3) loading and unloading operation: when a driver presses down a loading and unloading button, a normally open relay IV (19) is closed, a storage battery pack (1), a normally open relay I (2), a two-way relay (3), a brake opening switch (4), a conversion electric shock relay (5), a loading and unloading indicating lamp (8) and a motor I (7) form a control loop, at the moment, a door is automatically opened, and the vehicle is braked in an opening state;
4) monitoring operation: when the distance between the inner door of the carriage and the rear door frame (2-7) is too large or the temperature in the carriage is too high, the normally open relay III (17) is closed, the storage battery pack (1), the electromagnet part (18), the normally open relay III (17), the alarm indicator lamp (16) and the buzzer (14) form a control loop, at this time, a danger report is sent to the singlechip host (3-6) from the singlechip slave machine (4-1), the singlechip host (3-6) is transmitted to a driver through the LCD display module (3-1), and is transmitted to the server terminal (3-5) through the wireless communication module I (3-8); when the hydrogen concentration in the carriage exceeds a set threshold value, a control loop is formed by the storage battery pack (1), the electromagnet component (18), the normally open relay III (17), the alarm indicator lamp (16), the buzzer (14), the leakage indicator lamp (15), the normally open relay II (13) and the exhaust fan motor (11), and therefore the alarm can be sent, and the exhaust fan (2-12) at the back door can be opened.
