2). operating system task segmentation: the field of described prefix and suffix is not mated with criteria field, then close the networking control program using described prefix and suffix, start new networking control program;

3). operating system node judges: the storage address judging the gateway program running memory of described closedown; Networking control program new for described startup is loaded into described storage address;

4). find node label: the control program flag bit of networking control program new with startup for the suspension flag bit of closing gateway program being write new startup, for next suspension judges to provide inquiry foundation;

5). operating system releases site: the running memory space of removing the gateway program of described closedown;

6) .socket reconnects: reconnect with telephone network services operation centre network.

The programmed method of described protocol layer fracture handling procedure, solve and take network bands for a long time by wireless communication data and occur the problem of network interruption, the program of this kind of method compiling, performs repeatedly, ensure that the unimpeded of network, high-level aspect realizes the transmission of long-time data flow completely.

Further, transmission data unit time error code quantity is not less than given standard value, adopts described circuit communication open failure handling procedure Compilation Method process wireless telecommunications fault.This kind of circuit communication open failure handling procedure Compilation Method comprises the following steps:

1). detect that protocol layer disconnects and communication module circuit directly shuts down and exists simultaneously;

2). the 4V Switching Power Supply controlling the whole system of radio circuit is closed;

3). perform delay procedure, after postponing 10S, open the 4V Switching Power Supply of the whole system of radio circuit;

4). system reconnects agreement;

5). telecommunication circuit reconnects.

The step 1) of described circuit communication open failure handling procedure Compilation Method arranges two kinds of factors as the foundation judged, reduces the Switching Power Supply misoperation of 4V, causes the stand-by period of communicating interrupt; The radio frequency interference of accumulation discharges by step 3) and step 4), makes circuit and program recovery in original anti-interference interval.Circuit communication open failure is processed, and further the solution of intelligence is used for the problem that the internet of things equipment of elevator and server communication often there will be interruption, and using and promoting for equipment, has manufactured huge advantage.

This invention is compared with prior art, and the beneficial effect had is:
