[0065] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0066] In some of the processes described in the specification and claims of this application and the above-mentioned figures, multiple operations that appear in a specific order are included, but it should be clearly understood that these operations may not be executed in the order in which they appear in this article or executed in parallel. The serial numbers of the operations, such as 101, 102, etc., are only used to distinguish between different operations, and the serial numbers themselves do not represent any execution order. In addition, these processes may include more or fewer operations, and these operations may be executed in sequence or in parallel. It should be noted that the descriptions of "first", "second", etc. in this article are used to distinguish different messages, devices, modules, etc., do not represent the order of precedence, and do not limit the "first" and "second" to be different types.

[0067] The technical solution of the embodiment of the present application can be applied to cleaning equipment with a program burning function, for example, it can be a self-moving cleaning equipment and a handheld cleaning equipment with a program burning function, and the present application does not limit this. For example, in the embodiment of the present application, the cleaning equipment includes but is not limited to a self-moving cleaning equipment and a handheld cleaning equipment. The self-moving cleaning equipment includes: a sweeping robot, a self-moving air purifier, a solar panel cleaning robot, a window cleaning robot, etc. The handheld cleaning equipment includes a handheld cleaning machine, a handheld vacuum cleaner, a handheld vacuum cleaner, a handheld desktop cleaning machine, etc. Usually these cleaning equipment include: a housing, a main motor, a roller brush, a recovery device and a BMS battery management system. The BMS battery management system includes a rechargeable battery, and the housing is provided with a first interface connected to the rechargeable battery.

[0068] The inventors found in their research that most cleaning equipment programs are burned by burning circuit boards. After the program is installed in the whole machine, if the program needs to be reworked, the machine needs to be disassembled or partially disassembled before updating the program. However, this program update method may cause damage to the cleaning equipment, and the efficiency of program updates is not high.

[0069] In addition, current cleaning equipment is usually equipped with two interfaces: a charging interface and a burning interface. When the cleaning equipment needs to update the program, it is necessary to connect to the burning interface of the cleaning equipment to update the program; when the cleaning equipment needs to be charged, it is necessary to switch to the charging interface again to connect to the charging device, resulting in the problem of cumbersome program burning process.

[0070] Therefore, in order to solve the problem that the current program burning method of cleaning equipment requires disassembly for program update resulting in poor program update efficiency, and the problem that the burning interface and the charging interface are not set at the same port resulting in cumbersome program burning process operation.

[0071] After a series of studies, the inventor proposed the technical solution of the present application. The embodiment of the present application provides a cleaning device, which includes a rechargeable battery and a control module; the control module is used to receive an external signal through a first interface; the control module is also used to extract signal energy from the external signal, use the signal energy to power the processor, and send the external signal to the processor. Furthermore, if the control module detects that the external signal is a burning signal, the program is burned based on the burning signal; the control module is also used to connect to a charging device through the first interface; the control module is also used to charge the rechargeable battery in the cleaning device based on the charging signal if the external signal is detected to be a charging signal.

[0072] In this solution, the cleaning device can extract signal energy from an external signal (such as a burning signal or a charging signal), and use the signal energy to power a processor, so that the processor can burn the program based on the burning signal after power-on, thereby ensuring the program burning efficiency of the cleaning device, or charge the rechargeable battery in the cleaning device based on the charging signal, thereby ensuring the charging efficiency of the cleaning device.

[0073] Furthermore, the cleaning equipment provided by the present application converts the serial port signal of the computer device into a burning signal, and burns the program based on the burning signal, thereby avoiding the problem of disassembling the machine for program burning, which not only reduces the damage to the machine caused by disassembly, but also improves the efficiency of program updates; at the same time, the present application sets the charging interface and the burning interface to the same port (that is, the first interface can be a charging interface for connecting a charging device, or a burning interface for connecting a burning device to receive an external signal), so that charging and burning can be achieved by connecting the first interface, thereby solving the problem of cumbersome operation of the program burning process.

[0074] 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 those skilled in the art without creative work are within the scope of protection of this application.

[0075] Figure 1 A schematic diagram of the structure of a program burning system provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the program burning system includes a burning device 1 , a cleaning device 2 and a computer device 3 . The cleaning device 2 is provided with a control module 21 and a first interface 22 connected to the control module 21 .

[0076] The burning device 1 is connected to the computer device 3 and connected to the control module 21 via the first interface 22 , and is used to convert the serial port signal of the computer device 3 into a burning signal recognizable by the control module 21 .

[0077] Wherein, the serial port signal of the computer device 3 may include an RS232 serial port signal or a USB serial port signal. Different serial port signals of the computer device need to be converted by different signal conversion circuits and converted into a burning signal recognizable by the control module 21. The specific conversion process can be referred to in subsequent embodiments. Wherein, the burning signal recognizable by the control module 21 is a Uart serial port signal recognizable by the cleaning device.

[0078] The control module 21 is used to receive an external signal through the first interface 22, extract signal energy from the external signal, use the signal energy to power the processor, and send the external signal to the processor.

[0079] Furthermore, the control module 21 is further configured to perform program burning based on the burning signal if it is detected that the external signal is a burning signal.

[0080] The control module 21 is further configured to connect to the charging device 4 via the first interface 22 , and if the external signal is detected to be a charging signal, the rechargeable battery in the cleaning device is charged based on the charging signal.

[0081] That is, when the control module 21 is connected to the burning device 1, the received external signal is a burning signal; when the control module 21 is connected to the charging device 4, the received external signal is a charging signal.

[0082] In the embodiment of the present application, the external signal may include a burning signal and a charging signal. The control module 21 detects whether the external signal is a burning signal, such as Figure 2As shown, when the detected external signal presents a square wave signal, it is determined that the external signal is a burning signal. Specifically, the control module 21 can identify the voltage of the external signal by judging the voltage recognition method. If it is detected that the voltage of the external signal presents a trend of voltage rising (such as rising to V1) or falling (such as falling to V0) over time T, it is determined that the external signal is a square wave signal, that is, a burning signal.

[0083] In the embodiment of the present application, the control module 21 detects whether the external signal is a charging signal in the following manner: Figure 3 As shown, when the detected external signal presents a stable signal, it is determined that the external signal is a charging signal. Specifically, the control module 21 can identify the voltage of the external signal by voltage recognition. If it is detected that the voltage of the external signal presents a stable trend over time T (such as tending to be stable at voltage V1), it is determined that the external signal is a stable signal, that is, a charging signal.

[0084] In addition, the program burning system provided by the present application is also a program burning system with a single port for charging and burning, that is, the first interface of the present application can be used as both a charging interface and a burning interface, so that when the first interface is connected to the burning device, the cleaning device performs program burning, and when the first interface is connected to the charging device, the cleaning device performs charging. Compared with the existing cleaning equipment that has a charging interface and a burning interface respectively, the program burning system with a single port for charging and burning of the present application can not only solve the problem of cumbersome operation of the program burning process, but also optimize the manufacturing process of the cleaning equipment.

[0085] That is to say, both the burning device and the charging device are connected to the control module 21 through the first interface, thereby realizing the same port setting for charging and burning. By setting the same port for charging and burning, when the cleaning device is burning a program, the charging interface can be used to update the program, or when the cleaning device is charging, the burning interface can be used to power the cleaning device, thereby improving the applicability of the cleaning device.

[0086] Figure 4 Another program burning system provided in an embodiment of the present application includes a burning device 1 , a cleaning device 2 and a computer device 3 . The cleaning device 2 is provided with a control module 21 and a first interface 22 connected to the control module 21 .

[0088] The signal processing module 211 is used to receive an external signal, extract signal energy from the external signal, use the signal energy to power the processor 212 , and send the external signal to the processor 212 .

[0089] In the embodiment of the present application, the external signal may include a charging signal and a burning signal, so the signal processing module 211 collects the signal energy of the burning signal or the charging signal to supply power to the processor.

[0090] The processor 212 is configured to control the burning module 213 to burn a program based on the burning signal if the external signal is detected to be a burning signal.

[0091] In practical applications, the first interface 22 includes a first signal line and a first ground line. The burning device 1 includes a second interface, and the second interface includes a second signal line and a second ground line. The connection method between the cleaning device 2 and the burning device 1 may include: when the burning device 1 is connected to the signal processing module 211 through the first interface 22, the second signal line is connected to the first signal line, and the second ground line is connected to the first ground line;

[0092] Therefore, when the signal processing module 211 of the cleaning device 2 detects that the second signal line 131 is connected to the first signal line and the first ground line is connected to the second ground line, it is determined that the external signal is a burning signal.

[0093] Figure 5 Another program burning system provided in the embodiment of the present application is similar to the above Figure 4 The difference between the program burning system is that the signal processing module 211 of the embodiment of the present application includes a signal input circuit 211a connected to the first interface 22 and an energy extraction circuit 211b connected to the signal input circuit 211a;

[0095] The energy extraction circuit 211 b is used to extract signal energy from the external signal, use the signal energy to power the processor 212 , and send the external signal to the processor 212 .

[0096] Figure 6 Another program burning system provided in the embodiment of the present application is similar to the above Figure 5 The difference between the program burning system is that the burning device 1 of the embodiment of the present application includes a signal conversion module 11 connected to the computer device 3 and a signal output module 12 connected to the signal conversion module 11;

[0097] The signal conversion module 11 is used to convert the serial port signal of the computer device 3 into a burning signal that can be recognized by the control module 21.

[0098] The signal output module 12 is used to send the burning signal to the control module 21 .

[0099] Figure 7 A charging system provided in an embodiment of the present application includes a cleaning device 2 and a charging device 4. The cleaning device 2 is provided with a control module 21 and a first interface 22 connected to the control module. The control module 21 includes a signal processing module 211, a processor 212 connected to the signal processing module 211, and a burning module 213 connected to the processor 212.

[0100] The signal processing module 211 is also used to connect to the charging device 4 through the first interface 22;

[0101] The signal processing module 211 is also used to charge the rechargeable battery in the cleaning device based on the charging signal if the external signal is detected to be a charging signal.

[0102] In practical applications, the first interface 22 includes a first signal line and a first ground line. The charging device 4 includes a positive electrode and a negative electrode. The connection method between the cleaning device 2 and the charging device 4 may include: when the charging device 4 is connected to the signal processing module 211 through the first interface 22, the positive electrode is connected to the first signal line, and the negative electrode is connected to the first ground line.

[0103] Therefore, when the signal processing module 211 of the cleaning device 2 detects that the positive electrode is connected to the first signal line and the negative electrode is connected to the first ground line, it is determined that the external signal is a charging signal.
