Dual-backup network light control desk and control method

Abstract

The invention relates to a dual-backup network light control desk and a control method. The light control desk comprises a plurality of groups of data source input modules, two same core integrated processors and an output module, wherein each group of data source input modules at least consists of two or more control units; the data source input modules are connected with the two core integrated processors respectively; each core integrated processor backs up data transmitted by each data source input module and operates backup data; the two core integrated processors are connected with the output module respectively; operation results of the two core integrated processors are compared with each other and transmitted to the output module so as to output a corresponding command. Accordingly, embedded core integrated processors are used for replacing a conventional PC system computer, so low cost is achieved and problems existing in the conventional PC system computer are solved. Simultaneously, the two core integrated processors can be used for achieving dual-backup network connection to meet the requirement of real-time detection of data synchronization well, so that a lighting engineer can know the running conditions of a console.

Description

technical field [0001] The invention relates to the technology in the field of dimming consoles, in particular to a double-backup network dimming console and a control method. Background technique [0002] Professional stage dimming consoles require large control loops. The existing large loop dimming consoles (more than 2000 loops) use standard PC computer systems to process a large amount of control data in order to meet the requirements of large-capacity and high-speed data processing. The computer system is used as the main processing unit, which must be managed by an operating system, such as DOS, Windows, etc., and storage devices such as hard drives must be configured at the same time. Some PC systems have removable memory sticks, CPUs, hard disks, ISA and PCI slots. Transportation, humidity, dust, and oxidation of connectors will all cause system failures. At present, the existing dimming consoles cannot solve the problem of real-time detection data synchronization,...

Problems solved by technology

[0002] Professional stage dimming consoles require large control loops. The existing large loop dimming consoles (more than 2000 loops) use standard PC computer systems to process a large amount of control data in order to meet the requirements of large-capacity and high-speed data processing. The computer system is used as the main processing unit, which must be managed by an operating system, such as DOS, Windows, etc., and storage devices such as hard drives must be configured at the same time. There are PC systems with removable memory sticks, CPU, hard disk, ISA and PCI slots, transportation, humidity, dust, connector oxidation, etc. will cause system failures

At present, the existing dimming consoles cannot solve the problem of real-time detection data synchronization, which brings troubles to the analysis of the lighting engineer; moreover, because the stage lighting control equipment has a large number of control units (that is, data sources) such as fader potentiometers, Buttons are used as replay tools (for example, each push rod potentiometer records 2048 grids of data), in the traditional control process, only to operate any tool, all the internal data must participate in the calculation, making the entire calculation data large and resulting in calculation Slow, far beyond the specified computing cycle, can no longer meet the needs of today's development
