Abstract
The utility model discloses a kind of subway station intelligent ventilating system based on PLC, entrance in subway station is provided for detecting the correlation infrared sensor of human body, correlation infrared sensor connects microcontroller, and microcontroller is connected to PLC by fieldbus；The frequency that microcontroller is triggered according to correlation infrared sensor judges the flow of the people size into subway station, and result of determination signal is sent into PLC；PLC is connected with draft fan unit, and the result of determination signal that PLC is sent according to microcontroller sends the instruction for increasing wind speed or the instruction for returning normal wind speed to draft fan unit.
Description
Technical field
The utility model is related to a kind of subway station intelligent ventilating system based on PLC.
Background technology
At present, domestic subway station (referring mainly to underground station) carries out the ventilation in station using draft fan unit
Regulation.Existing draft fan unit carries out environment and is adjusted to carry out air quantity output using the pattern for determining air quantity.On conventional ground
During iron operation management, because many factors such as extensive management mode, thin awareness of saving energy cause metro operation several
It is in lossing state.The part energy can not be saved, the characteristics of subway station large space, flow of the people change fast causes air quantity
Change relatively lags behind, it is impossible to the air quality effectively in regulation station.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and there is provided a kind of subway station intelligence based on PLC
Ventilating system.
The utility model is achieved through the following technical solutions：
A kind of subway station intelligent ventilating system based on PLC, the entrance in subway station is provided for detecting human body
Correlation infrared sensor, correlation infrared sensor connection microcontroller, microcontroller is connected to PLC by fieldbus and controlled
Device processed；The frequency that microcontroller is triggered according to correlation infrared sensor judges the flow of the people size into subway station,
And result of determination signal is sent to PLC；PLC is connected with draft fan unit, and PLC is according to micro-control
The result of determination signal that device processed is sent sends the instruction for increasing wind speed or the instruction for returning normal wind speed to draft fan unit.
In the above-mentioned technical solutions, PLC is also connected with monitoring server.
Advantage of the present utility model and have the beneficial effect that：
Subway station intelligent ventilating system of the present utility model based on PLC, can be big according to the flow of the people for entering station
The small ventilation speed to control draft fan unit in advance, accomplishes targetedly to control in advance, saves electric energy.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The technical solution of the utility model is further illustrated with reference to specific embodiment.
Referring to accompanying drawing 1, a kind of subway station intelligent ventilating system based on PLC involved by the utility model, including PLC
Controller,
Entrance in subway station sets correlation infrared sensor, and correlation infrared sensor connection microcontroller is (single
Piece machine), microcontroller (single-chip microcomputer) is connected to PLC by fieldbus；Detected by the correlation infrared sensor
Into the flow of the people of subway station, when someone enters entrance to the station, correlation infrared sensor is triggered, and (human body is sheltered from pair
After the infrared signal for penetrating formula infrared sensor, correlation infrared sensor is triggered once), now single-chip microcomputer detects correlation
The trigger signal of infrared sensor, the frequency that single-chip microcomputer is triggered according to correlation infrared sensor judges to enter subway station
Density of stream of people, and result of determination signal is sent to PLC.(for example, setting single-chip microcomputer every 15 seconds is a detection week
Phase, if in the detection cycle of 15 seconds, the number of times that correlation infrared sensor is triggered exceedes the threshold value (such as 30 times) of setting,
Then single-chip microcomputer judges that flow of the people is excessive, now sends the excessive signal of flow of the people to PLC；If in the inspection of next 15 seconds
In the survey cycle, the number of times that correlation infrared sensor is triggered is again less than the threshold value of setting, then single-chip microcomputer judgement flow of the people is normal,
Now flow of the people normal signal is sent to PLC).
PLC is connected with the draft fan unit of subway station, when PLC receives microcontroller (single-chip microcomputer)
After the excessive signal of flow of the people of transmission, PLC sends the instruction for increasing wind speed to draft fan unit, to increase in station
The ventilation speed in portion；After PLC receives the flow of the people normal signal of microcontroller (single-chip microcomputer) transmission, PLC
Controller sends back the instruction for normal wind speed of reforming to draft fan unit, the ventilation speed of draft fan unit is returned just
Often, to save the energy.
PLC is also connected with monitoring server, and the monitoring data of PLC is sent into monitoring server.
Exemplary description is done to the utility model above, it should explanation, do not departed from core of the present utility model
In the case of the heart, it is any it is simple deformation, modification or other skilled in the art can not spend creative work etc.
Protection domain of the present utility model is each fallen within replacing.
