Description
Technical field
The present invention relates to a kind of tire pressure weight measuring system.
Background technology
In mid-June, 2006, national correlation department is formally implemented the weight metering charging scheme, and increasing province comes into effect weight metering charging system.Existing lorry is not because have effective check weighing instrument, driver not to know how many actual weights of each shipments that the sender sends off is, estimates with feeling often, charges carriage by weight then.More than with feeling to come estimation approach often to bring more or less loss to the driver, directly reduced driver's income.
There have been air pressure of automobile tire measurement or monitoring equipment coming into operation recently.It is by inserting pressure transducer, microcontroller, transmitter in doughnut inside; The tire pressure signal that signal receiver in pilothouse, processor, display reception tire pressure sensor, transmitter emit receives, handles the pressure data that the back display shows its tire by the signal receiver in the pilothouse, processor.This technology and equipment is existing mature technology and extensively utilization.But this system equipment is the single pressure value that applies to measure and monitor in the doughnut at present, and is the pressure value in the single tire, prevents automobile flat tire, the security when improving running car, the serviceable life of improving fuel availability and tire.Often go up at present not have as yet and aly place inside tires with tire pressure sensor, microcontroller, transmitter, the tire pressure receiver, converter, Single Chip Microcomputer (SCM) system, display, operation control panel place in the pilothouse, by wireless transmission and be used to measure tire pressure weight measuring system with display automobile loading dead weight capacity.
Summary of the invention
The purpose of this invention is to provide a kind of tire pressure weight measuring system.
A kind of tire pressure weight measuring system is characterized in that comprising:
The above tire pressure sensing control transmitter unit of one cover;
One rf receiver unit;
One converting unit links to each other with Single Chip Microcomputer (SCM) system with the frequency receiving element respectively;
One display unit links to each other with Single Chip Microcomputer (SCM) system;
One operation control unit links to each other with Single Chip Microcomputer (SCM) system;
One power supply links to each other with Single Chip Microcomputer (SCM) system, operation control unit links to each other.
Tire pressure control transmitter unit comprises pressure transducer, micro-control unit, rf transmitter unit and power supply; Each tire is installed a tire pressure control transmitter unit, so its quantity is more than the cover, to be pressure data that all pressure transducers are measured be transmitted into rf receiver unit by its rf transmitter unit in the mode of radio transmission to its function simultaneously; Rf receiver unit is accepted the electric signal that all rf transmitter units are sent simultaneously, is transferred to converting unit after the aggregation process, via after the Single Chip Microcomputer (SCM) system output, and display unit display digit signal, thus obtain the weight of carload goods.
When the automobile loading, its vehicle body deadweight, the loading goods weight bears by the vehicle tyre of automobile, and the pressure that its inside tires is born is directly proportional with vehicle body deadweight additional cargo goods weight sum.The pressure transducer induction pressure that is installed in inside tires is converted into electric signal, after handling, micro-control unit is converted into radio signal by rf transmitter unit, rf receiver unit in the pilothouse is accepted the electric signal that all rf transmitter units are sent simultaneously, display shows after converting unit, Single Chip Microcomputer (SCM) system are handled, thereby changes the pressure in the tire into the automobile pay load.
Its beneficial effect: can combine with existing air pressure of automobile tire measurement or monitoring equipment, system, in not bigger its cost of increase, can not only obtain the pressure value in the tire, prevent automobile flat tire, security when improving running car, improve the serviceable life of fuel availability and tire, and can also realize monitoring pressure constantly, multiple function such as check weighing.
Description of drawings
Fig. 1 is a systematic schematic diagram of the present invention.
Embodiment
Referring to accompanying drawing 1, tire pressure sensing control transmitter unit 1 comprises pressure transducer, micro-control unit, rf transmitter unit and power supply; Pressure transducer, micro-control unit link to each other, and pressure transducer changes the pressure physical quantity of the inside tires that obtains into electric pressure signal passes to micro-control unit; Micro-control unit links to each other with rf transmitter unit, receives the data (electric pressure signal) that pressure transducer transmits, and exports to rf transmitter unit after treatment, and its function is that the transmitting control commands signal is given pressure transducer.
Tire pressure receives display unit 2 and comprises: rf receiver unit, converting unit, Single Chip Microcomputer (SCM) system, display, operation control panel and power supply; Rf receiver unit links to each other with converting unit, and rf receiver unit is accepted the electric signal that all rf transmitter units are sent simultaneously, is transferred to converting unit after the aggregation process; Converting unit is discrete digital signal with electric signal amplification, methodization that rf receiver unit receives with the continually varying conversion of signals; Converting unit links to each other with Single Chip Microcomputer (SCM) system, and the signal that is produced in the converting unit is changed out digital signal (BCD) sign indicating number under the control of Single Chip Microcomputer (SCM) system; Operation control unit is connected with Single Chip Microcomputer (SCM) system, in order to system's input command and data; Display unit is connected with Single Chip Microcomputer (SCM) system, shows the digital signal of single-chip microcomputer output; Power supply is connected with operation control panel with Single Chip Microcomputer (SCM) system, power supply provides stable electric current for the operate as normal that tire pressure receives display unit, the output of its electric current is subjected to the control of operation control panel, operation control panel sends command signal to power supply, and making that power supply is in good time exported or close current.
During use, open automobile power source, tire pressure receives the display unit energising, tire pressure weight measuring system is started working, operation control unit sends the check weighing instruction, power supply provides electric current to single-chip microcomputer, to instruct simultaneously via Single Chip Microcomputer (SCM) system, converting unit, the rf receiver unit firing order receives for the rf transmitter unit in each tire pressure sensing control transmitter unit, give pressure transducer instruction issuing via micro-control unit, after pressure transducer is received instruction, after handling, micro-control unit is converted into radio signal by rf transmitter unit, rf receiver unit in the pilothouse is accepted the electric signal that all rf transmitter units are sent simultaneously, through converting unit, Single Chip Microcomputer (SCM) system is handled the back display and is shown, thereby changes the pressure in the tire into the automobile pay load.
