[0047]Example 1 An online detection device for a fire extinguishing system

[0048] This embodiment includes a casing and a detection circuit arranged in the casing. Such as figure 2 Shown is the schematic diagram of the external structure of this embodiment, as image 3 Shown is a circuit diagram of the detection circuit of this embodiment.

[0049] The detection circuit includes a power supply, electric squib detection circuit, flame sensor detection and analog circuit and actuator detection circuit, wherein the output terminals of the power supply are respectively connected to the power input of the electric squib detection circuit, flame sensor detection and analog circuit, and actuator detection circuit end. Such as image 3 As shown, the squib detection circuit includes the first squib indicator light XD 1 And the second electric squib indicator light XD 2 , the first electric squib detection signal input end of the electric squib detection circuit is connected to...

Embodiment 2

[0054] Embodiment 2 An online detection method of a fire extinguishing system

[0055] This embodiment adopts embodiment to realize, carry out according to the following sequence of steps:

[0056] 1. Wiring

[0057] Such as Figure 4 As shown, four channels of flame sensor signals and two channels of electric squib signals are drawn between the control box LKF1 of the fire extinguishing system and the first socket CZ1, and the throttle flameout signal and wind stop signal are drawn from between the control box LKF1 and the third socket CZ3 Signal;

[0058] Disconnect the two electric squibs of the fire extinguishing system and replace them with two electric squib detection cables. The signal input ends are connected in one-to-one correspondence, and the other ends of the two electric squib detection cables are connected to the two electric squib signals on the one hand, and connected to the throttle flameout signal and wind stop signal on the other hand. ;

Abstract

The invention discloses a fire extinguishing system on-line detection device which comprises a power supply, an electric detonator detection circuit, a flame sensor detection and simulation circuit and an execution mechanism detection circuit. The output end of the power supply is respectively connected with the power supply input ends of the electric detonator detection circuit, the flame sensor detection and simulation circuit and the execution mechanism detection circuit. The invention further discloses a fire extinguishing system online detection method. A three-way socket is adopted to take out a flame sensor signal and an actuating mechanism action signal online, and through signal processing and standard comparison, whether burning, pressing control and other processes work normally or not is detected on line, so that whether a fire extinguishing system breaks down or not is judged. According to the invention, faults of all components and a control center of the artillery fire extinguishing system can be reliably detected, the defects of online detection means of the artillery fire extinguishing system are made up, and the method plays an important role in effectively maintaining the integrity of an artillery. The invention belongs to the technical field of artillery protection devices.

Description

technical field [0001] The invention belongs to the technical field of artillery protection devices and is used for the detection of artillery fire extinguishing systems, in particular to an online detection device and detection method for fire extinguishing systems. Background technique [0002] At present, most of the wheeled and tracked self-propelled artillery developed by our army are equipped with an automatic fire extinguishing system. This fire extinguishing system includes sensing elements-flame sensors, control centers, and actuators-electrically controlled fire extinguishers and air intake and exhaust control systems. Such as figure 1 As shown, it is a connection schematic diagram of the main components of the existing artillery fire extinguishing system. The fire extinguishing control box LKF1 is the core of the fire extinguishing system. The fire extinguishing control box LKF1 is respectively connected to the flame sensor 1 and the fire extinguishing bottle 2 th...
