As shown in Figure 1, a kind of traffic lights Huang dodges controller, the heartbeat bag data issued including receiving external signal machine
Electrical power carrier circuit 100, heartbeat bag data is obtained, when heartbeat has not been obtained in prefixed time interval according to prefixed time interval
When bag data, the governor circuit 200 of output control signal and the switching circuit 300 according to control signal output alarm signal are alert
Show signal for controlling external amber light flashing operating circuit work；
Electrical power carrier circuit 100 is connect with governor circuit 200, and governor circuit 200 is connect with switching circuit 300, switch electricity
Road 300 is connect with external amber light flashing operating circuit.
Electrical power carrier circuit 100 receives the heartbeat bag data that external signal machine issues.Power carrier is that electric system is peculiar
Communication mode, power line communication technology is to realize data transmitting and letter using existing low-voltage network as transmission medium
Cease a kind of means of exchange.When power application line communication mode sends data, transmitter first modulates data on a high frequency and carries
On wave, it is coupled on power line using after power amplification by coupling circuit.Signal band peak-to-peak value voltage is usually no more than
10V, therefore adverse effect will not be caused to power circuit.The difference of power line carrier communication and general aerial line carrier communication
It is that available spectral range can only open limited channel from 8kHz-500kHz in same power grid, such as each half-duplex channel needs
Standard bands 4kHz is occupied, then the frequency band cannot be reused, and otherwise will generate serious cross-talk.Therefore general power line carries
Wave device is all made of single channel single-side belt system, every channel dual seizure 2 × 4kHz bandwidth, in total 61 circuits.If necessary
More circuits is opened, then must take the quarantine measures for installing power grid high-frequency segmentation filter additional.
Heartbeat packet is that the command word of oneself definition of other side oneself state is periodically notified between client and server,
It is sent according to certain time interval, heartbeat is similar to, so being called heartbeat packet.The data that send and receive in network all make
It is realized with SOCKET (socket), but if this socket is already off, with regard to one when that sends data and receives data
It surely can be problematic.Heartbeat packet is exactly that client regularly sends simple information to server end, is transmitted every few minutes one admittedly
Information is determined to server end, and server end replys a fix information after receiving, if do not received in server end a few minutes
Client-side information then regards client disconnection.For example some communication softwares do not use for a long time, to know that its state is online
Or heartbeat packet is just needed offline, packet receiving of periodically giving out a contract for a project.
Governor circuit 200 obtains the received heartbeat bag data of electrical power carrier circuit 100 according to prefixed time interval, when default
When heartbeat bag data having not been obtained in time interval, output control signal.Such as it can be real by the timer in governor circuit
Whether existing prefixed time interval detection electrical power carrier circuit, which has, sends heartbeat bag data, when having not been obtained within a preset time interval
When heartbeat bag data, output control signal.Specifically, if upper one detects heartbeat bag data in 5 seconds, and in next 5 seconds
It is not received by heartbeat bag data, then exports control signal.
The control signal that switching circuit 300 is exported according to governor circuit 200, output is for controlling external amber light flashing work
The alarm signal of circuit work.Such as switching circuit receive governor circuit output control signal when, such as high level letter
Number, closing the switch in trigger switch circuit, switching circuit exports alarm signal, and external amber light flashing operating circuit is receiving
When the alarm signal, amber light flashing function is realized.

It is connect with external amber light flashing operating circuit, electrical power carrier circuit 100 receives the heartbeat bag data that external signal machine issues, master control
Circuit 200 obtains heartbeat bag data according to prefixed time interval, defeated when heartbeat bag data having not been obtained within a preset time interval
Signal, the warning that switching circuit 300 works according to the output of control signal for controlling external amber light flashing operating circuit are controlled out
Signal realizes the alarm function of amber light flashing.The traffic lights Huang dodges controller and passes through electrical power carrier circuit and external signal
Machine communication obtains the heartbeat bag data of semaphore, and governor circuit obtains heartbeat bag data according to prefixed time interval, when default
Between in interval when heartbeat bag data has not been obtained, there is failure in characterization Traffic signal control, in this case, master control electricity
Road outputs control signals to switching circuit, and switching circuit exports alarm signal according to control signal, which can control
External amber light flashing operating circuit realizes amber light flashing, and traffic lights Huang may be implemented in this way and dodge independent control, without relying on
