Engineering vehicle overspeed stop device and control method thereof

Abstract

The invention discloses an engineering vehicle overspeed stop device and a control method thereof. The device consists of a controller, an electronic clock, an oil supply solenoid valve, a buzzer warning circuit and a wheel speed sensor. The method comprises the following steps: detecting the electronic clock by using an electronic system to judge an engineering vehicle runs in the day or in the night, setting different highest speed limit values and common speed limit values, and periodically detecting a speed signal output by the wheel speed sensor currently in a periodical interruption mode; and converting the speed signal into the current speed signal, comparing whether the speed signal is greater than the preset highest speed limit value, setting the frequency of exceeding the common speed limits, and deciding whether a buzzer gives an alarm and the oil supply solenoid valve is opened. The engineering vehicle overspeed stop device is simple in circuit structure, good in real-time property, accurate in measurement and lower in cost, the safety of engineering vehicles can be improved, and the safety of human life and property is guaranteed.

Description

technical field [0001] The invention belongs to a vehicle overspeed stop and a control method thereof, in particular to a large construction vehicle overspeed stop device and a control method. Background technique [0002] In recent years, the number of cars has increased rapidly, and vehicle safety has become the most concerned issue, especially for large-scale construction vehicles. Due to the long-term operation of the construction vehicle driver, it is easy to cause fatigue, and it is very likely to drive at high speed. There are often collision and crushing incidents. The famous provincial newspaper "Yangtze Evening News" in Jiangsu Province reported on May 15, 2012: The collision between a large truck and a motorcycle, The 30-year-old teacher of Nanfang Polytechnic University who was riding a bicycle died; "Modern Express" reported on April 26, 2012: The engineering vehicle turned right and ran over the young woman who was riding the bicycle. There are countless such ...

Problems solved by technology

However, the overspeed arresting devices for construction vehicles commonly used in the market are overspeed control by mechanical devices. For example, the patent No. 200320100925.0 is a purely mechanical vehicle speed limiting device. The device is based on a purely mechanical principle and the manufacturing cost is relatively high.
