Multi-position fire-fighting detector function test system

The utility model discloses a multi-position fire-fighting detector function test system, which belongs to the technical field of detector function test and comprises a test skip car, a car frame is arranged on the test skip car, a main controller and a tray are arranged on the car frame, and a tooling plate and a relay plate are arranged on the tray. A cement resistor with a fire extinguisher starting simulation function is arranged between the relay plate and the tool plate, a CAN network connected in parallel is arranged on the cement resistor, and the cement resistor and one end of the CAN network are connected in series with the relay plate. By introducing a double-layer CAN communication network architecture, the number of CAN bus nodes is increased, and test stations are doubled; through the introduced WiFi module, communication between the main controller and the server is carried out by using a Wi-Fi network, and remote monitoring, control and data interaction are realized.
