Embodiment Construction

[0028] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0029] figure 1 It is a flowchart of a method for sending a control instruction according to an embodiment of the present invention. Such as figure 1 As shown, the sending method of the control command includes:

[0030] Step S101: Construct a control instruction containing a control instruction address, where the control instruction address includes: an instruction group address for indicating the device group to which the controlled device belongs and an instruction mask for indicating the unit address of the controlled device;

[0031] Step S103: Send the constructed control instruction through a wired channel or a wireless channel.

[0032] in figure 1 In the method shown, all controlled devices are divided into several groups, and the control command includes two parts: the command group address and the command mask repre...

Abstract

The invention provides a sending and responding method and device of a control instruction. The sending method comprises the steps that the control instruction containing a control instruction address is built, wherein the control instruction address comprises an instruction set address and an instruction mask used for indicating a unit address of controlled equipment, and the instruction set address is used for indicating an equipment set comprising the controlled equipment; the built control instruction is sent through a wire channel or a wireless channel, and the controlled equipment responds to the control instruction according to the method. According to the technical scheme, the data volume of equipment address information sent while the equipment is controlled is greatly reduced. In addition, the equipment addressing and controlling method has high flexibility, and each piece of equipment can be independently controlled.

Description

Technical field [0001] The present invention relates to the field of control, and in particular to a method and device for sending and responding to control instructions. Background technique [0002] During the use of industrial equipment, alarm equipment, entertainment equipment and other equipment, it is sometimes necessary to efficiently control part of all equipment. For example, in the traffic information bulletin system, the specified information content needs to be displayed in some traffic information display screens, while the content of other traffic information display screens remains unchanged; in the process of sending alarm signals from the alarm system, part of all alarm equipment needs to be displayed Switch to the alarm state, and other alarm devices remain unchanged; in entertainment venues, it is sometimes necessary to switch a part of all display screens to a certain program channel, while other display screens remain unchanged. [0003] The feature of the abo...
