Before describing in detail the various embodiments of the present invention, the core inventive concepts of the present invention are summarized and described in detail by the following several embodiments.
The invention proposes to use the sending and receiving processor to realize the calling of the sending processing function and the receiving processing function by presetting the instruction flow and the configuration information, and flexibly adopt measures such as waiting, retrying, module restarting and the like when the instruction has an abnormal condition, thereby realizing the flexible and stable control of the 4g module.
The first embodiment is as follows:
fig. 1 is a schematic step diagram of a 4g module control method based on a FreeRTOS system according to the present invention. As shown in fig. 1, the embodiment discloses a specific implementation of a 4g module control method (hereinafter referred to as "method") based on a FreeRTOS system.
Specifically, the method disclosed in this embodiment mainly includes the following steps:
step S1: specific instruction sending processes and configuration information of the instructions, which correspond to the 4g function demand signals respectively, are preset, wherein the configuration information comprises sending processing functions, receiving processing functions, maximum retry times and waiting timeout time.
Specifically, before running, the specific instruction sending flow of some functions (such as obtaining time, sending data through TCP, etc.) and the configuration information of the instructions, which includes sending processing function, receiving processing function, maximum retry number, waiting timeout time, must be preset. The order of the instructions to be executed for realizing a certain function and the sending and receiving processing functions and parameters of each instruction can be flexibly edited.
Step S2: after the 4g module is controlled to be powered on, selecting which group of instruction sending processes to execute according to the transmitted 4g function demand signals;
specifically, since the 4g module is located as a peripheral module and has high power consumption, the module is powered off in an idle state, and the driver always belongs to a suspend wait signal state. When the driver receives a 4g function demand signal sent by the system, the whole process starts to operate. The driver will control the 4g module to power up and determine which set of instruction transmission flow to execute based on the received 4g function demand signal.
Step S3: transmitting configuration information of an instruction to be executed according to the selected instruction transmitting flow into a transmitting and receiving processor through a scheduler;
step S4: executing the instruction through the sending and receiving processor, if the instruction is executed successfully, sending a switching instruction signal to the scheduler, switching the configuration information of the next instruction to be executed according to the instruction sending flow by the scheduler and transmitting the configuration information to the sending and receiving processor, and if the instruction execution is abnormal, restarting the 4g module;
specifically, as shown in fig. 2, step S4 includes:
step S41: executing the sending processing function corresponding to the instruction, and sending the instruction;
step S42: waiting for data to return and handing out threads;
specifically, the 4g module is restarted by opening a receiver and a timer, executing a FreeRTOS signal queue waiting function to wait for data to return, and if the waiting time exceeds the waiting timeout time corresponding to the instruction and the retry number exceeds the maximum retry number corresponding to the instruction.
Step S43: and if the returned data is received, executing the receiving processing function corresponding to the instruction.
Specifically, when the returned data is incomplete, the FreeRTOS signal queue waiting function is continuously executed, and waiting is continuously performed;
when the returned data is not ideal data or needs to be acquired again due to signal problems, the sending processing function is executed again, and the 4g module is restarted after the retry number reaches the maximum retry number;
and when the returned data is ideal data, sending the switching instruction signal to a scheduler.
Therefore, when the instruction has an abnormal condition, measures such as waiting, retrying, module restarting and the like can be flexibly adopted to process the abnormal condition.
Step S5: and after the last instruction is executed, controlling the 4g module to be powered off, handing out the thread, and re-entering a signal waiting state.
Specifically, the 4g module is powered on and started up only when the system is needed, and power supply is cut off after a task is completed, so that the 4g module enters a completely power-free state. This would greatly extend its endurance for battery powered devices.
Referring to fig. 3 to 4, the following describes the application process of the method specifically as follows:
the main flow of the present technology is shown in fig. 3, and first, the flow is a task for controlling a 4g module in the whole FreeRTOS system, so that after the MCU is initialized, the task needs to be created and enters an infinite loop. The beginning of the loop is blocked by a FreeRTOS queue of signals, and can only continue to execute down after receiving a signal addressed to this queue.
Before running, the specific instruction sending flow of some functions and the configuration of the instructions must be preset, and the configuration includes sending processing function, receiving processing function, maximum retry number and waiting timeout time.
Because the 4g module is positioned as a peripheral module and has larger power consumption, the module is in a power-off shutdown state under the condition of idle, and the drive always belongs to a suspension waiting signal state. When the driver receives a 4g function demand signal sent by the system, the whole process starts to operate.
The driver first powers up the 4g module and determines which set of command transmission flow to execute based on the received signal. Then the program enters a loop, the scheduler switches the configuration information of the instruction to be executed according to the flow, and the information is transmitted to the sending and receiving processor, and the processor mainly works to execute a sending processing function, wait for data to return, execute a receiving processing function, process a waiting timeout and the like. The number of the processor outlets is two, one is that the instruction is sent and returned smoothly, the next instruction is directly executed, and the second is that an abnormal condition occurs, and the restarting module restarts the flow.
The process flow of the transceiver processor is shown in fig. 4, and is used for executing the carrier and handling the abnormal situation as the transmitting and receiving functions of a single instruction.
When the task scheduler of the main flow switches the parameters of the instruction and runs to the sender-receiver, the flow starts to run.
1) And executing a sending processing function corresponding to the instruction, sending the instruction, opening timers of the receiver and the RTOS to wait for returning data, placing a FreeRTOS signal queue waiting function, and blocking the task (handing out the thread).
2) Waiting for data to return has two consequences, waiting for a timeout and receiving a data return.
When waiting for time out (the timer reaches the target value first), it will be judged first whether the instruction retry number exceeds the maximum retry number set in the parameter, if it exceeds, it will run directly to the main flow to restart the module operation, if it does not exceed, the sending processing function will be executed again.
When a data return is received (data is received first), the data is passed to a return processing function, and there are three cases:
firstly, when the returned data is not complete, the FreeRTOS signal queue waiting function is continuously executed, namely the FreeRTOS signal queue waiting function is continuously executed;
when the returned data is not ideal data or the signal is not good and needs to be re-acquired, the instruction is retried, and the module is restarted if the retry frequency reaches the maximum limit;
and thirdly, when the returned data is ideal data, the operation scheduler is informed to switch the instruction and the parameters thereof, and the next operation is carried out.
Through the above two steps, the whole processing flow of one instruction is finished.
And finally, when the operation is operated to the last step and the function is fully completed, controlling the 4g module to be powered off, handing out the thread and reentering a signal waiting state.
The framework is based on a task blocking mechanism and a thread priority switching mechanism of the FreeRTOS, and can realize that a 4G task acquires a main thread at any time and hands over the main thread to execute other tasks when waiting. The control of the 4g module can be realized only by small system resources.
Example two:
in combination with the method for controlling a 4g module based on a FreeRTOS system disclosed in the first embodiment, this embodiment discloses a specific implementation example of a 4g module control device (hereinafter referred to as "device") based on a FreeRTOS system.
