The mine security defending system has the advantages that the structure is simple, the cost is low, large-scale application is facilitated, and security of the mine automatic production line can be effectively improved due to the use of the infrared electronic fences.
Description
Technical field
The utility model relates to industrial process to be controlled and safety protection field, relates to specifically the personal safety protecting system in a kind of mine automation production line.
Background technology
In colliery or coal preparation plant be seen everywhere some adhesive tape conveyors, scraper conveyer and vibrating mechanical equipment that some are large-scale.The today of day by day improving in process automation, the start-stop of these equipment often operates by the collection control of centralized control chamber, or passes through program flow control.Collection control operator often cannot fully understand the security protection operating mode that equipment is real-time.Particularly, when flow process is controlled, the start/stop time interval between upstream and downstream equipment only has the time in several seconds, and operator has little time to fully understand the security protection operating mode of every equipment especially.
Current common way is on every equipment, safety guide rail to be installed as much as possible.In addition, operator is when system equipment start-stop in collection control, first by acousto-optic early warning, by post work custodial care facility periphery situation, then by platform start-stop equipment.No longer acousto-optic early warning after equipment all moves.There is following drawback in such way:
1, the main equipment having cannot or inconvenience do comprehensive safety guide rail.Such as: after installing guard rail additional, be not easy to maintenance;
2, post work custodial care facility periphery situation comprehensively.Such as: one reach 300 meters from adhesive tape conveyor, often only join 1 post work;
3, need all the time to come by strengthen personnel's awareness of safety in management the safe operation of back-up system.When having external staff to enter or new post work enters, can increase the security risk of system.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of personal safety protecting system being widely used in mine automation production line, and it is simple in structure, with low cost, effectively raises the security of mining automatic production line.
The technical scheme that the utility model adopts is: a kind of mine safety guard system, comprise PLC control system, HMI supervisory system and at least 1 infrared exoelectron fence, described PLC control system comprises the PLC controller I/O substation that a GePLC controller main website, acousto-optic voice alarm device are connected with a plurality of YuPLC controller main website, described acousto-optic voice alarm device is all connected with PLC controller I/O substation with infrared exoelectron fence, and described PLC controller main website is connected with HMI supervisory system.
Described infrared exoelectron fence is a kind of of infrared safe light curtain or infrared safe grating.
The beneficial effects of the utility model: the utility model is simple in structure, with low cost, be applicable to large-scale application, the use of infrared exoelectron fence has effectively improved the security of mining automatic production line.
Accompanying drawing explanation
Fig. 1 is structural framing figure of the present utility model.
Embodiment
As shown in the figure, a kind of mine safety guard system, comprise PLC control system, HMI supervisory system and at least 1 infrared exoelectron fence, described PLC control system comprises the PLC controller I/O substation that a GePLC controller main website, acousto-optic voice alarm device are connected with a plurality of YuPLC controller main website, described acousto-optic voice alarm device is all connected with PLC controller I/O substation with infrared exoelectron fence, described PLC controller main website is connected with HMI supervisory system, and described infrared exoelectron fence is a kind of of infrared safe light curtain or infrared safe grating.
In the course of the work, native system is comprised of infrared exoelectron fence, PLC control system and HMI supervisory system the utility model.Infrared exoelectron fence is specifically determined its installation quantity according to the number of devices that needs security protection in system.Infrared exoelectron fence can be infrared safe light curtain, can be also infrared safe grating, in order to isolate equipment operation area and pedestrains safety region in industrial and mineral production system.It is arranged on equipment periphery, according to the physical characteristics of equipment and necessary safe distance Reasonable Arrangement.Infrared exoelectron fence is connected on the distributed I/O substation in PLC control system nearby, is convenient to the security information in the real-time collection production system of PLC control system.Meanwhile, the positional information that can install according to electronic grille fence is carried out geocoding.
PLC control system is the core in industrial and mineral mechanized production system, and it is for the signal collecting and controlling of flow sheet equipment.Also be used for the security information being detected by infrared exoelectron fence in acquisition system here.Acousto-optic language warning device is also installed in PLC control system, for the production of the fault alarm in process, and early warning in particular cases.In native system, PLC control system, according to the physical distribution situation of process device, adopts distributed I/O networking, centralized control.
HMI supervisory system, is arranged on production central station of floating dock, and it is connected with PLC control system, in order to implement supervision production run situation and production run is carried out to manual control.
The adhesive tape conveyor of take is example: when the active force electricity input of adhesive tape conveyor, equipment is when waiting for running status, and the infrared exoelectron fence that is arranged on its periphery is also devoted oneself to work simultaneously.On the contrary, if the active force of equipment electricity does not drop into, infrared exoelectron fence can not put into operation yet.When the power that can't detect this equipment when PLC controller drops into signal and infrared exoelectron barrier gate signal, just in HMI central monitoring system, show relevant information.
When the power electric of adhesive tape conveyor drops into, infrared exoelectron fence does not detect alerting signal, and when this equipment does not have the alerting signal of other influences equipment operation yet, the logical program of PLC just allows this equipment to prepare to open car, and in HMI system display device in preparing running status.When PLC detect button from device context open car signal or from central station of floating dock open car signal time, adhesive tape conveyor just can start up smoothly.After equipment operation, the running status of surveillance equipment and the state of security protection system that HMI supervisory system can be real-time.
When adhesive tape conveyor is in the process of operation, there are personnel to be strayed into the region of infrared exoelectron fence, infrared exoelectron fence can be real-time fox message is sent to PLC control system, the logical program of PLC is this adhesive tape conveyor of emergency outage accordingly, sends alerting signal by acousto-optic voice alarm device simultaneously.HMI supervisory system also can be real-time display device stopped status and shut down reason.
By above description, can see the prevention and control process of security protection system.Especially, this guard system is for some hazardous areas, and in order to prompting, personnel take care.Such as in industrial and mineral, some use place and some dangerous high voltage places in radioactive nucleus source.
The utility model is simple in structure, with low cost, is applicable to large-scale application, and the use of infrared exoelectron fence has effectively improved the security of mining automatic production line.
