Please refer to fig. 1, which is a schematic diagram of a system start-up detection apparatus of an embedded device according to an embodiment of the present application. The application provides a system start detection device 1 of embedded equipment, which is used for detecting whether main control system software 103 loaded in a main control device 10 is successfully started or not, and controlling the main control device 10 to reset and restart the main control system software 103 through a reset signal when the main control device is not successfully started, so that the equipment can only be restarted due to the fact that the equipment is kept to be unable to be started when the embedded equipment is prevented from being started accidentally, and the user experience is improved. The specific features of each component in the system start-up detection apparatus 1 of the embedded device will be specifically described below.
As shown in fig. 1, a system start-up detection device 1 of an embedded device includes a main control device 10 and a monitoring circuit 20. The master device 10 includes a first output pin 101 and a reset pin 102. The monitoring circuit 20 includes a timer 203, an input pin 201 electrically connected to the first output pin 101, and a second output pin 202 electrically connected to the reset pin 102. The timer 203 is configured to start counting when the master 10 is powered on to obtain a counted time.
In the present embodiment, the master device 10 and the monitor circuit 20 are supplied with power from a common power source 30. When the embedded device is powered on, the common power supply 30 will supply power to the master control apparatus 10 and the monitoring circuit 20. The master control device 10 starts the master control system software 103 after power-up, and the monitoring circuit 20 monitors the master control device 10 after power-up. Preferably, the power supply device synchronously powers up the master device 10 and the monitoring circuit 20 so that the monitoring circuit 20 starts to count correctly when the master device 10 is powered up.
In this embodiment, when the timing time exceeds the preset time and the input pin 201 does not receive the start success signal outputted from the first output pin 101, the monitoring circuit 20 outputs a reset signal to the reset pin 102 through the second output pin 202 to control the reset and start of the master control device 10.
In this embodiment, when the counted time does not exceed the preset time and the input pin 201 receives the start success signal output from the first output pin 101, the second output pin 202 stops outputting the reset signal.
In this embodiment, the monitoring circuit 20 further includes a counter 204. When the master control apparatus 10 is reset and started, the counter 204 is used for accumulating the number of times the master control apparatus 10 is started. Specifically, when the accumulated number of times reaches the preset number of times and the input pin 201 does not receive the start success signal output from the first output pin 101, the second output pin 202 stops outputting the reset signal.
Please refer to fig. 2, which is a first flowchart of a system start-up detection method of an embedded device according to an embodiment of the present application. The application also provides a system start detection method of the embedded equipment. The embedded device includes a monitoring circuit 20, a master device 10, and a master system software 103 loaded on the master device 10. The monitoring circuit 20 includes a timing device 203, that is, the embedded device includes at least all components of the system start detection device 1 of the embedded device. The system start detection method of the embedded equipment is implemented by the embedded equipment and is used for detecting whether the main control system software 103 is successfully started or not, and controlling the main control device 10 to reset and restart the main control system software 103 in response to a reset signal when the main control device 10 is monitored to not successfully start the main control system software 103, so that the situation that the embedded equipment can only be restarted due to the fact that the embedded equipment is kept to be unable to be started when the embedded equipment is accidentally failed to be started is avoided, and the user experience is improved. Wherein the embedded device may be an electronic device embedded in a specific hardware system of a specific application. Preferably, the embedded device may be a ventilator, a computer device, or the like. The system start-up detection method comprises steps S101-S103.
Step S101, when the embedded equipment is started, the main control device is electrified to start the main control system software.
In step S101, after the embedded device is powered on, the master control system software 103 needs to be started up by the master control apparatus 10 to perform other functions of the embedded device. When the embedded device is powered on, the master control apparatus 10 attempts to start the master control system software 103, and there are two start results of successful start and unsuccessful start. When the start result is that the start is successful, the master control device 10 outputs a start success signal through the first output pin 101.
In the present embodiment, the master device 10 and the monitor circuit 20 are supplied with power from a common power source 30. When the embedded device is powered on, the common power supply 30 will supply power to the master control apparatus 10 and the monitoring circuit 20. The master control device 10 starts the master control system software 103 after power-up, and the monitoring circuit 20 monitors the master control device 10 after power-up. Preferably, the power supply device synchronously powers up the master device 10 and the monitoring circuit 20 so that the monitoring circuit 20 starts to count correctly when the master device 10 is powered up.
Step S102, the timing device is utilized to start timing when the main control device is powered on, so as to obtain timing time.
Step S103, when the timing time exceeds the preset time and the monitoring circuit does not receive the starting success signal output by the main control device, the monitoring circuit sends a reset signal to the main control device so as to control the main control device to reset and start to restart the main control system software.
In step S103, the start success signal is used to indicate that the master device 10 successfully starts the master system software 103. The monitoring circuit 20 may be a PIC single-chip microcomputer.
Please refer to fig. 3, which is a second flowchart of a system start-up detection method of an embedded device according to an embodiment of the present application. The system start-up detection method further comprises step S201.
In step S201, when the counted time does not exceed the preset time and the monitoring circuit receives the start success signal output by the master control device, the monitoring circuit stops sending the reset signal to the master control device.
In some possible embodiments, after the master control system software 103 is started successfully, the monitoring circuit 20 may continue to monitor the master control apparatus 10 according to the requirement. Specifically, the master control system software 103 will send out an operation signal to the monitoring circuit 20 at regular time after successful start. When the master control system software 103 runs abnormally, the monitoring circuit 20 does not monitor the running signal within a preset time, and the monitoring circuit 20 sends a reset signal to the master control device 10 so that the master control device 10 can respond to the reset signal to reset and restart the master control system software 103.
In this embodiment, the monitoring circuit 20 further includes a counter 204. When the master control apparatus 10 is reset and started, the counter 204 is used for accumulating the number of times the master control apparatus 10 is started.
Please refer to fig. 4, which is a third flowchart of a system start-up detection method of an embedded device according to an embodiment of the present application. The system start-up detection method further comprises step S301.
In step S301, when the accumulated times reach the preset times and the monitoring circuit does not receive the start success signal output by the master control device, the monitoring circuit stops sending the reset signal to the master control device.
In this embodiment, the preset time may be divided into a plurality of monitoring times according to the preset times. In order to reduce the repeated monitoring of the monitoring circuit 20, thereby avoiding the disturbance of the monitoring circuit 20 in the monitoring process caused by repeated monitoring while causing unnecessary load to the embedded equipment, the monitoring needs to be performed according to the preset times in the monitoring time so as to ensure accurate monitoring results. The monitoring time and the preset number of times can be adjusted according to one or more of the monitoring performance of the monitoring circuit 20, the user requirement, and the time required for the master control device 10 to send a start success signal after the master control system software 103 is started from power-up. For example, when the time required for the master device 10 to send out the start success signal after the master system software 103 is started from power-up is 1s, the monitoring time in this embodiment may be set to 1s, the preset number of times may be set to 3, that is, it is determined every 1s whether the monitoring circuit 20 monitors the start success signal, and the monitoring may be continued for at most 3 times, that is, the preset time is 3s.
Specifically, when the current monitoring time monitoring does not receive the starting success signal, judging whether the preset times are reached. When the preset number of times is not reached, the monitoring circuit 20 sends a reset signal to the master control device 10, so that the master control device 10 responds to the reset signal to reset and restart the master control system software 103, and when the next monitoring time begins, whether the monitoring circuit 20 receives a start success signal output by the master control device 10 is judged again.
In some possible embodiments, when the preset number of times is reached and the start success signal output by the master device 10 is not received, the monitoring circuit 20 may be further electrically connected to the embedded device through the second output pin 202 to output the fault information. The fault information is an sporadic fault existing in the embedded device, the master control apparatus 10, the master control system software 103, and the like. The sporadic faults include, but are not limited to, the starting moment of the embedded device, the main control system software 103 cannot be started due to uncontrollable external interference when the configuration signal state is started, the starting moment of the embedded device, the main control system software 103 cannot be started due to the influence of external interference signals on a communication interface (such as a serial port), the starting moment of the embedded device, the main control system software 103 cannot be started due to the fact that the system memory chip cannot be identified due to the interference of external factors, and the like, which are not described herein.
It will be appreciated that when the start success signal output from the master control apparatus 10 is received at any preset time within the preset number of times, the flow ends, that is, the monitoring circuit 20 stops sending the reset signal to the master control apparatus 10.
Please refer to fig. 5, which is a fourth flowchart of a system start-up detection method of an embedded device according to an embodiment of the present application. The system start-up detection method further comprises step S401.
In step S401, when the counted time exceeds the preset time and the monitoring circuit does not receive the start success signal output by the master control device, the common power supply stops supplying power to the master control device, and resumes supplying power to the master control device when the counted time exceeds the preset resume power supply time.
In step S401, on the basis that the master control device 10 restarts the master control system software 103 in response to the reset signal, when the start success signal is not monitored within the preset time, the power supply device may be directly controlled to power off the master control device 10, and after the preset power-on time is reached, the power on is performed on the master control device 10 again, so that the master control device 10 starts the master control system software 103 after power on, and then the monitoring circuit 20 monitors whether the start success signal is monitored.
