Description

A kind of trailer car tyre pressure monitoring system
Technical field
The utility model relates to a kind of tire pressure monitoring system (TPMS), concretely, relates to a kind of monitoring system that manages in the data such as tire pressure that do not having under the situation of headstock separately trailer.
Background technology
TPMS is the english abbreviation form of tire pressure monitoring system " Tire Pressure Monitoring System ", simple saying is exactly when vehicle travels or stop, pressure and temperature to vehicle tyre is monitored in real time, the pressure and temperature that guarantees tire maintains in the standard range, play and reduce the probability of blowing out, ruin tire, reduce the damage of oil consumption and vehicle part.
TPMS is by installing highly sensitive sensor at each tire, data such as the pressure of real time monitoring tire, temperature under driving or static state, and be transmitted into the built-in receptor of central monitor by wireless mode, central monitor is reminded the motorist with above-mentioned data in the telltale demonstration or with forms such as buzzings, and change at tire flat and pressure and to surpass safe thresholding (this threshold value can be set by telltale) time and report to the police, with guarantee driving safety.
The TPMS that uses on the truck is made of following major part:
1. sensor
Sensor is installed on the tire, and the pressure and temp information of detected tire is formed data flow, sends out in the mode of less radio-frequency.
2. telltale
Telltale can receive the information that sends from the closer sensor of telltale distance, and the information that sensor is sent is extracted then, and the position of corresponding each tire then shows the pressure and temp information of each tire in some way.
3. intelligent repeater
Be installed on the trailer, management is installed in the sensor on the trailer car tyre, will receive trailer upper sensor information and be forwarded to the telltale demonstration.
Along with the development of transit industry, large-scale trailer is used more and more general, and the characteristics of trailer are that its headstock is constant always, but the trailer portion that articulates mutually with it branch is often changed.Some fleet simultaneously, headstock and trailer are not same companies, how separately management also is to adhere to different companies separately, the new problem that just becomes of the tire pressure temperature of monitor trailer part.
Summary of the invention
At the problems referred to above, the utility model aims to provide a kind of under the situation that does not have headstock, separately the system for monitoring pressure in tyre that trailer tire is monitored.

Fig. 3 is the workflow diagram of the present invention's intelligence repeater.
The specific embodiment
Beneficial effect in order more properly to describe the present invention and to bring is described further the present invention below in conjunction with accompanying drawing, but content of the present invention and protection domain are not limited to the content that the specific embodiment is explained.
The present invention is described further below in conjunction with Fig. 1 to 3:
Now the specific embodiment of the present invention is described further:
The trailer car tyre pressure monitoring system comprises the sensor that is installed on the tire, and is installed in the intelligent repeater on the trailer, and intelligent repeater manages sensor by the mode of radio communication, and handheld tool.
As shown in Figure 1, handheld tool comprises: power supply module, and the central process unit first, less radio-frequency receptor first (RF-RECEIVER), radio frequency transmitter first (TX-RF), the telltale first, keyboards etc. are partly formed.
Wherein power supply module is made up of power supply and power supply changeover device, and power supply is mainly finished the 9V power supply and transferred the 5V power supply to, and power supply changeover device is finished a 5V power supply and transferred the 3.6V power supply to.
The central process unit first is the main logic control element of being responsible for information processing, also is used for preserving data simultaneously.
Less radio-frequency receptor first mainly is responsible for receiving the RF signal of assigned frequency section, and transfers digital signal to.
The main RF signal of being responsible for sending the assigned frequency section of radio frequency transmitter first TX-RF part;
The telltale first is mainly used in showing data, as sensor ID sign indicating number, pressure, information such as temperature.
Keyboard is mainly used in importing data, as sensor ID sign indicating number, standard pressure etc.
Handheld tool carries out the initialization setting by the radio communication mode to repeater, will be input in the handheld tool with the sensor ID sign indicating number of tire opposite position by keyboard, by the radio frequency transmitter first configuration information is sent in the intelligent repeater and preserves.When service personnel need be checked the tire pressure information of this vehicle, by the button on the operation handheld tool, just can send an order of reading intelligent repeater information, this order sends to intelligent repeater by the radio frequency transmitter first, information such as the tire pressure of the intelligent repeater transmission of wait reception, temperature receive the back and show by telltale then.
As shown in Figure 2, intelligent repeater mainly comprises: power supply second, power supply changeover device second, central process unit second, less radio-frequency receptor second (RF-RECEIVER), radio frequency transmitter second (TX-RF), alarming device six parts.Wherein:
Power supply second transfers the 12V/24V power supply to the 5V power supply.
Power supply changeover device second transfers the 5V power supply to the 3.6V power supply.
Central process unit second mainly is responsible for the logic control element to the processing of information, also is used for preserving data simultaneously.
Less radio-frequency receptor second mainly is responsible for receiving the RF signal of assigned frequency section, and transfers digital signal to.
Radio frequency transmitter second mainly is responsible for sending the RF signal of assigned frequency section;
Alarming device, whether be used to refer to trailer car tyre pressure unusual;
As shown in Figure 3, principle of work of the present utility model is: open less radio-frequency receptor second and radio frequency transmitter second after intelligent repeater powers on, beginning received RF information.When a RF signal is come, whether judge the RF signal and be kept at sensor ID sign indicating number coupling in the intelligent repeater, if coupling then preserve, compare with the standard pressure of keeping then, if be lower than default numerical value, then send warning, as light alarm lamp.No matter repeater receives to such an extent that whether whether signal (data such as the pressure of tire, temperature) consistent with numerical value default in repeater, repeater all is transmitted to this RF information the telltale first and shows.
If this RF signal and the sensor ID sign indicating number that is kept in the intelligent repeater are unmatched, then judge whether the order of reading pressure information of sending for handheld tool, if, then by radiofrequency launcher second information such as the tire pressure of all trailers, temperature, standard pressure are sent at once, after handheld tool receives, all show.
Like this, on the trailer that telltale is not installed, can pass through the utility model, monitor, detect tire pressure, the temperature information of independent trailer part fast and effectively.
