DETAILED DESCRIPTION

[0013] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

When a component is referred to as being "connected" to another component, it can be directly or indirectly connected to the other component.

For those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances. The terms "first", "second" are only for the convenience of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0015] Before describing the technical solutions of the present application, the background of the present application is described.

[0016] According to the background art, when a large number of circuit boards preloaded with different embedded software are received, the circuit boards cannot be classified by embedded software because their appearances are basically the same. Therefore, it is necessary to design an efficient identification method for preloading embedded software on circuit boards.

[0017] Taking the circuit board of the fan (brushless) of the sweeping robot as an example, the circuit board is preloaded with embedded software. The circuit board can have four hardware interfaces, which are VCC interface, FG interface, PWM interface (which can not be set) and GND interface. Among them, the VCC interface is used to connect to an external power supply; the FG interface can output under the control of the embedded software (for example, output a square wave representing the speed when the fan is working); the PWM interface can adjust the duty cycle under the control of the embedded software, so as to adjust the speed of the fan; the GND interface is used for grounding. It should be noted that the embedded software can output a square wave representing the information (such as version information) of the embedded software itself through the FG interface of the circuit board, and is not limited to the square wave representing the speed.

[0018] Referring to Figure 1 An embodiment of the present application provides an embedded software identification method. The embedded software is loaded on a circuit board and outputs an identification code under a predetermined condition. In one possible example, the predetermined condition refers to that when the fan is not working, the embedded software outputs the identification code through the FG interface.

[0019] The embedded software identification method of the embodiment can include the following steps: S1, obtaining the real-time input quantity of the input end of the circuit board.

[0020] In this step, the real-time input quantity can be a real-time input voltage, a real-time input current or a real-time input power. For example, the analog voltage at the input end can be monitored in real time through an ADC (analog-to-digital conversion), and the analog voltage is converted into a digital voltage for machine recognition. The following embodiments are described by taking the voltage as an example, and similar descriptions for other real-time input quantities are not repeated here.

[0021] S2, determining the first threshold value or the second threshold value based on the working condition of the circuit board.

[0022] In this step, the working condition of the circuit board can be confirmed in real time or be set in advance. For example, for the circuit board, the working condition can be an overvoltage condition, that is, working at the upper end of the specific working range of the fan, and the working condition can also be an undervoltage condition, that is, working at the lower end of the specific working range of the fan. For example, the working range of the fan is A1-A2 (voltage), where A2 is greater than A1, the overvoltage condition is greater than A2, and the undervoltage condition is less than A1.

[0023] S3, comparing the real-time input quantity with the first threshold value or the second threshold value.

[0024] S4, receiving the identification code output by the output end of the circuit board when the real-time input quantity is less than or equal to the first threshold value or when the real-time input quantity is greater than or equal to the second threshold value.

[0025] In this step, the threshold value is the first threshold value under the undervoltage condition, and the threshold value is the second threshold value under the overvoltage condition. It can be understood that the first threshold value and the second threshold value are both the limit range of the required input quantity for the normal working of the fan, so whether the real-time input quantity is less than the first threshold value or the real-time input quantity is greater than the first threshold value, the fan is in a non-working state under the control of the circuit board.

[0026] It should be noted that the traditional embedded software does not control the output of the FG interface (or outputs meaningless noise) at this time, and the interface has low utilization efficiency. Since the embedded software to be identified in the present application works outside the above-mentioned specific working range, the output end of the circuit board outputs the identification code of the software, and the embedded software identification method of the present application can determine whether the circuit board is in a normal working state through the relationship between the real-time input quantity and the threshold value; if the circuit board is in a non-normal working state, the identification code output by the output end of the circuit board is received.

[0027] It should be noted that if the circuit board is in a normal working state, the FG interface needs to normally output a square wave representing the operation of the fan at this time, and the FG interface is occupied at this time, and the output of the output end of the circuit board is not received.

[0028] S5, determining the embedded software loaded on the circuit board based on the identification code.

[0029] In this step, after receiving the identification code, the embedded software can be quickly confirmed, for example, the version information or name information of the embedded software is confirmed through the identification code, so that the circuit board can be quickly classified.

[0030] The embedded software identification method of the present application monitors the real-time input quantity of the input end of the circuit board, selects a corresponding threshold value according to the working condition, and when the real-time input quantity and the threshold value meet certain conditions, the identification code of the embedded software can be received from the output end of the circuit board. The identification code can be used to confirm the embedded software loaded on the circuit board. Compared with the traditional method of re-flashing the program of the circuit board or cross-testing the circuit board, the embedded software can be quickly identified without adding hardware and disturbing the normal function.

[0031] In one possible example, step S2 includes: When the working condition is an under-voltage condition, the first threshold value is the minimum value in the specific working interval of the circuit board. For example, the working interval of the fan is A1-A2 (voltage), where A2 is greater than A1, and the under-voltage condition is less than A1. When the working condition is an over-voltage condition, the second threshold value is the maximum value in the specific working interval of the circuit board. For example, the working interval of the fan is A1-A2 (voltage), where A2 is greater than A1, and the over-voltage condition is greater than A2.

[0032] In this embodiment, the specific working interval of the circuit board refers to the working interval in which the circuit board implements its function. For example, for a fan, the working interval of the fan is A1-A2, and the working interval of the circuit board is B1-B2. It can be understood that the working interval of the fan is a subset of the working interval of the circuit board, and the circuit board must be within the working interval of the fan to implement the fan operation function. Therefore, the working interval of the fan is the specific working interval of the circuit board.

[0033] It can be understood that setting the first threshold value as the minimum value of the specific working interval and the second threshold value as the maximum value in the specific working interval can perfectly filter the working interval in which the circuit board implements its function. When the real-time input quantity is a certain value within the specific working interval, the circuit board is in a normal working state, and the output content of the output end of the circuit board is not detected. When the real-time input quantity is less than the first threshold value or greater than the second threshold value, the circuit board is in an abnormal working state, and the circuit board cannot drive the fan to operate. At this time, the identification code output by the embedded software through the output end of the circuit board is received. The embedded software can be identified without disturbing the normal operation of the circuit board.

[0034] It should be noted that the first threshold value can also be greater than the minimum value of the specific working interval, and the second threshold value can also be less than the maximum value of the specific working interval, Optionally, the first threshold is a predetermined multiple of the minimum value, and the predetermined multiple is less than 1. It can be understood that, since the real-time input quantity can fluctuate, in order to reduce the influence of the fluctuation of the real-time input quantity, the first threshold can be set to 80% to 100% of the minimum value of the specific interval, and can be selected according to the real-time input quantity of the circuit board input end. When it is detected that the fluctuation of the real-time input quantity is large, the smaller multiple is selected as much as possible, for example, 0.8 times.

[0035] Optionally, the second threshold is a predetermined multiple of the maximum value, and the predetermined multiple is greater than 1. It can be understood that, since the real-time input quantity can fluctuate, in order to reduce the influence of the fluctuation of the real-time input quantity, the second threshold can be set to 100% to 102% of the minimum value of the specific interval, and can be selected according to the real-time input quantity of the circuit board input end. When it is detected that the fluctuation of the real-time input quantity is large, the larger multiple is selected as much as possible, for example, 1.2 times.

[0036] In a possible example, step S5 comprises: determining an encoding protocol of the identification code, and determining a decoding rule based on the encoding protocol; decoding the identification code according to the decoding rule to determine the information of the embedded software.

[0037] In this step, since the information output by the output end is generally a waveform, the waveform needs to be decoded according to a specific encoding protocol. Optionally, the output waveform adopts Manchester encoding, which is strong in anti-interference and does not need accurate clock synchronization.

[0038] In a possible example, taking an example of the identification code containing version information of the embedded software, the output identification code is 111001011010100000000, the starting bit is agreed to be 3 high pulses (that is, 111), the information bit is agreed to be 8 bits of binary (that is, 00101101 -> version V2.5 of the embedded software), the check bit is agreed to be 2 bits of parity (1 bit in the first 4 bits and 1 bit in the last 4 bits), and the stop bit is agreed to be 1s of low level (that is, 000).

[0039] It should be noted that the selection of the encoding protocol can be selected according to the actual situation, and the use of Manchester encoding is only a possible example, and those skilled in the art can flexibly select under the teaching of the present application.

[0040] In a possible example, the step after step S5 comprises: displaying the information of the embedded software.

[0041] For example, a display unit can be used to display the version number of the decoded embedded software. The display unit can include a display panel, which can be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. It can be understood that the operator can identify the embedded software loaded on the circuit board through the information displayed on the display panel.

[0042] For example, a sound unit can be used to broadcast the version number of the decoded embedded software. After the identification code is decoded, it is converted into audio data, and then the audio data is converted into an electrical signal and transmitted to a loudspeaker. The loudspeaker converts the electrical signal into a sound signal and outputs it. The tester can determine the version of the embedded software through the sound without looking up, thereby further improving the testing efficiency.

[0043] For example, a printing unit can be used to print the version number of the embedded software. For example, after the identification code is decoded, the information corresponding to the embedded software is converted into a recognizable two-dimensional code or a bar code, which is printed by the printing unit. The printed two-dimensional code or bar code can be attached to the circuit board, and the two-dimensional code can be recognized by the code scanning procedure downstream of the flow line, thereby classifying a large number of circuit boards and improving the identification efficiency of the batch circuit boards.
