The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.
In the embodiments of the present application, description will be made in terms of a fault diagnosis apparatus, with which the fault diagnosis apparatus can be integrated in a computer device such as a terminal device in particular. Referring to fig. 2, fig. 2 is a schematic flow chart of steps of a fault diagnosis method according to an embodiment of the present application, and when a processor on a terminal device executes a program corresponding to the fault diagnosis method, the specific flow of the fault diagnosis method is as follows:
101. and responding to a diagnosis request broadcast by the terminal to be diagnosed, and establishing an information channel which is not connected with the terminal to be diagnosed in a network manner.
The terminal to be diagnosed is equipment to be subjected to fault diagnosis, and can be any terminal equipment of the internet of things. The terminal equipment can have a networking function, for example, the terminal equipment can be connected with a corresponding background server through a local area network; the terminal device may also have a non-network connection function, where the non-network connection may be a communication connection of a non-local area network, for example, the terminal device has a bluetooth module, and performs a non-network connection with other terminal devices by using a bluetooth connection manner, so as to implement communication. The terminal to be diagnosed may be a home appliance, a vehicle-mounted device, or the like, which is not limited herein.
In order to perform fault diagnosis on the terminal equipment to be diagnosed, a communication connection between the background server and the equipment to be diagnosed can be established by using the local area network, so that remote fault diagnosis is performed on the terminal equipment to be diagnosed through the background server. In addition, the communication connection with the terminal to be diagnosed can be established under the non-local area network state, so that the fault diagnosis of the terminal to be diagnosed under the non-remote condition can be realized.
In the embodiment of the application, in order to ensure that the terminal to be diagnosed can perform fault diagnosis, the local terminal (such as equipment for performing fault diagnosis on the terminal to be diagnosed) can actively detect the network state of the local area network so as to determine whether to perform fault diagnosis on the terminal to be diagnosed under the non-local area network according to the network state.

Specifically, in order to perform fault diagnosis on a terminal to be diagnosed when network signals are poor, the embodiment of the application can actively detect the signal strength in the current network state through the local terminal, and compare the detected signal strength value with a preset signal strength threshold value to determine whether to actively perform non-network connection with the terminal to be diagnosed. When the detected signal intensity value is smaller than the preset signal intensity threshold value, the non-network connection can be actively performed with the to-be-diagnosed, and the connection establishment process between the initiative and the to-be-diagnosed comprises the following steps: and acquiring the broadcasting information of the terminal to be diagnosed, identifying whether the broadcasting information contains a diagnosis request or not when the broadcasting information of the terminal to be diagnosed is acquired, and responding to the diagnosis request broadcasted by the terminal to be diagnosed to establish an information channel which is not connected with the terminal to be diagnosed if the broadcasting information contains the diagnosis request. Therefore, the network state is actively detected, so that the non-network connection is actively carried out with the terminal to be diagnosed when the network state is poor, fault diagnosis is convenient, and the reliability is realized.

In some embodiments, the process of establishing the information channel of the non-network connection with the terminal to be diagnosed may be: identifying a broadcast identifier corresponding to the diagnosis request; and based on the broadcast identification, establishing an information channel of non-network connection with the terminal to be diagnosed.

After the broadcast identification corresponding to the diagnosis request is identified, the embodiment of the application can establish a non-network connection information channel between the broadcast identification and the terminal to be diagnosed corresponding to the broadcast identification so as to carry out fault diagnosis on the terminal to be diagnosed corresponding to the broadcast identification.

102. And sending a self-checking instruction to the terminal to be diagnosed through the information channel.
The self-checking instruction may be an instruction for controlling other devices to execute corresponding time, for example, the self-checking instruction is used for instructing the terminal to be diagnosed to execute the target fault diagnosis logic. The self-checking instruction may be generated by the local terminal when the information channel for fault diagnosis is established, or may be generated in advance.
The target fault diagnosis logic may be a logic stored in advance in the terminal to be diagnosed, specifically may be an operation logic of the terminal to be diagnosed running a corresponding function, and an operation result corresponding to the operation logic may be used for performing fault analysis and diagnosis on the local terminal, that is, determining a fault diagnosis result according to the operation result.
In order to perform fault diagnosis on a terminal to be diagnosed, after an information channel of non-network connection between a local terminal and the terminal to be diagnosed is established, the embodiment of the application can send a generated self-checking instruction to the terminal to be diagnosed through the information channel; and the terminal to be diagnosed executes the target fault diagnosis logic corresponding to the self-checking instruction to obtain an operation result corresponding to the target fault diagnosis logic, and returns the operation result to the local terminal.
By the method, the self-checking instruction can be sent to the terminal to be diagnosed so as to acquire the operation result of the terminal to be diagnosed after the related logic is operated, and the operation result can contain fault information about the terminal to be diagnosed so as to facilitate the subsequent determination of the fault result.
103. And receiving fault diagnosis information sent by the terminal to be diagnosed through the information channel.
The fault diagnosis information can be understood as an operation result generated by the terminal to be diagnosed after the terminal to be diagnosed responds to the self-checking instruction, and the operation result is specifically data corresponding to the target fault diagnosis logic.

In some embodiments, the step of generating a fault diagnosis result according to the fault diagnosis information may include:
(1) The information type of the fault diagnosis information is identified.
(2) And generating a fault diagnosis result according to the information type of the fault diagnosis information.
The information type may be understood as a specific data type or a data category of an operation result of the terminal to be diagnosed, for example, the information type may include a code, a character string, a signal code, and the like.
Specifically, in order to determine the fault condition of the terminal to be diagnosed, a corresponding fault diagnosis result may be generated according to the information type of the fault diagnosis information, so as to determine the fault condition of the terminal to be diagnosed according to the fault diagnosis result.
In some embodiments, the step of generating the fault diagnosis result according to the information type of the fault diagnosis information may include:
And (2. A.1) if the information type of the fault diagnosis information is identified as the program control code, detecting the error rate corresponding to the program control code.
And (2.a.2) generating a fault diagnosis result according to the error rate.
The program control code can be a control code of the terminal to be diagnosed when the corresponding program function is operated, belongs to an electric control signal code, and can determine whether the terminal to be diagnosed is abnormal when the corresponding program function is operated or not through the program control code, if yes, whether the terminal to be diagnosed is responded or not, and if yes, whether the control code is abnormal or not is mainly determined. For example, if the terminal is to execute the "restart" function, a program control code of the "restart" function is generated, when the program control code is abnormal, the related component cannot be controlled to run the "restart" function, so that the function does not respond, and the fault condition of the terminal to be diagnosed about the function can be identified through the program control code.
In the embodiment of the application, when the information type of the fault diagnosis information is identified as the program control code, whether the terminal to be diagnosed has the operation fault on the program function or not can be determined through the error rate of the program control code. Further, the generating the fault diagnosis result according to the error rate may specifically be: comparing the identified error rate with a preset error rate threshold, if the error rate is identified to be greater than or equal to the preset error rate threshold, determining that the terminal to be diagnosed has a program control fault, and if the error rate is identified to be less than the preset error rate threshold, determining that the terminal to be diagnosed does not have the program control fault.
Specifically, the error rate detection process may be: converting the program control code into a waveform signal; acquiring the number of low-level signals corresponding to the waveform signals; decoding the waveform signals to obtain the number of effective decoding signals corresponding to the waveform signals; and determining the bit error rate corresponding to the program control code according to the number of the low-level signals and the number of the effective decoding signals.
Specifically, the process of acquiring the number of valid decoded signals may be: identifying a start low-level signal in the waveform signal, wherein the start low-level signal is a start signal of a low-level control signal section; determining a corresponding low-level control signal segment in the waveform signal according to each initial low-level signal; acquiring the trigger time of each low-level signal in the low-level control signal section, and acquiring the target interval time between two adjacent trigger times; converting each target interval time into a corresponding signal value to obtain target decoding information corresponding to each low-level control signal segment; extracting an information code and a check code in each target decoding information; checking the information code according to the check code; and when the information code and the check code in the target decoding information are symmetrical, determining the target decoding information with the symmetrical information code and the symmetrical check code as effective decoding information, and obtaining the quantity of the effective decoding information.
In some embodiments, the step of generating the fault diagnosis result according to the information type of the fault diagnosis information may include:

And (2.b.2) if the packet loss rate is detected to be larger than the preset packet loss rate threshold value, determining that the terminal to be diagnosed is in a data transmission abnormal state, and determining the data transmission abnormal state as a fault diagnosis result.
The packet loss rate refers to the ratio of the number of lost data packets in the self-checking process of the terminal to be diagnosed to the transmitted data set. The packet loss rate can reflect the network data packet transmission rate of the terminal to be diagnosed so as to determine whether a data transmission fault exists or not, and the data packet transmission is reflected before.
From the above, the embodiment of the application can respond to the diagnosis request broadcast by the terminal to be diagnosed and establish the information channel of non-network connection with the terminal to be diagnosed; sending a self-checking instruction to the terminal to be diagnosed through the information channel, wherein the self-checking instruction is used for indicating the terminal to be diagnosed to execute target fault diagnosis logic; receiving fault diagnosis information sent by a terminal to be diagnosed through an information channel, wherein the fault diagnosis information is data corresponding to a target fault diagnosis logic; and generating a fault diagnosis result according to the fault diagnosis information. Therefore, in order to respond to the diagnosis request broadcast by the terminal to be diagnosed, the scheme can establish an information channel which is not connected with the terminal to be diagnosed so as to meet the communication requirement of the terminal to be diagnosed in diagnosis, and further, the fault diagnosis information of the terminal to be diagnosed when the target fault diagnosis logic is executed is obtained through the information channel which is not connected with the network so as to determine the fault diagnosis result according to the fault diagnosis information; therefore, the dependence on the network state is eliminated, the fault diagnosis information of the terminal to be diagnosed is received in real time, the fault condition of the terminal to be diagnosed is obtained, the fault diagnosis of the household appliance can be realized in the network-free state, and the fault diagnosis efficiency of the household appliance is improved.
In the embodiments of the present application, description will be made in terms of a fault diagnosis apparatus, with which the fault diagnosis apparatus can be integrated in a computer device such as a terminal. Referring to fig. 3 and fig. 4, fig. 3 is a flowchart illustrating further steps of the fault diagnosis method according to the embodiment of the present application, and fig. 4 is a timing flowchart of the fault diagnosis method according to the embodiment of the present application, which is described in conjunction with fig. 3 and fig. 4 for ease of understanding.
The embodiment of the application comprises a diagnosed terminal and a local terminal, wherein the local terminal is used for performing fault diagnosis on the terminal to be diagnosed. It should be noted that, the local terminal and the diagnosed terminal both have non-network connection functions, and the local terminal and the diagnosed terminal can be connected through the non-network to realize data transmission between the two terminals. When the processor on the diagnosed terminal and the local terminal execute the program corresponding to the fault diagnosis method, the specific flow of the fault diagnosis method is as follows:
201. The local terminal searches the broadcasting information of the terminal to be diagnosed.
For communication connection with the terminal to be diagnosed, the broadcasting information can be searched for to determine the connectable terminal to be diagnosed according to the broadcasting information.
202. When the local terminal finds that the broadcasting information of the terminal to be diagnosed contains a diagnosis request, the local terminal responds to the diagnosis request broadcasted by the terminal to be diagnosed and establishes an information channel which is not connected with the terminal to be diagnosed in a network manner.
Specifically, in order to establish an information channel of non-network connection with a terminal to be diagnosed, so as to obtain fault diagnosis information of the terminal to be diagnosed, after obtaining that broadcast information of the terminal to be diagnosed includes a diagnosis request, the embodiment of the application identifies a broadcast identifier corresponding to the diagnosis request, and can establish an information channel of non-network connection with the terminal to be diagnosed corresponding to the broadcast identifier, so as to perform fault diagnosis on the terminal to be diagnosed corresponding to the broadcast identifier.
203. The local terminal generates a self-checking instruction and sends the self-checking instruction to the terminal to be diagnosed through the information channel.
The self-checking instruction may be an instruction for controlling other devices to execute corresponding time, for example, the self-checking instruction is used for instructing the terminal to be diagnosed to execute the target fault diagnosis logic. The self-checking instruction may be generated by the local terminal when the information channel for fault diagnosis is established, or may be generated in advance.
In order to perform fault diagnosis on a terminal to be diagnosed, after an information channel of non-network connection between a local terminal and the terminal to be diagnosed is established, the embodiment of the application can send the generated self-checking instruction to the terminal to be diagnosed through the information channel.
204. The diagnosed terminal receives the self-checking instruction sent by the local terminal through the information channel, and executes the target fault diagnosis logic corresponding to the self-checking instruction to obtain the fault diagnosis information corresponding to the target fault diagnosis logic.
The fault diagnosis information can be understood as an operation result generated by the terminal to be diagnosed after the terminal to be diagnosed responds to the self-checking instruction, and the operation result is specifically data corresponding to the target fault diagnosis logic.
The target fault diagnosis logic may be a logic stored in advance in the terminal to be diagnosed, specifically may be an operation logic of the terminal to be diagnosed running a corresponding function, and an operation result corresponding to the operation logic may be used for performing fault analysis and diagnosis on the local terminal, that is, determining a fault diagnosis result according to the operation result.
205. And the local terminal receives fault diagnosis information sent by the terminal to be diagnosed through the information channel.
Specifically, fault diagnosis information sent by the terminal to be diagnosed through the information channel is detected and received in real time, so that data for determining actual fault conditions are obtained, and fault result determination is conveniently carried out according to the fault diagnosis information.
206. And the local terminal generates a fault diagnosis result according to the fault diagnosis information.
In the embodiment of the application, in order to determine the fault condition of the terminal to be diagnosed, a corresponding fault diagnosis result can be generated according to the information type of the fault diagnosis information so as to determine the fault condition of the terminal to be diagnosed according to the fault diagnosis result.
For example, when the information type of the fault diagnosis information is identified as a program control code, whether or not the terminal to be diagnosed has an operation fault on the program function can be determined by the error rate of the program control code. Further, the generating the fault diagnosis result according to the error rate may specifically be: comparing the identified error rate with a preset error rate threshold, if the error rate is identified to be greater than or equal to the preset error rate threshold, determining that the terminal to be diagnosed has a program control fault, and if the error rate is identified to be less than the preset error rate threshold, determining that the terminal to be diagnosed does not have the program control fault.
For another example, if the information type of the fault diagnosis information is identified as the packet loss rate, comparing the packet loss rate with a preset packet loss rate threshold; and when the packet loss rate is detected to be larger than a preset packet loss rate threshold value, determining that the terminal to be diagnosed is in a data transmission abnormal state, and determining the data transmission abnormal state as a fault diagnosis result.
