The invention discloses a vehicle-mounted global position system (GPS) terminal for preventing drunk driving. The terminal consists of an alcohol gas concentration detector, and a vehicle-mounted positioning GPS terminal; the alcohol gas concentration detector consists of a peripheral circuit, an automatic voltage regulation (AVR) singlechip and operation facilities; the peripheral circuit consists of an alcohol concentration detection sensor, a thermoelectric stimulated current infrared sensor, an expired gas detection sensor, a filtering and analog-digital (AD) detection circuit, amplification and filtering circuits, a camera and driving electronic circuit, and a reshaping and comparison circuit; the operation facilities consist of a starting key, a red / green light-emitting diode (LED) lamp and a buzzer which are connected with the AVR singlechip respectively; the GPS positioning terminal is connected with an oil circuit relay and a circuit relay; and monitoring centers wirelessly communicate with the GPS positioning terminal, and the 3rd generation telecommunication (3G), general packet radio service (GPRS) and code division multiple access (CDMA) transmission modules; and in the vehicle-mounted GPS terminal for preventing drunk driving, a large scale integrated circuit, and a modular design are adopted, so that sample introduction of tested gas and data acquisition and processing are realized. Therefore, the interference of gasoline, perfume and the like can be effectively eliminated due to sample introduction, the detection result is accurate and can be obtained quickly, terminal equipment has high expansibility, and the interfaces are abundant.
Description
Technical field: [0001] The invention relates to a vehicle-mounted GPS terminal, in particular to a network-based vehicle-mounted GPS terminal with information display for detecting alcohol concentration in exhaled gas. Background technique: [0002] The development potential of China's GPS positioning and navigation system market is very huge. In the next few years, China will become the world's largest vehicle GPS market. mature, vehicle positioning and navigation systems will be more widely accepted by consumers. At present, there are many types of GPS products in my country, and the products that can be seen in China can be roughly classified into several categories: PDA comes with satellite module + map + car bracket (optional) + external antenna module; PDA mobile phone + Bluetooth or wired Satellite module + map + bracket + car rush; notebook + satellite module + map + bracket + power converter; professional positioning and navigator. The quality of these products is...
