Vehicle load overweight monitoring alarm device

Abstract

The invention discloses a vehicle load overweight monitoring alarm device. The device comprises a casing, a power supply, a microprogrammed control unit (MCU), a vehicle weight information acquisition module, a global position system (GPS) positioning module, a global system for mobile communication (GSM) network short message transmitting module and a monitoring center, the power supply, the vehicle weight information acquisition module, the GPS positioning module and the GSM network short message transmitting module are connected with the MCU, the power supply, the vehicle weight information acquisition module, the GPS positioning module, the GSM network short message transmitting module and the MCU are placed in the casing, the vehicle weight information acquisition module comprises an ultrasonic sensor, the ultrasonic sensor can detect the change of the distance between a vehicle girder and an axle when the vehicle is loaded, the ultrasonic sensor is calibrated through data acquisition test so as to indirectly measure the vehicle load weight, and the monitoring center comprises a management upper computer and a GSM network short message receiving module. By means of the vehicle load overweight monitoring alarm device, the overload alarm work can be stably and accurately completed, and the real-time monitoring for the overload vehicle can be achieved.

Description

technical field [0001] The invention relates to a monitoring and alarming device, in particular to a vehicle-mounted overweight monitoring and alarming device. Background technique [0002] Overloaded transportation of vehicles has a great impact on the healthy development of the national economy. Overloaded transportation not only endangers the safety of people's lives and property, but also damages the environment and affects national order. In order to suppress the damage caused by vehicle overload, research on vehicle overload detection technology has been carried out since the late 1950s at home and abroad. At present, the systems used for vehicle weight detection mainly include static weighing and dynamic weighing in terms of detection methods. By the 1990s, mature products have been formed, and the products have also developed from static weighing to dynamic weighing. At present, there are mainly the following dynamic weighing methods: ADV method, DV method, V method,...

Problems solved by technology

However, this method not only consumes a lot of manpower and material resources, but also has a large number of places that cannot be supervised. In areas far away from the inventory point, the phenomenon of overloading cannot be investigated.

In addition, the on-board weighing products developed by the traditional weighing method need to change the car body structure, and it is difficult to find a suitable installation position on the car
