Tire Pressure Monitor System (TPMS) is a system that automatically monitors the tire pressure in real time during the driving process of the car and warns the tires of air leakage and low air pressure to ensure driving safety. The following is a detailed introduction to the TPMS and an analysis of the role of the touch screen in it:
Tire pressure detection system is mainly divided into two types: indirect tire pressure monitoring system and direct tire pressure monitoring system.
Indirect tire pressure monitoring system (Wheel-Speed Based TPMS, referred to as WSB):
Working Principle: The wheel-speed sensor of the vehicle's ABS system is used to compare the difference in rotational speed between tires for the purpose of monitoring tire pressure. When the tire pressure decreases, the weight of the vehicle will make the tire diameter smaller and the speed of the vehicle will change, which can be used to trigger the alarm system to warn the driver.
Advantages and disadvantages: relatively low cost, but not as accurate as direct systems, and cannot determine the true condition of the faulty tire.
Direct Tire Pressure Monitoring System (Pressure-Sensor Based TPMS, PSB for short):
Working Principle: Using pressure sensors mounted on the tires to directly measure the air pressure of the tires, a wireless transmitter is used to send the pressure information from the inside of the tires to the system on the central receiver module, and then the air pressure data of each tire is displayed. The system will automatically alert you when the tire pressure is too low or leaking.
Advantages and disadvantages: Provides more advanced functions, determines the actual instantaneous pressure inside each tire at any time, and easily identifies the faulty tire. However, the cost is relatively high, and there are wireless signal transmission stability and reliability, the service life of the sensor and other issues.
In addition, there is a composite TPMS, which has the advantages of both indirect and direct two systems, in two mutually diagonal tires equipped with direct sensors, and equipped with a four-wheel indirect system. This composite system reduces costs and overcomes the inability of the indirect system to detect low air pressure in multiple tires at the same time, compared to using the direct system in its entirety. However, it still does not provide real-time data on the actual pressure in all tires as the direct system does.
As a high-tech product, touch screen plays an important role in tire pressure detection system. The following is the main role of the touch screen in the tire pressure detection system:
1. Intuitive and easy to use
With its intuitive operation interface and graphical display, the touch screen makes it easy for drivers to view key information such as tire pressure and temperature. Compared with the traditional digital display or indicator light alarm, the touch screen provides a richer visual feedback, reducing the difficulty of operation, so that drivers can quickly get started without professional training.
2. Real-time and accuracy
The display can update the tire pressure data in real time, to ensure that drivers use the touch screen to grasp the tire status at any time. This real-time is crucial for preventing tire failure and ensuring driving safety. At the same time, the high-precision display of the touch screen also ensures the accuracy of the data, avoiding the safety hazards caused by false alarms or omissions.
3. Interactivity and Personalization
The touch screen allows the driver to interact with the system, such as setting alarm thresholds and viewing historical data. This interactivity allows drivers to personalize the system according to their needs and preferences, improving the flexibility and adaptability of the system. In addition, the touch screen also supports multiple language options, which is convenient for drivers from different countries and regions.
4. Reliability and Stability
The touch screen adopts advanced display technology and material, which has excellent reliability and stability. In the harsh driving environment, the touch screen can still maintain a good display effect and operational performance, to ensure that the driver can accurately obtain tire pressure information. In addition, the touch screen is also anti-scratch, dustproof and waterproof, which prolongs the service life and reduces the maintenance cost.
5. Safety and warning function
Touch screen in the tire pressure detection system also plays an important role in safety. When the tire pressure is abnormal, the tire pressure detection system can immediately send an alarm to remind the driver to use the touch screen to take appropriate measures. This early warning function helps to prevent traffic accidents caused by tire failure, to protect driving safety.
