Embodiment Construction

[0027] The embodiments involved in the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, a wireless speed limiting system for a passenger car includes a road sign transmitter and an on-board receiver. The road sign transmitter is installed along the way of the bus, and the on-board receiver is installed in the cab of the bus; the road sign transmitter and the on-board receiver are connected through a wireless network. communication connection.

[0029] The road sign transmitter includes a keyboard control unit, a processor unit, a display unit, a storage unit, a wireless transmission unit and a solar power supply unit; the keyboard control unit sets the speed upper limit values ​​of different models and saves them in the storage unit; the display unit displays the speed limits of different models. The upper limit of speed; the processor unit coordinates the work of each unit, and send...

Abstract

The invention provides a wireless speed-limiting system for a passenger car, which includes a road sign transmitter and a vehicle-mounted receiver. Make a communication connection. Based on wireless technology and single-chip microcomputer control technology, the present invention realizes a voice alarm prompt for overspeed and cuts off the oil circuit of the passenger car to achieve the speed limit. It has the characteristics of energy saving and environmental protection. It has simple structure, small size, low cost, low system power consumption, high detection accuracy, sensitive response, good stability and reliability, and can be expanded. It is suitable for speeding problems of different models, and can also be widely used in car chasing, car anti-theft, information transmission of violations and traffic restriction broadcasting, etc.

Description

technical field [0001] The invention relates to the technical field of logistics transportation safety, in particular to a wireless speed limiting system for passenger cars. Background technique [0002] Speeding vehicles are prone to traffic accidents, and once an accident occurs in a passenger car, it is very easy to induce serious vicious accidents involving mass death and mass injury, which has brought extremely heavy losses and injuries to the country and the masses. At present, Germany's Siemens has developed a road speed limit sign recognition device, which uses a camera to identify the speed limit sign ahead, and will issue a warning when the driving speed is faster than the speed limit. Use this device in principle to achieve the purpose of early warning speed limit, but this device is often affected by changes in the external environment when identifying speed limit signs. Especially in cloudy and rainy days, the device just cannot identify accurately under the si...
