The utility model is achieved in that it has a boxcar and air hose, its special character is: control circuit, linear motion device and the air compression plant that is connected with linear motion device are installed in boxcar, described air compression plant by connecting line respectively be installed in boxcar in pressure transducer, gas bleed valve and air hose be communicated with, described control circuit is connected with pressure transducer with linear motion device respectively, is used for controlling the linear motion device duty.
Above-mentioned air hose line style differential fire detector, described linear motion device be by motor, be installed in the slide block on the motor output shaft, the guide rail that is located in the boxcar constitutes, and slide block is connected with air compression plant.
Above-mentioned air hose line style differential fire detector, described air compression plant is copper corrugated tube.
Above-mentioned air hose line style differential fire detector, described pressure transducer is a micro-pressure sensor, utilizes the characteristics of the continuous subtle change of its nothing that has machinery contact, energy detected pressures, and intelligent the processing is achieved.
The full-closed structure that the utility model adopts malleation to keep has and leaks or when losing when being installed in the on-the-spot air hose of detection, and the pressure transducer in boxcar detects the air hose internal pressure, quotes and leak or lose fault automatically.When automatic simulation alarm detection, the air compression plant action is produced continue the positive air pressure that raises by control circuit, the air expansion that produces when simulated fire takes place is realized simulation alarm detection function automatically.This detector can be realized Based Intelligent Control by single-chip microcomputer, reaches automatic leak detection, reports to the police automatically and simulates the warning purpose.
