Problems solved by technology

[0005] With the inventor's further research, the inventor found that the above technical solution has the following disadvantages: first, the traffic on the road is relatively busy, and the frequent friction loss between the trapezoidal wedge and the inclined shoulder is likely to affect the accuracy and use. ; Second, in the existing scheme, if the friction loss is to be alleviated, a lubricant must be used, and the use of a lubricant will lead to shortcomings such as unstable weighing

Embodiment Construction

[0025] Figure 1 to Figure 3 Shown is the preferred embodiment for implementing the present invention.

[0026] The working principle of the present invention is as follows:

[0027] 1. This technical solution adopts a relatively simple and stable weight measurement method to judge the weight of the vehicle, and transmit the judgment results to the control circuit through different electrical signals, and the control circuit makes judgments on subsequent actions. If the weight of the vehicle Within the set allowable range, the vehicle will be allowed to pass, otherwise, the actuator will be triggered to prevent the vehicle from passing; when the vehicle that is not allowed to pass withdraws from the road section, the actuator will return to its original state and the road will be used normally.

[0028] 2. In judging the vehicle’s overweight weight, the present invention is based on Hooke’s theorem, and the elastic device can drop to different heights with the weight of the v...

Abstract

The invention discloses an intelligent road-blocking method for vehicle weight limitation. The method comprises a weight judging step, a signal transmission step and an execution step. The weight judging step refers to driving a vehicle to a pressure plate with a travel switch contact so as to judge the weight of the vehicle; the signal transmission step refers to transmitting the judging result to a circuit connected with a drive motor and a motor power supply in a switch touch mode so as to form different electrical signal circuits; and the execution step refers to using the different electrical signal circuits to drive a barrier bar by the drive motor to carry out the action of blocking or releasing. With the method, the weight-limiting performance is steady, the measurement is accurate, the problem of blocking the over-weight vehicles and releasing the vehicles meeting the weight limitation requirement in a weight-limiting section of road can be solved conveniently, thus, the section of road is protected, and the aims of prolonging the service life of the road and preventing road accidents are realized.

Description

technical field [0001] The invention relates to the field of road weight limit protection, in particular to an intelligent roadblock method for vehicle weight limit. Background technique [0002] In order to ensure the normal use of the road and not affect the practical life of the road, the current relevant research and effective measures are still limited to two basic methods: height limit or width limit. The above methods have not designed and produced a set of effective protection methods based on the real reason that affects the service life of the road-the load bearing of the road. [0003] Starting from the real reason that affects the service life of the road—the weight of the road, the inventor conducted in-depth research in the technical field of road weight limit protection, and filed a Chinese patent application with the application number 201020617457.4 on November 19, 2010. A weight-limiting intelligent roadblock device based on the vehicle's own weight is pro...
