AI Technical Summary

Technical Problem

Conventional testing of differential distributed sensors is cumbersome and requires multiple steps due to the need to reconnect test equipment and switch air passages for each test, involving a syringe and manometer, which complicates the process.

Method used

A differential distributed sensor system that includes an air pipe connection part, an air injection means, a pressure sensor, and a determination processing unit, allowing for a single test setup that detects pressure changes to determine test results without repeated reconnections or air injection for each test step.

Benefits of technology

The system simplifies the testing process by reducing the number of steps required, as it estimates the air pipe length and pressure reduction range based on pressure sensor output, enabling easy and efficient testing of the sensor.

Abstract

To provide a differential distributed type sensor that allows for easy testing. [Solution] A differential distributed type detector 10 that detects a fire by detecting a pressure rise in an air pipe 11 laid in a protected area, comprising an air pipe connection part 13 to which the air pipe 11 is connected, an air injection means 4 for injecting air into the air pipe 13, a pressure sensor 2 provided between the air pipe 11 and the air pipe connection part 13 for detecting the pressure in the air pipe 11, and a determination processing unit 3 that determines the test result of the detector based on the output value of the pressure sensor 2, wherein the detector can be tested using the air injection means 4, the pressure sensor 2 and the determination processing unit 3.
