2) When the triangle wood is correctly placed by an examinee, the triangle wood is attached to the piezoresistor on the triangle wood detection sensor, the resistance value of the piezoresistor is small, if the triangle wood is not correctly attached, the piezoresistor is not stressed, the resistance value is infinite, and the information acquisition instrument detects whether the triangle wood is placed and taken out; if the examinee blocks the piezoresistor by hand, the piezoresistor is unevenly stressed, the resistance change of the piezoresistor deviates from the situation that the triangle is correctly attached, the information acquisition instrument can distinguish cheating behaviors, and an alarm signal is sent out through the field terminal;
when an examinee takes an examination, the sleeve spanner is sleeved on the nut dismounting detection sensor, and the sleeve spanner is kept for a few seconds and then taken off; when the sleeve spanner is arranged on the sensor, the resistance is infinite, when the sleeve spanner is not arranged on the sensor, the photoresistor receives illumination, the resistance is small, and the information acquisition instrument detects whether the operation of unscrewing or screwing the spare tire nut or the large tire nut exists at the position; if the examinee blocks the photoresistor by hands, the shielding effect of the hands is different from that of the socket spanner, the deviation exists in the resistance change of the photoresistor, the information acquisition instrument can distinguish cheating behaviors, and an alarm signal is sent out through the field terminal;
when an examinee takes an examination, the jack is required to be arranged on the jack detection sensor; when the jack is correctly placed by an examinee, the illumination of the photoresistor is completely blocked, and the resistance value is infinite; meanwhile, the piezoresistor senses the pressure of the jack, and the resistance value of the piezoresistor is smaller at the moment; if the jack is not placed correctly, the photoresistor receives illumination, and the resistance value is smaller; the piezoresistor is not stressed, and the resistance value is infinite; the information acquisition instrument detects whether the jack is placed and taken out or not; if the examinee blocks the photoresistor by hands, the shielding effect of the hands is different from that of the socket spanner, the deviation exists in the resistance change of the photoresistor, the information acquisition instrument can distinguish cheating behaviors, and an alarm signal is sent out through the field terminal;
when the human body detection sensor detects that the examinee winds the car for one circle, the information acquisition instrument sends a signal that the examinee winds up to be qualified to the field terminal, and otherwise, sends a signal that the examinee winds up to be unqualified to the field terminal.
