Embodiment 1

[0016] A method for turning on and off multiple projectors at the same time, comprising the following steps:

[0017] Step A. When the machine receives the switch command, it also outputs a specific command from its own r232 output port. This command is used to control the machine connected to its r232 output port;

[0018] Step B, when the connected machines in step A are machines of the same model, using the default on / off command inside the machine can realize the on / off of multiple machines;

[0019] Step C, when the connected machines in step A are machines of different models, use a computer to input a specific command through the r232 input port of the projector, and at this time, the projector enters a specific state;

[0020] Step D. In the state of step C, the projector receives the data received by the r232 port to modify its own power-on / off command, the command output from the r232 port when the projector is on / off, and the baud rate of the machine’s serial port i...

Embodiment 2

[0024] When the output and input ports of the R232 are combined into one port, in this case, a specific transfer line must be added externally to use it. It is a method for turning on and off multiple projectors at the same time, including the following steps:

[0025] Step A. When the machine receives the switch command, it also outputs a specific command from its own r232 output port. This command is used to control the machine connected to its r232 output port;

[0026] Step B, when the connected machines in step A are machines of the same model, using the default on / off command inside the machine can realize the on / off of multiple machines;

[0027] Step C, when the connected machines in step A are machines of different models, use a computer to input a specific command through the r232 input port of the projector, and at this time, the projector enters a specific state;

[0028] Step D. In the state of step C, the projector receives the data received by the r232 port to m...

Abstract

The invention discloses a method for simultaneously powering on / off multiple projectors. The method comprises the following steps: when a machine receives a powering on / off instruction, outputting a specific instruction from an r232 output port of the machine self; when a machine connected with the machine is of a same model, powering on / off multiple machines by using a default powering on / off instruction of the machines; when the machine connected with the machine is of a different model, inputting a specific instruction through an r232 input port of a projector by a computer, wherein the projector is at a specific state at the moment; receiving data received by the r232 port by the projector, modifying a powering on / off instruction of the projector self, an instruction output from the r232 port when the projector is powered on / off, and input / output Baud rates of machine serial ports; storing modified instructions into memories inside the machines. By modifying the powering on / off instructions and Baud rates of machines selves, and powering on / off instructions and Baud rates output from r232 ports, the problem of compatibility of powering on / off instructions and Baud rates of machines of different models is solved.

Description

technical field [0001] The invention relates to a method for turning on and off a projector, in particular to a method for turning on and off a plurality of projectors at the same time, and belongs to the technical field of projector applications. Background technique [0002] Now the projector generally has the following several ways to switch the machine on and off, the button switch on the fuselage, the remote control switch machine, the switch machine through the r232 port and the switch machine through the rj45 port. In the same application scenario, if you use multiple projectors at the same time (commonly, multiple projectors are spliced ​​and fused) and shut down, you will encounter the following problems. It is a bit inconvenient to switch the projector through the buttons on the fuselage. Because the machine is installed at a high place in most cases. If you use the remote control to turn on and off the machine, sometimes the remote control cannot be controlled du...
