Abstract

PURPOSE:To omit a runaway preventing circuit by restarting each circuit of a remote operating unit after a control circuit is reset when this control circuit detects the abnormality. CONSTITUTION:If the runaway occurs at a microcomputer set in the control circuit of a remote operating unit 9 or 10 during the boring, a remote operating unit runaway detecting circuit 24 detects the incapability of reception of an answer signal to decide the runaway of the unit 9 or 10 and transmits this information to a control circuit 23. The circuit 23 turns off a remote operating unit power supply circuit 18 to stop supply of the power to the units 9 and 10. Then the circuit 18 is turned on after a prescribed time for supply of the power to the units 9 and 10. A power-on resetting circuit is actuated with both units 9 and 10 according to the ON/OFF of the power supply of the units 9 and 10 respectively. A reset signal is supplied too a control circuit and the microcomputer of the control circuit is initialized to be reset to a normal state.

The remote controller 9 or 10 is operated to monitor images from the surveillance camera 1 or 2 on the monitor television 4 or 5. At this time, the main controller 8 sends and receives data to and from the remote controller 9 or 1o, and according to this data, the surveillance camera 1,
2 and sends the video signal from the camera to the monitor television 4 or S. That is, between the main controller 8 and the remote controller 9 or 10, the main controller 8 is used as the main station,
The remote controller 9 or 1Q is used as a slave station to constantly transmit and receive data using a polling method, and in response to a timing signal from the main controller 8, the remote controller 9 or 10
Operation data is sent back as a response signal. If runaway occurs in the microcomputer in the control circuit 28 of the remote controllers 9, 1o during the polling due to electrical noise or electrostatic discharge, the main controller transmits the timing signal to the remote controller. Even if the signal is sent to the controllers 9 and 10, the response signal cannot be obtained from the remote controller. The remote controller runaway detection circuit 24 in the main controller detects that the above-mentioned response signal cannot be received, determines that the remote controller has runaway, and notifies the control circuit 23 in the main controller, The control circuit 23 turns off the remote controller power supply circuit 18 in the main controller, stops supplying power to the remote controllers 9 and 10, and then restarts the remote controller power supply after a certain period of time has elapsed. The circuit (FIG. 3, 18) is turned on to supply power to the remote controller again. The remote controller is configured to turn on and off the power supplied as described above.
As a result, the power-on reset circuit (Figure 3, 27) is activated, a reset signal is input to the control circuit 28, the microcomputer in the control circuit 28 is also initialized, the runaway is stopped, and the normal operating state is returned. . Further, when the microcomputer in the control circuit 23 of the main controller 8 goes out of control, the runaway prevention circuit 26 detects the runaway of the microcomputer, a reset signal is input to the control circuit 23, and the microcomputer runs out of control. It is initialized, the runaway stops, and the normal operating state is restored.
