Abstract
The utility model discloses a load limitation device of an urban road gravel and sand vehicle. The load limitation device comprises a gravel and sand vehicle, wherein the gravel and sand vehicle is further provided with a pressure sensor, the pressure sensor is connected with an input end of a singlechip, and an output end of the singlechip is respectively connected with the microprocessor and a buzzer. The load limitation device disclosed by the utility model has the advantages of simple structure, and convenience for test, and brings convenience for an operator to effectively optimize the whole performance of the gravel and sand vehicle.
Description
Technical field
The utility model relates to the traffic safety field, is specifically related to a kind of load limitation device of urban highway sandstone car.
Background technology
Along with the process of China's rapid economic development and urban construction is accelerated day by day, the quantity of sandstone car also constantly rises in the city.Because lack sandstone car actv. administrative mechanism comparatively, sandstone car driver awareness of safety is generally relatively poor in addition, the overload of sandstone car is gone and the traffic accident quantity that causes also constantly rises, and has caused enormous economic loss and personal casualty thus.At present, urban highway sandstone car limit for tonnage regulation has been put into effect in many cities, but totally it seems, still lacks the actv. oversight mechanism, and a lot of vehicles are not still observed corresponding limit for tonnage regulation.
Summary of the invention
The purpose of the utility model is to provide a kind of urban highway sandstone car load limitation device; This device comprises the sandstone car; Pressure sensor also is installed on the sandstone car, and pressure sensor links to each other with the input end of micro controller system, and the mouth of micro controller system links to each other with buzzer phone with microprocessor respectively.
The utility model also has the other technologies characteristics:
Described micro controller system is a Freescale S12 model micro controller system.
Described pressure sensor is the US5100 pressure sensor.
Described microprocessor is the cRIO-9074 in the NI CompactRIO series.
Compared with prior art it is simple in structure for the utility model, and convenient test can be made the initiatively function of early warning to the sandstone car of overload rapidly.
Description of drawings
Fig. 1 is the principle schematic of this practical a kind of sandstone car load limitation device.
Below in conjunction with accompanying drawing the particular content of the utility model is done further explain.
The specific embodiment
With reference to Fig. 1, for present embodiment provides a kind of sandstone car load limitation device, comprise the sandstone car, pressure sensor also is installed on the sandstone car, pressure sensor links to each other with the input end of micro controller system, and the mouth of micro controller system links to each other with buzzer phone with microprocessor respectively.Wherein, pressure sensor is installed on sandstone car wheel place, and its signal wire (SW) is connected with the first input channel PM1 of micro controller system, is used to gather the pressure from car; Microprocessor is installed in the car operator's compartment, and its signal wire (SW) is connected with the first delivery channel PB1 of micro controller system, is used for the automobile car weight and is able to show through sensor; Buzzer phone is installed in the car operator's compartment, is used to send the alarm from car, is connected with the second delivery channel PB2 of micro controller system.
Wherein micro controller system adopts Freescale S12 model micro controller system.
During use, micro controller system is gathered the car weight from car in real time, and compares with the limit for tonnage value, judges whether and need send from the car alarm to buzzer phone; If surpass the limit for tonnage value from the car car weight, the Single-chip Controlling buzzer phone sounds the alarm, and prompting is noted unloading goods or out of service from the car chaufeur, avoids because the generation of the accident that overload causes; When from the car car weight less than the limit for tonnage value, buzzer phone quits work, vehicle can cruising.Used electronic devices and components all are commercially available known product in the device of the utility model, and those skilled in the art can realize the connection of each electronic devices and components according to the application's technique effect.
The utility model is not limited to the foregoing description, and those of ordinary skill in the art to the increase or the replacement of the unsubstantiality that technical characterictic carried out, all should belong to the protection domain of the utility model under the instruction of this specification sheets.
