Embodiment 1

[0058] figure 1 It is a schematic diagram of the steps of a 4g module control method based on the FreeRTOS system provided by the present invention. Such as figure 1 As shown, this embodiment discloses a specific implementation of a FreeRTOS system-based 4g module control method (hereinafter referred to as "method").

[0059] Specifically, the method disclosed in this embodiment mainly includes the following steps:

[0060] Step S1: Preset the specific instruction sending process and instruction configuration information respectively corresponding to the 4g function requirement signal. The configuration information includes sending processing function, receiving processing function, maximum number of retries, and waiting timeout time.

[0061] Specifically, before running, it is necessary to preset the specific instruction sending process and instruction configuration information of some functions (such as obtaining time, sending data through TCP, etc.), these configuration ...

Embodiment 2

[0095] Combined with the 4g module control method based on the FreeRTOS system disclosed in the first embodiment, this embodiment discloses a specific implementation example of a 4g module control device based on the FreeRTOS system (hereinafter referred to as "device").

[0096] refer to Figure 5 As shown, the device includes:

[0097] Information preset unit 1: preset the specific instruction sending process corresponding to the 4g function requirement signal and the configuration information of the instruction, the configuration information includes sending processing function, receiving processing function, maximum number of retries , Wait for the timeout.

[0098] Signal receiving unit 2: After controlling the 4G module to be powered on, select which group of instruction sending process to execute according to the incoming 4G function requirement signal;

[0099] Configuration information sending unit 3: transmit the configuration information of the instruction to be exe...

Abstract

The invention discloses a 4g module control method and device based on a FreeRTOS system, and the method comprises the steps of controlling a 4g module to be powered on, and selecting which group of instruction sending processes is executed according to an transmitted 4g function demand signal; transmitting configuration information of an instruction to be executed to a sending and receiving processor through a scheduler according to the selected instruction sending process; executing the instruction through the sending and receiving processor, if the instruction is successfully executed, sending a switching instruction signal to the scheduler, switching configuration information of a next instruction to be executed by the scheduler according to an instruction sending process and transmitting the configuration information to the sending and receiving processor, and if instruction execution is abnormal, restarting the 4g module; after the last instruction is executed, controlling the 4g module to be powered off, releasing the thread, and the 4g module entering the signal waiting state again. Through the method, the 4g module can be controlled more flexibly and stably.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a 4G module control method and device based on FreeRTOS system. Background technique [0002] At present, the control of the 4G module has the following characteristics: [0003] 1. Since it takes a certain amount of time for the 4G module to query and connect to the network, the MCU sends some instructions to the 4G module (such as querying the network status, connecting to the tcp terminal, etc.), and the speed of receiving feedback data is relatively slow. [0004] 2. To complete a certain task (obtain time, report information to the server, etc.), the MCU needs to send instructions in order, and the sending combinations of different task instructions are different. [0005] 3. The timeout waiting time required by each command is different, and when a timeout error occurs, it is necessary to flexibly determine the next operation according to the situation. [...
