Referring to FIG. 3, the imaging unit checking step (S1) first analyzes an image state of a camera and control lines of a motor circuit and a receiver (S11) to determine whether an abnormal state occurs (S12).

 At this time, if an abnormal state occurs, the image line state, the image level, the line short circuit / disconnection is determined (S13), and the image and line abnormal information are transmitted from the receiver to the field control unit (S14).

The field control unit analyzes an image state based on the received information (S15) and determines whether a loss occurs (S16).

If a loss occurs, it is determined whether an alarm is generated and the alarm history is analyzed (S17). If an alarm corresponding to an image loss occurs (S18), a camera failure alarm is issued (S19) and a video line failure is detected. If an alarm occurs, the video line failure alarm is issued (S20).

In addition, the field control device analyzes the data received from the receiver (S21) and determines whether an alarm has occurred (S22) or whether a serial communication reception level loss has occurred (S23).

If an alarm occurs, the alarm history is analyzed (S24), the type of alarm is determined (S26), and if it is a control line alarm, a camera control line alarm is issued (S27), and if a serial communication alarm, a receiver communication alarm is issued. (S25).

This video loss detection and alarm generation is because the NTSC video signal standard transmits the video signal with the signal level of 1V _pp . When the disconnection of the video cable occurs, the resistance of the line becomes infinite (∞). Can be.

In addition, when a short circuit occurs, the resistance of the line is displayed as 0 Ω, so that an image loss due to a short circuit can be detected.

When the loss of the video signal due to the disconnection or short circuit occurs, the field control unit collects the details of the corresponding alarms and informs the administrator of the alarms through pop-up alarms and audible alarms through the integrated management server, and the server data. The alarm history is saved in the base so that the administrator can respond to the alarm.

In addition, the camera, the rotary motor, and the receiver can be checked in real time by transmitting and receiving a periodic status check signal between the receiver and the field control unit to check the driving state of the receiver due to loss of the corresponding check signal and disconnection of the line. .

If an abnormal state occurs in the detection sensor, the state is determined (S33), and the abnormality information of the detection sensor is transmitted to the field control unit by the alarm receiving panel (S34).

The field control unit analyzes the data received from the alarm receiver (S35) and determines whether an alarm has occurred (S36) and whether a loss has occurred with respect to the reception level of the serial communication (S39).

If an alarm occurs, the details are analyzed (S37) to issue a fault alarm of the detection sensor (S38), and if a loss occurs, an alarm receiver alarm is issued (S40).

The self-checking function of the alarm receiving panel can be connected to various sensors according to the operation method of the infrared or thermal sensor because the alarm receiving panel can receive the voltage and resistance contacts and output the no-power contact. The periodic status check signal of the control unit allows the real-time check of the operating state of the alarm receiver.

The failure of the alarm receiving panel is determined by receiving a signal for a predetermined time, and when there is no response according to the status request or receives a signal that is not a normal status check response, it is determined that the alarm receiving panel is a failure, and when it is determined to be a failure, it pops up to the administrator. And sends an alarm via an audible alarm.
