a remote device using a transmission path.

[Conventional technology]

In conventional remote control systems, after receiving control information on the controlled side, the control information is compared and collated, and a specific signal is returned to confirm reception of the control information.

[Problem that the invention seeks to solve]

As mentioned above, in the conventional remote control system, the controlled side compares and collates the control information, and confirms reception by returning a certain number 13. Therefore, since the controlled side requires means for performing comparison and collation and returning a specific signal, there is a problem in that the configuration of the device on the controlled side becomes complicated.

The present invention solves the above-mentioned problems, and its purpose is to simplify the configuration of a device on the controlled side that is necessary for confirming the reception of control information.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a remote control method for remotely controlling a controlled device connected to a control device via a transmission path, in which the control device side sends control information to the transmission path. a control information transmitter that receives the return control information sent from the controlled device side via the transmission path; and a return information receiver that receives the return control information received by the return information receiver and the control information. a comparison unit that compares the control information sent from the transmission unit, and a control information reception unit that receives the control information sent from the control information transmission unit via the transmission path on the controlled device side; , and a control information return section that sends the control information received by the control information reception section to the return information reception section via the transmission path as return control information, and based on the comparison result of the comparison section, the control information is The reception is confirmed.

[Effect]

The control information from the control information sending unit on the control side is added to the control information receiving unit on the controlled side via the transmission path, and the control information return unit on the controlled side returns the control information received by the control information receiving unit and performs control. The information is added as is to the return information receiving unit on the control side. The comparison section on the control side compares the return control information received by the return information reception section and the control information sent out by the control information transmission section.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the invention.

The control device 100 and the controlled device 200 are connected by a transmission path 1, and the control device 100 has a control information transmitter 2.
．． A return information receiving section 5 and a comparison section 6 are provided, and the controlled device 200 is provided with a control information receiving section 3 and a control information return section 4.

Transmission path 1 transmits control information and return control information.

The control information transmitting section 2 transmits control information added from a control section (not shown) to the transmission path 1.

The control information receiving unit 3 receives control information from the transmission path 1,
Output. Control ln output from control information receiving section 3
Each part of the controlled device is controlled by the information. The control information return unit 4 sends the control information received by the control information receiver 3 back to the transmission path 1 as return control information. The return information receiving section 5 receives return control information from the transmission path 1. The comparator 6 stores the control information sent by the control information transmitter 2, and compares this with the return control information received by the return information receiver 5. If the two match, the transmission is successful. Assuming that the process has been completed, a reception (S confirmation signal) is added to the control unit.

FIG. 2 is a flowchart showing an example of the main operation procedure of the remote control method, and the operation will be explained below with reference to the same figure.

First, the control information transmitter 2 inputs control information (operation step S1) and sends the control information to the transmission path 1 (operation step 32). The control information sent to the transmission path 1 is received by the control information receiving section 3, and the control information receiving section 3 outputs the received control information (operation procedure 33). Next, the control information return section 4 sends the control information received by the control information reception section 3 to the transmission path 1 again as return control information (operation procedure S
4). The return control information sent to the transmission path 1 is received by the return information receiving section 5 (operation procedure S5). The control information sent by the control information transmitter 2 in the operation procedure S2 is stored in the memory (B in the figure) in the comparator 6, and is compared with the return control information received by the return information receiver 5 in the operation step S5. - They are compared (operation step S6), and if they match, it is assumed that the transmission has been completed normally and a reception confirmation signal is output (operation step S7); if they do not match, the process returns to operation step S2 and retransmission is performed.

〔Effect of the invention〕

As explained above, in the present invention, the control information received by the controlled side is returned to the control side as is, and the control side performs comparison and verification to confirm whether or not the transmission has been completed normally. Since there is no need to provide means for comparison and verification on the controlled side as in the conventional example, there is an effect that the device on the controlled side can be simplified and miniaturized.
