In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before explaining the embodiments of the present invention in detail, an application scenario of the embodiments of the present invention will be described. Currently, the use environments of smart devices such as smart televisions, computers, and the like are becoming more and more widespread. These smart devices may be used in places such as homes and offices where electromagnetic environments are relatively simple, and may also be used in places where electromagnetic environments are relatively complex. For example, in a factory building with strong electromagnetic interference, a computer for monitoring data, or a smart television arranged in the factory building for production needs. When the intelligent equipment is in a place with a complex electromagnetic environment, due to the influence of an electromagnetic field, the intelligent equipment may have the situations of blue screen, dead halt or abnormal work of part of modules, and the like.

In addition, various software programs are usually run in some modules of the smart device, and when the running software programs are jammed and cause the modules of the smart device to work abnormally, the modules of the smart device, which are abnormal, need to be reset. The method for resetting the intelligent equipment provided by the embodiment of the invention can be used for resetting the intelligent equipment with abnormal work under the condition so as to ensure that the intelligent equipment can recover to work normally in time.

After introducing the application scenario of the embodiment of the present invention, the following explains the implementation environment related to the embodiment of the present invention in detail.

Fig. 1A is an implementation environment diagram of a method for resetting an intelligent device according to an embodiment of the present invention. As shown in fig. 1, the implementation environment includes a reset device 101, monitored

modules

102 and 103, a standby module 104, a signal control circuit 105, and a motherboard 106.

The reset device 101 may be located inside the smart device, and the reset device 101 includes a plurality of input pins and a plurality of output pins, and the plurality of output pins further includes a first power-on pin and a second power-on pin, and the reset device 101 is connected to the monitored

modules

102 and 103, the standby module 104, the signal control circuit 105, and the motherboard 106 in the smart device through the plurality of input pins and the plurality of output pins. The monitored

modules

102 and 103 and the standby module 104 respectively correspond to an input pin and an output pin in the reset device 101. In addition, the reset device 101 includes a crystal oscillation circuit for providing an independent clock to the reset device 101. Alternatively, the reset device 101 may be a separate module circuit with a crystal oscillator, for example, the reset device 101 may be a power management chip with a wide power supply and less susceptible to interference.

The monitored module 102 may be a MCU (micro controller Unit), a display screen, or the like, and when the reset device 101 is used to monitor the monitored module 102, the monitored module 102 may send a pulse signal to the reset device 101 at preset time intervals.

Monitored module 103 can be other modules connected through a special symbolic I/O (Input/Output) port. When the reset device 101 is used to monitor the monitored module 103, the reset device 101 needs to detect the level state of the input pin connected to the monitored module at preset time intervals, so as to determine whether the monitored module 103 is in a normal operating state.

The standby module 104 may be used as a monitored module, and is monitored by the reset device 101, or may be used to detect whether the intelligent device has recovered to a normal operating state after the reset device 101 powers on the signal control circuit 105. When the standby module 104 is used as a monitored module, the reset device 101 needs to detect the level state of the input pin connected to the standby module 104 at preset time intervals, so as to determine whether the intelligent device is in a normal operating state.

It should be noted that the signal control circuit 105 is connected to the reset device 101 through the first power-on pin, and when the reset device 101 cannot restore the normal operation of the monitored module 102 by sending a reset signal, the signal control circuit 105 may be powered on again through the first power-on pin to implement hardware reset. In addition, the main board 106 is connected to the reset device 101 through the second power-on pin, and after the reset device 101 powers on the signal control circuit 105 again, the intelligent device still cannot be enabled to resume normal operation, and at this time, the reset device 101 may power on the main board again through the second power-on pin, so as to implement automatic restart of the whole machine.

After the description of the implementation environment related to the embodiment of the present invention, a detailed description will be given below of a specific implementation of the method for resetting the smart device according to the embodiment of the present invention with reference to the drawings.

Fig. 2 is a method for resetting an intelligent device according to an embodiment of the present invention, where the method is used in a resetting apparatus, the intelligent device includes a plurality of monitored modules, the resetting apparatus includes a plurality of input pins and a plurality of output pins, and the resetting apparatus includes a crystal oscillation circuit, and the crystal oscillation circuit is used to provide an independent clock for the resetting apparatus. As shown in fig. 2, the method comprises the steps of:

step 201: and monitoring an input pin connected with the target monitored module at preset time intervals.

The resetting device can monitor a plurality of modules in the intelligent equipment at the same time. The embodiment of the present invention will be explained by taking one monitored module of a plurality of monitored modules as an example, and for convenience of description, this monitored module is referred to as a target monitored module. The target monitored module corresponds to an input pin and an output pin in the reset device. The reset device monitors the target monitored module by monitoring the input pin connected with the target monitored module. In addition, the plurality of monitored modules may include a standby module.

Step 202: and when the monitoring result does not meet the preset condition, resetting the target monitored module through an output pin connected with the target monitored module.

When the input pin connected with the target monitored module is monitored and the obtained monitoring result does not meet the preset condition, the reset device can reset the target monitored module through the output pin connected with the target monitored module.

In the embodiment of the present invention, the reset device may monitor the input pin connected to the target monitored module at preset time intervals, and reset the target monitored module through the output pin connected to the target monitored module when the monitoring result does not satisfy the preset condition. Because this resetting means includes crystal oscillator circuit, consequently, can provide independent clock for this resetting means by this crystal oscillator circuit, like this, even outside crystal oscillator stops the vibration, this resetting means also can not stop work, promptly, this resetting means still can be reset the target monitored module that takes place the anomaly, need not the user and carries out the interchange switch machine manually and can guarantee timely normal work that resumes of smart machine, has improved user experience.

Based on the foregoing description of the implementation environment related to the embodiments of the present invention, the monitored modules can be classified into two types. Wherein, software program runs in one type of monitored module, and no software program runs in the other type of monitored module. For different types of monitored modules, the monitoring mode and the resetting mode of the resetting device are different, and next, the embodiment of the present invention will respectively describe specific implementation modes of the resetting device for resetting two different types of monitored modules with reference to fig. 3 and 4.

Fig. 3 is a flowchart of a method for resetting a smart device, according to an embodiment of the present invention, the method is used in a resetting apparatus, the smart device includes a plurality of monitored modules, the resetting apparatus includes a plurality of input pins and a plurality of output pins, and the resetting apparatus includes a crystal oscillation circuit, the crystal oscillation circuit is used for providing an independent clock for the resetting apparatus. As shown in fig. 3, the method comprises the steps of:

step 301: and monitoring whether a pulse signal is received on an input pin connected with the target monitored module at preset time intervals.

The intelligent device comprises a plurality of modules, wherein some modules can run software programs, and when the modules are monitored by the resetting device, the modules can actively send pulse signals to the resetting device according to preset time intervals. For such modules, the reset device may monitor multiple modules simultaneously. The clocks of the monitored modules can be the same clock provided by an external crystal oscillator or the clock provided by a self crystal oscillation circuit. In the embodiment of the present invention, a specific implementation manner of resetting the monitored module by the resetting device will be described by taking one monitored module of the multiple monitored modules as an example, and for convenience of description, the monitored module currently monitored by the resetting device may be referred to as a target monitored module.

When the target monitored module is in a normal running state, the target monitored module can send a preset pulse signal to the resetting device at preset time intervals according to a clock of the target monitored module, and when the target monitored module is in abnormal conditions such as jamming and the like, the target monitored module cannot send the preset pulse signal to the resetting device at the preset time intervals according to the clock.

For the above reasons, the reset device may monitor whether the input pin connected to the target monitored module receives the pulse signal at preset time intervals according to the clock provided by the crystal oscillation circuit of the reset device, and then, the reset device may determine whether the monitoring result satisfies the preset condition, so as to determine whether to reset the target monitored module.

When the reset device monitors the pulse signal and the pulse signal is the same as the preset pulse signal, it can be determined that the monitoring result meets the preset condition, that is, the target monitored module is currently in a normal operation state. When the reset device does not monitor the pulse signal or the monitored pulse signal is different from the preset pulse signal, it can be determined that the monitoring result does not satisfy the preset condition, that is, the target monitored module is currently in an abnormal operating state.

It should be noted that the preset time interval is a preset time interval for the target monitored module to send the preset pulse signal in the normal operation state, and is also a time interval for the reset device to monitor the pulse signal. In addition, the preset pulse signal may be a high pulse or a low pulse. Moreover, the preset pulse signals may be different for different target monitored modules, and may of course be the same.

Step 302: and when the monitoring result does not meet the preset condition, sending a reset signal to the target monitored module through an output pin connected with the target monitored module so as to reset the target monitored module.

When the reset device determines that the monitoring result does not satisfy the preset condition, that is, when the reset device does not detect the preset pulse signal after the preset time interval, the reset device may determine that the target monitored module is currently in an abnormal working state, and at this time, the reset device may send the reset signal to the target monitored module through an output pin connected to the target monitored module. After the target monitored module receives the reset signal, the running program in the target monitored module can be forcibly interrupted according to the reset signal, so that the target monitored module is restored to the initial state to restart working.

Alternatively, after the reset device sends the reset signal to the target monitored module, the target monitored module may fail to be reset, in which case, when the reset device detects the input pin connected to the target monitored module for a preset time interval, the monitoring result still does not satisfy the preset condition. In order to avoid the situation that the target monitored module is in an abnormal operation state for a long time due to the fact that the target monitored module cannot be reset by sending the reset signal for multiple times, before the reset device sends the reset signal through the output pin connected with the target monitored module, the reset device can also perform hardware reset on the intelligent device through the following steps.

(1) And counting the resetting times of the target monitored module, wherein the resetting times refer to the times of continuous resetting of the target monitored module before the current time.

When the monitoring result does not satisfy the preset condition, the resetting device may count the number of times that the target monitored module is continuously reset before the current time before the resetting device sends the reset signal to the target monitored module. That is, the reset means may count the number of times the reset signal has been sent to the target monitored module by the current time.

Alternatively, when the monitoring result satisfies a preset condition, it indicates that the target monitored module has been successfully reset, in which case the resetting device may set the number of resets to 0.

(2) When the reset times of the target monitored module are smaller than or equal to a first preset value, the reset signal is continuously sent to the target monitored module through an output pin connected with the target monitored module, and the reset times of the target monitored module are updated.

After the reset means determines the number of resets, if the number of resets is less than or equal to the first preset value, the reset means may try to reset the target monitored module again by sending a reset signal. That is, the reset device may continue to send the reset signal to the target monitored module through the output pin connected to the target monitored module.

After the reset signal is transmitted, the reset means may add 1 to the reset number to complete the update of the reset number.

The first preset value is a preset value according to the specific condition of the target monitored module. When the first preset value is larger, the reset device has more chances to continue to reset with the reset signal when the reset fails. For example, when the first preset value is 2, then, after the first reset failure, the reset device will only have one chance to reset the target monitored module by the reset signal. It should be noted that, the larger the first preset value is, the better the first preset value is, and if the reset signal sent by the reset device cannot reset the target monitored module all the time, the larger the first preset value is, the longer the time for the intelligent device to resume normal operation will be.

(3) When the reset times of the target monitored module are larger than a first preset value, the signal control circuit and the display panel in the intelligent device are powered on again through a first power-on pin in the plurality of output pins, and the reset times of the target monitored module are cleared.

When the reset device determines that the reset times is greater than the first preset value, the reset device may determine that sending the reset signal does not enable the target monitored module to reset, and at this time, the reset device may re-power on the signal control circuit and the display panel in the intelligent device through a first power-on pin of the plurality of output pins to perform hardware reset on the intelligent device. When the reset device powers on the signal control circuit and the display panel in the intelligent device again, the reset times of the target monitored module can be cleared.

In this case, the resetting device can determine whether the target monitored module recovers normal operation or not by the means in (4) and (5), and re-powers the whole intelligent device when the target monitored module does not recover normal operation.

(4) And detecting the level state of an input pin connected with the standby module within a preset time length, and monitoring whether a pulse signal is received on the input pin connected with the target monitored module.

After the reset device powers on the signal control circuit and the display panel in the intelligent device again through the first power-on pin, the reset device may detect whether the signal control circuit and the display panel in the intelligent device have completely recovered power supply within a preset time period.

Generally, when the smart device is in a standby state, a level state on an input pin connected to the standby module is a low level, and when the smart device is in a normal operation state, the level state is a high level. Therefore, the reset device can judge whether the intelligent equipment is powered back or not by detecting the level state of the input pin connected with the standby module. In addition, the reset device can also continuously monitor whether the input pin connected with the target monitored module receives the pulse signal, so as to judge whether the target monitored module recovers normal work.

(5) When the level state of the input pin connected with the standby module is the standby level state, or a pulse signal is not received, the pulse signal is received, and the received pulse signal is different from a preset pulse signal, the whole intelligent equipment is electrified again through a second electrifying pin in the plurality of output pins, wherein the standby level state refers to the level state of the input pin connected with the standby module when the intelligent equipment is in standby.

When the reset device detects that the level state of the input pin connected with the standby module is the standby level state within the preset time length, it indicates that the signal control circuit and the display panel of the intelligent device do not recover power supply after the preset time length after being powered on again, and at the moment, the reset device can directly power on the whole intelligent device again through the second power-on pin.

If the reset device detects that the level state of the input pin connected with the standby module is a non-standby level state within the preset time length, the state indicates that the power supply of the signal control circuit and the display panel of the intelligent device is restored after the preset time length after the signal control circuit and the display panel are powered on again. At this time, if the reset device does not receive the pulse signal or the received pulse signal is not the preset pulse signal, the reset device may determine that the signal control circuit and the display panel of the intelligent device are powered on again and the monitored module cannot be reset, and at this time, the reset device may power on the whole intelligent device again through the second power-on pin.

It should be noted that, in the embodiment of the present invention, the resetting device may reset the monitored module only in the manner of step 301 and step 302, or may reset the monitored module through

steps

301 and 302 in combination with the operations (1) - (3), and of course, the resetting device may also reset the monitored module through

steps

301 and 302 in combination with the operations (1) - (5).

The following is code provided by an embodiment of the present invention to reset the smart device through

301 and 302 in conjunction with operations (1) - (3). Assuming that the chip a is a target monitored module and is an IC (Integrated Circuit) with a program running, when the chip a is in a normal operating state, 1 high pulse is sent to the reset device through the input pin 1 connected thereto every 5s, when the chip a is in an abnormal operating state, the high pulse cannot be sent to the reset device through the input pin 1, when the reset device does not receive the high pulse for the first time, the reset device may interrupt the program running in the chip a by sending a reset signal, and when the reset device does not detect the high pulse twice continuously, the signal control Circuit may be powered up again to implement hardware reset. The specific codes are as follows:

in the embodiment of the invention, the reset device can determine whether to send the reset signal to the target monitored module by monitoring whether the preset pulse signal is received on the input pin connected with the target monitored module, and the reset device has an independent clock, so that the reset device does not stop working even if the external crystal oscillator stops vibrating, and can still reset the target monitored module which sends the abnormal signal. In addition, when the reset signal can not reset the target monitored module, the reset device can also power on the intelligent device again through the first power-on pin and the second power-on pin so as to reset the intelligent device through hardware. In addition, as can be known from the description in the foregoing implementation environment, the reset device may be located inside the smart device as a module circuit, and therefore, when the smart device is powered on, the reset device may be powered on to operate.

The above embodiments describe a method for resetting a monitored module by a resetting device when the monitored module is a module which runs a program and can actively send a pulse signal. Next, a specific implementation manner of resetting the monitored module by the resetting device when the monitored module runs without a program and needs the resetting device to actively monitor a level state will be described.

Fig. 4 is a flowchart of a method for resetting a smart device, according to an embodiment of the present invention, where the method is used in a resetting apparatus, the smart device includes a plurality of monitored modules, the resetting apparatus includes a plurality of input pins and a plurality of output pins, and the resetting apparatus includes a crystal oscillation circuit, and the crystal oscillation circuit is used to provide an independent clock for the resetting apparatus. As shown in fig. 4, the method comprises the steps of:

step 401: and monitoring the level state of an input pin connected with the target monitored module at preset time intervals.

The intelligent device usually comprises a plurality of modules which run without programs, and the resetting device can monitor a plurality of modules. When the target monitored module is a module without program operation, the reset device can detect the level state on the input pin connected with the target monitored module at preset time intervals according to the clock provided by the crystal oscillator of the reset device, and then the reset device can judge whether the monitoring result meets the preset condition so as to determine whether to reset the target monitored module.

When the reset device detects that the level state of the input pin connected with the target monitored module is the same as the stored normal level state, it can be determined that the monitoring result meets the preset condition, that is, the target monitored module is currently in a normal working state. When the reset device detects that the level state of the input pin connected with the target monitored module is different from the stored level state, it can be determined that the monitoring result does not satisfy the preset condition, that is, the target monitored module is currently in an abnormal working state. The normal level state refers to a level state on an input pin connected with the target monitored module when the target monitored module operates normally.

Optionally, in order to avoid a situation that the level state of the input pin connected to the target monitored module is not abnormal when the target monitored module is in an abnormal operation state, the reset device may monitor whether a state detection instruction sent by the target monitored module is received while monitoring the level state, where the state detection instruction is used to indicate that the target monitored module is in a normal operation state; specifically, the reset device monitors whether a pulse signal is received on an input pin connected with the target monitored module, and if the pulse signal is received, the target monitored module is considered to be in a normal operation state, otherwise, the target monitored module is in an abnormal operation state.

In this case, when the reset device detects that the level state of the input pin connected to the target monitored module is the same as the stored normal level state and receives the state detection instruction sent by the target monitored module, the monitoring result may satisfy the preset condition, that is, the target monitored module is currently in the normal working state. If the reset device detects that the level state of the input pin connected with the target monitored module is different from the stored normal level state or does not receive the state detection instruction sent by the target monitored module, at this time, the reset device can determine that the monitoring result does not meet the preset condition, that is, the target monitored module is currently in an abnormal working state.

Step 402: and when the monitoring result does not meet the preset condition, sending a re-electrifying instruction to the target monitored module through an output pin connected with the target monitored module so as to reset the target monitored module.

When the reset device determines that the monitoring result does not meet the preset condition, because no program runs on the target monitored module, the reset device can directly send a power-on command to the monitored module through an output pin connected with the target monitored module, so as to perform hardware reset on the monitored module.

Optionally, in practical applications, the monitored target module may only temporarily become abnormal, and the monitoring result monitored by the resetting device may not meet the preset condition, in this case, the monitored target module may automatically resume normal operation without being powered on again, and at this time, if the resetting device directly powers on the monitored target module again, the time for the monitored target module to resume normal operation is prolonged. In order to avoid the foregoing situation, in the embodiment of the present invention, after the resetting device determines that the monitoring result does not satisfy the preset condition, the resetting device may count the number of times that the monitoring result does not satisfy the preset condition until the current time, and when the number of times is greater than a second preset value, the resetting device sends a power-on resuming instruction to the monitored module through an output pin connected to the target monitored module, so as to reset the target monitored module.

The following is implementation code of a method for resetting a target monitored module through

steps

401 and 402 according to an embodiment of the present invention. When the chip B is in the normal operating state, it is assumed that the level state on the input pin 2 connected to the chip B is a high level, which is represented by x ═ 1, and when the chip B is in the abnormal operating state, it is assumed that the level state on the input pin 2 connected to the chip B is a low level, which is represented by x ═ 0. When the reset device detects that the level state on the input pin 2 connected with the chip B is low level three times continuously, the chip B is powered on again, and the specific codes are as follows:

in the embodiment of the present invention, the reset device may determine whether to power up the target monitored module again by monitoring a level state on an input pin connected to the target monitored module. Because the reset device has an independent clock, even if the external crystal oscillator stops vibrating, the reset device does not stop working, and the monitored module of the target sending the abnormity can still be reset. Moreover, by the reset method provided by the embodiment, for the target monitored module without program operation, the reset device can automatically reset the target monitored module through hardware reset, so that the problem that the module without program operation in the related art cannot be automatically reset because the module without program operation does not have a watchdog is solved. Meanwhile, the reset device can directly carry out automatic hardware reset on the target monitored module, so that a user does not need to manually carry out alternating current on-off, user operation is simplified, and user experience is provided.

It should be noted that, when the resetting device provided in the embodiment of the present invention is used to reset an intelligent device, the resetting device may monitor the two monitored modules simultaneously, that is, in practical applications, the resetting device may reset different monitored modules of different types through the two methods shown in fig. 3 and fig. 4.
