Automatic control device for inflator pump installed on vehicle

Abstract

The invention discloses an automatic control device for an inflator pump installed on a vehicle. The automatic control device comprises a shell, an intelligent touch screen is embedded into the centerof the top end face of the shell, a Max7221 nixie tube is embedded into the center of the intelligent touch screen and electrically connected with the intelligent touch screen, a MCU microcontrolleris arranged in an inner cavity of the shell, the microcontroller is electrically connected with a self-locking relay and an RF receiver, the RF receiver is connected with an RF transmitter through wireless signals, the RF transmitter is electrically connected with a tire pressure sensor, the RF receiver is electrically connected with an A / D converter, and the A / D converter is electrically connected with the Max7221 nixie tube. According to the automatic control device for the inflator pump installed on the vehicle, the tire pressure can be monitored in real time, the rated tire pressure valuecan be set through the intelligent touch screen and displayed on the intelligent touch screen in a numeric mode, a circuit can be automatically controlled to be disconnected, the tire pressure is prevented from being too high, and the device is simple and practical.

Description

Technical field [0001] The invention relates to the technical field of automation-related applications, in particular to an automatic control device for an onboard air pump. Background technique [0002] Vehicle air pumps are also called inflators, air pumps, and vehicle-mounted air pumps, which work through the operation of an internal motor. When pumping air, the valve of the communicating device is opened by atmospheric pressure, and the gas enters the cylinder. When pumping into the tire, the valve is closed by the air pressure in the cylinder, and the gas enters the tire. We know that the existing simple inflation The pump does not have a control device that automatically controls the closing of the air pump according to the standard tire pressure. This cannot make the pressure of the two front tires or the pressure of the two rear tires the same. Although some cars have an intelligent detection system to detect the tire pressure, When the tire pressure reaches the same lev...

Problems solved by technology

When pumping air, the valve of the connector is opened by the atmospheric pressure, and the gas enters the cylinder. When pumping air into the tire, the valve is closed by the air pressure in the cylinder, and the gas enters the tire. We know that the existing simple inflation The pump does not have a control device that automatically controls the shutdown of the air pump according to the standard tire pressure, so that the pressure of the two front tires or the pressure of the two rear tires cannot be the same. Although some cars have an intelligent detection system to detect the tire pressure, but When the tire pressure reaches the same level, the air pump cannot be turned off in time, which is very inconvenient. Therefore, an automatic control device for the on-board air pump is designed and produced here to facilitate repeated use.
