Problems solved by technology

The disadvantages of the fire alarm control device and its control method are: the total number of control units that can be set in the system is limited, up to 1024. When the number of controlled devices is large, multiple fire alarm control devices need to be used at the same time, which not only occupies place, and the operation of the bus linkage operation key 3 is very complicated, and it is impossible to perform the same operation on multiple modules at the same time

Embodiment

[0026] A bus linkage control method used in a fire alarm control system is as follows:

[0027] The first step is to compile a program with C51 language and run it on the bus linkage control keyboard 9;

[0028] The second step is to set the fire compartment number on the number key group 6, set the controlled equipment type on the category key group 8, and display the currently set machine number fire compartment number and the controlled equipment type on the liquid crystal display 5;

[0029] The third step is to search out the circuit number point number of the controlled device corresponding to the set condition by the operation key group, and display it on the LCD screen, and then send the searched circuit number point number of the controlled device to the Fire alarm controller implementation.

[0030] like image 3 As shown, it is a structural schematic diagram of a fire alarm control device of the present invention, and the fire alarm control device is composed of a...

Abstract

The invention relates to a bus gang control method which is applied to a fire alarm control system. The bus gang control method is characterized in that: the program is programed in C51 language and applied to a bus gang control keyboard of a fire alarm control device; a fire protection division code is arranged on a number key set while the types of controlled equipment is arranged on a type key set; the currently set machine codes, fire protection division codes and the types of controlled equipment are displayed on an LCD; a site code of a loop code of the controlled equipment corresponding to the set conditions is found out by an operation key set and displayed on the LCD, and then sent to the fire alarm controller for execution. The bus gang control method of the invention has the advantages that the number of controlled objects in each fire alarm control system can be as many as 4,800, less panel space is occupied and the operation is simple.

Description

technical field [0001] The invention relates to a bus linkage control method used in a fire alarm control system, belonging to the technical field of fire alarm control. Background technique [0002] At present, the bus linkage control method used in the fire alarm control system is as follows: figure 1 As shown, the fire alarm controller of a fire alarm control system can connect up to 16 control panels for control, and each control panel is as follows figure 2 As shown, it is composed of 64 control units, and each control unit is composed of a bus linkage prompt indicator light 1, a bus linkage feedback indicator light 2, and a bus linkage operation key 3. The bus linkage prompt indicator light 1 is the controlled object of the control unit. It lights up when the action command is issued, and the bus linkage feedback indicator light 2 lights up when it receives the action feedback signal of the controlled object of the control unit. The bus linkage operation key 3 contro...
