the device is also provided with a self-checking air bag, the self-checking air bag adopts an old air bag in use, a new air bag is used for replacing the old air bag in use each time, and the old air bag is used as the self-checking air bag to be arranged at the self-checking port; the control host detects the change rule of the air pressure of the self-checking air bag broken due to overhigh temperature along with the temperature during the work, constructs a new temperature limit air pressure curve at regular intervals, and adjusts the working air pressure of the air bag to work at 80 percent of the limit air pressure, thereby not only preventing the air bag from being broken due to overhigh air pressure, but also preventing the detection sensitivity from being reduced due to overlow air pressure; the new temperature limit air pressure curve is constructed each time, so that the reduction of the air bag performance caused by the environment and the air bag aging can be effectively adapted;
the control host monitors the air pressure of all the air bags to enable the air bags to be always under the same air pressure, when the air bags are penetrated, the air pressure is rapidly reduced, the control host judges that the air bags are penetrated, and an alarm signal is sent;
the control host machine detects the inflation frequency of the air bags, and when the inflation frequency of a certain air bag is 2 times higher than the average value of the inflation frequencies of all other air bags, an alarm signal is sent to prompt the air bags and the belt to be overhauled;
the air pressure detector of each air bag has a unique number, and when the air pressure detector works, once an alarm occurs, the control host displays the number of the abnormal air pressure detector to a user.
