Abstract
The utility model discloses an access control system for a waste incineration power plant. The access control system comprises an entrance guard and an entrance guard management mainframe connected with the entrance guard, wherein the entrance guard management mainframe is connected with a distributed control system through an OPC (OLE for Process Control) interface; a sensor arranged in an entrance guard area is connected with the distributed control system through a 4-20 mA electric signal. The working principle of the access control system is as follows: the entrance guard transmits personal information far away to the entrance guard management mainframe, receives and executes a command of opening the door from the entrance guard management mainframe, the entrance guard management mainframe is used for judging whether the person has a permission to enter and inquiring the distributed control system to determine whether the entering area is safe, and if the person has a permission to enter and the entering area is safe, the entrance guard management mainframe sends the command of opening the door to the entrance guard. The access control system is reasonable in design, strengthens the management of the waste incineration power plant, and improves the safety of production and management of the waste incineration power plant.
Description
Technical field
The utility model relates to a kind of access control system, particularly a kind of access control system for garbage incinerating power plant.
Background technology
Garbage incinerating power plant from garbage transporting to charging, boiler burning, percolate processing, lime-ash processing, desulphurization denitration be to release, the electric power transfer of line of electric force etc. of flyash curing, vapor pressure, has been full of high temperature, fire and the toxic and harmful harm misgivings to fuels sources, equipment and operations staff and whole power plant safety in each link.For guaranteeing production safety, carrying out smoothly, and effectively control, management operating personnel's normal discrepancy just seems very important.
Whether conventional access control system can only enter by personnel's control of authority, cannot enter region by perception and control and enter safely, enters although can meet a requirement point authority for management, can not support personnel's life security.
Summary of the invention
For the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of access control system for garbage incinerating power plant, can meet point authority simultaneously and enter and control the requirement that personal security enters.
For achieving the above object, the utility model is by the following technical solutions: a kind of gate control system for garbage incinerating power plant, comprise the entrance guard management main frame that gate inhibition is connected with gate inhibition, described entrance guard management main frame is connected with Distributed Control System (DCS) by OPC interface, and the sensor being arranged in gated area is connected with Distributed Control System (DCS) by 4～20mA electric signal.
Described sensor is one or more the combination in smokescope sensor or temperature sensor or sensing methane concentration device.
Owing to having adopted above technical scheme, the beneficial effects of the utility model are:
The feature that the utility model is produced for garbage incinerating power plant, to sensor is set in gated area, the smokescope in gated area, temperature, methane concentration are sent in real time Distributed Control System (DCS) by sensor, Distributed Control System (DCS) is analyzed the real time data of sensor collection, judge whether safety of gated area, in the time having personnel to ask to enter gated area, entrance guard management main frame sends inquiry request to Distributed Control System (DCS), if gated area is safety, entrance guard management main frame sends to gate inhibition the instruction of opening the door, otherwise forbids opening the door.The utility model is reasonable in design, has strengthened the management of garbage incinerating power plant, and has improved the security of garbage incinerating power plant production and operation.
Brief description of the drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below to by reference to the accompanying drawings this utility model being described in further detail.
As shown in Figure 1, a kind of access control system for garbage incinerating power plant, described access control system is made up of gate inhibition 1, entrance guard management main frame 2, Distributed Control System (DCS) 3, sensor 4.
Gate inhibition 1 is connected by Ethernet is two-way with entrance guard management main frame 2, entrance guard management main frame 2 is connected by OPC interface is two-way with Distributed Control System (DCS) 3, sensor 4 is set in gated area, sensor 4 is one or more the combination in smokescope sensor or temperature sensor or sensing methane concentration device, according to the feature in garbage incinerating power plant gate inhibition 1 region, corresponding sensor 4 is set, as discharging hall arranges smokescope sensor, garbage pool region division methane depth detection sensor, percolate region division temperature sensor and sensing methane concentration device, the sensor 4 being arranged in gated area is connected with Distributed Control System (DCS) 3 by 4～20mA electric signal, sensor 4 is by all kinds of ambient condition parameters in gate inhibition 1 region, as temperature, smokescope, toxic and harmful concentration is converted to 4～20mA electric signal, and real-time Transmission is to Distributed Control System (DCS) 3, Distributed Control System (DCS) 3 is collected the 4～20mA electric signal sending from the sensor in each gate inhibition 3 regions continuously, and carry out real-time analysis judgement, determine whether safety of corresponding gate inhibition 1 region, in the time having personnel to enter gate inhibition 1 region by the request of swiping the card, gate inhibition 1 sends to entrance guard management main frame 2 request of entering, enter to ask for instructions and comprise personnel's personally identifiable information, after entrance guard management main frame 2 receives and enters and ask for instructions, inquire about built-in Access Control List (ACL), determine whether personnel have authority to enter gate inhibition 1 region, if personnel have authority to enter, entrance guard management main frame 2 sends inquiry request to Distributed Control System (DCS) 3 simultaneously, determine whether safety of gate inhibition 1 region, if now safety of gate inhibition 1 region, entrance guard management main frame 2 sends to gate inhibition 1 instruction of opening the door, if personnel's lack of competence enters gate inhibition 1 region or gate inhibition 1 region is current dangerous, entrance guard management main frame 2 sends and forbids the index of opening the door to gate inhibition 1, give the alarm on the spot gate inhibition 1 simultaneously.When running into special circumstances, when personnel must enter the gate inhibition's 1 regional processing emergency in unsafe condition, can enter by interim mandate of entrance guard management main frame 2.
Claims (2)
1. the access control system for garbage incinerating power plant, comprise that the entrance guard management main frame (2) that gate inhibition (1) is connected with gate inhibition (1) is characterized in that: described entrance guard management main frame (2) is connected with Distributed Control System (DCS) (3) by OPC interface, the sensor (4) being arranged in gate inhibition (1) region is connected with Distributed Control System (DCS) (3) by 4～20mA electric signal.
2. as right 1 requires described a kind of access control system for garbage incinerating power plant, it is characterized in that: described sensor (4) is one or more the combination in smokescope sensor or temperature sensor or sensing methane concentration device.
