[0027] The detection system includes an acquisition module, a time module, a judgment module, a control module and an alarm module. The acquisition module is electrically connected to the detection component 4 and is used to collect and analyze detection data. The time module is used for timing.

The control module is electrically connected to the clamping component 2, the combustion component 3, the detection component 4 and the temperature and gas control component 5 and is used to control the operation. The alarm module is used for alarm prompts.
[0028] Working principle: The staff places the sample to be tested between the clamp block 261 and the movable block 263, turns the knob 262 to fix the sample to be tested, then turns the knob 1 to drive the chuck 26 to rotate, adjusts the chuck 26 to a horizontal or vertical state, and then manually turns the knob 33 to drive the connecting seat 35 and the flamethrower 36 to rotate, adjusts the angle pointed by the pointer on the connecting seat 35 to the required test angle, closes the detection box 1, and inputs the detection parameters on the control component 7.
[0029] The staff starts the detection box 1, and the flamethrower 36 is ignited. The acquisition module collects the images captured by the camera 45 and the flame temperature identified by the thermal imaging camera 41. The flame size is adjusted by controlling the electric control valve 55 on the pipeline connecting the combustible gas tank 53 and the flamethrower 36. After the judgment module determines that the flame temperature and flame height are stable, the control module controls the cylinder to drive the horizontal moving seat 22 and the vertical moving seat 23 to move horizontally and vertically, driving the sample to be tested on the chuck 26 to contact and separate with the flame. At the same time, the time module records the actual contact, separation and combustion of the sample to be tested with the flame, and conducts a vertical combustion test or a horizontal combustion test.
[0030] It should be noted that the acquisition module is provided with the temperature range for flame temperature stability, flame height range, flame contact and separation time with the sample to be tested, which are set by the staff with reference to the flame retardant test performance standard. Whether the sample is burning or not is determined by the image captured by the acquisition module camera 45 and fed back to the judgment module for judgment.
[0031] In the vertical combustion test or the horizontal combustion test, the acquisition module uses the temperature sensor 42 to measure the internal temperature of the detection box 1, the oxygen concentration detector 43 to measure the oxygen concentration inside the detection box 1, the nitrogen concentration detector 44 to measure the nitrogen concentration inside the detection box 1, the camera 45 to shoot the combustion conditions of the sample, and the pressure gauge 46 to measure the pressure change inside the detection box 1.
[0032] Case 1: the control motor 61 drives the baffle door 62 to be placed in the placement slot, that is, the smoke exhaust port can exhaust normally, and the temperature and gas control component 5 is controlled not to pass gas into the detection box 1: it is a normal test state.
[0033] Case 2: The control motor 61 drives the baffle door 62 to be in the placement slot, and the temperature and gas control component 5 is controlled to pass gas into the inside of the test box 1, but the refrigerator is not running: the oxygen and nitrogen concentrations of the gas mixing chamber 56 are set in the program to ensure that they are close to the actual air composition and can simulate the flame retardant performance in flowing air; if the refrigerator is controlled to run, it can simulate the flame retardant performance of the test sample in an environment with air flow, constant temperature or cooling, and at this time, it can also avoid damage to various components caused by continuous high temperature inside the test box 1.
[0034] Case three: controlling the motor 61 to drive the baffle door 62 to seal the smoke exhaust port, and not controlling the temperature and air control component 5 to pass gas into the detection box 1: it can simulate the oxygen index test. Specifically, when the camera 45 captures that the flame of the burning sample is extinguished or no longer reignites, the oxygen concentration measured by the oxygen concentration detector 43 is the minimum oxygen concentration at which the test sample can maintain a burning state.
[0035] Case 4: The control motor 61 drives the baffle door 62 to seal the smoke outlet, and controls the temperature and gas control component 5 to pass gas into the detection box 1, but the refrigerator is not running: the oxygen and nitrogen concentrations of the gas mixing chamber 56 are set in the program, and the oxygen and nitrogen concentrations are adjusted in combination with the oxygen concentration and nitrogen concentration inside the detection box 1 to ensure that the oxygen content inside the detection box 1 is constant, and can simulate the maximum environmental pressure for normal combustion of the test sample when the oxygen concentration is constant; when the refrigerator is running, it can simulate the maximum environmental pressure for normal combustion of the test sample when the temperature and oxygen concentration are constant. Specifically, when the camera 45 captures that the flame of the burning sample to be tested is extinguished or no longer reignites, the pressure value displayed on the pressure gauge 46 is the maximum environmental pressure at which the test sample can burn normally.
[0036] After the flame retardant performance test is completed, for samples judged to have a high flame retardant performance grade, or samples whose thermal deformation capacity to be tested needs to be judged separately, the samples can be heated to a set temperature, and then the control module controls the cylinder to drive the lateral moving seat 22 and the vertical moving seat 23 to move to the lower right side of the inside of the detection box 1. At this time, the lateral moving seat 22 drives the rotating plate 27 to rotate clockwise around the hinge, so that the left side of the rotating plate 27 can contact the sample to be tested, and the sample to be tested is deformed under the action of the force. The acquisition module then captures the picture taken by the camera 45 to identify the deformation of the sample to be tested, so that the deformation resistance of the sample to be tested at different temperatures can be judged, which can ensure the safety of product use and avoid the product being damaged, deformed, or broken due to poor deformation resistance in an environment with high temperature or flame, causing damage to the internal components of the product. At the same time, the rotating plate 27 rotating around the hinge can also prevent the burning waste from sticking to the bottom of the detection box 1, and avoid the bottom components of the detection box 1 being damaged due to high temperature after the sample with poor flame retardant performance falls.
[0037] It should be noted that the judgment module is also provided with the maximum temperature limit and the maximum pressure limit inside the detection box 1. When the acquisition module detects that the temperature inside the detection box 1 measured by the temperature sensor 42 is higher than the temperature limit or the pressure inside the detection box 1 measured by the pressure gauge 46 is higher than the pressure limit, feedback is sent to the alarm module to issue an alarm prompt to avoid safety hazards. At the same time, the control module controls the motor 61 to drive the baffle door 62 to be in the placement slot, and at the same time controls the electric control valve 55, refrigerator, and exhaust fan 64 on the pipeline connecting the nitrogen tank 52 and the gas mixing chamber 56 to open, so as to quickly reduce the internal temperature and oxygen concentration of the detection box 1 and improve the safety of the use of the detection equipment.
