Example one
Fig. 1 is a schematic flowchart of a projector control method according to an embodiment of the present invention, where the method is applicable to controlling a projector device, and the method can be executed by a projector control apparatus configured on a server. As shown in fig. 1, the method specifically includes the following steps:
s110, receiving a projector control instruction sent by an application client; the projector control command comprises a control action, a control host ID and a projector device parameter.
The system comprises a target projector device, an application client, a server and at least one control host, wherein the user controls and operates the target projector device at the application client, the application client is connected with the server, the server is further connected with the at least one control host, and the control host is connected with the at least one projector device. And sending a projector control instruction to the server by the user at the application client, wherein the projector control instruction can comprise a control action, a control host ID, a projector equipment parameter and the like. The control action is a control operation of the target projector apparatus by the user, for example, turning on the projector or turning off the projector. The control host ID is the identity of the control host, which can be a computer or other like device. The projector device parameters are attribute information of the projector device, and a user can select a target projector device according to the projector device parameters.
In this embodiment of the present invention, optionally, before receiving the projector control instruction sent by the application client, the method further includes: generating a control host ID of a control host according to the application ID and the control host equipment identifier sent by the application client, feeding back the control host ID to the application client, and selecting the control host ID associated with target projector equipment when the application client sends a projector control instruction; and generating an information subject related to the control host ID according to the control host ID.
Specifically, the application client sends an application ID and a control host device identifier to the server, where the application ID is a coded identifier of an application controlling the projector, and the control host device identifier is a unique identifier of a control host connected to the projector device. And the server generates the ID of the control host according to the application ID and the equipment identifier of the control host, namely, the registration of the control host on the server platform is completed. After the control host registration is completed, the server allocates an information theme to each control host ID, and the information sent by all the application clients is forwarded to the control host by the corresponding information theme.
And after the server generates the control host ID, feeding the control host ID back to the application client, and when a user sends a control instruction, selecting a target control host according to the control host ID fed back by the server, wherein the target control host is a control host connected with the target projector equipment. For example, the server receives the application ID and the control host device identification, and calculates the control host ID to be 001. After detecting that the control host ID is generated, the server generates an information theme 0001 associated with the control host ID according to the control host ID, so that the control host is accessed into the server, subscribes the information theme associated with the control host, and receives information in the information theme. The application client receives the control host ID fed back by the server, can select the control host ID as 001 control host, and sends a control instruction to the server. The method has the advantages that the server can quickly find the corresponding information theme when transmitting the information to the control host through the incidence relation between the control host and the information theme, the instructions of different control hosts are prevented from being sent through the same information channel, and the information transmission efficiency is improved. And the ID of the control host is fed back to the application client, so that a user can quickly search the target control host, and the control efficiency of the projector is improved. The information interaction between the application client and the server may be performed through an MQTT (Message Queuing Telemetry Transport) protocol, and in this embodiment, the information interaction mode is not specifically limited.

The server acquires the control host ID in the control command of the control host, can encrypt the release information including the control action and store the release information in an information theme associated with the control host ID, the information theme sends the release information to the control host, and the control host decrypts the release information to obtain the control action on the control host. If the control action is a control host closing instruction, the control host sends the release information to the projector equipment associated with the control host before executing the control action on the control host, so that the projector equipment completes the control action in the release information. After the projector equipment finishes the control action in the release information, the control instruction acquires the state change information of the projector equipment, determines that the projector equipment finishes the action, and then executes the control action in the release information to the projector equipment. For example, the control host 001 is associated with two projector apparatuses a and B, a user issues a "close" instruction to the control host 001 at an application client, the server stores issue information of the "close" instruction in an information topic 0001 associated with the control host 001, the information topic 0001 sends the issue information to the control host 001, the control host 001 sends the issue information to a and B respectively, the a and B complete the closing operation of the projector apparatuses, and the control host 001 closes itself after determining that the a and B are closed. If the control action is a control host starting instruction, the control host firstly completes the self starting and then sends the starting instruction to the associated projector equipment, so that the projector equipment is automatically started. The control host and the projector equipment are controlled by the control host, so that the operation steps of a user are reduced, and the control efficiency of the projector is improved.
