[0002] Tires are an important part of the car. Whether the tires are normal or not is very important to the driving safety of the vehicle. The consequences of accidents caused by the tires are very serious, and the tire pressure is the most important parameter of the tires, so keep it at Driving under the correct tire pressure is of great benefit to the personal safety of the car owner and the maintenance of the car. Normal tire pressure is not only important for safety, but also very effective for fuel economy. Generally, when the car is running at high speed, tire failure It is the most worrying and most difficult to prevent for all drivers, and it is also an important reason for sudden traffic accidents. How to prevent tire blowouts has become an important issue for safe driving. Buzzer to alarm, but because of the negligence of the driver and the many warning lights, the driver cannot quickly distinguish which system gives the warning, which distracts the driver's attention. In order to solve the above shortcomings, the present invention provides A wireless car tire safety monitoring voice alarm system

Embodiment Construction
[0013] see figure 1 , figure 2 The present invention mainly comprises: the pressure that can be placed in the tire and temperature detection launch device 1,2,3,4 and the receiving device 5 that is installed in the automobile cab two parts, the microprocessor output terminal on the receiving device 5 and the unit The single-chip solid-state language integrated circuit 8 is connected to the input terminal of the voice analog signal, which can directly complete the input, storage and recall of the voice analog signal. The single-chip solid-state language integrated circuit 8 is an analog data acquisition system, which uses direct analog storage technology to complete the language Recording, storing and calling out in segments, unlike other language circuits, it has to go through complex digital signal processing processes such as A / D, D / A conversion, digital compression, and language synthesis. The information recorded and played can be directly recorded in EEPROM storage. In ...

The present invention relates to a wireless car tyre safety monitoring speech alarm system. Said system mainly includes two portions of pressure and temperature detection transmitting device, which can be placed in the interior of tyre and receiving device mounted in the cab. It is characterized by that the receiving device is connected with speech integrated circuit; the information can be directly recorded in EEPROM storage unit by means of microphone. When the receiving device is worked, said system can execute control program inputted into microcomputer, if the tyre produces abnormal condition, the receiving device can drive single-chip solid speech integrated circuit to give out speech alarm.
