Tire-pressure instrument with function of recording pressure value

Abstract

The invention discloses a tire-pressure instrument with a function of recording a pressure value. The tire-pressure instrument comprises a sensor, a processor, a storage unit and a backup system, wherein the sensor is connected with the processor and an air nozzle; the air nozzle aligns to an inflating hole of an automobile tire; the air pressure in the tire is transmitted to the sensor, and the sensor converts the air pressure into a voltage signal and transmits the voltage signal to the processor; the processor is respectively connected with a button group, an alarm, the storage unit and a display; a reference value is set on the button group, and the alarm and the display are output modules; the storage unit realizes interaction of various data by synchronous mirroring or remote asynchronous mirroring; and the storage unit is internally provided with a dual-redundant controller and an automatic backup module, wherein the dual-redundant controller is used for controlling safe operation among storages. The tire-pressure instrument disclosed by the invention has the advantages that the alarming function is achieved, the application range is wide, the energy is saved, the offline backup of data of a database is realized, and the search of data information is fast and convenient.

Description

technical field [0001] The invention relates to the technical field of tire pressure meters, in particular to a tire pressure meter with the function of memorizing pressure values. Background technique [0002] Cars are an important means of transportation for our daily travel and cargo transportation. The safety of cars is very important. There are many factors that affect car safety. Tire pressure is also one of them. Unsuitable tire pressure can also cause safety accidents. Excessive tire pressure The meeting will affect the service life of the tire, and it is easy to cause traffic accidents due to exposure of the tire. When the tire pressure is too low, it will increase the power loss of the car and increase the fuel consumption of the car, which is not conducive to energy saving. The tire pressure will not be too large or too small, which is generally achieved by using a car tire pressure gauge. The existing car tire pressure gauge basically measures the tire pressu...

[0002] Cars are an important means of transportation for our daily travel and cargo transportation. The safety of cars is very important. There are many factors that affect car safety. Tire pressure is also one of them. Unsuitable tire pressure can also cause safety accidents. Excessive tire pressure The meeting will affect the service life of the tire, and it is easy to cause traffic accidents due to exposure of the tire. When the tire pressure is too low, it will increase the power loss of the car and increase the fuel consumption of the car, which is not conducive to energy saving. The tire pressure will not be too large or too small, which is generally achieved by using a car tire pressure gauge. The existing car tire pressure gauge basically measures the tire pressure of the car tire and compares it with the reference value. To judge whether the tire pressure is within the normal range, it will not compare itself with the reference value. It requires the user to compare the measured value with the reference value. Because of different models, the reference value of tire pressure is also different. The tire pressure is also different, which is inconvenient for users to use. In addition, the car tire pressure gauge uses a lithium battery, and the lithium battery generally needs to be replaced with a new battery after one year of use. In addition, the existing tire pressure gauge is set when it leaves the factory. Baseline value, this kind of tire pressure gauge is suitable for specific models and has a small range of use
