And alarming according to the alarming information, and reporting the alarming information based on the mqtt protocol.
In the following, the technical scheme of the present invention is explained by a specific embodiment, step 1, the system powers on the 4G and 5G embedded modules, and the SIM switch of the subscriber identity module card is turned off by default, and after the program starts to be executed, the system turns on any embedded module, for example, the embedded module and the SIM switch can be numbered, so that the default number embedded module and the SIM switch are turned on, and the default number embedded module and the default number SIM switch can be defined as the first number embedded module and the default number corresponding embedded module and SIM switch.
And 2, after power-on, the electronic equipment is communicated with the embedded module, the electronic equipment sends an instruction to the embedded module through a serial port to determine the type of the embedded module, and after the electronic equipment determines the type of the embedded module, the electronic equipment performs signal inspection and internet dialing in a corresponding mode of the embedded module.
And 3, when the electronic equipment sends an instruction to the embedded module through the serial port to perform signal checking signal is poor, the embedded module fails to dial on the internet or the network is poor, the current embedded module is used continuously, but the next SIM card is switched, and the internet dialing is repeated. After all SIM cards of the current embedded module fail to try, the current embedded module can be switched for 5 times, if the current embedded module continuously tries to dial with all SIM cards for 5 times, the current embedded module still cannot be connected with the network, and the next embedded module is switched at the moment.
And 4, switching to the next embedded module, and repeating the processes in the step 2 and the step 3 until switching to the last embedded module.
And 5, after all the embedded modules are failed to be switched, switching for multiple rounds, namely repeating the processes in the steps 2-4, wherein the switching round can be tentatively set for 5 times, when the embedded modules are not networked after switching for 5 rounds, the electronic equipment records a log and gives an alarm, the current algorithm is exited, and related data is sent to the cloud platform for monitoring through the mqtt protocol after successful networking.
Step 6, the intelligent matching switching algorithm is further described in detail below.
Step 7, the electronic device starts to execute the algorithm, firstly reads two parameters required by the electronic device program, the first is the name of the network card, the first is whether the network driver of the electronic device is ready, if the network driver is ready, the correct name of the network card is transmitted, and the second is the parameter of the modification mode of the routing table, so that the specific operation mode of the routing table of the electronic device is determined. The two parameters are transmitted by a caller calling the algorithm, the algorithm reserves a parameter transmission interface for the caller to transmit, the network card is a necessary parameter, the algorithm is exited when the parameter is not transmitted or transmitted in error, the route table modification mode is a selected parameter, and the parameter can be modified according to a default operation mode if the parameter is not transmitted or transmitted in error.
And 8, after receiving the parameters, the electronic equipment firstly executes the algorithm to judge the network card, if the network card does not exist, records error information to a log and sends out alarm information, the electronic equipment receives the error information, the current algorithm exits, and the network card is determined to exist.
Step 9, the electronic device executes the algorithm to start counting the serial port number of the electronic device, and records the serial port number (in the invention, the electronic device and the embedded module adopt serial port communication mode, and one device may have multiple peripheral devices to use serial port communication).
And 10, counting the serial number, starting from the serial port with the lowest serial number, opening the serial port, switching to open the next serial port if the serial port fails to be opened, recording error information to a log and sending alarm information if all the serial ports are not opened, receiving by the electronic equipment, and exiting the current algorithm.
And 11, after the serial port is successfully opened, the electronic equipment executes the algorithm to send an AT instruction to the embedded modules through the serial port, wherein the AT is a detection command, and all the embedded modules can uniformly reply to OK after receiving the detection command.
In step 12, if the "AT" is sent and the embedded module is not recovered, the method is continuously sent for five times, and if the "AT" is not recovered for five times, the next embedded module is switched (because the embedded module is not recovered and is irrelevant to the SIM card, the SIM card is not required to be switched), and after the embedded module is switched, the electronic device executes the algorithm to return to the process described in step 9 to start execution. Until the embedded module fails to switch for 5 rounds (record error information to log and send out alarm information, received by the electronic device, current algorithm exits) or successfully replies "OK".
And 13, after the AT command is sent and the embedded module replies OK, the electronic equipment executes the algorithm and sends the ATI command to the embedded module through the serial port for inquiring the product information of the embedded module, wherein the information is defined by manufacturers, but the information contains the name of the manufacturer of the module and the model of the embedded module and is used for distinguishing different embedded modules.
Step 14, if the "ATI" is sent, the embedded module is not replied, it is sent five times continuously, if the "ATI" is not replied five times continuously, then the next embedded module is switched (because the embedded module is not replied and is not related to the SIM card, the SIM card is not required to be switched), after the embedded module is switched, the electronic device executes the algorithm to return to the procedure described in step 9 again. Until the embedded module is switched for 5 rounds, the error information is recorded to the log and the alarm information is sent out, the current algorithm is received by the electronic equipment, and the embedded module information is successfully recovered.
Step 15, each embedded module has own dialing mode, basically different, after the information of the embedded module is recovered, different types of the embedded modules are classified according to the name of each manufacturer and the different types of the embedded modules, wherein the embedded modules in the same dialing mode are classified into one type, each type is arranged according to the sequence number, for example, the embedded modules are classified into A, B, C, D types in advance in a program according to the name, and after the current embedded module is identified, the embedded modules are waited for to dial according to the corresponding dialing mode.
And step 16, after the embedded module is identified, recording the model number of the embedded module into the MODE file.
Step 17, after determining the type of the embedded module, inquiring whether the SIM card exists according to a corresponding mode, wherein the embedded module is currently generally an "at+cpin.
And step 18, after sending the command for inquiring the existence of the SIM card, if the command for inquiring the existence is not returned, detecting for 5 times, executing the algorithm by the electronic equipment to switch the SIM card after 5 times, and repeating the detection command.
Step 19, until all SIM cards are switched 5 times or detected. If the SIM card is still not found after switching all the SIM cards 5, switching the embedded module, and executing the algorithm by the electronic equipment, returning to the process in the step 9 again to start execution.
And 20, after the SIM card is determined to exist, the algorithm dials in a corresponding mode according to the model of the embedded module, and after the dialing is completed, the algorithm operates in a corresponding mode for the routing table according to the parameter II transferred by the function call in the step 7.
Step 21, after dialing and operating the routing table in a corresponding manner, the electronic device executes the algorithm to send a network state query command to query the current network state through the electronic device (generally an "at+cereg.
Step 22, if the network registration connection is queried to fail, the electronic device continuously sends the network query command for 5 times at intervals of 1s, if the network registration connection is replied successfully, a successful networking log is recorded and an application program starts to run, and the current state is transferred to the cloud platform for monitoring through the mqtt protocol. Otherwise, if the process does not reply, the program switches the SIM card, and returns to step 19, and the process starts to be executed.
