Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of illustrating the present application and are not to be construed as limiting the present application.
Several terms which are referred to in this application are first introduced and explained:
and the micro control equipment comprises: the micro control devices related to the application are all referred to as MCU (Micro Controller Unit, micro control unit), and the MCU has a very important branch, namely a singlechip. The functional modules integrated on the MCU may include: first, the timer includes a timer with a fixed time interval and a programmable timer, wherein the timing time of the timer with the fixed time interval is determined according to a fixed time interval provided by the MCU, and the timing time of the programmable timer is determined according to a program set by a user, specifically, a clock source, a frequency division number and a preset number are selected through the set program, and since the clock source of the programmable timer can be freely selected, such a timer is generally used together with an Event Counter. Second, external interrupts, which are generally based on real-time requirements, are the most desirable choice for detection of bursty signals in order to ensure that the signal is not missed. Third, watchdog timers (also known as Watchdog) typically provide a self-recovery function for MCUs that crash due to unexpected failures. The MCU has many other functions, which will not be described further herein due to space limitations.
Transceiver device: the transceiver device related to the present application refers to a wireless chip connected to an MCU, and the wireless chip has a communication function, and the communication function in the present application specifically refers to wireless communication performed by an existing wireless communication technology.
Referring to fig. 1, the prior art discloses a structure diagram of a wireless networking, which is composed of a plurality of wireless modules, and each wireless module should include an MCU and a wireless chip. Specifically, the MCU is a core module of each wireless module, directly controls other functional modules of the wireless module, including controlling the wireless chip, and the communication between the wireless modules mainly depends on the communication function of the wireless chip. In addition, the wireless networking comprises a host wireless module and a slave wireless module, and the running state of the wireless networking can be as follows: the host wireless module is connected with each slave wireless module, and the host wireless module respectively sends instructions to each slave wireless module and receives information fed back by each slave wireless module, or the slave wireless module respectively sends information to the host wireless module and respectively receives information fed back by the host wireless module.
From the communication perspective, whether the functional status of the wireless chip of each wireless module is good is one of the key factors of whether the wireless networking can normally operate. When communication abnormality occurs in the wireless networking, particularly, communication abnormality caused by abnormality of the wireless module, the cause can be traced back to the MCU and the wireless chip in general. Since the MCU can realize abnormal self-recovery through the watchdog function, it is particularly important to detect and self-recover the abnormality of the wireless chip. In the prior art, two schemes are provided to realize the anomaly detection and recovery of the wireless chip.
First, the software resets. The MCU queries the register state of the wireless chip according to the preset frequency, and performs exception handling once the state of a certain register is found to be beyond a normal value. The method is mainly aimed at that when the wireless chip can not normally execute the receiving and transmitting operation, the values of some registers can not be changed normally, and the abnormality can be detected by detecting the state of the registers. After determining that the wireless chip is abnormal, the MCU sends a reset instruction to the wireless chip to perform abnormality recovery. However, this method requires the MCU to separately develop a task line, performs detection for a plurality of register states, consumes resources, and is inefficient.
Second, the hardware is reset. The reset pin of the wireless chip is pulled down or pulled up by people, so that the wireless chip resets itself. However, when the reset pin is operated to reset the wireless chip, the original execution logic of the wireless chip is disturbed, and in such a case, the wireless chip is initialized, and thus initialization abnormality is very likely to occur.
That is, the software reset and hardware reset methods provided in the prior art either occupy the resources of the wireless module, i.e. have low efficiency, or generate an abnormal initialization, i.e. have failed initialization.
The application provides a method, a device and a storage medium for processing abnormal receiving and transmitting, which aim to solve the technical problems in the prior art.
The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described below with reference to the accompanying drawings.
Referring to fig. 2, a possible block diagram of a wireless module is provided in the embodiment of the present application, and the wireless module is applied to the wireless networking in fig. 1, so that a method for processing abnormal transceiving provided in the embodiment of the present application may be implemented based on the possible block diagram.
Referring to fig. 3, an embodiment of the present application provides a possible flowchart of a method for handling a transception exception. The method is applied to micro-control equipment, and the micro-control equipment is configured in the first wireless module and is connected with the transceiver equipment in the first wireless module. The method comprises the following steps:
s110, initializing a timer and a count value according to a preset period when the preset period arrives and an external interrupt signal is not detected;
the first wireless module and the second wireless module form a wireless networking. When the first wireless module is a master wireless module, the second wireless module is a slave wireless module; when the first wireless module is a slave wireless module, the second wireless module is a master wireless module.
In the wireless networking according to the embodiment of the present application, the number of the slave wireless modules and the number of the master wireless modules are at least one. The transceiver of the master wireless module and the transceiver of the slave wireless module communicate by adopting a wireless communication technology, and the wireless communication technology can comprise: zigbee, bluetooth, etc.
In one possible implementation, after the micro control device is started, an external interrupt signal triggered by the transceiver device after performing the receiving/transmitting operation is detected according to a preset frequency. Specifically, the first wireless module and the second wireless module confirm each other's status, particularly confirm each other's communication status, by transmitting and receiving each other's status information according to a preset period. When the transceiver performs a receiving/transmitting operation, the external interrupt of the micro-control device is triggered, so as to generate an external interrupt signal, and after the micro-control device detects the external interrupt signal, it can be determined that the connected transceiver and the transceiver of other wireless modules can perform a normal receiving/transmitting operation, that is, the communication function is normal.
In addition, the period corresponding to the preset frequency is smaller than or equal to the preset period, that is, the frequency of detecting the external interrupt signal is greater than the frequency of transmitting/receiving the state information. With such an arrangement, the micro control device can detect the external interrupt signal.
The state information may be specifically a heartbeat packet, and then the preset period may be a transmission period of the heartbeat packet, that is, a heartbeat period. The receiving and transmitting equipment of the first wireless module sends a heartbeat packet according to a preset period, and correspondingly, the receiving and transmitting equipment of the second wireless module receives the heartbeat packet and feeds back the heartbeat packet to the first wireless module. Or the receiving and transmitting equipment of the second wireless module transmits the heartbeat packet according to the preset period, and correspondingly, the receiving and transmitting equipment of the first wireless module receives the heartbeat packet and feeds back the heartbeat packet to the second wireless module.
Illustratively, in fig. 2, the micro control device, i.e., MCU, and the transceiver device, i.e., wireless chip. The connection between the MCU and the wireless chip may include: RESET connection line (i.e. connection line with RESET mark), external interrupt connection line (i.e. connection line with IO mark), and communication bus for other communication, wherein two ends of each connection line are corresponding to pins of wireless chip and MCU, which can generate interrupt signal, RESET signal, etc. For example, when the wireless chip completes the receiving/transmitting operation once, the external interrupt of the MCU is triggered through the external interrupt connecting wire, so that an external interrupt signal is generated at the pin of the MCU of the connecting wire, and the MCU invokes an external interrupt service interface after detecting the external interrupt signal; for example, the MCU may also trigger a reset signal by resetting the connection line in a program control manner, so that a reset signal is generated at a pin of the wireless chip of the connection line, and after the wireless chip detects the reset signal, the wireless chip invokes a reset interface to execute a reset operation.
S120, adding the count value according to the detected timer interrupt signal:
s130, corresponding abnormal receiving and transmitting processing operation is executed according to the relation between the count value and the count threshold.
In one possible implementation manner, initializing the timer and the count value according to the preset period in S110 specifically includes:
initializing a timing period of a timer to be a preset period, and starting the timer; the initialization count value is zero.
After the timer is started, a timer interrupt is triggered once every time a timing period is reached, specifically, a timer interrupt signal is generated, and after the micro control device detects the timer interrupt signal, a timer interrupt service interface is called, so that the adding operation of the count value is realized through the interface.
In addition, it is a common and suitable way to set the timing period of the timer to a preset period and to set the adding operation to the count value, specifically, the adding operation to 1. When the operation of adding 1 is set, the essence is that in the transmission process of the simulated heartbeat packet, after the count value reaches the specified threshold value, the side surface reflects that the heartbeat packet is not received in the specified several heartbeat cycles, and in this case, the abnormal receiving and transmitting can be judged. The technical means provides a certain buffer time for the transceiver of the wireless module. The abnormal reasons of the transceiver are numerous, and the abnormal reasons include the abnormal conditions caused by external interference, and the normal receiving/transmitting operation can be restored after the external interference is relieved or eliminated. If normal reception/transmission operation can be resumed, it is not necessary to implement abnormal resumption by a reset operation.
It should be noted that triggering a timer interrupt and triggering an external interrupt are two tasks that are executed asynchronously. Accordingly, the micro control device invokes the external interrupt service interface and the timer interrupt service interface are two asynchronous operations.
The timer interrupt service interface (also referred to as an interface function, in a software program for the MCU, there is a specially provided interface function for processing a service corresponding to the timer interrupt, and program expansion can be performed for the interface function to implement service expansion, for example, 1-adding operation for a count value, and in the software program, there is a specially provided interface function for processing a service corresponding to an external interrupt, and similarly, program expansion can be performed for the interface function to implement service expansion, for example, zero clearing operation for a count value), and the interface is expanded for implementing operation for self-adding 1 for a count value.
After the timing period of the timer is set to be a preset period, the counting threshold may be set according to a threshold setting instruction input by the user.
The application provides a method for processing abnormal receiving and transmitting, which is applied to micro-control equipment, wherein the micro-control equipment is configured in a first wireless module and is connected with receiving and transmitting equipment in the first wireless module; when a preset period arrives and an external interrupt signal is not detected, initializing a timer and a count value according to the preset period; adding the count value according to the detected timer interrupt signal; and executing corresponding abnormal receiving and transmitting processing operation according to the relation between the count value and the count threshold.
Compared with the anomaly recovery strategy provided in the prior art, the method can effectively utilize the external interrupt signal, starts the step of judging the receiving and transmitting anomalies when the receiving and transmitting anomalies are found, and does not directly perform the reset operation, and the corresponding operation of processing the receiving and transmitting anomalies is performed only after the count value and the count threshold meet a certain relation. In general, the method for processing the abnormal transceiving operation provided by the embodiment of the application effectively improves the processing efficiency of the abnormal transceiving operation.
As in the above embodiments, since the reason for the abnormality of the transceiver is numerous, in which the abnormality caused by the external interference is included, the normal receiving/transmitting operation can be resumed after the external interference is released or vanished. Also for this case, a reset operation is not required. Accordingly, there is provided in an embodiment of the present application a possible implementation manner, including:
when the external interrupt signal is detected, the count value is cleared, and the transceiving equipment is determined to be normal in transceiving.
Specifically, after detecting the external interrupt signal, the micro control device invokes an external interrupt service interface, and performs a zero clearing operation on the count value through the interface. Moreover, the micro control device detects the external interrupt signal, which indicates that the transceiver device performs the transmitting/receiving operation, that is, the normal communication function is restored. Note that, in the embodiment of the present application, the normal transceiving indicates that the receiving/transmitting function is normal, and the abnormal transceiving identifies that the receiving/transmitting function is abnormal.
Wherein after determining that the communication function of the transceiver is good, the transceiver does not need to be reset. Therefore, after the external interrupt signal is detected, the count value is cleared, so that when the count value reaches the count threshold value, the micro control device performs an exception handling operation.
In addition, after the count value is cleared, the timer may be suspended or closed to terminate the operation of this transmission/reception abnormality determination.
One possible implementation manner is provided in the embodiment of the present application, where S130 includes S130a1 (not shown in the figure) and S130a2 (not shown in the figure), specifically,
s130a1, when the count value is equal to the count threshold value, sending a notification message to the transceiver device, wherein the notification message is used for notifying the transceiver device to perform a sending operation;
and S130a2, when the external interrupt signal is detected, determining that the transceiving equipment is normal in transceiving and the transceiving equipment of the second wireless module connected with the first wireless module is abnormal in transceiving.
Specifically, the transmitting and receiving device performs a transmission operation after receiving the notification message. The transmitting operation should be that the transceiver of the first wireless module transmits the status information to the second wireless module.
If the execution is successful, the external interrupt is triggered, an external interrupt signal is generated, and when the micro control device detects the external interrupt signal, a corresponding external interrupt service interface is called, and the count value is cleared in the interface. In addition, receiving the external interrupt signal also indicates that the transceiver connected with the micro-control device is normal in transceiver, so that the transceiver of the second wireless module connected with the first wireless module cannot perform transceiver operation.
In view of this situation, the micro control device may continue to execute tasks according to the original execution logic, zero out the count value, close the timer, and suspend detection of the timer interrupt signal.
If the execution fails, the external interrupt cannot be triggered. This situation also illustrates that the key cause of the transception abnormality is an abnormality of the transception device connected to the micro control device.
In one possible implementation, S130 further includes S130b1 (not shown) and S130b2 (not shown), and in particular,
s130b1, when the count value is larger than the count threshold value, determining that the transceiving equipment is abnormal in transceiving;
and S130b2, sending a reset message to the transceiver to inform the transceiver to execute a reset operation.
Specifically, if the transceiver fails to perform the transmission operation, the external interrupt cannot be triggered, and then the zero clearing operation cannot be performed on the count value. In addition, when a new timing period arrives, a timer interrupt signal is generated, and the micro control device needs to call a timer interrupt service interface to add the count value, and after the adding operation is performed, the count value is greater than the count threshold value. Therefore, when the count value is greater than the count threshold value, it can be inferred that the external interrupt signal is not detected, and the transceiver device fails to perform the transmission operation.
Accordingly, it is necessary to transmit a reset message to the transceiver device to inform the transceiver device to perform a reset operation.
After receiving the reset message, the transceiver executes a reset operation according to a preset reset mode. After the reset operation is performed, the normal reception/transmission operation can be resumed.
The embodiment of the application also provides a wireless module, which comprises a micro-control device and a transceiver device, wherein when the transceiver device executes receiving/transmitting operation, an external interrupt signal is generated, wherein,
the micro-control device is used for initializing a timer and a count value of the micro-control device according to a preset period when a preset period arrives and an external interrupt signal is not detected;
the micro-control device is also used for adding the count value according to the detected timer interrupt signal;
the micro-control device is also used for executing corresponding abnormal receiving and transmitting processing operation according to the relation between the count value and the count threshold value.
The wireless module in the embodiment of the application comprises a host wireless module and a slave wireless module. The host wireless module mainly sends instructions to the slave wireless module, and the slave wireless module receives the instructions and executes corresponding operations. When the transceiver of the wireless module executes receiving and transmitting operations, external interruption of the micro-control equipment is triggered, so that the micro-control equipment generates external interruption signals.
In one possible implementation manner, the micro control device is specifically configured to:
when the count value is equal to the count threshold, the micro-control device sends a notification message to the transceiver device so as to notify the transceiver device to perform sending operation;
when the micro-control device detects an external interrupt signal, the receiving and transmitting device is determined to receive and transmit normally;
or,
when the count value is larger than the count threshold value, determining that the transceiving equipment is abnormal in transceiving;
the micro control device sends a reset message to the transceiver device to inform the transceiver device to execute a reset operation.
Referring to fig. 4, the embodiment of the present application further provides a possible flowchart of a transceiver anomaly recovery procedure from the perspective of the micro control device of the first wireless module. The MCU1 and the wireless chip 1 are respectively micro control equipment and receiving and transmitting equipment of the first wireless module.
S401, the MCU1 initializes a timer and a count value.
Specifically, when the MCU1 does not detect the external interrupt signal, a timer is started, and the timing time of the timer is set to be one heartbeat period.
In addition, a count value needs to be initialized, and the initial value of the count value is zero.
It should be noted that, since the timer interrupt and the external interrupt are two tasks that are executed asynchronously, they do not affect each other. Thus, after starting the timer, it is also possible for the MCU1 to detect an external interrupt signal so that an external interrupt service interface may be invoked. Thus, the present flow divides the step of S402 into S402a and S402b, which are described in two separate branches. In particular, the method comprises the steps of,
s402a branch:
s402a1, the MCU1 determines whether a timer interrupt signal is detected.
Specifically, if detected, return to wait for the next timing cycle to wait for execution of S402a1; if not, S402a2 is performed.
S402a2, the MCU1 calls a timer interrupt service interface;
in the interface, an operation of adding 1 to the count value is performed;
s402a3, after performing an operation of adding 1 to the count value, the MCU1 determines whether the count value is equal to 3. In particular, the method comprises the steps of,
if equal, S403a is performed.
If not, S403b1 is executed.
S402b branches:
s402b1, the MCU1 determines whether an external interrupt signal is detected.
If so, S402b2 is performed.
S402b2, the timer is closed, and the count value is cleared.
After detecting the external interrupt signal, it is indicated that the wireless chip 1 is transmitting and receiving normally, and the detection of abnormality can be stopped, and the present flow can be ended.
In S402a3, the count value is determined, and 2 different results are obtained according to the determination. Thus, the flow of S403 is split into 2 independent branches: s403a and S403b. In particular, the method comprises the steps of,
s403a branch:
s403a, the MCU1 notifies the wireless chip 1 to perform a transmission operation.
Wherein the transmission operation is for detecting whether or not an abnormality of the wireless chip 1 causes a transmission/reception abnormality. If the wireless chip 1 performs the transmission operation, an external interrupt signal is triggered, that is, the execution of S402b1 to S402b2 is started. If the transmission operation is not performed, the next timing cycle is reached, and the process returns to S402a2.
S403b branch:
s403b1, the MCU1 determines whether the count value is greater than 3.
If it is smaller than, return is made and execution of S402a2 is awaited. If so, S403b2 is performed.
S403b2, the MCU1 turns off the timer interrupt and clears the count value.
S403b3, the MCU1 notifies the wireless chip 1 of reset.
Specifically, the MCU1 transmits a reset signal to the wireless chip 1 to inform the wireless chip 1 to perform reset.
After the wireless chip 1 executes the software reset, the system is restarted, and the execution of the flow of the S403b branch is completed, which also represents that the execution of the flow is completed.
The embodiment of the present application further provides an apparatus for processing abnormal transceiving, as shown in fig. 5, the apparatus 50 may include: a timed interrupt module 501, an exception handling module 502, an external interrupt module 503, a detection module 504, wherein,
the timer interrupt module 501 includes a timer for initializing a timer and a count value according to a preset period when a preset period arrives and an external interrupt signal is not detected;
the timer interrupt module 501 is further configured to add a count value according to the detected timer interrupt signal;
