Description
Technical field
The utility model relates to a kind of control system security protection module, and specifically, control system security protection module has related to a kind of control system security protection module that still can control equipment when controller damages.
Background technology
Existing control system comprises controller, by duty and the adjusting device of monitoring control devices equipment, with this protection equipment.But severe due to controller working environment, easily causes controller to damage, if controller can not be when equipment goes wrong timely closing device, will cause device damage even to occur safety problem.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art; thereby a kind of design science, simple in structure, good reliability are provided and regulate and control control system security protection module timely; this control system security protection module can be when controller controls environment damage; in time equipment is regulated and controled, prevent device damage.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of control system security protection module, it comprises central processor unit, CANBUS communication unit, data acquisition unit, relay unit and alarm unit, described central processor unit is connected with described data acquisition unit for passing through this data acquisition unit collecting device work state information, described central processor unit is connected with described CANBUS communication unit for monitoring this controller running status by this CANBUS communication unit and taking over the control work to equipment when this controller failure, described central processor unit is connected with described relay unit for pass through described relay unit closing device when equipment breaks down, described central processor unit connects described alarm unit.
Based on above-mentioned, described data acquisition unit comprises a plurality of sensors for collecting device work state information.
Based on above-mentioned, described alarm unit comprises loudspeaker.
The relative prior art of the utility model has substantive distinguishing features and progress, specifically, the utility model and controller are used in conjunction with, after controller controlling unit goes wrong, this control system security protection module can be controlled equipment rapidly, prevents device damage; Data acquisition unit collecting device work state information, for example: equipment rotary speed information etc., described central processor unit and the communication of described CANBUS communication unit, and the control work of adapter to equipment when this controller failure, described central processor unit is connected with described relay unit for pass through described relay unit closing device when equipment breaks down, and described central processor unit connects described alarm unit for reporting to the police; Described central processor unit is by described CANBUS communication unit and controller communication, whether the equipment working state information that the equipment working state that data acquisition unit can be collected and controller collect is compared, monitor this control system security protection module work with this; It has design science, simple in structure, good reliability and regulates and controls advantage timely.
Accompanying drawing explanation
Fig. 1 is the system chart of control system security protection module in the utility model embodiment.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of control system security protection module, it comprises central processor unit, CANBUS communication unit, data acquisition unit, relay unit and alarm unit, described central processor unit is for example connected with described data acquisition unit, for passing through this data acquisition unit collecting device work state information: the rotary speed information of direct collecting device; Described central processor unit is connected with described CANBUS communication unit for monitoring this controller running status by this CANBUS communication unit and taking over the control work to equipment when this controller failure, described central processor unit is connected with described relay unit for pass through described relay unit closing device when equipment breaks down, and described central processor unit connects described alarm unit.
Described central processor unit connects controller by described CANBUS communication unit, controller can gather the work state information of equipment comprehensively, controller receives by CANBUS communication unit the facility information that described data acquisition unit collects, compare by analysis with the equipment working state information that controller self collects, monitor this control system security protection module and whether work; Meanwhile, described central processor unit connects controller by described CANBUS communication unit, monitors this controller running status and when this controller failure, takes over the control work to equipment.When controller can not normal regulation equipment, this control system security protection module replaces controller to carry out equipment regulation and control in time; Described central processor unit connects described alarm unit, when described relay unit closing device, utilizes loudspeaker to carry out sounding alarm.
This control system security protection module volume is little, wiring simple, convenient operation, can when controller goes wrong, in time equipment be regulated and controled, and assurance equipment normally moves, for equipment provides a necessary protection module.Adopt CANBUS communication unit message transmission rate high, can carry out fast data transmission, after controller controlling unit lost efficacy, this control system security protection module is taken over the control to equipment in time.
Between described central processor unit, described CANBUS communication unit and controller, adopt MODBUS communications protocol, compatible good, applicability extensively need not be changed agreement and can be connected with various controller, is used to refer to equipment working state.
Described controller carries out message exchange by CANBUS communication unit and described central processor unit; with this, judge whether this control system security protection module works; simultaneously; the control command that described central processor unit sends according to controller, judges whether that starting relay unit regulates and controls equipment.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
