Ensure the operating efficiency and reliability of the air conditioner.

Fig. 1 is a schematic flowchart of an air conditioner control method provided by an embodiment of the present disclosure. As shown in Figure 1, the process of air conditioning control includes:

Step 101: If the received current instruction is a control instruction, obtain the current identification code in the current instruction.

In the embodiment of the present disclosure, the air conditioner can receive instructions sent by the control terminal through wireless communication modules such as WIFI module, infrared module, Bluetooth module, or Zifeng module, wherein the control terminal can include: a server, a remote control, or a mobile terminal, etc. Wait, of course, it can also be some equipment that has monitored the communication data of the air conditioner. Therefore, as shown in FIG. 2 , the system for air conditioner control includes: an air conditioner 100 , and a control terminal 200 . Wherein, the air conditioner 100 can communicate through the control terminal 200 of wireless communication modules such as WIFI module, infrared module, bluetooth module, or Zifeng module.

The communication data between the air conditioner 100 and the control terminal 200 includes instructions sent by the control terminal 100, and the instructions received by the air conditioner can be divided into control instructions and non-control instructions, wherein the control instructions can include: start instructions, cooling instructions , dehumidification instructions, wind speed control instructions, etc., and non-control instructions may include: handshake instructions, synchronization instructions, etc.

When the received current command is a control command, the control command can be analyzed to obtain the current identification code in the current command. In some embodiments, the current identification code can be obtained directly from the control instruction. Or, in some embodiments, the control instruction is analyzed according to the set operation rules to obtain the current identification code in the current instruction.

In some embodiments of the present disclosure, if the received current instruction is a non-control instruction, generate and save the first identification code, and feed back a response instruction carrying the first identification code. It can be seen that when the air conditioner receives a non-control command, it can generate an identification code, here, the first identification code, and feed back a response command carrying the first identification code. Therefore, when the control terminal receiving the response command sends out the control command, it will carry the first identification code. However, other simulation-generated control commands may not carry an identification code, or the carried identification code is inconsistent with the identification code in the sent response command.

Step 102: When the current identification code is consistent with the identification code in the sent response command, control the operation of the air conditioner according to the current command.

In the embodiments of the present disclosure, the response instruction sent by the air conditioner before receiving the current instruction carries an identification code generated by the air conditioner. In some embodiments, the identification code is randomly generated by the air conditioner. Or, in some embodiments, the identification code is generated by setting an operation rule.

In this way, when the current command is received and the corresponding current identification code is obtained, the current identification code is matched and compared with the identification code in the sent response command. When the two are consistent, it can be confirmed that the current command is a legal control command. According to the current command, the operation of the air conditioner is controlled.

If the two are inconsistent, the current instruction may be an instruction simulated by the monitoring device, and the current instruction is not executed, that is, in some embodiments, when the current identification code is inconsistent with the identification code in the sent response instruction, the lock air conditioner.

It can be seen that in this embodiment, when the identification code in the received control command is consistent with the identification code in the sent response command, the air conditioner can execute the control command, which can effectively prevent the air conditioner from executing the control command sent by the monitoring device, reducing The possibility of unsafe operation of the air conditioner due to monitoring is reduced.

When the air conditioner receives a non-control command, it can generate a first identification code and carry the first identification code in the response command sent. For example, when the air conditioner receives a handshake command and confirms the handshake to reply, it can carry the first identification code in the response command. an identification code. Of course, in some embodiments, for the non-control commands simulated by the listening device, the air conditioner may not feed back the response commands.

In some embodiments, the current instruction received by the air conditioner is a control instruction, and after controlling the operation of the air conditioner according to the current instruction, the second identification code is also generated and saved, and a response instruction carrying the second identification is fed back. Certainly, the second identification code may be randomly generated by the air conditioner, or generated according to a set operation rule.

It can be seen that all the response commands sent by the air conditioner carry an identification code, which can be the first identification code or the second identification code, and the air conditioner only needs to generate the identification code, and the matching and comparison of the identification codes is simple and easy to implement. The air conditioner single-chip microcomputer with limited speed and storage capacity has no influence, ensuring the operating efficiency and reliability of the air conditioner.

Of course, if the communication data is lost, the identification code can be quickly generated through non-control commands to rebuild the communication.

In the following, the operation process is integrated into a specific embodiment to illustrate the air-conditioning control process provided by the embodiment of the present invention.

In this embodiment, the air conditioner can perform data communication through the wireless communication module.

Fig. 3 is a schematic flowchart of an air conditioner control method provided by an embodiment of the present disclosure. Combining with Figure 2 and Figure 3, the process for air conditioning control includes:

Step 301: The air conditioner receives the current instruction.

When the air conditioner receives the current instruction, it triggers the air conditioner control process in the embodiment of the present disclosure.

Step 302: Determine whether the current command is a control command? If yes, go to step 304; otherwise, go to step 303.

Step 303: Generate and save the first identification code, and feed back a response command carrying the first identification code, and return to step 301.

Every time the identification code is generated, the previously generated identification code is overwritten, that is, the first identification code generated at this time overwrites the previously generated identification code. And when the air conditioner determines to respond, the first identification code may be carried in the response instruction.

Step 304: Obtain the current identification code in the current instruction.

The current identification code may be zero characters, that is, there may be no identification code in the command simulated by the listening device.

Step 305: Determine whether the current identification code is consistent with the identification code in the sent response command? If yes, go to step 306; otherwise, go to step 308.

The identification code in the sent response instruction may be the first identification code or the second identification code.

Step 306: Control the operation of the air conditioner according to the current instruction.

Step 307: Generate and save the second identification code, and feed back a response command carrying the second identification. Return to step 301.

The generated second identification code overwrites the previously generated identification code. In this way, after each execution of the control command, the identification code can be randomly generated, which further ensures the legitimacy of the control command and further reduces the probability of unsafe operation of the air conditioner due to monitoring.

Step 308: discard the current command, and return to step 301.

If the current instruction may be an unqualified instruction, the current instruction is discarded, and the air conditioner can also be locked.

It can be seen that in this embodiment, when the identification code in the received control instruction is consistent with the identification code in the sent response instruction, the control instruction can be executed, thus effectively preventing the air conditioner from executing the control instruction sent by the monitoring device. The probability of unsafe operation of the air conditioner due to monitoring is reduced, and only the identification code is added, which has no effect on the air conditioner with limited execution speed and storage capacity, ensuring the operating efficiency and reliability of the air conditioner.

According to the above process for air-conditioning control, an apparatus for air-conditioning control can be constructed.

In some embodiments, it further includes: a locking module configured to lock the air conditioner when the current identification code is inconsistent with the identification code in the sent response instruction.

The following examples illustrate the device for air conditioner control provided by the embodiments of the present invention.

As shown in FIG. 5 , the air conditioner control device includes: an acquisition module 410 and a control module 420 , and may further include: a receiving module 430 , a first generation response module 440 , a second generation response module 450 and a locking module 460 .

Wherein, after the receiving module 430 receives the current instruction, if the current instruction is a non-control instruction, the first generation response module 440 randomly generates the first identification code and saves it, and feeds back the response instruction carrying the first identification code, and returns to the step 301. At this time, the generated first identification code overwrites the previously generated identification code. When the current instruction is a control instruction, the obtaining module 410 can obtain the current identification code in the current instruction, and when the current identification code is consistent with the identification code in the sent response instruction, the control module 420 can command to control the operation of the air conditioner.

Currently, after controlling the operation of the air conditioner, the second generating response module 450 can randomly generate a second identification code and save it, and feed back the response command carrying the second identification. At this time, the generated second identification code covers the previously generated identification code. code.

If the current identification code is inconsistent with the identification code in the sent response command, the locking module 460 may discard the current command and lock the air conditioner.

It can be seen that in this embodiment, the device for air conditioning control can execute the control command when the identification code received in the control command is consistent with the identification code in the sent response command, thus effectively preventing the air conditioner from executing The control command sent by the monitoring device reduces the chance of unsafe operation of the air conditioner due to monitoring, and the air conditioner only generates an identification code and performs matching judgment, which is simple and easy to implement, and has no effect on the air conditioner with limited execution speed and storage capacity , To ensure the operating efficiency and reliability of the air conditioner.
