Description of drawings
Fig. 1 is system construction drawing of the present invention.
Embodiment
Below with reference to accompanying drawing, technical scheme of the present invention is elaborated.
A kind of Scientific Research in University Laboratory intelligent monitor system as shown in Figure 1 comprises between laboratory field apparatus, light current and the monitoring management PC.In the present embodiment, the laboratory field apparatus is provided with N, and N is natural number, is arranged at different laboratories.Described laboratory field apparatus inclusion information input media, sensor and output device, and message input device, sensor and output device are connected between aforesaid light current with wired mode respectively; In the present embodiment, have M between described light current, M is identical with number of floor levels, comprises between the light current of every floor corresponding to the PLC field controller in each laboratory of this floor and the PLC centralized control equipment of this floor.
Be used for input user profile by place a text input device Siemens TD200 on each doorway, laboratory; Measure intensity of illumination at each experiment indoor location light sensor; Measure smokescope at each experiment indoor location gas sensor; A pair of optoelectronic switch is respectively installed in the interior outside at door, is used for statistical number of person; Air velocity transducer is installed in outside window, is used for measuring extraneous wind speed size.
The on-site signal of the collection of each sensor and the user profile of TD200 input are sent between the light current of laboratory building, placed the PLC corresponding to the centralized control equipment S7-300 series of the PLC of the field controller S7-200 series in each laboratory and every floor between light current, adopt Profibus DP to communicate by letter between field controller PLC and the centralized control equipment PLC, each PLC field controller receives respectively on-site signal and the user profile that the laboratory field apparatus corresponding with it sends, and send the PLC centralized control equipment of corresponding floor to, the PLC centralized control equipment sends on-site signal and the user profile that receives to the monitoring management PC by Ethernet switch again, by in the monitoring management PC, embedding monitoring software---the MCGS configuration software is write VB or VC program, realize the report printing of laboratory operating position, statistical study etc., the parameter control signal that the monitoring management PC can also be sent simultaneously sends the PLC centralized control equipment to, receive parameter control signal by the PLC field controller again and send the output device of the laboratory field apparatus corresponding with it to, realize the various device in remote auto control laboratory, guarantee that the laboratory is high efficiency to operate.
When having the people to enter the laboratory, the optoelectronic switch that is contained in outer side of door moves first, moves after being placed on the optoelectronic switch of an inboard, and the expression laboratory enters a people; When having the people to leave the laboratory, the inboard optoelectronic switch of door moves first, moves behind the optoelectronic switch of outer side of door, and a people is left in the expression laboratory, thus the indoor number of statistical experiment.The light sensor that is contained in the laboratory gathers indoor intensity of illumination, the monitoring management PC carries out real-time PID control according to the number in the laboratory and intensity of illumination to the lighting device in the laboratory, and in the situation that indoor unmanned, the autoshutdown door and window avoids theft.The wind velocity signal that the monitoring management PC gathers according to the air velocity transducer that is contained in outside window, the keying of warning device is controlled in the keying of control window according to the signal of the gas sensor collection in the laboratory.
