Embodiment
To describe the technology contents of the present invention, the objects and the effects in detail, below in conjunction with embodiment and coordinate attached
Figure is explained.
As shown in Figure 1 to Figure 3, the present invention provides a kind of method for handling radio POS terminal failure, including at least following step
Suddenly：
S1：Radio POS terminal is successively monitored according to osi model, and collects information, to determine the failure of radio POS terminal
Type, and show Recovery Options；
S2：Search for and adhere to base station nearby one by one, and pressure test communication success rate, determine optimum base station；
S3：By the serial ports external radio development board of radio POS terminal, communication daily record is obtained, is positioned.
Specifically, from OSI (Open System Interconnection, open system interconnection.International standardization group
Knit (ISO) and formulated osi model, the standard of the different computers interconnections of the model definition, is design and description computer network
The basic framework of communication) communication five layer protocols in successively monitor.Relevant parameter in physical layer is monitored first.
Physical layer includes communication module AT instruction monitoring, monitors the interactive information of POS and communication module, if AT instructions can
Normally to receive and dispatch, and whether instruction returns normally.If return is abnormal, solution can be judged by this：Communication
Module interface hardware damage solves, it is necessary to repair and change module.
The communication signal of radio POS terminal is a measurement index.If communication signal is less than 8, then very maximum probability goes out
Now dialing failure, communicate the high problem of packet loss.Therefore POS interface displays：Signal is too low, is moved to spacious place or changes antenna
Solve.
Whether radio POS terminal registers base station, according to CGREG information, can interpolate that equipment whether with base station attachment into
Work(, such as unsuccessful, the possible arrearage of SIM address cards causes base station refusal attachment, specifically as shown in Figure 2.
Secondly for the data link layer of OSI communications protocol, in a specific embodiment, ppp link is divided into LCP associations
View, CHAP/PAP certifications, IPCP agreements etc..Debug options are added in PPP.conf configuration files, you can open debugging mould
Formula, link Debugging message is toward inserting in the file specified.In case of a fault, it is possible to which, because user name, code error is led
CHAP/PAP authentification failures are caused, now can give one solution of upper-layer user by log (daily record) analyses.
Finally for OSI network layer datas, in a specific embodiment, tcpdump program monitoring POS tcp are used
Interaction data.Log is preserved to specific file.POS programs analyze this log, if sync synchronous packages are sent always, illustrate and clothes
Business device can not connect, and carry out malfunction coefficient.Analysis retransmits packet always if program causes exchange hour to be grown, then aobvious
Show " retransmitting overabundance of data, network is poor ".
For step S2, according to radio POS terminal neighbor base station, adhere to one by one, and pressure test communication success rate, draw
Optimum base station.
Specifically, in communication failure region, scan and obtain neighbor base station list.General area base station has 6, selects letter
Make an uproar than at -75db base station (i.e. target BS), being locked one by one, and the interaction success rate of pressure test equipment and base station
(such as PPP dialing success rates or TCP interaction success rate), statistical result simultaneously arranges.Solve problem to be interim, be first temporarily locked in most
Excellent base station, treat that operator's feedback rectification is completed, unlock, as shown in Figure 3.
Finally, in step s3, solves orientation problem by POS serial ports external radios development board.
Specifically, external radio communication development board is connected on POS, and POS is communicated using external radio module, can be with
Effectively solve POS and tear key loss problem caused by machine open, cause failure can not get the trace information of bottom.
When the physical serial interface that AT instruction repertories use is opening external modem, it is altered to use with external modem
Physical serial interface；
The physical serial interface used when PPP dials is altered to use with external modem when external modem is opened
Physical serial interface；
When GPRS multiplexings GsmMuxd is opening external modem, the thing used with external modem is altered to
Manage serial ports.
After above-mentioned each programing change associated with physical serial interface, you can use external modem functions, and capture IC
The log of communication chip level, positioned for subsequent analysis.
To sum up, the present invention at least possesses following beneficial effect：
This method can quickly position oneself problem, the efficient self-regeneration communication failure problems of POS.Eliminate Communication Engineering
It is time and human cost needed for the positioning of teacher scene, both fast and economical.Program have accumulated the solution for the problem of having found,
In the case of POS can not be repaired automatically, program, which can be shown, instructs major area locality customer service FAE to carry out associative operation to correct
Problem, it is quick to instruct, it need not check that document can solve problem in the case where local FAE is unfamiliar with communication knowledge.
Accordingly, the present invention also provides a kind of system for handling radio POS terminal failure, including：
Monitoring module, for successively monitoring radio POS terminal according to osi model, and information is collected, to determine wireless POS
The fault type of terminal, and show Recovery Options；
Base station module, for searching for and adhering to one by one base station nearby, and pressure test communication success rate, determine optimal base
Stand；
Locating module, for the serial ports external radio development board by radio POS terminal, communication daily record is obtained, is determined
Position.
Wherein, the monitoring module is according to osi model, monitors communication module AT instructions in physical layer, radio POS terminal
With communication module interactive information, the communication signal intensity of radio POS terminal and base station login status information, wherein
When detecting that communication module AT instructions return to abnormal, the interface hardware damage of display communication module；
When communication signal intensity is less than 8, display is moved to spacious place or changes antenna；
When it is to register base station to monitor registration status information, and detecting the failure of radio POS terminal attached base station
Afterwards, when and detecting SIM card, display SIM address card arrearages cause base station refusal attachment.
Wherein, the base station module is scanned and obtains neighbor base station list in radio POS terminal communication failure region；
Base station of the signal to noise ratio in list more than -75db is set into target BS, and locked one by one；
The interaction success rate of pressure test radio POS terminal and target BS, obtain statistical result and sort；
The maximum target BS of interaction success rate is set to optimum base station.
The serial ports external radio development board that the locating module passes through radio POS terminal；
When opening external modem, the physical serial interface that AT instructions use is changed to the physical serial interface for external modem；
When opening external modem, the physical serial interface that PPP dialing uses is changed to the physical serial interface for external modem；
When opening external modem, the GsmMuxd physical serial interfaces of GPRS multiplexings are changed to for external modem's
