Problems solved by technology

However, because the alcohol tester often breaks down due to various reasons during use, and as the use time increases, its stability and test accuracy become worse and worse, it is often necessary to send the alcohol tester to the production of the alcohol tester Calibration by the manufacturer, this process often wastes a lot of time and money
At present, the alcohol tester does not have the function of fault self-diagnosis, nor does it have the function of remote diagnosis.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and examples of implementation.

[0024] refer to figure 1 , figure 2 and image 3 , to illustrate the process of remote fault diagnosis of alcohol tester with fault self-diagnosis program and GPRS module, figure 1 Including an alcohol tester 1 with a fault self-inspection program 2 and a GPRS module 3 and a remote monitoring center 7 as a server; when carrying out the breath alcohol content test, first the subject holds the mouth of the exhalation pipe with his mouth, and blows it evenly and continuously. Inflate for 6-10 seconds, when "stop" is displayed on the screen, the air sampling is successful, otherwise it will be re-sampled. After the exhalation is successful, the exhaled sample of the subject first enters the fuel cell sensor module 16 through the inhalation device 15, and the obtained electrical signal enters the information preprocessing module 17, and af...

Abstract

The invention discloses remote fault diagnosis method and system for an alcohol tester based on a GPRS. A CPU module in the alcohol tester is connected with an SIM card through a GPRS module which is connected with an antenna. The remote fault diagnosis method comprises the steps of: checking working states of all modules in the tester through a fault self-checking program of the tester; transmitting the check result of the fault self-checking program to a monitoring center of a tester manufacturer through the GPRS module; and knowing the working state of the tester according to the check result for fault recovery. The monitoring center has a favorable human-machine interface, can directly reflect the working state information of relevant equipment of the tester, better monitor the remotealcohol tester, carry out the statistical analysis on the received state information of the equipment of the tester, and be applied to the following service plan system. The tester also has the GPS positioning function, positions the tester of a service point through a positioning satellite and provides telephone or visiting service for the fault which can not be remotely recovered.

Description

technical field [0001] The invention relates to a method and a system for remote fault diagnosis of an alcohol tester, in particular to a method and a system for a remote fault diagnosis of an alcohol tester based on GPRS. Background technique [0002] At present, frequent traffic accidents caused by drunk driving have caused great harm to the safety of people's lives and property. Using an alcohol tester to detect whether a driver is drunk and driving can effectively control the driver's drunk driving, which is also after a traffic accident. One of the important measures of investigation and evidence collection. However, because the alcohol tester often breaks down due to various reasons during use, and as the use time increases, its stability and test accuracy become worse and worse, it is often necessary to send the alcohol tester to the production of the alcohol tester Manufacturers perform calibration, a process that often wastes a lot of time and money. At present, t...
