FIG. 1 is a system diagram of the air conditioner Internet of Things system of the present invention.

Detailed ways

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention.

Based on the problem that the existing air conditioners cannot achieve systematic management and control pointed out in the background art, the present invention provides an air conditioner Internet of Things system, which aims to realize the management and control of air conditioner terminals in all areas and improve user experience by establishing an air conditioner Internet of Things system.

Specifically, as shown in FIG. 1 , the air conditioner Internet of Things system of the present invention includes a cloud server, a development terminal and a plurality of air conditioner terminals. The development terminal and the plurality of air conditioner terminals communicate with the cloud server, and each air conditioner terminal is set to be able to Its own geographic location information, fault information and system information are uploaded to the cloud server. The cloud server is set to be able to send the collected fault information of all air-conditioning terminals to the development terminal. The location information and system information deliver corresponding update programs, and each air conditioner terminal is set to be able to selectively update its own program according to the update program downloaded from the cloud server. It should be noted that the communication methods between the development terminal and multiple air-conditioning terminals and the cloud server include but are not limited to wireless communication methods such as 3G, 4G, 5G, and wifi. A cloud server can be a development cloud platform for any integrated system, usually integrating distributed computing environments, big data and cloud computing support, and industrial mobile monitoring and control functions. The development terminal may be a development program terminal running in the developer device, wherein the human-computer interaction interface of the development program terminal may be realized based on a self-developed software program, and in other examples, it may also be realized by means of web or the like. The air-conditioning terminal can be a multi-connected air-conditioning system, an ordinary household air conditioner, or other chiller units or heat pump units. The geographic location information may include regional information (such as tropical regions, temperate regions, coastal regions, inland regions, and desert regions, etc.), as well as longitude and latitude information, etc. The system information may include product information and operation information of the air conditioner terminal itself.

Preferably, the fault information includes a fault type and a fault occurrence rate. In the case that the fault occurrence rate in the set area is greater than a preset value, the cloud server generates a fault report and sends it to the development terminal. The fault occurrence rate can be statistically calculated by taking all fault types as a set, and can also be statistically calculated by using similar fault types as a set, and can also be statistically calculated by taking exactly the same fault types as a set. When the failure occurrence rate is statistically calculated by using similar failure types or identical failure types as a set, if the failure occurrence rate of this type of failure type is greater than the preset value, it means that the failure needs to be solved urgently, and developers can prioritize it .

As an improvement to the above-mentioned embodiment, the fault occurrence rate of each type of fault can also be counted and compared in turn, and the various types of faults can be sorted according to their fault occurrence rates, and the cloud server will report these faults in the fault report. For developers, developers can determine the priority of processing according to the level of failure rate, and solve key problems for users first.

Further, after the developer has dealt with the fault, it can be integrated into the update program and uploaded to the cloud server, and the cloud server will automatically deliver it to the corresponding air-conditioning terminal for unified program update. Of course, you can only upload the program containing the fault solution to the cloud server for storage. When the cloud server receives the fault information of the same fault type uploaded by one or some air conditioner terminals, the cloud server directly retrieves the fault solution containing the fault solution. The program of the corresponding air conditioner is sent to the corresponding air conditioner terminal for program update, and the fault report of this fault type is no longer generated and fed back to the development terminal, so as to avoid repeated feedback from the development terminal.

Preferably, in the case where no fault occurs in the air conditioner terminal, the cloud server sends a detection instruction to the air conditioner terminal, the air conditioner terminal uploads detection information to the cloud server after the detection is completed, and the cloud server judges the air conditioner based on the detection information uploaded by the air conditioner terminal. Whether the air conditioner terminal is faulty. If there is no fault in an air-conditioning terminal all the time or within a set period of time, the cloud server will actively send a detection command to the air-conditioning terminal. If the feedback from the air-conditioning terminal can be obtained, it proves that it is not a signal transmission problem. , if no feedback from the air-conditioning terminal is obtained, it proves that there is a problem in the communication between the air-conditioning terminal and the cloud server, and maintenance personnel need to be notified in time for maintenance. In addition, the air-conditioning terminal can upload the detection information to the cloud server after receiving the detection instruction from the cloud server and after the detection, and the cloud server can judge whether the air-conditioning terminal is faulty according to the detection information. All air-conditioning terminals in the area can be controlled. In practical applications, each air-conditioning terminal can be implanted or written into a product identification program before leaving the factory, so that the cloud server can monitor it after leaving the factory, so that no matter where the air-conditioning terminal is eventually used in the world, the cloud Servers can be managed and controlled according to their geographic location and program updates can be performed in a targeted manner. If the air conditioner terminal is an ordinary household air conditioner, etc., it is not running all the time, but only when the user chooses to use it. Therefore, the household air conditioner can feedback the startup status to the cloud server every time it is turned on, which can ensure that the cloud server can The detection instruction is issued within the time period when the air conditioner is turned on and running.

In a preferred situation, continuing to refer to FIG. 1 , the air conditioner Internet of Things system of the present invention further includes an after-sales terminal, and the cloud server sends a detection instruction to an air conditioner terminal that has not failed but does not receive the detection information uploaded by the air conditioner terminal. In this case, the cloud server sends the maintenance task of the air conditioner terminal to the after-sales terminal. That is, the cloud server sends maintenance tasks to the maintenance personnel through the after-sales terminal, so that the maintenance personnel can quickly contact the user for maintenance. In another preferred situation, the air conditioner Internet of Things system of the present invention further includes an after-sale terminal, and when the air-conditioning terminal does not have any fault, the cloud server sends the air-conditioning terminal maintenance task to the after-sale terminal. That is, as long as there is no fault in the air-conditioning terminal, the cloud server will send the maintenance task of the air-conditioning terminal to the after-sales terminal, so that after-sales personnel can actively return to the user and provide relevant maintenance services, check whether the air-conditioning is faulty on site, and improve the user experience.

Preferably, when the air-conditioning terminal receives the update program issued by the cloud server, the air-conditioning terminal sends a confirmation request to the user whether to update, and if the air-conditioning terminal receives the confirmation instruction input by the user, the air-conditioning terminal will make the air-conditioning terminal update its own program. renew. That is, when the air conditioner terminal receives the update program sent by the cloud server, it will ask the user whether to perform the update. If the user chooses to update, the update will be performed. If the user does not choose to update, the update program can be stored locally, and subsequent users Select update and then update. If the user has not selected update, and the cloud server has issued another new update program, the original update program can be deleted, and then the user can choose whether to update based on the newly issued update program. In the above, if the user chooses to update, the air conditioner terminal can back up the original program, and if the user regrets after the update is completed, the program can be restored.

Preferably, when the air conditioner terminal receives the update program issued by the cloud server, the air conditioner terminal sends a confirmation request for update to the user, and if the air conditioner terminal does not receive the confirmation instruction input by the user within the set time, the air conditioner The terminal automatically updates its own programs. That is, when the air conditioner terminal receives the update program sent by the cloud server, it will ask the user whether to perform the update. If the user does not choose to update, the update program can be stored locally, and then the controller of the air conditioner terminal starts timing. When the time is set (for example, 24 hours), if the user has not selected the update, the air conditioner terminal will be forced to update, so as to avoid affecting the update due to the user's failure to confirm in time, resulting in frequent failures or non-optimal operation of the air conditioner terminal. . Of course, in the above, if the air conditioner terminal is finally updated, the air conditioner terminal can back up the original program, and if the user regrets it after the update is completed, the program can be restored.

Preferably, when the air conditioner terminal receives the update program issued by the cloud server, the air conditioner terminal sends a confirmation request for update to the user, if the air conditioner terminal does not receive the confirmation instruction input by the user within the first set time, then The air conditioner terminal sends a confirmation request for updating to the user again, and if the air conditioner terminal does not receive the confirmation instruction input by the user within the second set time, the air conditioner terminal automatically updates its own program. That is, when the air conditioner terminal receives the update program sent by the cloud server, it will ask the user whether to update. If the user does not choose to update, the update program can be stored locally, and then the controller of the air conditioner terminal will start timing. At the first set time, if the user has not selected the update, the air conditioner terminal will ask the user whether to update again. If the user has not yet selected the update, the controller of the air conditioner terminal restarts the timing. When the timing reaches the second set time, If the user has not chosen to update, the air conditioner terminal is forced to update, so as to avoid affecting the update due to the user's failure to confirm in time, resulting in frequent operating failures of the air conditioner terminal or often in a non-optimal operating state. Wherein, the second set time can be equal to the first set time, of course, it is preferable that the second set time is less than the first set time (for example, the first set time is 24 hours, and the second set time is 12 hours) , that is, the time limit for determining the update provided to the user for the second time is shorter to ensure the timeliness of the update. Of course, in the above, if the air conditioner terminal is finally updated, the air conditioner terminal can back up the original program, and if the user regrets it after the update is completed, the program can be restored.

Further, in the case that the air conditioner terminal completes the update of its own program, the air conditioner terminal sends a prompt message that the update is successful to the user. The prompt can be displayed on the display interface of the air conditioner panel, or displayed on the display interface of the air conditioner remote control, or the air conditioner communicates with a mobile terminal (such as a mobile phone, tablet computer, etc.), and then the air conditioner sends a message to the mobile terminal. Push information to inform users.

In the above, the cloud server can send the update program to the air-conditioning terminal in the form of subcontracting, and the air-conditioning terminal can perform centralized verification on each data packet, that is, when the cloud server sends all the data packets to the air-conditioning terminal, the air-conditioning terminal can perform Verification, in other cases, the air conditioner terminal can verify the data packets one by one, that is, the air conditioner terminal will immediately verify every time the cloud server sends a data packet to the air conditioner terminal, and the cloud server will be allowed after the current packet verification is successful. Continue to deliver the next data package. If the verification fails, the air conditioner terminal will re-download the failed data package. If it fails again, it will re-download all the data packages. If it still fails, the update will be rejected and the upload will fail. report to the cloud server. The verification process may include content verification and error code judgment, etc., and the content verification may adopt plaintext verification and the like.

Preferably, the air-conditioning IoT system of the present invention also communicates with non-air-conditioning equipment, and the air-conditioning IoT system is further configured to be able to share the information of all air-conditioning terminals and all non-air-conditioning devices in the same target area.
