Description
Technical Field
The invention relates to a method for turning on and turning off a projector, in particular to a method for simultaneously turning on and turning off a plurality of projectors, belonging to the technical field of projector application.
Background
The projector generally has several methods for turning on and off the projector, namely, turning on and off the projector through a key on the projector body, remotely turning on and off the projector, turning on and off the projector through an r232 port and turning on and off the projector through an rj45 port. If a plurality of projectors are used simultaneously in the same application scene (usually, a plurality of projectors are spliced and fused), the following problems are encountered during shutdown, and if the projectors are turned on and off through keys on a machine body, the operation is inconvenient, because the machines are installed at a high place in most cases. When the machine is turned on or off by remote control, because the remote control is not available or the machine is disordered due to the installation angle, when another machine is turned off, the machine which is already turned off is turned on again after receiving the latest on/off key. Therefore, the projection on-off control cannot be realized by the above two methods in the general splicing and fusion process. When the machine is started and shut down through the rj45, the rj45 startup and shut down method of most machines is not suitable for splicing and fusing because the current method is that the computer is connected with a projection through a network cable and then enters a projection internal control webpage to control the machine. So most splicing fusion is controlled by r232 port.
One of the conventional architectures is a control architecture in which a console is connected to a serial port distributor through an r232 port, and then a path of light is output from the distributor to each projector. In the structure, with the increase of the number of projection machines, the number of distributors is correspondingly increased, and the number of lines is increased, so that the distribution is relatively disordered. In another architecture, a method of r232 serial port loop connection is adopted, the output end of the r232 port of one machine is connected with the input end of the r232 port of another machine, so that a serial port distributor is not needed, the wire is relatively short, and the architecture is more in use because the serial port distributor is not needed. The two r232 control methods have a common disadvantage that on-off control commands of each projector must be the same, and the r232 serial port baud rate must also be the same, the first r232 architecture has a serial port distributor, so the cost is increased, the serial port connecting lines are more and long, and the wiring is difficult, the second architecture requires the on-off control commands of the projector to be the same, and the serial port baud rates must also be the same, so that machines of different manufacturers often have respective on-off commands and baud rates. Therefore, a method for simultaneously turning on and off a plurality of projectors is provided to solve the above problems.

b, when the machines connected in the step A are machines of the same type, the multiple machines can be turned on and off by using default on-off commands in the machines;
step C, when the machines connected in the step A are machines of different models, inputting a specific command by a computer through an r232 input port of the projector, and at the moment, enabling the projector to enter a specific state;
d, in the state of the step C, the projector receives the data received by the r232 port and is used for modifying own on-off commands, commands output from the r232 port during on-off and baud rates input and output by a serial port of the projector;
and step F, storing the command modified in the step D into a memory in the machine, and modifying the on-off command and the baud rate of the machine and the on-off command and the baud rate output by the r232 port, so that the compatibility problem of the on-off command and the baud rate of machines of different models is solved.
Preferably, the specific command input in step C may be the same as or different from the command received by the r232 port of the projector, and the specific command is a command for controlling the on/off of the projector.
