At present, a compressed air foam system applied to a converter station and a conveying pipe network thereof are relatively complex, and a linkage control system is generally adopted for automatic fire extinguishing. The application of the linkage control system can reduce the workload of operation and maintenance personnel and improve the automation level of the fire extinguishing system. However, as the situation is complicated when a fire disaster occurs, the malfunction of the coordinated control system may be caused by the false fire alarm signal of the fire alarm host or the signal feedback error of the local fire-fighting equipment, which may cause the expansion of the accident. In addition, the linkage control system controller or the outlet relay and other faults can lead to the situation of a fire, and the fire cannot be timely started to extinguish, so that the fire can be expanded.

Detailed Description
The following description will specifically explain the present invention with reference to the drawings and examples.
The embodiment of the invention provides a linkage control method for a compressed air foam system, which comprises the following steps as shown in figure 1:
receiving a fire alarm signal, and entering a fire extinguishing process after setting time delay; the misoperation of the linkage system caused by the false alarm of the fire alarm host is prevented.
Detecting whether the converter transformer is in a maintenance state;
and locking the starting of the compressed air foam system according to the position state of the circuit breaker corresponding to the converter transformer in the fire.
The breaker position state is a single breaker position state or a combination of multiple breaker position states.
When the position state of the circuit breaker is in a separated position, the compressed air foam system is allowed to be started; and when the position state of the circuit breaker is in a closed position, the compressed air foam system is prohibited from being started.
The position state of the circuit breaker is obtained by connecting the position normally closed nodes of the middle circuit breaker and the side circuit breaker in series.
The compressed air foam system-initiated latch modes include a software latch and a hardware latch.
A control host machine in the compressed air foam system collects position division signals of circuit breakers at a pole I high end, a pole I low end, a pole II high end and a pole II low end to serve as software logic locking signals. Because the circuit breaker adopts 3/2 wiring mode, the software locking refers to judging the position state of the circuit breaker in the software logic of the linkage control system.
The hardware locking refers to the connection of a circuit breaker position node signal in a hardware outlet loop of the compressed air foam system. The partition selection valve in the CAFS generating device equipment room of the compressed air foam system controls a position division node of a series circuit breaker in a loop, if the circuit breaker is not divided, the partition selection valve cannot be opened, and foam cannot be sprayed to the tail end of a pipeline. And the fire extinguishing process is ensured not to be sprayed by mistake in hardware.
The converter transformer in the maintenance state is locked by putting the maintenance pressing plate into the converter transformer, so that the fire alarm signal is prevented from being triggered by mistake in the maintenance process.
The compressed air foam system is of a star-shaped structure and is divided into two types of devices, namely a linkage control main machine and a linkage control sub machine. The host computer is responsible for linkage logic, and the submachine is responsible for interacting with the on-site fire-fighting equipment.
The linkage control host and the linkage control sub machine in the compressed air foam system are in redundant configuration and are powered by an external redundant power supply, and a communication link between the linkage control host and the linkage control sub machine is in redundant configuration. The power supply of the linkage control host machine and the linkage control sub machine is supplied by a station fire power supply and a UPS power supply, and the power supply reliability of the linkage control system is guaranteed.
The above embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and any modifications made on the basis of the technical scheme according to the technical idea of the present invention fall within the protection scope of the present invention.
