Problems solved by technology

At present, battery-powered technology is commonly used in direct tire pressure monitoring systems. However, with the increasing power consumption of electronic modules in smart tires, increasing battery capacity will inevitably affect the dynamic balance of tires at high speeds. The high temperature and high pressure environment in the battery also makes the battery a potential safety hazard for tires.

Embodiment Construction

[0018] Below in conjunction with embodiment and attached Figure 1-3 The present invention is further explained so that those skilled in the art can implement it with reference to the description. The following examples are only used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] Such as figure 1 Shown is the system block diagram of the content of the present invention, the whole system is powered by the power supply system, and the power supply system deforms the piezoelectric film sensor through external pressure to generate charges. The power supply module is connected with the voltage conversion module in the RFID chip; the voltage conversion module is connected with the core microcontroller MCU to supply power to the entire RFID chip. The information storage module, communication module, GPRS module, PVDF sensor, temperature sensor, and acceleration sensor are also connected to the core microcontroller MCU...

Abstract

The invention relates to a passive tire monitoring system, comprising a radio frequency identification (RFID) chip, an antenna and a power supply module, wherein the power supply system causes a piezoelectric thin-film sensor to deform by means of external pressure so as to generate charges, and then supplies power to a circuit on the RFID chip by means of a voltage conversion module. The conditions, such as tire pressure, acceleration, temperature and other data, in a tire are monitored in real time by means of a communication module and multiple sensor modules on the RFID chip, so that large-scale sensor nodes and battery power supply can be avoided, the level of safety in vehicle operation is improved, the whole tracking of the tire in a whole life cycle can be realized, and the information management level of the tire is improved.

Description

technical field [0001] The invention relates to a passive tire monitoring system, which belongs to the fields of machinery and electronic information. Background technique [0002] In the process of tire manufacturing and after-sales service, the correct collection and storage of tire information plays an important role in the control of tire production process, quality inspection, quality tracking management, and use and maintenance. At present, in the actual production and use of tires, barcodes, sidewall information and paper records are mainly used for identification and management. However, due to the large number of tires, frequent circulation, and high frequency of data update, on the one hand, it will cause problems such as the accuracy and efficiency of tire information identification, which will lead to a serious disconnection between the front and rear of tire production information; on the other hand, when there is a problem with tire quality, it cannot Obtain a...
