Embodiment 1

[0027] An industrial-grade control cabinet, including a main control system 2, an auxiliary monitoring system 3 and a mechanical switching device 4, the main control system 2 and the auxiliary monitoring system 3 are connected to the same upper-level bus interface (not shown) that can exchange information with the upper-level controller 1 As shown in the figure), the main control system 2 and the auxiliary monitoring system 3 are both connected to the mechanical switching device 4, and the mechanical switching device 4 is connected to various equipment. Connect with main control system 2.

[0028] The main control system needs to realize many functions, so ARM is used, and the model can be STR710F. The auxiliary monitoring system only needs to realize data communication with the main control system, read the output signal of the main control system and store the preset signal, so adopt It can be realized by single-chip microcomputer, and the model can adopt 89C51 single-chip m...

Embodiment 2

[0034] A system security control method for an industrial-grade control cabinet, comprising the following steps:

[0035] Both the main control system and the auxiliary monitoring system obtain the same upper-level controller information through the upper-level bus interface. The auxiliary monitoring system performs physical monitoring of various signals output by the main control system in real time, and at the same time can perform data interaction with the main control system to obtain the main control system. The output signal of the system is backed up as a backup output signal;

[0036] The auxiliary monitoring system has an output safety value mode and a preset mode. The output safety value mode is an application mode in which the operation of the main control module ARM is normal, but the output signal is abnormal; the preset mode is the main core ARM of the main control system with built-in ARM Application mode of fixed signal without dynamic adjustment in fault state...

Embodiment 3

[0040] A system security control method for an industrial-grade control cabinet, comprising the following steps:

[0041] Both the main control system and the auxiliary monitoring system obtain the same upper-level controller information through the upper-level bus interface. The auxiliary monitoring system performs physical monitoring of various signals output by the main control system in real time, and can perform data interaction with the main control system at the same time to obtain the main control system. The output signal of the system is backed up as a backup output signal;

[0042] The auxiliary monitoring system has an output safety value mode and a preset mode. The output safety value mode is an application mode in which the operation of the main control module ARM is normal, but the output signal is abnormal; the preset mode is the main core ARM of the main control system with built-in ARM Application mode of fixed signal without dynamic adjustment in fault state...

Abstract

The invention discloses an industrial level control cabinet. The industrial level control cabinet comprises a master control system, an auxiliary monitoring system and a mechanical switching device. Asuperior controller is connected with the master control system and the auxiliary monitoring system, the master control system and the auxiliary monitoring system both are connected to the mechanicalswitching device, and the mechanical switching device is connected to various equipment. The master control system is embedded with the ARM, and a singlechip microcomputer is arranged in the auxiliary monitoring system. The invention also discloses a system safety control method of the industrial level control cabinet. By design of the invention, the auxiliary monitoring system with the built-insinglechip microcomputer is simple in structure in comparison with the master control system with the built-in ARM, thus, a system redundancy problem is avoided, and meanwhile, by an emergency mode ofmechanical switching, reliability and stability of the system are guaranteed.

Description

technical field [0001] The invention relates to the field of industrial digital circuits, in particular to an industrial-grade control cabinet and a system safety control method thereof. Background technique [0002] With the strengthening of people's awareness of industrial site safety responsibility, people pay more and more attention to the safety system measures of industrial sites. At present, the same two or more sets of backup systems are mostly used to monitor the operating status on the market. This method is not only complex in structure, redundant in system, and high in cost, but also brings difficulties to maintenance, failure, and repair. Not only that , which is only suitable for safety maintenance in general application sites. For the complex and uninterrupted industrial environment, in order to detect system damage and operation deviation problems in time during operation, and make corresponding protection, warning and automatic cut-in auxiliary operation mo...
