Abstract
The invention relates to a method for transferring tyre pressure by use of a radio. The method involves a pair of transmitting/receiving measuring devices on each tyre of a vehicle and a terminal receiver of a cab, and is characterized in that: after detecting the measured data of the tyre pressure, the transmitting/receiving measuring devices on all tyres transmit the obtained measured data to the transmitting/receiving measuring devices on the last tyre toward the cab (in a routing manner) until the transmitting/receiving measuring devices on the tyre closest to the cab transmit the measured data to the terminal receiver of the cab. The method provided by the invention can be used for transmitting the measured data of tyre pressure with the least transmission power, thus greatly prolonging the service life of the batteries configured in the transmitting/receiving measuring devices mounted on the tyres. If batteries with excellent performance are configured, the service life of the transmitting/receiving measuring devices can approach the service life of the tyres, thus the transmitting/receiving measuring devices are more beneficial to popularization and application.
Description
Technical field
The present invention relates to a kind of method of utilizing the radio transmitting tire pressure.
Background technology
In car running process, there is measurement mechanism to measure in real time each tire pressure at present, pressure value is transmitted on the reception facilities of operator's compartment by radio communication, perhaps show force value at automobile instrument panel.In the various wireless communication method, such as RFID, BlueTooth, Wi-Fi, UWB, WiMax, NFC and ZigBee etc., its prior art exists, mainly be emission the contradiction of receiving range and emissive power.In order to guarantee to receive the reliable and stable of signal, then launch receiving range arrange far, emissive power loss is large, will greatly shorten battery life.This is that it is without extraneous electric power supply because being contained in the power supply of the measurement tire pressure on the vehicle tyre is the battery that measurement mechanism carries, and the emissive power increase will directly cause the greatly shortening of measurement mechanism work-hours; And if transmitting range arranges excessively closely, when communication had interference, operator's compartment does not just receive data or data are imperfect, perhaps may run into various environment in the Vehicle Driving Cycle, be very easy to be subject to external interference, cause reception facilities in the operator's compartment to can not receive data or data are imperfect.Therefore demand inventing a kind of novel type of transmission urgently, to address the above problem.
Summary of the invention
The objective of the invention is to solve underproof or the short existing problem of measurement mechanism work-hours when vehicle tyre pressure transmits in the prior art, a kind of method of utilizing the radio transmitting tire pressure is provided.The present invention designs a kind of method of utilizing the radio transmitting tire pressure, comprise on each tire of vehicle a pair of emission receive measurement mechanism (being called for short MUC), the terminal receiver of operator's compartment, it is characterized in that: the emission on all tire receive measurement mechanism after detecting the take off data of tire pressure, with the emission on the nearest tire that leads to (routing mode) operator's compartment direction of the take off data that obtains receive the measurement mechanism transmission, emission on the next tire receive measurement mechanism on receiving the emission on nearest tire receive the take off data of the tire pressure that measurement mechanism transmits after, with the emission of received take off data on the nearest tire that leads to the operator's compartment direction receive the measurement mechanism transmission, until close to the emission on the tire of operator's compartment receive measurement mechanism with the terminal receiver of data transfer to operator's compartment.Advantage of the present invention is can be with the take off data of the pressure of the emissive power of minimum emission tire, will greatly prolong for this reason the emission that is installed on the tire receive service life of the battery that measurement mechanism disposes.As dispose the battery of function admirable, can make emission receive the service life of measurement mechanism close to the service life of tire.So that emission receive measurement mechanism and more be beneficial to and apply.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention (take four wheels as example),
1 is the terminal receiver of operator's compartment, 2 near the emission of the wheel of operator's compartment receive measurement mechanism, 3,4 for the emission of leaving operator's compartment wheel farthest receive measurement mechanism.The 5th, the emission of the wheel of intermediate distance receive measurement mechanism,
Below in conjunction with drawings and Examples the present invention is elaborated,
The specific embodiment
Comprise among the figure on each tire of vehicle a pair of emission receive measurement mechanism (being called for short MUC), the terminal receiver of operator's compartment, it is characterized in that: the emission on all tire receive measurement mechanism after detecting the take off data of tire pressure, with the emission on the nearest tire that leads to the operator's compartment direction of the take off data that obtains receive the measurement mechanism transmission, emission on the next tire receive measurement mechanism on receiving the emission on nearest tire receive the take off data of the tire pressure that measurement mechanism transmits after, with the emission of received take off data on the nearest tire that leads to the operator's compartment direction receive the measurement mechanism transmission, until close to the emission on the tire of operator's compartment receive measurement mechanism with the terminal receiver of data transfer to operator's compartment.Specifically be exactly that 3 pass to 5,5 passes to 2,2 again and pass to Isosorbide-5-Nitrae and pass to 2,2 and pass to 1, has so just formed from the most contiguous local signal transmission, until pass to the terminal receiver of operator's compartment.
One of technical bottleneck of current tire pressure measurement is that battery life is short, does not wait by 2 years in 6 months.Can't mate with the life-span of tire.This patent invention is to increase routing algorithm, and penetrating distance according to minimum emissive power and bob is data transfer path, and pressure signal is offered chaufeur.Improve the battery life of device for pressure measurement, guaranteed the accurately and reliably transmission of signal.Especially very high apart from ground for operator's compartment, a plurality of tires, even the heavy-duty vehicle of 10 above tires, the present invention more is practically applicable to such vehicle.
