Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of an internet of things provided by an embodiment of the present disclosure. As shown in fig. 1, the internet of things may include: fig. 1 illustrates an example in which the internet of things includes three internet of things devices 20.
The sending device 10 of the control instruction and each internet of things device 20 can establish connection through a wired network or a wireless network.
The sending device 10 of the control instruction is a device that can generate the control instruction and directly send the generated control instruction to the internet of things device 20. The sending device 10 of the control instruction may be a server, a server cluster composed of a plurality of servers, or a cloud computing service center.
Alternatively, a control application may be installed in the sending device 10 of the control instruction, and the sending device 10 may generate the control instruction in response to an operation for the control application.
The internet-of-things device 20 is a device that performs an operation indicated by the control instruction sent by the sending device 10, and may be, for example, an air conditioner, an electric lamp, an engine, a fan, or the like.
Fig. 2 is a schematic diagram of another internet of things provided by the embodiment of the disclosure. As shown in fig. 2, the internet of things may include a transmitting device 10 of a control instruction, a plurality of internet of things devices 20, and a control device 30. Fig. 2 illustrates the internet of things including three internet of things devices 20.
The sending device 10 of the control instruction and each internet of things device 20, and the sending device 10 and the control device 30 may establish connection through a wired network or a wireless network.
The control device 30 is a device that can generate a control instruction and transmit the generated control instruction to the transmission device 10 of the control instruction. The control device 30 may be a server, a server cluster composed of a plurality of servers, or a cloud computing service center. Alternatively, a control application may be installed in the control device 30, and the control device 30 may generate a control instruction in response to an operation for the control application.
The sending device 10 of the control instruction is a device that sends the control instruction sent by the control device 20 to the internet of things device 20, and therefore the sending device 10 of the control instruction may also be referred to as a proxy device or a gateway device.
Fig. 3 is a flowchart of an instruction sending method according to an embodiment of the present disclosure. The method can be applied to the sending device 10 of the control instruction in the internet of things shown in fig. 1 or fig. 2. As shown in fig. 3, the method may include:
After the sending device sends at least one control instruction to the internet of things device in the first time period, a sending result of the at least one first control instruction can be obtained. Wherein, the sending result of each first control instruction may include: the transmission is successful or failed, and for a scenario in which the transmission is successful, the transmission result may further include a transmission delay of the first control instruction. The transmission delay refers to a transmission duration of the first control instruction, that is, a duration from the sending device sending the first control instruction to the internet of things device receiving the first control instruction.
After obtaining the sending result of the at least one first control instruction, the sending device may stop sending the first control instruction that fails to be sent to the internet of things device if it is determined that the communication link between the sending device and the internet of things device is congested based on the sending result. If it is determined that the communication link between the sending device and the internet of things device is not congested based on the sending result, the instruction sending process according to the embodiment of the application may be ended, and the control instruction may be sent according to a conventional instruction sending manner.
After obtaining a plurality of second control instructions to be sent in a second time period, the sending device may determine at least one target control instruction based on the plurality of second control instructions, where the second time period is after the first time period, and the number of the at least one target control instruction is smaller than the number of the plurality of second control instructions. Optionally, the duration of the second period may be less than or equal to the duration of the first period. For example, the duration of the second period may be 10 seconds(s), and the duration of the first period may be 60 s.
And step 304, sending at least one target control instruction to the Internet of things equipment.
After determining the at least one target control instruction, the sending device may send the at least one target control instruction to the internet of things device, so that the internet of things device may perform an operation indicated by the at least one target control instruction. Optionally, the sending device may send the at least one target control instruction sequentially, or may send the at least one target control instruction simultaneously.
In summary, the embodiment of the present disclosure provides an instruction sending method, where if a sending device determines that a communication link between the sending device and an internet of things device is congested based on a sending result of at least one first control instruction sent to the internet of things device in a first time period, the sending device may stop sending a first control instruction that fails to be sent in the at least one first control instruction. The first control instruction which fails to be sent does not need to be sent repeatedly, so that the sending equipment can send the control instruction to be sent in a second time period after the first time period in time, and the efficiency of sending the control instruction to be sent in the second time period to the Internet of things equipment is effectively improved.
And the sending device may determine at least one target control instruction from a plurality of second control instructions to be sent in a second time period, and send the at least one target control instruction to the internet of things device. Because the number of the at least one target control instruction is smaller than the number of the plurality of second control instructions, the number of the control instructions sent to the internet of things equipment in the second time period is effectively reduced, and the efficiency of sending the control instructions to the internet of things is further improved.
Fig. 4 is a flowchart of another instruction sending method provided in an embodiment of the present disclosure. The method can be applied to the internet of things shown in fig. 1 or fig. 2. As shown in fig. 4, the method may include:
step 401, a sending device obtains a sending result of at least one first control instruction sent to an internet of things device in a first time period.
In the embodiment of the disclosure, after the sending device sends at least one control instruction to the internet of things device in the first time period, a sending result of the at least one first control instruction may be obtained. Wherein, the sending result of each first control instruction may include: the transmission is successful or failed, and for a scenario in which the transmission is successful, the transmission result may further include a transmission delay of the first control instruction. The transmission delay refers to a transmission duration of the first control instruction, that is, a duration from the sending device sending the first control instruction to the internet of things device receiving the first control instruction.
Step 402, if the sending device determines that a communication link between the sending device and the internet of things device is congested based on the sending result, the sending device stops sending the first control instruction with failure in the at least one first control instruction.
After obtaining the transmission result of the at least one first control instruction, the transmitting device may determine whether a communication link between the transmitting device and the internet of things device is transmitting congestion based on the transmission result. If it is determined that a communication link between the sending device and the internet of things device is congested, sending of the first control instruction with the failure in the at least one first control instruction may be stopped. The first control instruction which fails to be sent does not need to be sent repeatedly, so that the sending equipment can send the control instruction to be sent in a second time period after the first time period in time, and the efficiency of sending the control instruction to be sent in the second time period to the Internet of things equipment is effectively improved. The duration of the second time period may be less than or equal to the duration of the first time period, for example, the duration of the second time period is 10s, and the duration of the first time period is 60 s.
In an optional implementation manner of the embodiment of the present disclosure, after obtaining a sending result of at least one first control instruction, the sending device may determine a number ratio of first control instructions that have failed to be sent in the at least one first control instruction. If it is determined that the number proportion is greater than or equal to the first proportion threshold, the sending device may determine that a communication link between the sending device and the internet of things device is congested. If it is determined that the number ratio is smaller than the first ratio threshold, the sending device may determine that the communication link between the sending device and the internet of things device is not congested. Wherein, the first proportional threshold is a fixed value pre-stored in the sending device.
For example, assuming that the first proportional threshold is 0.3, the number of first control commands transmitted by the transmitting device in the first period is 30, and the number of failed first control commands in the 30 first control commands is 15, the transmitting device may determine that the ratio of the number of failed first control commands in the 30 first control commands is 0.5. Since 0.5>0.3, the sending device may determine that a communication link between the sending device and the internet of things device is congested.
In another optional implementation manner of the embodiment of the present disclosure, the sending device may determine a number ratio of the first control commands, of which the transmission delay is greater than or equal to the delay threshold, in the at least one first control command. If it is determined that the number proportion is greater than or equal to the second proportion threshold, it may be determined that a communication link between the sending device and the internet of things device is congested. If it is determined that the number ratio is smaller than the second ratio threshold, it may be determined that the communication link between the sending device and the internet of things device is not congested. The delay threshold and the second proportional threshold are both fixed values pre-stored in the sending device.
For example, assuming that the delay threshold is 5s, the second proportional threshold is 0.4, and the transmission delay of 15 first control commands among the 30 first control commands is greater than or equal to the delay threshold, the sending device may determine that the ratio of the first control commands among the 30 first control commands whose transmission delay is greater than or equal to the delay threshold is 0.5. Since 0.5>0.4, the sending device may determine that a communication link between the sending device and the internet of things device is congested.
In another optional implementation manner of the embodiment of the present disclosure, if it is determined that the ratio of the number of the first control instructions that are failed to be sent in the at least one first control instruction is greater than or equal to a first ratio threshold, and the ratio of the number of the first control instructions with the transmission delay greater than or equal to a delay threshold in the at least one first control instruction is greater than or equal to a second ratio threshold, the sending device may determine that a communication link between the sending device and the internet of things device is congested. If it is determined that the number ratio of the first control instructions which fail to be sent in the at least one first control instruction is smaller than a first ratio threshold, or the number ratio of the first control instructions of which the transmission delay is greater than or equal to the delay threshold in the at least one first control instruction is smaller than a second ratio threshold, the sending device may determine that the communication link between the sending device and the internet of things device is not congested.
It is to be understood that the first proportional threshold and the second proportional threshold may be equal or different, and the embodiment of the disclosure is not limited thereto.
Step 403, the sending device determines at least one target control instruction based on a plurality of second control instructions to be sent in the second time period.
After determining that a communication link between the sending device and the internet of things device is congested, for a plurality of second control instructions to be sent in a second time period, the sending device may determine at least one target control instruction based on the plurality of second control instructions. The number of the at least one target control instruction is smaller than the number of the plurality of second control instructions.
Because the number of the at least one target control instruction is smaller than the number of the plurality of second control instructions, the number of the control instructions which need to be sent to the internet of things equipment in the second time period is effectively reduced, the occupation of the memory in the sending equipment is effectively reduced, and the efficiency of sending the control instructions to the internet of things is further improved.
The following describes a process of determining, by the transmitting device, at least one target control instruction based on a plurality of second control instructions to be transmitted in the second time period:
in the embodiment of the present disclosure, the first control type, the second control type, and the third control type are stored in advance in the transmission device. If the sending device determines that a plurality of first candidate instructions belonging to the first control type exist in the plurality of second control instructions, the sending device may determine a target control instruction with the latest instruction obtaining time from the plurality of first candidate instructions. The first control type control instruction comprises a first control value of a controlled parameter, and the first control instruction is used for indicating that a parameter value of the controlled parameter is adjusted to the first control value. That is, the control instruction of the first control type refers to an instruction for adjusting a parameter value of a controlled parameter of the internet of things device to a specified value.
It is understood that, for a scenario in which the control instruction is generated by the transmitting device, the acquisition time of the control instruction may refer to the time at which the transmitting device generates the control instruction, i.e., the acquisition time of the control instruction refers to the generation time of the control instruction. For a scenario in which the control instruction is generated by the control device and sent to the sending device, that is, a scenario in which the sending device is a proxy device or a gateway device, the obtaining time of the control instruction may be a time at which the sending device receives the control instruction sent by the control device, that is, the obtaining time of the control instruction is a receiving time of the control instruction.
The control instruction of the first control type is an instruction for adjusting the parameter value of the controlled parameter of the internet of things device to a specified value, so that the target control instruction with the latest time is obtained from the multiple first candidate instructions and the parameter value of the controlled parameter of the internet of things device can be directly adjusted by the first control value in the target control instruction. Therefore, the number of the control instructions sent to the Internet of things equipment is reduced while the control effect on the Internet of things equipment is not influenced, and the efficiency of sending the control instructions to the Internet of things equipment is improved.
For example, if the first control type is to adjust the air-conditioning temperature, that is, the controlled parameter is the air-conditioning temperature, the plurality of first candidate commands are used to instruct to adjust the parameter value of the air-conditioning temperature to 25 ℃, the parameter value of the air-conditioning temperature to 26 ℃, the parameter value of the air-conditioning temperature to 27 ℃ and the parameter value of the air-conditioning temperature to 28 ℃, respectively. That is, the first control values in the plurality of first candidate instructions are 25 ℃, 26 ℃, 27 ℃ and 28 ℃, respectively. If the five first candidate instructions, the candidate instruction: adjusting the parameter value of the air conditioner temperature to be at the latest acquisition time of 28 ℃, the sending device may determine a target control command as: the parameter value of the air conditioning temperature was adjusted to 28 ℃.
Optionally, if it is determined that a plurality of second candidate instructions belonging to the second control type exist in the plurality of second control instructions, the sending device determines at least one target control instruction from the plurality of second candidate instructions.
The control instruction of the second control type is used for indicating and adjusting the working state of the internet of things device, and the working state may include an on state, an off state, a standby state, an energy saving state, or the like. The plurality of second alternative instructions may include at least one alternative instruction group, each alternative instruction group may include one second alternative instruction, or a plurality of second alternative instructions having consecutive instruction acquisition times and the same instruction content. Each target control instruction is a second alternative instruction in an alternative instruction group, namely the number of the at least one target control instruction is the same as that of the at least one alternative instruction group.
The control instructions of the second control type are used for indicating and adjusting the working state of the Internet of things equipment, and only one second alternative instruction which is continuous at any time and has the same instruction content is sent to the Internet of things equipment, so that the number of the control instructions sent to the Internet of things equipment is reduced while the control effect on the Internet of things equipment is not influenced, and the efficiency of sending the control instructions to the Internet of things equipment is improved.
For example, if the second control type is to adjust the operating state (i.e., the switching state) of the electric lamp, the plurality of second candidate commands includes three candidate command groups, the first candidate command group includes two second candidate commands, the two second candidate commands are obtained at consecutive times, and the contents are: and adjusting the working state of the electric lamp to be in an off state. The second alternative instruction group comprises two second alternative instructions, the acquisition time of the two second alternative instructions is continuous, and the contents are as follows: and adjusting the working state of the electric lamp to be in an opening state. The third alternative instruction set includes a second alternative instruction: and adjusting the working state of the electric lamp to be in an off state. The sending device may determine one target control instruction from each of the candidate instruction groups to obtain three target control instructions. The three target control instructions are respectively a second alternative instruction in the first alternative instruction group: adjusting the working state of the electric lamp to be in an off state, and adjusting a second alternative instruction in a second alternative instruction group: adjusting the working state of the electric lamp to be in an on state, and adjusting a second alternative instruction in a third alternative instruction group: and adjusting the working state of the electric lamp to be in an off state.
Optionally, if any candidate instruction group includes a plurality of second candidate instructions, the target control instruction determined from the candidate instruction group may be the second candidate instruction with the earliest instruction execution time in the candidate instruction group. Each second candidate instruction may carry an execution time of the second candidate instruction, where the execution time of the instruction refers to a time when the internet of things device executes the instruction.
In the process of generating a control command by a control device or a proxy device, a plurality of control commands with the same content and continuous generation time but different execution time may be generated due to human misoperation. By sending the second alternative instruction with the earliest execution time to the Internet of things equipment, accurate control over the Internet of things equipment can be effectively ensured.
For example, if the second control type is to adjust the operating state (i.e., the on-off state) of the sprinkler, the plurality of second candidate commands includes three candidate command groups, the first candidate command group includes two second candidate commands with consecutive acquisition times, the two second candidate commands both have the content of adjusting the operating state of the sprinkler to the off state, and the execution times carried by the two second candidate commands are 10 o 'clock 10 min and 10 o' clock 11 min, respectively.
