Description
Technical field
The utility model relates to a kind of car alarm system, relates in particular to the carload warning system.
Background technology
China every year is because of the loss that the vehicle overload overload causes surpasses 30,000,000,000 yuan, makes the goods stock of normal tenure of use about 10 years, will scrap after 2 to 3 years.In recent years, the vehicle overload overload has a strong impact on national wealth and people's life safety, jeopardizes social economic order, has become an outstanding social concern, has obtained national great attention.The vehicle overload overload also is the one of the main reasons that causes road traffic accident in addition, according to statistics, more than 660,000 of road traffic accident took place in the whole nation altogether in 2003, cause 10.4 ten thousand people's death, 49.4 ten thousand people injured, 33.7 hundred million yuan of direct economic losses, total number of accident and Wan Che mortality ratio occupy first place in the world, and in these accidents, 70% is relevant with the automobile overrun and overload.
China ZL01231289.4 discloses a kind of carload warning device, and it does not possess the function that the carload data in real time is offered vehicle supervision department, can not make vehicle supervision department understand the load-carrying situation of travels down automobile in real time; In addition, the employed steel ball of pressure transducer damages easily in this carload warning device, and manufacturing cost is higher, makes that the cost of equipment set is just very high.
Summary of the invention
The purpose of this utility model is the above-mentioned weak point that solves prior art, providing a kind of can be controlled at vehicle capacity in the load-carrying weight range that vehicle appraises and decides effectively, prolong vehicle service life, avoid the traffic hazard that overloads and travel and caused, carload lot can be offered in real time the carload warning system of vehicle supervision department simultaneously.
The utility model comprises pressure transducer, regulator, single-chip microcomputer, PC, keyboard, display and gps satellite locating device, described pressure transducer is connected by regulator with single-chip microcomputer, and single-chip microcomputer is connected with PC, keyboard, display and gps satellite locating device respectively.
Described pressure transducer comprises shell, strain chip, pressing plate, supporting plate, and described strain chip is arranged in the shell circular hole, and described pressing plate is arranged in the groove of shell upper, and pressing plate top is equipped with supporting plate; Described pressure transducer is installed between lower vehicle steel spring plate and the tire axle or the beneath base channel-section steel of crossbeam is middle or the horizontal and vertical weld of chassis U section steel beam.
Advantage of the present utility model is:
(1) because the utility model has adopted the gps satellite locating device, the load capacity that records can be transferred to directly display alarm on the electronic chart of vehicle supervision department, and accurate display automobile dead weight capacity, the position and the number-plate number are convenient to vehicle supervision department's inspection supervision;
(2) because the steel ball in the pressure transducer is replaced to pressing plate, make the manufacturing cost of whole pressure transducer significantly reduce;
(3) because pressure transducer is installed in the horizontal and vertical weld of chassis U section steel beam, in the contact and stressed degree of support that increase sensor, can not damage the vehicle one-piece construction, and reliable operation, be convenient to safeguard.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model carload warning system, comprise pressure transducer 1, regulator 6, single-chip microcomputer, PC, keyboard, LCD and gps satellite locating device, pressure transducer 1 is connected by regulator 6 with single-chip microcomputer, and single-chip microcomputer is connected with PC, keyboard, LCD and gps satellite locating device respectively.As shown in Figure 2, pressure transducer 1 is installed between lower vehicle steel spring plate 4 and the tire axle 7, pressure transducer 1 also can be installed in the middle of the crossbeam 5 beneath base channel-section steels, preferably be installed in the horizontal and vertical weld of chassis U section steel beam, contact and stressed degree of support that like this can pressure boost sensor 1 can not damaged the vehicle one-piece construction.Regulator 6 has adopted the data peaks method of average of weighing, and when weighing the data transient fluctuation, the fluctuation data is not gathered, but gets the interior average sample value of its one-period, and the stress data with each position is transferred to single-chip microcomputer then.Whether the utility model can be used for measuring the charging capacity of automobile above appraising and deciding standard, when charging capacity exceeds standard, this device can (the GPS receiver be by its numerical control interface, utilizes the RS232C interface to link to each other with the computing machine communication port as between data terminal equipment and the computing machine by gps system.Can realize the reception of gps signal by communication port is programmed) on the electronic chart of vehicle supervision department, directly show automatically and report to the police, and accurately show goods weight, and the orientation, automobile place and the number-plate number, the inspection of being convenient to vehicle supervision department is supervised.
Gps system is a kind of radio navigation, location and multifunction system regularly of integrating.The miniaturization OEM plate of GPS receiver is combined with single-chip microcomputer, utilize the data message of its output, the configuration corresponding peripheral device can be developed the GPS application system.Information (also can be matched the interface of RS422 and RS485 by RS232C, communications protocol can be according to customization) serial port sends into single-chip microcomputer, accurately locate its position by GPS again, full detail is sent into PC by single-chip microcomputer by the RS232C serial port, deposit map data base in, also can on LCD, show its information by keyboard.The GPS communications protocol is set to baud rate: 4800b/s; Data bit: 8b; Parity check bit: do not have; Start bit: 1b; Position of rest: 1b.Utilize the GPS receiving system outwards to export a data characteristic p.s., make single-chip microcomputer be in query State, it is effective to detect RS232C receiving end RXD signal, begins to receive data.
As shown in Figure 3, pressure transducer comprises shell 12 among the China ZL01231289.4, be arranged on the strain chip 14 in the shell circular hole 13, the stressed steel ball 15 that is arranged in the shell 12 top arcs of recesses grooves reaches and the contacted supporting plate 16 in stressed steel ball 15 upper ends, its principle of work is such: this pressure transducer is installed in above the automobile spring plate 4 beneath tire axles 7, fasten by newel 10 pressures, when automobile is loaded onto goods, can press down after steel spring plate 4 is stressed, middle not withstood by newel 10 of pressure transducer this moment can be out of shape sinking, and steel spring plate 4 two ends bend by pressure distortion are sunk, directly be pressed on the steel ball 15 by supporting plate 16, steel ball 15 compresses shell 12 again, shell stressed back distortion, the strain chip 14 of dress in the influence sends the signal of contained goods weight after strain chip 14 is stressed.Because the cost of steel ball that this pressure transducer uses is higher, makes that the manufacturing cost of whole pressure transducer is very high.In order to address this problem, as shown in Figure 4, the stressed steel ball 15 with pressure transducer in the utility model replaces to pressing plate 19, act directly on the pressing plate 19 after supporting plate 16 is stressed, compressing shell 12 by pressing plate 19 influences strain chip 14, and effect is with original the same, but expense significantly reduces.
