Description

A new type of truck overload detection and alarm device

technical field

The utility model relates to a novel truck overload detection and alarm device, which belongs to the field of automobile electric appliances.

Background technique

Vehicle overloading refers to exceeding the specified load capacity of the vehicle. Usually, overloading of trucks will not only shorten the service life of the vehicle itself, damage the road surface, but also affect the stability, flexibility and safety of the car, and seriously cause traffic accidents. Although there are various disadvantages of overloading cars, the economic interests behind them make some people ignore the dangers and traffic regulations. The overloading is serious, which has buried hidden dangers for traffic safety.

Contents of the invention

The purpose of the utility model is to solve the above problems and provide a novel truck overload detection and alarm device. It is achieved through the following technical solutions:

A new type of overload detection and alarm device for trucks, including a power module, a strain gauge, an alarm system, and a single-chip microcomputer, a display, a data memory, and a control ECU. The input end of the strain gauge is connected to the power module through a wire, and the output end is connected to the single-chip microcomputer. , the display and the data memory are connected to the single-chip microcomputer, the display is connected to the alarm system, the input end of the control ECU is connected to the single-chip microcomputer, the output end is connected to the engine ignition system, the main part of the device is installed on the upper part of the instrument panel, and the strain gauge Attached to the upper and lower sides of the leaf spring respectively.

The utility model compares the advantages of the prior art:

1. The utility model can effectively detect the vehicle load and send an alarm signal when the load exceeds a certain range, and at the same time prevent the engine ignition system from working, thereby preventing overloaded transportation and reducing traffic accidents.

2. The utility model uses strain gauges to accurately measure the deformation of the leaf spring and then process and obtain the load information of the truck

3. The utility model adopts a single-chip microcomputer, a display, a data memory and a control ECU, which is beneficial to the development of the automobile to a complete electronic age.

Description of drawings

Fig. 1 is a schematic layout diagram of the automobile brake monitoring device described in the present invention.

Detailed ways

1-power supply module; 2-strain gauge; 3-single-chip microcomputer; 4-display; 5-alarm system; 6-data memory; 7-control ECU; 8-engine ignition system.

Below in conjunction with embodiment accompanying drawing, the utility model is described further.

As shown in Figure 1, the truck overload detection and alarm device shown in the utility model includes a power module 1, a strain gauge 2, a single-chip microcomputer 3, a display 4, an alarm system 5, a data memory 6, and a control ECU7. The single-chip microcomputer 2 transmits the leaf spring deformation signal to the single-chip microcomputer 3, and the single-chip microcomputer 3 converts the deformation signal into a digital signal through A/D, and then processes it into a corresponding load signal, and utilizes the display 4 to display information such as the load of the truck, which is conducive to driving The operator understands the loading capacity of the truck, and stores this signal through the data memory 3 to facilitate future inspection and maintenance work. When the load exceeds a certain range, an alarm signal is sent by the alarm system 5, and the power-off signal is sent to the control ECU by the single-chip microcomputer, and the control ECU stops the ignition of the engine by controlling the engine ignition system to prevent overloaded transportation.
