Abstract
The utility model provides an intelligent monitoring device for temperature and humidity of archives. The whole device comprise four parts: a window automatic controller (WinAC) master control station, a programmable logic controller (PLC) slave station, a temperature and humidity control system and a ventilation control system, wherein the WinAC master control station and the PLC slave station are connected through a Profibus-data processing (Profibus-DP) interface module to carry out data communication; the temperature and the humidity of the archives can be automatically detected and data of the temperature and the humidity can be displayed and stored; when the temperature and the humidity exceed set values, an air conditioner and ventilation equipment can be automatically regulated and controlled, and simultaneously, the intelligent monitoring device also has a fault alarm function and an error prevention operation function; an operation staff can set the air-out temperature and humidity parameters of the archives in a central control room according to the actual requirements, monitors the operation condition of equipment in each archive and prints operation parameters and an operation curve; and by adopting a distributed control modular structure, monitoring items and the number of measurement and control points can be increased at any time through an extension interface.
Description
Technical field
The utility model is that a kind of totally digitilized temperature, Humidity Detection and Ventilation Control based on the Profibus-DP fieldbus is the intelligent archives humiture measure and control device of one.
Background technology
The preservation quality of archives, anticorrosion mildew-resistant all have very big relation with archives stock's temperature and humidity, in case the temperature and humidity of file store is out of control, the archives conservation problem is just extremely urgent.At present, regulating timely and effectively and temperature and the humidity of controlling storage area, and according to circumstances make measures areput, is the key of protection and prolongation life time of archive.Automatically detect the temperature and humidity of storage area fast and accurately, very important meaning is arranged for the life-span of improving archives.
Summary of the invention
The warm and humid detection system of intelligent file store that it is one that the utility model has aimed to provide a kind of totally digitilized temperature, Humidity Detection and Ventilation Control based on the Profibus-DP fieldbus, system architecture is simple, be easy to expand, and has characteristics such as waterproof is anti-lightning strike, corrosion-resistant.The staff of file store can pass through computing machine, archives warehouse temperature and the real-time testing result of humidity in the comprehensive understanding 24 hours, and the historical detection record of file store.System has detection measurement, communication regulation and control, data presentation printing, multimode warning and accident treatment measure prompt facility.
The utility model is provided with WinAC master station, S7-200PLC slave station and I/O configuration, temperature and humidity control system, four ingredients of ventilated control system.For realizing the function of WinAC, the WinAC master station is by the data communication of carrying out between Profibus-DP interface module and the PLC; The PLC slave station is made up of Siemens PLC CS7-200 and LTM8303 deconcentrator module, and interconnect by serial port, archive office's temperature and humidity control system is made up of 3 parts such as DS18B20 digital temperature sensor, LTM8820 " one-wire bus " humiture probe, control blower fans.
The utility model is to realize monitoring like this: archives supervisory system team control distributed frame figure as shown in Figure 1, constitute typical field bus control system by upper industrial computer with based on site intelligent node and the I/O module thereof of Profibus-DP, the main control module of Profibus-DP fieldbus has been selected the WinAC based on WindowsNT of Siemens for use, system's host computer is both as the soft controller of PLC like this, bear remote control function, again as monitoring management computer.The PLC slave station is made up of Siemens S7-200 and LTM8303 deconcentrator module, and interconnects by serial port.Ventilated control system is made up of PLC slave station control of conversion device and blower fan group, and control command is sent by master controller.
The beneficial effects of the utility model are: can realize the humiture of 24 hours full-automatic detection file stores and demonstration, the preservation of data thereof, but auto-control air-conditioning and water pump are regulated when humiture surpasses setting value, also have multiple mode accident alarming, anti-misoperation function and crucial operational factor display setting hold function simultaneously.Operating personnel can be according to actual needs in parameters such as the leaving air temp of central control room setting file chamber, humidity, monitor the ruuning situation of each archive office's equipment and print operational factor and curve.
Description of drawings
Fig. 1 is the temperature and humidity monitor bus structure figure of archive office.
Embodiment
The supervisory system team control distributed frame figure of archive office sees shown in Figure 1, constitute typical field bus control system by upper industrial computer with based on site intelligent node and the I/O module thereof of Profibus-DP, the main control module of Profibus-DP fieldbus has been selected the WinAC based on WindowsNT of Siemens for use, system's host computer is both as the soft controller of PLC like this, bear remote control function, again as monitoring management computer.For realizing the function of WinAC, a Profibus-DP is installed on the host computer server, interface module CP5611, the WinAC Control Engine is carried out data communication by Profibus-DP interface module disk 611 and distributed director and is finished task such as communicate by letter between data acquisition, analysis and Control, PC and the PLC.Slave station is made up of Siemens S7-200PLC and LTM8303 deconcentrator module, and interconnects by serial port.Regularly send order to the LTM8303 module by PLC by serial ports, the LTM8303 module sends back PLC with corresponding measurement data after receiving order, by the Profibus-DP bus data is sent to master station by PLC centralized calculation, processing again.Each deconcentrator module can articulate 8 road temperature and humidity measurement cables, measures 8 temperature and humidity measurement points of cable mixed-arrangement for every, and single like this deconcentrator module can be arranged 64 measurement points.Archive office's temperature and humidity control system hardware mainly comprises DS18B20 digital temperature sensor and LTM8820 " one-wire bus " humiture probe.The Ventilation Control device is to drive the blower fan group by slave computer PLC slave station control of conversion device to finish, and control command is sent by master controller.Can adopt air draught type and blowing-type to ventilate according to the purpose of ventilating (cooling or hydrofuge), but not only can whole Ventilation Control but also local ventilation control.While is measured the air output that the temperature and humidity value is controlled blower fan according to Temperature Humidity Sensor around being distributed in the air channel, to prevent air channel dewfall on every side, influences the storage effect of archives.
