In recent years, the number of private cars in China has increased year by year. On the one hand, it shows a significant increase in people's living standards, and on the other hand, it means that road safety is facing severe challenges. Driving safety has become the focus of more and more car owners. The four tires are the only components that contact the road with the entire vehicle. They are the basis for supporting the car. Whether the tires are normal or not has a direct impact on driving safety.
According to the statistics of traffic accident data in China, 70% to 80% of traffic accidents on expressways are caused by abnormal tire pressure, of which 46% are caused by tire blowout. However, in real life, many car owners do not take the initiative to check the tire pressure, and it is difficult to really distinguish whether the tire pressure is normal by the way of kicking the tire. For the safety of oneself and others, it is necessary for car owners to carry out tire pressure test consciously, scientifically and rationally.
How can we understand the status of the tires in real time and prevent sudden blowouts? In addition to daily attention, many owners are aware of the need to install tire pressure monitoring systems. Nowadays, the market is full of various brands and models of tire pressure monitor system. So, how can you buy a quality guaranteed TPMS?
TPMS is a wireless transmission technology that uses high-sensitivity micro-wireless sensing devices fixed in the tires of a vehicle to collect data such as pressure and temperature of the automobile tires while driving or stationary, and transmits the data to the host computer.
The vehicle tire pressure and temperature and other related data are displayed in real time in digital form, and the vehicle active safety system is alerted to the driver in the form of buzzer or voice in the case of abnormal tires. This ensures that the pressure and temperature of the tires are maintained within the standard range, thus reducing the probability of punctures, damage, and reducing fuel consumption and damage to vehicle components.
The chip solution has a great impact on the effect of TMPS. Generally, tpms with large amount of chips, good stability and good economy is selected.
PCB is a weak signal and the modulation frequency band of data transmission is roughly in amateur frequency band. There are many factors affecting PCBs such as circuit layout, structure, and electromagnetic compatibility. The design power of PCB needs the support of expensive special tester, as well as the rich PCB design experience of transmitting and receiving circuit.
As we all know, tire pressure monitoring is also a kind of intelligent equipment, including hardware and software. The hardware should not only use a good chip, but also have a good transmitting and receiving device. The software is to coordinate the stability of the whole tire pressure monitoring system, alarm timely and accurately, and the convenience of operation.
Different designers will have great differences. Even in the seemingly similar TPMS, the structure of the code and the algorithm can be described as very different. Only by continuously studying the massive data in depth and through machine learning can designers achieve accuracy and stability. So the professional manufacturers are trustworthy, especially those who have obtained industry-related software copyright certificates.
Users may be concerned about the fact that the battery life is too short and uneconomical. In terms of high-speed performance, professional brands for example gussin, generally can maintain a stable level of more than 160 kilometers without losing signals.
In summary, in the same mode of use, there is still a gap between the comprehensive and professional manufacturers in terms of program design, chip selection, material technology, and the conditions permit to buy TMPS produced by professional manufacturers.
