Detailed Description
Embodiments of the application are described in detail below with reference to the attached drawings, but the application can be implemented in a number of different ways, which are defined and covered by the claims.
Embodiment one:
as shown in fig. 1, the application discloses a frequent reconnection method based on a wireless communication module of a power distribution terminal, which comprises the following steps:
when the power distribution terminal detects that the power distribution terminal drops a line, the power distribution terminal automatically sends N reconnection requests to the host in sequence through a built-in communication module, wherein N is an integer greater than 1; if the N reconnection requests fail, the power distribution terminal controls the communication module to sleep for K hours, and after the communication module is in sleep, the power distribution terminal controls the communication module to continuously send a reconnection request to the host, wherein K is a rational number greater than 0.
In addition, in the embodiment, the application also discloses a computer system, which comprises a memory, a processor and a computer program stored on the memory and capable of running on the processor, wherein the processor executes the computer program to realize the steps of the method.
According to the frequent reconnection method and the frequent reconnection system based on the wireless communication module of the power distribution terminal, the frequent reconnection method is added on the basis of the original function of the wireless module of the power distribution terminal, so that the power distribution terminal can frequently try to be connected with a main station after the power failure, the service efficiency of the power distribution terminal is improved, the monitoring and the control of the power distribution terminal by a provincial power distribution information main station can be more effectively realized, the communication module is reconnected after dormancy, the communication module has an initialization process, abnormal data or signals which cause the power failure or reconnection failure of the terminal are generated in the operation process of the terminal in the initialization process, and the probability of reconnection success again is improved.
Embodiment two:
the second embodiment is an extended embodiment of the embodiments, which is different from the first embodiment in that the frequent reconnection method based on the wireless communication module of the power distribution terminal is refined.
As shown in fig. 2, the frequent reconnection method based on the wireless communication module of the power distribution terminal in the application comprises the following steps:
step 1: the power distribution terminal detects whether the power distribution terminal drops the power or not, namely whether the power distribution terminal cannot be in communication connection with the power distribution information master station, and if the power distribution terminal detects that the power distribution terminal drops the power, the step 2 is executed;
step 2: the power distribution terminal automatically sends a hoisting connection request to the master station through the communication module;
step 3: the power distribution terminal judges whether the reconnection request is sent successfully or not, namely, whether the power distribution terminal receives a response sent by the master station after receiving the reconnection request in a preset time period, if the response is received, the reconnection request is judged to be successful, and the reconnection program is ended; if the response is not received, judging that the reconnection request fails, and then the reconnection failure times +1, namely, reconnection failure times = reconnection failure times +1, wherein the reconnection times of the power distribution terminal is initially assigned to 0; the power distribution terminal starts timing, after waiting for J seconds, judging whether the current reconnection times of the power distribution terminal are more than N times, and if so, returning to the step 2; if the number is greater than N, executing the step 4:
step 4: the power distribution terminal controls the communication module to enter a sleep mode and starts a sleep timing program, when the sleep timing reaches a preset K hour, the sleep timing program wakes up the communication module of the power distribution terminal and judges whether the reconnection failure times are more than M times, if so, the step 2 is returned, if so, the power distribution terminal controls the communication module to restart, and after the communication module is restarted, the communication module is controlled to continuously send a reconnection request until the reconnection is successful.
The power distribution terminal also executes the following steps when the communication module is dormant:
initializing data in the communication module to delete abnormal data, and controlling the communication module to perform self-checking at the same time, wherein when the communication module detects a fault, the communication module also reports a signal of 'abnormal communication module' to the power distribution terminal.
When the communication module of the power distribution terminal initiates reconnection to the master station each time, the communication module consumes the flow of the SIM card in the communication module, the flow of each SIM card is limited, and the consumption of the flow of the SIM card can be reduced by dormancy. The reason of the connection failure of the terminal and the main station mainly comprises two reasons, namely that on one hand, a communication module at the terminal side fails or the communication failure between the terminal and the main station is caused by abnormal data information, on the other hand, the communication module is dormant and initializes data in the communication module after the terminal is in repeated reconnection failure, abnormal data are deleted, meanwhile, the communication module performs self-checking, and if the communication module fails, a signal of 'communication module abnormality' is reported, the factor of the communication failure between the terminal and the main station caused by the communication module is effectively removed, and reconnection power is improved.
In this embodiment, the parameter J is an integer greater than 0, M is an integer greater than N, and the parameter M, the parameter N, the parameter J, and the parameter K may be configured according to the actual situation in the field, in this embodiment, n=10, j=60, m=30, and k=1.
In summary, the frequent reconnection method and the system based on the wireless communication module of the power distribution terminal increase the frequent reconnection method based on the original function of the wireless module of the power distribution terminal, so that the power distribution terminal can frequently try to connect with the main station after the power distribution terminal is disconnected, the service efficiency of the power distribution terminal is improved, and the monitoring and control of the power distribution terminal by the provincial power distribution information main station can be more effectively realized.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
