Wireless interactive system of pull type caravan

Abstract

The invention discloses a wireless interactive system of a pull type caravan. The system comprises a steering circuit, a sensor response module, a wireless transmission module and a light execution module, wherein the sensor response module comprises a pressure sensor, a current sensor and an engine rotating speed sensor; the input end of the pressure sensor is connected to a brake pedal through aspring; the input end of the current sensor is connected to the steering circuit; the wireless transmission module comprises a transmitting end and a receiving end; the output ends of the pressure sensor, the current sensor and the engine speed sensor are all in signal connection with the transmitting end, and the receiving end is simultaneously connected with a brake lamp, a left steering lamp and a right steering lamp. The system can realize synchronous work of the tractor and the caravan lamp, and is capable of quickly determining a fault area when the interaction system fails, thereby improving the detection and maintenance efficiency and effectively solving the safety problem in the aspect of light signal connection of the pull type caravan; and the system has a wide development prospect.

Description

technical field [0001] The invention relates to a wireless interactive system for a towed caravan, which belongs to the field of automobiles. Background technique [0002] With the improvement of people's living consumption level, self-driving tours are favored, and thus trailer-type RVs have entered the lives of Chinese people. [0003] At present, when a trailer-type caravan is turning and braking, the movement of the rear lights of the caravan needs to be consistent with the action of the taillights of the tractor. There is asynchrony between the lights of the tractor and the lights of the RV when braking, and the working environment of the wire at the connection between the tractor and the RV is harsh, and it is prone to breakage. The wires transmit signals across vehicles, and the lights of the RV are prone to failure, posing a safety hazard , There are a lot of furniture inside the caravan, the layout of the wires is complicated, and the maintenance is inconvenient. ...

[0003] At present, when a trailer-type caravan is turning and braking, the movement of the rear lights of the caravan needs to be consistent with the action of the taillights of the tractor. There is asynchrony between the lights of the tractor and the lights of the RV when braking, and the working environment of the wire at the connection between the tractor and the RV is harsh, and it is prone to breakage. The wires transmit signals across vehicles, and the lights of the RV are prone to failure, posing a safety hazard , there are a lot of furniture inside the caravan, the layout of the wires is complicated, and the maintenance is not convenient

Moreover, when a fault exists, it is difficult to check the fault and it is extremely inconvenient to use
