The invention discloses a code matching instrument for a car tire blowout warning device, which is characterized in that it includes a central processing unit, a radio frequency module, a low-frequency transmitter, and external input buttons; the radio frequency module is connected to the input port of the central processing unit, and the low-frequency transmitter is connected to the The output port of the central processing unit is connected, and the external input buttons are connected with the input port of the central processing unit; in addition, a display device is also included, and the display device is connected with the output port of the central processing unit. The device of the present invention completes code matching by determining the ID number of the transmitting device to ensure that the receiving device receives data correctly. It solves the above-mentioned problems that the ID number of the receiving device of the former is fixed, which brings about commissioning and replacement; and the problem that the latter has a complex structure and narrow use area. Therefore, the debugging and replacement of the automobile tire pressure monitoring system are simple, the adaptability is wide, and it can be applied to automobiles in large quantities.
Description
technical field [0001] The invention relates to a coding instrument for an automobile tire blowout warning device used in an automobile tire pressure monitoring system. Background technique [0002] Automobiles are the main means of transportation in modern society. Automobile tires are the main pressure-bearing parts of automobiles. Whether they work under normal pressure is a necessary condition for the normal driving of automobiles, and it is also an important factor to ensure the safety of vehicles and passengers. links. If the tire pressure is insufficient (negative pressure) or the pressure of the tire is too high (overpressure) due to too much cargo, too high temperature, etc., it is very easy to cause a traffic accident; Excessive pressure (overpressure) causes traffic accidents caused by tire blowouts to occur frequently, and has repeatedly caused major and extraordinarily serious traffic accidents of car crashes and fatalities. According to statistics: 70% of tra...
