Problems solved by technology

For example, in the production of steel rolling, from the automatic temperature control system of the heating furnace, the rolling steel reduction control system, and the automatic quenching control system after rolling, etc., the computer crashes of each system will occur randomly, and it takes at least a few seconds or several seconds to wait for the crash. Ten seconds, during this period, the equipment is out of control, which is very likely to cause production and equipment accidents for the equipment in operation. The light ones cause production stoppages, scrap steel, etc., and the severe ones cause equipment damage, leading to major accidents and huge losses.

Embodiment 1

[0021] Example 1. Industrial control computer redundant protection device

[0022]The specific structure of the industrial control computer redundant protection device of this embodiment is shown in conjunction with FIGS. 1 to 6. Its function is that when the industrial control computer system crashes randomly, the backup computer of the system will automatically start the substitute and help the crash reset as a backup. It is the redundant electronic protection device of the industrial control computer system itself. The device can have a casing, etc. It is set up between two, or three, or more redundant computers that make up the redundancy, and can monitor each other online in real time and can automatically switch the protection of the electronic protection device. Figures 1 to 3 are part of the schematic diagram of a complete set of electronic circuits for monitoring between two computers that form a redundancy, and Figures 4 to 6 are another part of a schematic diagram of a ...

Embodiment 2

[0023] Embodiment 2. Industrial control computer redundant protection device

[0024] The general structure of the industrial control computer redundant protection device of this embodiment can be shown in conjunction with FIGS. 1 to 6. The difference from the first embodiment is: 1. There are three redundant computers, such as A (1 machine), B (2 machine) and C (3 machine), which are real-time online monitoring of each other and automatically switch protection. The redundant protection device. Of course, there must be three sets of redundant protection electronic circuits. 2. The electronic circuit used can be a circuit with a structure different from that shown in Figures 1 to 6, or different electronic components, as long as it can complete or realize the functions shown in Figures 1 to 6. The rest of the undescribed items are all the same as those described in the first embodiment and will not be repeated.

Abstract

The invention provides an industry control computer abundant protector belonging to industry control technical field, which is an abundant automatic electric protector of computer system, composed of electric protective circuits with real-time online detection automatic switch interaction, arranged between abundant computers, which comprises a work abnormal real-time online detect circuit, an automatic switch protect circuit, and relative automatic switch circuits as start, abundant, return or the like. The invention can build computer active / backup automatic abundant protect system for resolving the stable industry control problem of computer, to realize stable and reliable industry control, to improve the automatic control level of computer industry, with simple structure, reasonable design, reliable technique, stable operation, high practicality, and wide application.

Description

1. Technical Field [0001] The industrial control computer redundancy protection device disclosed in the present invention belongs to the technical field of industrial control, and specifically relates to an automatic redundancy protection device that works abnormally or fails in an industrial control computer system-such as automatic switching when the machine crashes, and the machine crashes back to normal. . 2. Background technology [0002] In computer automatic control systems, no matter how reliable the system is, computer crashes have always been an unavoidable phenomenon and problem. This problem is also a serious problem that plagues the stable operation of the system, a common problem in the field of industrial automatic control, and even more so. Problems that are difficult to solve and deal with in the field of control. For example, in the production of steel rolling, from the automatic temperature control system of the heating furnace, the rolling reduction control sy...
