The working principle and the standard elements are briefly described as follows:

the adaptive push-pull sensor 3 adopted in the embodiment adopts a cylindrical pressure sensor with the model of SBT673 provided by the Guangzhou Cin Sibuto electronic technology company Limited, the output signal of the sensor is an analog signal, resistance strain type conversion is adopted, multi-point stress is adopted, the surface is made of stainless steel, the test and measurement in the temperature environment below 80 ℃ can be met, the rated range is 20Kg-2T, the calibration error is 0.05%, the insulation strength reaches 3500, the hysteresis is less than or equal to 0.05% F.S, the nominal excitation voltage is 5V, and the sensor has the advantages that:

the device can completely meet the measurement of the clamping force of the shear type door of the gate on the technical parameters, the sensitivity and the measurement range of the test of the device cover the requirements of application scenes, and the device has stable and reliable work and relatively economic cost.

The processor adopts a chip with a model of S32K144 and a NXP/Enzhipu brand, and the chip has a market price of less than one hundred yuan and is very economical and applicable.

The working principle of the testing device provided by the embodiment is very simple, and when actual testing is carried out, the telescopic sensor support 4 provided with the self-adaptive push-pull sensor 3 needs to be placed right below the middle of the scissor door 2, so that when the scissor door 2 is in a closed state, the scissor doors 2 on two sides can be in good contact with the self-adaptive push-pull sensor 3, the residual stroke of the scissor doors 2 is larger than the maximum measuring stroke of the self-adaptive push-pull sensor 3, and the self-adaptive push-pull sensor 3 can effectively measure the maximum effective clamping force of the scissor doors 2. If the height of the scissor door 2 is not consistent with the height of the adaptive push-pull sensor 3, the length of the sensor support 4 needs to be adjusted until the height is matched with the position of the scissor door 2 to be measured. The output interface 518 is connected to the gate 1 to be tested through a communication cable, so that the scissor door 2 of the gate 1 is driven to be opened or closed according to the measurement requirement through the relay driving module 516, and in this embodiment, the relay driving module 516 is designed as shown in fig. 11.

After the installation and position calibration are finished, the adaptive push-pull sensor 3 is clamped after the scissor door 2 is closed, in the process, the pressure applied to the adaptive push-pull sensor 3 is sent to the processor 510 in the form of an electric signal (analog electric signal) through the input interface 517, and the signal is processed by the processor 510 and then sent to the upper computer 9 in the form of a digital signal through the output interface 518 to perform operations including storage, display or output printing and the like. Thereby completing the measurement of the clamping force of the current scissor-type door 2 gate 1. Normally, two times of measurement are needed, if the two measurement results are within a normal range, the scissor door 2 of the gate 1 is determined to work normally, and the next device can be identified and measured. If the measurement result is abnormal, the measurement needs to be repeated, if the difference of the results of the two measurements is large, the installation position between the adaptive push-pull sensor 3 and the scissor door 2 needs to be checked repeatedly to determine whether the installation position is reliable, then the repeated measurement is performed, and the measured gate 1 is marked after the output measurement data is relatively stable so as to determine whether the overhaul is performed.

Usually, ten times of continuous tests are needed, and after the test is started, the processor 510 sends a command to the relay driving module 516 so as to control the opening and closing of the measured scissor door 2; and after the gate 1 is automatically opened due to protection or the acquired data exceeds a preset range, the scissor door 2 of the gate 1 is controlled to be opened, so that one test is completed. And when the preset waiting time of the system is reached, the measuring device controls the scissor door of the gate 1 to be closed, and the next test is carried out. In the testing process, the testing device caches the collected pressure values, the processor 510 displays the current maximum pressure value in real time by the pressure value collected by the adaptive push-pull sensor 3 through the display 8, and meanwhile, a pressure value curve is drawn. According to the above flow, after ten times of tests, according to the user's requirement, the option of storing the clamping force data obtained by the test can be selected, the collected data is stored in the storage module 515, and simultaneously, the collected data can be uploaded to the upper computer 9 for subsequent analysis, wherein the detailed functional description of the storage module 515 is as in embodiment 2 below.

The testing device provided by the embodiment can accurately and rapidly measure whether the scissor door 2 on the gate 1 is in a normal working state, and the gate 1 is overhauled one by one in a low-flow period (such as at night), so that faults can be eliminated in time, thereby avoiding unsmooth passage, and even causing damage to children or fragile articles. With this embodiment the measuring device just can be before the trouble takes place, the effective current efficiency of each floodgate machine 1 of further guarantee, the passenger who avoids peak period to lead to because of the trouble of floodgate machine 1 (for example cut the normal opening of door 2 or close etc.) goes out the problem that the station efficiency greatly reduced appears.
