[0055] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0056] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0058] In a group control system, the master device needs to send a command to at least one slave device and execute the command simultaneously with the slave device. However, due to network transmission time-consuming reasons, there will be a delay in the time when the slave device receives the command, resulting in the master device and the slave device being unable to execute the command at the same time. In related technologies, the master device and the slave device can execute the command at the same time at a certain time after the delay time, but due to geographical and device issues, the time displayed on different devices may be different. Therefore, the master device and the slave device cannot guarantee that the command will be executed at the same time.

[0059] Based on this, the embodiments of the present application provide an instruction execution method, device, electronic device and storage medium, which are intended to adjust the count value of the first system timer on the master device and the count value of the second system timer on the slave device, so that the adjusted count values ​​of the first system timer and the second system timer are the same. Obtain the target sending count value and the target delay count value, and determine the device execution count value according to the target sending count value, the target delay count value and the pre-designed value. When the count value of the first system timer reaches the pre-designed value, the target instruction and the device execution count value are sent to each slave device, and the slave device can receive the target instruction before the second system timer reaches the device execution count value. The first system timer and the second system count value can also reach the device execution count value at the same time, and the master device and the slave device execute the target instruction at the same time when they reach the device execution count value, which solves the problem that the master device and the slave device cannot guarantee the execution of instructions at the same time point.

[0065] Please refer to Figure 1 , Figure 1 It is an optional flowchart of the instruction execution method provided in an embodiment of the present application. The instruction execution method is applied to a master device, the master device is communicatively connected to at least one slave device, a first system timer is set on the master device, and a second system timer is set on the slave device. Figure 1 The method may include but is not limited to steps S101 to S107.

[0066] Step S101, obtaining a current count value of a first system timer to obtain a first count value, and obtaining a current count value of each second system timer to obtain at least one second count value;

[0067] Step S102, adjusting the count values ​​of the first system timer and the second system timer respectively according to the first count value and the second count value; wherein the count values ​​of the first system timer and the second system timer after adjustment are the same;

[0068] Step S103, obtaining instruction sending mode information, and determining a target sending count value according to the instruction sending mode information; wherein the target sending count value is a count value required for the master device to send the instruction to all slave devices;

[0069] Step S104, obtaining a target delay count value; wherein the target delay count value is a maximum delay count value required for the master device to send an instruction to each slave device;

[0070] Step S105, determining the device execution count value according to the target sending count value, the target delay count value and the pre-designed value; wherein the pre-designed count value is the count value of the first system timer when sending the target instruction;

[0071] Step S106, generating a target instruction, and when the count value of the first system timer reaches a pre-designed value, sending the target instruction and the device execution count value to each slave device, so that the slave device executes the target instruction when the count value of the second system timer reaches the device execution count value;

[0072] Step S107, executing the target instruction when the count value of the first system timer reaches the device execution count value.

[0073] In step S101 of some embodiments, the master device is connected to at least one slave device via Bluetooth, ZigBee technology, etc., and the system timer may be a System timer, also known as a system tick timer, which is a counting timer. When the hardware and software in the communication modules of the master device and the slave device are the same, the error between the system tick frequencies is further reduced. Therefore, the counting of the system timer is more accurate than the system time on the device.

[0074] It should be noted that due to regional and device issues, the current count values ​​of system timers on different devices may be different. In order to make the adjusted count values ​​of the first system timer and the second system timer the same, it is necessary to know the current count value of the first system timer and the current count value of each second system timer at the same time. Therefore, the current count value of the first system timer is obtained to obtain the first count value, and the current count value of each second system timer is obtained to obtain the second count value. For example, at the same time, the current count value of the first system timer of the master device is 30, then the first count value is 30, the current count value of the second system timer a of the slave device a is 40, then the second count value a is 40, and the current count value of the second system timer b of the slave device b is 20, then the second count value b is 20.

[0075] In step S102 of some embodiments, the count values ​​of the first system timer and the second system timer are uniformly adjusted to the same value, so that the first system timer and the second system timer can reach the device execution count value at the same time. For example, the count values ​​are uniformly adjusted to 35, or uniformly adjusted to the count value of the first count value or the second count value. Continuing with the above example, at the same time, the count values ​​of the first system timer, the second system timer a and the second system timer b are uniformly adjusted to 35. Then the count value of the first system timer needs to be increased by 5, the count value of the second system timer a needs to be reduced by 5, and the count value of the third system timer b needs to be increased by 15. The specific adjustment method is not limited here.

[0076] In step S103 of some embodiments, after the count values ​​of the first system timer and the second system timer are uniformly adjusted to 35, if the master device sends a target instruction to the slave device, it takes 5 count values ​​for the slave device to receive the target instruction, but the device execution count value is 38, which will result in the master device and the slave device being unable to execute the instructions at the same time. Therefore, the device execution count value needs to be the count value after all devices have received the target instruction.

[0077] Specifically, if the count value required by the master device to send the instruction to all slave devices is 10, the target sending count value is 10. Depending on the instruction sending mode, the target sending count value will also be different. For example, if the instruction sending mode is a broadcast sending mode, the count value required by the master device to send the instruction to all slave devices is 0, and the target sending count value is 0. In this embodiment, the instruction sending mode is determined according to the instruction sending mode information.

[0078] In step S104 of some embodiments, for each slave device, the delay count value required for the master device to send the target instruction to the slave device and for the slave device to receive the target instruction is different. The delay count values ​​of all slave devices are polled and calculated, and the maximum delay count value is obtained by sorting, and the target delay count value is the maximum delay count value.

[0079] In step S105 of some embodiments, after the count values ​​of the first system timer and the second system timer are adjusted, the target instruction can be sent when the count value of the first system timer reaches a pre-designed value, and the pre-designed value is greater than or equal to the count value after the adjustment of the first system timer. The device execution count value is greater than or equal to the sum of the target sending count value, the target delay count value and the pre-designed value. Continuing with the above example, the count values ​​of the first system timer, the second system timer a and the second system timer b are uniformly adjusted to 35. If the pre-designed value is also 35, the target sending count value is 0, and the target delay count value is 5, then the device execution count value can be 40.

[0080] In steps S106 to S107 of some embodiments, the master device generates a target instruction, and when the count value of the first system timer reaches a pre-designed value, the target instruction and the device execution count value are sent to each slave device, so that the slave device executes the target instruction when the count value of the second system timer reaches the device execution count value. The master device also executes the target instruction when the count value of the first system timer reaches the device execution count value. For example, the device execution count value may be 40, and when the count value of the second system timer reaches 40, the slave device executes the target instruction. When the count value of the first system timer reaches 40, the master device executes the target instruction. Since the count value of the first system timer and the count value of the second system timer simultaneously change from the same count value to the device execution count value, the count value of the first system timer and the count value of the second system timer simultaneously reach the device execution count value, thereby achieving the simultaneous execution of the target instruction by the master device and the slave device.

[0081] In the steps S101 to S107 shown in the embodiment of the present application, the first count value is obtained by obtaining the current count value of the first system timer, and the current count value of each second system timer is obtained to obtain at least one second count value. The count values ​​of the first system timer and the second system timer are adjusted according to the first count value and the second count value, respectively, wherein the count values ​​of the first system timer and the second system timer after adjustment are the same. The target sending count value is determined according to the instruction sending mode information; wherein the target sending count value is the count value required for the master device to send the instruction to all slave devices. The target delay count value is obtained; wherein the target delay count value is the maximum delay count value required for the master device to send the instruction to each slave device. The device execution count value is determined according to the target sending count value, the target delay count value and the pre-designed value. The target instruction is generated, and when the count value of the first system timer reaches the pre-designed value, the target instruction and the device execution count value are sent to each slave device, and the slave device executes the target instruction when the count value of the second system timer reaches the device execution count value. The master device executes the target instruction when the count value of the first system timer reaches the device execution count value. In this embodiment, the system timers of the master device and the slave device can reach the device execution count value at the same time, and execute the target instruction at the same time when the count value of the system timer reaches the device execution count value, thereby solving the problem that the master device and the slave device cannot guarantee the execution of instructions at the same time point.

[0082] See also Figure 2 In some embodiments, step S102 may include but is not limited to steps S201 to S202:

[0083] Step S201, selecting a count value according to a first count value and at least one second count value to obtain a target count value;

[0084] Step S202: adjusting the count values ​​of the first system timer and the second system timer respectively according to the target count value.

[0085] In step S201 of some embodiments, when the count values ​​after adjustment of the first system timer and the second system timer are not selected from the first count value and the second count value, the count of each system timer needs to be adjusted. Therefore, in order to reduce the number of adjustments, the count value selection can be performed on the first count value and at least one second count value to obtain a target count value, and then the count values ​​of the first system timer and the second system timer are adjusted based on the target count value.

[0086] Specifically, the counting value selection method can be to use the maximum / minimum counting value as the target counting value, or to use the counting value with the largest number as the target counting value. For example, if the first counting value is 25, the second counting value a is 40, and the second counting value b is 25, then the counting value with the largest number is 25, and the target counting value is 25.

[0087] In step S202 of some embodiments, the count values ​​of the first system timer and the second system timer are adjusted according to the target count value, and when the target count value is equal to the first count value or the second count value, there is no need to adjust the corresponding system timer, thereby reducing the number of adjustments. The above example is used for illustration, and when the target count value is equal to the first count value and the second count value b, there is no need to adjust the first system timer and the second system timer b, and only the count value of the second system timer a corresponding to the second count value a needs to be adjusted.

[0088] In steps S201 to S202 shown in this embodiment, a target count value is obtained by selecting a count value according to the first count value and at least one second count value, and the count values ​​of the first system timer and the second system timer are adjusted respectively according to the target count value, thereby reducing the number of adjustments.

[0089] See also Figure 3 In some embodiments, step S202 may include but is not limited to steps S301 to S303:

[0090] Step S301, obtaining a difference between a target count value and a first count value to obtain a first difference value;

[0091] Step S302, obtaining a difference between the target count value and the second count value to obtain a second difference value;

[0092] Step S303: adjusting the count value of the first system timer according to the first difference, and adjusting the count value of the second system timer according to the second difference.

[0093] In steps S301 to S302 of some embodiments, since the count value of the system timer changes in real time, when adjusting the count values ​​of the first system timer and the second system timer respectively according to the target count value, the first system timer is adjusted according to the difference between the target count value and the first count value, and the second system timer is adjusted according to the difference between the target count value and the second count value. Therefore, the difference between the target count value and the first count value is obtained to obtain the first difference, and then the difference between the target count value and the second count value is obtained to obtain the second difference.

[0094] In step S303 of some embodiments, if the first count value is 30, the second count value a is 40, and the second count value b is 20, the largest count value is selected as the target count value, so the target count value is 40. Then the first difference between the target count value and the first count value is 10, indicating that the count value of the first system timer needs to be increased by 10 count values. The second difference between the target count value and the second count value a is 0, indicating that the count value of the second system timer a does not need to be adjusted. The second difference between the target count value and the second count value b is 20, indicating that the count value of the second system timer b needs to be increased by 20 count values. During the adjustment, 5 count values ​​have passed, and the current count value of the first system timer is 35. After increasing by 10 count values, the current count value of the first system timer is 45. Since 5 count values ​​have passed, the current count value of the second system timer a is also 45. The current count value of the second system timer b is 25. After increasing by 20 count values, the current count value of the second system timer b is also 45. Therefore, after the adjustment, the count values ​​of the first system timer, the second system timer a, and the second system timer b are the same.

[0095] In steps S301 to S303 of this embodiment, by acquiring the first difference and the second difference, the count value of the first system timer can be adjusted based on the first difference, and the count value of the second system timer can be adjusted based on the second difference.

[0096] See also Figure 4 In some embodiments, step S101 may include but is not limited to steps S401 to S404:

[0097] Step S401, sending a query instruction to the slave device, and recording the count value of the first system timer when sending the query instruction to obtain a first count value;

[0098] Step S402, receiving a first message returned by the slave device according to the query instruction; wherein the first message includes a third count value, and the third count value is a count value of the second system timer when the slave device receives the query instruction;

[0099] Step S403, acquiring a count value of the first system timer when the first message is received, to obtain a fourth count value;

[0100] Step S404, determining a second count value according to the first count value, the third count value and the fourth count value.

[0101] In step S401 of some embodiments, when the master device needs to obtain the second count value of the slave device, it needs to send a query instruction to the slave device, and the count value of the first system timer is the first count value when the query instruction is sent.

[0102] In step S402 of some embodiments, after receiving the query instruction, the slave device returns a first message to the master device, the first message includes a third count value, and the third count value is the count value of the second system timer when the slave device receives the query instruction.

[0103] In steps S403 to S404 of some embodiments, after receiving the first message, the master device records the count value of the first system timer when the first message is received to obtain a fourth count value, thereby determining the second count value based on the first count value, the third count value and the fourth count value.

[0104] Specifically, the delay count value for the master device to send a query instruction to the slave device can be determined based on the first count value and the fourth count value. For example, if the master device sends a query instruction to the slave device when the count value of the first system timer is 30, the first count value is 30. When the slave device receives the query instruction, the count value of the second system timer is 42, the third count value is 42, and the slave device returns a first message to the master device, and the first message includes the third count value. When the master device receives the first message, the count value of the first system timer is 34, the fourth count value is 34, and the delay count value is (34-30) / 2=2. Since the third count value is 42, it means that when the first count value is 30, the second count value is 42-2=40, thereby obtaining the second count value.

[0105] It should be noted that if the second count values ​​of multiple slave devices need to be obtained, query instructions are sent to multiple slave devices at the same time. For example, when the second count values ​​of two slave devices are obtained at the same time, the master device sends a query instruction to slave device a and slave device b when the count value of the first system timer is 30, and the first count value is 30. When slave device a receives the query instruction, the count value of the second system timer a is 42, and the third count value a is 42. When slave device b receives the query instruction, the count value of the second system timer b is 23, and the third count value b is 23. Slave device a returns a first message a to the master device, and the first message a includes the third count value a. When the master device receives the first message a, the count value of the first system timer is 34, and the fourth count value a is 34, and the delay count value is (34-30) / 2=2. Since the third count value a is 42, it means that when the first count value is 30, the second count value a is 42-2=40, thereby obtaining the second count value a. Slave device b returns a first message b to the master device, and the first message b includes the third count value b. When the master device receives the first message b, the count value of the first system timer is 36, then the fourth count value b is 36, and the delay count value is (36-30) / 2=3. Since the third count value b is 23, it means that when the first count value is 30, the second count value is 23-3=20, so the second count value b is 20. The method for obtaining the second count values ​​of three or more slave devices is similar to the above, and will not be repeated here.

[0106] In steps S401 to S404 of this embodiment, by determining the first count value and the second count value, the count values ​​of the first system timer and the second system timer can be adjusted based on the first count value and the second count value, so that the adjusted count values ​​of the first system timer and the second system timer are the same.

[0107] See also Figure 5 In some embodiments, the instruction sending mode information includes polling sending mode information or broadcast sending mode information, and step S103 includes but is not limited to steps S501 to S502:

[0108] Step S501, if the instruction sending mode information is the polling sending mode information, then obtain the sending interval count value of sending instructions to each slave device, and determine the target sending count value according to each sending interval count value;

[0109] Step S502: If the instruction sending mode information is the broadcast sending mode information, the target sending count value is zero.

[0110] In step S501 of some embodiments, the polling transmission mode is that the master device sends the instruction to each slave device when the first system timer is a different count value. If the instruction transmission mode is the polling transmission mode, the sum of all transmission interval count values ​​is the target transmission count value. Among them, the transmission interval count values ​​are generally set to be equal. When the transmission interval count values ​​are all 2 count values, if there are a total of 5 slave devices, the target transmission count value is 8.

[0111] In step S502 of some embodiments, the broadcast transmission mode is that the master device simultaneously sends the instruction to each slave device by broadcasting, and the target transmission count value is zero.

[0112] In step S501 to step S502 shown in this embodiment, different instruction sending modes have different target sending count values. By acquiring the instruction sending mode information, the target sending count value can be determined.

[0113] See also Figure 6 In some embodiments, step S104 may include but is not limited to steps S601 to S604:

[0114] Step S601, sending a test instruction to each slave device, and recording the count value of the first system timer when sending the test instruction to obtain a fifth count value;

[0115] Step S602, receiving a second message returned by the slave device according to the test instruction, and recording the count value of the first system timer when the second message is received to obtain a sixth count value;

[0116] Step S603, determining a delay count value of the slave device according to the fifth count value and the sixth count value, and obtaining a candidate delay count value;

[0117] Step S604: sort each candidate delay count value, and the largest candidate delay count value is the target delay count value.

[0118] In step S601 of some embodiments, since the device execution count value is determined based on the target delay count value, the target delay count value is acquired in advance. The target delay count value is the maximum delay count value required for the master device to send the instruction to each slave device. Therefore, a test instruction must be sent to each slave device, and the count value of the first system timer when the test instruction is sent is recorded to obtain the fifth count value. When the master device sends the test instruction to the slave device, the count value of the first system timer is 35, then the fifth count value is 35.

[0119] In steps S602 to S603 of some embodiments, after receiving the test instruction, the slave device returns a second message to the master device. The master device records the count value of the first system timer when receiving the second message to obtain a sixth count value. The delay count value of the slave device can be determined based on the fifth count value and the sixth count value. For example, if the fifth count value is 35 and the count value of the first system timer is 39 when the master device receives the second message, then the sixth count value is 39, and the candidate delay count value of the slave device is (39-35) / 2=2.

[0120] In step S604 of some embodiments, the maximum candidate delay count value is used as the target delay count value. It should be noted that the test instruction can be sent to each slave device at the same time, or the test instruction can be sent to each slave device in a time-sharing manner. For example, if there are only two slave devices, namely slave a and slave b, if the fifth count value a and the fifth count value b are both 35, the sixth count value a is 39, and the sixth count value b is 41. Then the selected delay count value a is 2, the selected delay count value b is 3, and the target delay count value is 3. If the fifth count value a is 35, the fifth count value b is both 40, the sixth count value a is 39, and the sixth count value b is 46. Then the selected delay count value a is 2, the selected delay count value b is 3, and the target delay count value is 3.

[0121] In steps S601 to S604 shown in this embodiment, the fifth count value and the sixth count value are obtained, thereby obtaining a candidate delay count value based on the fifth count value and the sixth count value, and the largest candidate delay count value is used as the target delay count value, so that the device execution count value can be determined based on the target delay count value.

[0122] Please refer to Figure 7 In some embodiments, step S105 may include but is not limited to steps S701 to S702:

[0123] Step S701, obtaining the sum of the target sending count value, the target delay count value and the pre-designed value to obtain the expected execution count value;

[0124] Step S702, determining a device execution count value according to the expected execution count value; wherein the device execution count value is greater than or equal to the expected execution count value.

[0125] In step S701 to step S702 of this embodiment, the target transmission count value, the target delay count value and the pre-designed value are added to obtain the expected execution count value, and the device execution count value is greater than or equal to the expected execution count value, so that the master device and the slave device can simultaneously execute the target instruction when the count value of the system timer reaches the device execution count value.
