In this embodiment, the step S30 includes:
s301: and allocating a first state identifier to the first client according to the first screen projection request.
When the first quantity does not reach the preset upper limit, the electronic device casts a screen to the first client, and specifically, a first state identifier is allocated to the first client to record the screen casting state of the first client.
S302: and creating a first screen projection display window according to the first state identifier.

For example, the second number is 3, the description layout information is to divide the screen space into three split screens, namely a left screen, an upper right screen and a lower right screen, the first client number is one, the screen projection client number is two, the screen projection client includes a first screen projection client and a second screen projection client, the original layout information of the screen projection client is to divide the screen space into two split screens, namely a left screen and a right screen, the screen projection display window corresponding to the first screen projection client occupies the left screen, and the screen projection display window corresponding to the second screen projection client occupies the right screen. At the moment, the right screen is divided into an upper right screen and a lower right screen, the time sequence number of the first screen projection client is obtained as one, the time sequence number of the second screen projection client is obtained as two, the time sequence number of the first client is obtained as three, the screen projection display window corresponding to the first screen projection client is projected to the left screen according to the time sequence number, the screen projection display window corresponding to the second screen projection client is projected to the upper right screen, and the first screen projection display window is projected to the lower right screen.

step S401: monitoring whether a screen projection finishing request sent by a second client side is received, wherein the second client side is in a screen projection state, and a second state identifier of the second client side is stored in the equipment state list;
step S402: stopping screen projection on the second client when the screen projection ending request is monitored;
step S403: and reading a second screen projection request from the waiting queue, and projecting a screen of the client corresponding to the second screen projection request.
The second client is a screen projection client which wants to finish screen projection, in order to process the screen projection requests in the waiting queue, the electronic equipment monitors whether the screen projection finishing request sent by the second client is received or not, and stops screen projection on the second client when the screen projection finishing request is monitored, and then the current screen projection number of the electronic equipment is less than the maximum screen projection number, so that the screen projection requests in the waiting queue can be processed. Therefore, the electronic device reads a second screen projection request from the waiting queue and projects a screen of the client corresponding to the second screen projection request.
Further, before the step S403, the method further includes: acquiring each screen projection request to be processed in the waiting queue and authentication information corresponding to each screen projection request to be processed, wherein the waiting queue comprises a plurality of screen projection requests to be processed, and the authentication information comprises sending time and/or client identity information; calculating the priority of each screen projection request to be processed according to the authentication information; and sequencing the plurality of screen casting requests to be processed according to the sequence of the priority from high to low, and taking the screen casting request to be processed with the highest priority as the second screen casting request.
And when the number of screen throwing requests to be processed in the waiting queue is larger than the number of screen throwing requests, calculating the priority of each screen throwing request to be processed according to the authentication information of each screen throwing request to be processed, and selecting the screen throwing request to be processed with the highest priority from the waiting queue as a second screen throwing request to respond. The authentication information comprises sending time and/or client identity information, specifically, the priority of each screen throwing request to be processed is calculated according to the sending time of each screen throwing request to be processed, the priority of the screen throwing request to be processed before the sending time is higher than the priority of the screen throwing request to be processed after the sending time, and therefore the screen throwing request to be processed before the sending time can be responded preferentially. Or calculating the priority of each screen projection request to be processed according to client identity information corresponding to each screen projection request to be processed, wherein the client identity information is information for distinguishing client identities, for example, in a teaching scene, the importance degree of a teacher client is higher than that of a student client, so that the priority of the teacher client is higher than that of the student client, and the screen projection requests to be processed with higher importance degree can be responded preferentially. Or the priority of each screen throwing request to be processed is calculated according to the sending time of each screen throwing request to be processed and the client identity information, and the screen throwing requests to be processed with the sending time before and higher in importance degree can be preferentially responded by combining the sending time and the client identity information.
Further, the step S402 includes:
when the screen projection ending request is monitored, destroying a second screen projection display window corresponding to the second client;
and deleting the second state identification from the device state list.
When the screen projection ending request is monitored, screen projection is ended by destroying a second screen projection display window corresponding to the second client, the second state identification of the second client is updated to be in the third state in the equipment state list, and when the second state identification of the second client is updated to be in the third state, the second state identification is deleted from the equipment state list, so that the state identification in the equipment state list is reduced, and the screen projection request to be processed in the waiting queue can be processed.
Further, after the step S40, the method further includes:
if the first number reaches the preset upper limit, judging whether the current system idle rate reaches a preset idle rate; if the current system idle rate reaches the preset idle rate, adding a preset value to the preset upper limit to obtain a new preset upper limit, and returning to the step S20.
When the idle rate of the current system is high, the upper limit value is increased moderately, and the screen projection quantity can be increased on the premise of ensuring the fluency of the screen projection system.
The technical scheme provided in the embodiment of the application at least has the following technical effects or advantages:
in the embodiment, whether a screen projection ending request sent by the second client is received or not is monitored; stopping screen projection on the second client when the screen projection ending request is monitored; and reading a second screen projection request from the waiting queue, and projecting a screen to the client corresponding to the second screen projection request, so that the processing efficiency of the screen projection request in the waiting queue is improved.
