[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Combine the following Figure 1-Figure 3 The address determination method of the device provided by the present invention is described. The address determination method of the device provided by the present invention can be applicable to expanded address communication situations. The executor of the method can be an electronic device or an address determination device of the device set in the electronic device. The address determination device of the device can be implemented by software, hardware or a combination of both. Figure 1 FIG. 1 is one of the flow charts of the method for determining the address of a device provided by the present invention, such as Figure 1 As shown, the method includes the following steps.

[0033] Step 101: Create an address mapping table and obtain devices to be detected.

[0034] In this step, the address mapping table includes the corresponding relationship between the detection device and the device address.

[0035] Specifically, the target area is first detected to determine the number of serial communication protocol (Inter-Integrated Circuit, I2C) buses in the target area, and then an address mapping table is created based on the detection device of each I2C and the corresponding device address. The address mapping tables corresponding to each I2C device are independent of each other and do not interfere with each other. Furthermore, the essence of the address mapping table is a data structure between software layers. A part of the hardware storage space or hardware storage device is required at each device of the bus for storage and reading. The main functions of the address mapping table are to store the original address of the device to be detected, store the mapped address of the device to be detected, match the original address with the mapped address, and provide access services. After creating the address mapping table, the device to be detected is obtained.

[0036] Step 102: When the device to be detected does not belong to the detection devices in the address mapping table, register the device to be detected in the address mapping table to obtain an initial mapping table.

[0037] Specifically, when the device to be detected does not belong to the detection devices in the address mapping table, the device to be detected is registered in the address mapping table to obtain an initial mapping table.

[0038] In a specific embodiment, Figure 2 FIG. 2 is a flow chart of the method for determining the address of a device provided by the present invention. Figure 2 As shown, the specific implementation method of registering the device to be detected in the address mapping table and obtaining the initial mapping table includes the following steps.

[0039] Step 201: Determine whether the device to be detected belongs to the detection device in the address mapping table.

[0040] Specifically, it is determined whether the device to be detected belongs to the detection device in the address mapping table. If the device to be detected belongs to the detection device in the address mapping table, step 202 is continued; if the device to be detected does not belong to the detection device in the address mapping table, step 203 is continued.

[0041] Exemplarily, if the address mapping table contains detection device A, detection device B, and detection device C, if the device to be detected is A, it is determined that the device to be detected belongs to the detection device A in the address mapping table, and step 202 is continued; if the address mapping table contains detection device A, detection device B, and detection device C, if the device to be detected is D, it is determined that the device to be detected D does not belong to the detection device in the address mapping table, and step 203 is continued.

[0042] In a specific embodiment, before determining whether the device to be detected belongs to the detection device in the address mapping table, it also includes: determining whether the device to be detected is detected, if it is determined that the device to be detected is not detected, then terminating the detection, and determining that all devices on the I2C bus have completed the detection. If it is determined that the device to be detected is detected, then executing step 201.

[0043] Step 202: Determine the target addressing communication address corresponding to the device to be detected according to the address mapping table.

[0044] Specifically, when the device to be detected is a detection device in the address mapping table, it is determined that the device to be detected is not a new I2C device, and therefore the target addressing communication address corresponding to the device to be detected is directly determined according to the address mapping table.

[0045] Step 203: register the device to be detected in the address mapping table, and determine whether the device to be detected is a target address device.

[0046] In this step, the target address device is a preset device, for example, a 7-bit device, which is not limited in this embodiment.

[0047] Specifically, when the device to be detected does not belong to the detection device in the address mapping table, the new device to be detected is registered in the address mapping table, so as to update the address mapping table, and further determine whether the device to be detected is the target address device; if it is determined that the device to be detected is the target address device, continue to execute step 204; if it is determined that the device to be detected is not the target address device, determine that the device to be detected is other address devices, for example, it can be a 10-bit address device, and continue to execute step 206.

[0048] Step 204: Determine whether the device address of the device to be detected overlaps with the address of the registered device that has completed registration in the address mapping table.

[0049] Specifically, when the device to be detected is the target address device, determine whether the device address of the device to be detected has an address duplication with the registered device that has been registered in the address mapping table. If it is determined that the device address of the device to be detected has an address duplication with the registered device that has been registered in the address mapping table, continue to step 205; if it is determined that the device address of the device to be detected has no address duplication with the registered device that has been registered in the address mapping table, continue to step 206.

[0050] Step 205: Map the addresses with duplicate addresses to device addresses to obtain an initial mapping table.

[0051] Specifically, when the device address of the device to be detected overlaps with the registered device registered in the address mapping table, the duplicated address is mapped to a new device address to obtain an initial mapping table, and the process returns to step 201 to determine whether the device to be detected belongs to the detection device in the address mapping table.

[0052] Step 206: Update the target address device according to the device address of the device to be detected, complete the detection and registration of the device to be detected, and obtain an initial mapping table.

[0053] Specifically, when the device to be detected is not the target address device, the target address device is updated according to the device address of the device to be detected, the detection and registration of the device to be detected is completed, the initial mapping table is obtained, and the process returns to step 201 of determining whether the device to be detected belongs to the detection device in the address mapping table.

[0054] Step 103: Acquire the application layer calling file interface and the message data sent by the device to be detected on the bus.

[0055] In this step, the application layer calling the file interface may be, for example, the application layer calling the I2C file interface, and the device to be detected on the bus may be, for example, an I2C hardware device on the bus, which is not limited in this embodiment.

[0056] The message data may be, for example, temperature data of a temperature sensor, humidity data of a humidity sensor, pressure data of a pressure sensor, storage data of a memory, etc., which is not limited in this embodiment.

[0057] Specifically, the application layer calls the file interface and the message data sent by the device to be detected on the bus, such as the temperature data of the temperature sensor, the humidity data of the humidity sensor, the pressure data of the pressure sensor, the storage data of the memory, etc., are obtained.

[0058] Step 104: Mapping and reverse mapping are performed according to the message data and the device address in the initial mapping table to obtain the target addressing communication address corresponding to the device to be detected.

[0059] Specifically, after obtaining the message data, the data address of the message data transmission is checked according to the message data, and then the data address is mapped with the device address in the initial mapping table, and the mapped address is re-encapsulated to determine the encapsulated mapping message. Reverse mapping is performed according to the encapsulated mapping message and the device address in the initial mapping table, and the reverse mapped address is re-encapsulated to obtain the target addressing communication address corresponding to the device to be detected.

[0060] The invention provides a device address determination method, which is to create an address mapping table and obtain a device to be detected; wherein the address mapping table contains a corresponding relationship between the detection device and the device address; when the device to be detected does not belong to the detection device in the address mapping table, the device to be detected is registered in the address mapping table to obtain an initial mapping table; the application layer calls the file interface and the message data sent by the device to be detected on the bus is obtained; mapping encapsulation and reverse mapping encapsulation are performed according to the message data and the device address in the initial mapping table to obtain the target addressing communication address corresponding to the device to be detected. The technical scheme of the invention is used to solve the defect that the prior art can only support addressing of I2C devices with 7-bit addresses, so when facing the situation that a 10-bit address device is mounted on the bus, it will not be possible to achieve addressing communication of all devices on the bus, and the target addressing communication address corresponding to the device to be detected is obtained by obtaining the message data sent by the application layer calling the file interface and the device to be detected on the bus; mapping encapsulation and reverse mapping encapsulation are performed according to the message data and the device address in the initial mapping table to obtain the target addressing communication address corresponding to the device to be detected, so as to determine the target addressing communication address of the device to be detected with different addresses, and meet the addressing of the device to be detected with different addresses.

[0061] Figure 3This is the third flow chart of the device address determination method provided by the present invention. The device address determination method provided by the present invention can be applied to the expansion of address communication conditions. The execution subject of this method can be an electronic device or a device address determination device set in the electronic device. The device address determination device can be implemented by software, hardware or a combination of the two. Figure 3 As shown, mapping encapsulation and reverse mapping encapsulation are further performed on the message data and the device address in the initial mapping table to obtain the target addressing communication address corresponding to the device to be detected and optimize the method, which includes the following steps.

[0062] Step 301: Create an address mapping table and obtain devices to be detected.

[0063] In this step, the address mapping table includes the corresponding relationship between the detection device and the device address.

[0064] Specifically, the target area is first detected to determine the number of serial communication protocol (Inter-Integrated Circuit, I2C) buses in the target area, and then an address mapping table is created based on the detection device of each I2C and the corresponding device address. The address mapping tables corresponding to each I2C device are independent of each other and do not interfere with each other. Furthermore, the essence of the address mapping table is a data structure between software layers. A part of the hardware storage space or hardware storage device is required at each device of the bus for storage and reading. The main functions of the address mapping table are to store the original address of the device to be detected, store the mapped address of the device to be detected, match the original address with the mapped address, and provide access services. After creating the address mapping table, the device to be detected is obtained.

[0065] Step 302: When the device to be detected does not belong to the detection devices in the address mapping table, register the device to be detected in the address mapping table to obtain an initial mapping table.

[0066] Specifically, when the device to be detected does not belong to the detection device in the address mapping table, the device to be detected is registered in the address mapping table; when the device to be detected does not belong to the detection device in the address mapping table, a new device to be detected is registered in the address mapping table, thereby updating the address mapping table and further determining whether the device to be detected is the target address device; if it is determined that the device to be detected is the target address device, it is determined whether the device address of the device to be detected is duplicated with the registered device registered in the address mapping table; when the device address of the device to be detected is duplicated with the registered device registered in the address mapping table, the address with the duplicated address is mapped to a new device address to obtain an initial mapping table.

[0067] Step 303: Acquire the application layer calling file interface and the message data sent by the device to be detected on the bus.

[0068] Specifically, the application layer calls the file interface and the message data sent by the device to be detected on the bus, such as the temperature data of the temperature sensor, the humidity data of the humidity sensor, the pressure data of the pressure sensor, the storage data of the memory, etc., are obtained.

[0069] Step 304: Map and encapsulate the message data and the device address in the initial mapping table to obtain a mapping message.

[0070] In a specific implementation, mapping and encapsulating are performed according to the message data and the device address in the initial mapping table to obtain the specific implementation steps of the mapping message, including: unpacking the message data to determine the data address corresponding to the data information of the device to be detected; mapping is performed according to the data address and the device address in the initial mapping table to obtain the mapping address; and message encapsulation is performed on the mapping address to obtain the mapping message.

[0071] Specifically, the message data is unpacked. According to the I2C standard protocol, the information contained in the first byte or the second byte is the message address of the message data, so as to check the message address of the message data, and then, the data address and the device address in the initial mapping table are mapped to obtain the mapping address; the mapping address is message encapsulated to obtain a mapping message.

[0072] Step 305: reverse mapping and encapsulating the mapping message and the device address in the initial mapping table to obtain the target addressing communication address corresponding to the device to be detected.

[0073] In a specific implementation, the mapping message and the device address in the initial mapping table are reverse mapped and encapsulated, and the specific implementation steps for obtaining the target addressing communication address corresponding to the device to be detected include: extracting the address according to the mapping message and determining the message transmission address; wherein the message transmission address is used to determine the transmission address of the mapping message; reverse mapping and encapsulating the device address of the message transmission address in the initial mapping table to determine the target addressing communication address.

[0074] Specifically, the message transmission address of the mapping message is checked according to the message packet header of the mapping message, the address is extracted to obtain the message transmission address, the device address of the message transmission address in the initial mapping table is reversely mapped and encapsulated to determine the target addressing communication address.

[0075] The invention provides a device address determination method, which is implemented by creating an address mapping table and obtaining a device to be detected; in the case where the device to be detected does not belong to the detection device in the address mapping table, registering the device to be detected in the address mapping table to obtain an initial mapping table; obtaining the application layer calling the file interface and the message data sent by the device to be detected on the bus; mapping and encapsulating according to the message data and the device address in the initial mapping table to obtain a mapping message; reverse mapping and encapsulating the mapping message and the device address in the initial mapping table to obtain the target addressing communication address corresponding to the device to be detected. The technical scheme of the invention is used to solve the defect that the prior art can only support addressing of I2C devices with 7-bit addresses, so when a 10-bit address device is mounted on the bus, it will not be possible to achieve addressing communication of all devices on the bus, and achieves by obtaining the application layer calling the file interface and the message data sent by the device to be detected on the bus; mapping and encapsulating according to the message data and the device address in the initial mapping table and reverse mapping and encapsulating to obtain the target addressing communication address corresponding to the device to be detected, and achieving the determination of the target addressing communication address of the device to be detected with different addresses, so as to meet the addressing of the device to be detected with different addresses.
