[0008] The present invention is realized through the following technical solutions: A detection device for the safety interlock device of a quick-opening container and a container control cabinet, comprising a power supply circuit, a main controller, a liquid crystal display screen, a main pressure adjustment module, an auxiliary pressure adjustment module, a pressure transmitter signal simulation module, a zero-pressure controller signal simulation module, a storage module and an air exhaust.

The air exhaust is respectively connected to the main pressure adjustment module and the auxiliary pressure adjustment module; A pressure sensor is also arranged on the air exhaust through an air path, and the pressure sensor is connected to the main controller.

[0009] The air exhaust is used to connect each air pressure module (DC air pump, pressure sensor, micro air pump, etc.) inside the detection device.

[0010] The liquid crystal display screen is connected to the main controller and serves as a user interface for setting test parameters, starting tests and viewing results.

[0011] The power supply circuit provides stable and reliable power supply for the detection device to ensure the normal operation of each component.

[0012] The main controller controls the working processes of each module, processes data and coordinates the overall operation.

[0013] The main pressure adjustment module is used to generate and stably convey air pressure so that the detection device can test the safety interlock device.

[0014] The auxiliary pressure adjustment module is used to finely adjust the air pressure in the air exhaust to ensure the test accuracy.

[0015] The pressure transmitter signal simulation module is used to simulate the pressure transmitter signal to verify the response of the container control cabinet when the pressure changes.

Set the analog range, zero-pressure control default state (there are two states for the zero-pressure control default state: "normally open" and "normally closed".
