As shown in figure 3, warning part 9 is coupled to time delay portion 8 with reception delay signal and is entered with time delay in response to time delayed signal
Row warning, warning part 9 are sounding alarm.Warning part 9 includes that the timing closing of time relay KT instantaneously disconnects normally opened contact
KT-1 and buzzer SP, the timing closing of time relay KT instantaneously disconnect the power supply that normally opened contact KT-1 is series at buzzer SP
Loop.
It is coupled with receiver module 11 for receiving infrared-ray detection signal and in response to infrared detection signal to count
Infrared ray separates the impulse scaler of number of times.The electric impulse counter of preferred model CSK4-YKW of impulse scaler.
The course of work is as follows：
When someone is operated near the cabinet 1 of power distribution cabinet, as human detection unit 6 is able to detect that what human body sent
Infra-red radiation, therefore export the input of the human detection signal to control unit 7 of high level.At this moment no matter cabinet door 2 either with or without
Shut, i.e., no matter infrared ray whether there is and separated, and control unit 7 all exports the base stage of low level control signal to audion Q1,
End audion Q1, the coil of time relay KT is in power failure state, and its corresponding timing closing instantaneously disconnects normally opened touching
Point KT-1 is off, and cuts off the current supply circuit of buzzer SP, and buzzer SP does not report to the police.
When people leave the cabinet 1 of power distribution cabinet, human detection unit 6 can't detect the infra-red radiation of human body, so as to export
The input of low level human detection signal to control unit 7.
If staff closes cabinet door 2 before leaving, retaining piece 3 is plugged in slot 4, complete due to working as retaining piece 3
After being fully inserted in slot 4, its some it is exposed outside slot 4, and beyond one segment distance of opening of slot 4, so as to
Enough barriers live the infrared ray sent by transmitter module 10, receiver module 11 is received infrared ray and is exported high level
The input of infrared detection signal to control unit 7, makes control unit 7 export low level control signal to audion Q1's
Base stage, ends audion Q1, can be obtained by inference before, and buzzer SP does not sound the alarm.
Conversely, if staff is not turned off cabinet door 2 before cabinet 1 is left, retaining piece 3 is not plugged in slot 4, makes to connect
Receive module 11 to receive the infrared ray that sent by transmitter module 10 and export low level infrared detection signal to controlling
The input of unit processed 7, makes the base stage of the control signal to audion Q1 of the output high level of control unit 7, leads audion Q1
Logical, the coil of time relay KT obtains electric adhesive, initially enters time status, arrives when the time one of setting, time relay KT
Timing closing instantaneously disconnect normally opened contact KT-1 closure, turn on buzzer SP current supply circuit, make buzzer SP send alarm
Sound, to remind staff to return to close cabinet door 2 in time, so that buzzer SP stops alarm.
If during time delay, someone's time relay KT returns, then human detection unit 6 exports high level again
The input of human detection signal to control unit 7, makes control unit 7 export again low level control signal to audion Q1
Base stage, end audion Q1, the coil losing electricity of time relay KT resets, and stops timing, and buzzer SP does not still report to the police.
Wherein, the duration of time delay can be changed by the parameter of regulating time relay KT.
After infrared ray detector unit 5 detects infrared ray to be separated once, which can export a pulse signal to pulse
Enumerator, makes impulse scaler remember a number, so as to obtain the number of times that cabinet door 2 is finally closed, to judge making for cabinet 1 and cabinet door 2
Use the life-span.
Wireless generator is connected with impulse scaler, impulse scaler can be counted by wireless or wire signal
Number of times be transferred to server, then retransmit to handset.
As shown in figure 1, radio transmitting device is coupled to control unit 7 to receive control signal and in response to control signal.
Radio transmitting device is preferably wireless router, and wireless router sends wireless signal by receiving control signal, when which connects
After receiving the control signal of high level, its corresponding wireless signal of output to cloud server then will by cloud server
To handheld terminal, handheld terminal can be mobile phone or panel computer to signal transmission.
The number of times separated by infrared ray can be checked at any time by handheld terminal, to detect number of times that power distribution cabinet is used,
So as to judge the service life of power distribution cabinet, when the number of times separated by infrared ray is excessive, mobile phone can send automatically prompting or
Vibration, changes and maintenance package so as to timely.
