Description

A kind of processing method for elevator shaft internet of things equipment lradio communication failure

Technical field

It is more particularly to a kind of to be used for elevator shaft internet of things equipment channel radio the present invention relates to elevator internet of things field Believe the processing method of failure.

Technical background

In elevator shaft wiring environment, live spatial dimension is limited and wiring cable there are multiple voltage, has strong Electricity also has light current.Internet of things equipment for elevator with being often subject to dense ionization interference during server communication, do by radio frequency Disturb, in substantial amounts of wireless communication data transmission process, since elevator internet of things equipment can take public network bands, service provider Long-time can be taken, while the internet of things equipment implementation of the continual transmission of data is kicked out of frequency band reduction wireless data signal and passed Defeated congestion phenomenon.

, forever all can be there are wireless data transmit power factor for equipment and circuit in wireless data transmission is carried out Interference, this is inevitable, for the requirement that start uses that can arbitrarily shut down of the corresponding product for civilian use, their processing Stringency not may require that ultimate attainment, but for the application of corresponding industry control, some accumulation of interference, in the accumulation of time, is penetrated Frequency interference will become a kind of very intractable thing, its presence is inevitable, can not be escaped.Its presence how is controlled to limit Degree and scope, are the problems that concern is had in internet of things equipment design, otherwise may in the scene that nobody stands fast at, equipment Because interference, occur exception at any time, and produce the situation that internet of things equipment is unable to long-term stable operation.In the present of information age My god, particularly the internet of things equipment for special equipment occur the problem of communication disruption will to the safety belt of elevator come it is serious Security risk；In economic aspect, it is unfavorable for the popularization of the Internet of Things equipment for elevator.

The content of the invention

The problem of present invention is in order to overcome above-mentioned internet of things equipment and server communication that interruption often occurs, there is provided a kind of Processing method for elevator shaft internet of things equipment lradio communication failure includes statistics transmission data unit time error code quantity Program compiling method, protocol layer fracture defect processing routine Compilation Method, circuit communication disconnect exception handles Compilation Method； The numerical value that the statistics transmission data unit time number of bit errors amount program compiling method counts is more than the standard value of setting, uses The circuit communication disconnects exception handles Compilation Method processing wireless telecommunications failure；The statistics transmission data unit time The numerical value that number of bit errors amount program compiling method counts is less than or equal to the standard value of setting, using the protocol layer fracture defect Processing routine Compilation Method handles wireless telecommunications failure.

It is described statistics transmission data unit time number of bit errors amount program compiling method the step of be：

(1) pseudo-random sequence is produced, as test data；

(2) test initialization, including initialization error code counter and loopback are tested required detection letter in wireless communication system Road；

(3) cycle tests is sent, for by the required detection channel that has been looped back, and pseudo-random sequence to be continued one Fix time；(4) cycle tests is received, for receiving original Pseudo random test sequences and result test being received from loop back channel Sequence, and lasting and step (3) equal length time；

(5) cycle tests is compared, for continuously by the result cycle tests received and original Pseudo random test sequences Carry out the comparison by bit；

(6) error code result counts, and for the value according to the error code counter after the completion of the testing time, calculates corresponding biography Transmission of data unit interval error code quantity.

The transmission data unit time error code quantity calculated with the above method is less than given standard value, using described Protocol layer fracture defect processing routine Compilation Method handles wireless telecommunications failure.

Further, the protocol layer fracture defect processing routine Compilation Method step includes：

1）Signal trace：Integrality judgement is carried out to the prefix and suffix of 2G networks networking signaling protocol；

2）Operating system task is segmented：The field of the prefix and suffix is mismatched with criteria field, is then shut off using The networking control program of the prefix and suffix, starts new networking control program；

3）Operating system node judges：Judge the storage address of the gateway program running memory of the closing；Opened described Dynamic new networking control program is loaded into the storage address；

4）Node label is found：By the suspension flag bit for closing gateway program and the mark for starting new networking control program Will position writes the control program of new startup, judges to provide inquiry foundation for next suspension；

5）Operating system releases site：Remove the running memory space of the gateway program of the closing；

6）.socket reconnection：With the network progress reconnection of telephone network services operation centre.

The programmed method of the protocol layer fracture processing routine, solves and takes network frequency for a long time by wireless communication data Band and there is the problem of network interruption, the program of such a method compiling performs, ensure that the unimpeded of network, high-level layer repeatedly Realize the transmission of complete long-time data flow in face.

Further, data unit time error code quantity is transmitted not less than given standard value, using the circuit communication Disconnect exception handles Compilation Method processing wireless telecommunications failure.Such a circuit communication disconnects exception handles Compilation Method Comprise the following steps：

1）Detect that protocol layer disconnects and communication module circuitry directly shuts down while exists；

2）The 4V Switching Power Supplies of the whole system of radio circuit are controlled to close；

3）Delay procedure is performed, the 4V Switching Power Supplies of the whole system of radio circuit are opened after delay 10S；

4）System reconnects agreement；

5）Telecommunication circuit reconnects.

The circuit communication disconnects the step 1 of exception handles Compilation Method）Set two kinds of factors as judgement according to According to the Switching Power Supply for reducing 4V malfunctions, and causes the stand-by period of communicating interrupt；Step 3）With step 4）The radio frequency that will build up on is done Disturb and discharged, make circuit and program recovery in original anti-interference section.Circuit communication disconnects failure and is handled, into one Interruption often occurs with server communication in the intelligent internet of things equipment for solving the problems, such as to be used for elevator of step, for making for equipment With and promote, manufactured big advantage.

The invention compared with the prior art, have the advantage that for：
