Abstract

PURPOSE:To solve the shortage of the current capacity of a power source by outputting an operation indication signal to an equipment control part with delaying a set time only when a simultaneous operation indication signal is inputted from a communication control part. CONSTITUTION:When the simultaneous operation indication signal transmitted to all terminal equipment 4 according to monitor information is inputted from the communication control part 6, a delay setting part 11 transmits the operation indication signal to the equipment control part 8 with delaying the individually set time by a dip switch and, in other cases, it directly transmits the signal. In case of outputting the simultaneous operation indication signal from a remote controller 1 to all terminal equipment 4 according to the monitor information, operational actions are executed delaying by the time set in the delay setting part 11 of each terminal equipment interface 2. Thus, the shortness of the power source capacity can be solved by altering the individual delay set time even if plural number of terminal equipments where high current flows at the time of beginning the operation are connected.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a method for connecting a remote control device and a bus-type signal line.
The present invention relates to a terminal equipment interface that controls and monitors the operation and stopping of terminal equipment.

A conventional technical remote control system has a configuration as shown in FIG. Remote control device 1, terminal device 2;) interface 2
are connected by a bus-type signal line 3. The terminal device 4 operates and stops based on the operation and stop control output from the terminal device interface 2, and outputs the status as a monitor signal. Terminal <1 HH interface 2 is
It is composed of circuit blocks as shown in FIG. The transmitter/receiver circuit 5 modulates and demodulates the signal. Communication control unit 6
is remote 1; 'A operation of terminal equipment 4 between control device 1,
Stop device j] Sends and receives command and monitor information. The self-address setting unit 7 sets a self-address for the communication control unit 6 to exchange packets of information with the remote control device 1. The device control unit 8 is operated by the communication control unit 6,
When a stop instruction signal is input, the terminal device 4 is operated or stopped via the control output circuit 9, and when the operation or stop state of the terminal device 4 is changed manually from the monitor input circuit 1o, the terminal device 4 is operated or stopped via the communication control unit 6. and transmits monitor information to remote control device ii: 1.

Problems to be Solved by the Invention However, in the above-mentioned J'' configuration, when a simultaneous operation instruction is issued from the remote control device by broadcast, the same 11
All the terminal devices are operating, and due to insufficient power supply capacity, a large current flows at the start of operation.''
The problem was that multiple three devices could not be connected.

The present invention solves these conventional problems, and
The second objective is to enable simultaneous operation instruction signals from all terminals through communication.

Means for Solving the Problems In order to solve the above problems, the terminal equipment interface of the present invention allows the machine Hg control unit to delay the machine operation by a set time only when a simultaneous operation instruction signal is manually input from the communication control unit. This is provided with a delay setting section that outputs an instruction signal.

Effect of the present invention With the above-described configuration, even if a plurality of terminal devices through which a large current flows are connected at the start of operation and a simultaneous operation instruction is issued by broadcasting from the speed 1gA control device, the individual terminals (7
Since the operation of 1/+h is delayed by the delay time set in each terminal device interface, it is possible to prevent all terminal devices from entering the operation start operation at the same time.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 is a circuit block diagram of the terminal device interface 2. As shown in FIG. , l, IIl Control of operation and stop of terminal equipment 4 is as follows:
Output from control output circuit 9, status is from monitor input circuit 1
Enter 0. The communication control unit 6 exchanges packets with the remote control device 1 according to a predetermined communication procedure, and exchanges commands for operating and stopping the terminal device 4 and monitor information. The self-address setting section 7 consists of an 8-bit dip switch, and the d-signal control section 6 connects the signal line 3
Set up a self-address for exchanging packets of information via. The transmitting/receiving circuit 5 modulates the communication packet from the communication control unit 6 to generate a signal! Send to l'3A 3 J-,
The signal of the 1-f return line 3-1- is demodulated and output to the communication control section 6.

When a simultaneous operation instruction signal transmitted to all terminal devices by broadcasting is manually transmitted from the communication control section 6, the delay setting section 11 causes the device control section 8 to delay the operation by a time set individually using a dip switch. Convey instructional signals, otherwise communicate immediately.

In the above configuration, χ=
11. When a simultaneous operation instruction signal is output by broadcasting, the operation operation is delayed by the time set in the delay setting section of each terminal device interface, so when starting operation, multiple terminal devices that flow a large current can be connected. Even in such a case, the problem of insufficient power supply capacity can be solved by changing the individual delay setting times.

According to the terminal device interface of the present invention, as described in ``Effects of the Invention'' 2, when the simultaneous operation instruction is issued by broadcast, the operation of the terminal devices is delayed by the time set in the delay setting section, so that there is a large delay at the start of operation. This solves the problem of insufficient current capacity of the power supply when multiple terminal devices that carry current are connected.
