The fire detector is a fire-fighting automatic alarm system, and is a device for detecting fire on site and monitoring whether fire occurs in environment.

The BIDS detector and the lithium battery composite fire detector are arranged in a battery box of the electric automobile, and when a fire occurs, the fire suppression device of the lithium battery box can be automatically started to extinguish and suppress the fire.

The composite alarm detector detects environmental parameters such as a fire detector, a vehicle battery detector, a BIDS detector and the like through a plurality of sensors, wherein the fire detector senses whether fire occurs in a monitored environment or not through detecting parameters such as temperature, gas, smoke, air pressure and the like, and the sensing speed and the sensing accuracy of the fire detector to the fire influence rescue work after the fire occurs, so that the fire detector needs to carry out quality detection (delivery detection) before delivery, and the fire detector is ensured to meet delivery standards.

At present, in the factory detection process of the fire detector, the test fixture is single, only one parameter can be tested at a time, and in the related art, when one fire detector is subjected to the out-of-field detection, the fire detector is sequentially sent into a smoke box, a CO calibration box, a temperature box, a VOC release box and a gas pressure device so as to respectively detect whether each sensor in the fire detector operates normally. However, in practical application, the fire detector needs to detect multiple data at the same time, and the fire detector and the controller connected with the fire detector are all based on the combination of multiple data to comprehensively judge whether a fire occurs, and send out an alarm and control the fire suppression device based on the judgment result. Obviously, the above detection method can only detect a single sensor in the fire detector, and the detection result of the single sensor cannot accurately reflect the actual parameters of the fire detector, for example, when the environmental parameters meet more than two trigger conditions, it cannot be determined whether the fire detector can normally alarm, so that the single parameter test cannot meet the effective and accurate test requirements.

In order to solve the technical problems described above, the embodiments of the present disclosure provide a multifunctional test system, which is applied to the detection of a fire detector, and the system can simulate the actual environment when a fire disaster or a fire disaster occurs, and can quantitatively regulate and control to simulate and reproduce parameter data in different fire states, thereby detecting whether the fire detector can normally work in various fire states, and improving the accuracy and effectiveness of the test of the fire detector.

In an embodiment of the present disclosure, referring to fig. 1 and 5, a multifunctional test system includes a test case, an environment simulation module, an environment verification module, and a controller module.

To ensure accurate testing of fire detectors, the system should meet at least the following two requirements when simulating a fire environment: on the one hand, the change rate of each parameter corresponds to the change condition of the real fire disaster, for example, the temperature rising speed, the air pressure rising speed, the CO concentration rising speed, the smoke concentration rising speed and the VOC concentration rising speed should be kept coordinated and unified; on the other hand, the instantaneous values of the parameters correspond to the data values of different stages of a real fire, for example, when a fire is about to occur, the parameters should correspond one by one; when a fire occurs, the parameters should also be in one-to-one correspondence; the parameters should also be in one-to-one correspondence when the fire expands.
