[0066] Figure 3b This is a schematic structural diagram of a device for instruction transmission applied to a device disclosed in an embodiment of the present application. Detailed implementation manners

[0067] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0068] Embodiment 1: The present application discloses a method for instruction transmission.

[0069] Specifically, please refer to Figure 1 In a method for instruction transmission disclosed in this embodiment, the method applied to the control module includes the following steps:

[0070] Step 101: Generate a data packet based on the instruction and the corresponding relationship between the instruction and multiple devices.

[0071] In the method of this embodiment, the instruction is used to indicate the operation of the device. When there are multiple devices, the instruction needs to indicate the operations of multiple devices, so there is a corresponding relationship with multiple devices. And in the case where multiple devices perform different operations, the instruction can indicate different devices to perform different operations. For example, it indicates that device 1 performs a first operation and device 2 performs a second operation.

[0072] As an alternative method, an index file can be generated in advance according to the device identifiers of multiple devices. Multiple positions in the index file correspond one-to-one with multiple device identifiers. Then, the requirements of the instruction for each device are added to the index file to obtain the corresponding relationship. The requirement can specifically be to control the device to execute the instruction or to control the device to ignore the instruction. Taking eight devices as an example, the corresponding relationship can be in the form of a binary bit mask, such as a bit mask with a length of 8 bits. Each bit mask corresponds to each device one-to-one. Specifically, for example, the bit mask is 10110010 (binary), the first bit mask "1" corresponds to device 8, the second bit mask "0" corresponds to device 7, and so on, and the last bit mask "0" corresponds to device 1. Of course, in an actual working scenario, the length of the bit mask can be set according to the number of devices, and the order of the bit mask and its corresponding relationship with the devices can also be set according to actual requirements. The example here is only for easy understanding and does not serve as a limitation. As another alternative method, the corresponding relationship can be in the form of an index table, which is used for a lookup table structure, and each position in the table is corresponded with the number of a device.

[0073] In the method of this embodiment, the value of the bitmask can indicate whether the device executes the instruction or ignores it. For example, the value 1 indicates that the device executes the instruction, and the value 0 indicates that the device ignores the instruction. For the bitmask in the above example, it can be known that devices 8, 6, 5, and 2 need to execute the instruction, and devices 7, 4, 3, and 1 need to ignore the instruction.

[0074] In the method of this embodiment, since an instruction can direct multiple devices to perform different operations, the instruction can be an instruction code. For example, it can direct a device to perform a start operation or a shutdown operation. As an alternative method, the length of the instruction code can be 16 bits, including an operation code (the high 8 bits) and a parameter code (the low 8 bits). Among them, the operation code (in hexadecimal) and its meaning can be: 0x01 represents starting the motor, 0x02 represents stopping the motor, 0x03 represents adjusting the temperature, etc. The parameter code is used to represent the parameters of the action indicated by the operation code. For example, when the operation code is 0x01, the parameter code can be 0x01 (in hexadecimal), indicating that the motor speed is 100%. Another example is when the operation code is 0x03, the parameter code indicates the temperature value.

[0075] As an alternative method, by combining the correspondence and the instruction, that is, by combining the bitmask and the instruction code, a data packet can be generated. Considering data security issues, an encryption field can also be added to the bitmask or the instruction code to enhance security.

[0076] As another alternative method, based on the bitmask and the instruction code, an error correction code can be generated first, and then the bitmask, the instruction code, and the error correction code can be combined to generate a data packet, that is, by combining the correspondence, the instruction, and the error correction code in sequence to obtain the data packet. Among them, the error correction code is used to detect and correct errors during transmission. It is specifically calculated based on the bitmask and the instruction code. Among them, the error correction code can be based on the Hamming code to handle single-bit errors, or based on the Reed-Solomon code to handle consecutive multi-bit errors.

[0077] As an alternative method, corresponding to the bitmask and the instruction code in the above example, the first 24-bit data is 10110010 00000001 01100100 (binary), that is, 0xB2 0x01 0x64 (hexadecimal). The Hamming code of the first 24-bit data can be calculated to obtain the error correction code as 00111010 (binary), that is, 0x3A (hexadecimal).

[0078] Step 102: Broadcast the data packet to multiple devices.

[0079] In the method of this embodiment, the control module broadcasts the data packet to multiple devices in the form of wireless communication. The data packet is used to enable the multiple devices to execute or ignore the instruction based on the data packet. As an alternative method, when receiving the data packet, the device may first perform an integrity check to obtain a check result. When the check result is normal, the device executes or ignores the instruction based on the data packet. When the check result is abnormal, the device searches for an error correction code in the data packet. When there is no error correction code in the data packet, the device returns an abnormal error message. When there is an error correction code in the data packet, the device corrects the instruction and the corresponding relationship based on the error correction code to obtain the correct instruction and the correct corresponding relationship. Then, according to the correct instruction and the correct corresponding relationship, the device executes or ignores the instruction.

[0080] As an alternative method, the error correction process may specifically be, for example, the length of the data packet is 32 bits, which includes a 24-bit bit mask and instruction code, and an 8-bit error correction code. When receiving the data packet, in the case of 1-bit error caused by noise or the like, the 12th bit in the received data changes from the original data 0 to 1. At this time, the device can calculate the Hamming code of the first 24 bits of the received data to obtain a verification code. Comparing this verification code with the error correction code can locate the error bit, that is, the 12th bit, and change the value on it to 0 to obtain the first 24-bit data, that is, the correct bit mask and instruction code.

[0081] In the method of this embodiment, after the broadcast ends, the control module can also receive feedback information sent back from multiple devices. The feedback information indicates that the device has executed or ignored the instruction.

[0082] In a method for transmitting instructions disclosed in this embodiment, the method applied to the device includes the following steps:

[0083] Step 103: Receive a broadcast message from the control module and obtain the data packet.

[0084] In the method of this embodiment, when there is an error correction code in the data packet, after receiving the data packet, the device may first perform an integrity check on the data packet. When the check result obtained from the integrity check is abnormal, the device can correct the instruction and the corresponding relationship based on the error correction code according to the method in step 102 to obtain the correct instruction and the correct corresponding relationship.

[0085] Step 104: Execute or ignore the instruction based on the corresponding relationship and the device identifier.

[0086] In the method of this embodiment, a unique device identifier is assigned to the device during factory production or deployment, and this device identifier is stored in the built-in memory of the device. The device can look up the position corresponding to the device identifier in the index file in the correspondence relationship, and then execute the instruction according to the requirements of the position or control the device to ignore the instruction. That is, the device can determine the bit mask corresponding to itself in the data packet according to its own device identifier, and then independently judge whether to execute the instruction according to the value of the bit mask. For example, corresponding to the above example, device 8 determines that the bit mask corresponding to itself is the first bit mask, and its value is "1", then device 8 executes the instruction. Device 7 determines that the bit mask corresponding to itself is the second bit mask, and its value is "0", then device 7 does not execute the instruction.

[0087] In the method of this embodiment, after the device executes or ignores the instruction, the feedback information can also be sent back to the control module.

[0088] The method described in this embodiment supports the device to locate the bit mask corresponding to itself in the data packet through its own identifier, and independently judge whether to execute the instruction according to its value. It can broadcast a unified instruction to all devices at one time, and can also accurately select some devices to control them. It realizes the directional control effect under broadcasting, combines the advantages of both, realizes efficient transmission, and meets the need for precise control of specific devices. Applied to a multi-device system, it solves the problems of time-consuming and complex operation caused by sending instructions to some target devices one by one in the traditional unicast mode, and realizes the efficient transmission of instructions.

[0089] Embodiment 2: The present application discloses another method for instruction transmission. Please refer to Figure 2 , and the method described in this embodiment introduces the whole process of instruction transmission.

[0090] Step 201: The control module generates a data packet.

[0091] Step 202: The control module sends the data packet to the first device.

[0092] Step 203: The first device performs an integrity check on the data packet to determine whether the check result is normal. If so, go to step 204; if not, go to step 205.

[0093] Step 204: The first device determines the corresponding bit mask in the data packet based on its own device identifier.

[0094] Step 205: The first device corrects the data packet based on the error correction code in the data packet. And go to step 204.

[0095] Step 206: The first device determines whether the value of the bit mask is 1. If so, go to step 207; if not, go to step 208.

[0096] Step 207: The first device executes the instruction code in the data packet.

[0097] Step 208: The first device ignores the instruction code in the data packet.
