[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0054] Furthermore, in this document, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0055] As can be seen from the background technology, in order to verify the reliability of the controller, a series of reliability tests are usually carried out to expose its design defects. Among them, the controller reset is often not visually observable, and according to previous test results, the controller reset action time is usually very short, so it is difficult to detect whether the controller has been reset through the execution of the load.

[0056] In view of this, the present application provides a method, system, electronic device and storage medium for detecting controller reset, so as to solve the problem in the prior art that it is difficult to detect whether a controller reset has occurred.

[0057] The present application embodiment provides a method for detecting controller reset, such as Figure 1 As shown, specifically including:

[0058] S101. Construct a detection circuit of the controller; wherein the detection circuit includes a first circuit, a second circuit and a detection light; when the controller outputs a non-zero voltage, the first circuit is turned on and the detection light is in an off state; when the output voltage of the controller is zero, the second circuit is turned on and the detection light is in a lit state.

[0059] It should be noted that first, a detection circuit including a first circuit, a second circuit and a detection light is constructed for the controller (ECU for short). When the controller works normally, the output voltage will be determined according to the controller's own specifications, such as 5V. At this time, the first circuit is turned on and the detection light is off, indicating that the output voltage of the controller is not zero. When the controller is reset due to some factors, the output voltage will be briefly pulled down to 0V. When the output voltage of the controller is zero, the second circuit is turned on and the detection light is on, indicating that the output voltage of the controller is zero, and the situation when the output voltage of the controller is zero can be intuitively observed.

[0060] Optionally, in another embodiment of the present application, an implementation of the detection circuit in the above step S101 is as follows: Figure 2 As shown, it may include:

[0061] Controller, first relay, second relay, anti-reverse diode, current limiting resistor, detection light, power supply, normally closed reset switch.

[0062] The first end of the controller is connected to the first end of the power supply, and the second end of the controller is connected to the end a of the first relay.

[0063] The b end of the first relay is connected to one end of the current limiting resistor, the c end of the first relay is connected between the controller and the power supply, and the d end of the first relay is connected to one end of the anti-reverse diode.

[0064] The a end of the second relay is connected to the other end of the anti-reverse diode and the e end of the second relay, the b end of the second relay is connected to one end of the detection lamp, and the c end of the second relay is connected to one end of the normally closed reset switch.

[0065] The other end of the detection lamp is connected between the b end of the first relay and the current limiting resistor.

[0066] The other end of the current limiting resistor is connected to the second end of the power supply.

[0067] The other end of the normally closed reset switch is connected between the controller and the power supply.

[0068] It should be noted that the detection circuit of the controller is composed of a controller, a first relay, a second relay, an anti-reverse diode, a current limiting resistor, a detection light, a power supply, and a normally closed reset switch. Among them, the e-end of the first relay and the second relay is a normally open contact, and the d-end is a normally closed contact. The normally open contact refers to a contact that is disconnected from the moving contact (c-end) under normal conditions (no power), and the normally closed contact refers to a contact that is closed with the moving contact under normal conditions. The detection circuit connects the output voltage of the ECU to the control end of the relay, and then connects it to the ground through a current limiting resistor to ensure that the circuit will not have problems due to excessive current. Placing the current limiting resistor after the relay is also to ensure that the relay will not fail due to the voltage division of the current limiting resistor.

[0069] Optionally, in another embodiment of the present application, based on Figure 2 In the detection circuit, when the controller outputs a non-zero voltage, the C terminal and the E terminal of the first relay are connected, and the C terminal and the D terminal of the second relay are connected, forming a first loop.

[0070] When the output voltage of the controller is zero, the C terminal and the D terminal of the first relay are connected, and the C terminal and the E terminal of the second relay are connected, forming a second loop.

[0071] It should be noted that when the ECU is working normally, the output voltage passes through the control end of the first relay, the ab end of the first relay is turned on, and an electromagnetic field is generated to turn on the ce end of the normally open contact circuit of the first relay. At this time, no current passes through the ab end of the second relay, and the c end and the d end are turned on to form the first circuit. No current passes through the detection light, so it is in a dark state.

[0072] When the ECU is reset, the output voltage will be pulled down to 0V, resulting in no voltage in the controller coil, and the first relay's normally closed contact loop cd end will be turned on. When the first relay's normally closed contact loop cd end is turned on, the second relay will begin to have an electromagnetic field and will turn on the second relay's normally open loop ce end, entering the self-locking power mode. Among them, the ab end of the second relay needs to flow with current in order to turn on the ce end. At the same time, after the ce end is turned on, the power supply voltage will be connected to the ab end, so that the ab end continues to flow with current, turning on the ce end, so that the second relay always remains energized and turns on the second relay's normally open loop ce end, so that the detection light remains on, so that it is easier to observe the situation where the controller's output voltage is zero. Avoid the controller reset time being too short, which will cause the detection light to be on for too short a time, making it difficult to observe this change.

[0073] S102: Detect the reset state of the controller based on the detection circuit.

[0074] It should be noted that, according to the above detection circuit, the state of the controller when the output voltage is zero can be displayed in real time by lighting the detection light, so as to detect the reset state of the controller and determine whether the controller has been reset.

[0075] Optionally, in another embodiment of the present application, an implementation of the above step S102 may include:

[0076] If the test light is on, determine if there is a timing problem in the test circuit.

[0077] If there is no timing issue, determine that the controller has reset.

[0078] It should be noted that the ECU output voltage of 0 may also be caused by a timing problem. Therefore, when the detection light is on, first determine whether there is a timing problem in the detection circuit to rule out the situation where the LED light is mistakenly lit due to a timing problem when the ECU is powered on. If there is no timing problem, it means that the controller has been reset.

[0079] Optionally, in another embodiment of the present application, the controller reset detection method may further include:

[0080] If there is a timing problem, the normally closed reset switch is controlled to open and then close to reset the detection circuit.

[0081] It should be noted that if there is a timing problem, the normally closed reset switch is controlled to open and then closed to reset the detection circuit. The normally closed reset switch can control whether the power supply voltage is connected to relay 2. If the second relay cannot be connected to the power supply voltage due to the reset switch being disconnected, the second relay cannot always remain powered on, and the normally open circuit ce end of the second relay will be disconnected, turning off the detection light, which can be understood as the initialization of the entire device.

[0082] In a method for controller reset detection provided in an embodiment of the present application, a detection circuit of the controller is constructed; wherein the detection circuit includes a first circuit, a second circuit and a detection light; when the controller outputs a non-zero voltage, the first circuit is turned on, and the detection light is in an off state; when the output voltage of the controller is zero, the second circuit is turned on, and the detection light is in a lit state. Based on the detection circuit, the reset state of the controller is detected. It can be seen that, using the method of the present application, once the output voltage of the controller is zero, the detection light in the detection circuit will be in a lit state, and when the controller is reset, the output voltage will be briefly pulled down from the normal voltage to 0V. Therefore, by observing the state of the detection light in the detection circuit, it is possible to detect in real time whether the controller has been reset.

[0083] Another embodiment of the present application also discloses a controller reset detection system, such as Figure 3 As shown, specifically including:

[0084] The detection circuit module 301 is used to construct the detection circuit of the controller; wherein the detection circuit includes a first circuit, a second circuit and a detection light; when the controller outputs a non-zero voltage, the first circuit is turned on and the detection light is in an off state; when the output voltage of the controller is zero, the second circuit is turned on and the detection light is in a lit state.

[0085] The detection module 302 is used to detect the reset state of the controller based on the detection circuit.

[0086] In this embodiment, the specific execution process of the detection circuit module 301 and the detection module 302 can be found in the corresponding Figure 1 The content of the method embodiment will not be repeated here.

The detection module 302 detects the reset state of the controller based on the detection circuit. It can be seen that, using the method of the present application, once the output voltage of the controller is zero, the detection light in the detection circuit will be in a lit state, and when the controller is reset, the output voltage will be briefly pulled down from the normal voltage to 0V. Therefore, by observing the state of the detection light in the detection circuit, it is possible to detect in real time whether the controller has been reset.
