[0030] Embodiment 3: As Figure 5As shown in the figure, on the main control box 6 of the fire resistance detection device for doors and windows glass, there is a touch screen 61. Inside the main control box 6, a processor 62, a multi-channel signal acquisition and processing module 63, a timer 64, a relay module 65, a display module 66, a wireless data transmission module 67 and an acoustic-optic alarm module 68 are integrated.

[0031] During the test: The main control box is driven according to a preset time sequence. First, the pushing cylinder is driven to press the test sample against the outside of the intersection of the detection furnace, and then the opening solenoid valve is driven to open proportionally. After the gas is mixed in the Venturi mixer, it is ignited at the flame burner. After the furnace temperature and furnace pressure sensors detect that the temperature and pressure inside the furnace reach the test threshold, the main control box drives the timer to start timing. During the standard fire resistance duration, the heat flux sensor 56, smoke sensor 57, and deformation displacement sensor continuously collect performance indicators such as the heat insulation, smoke resistance of surface damage, and surface damage deformation of the test sample. If all indicators meet the standard threshold after the timing is completed, the test sample is qualified. If the heat transmission amount, smoke transmission amount of damage, and surface deformation displacement amount exceed the standard, the alarm is driven to sound an alarm, and the data is remotely uploaded to the host computer through the wireless data transmission module. The furnace temperature and pressure thresholds and performance standard index thresholds can be set and adjusted on-site and remotely through the touch screen and wireless data transmission module. During the operation process, the touch screen is used to display the parameters and performance detection signals inside the furnace in real time, and the display content can be switched by touch.
