Traffic machine system and self-checking method thereof

Abstract

The invention discloses a traffic machine system and a self-checking method thereof. The system has the advantages of being convenient for operation and fast in detection, the self-checking problem of the traffic machine is solved; the technical scheme is as follows: judging whether a feedback signal is received within the required time by sending an AT instruction, thereby determining a fault type and directly displaying the fault on the traffic machine. The operation can be performed through an upper computer, so that the control convenience degree is improved.

Description

technical field [0001] The invention relates to the technical field of telephone communication, in particular to a telephone system and a self-checking method thereof. Background technique [0002] Global System for Mobile Communication (GSM), also known as GSM, is currently the most widely used mobile phone standard. More than 1 billion people in more than 200 countries and regions around the world are using GSM phones. [0003] GSM belongs to the 2nd generation (2G) cellular mobile communication technology. Analog cellular technology is called the first generation of mobile communication technology, and broadband CDMA technology is called the third generation of mobile communication technology, namely 3G. [0004] The GSM system is mainly composed of four parts: Mobile Station (MS), Mobile Network Subsystem (NSS), Base Station Subsystem (BSS) and Operation Support Subsystem (OSS). [0005] At present, communication line failures often occur in the communication process ...

AI Technical Summary

Problems solved by technology

[0005] At present, communication line failures often occur in the communication process of the telephone, and the staff cannot effectively know which line is faulty. On the one hand, the existing telephone is connected to the telephone network, and on the other hand, it can also be connected to the PC and / or the host computer. For communication, the PC can perform network communication, can be directly connected to the Internet network, and can call applications and use cloud servers

The telephone cannot communicate. This fault may be caused by a local communication fault or an external network problem. The user cannot effectively judge the source or type of the fault, so it is necessary to study the detection direction of the fault.
