The shortcoming of such scheme is: one, wiring is many, and each sensor must have 2 power leads, 2 output lines, 13 wiring of each some needs; Two, wiring is long, because all data will focus on collector, all output lines all will be linked on collector, and every root line length is all at about 5 meters; Each sensor needs the unified power supply of collector, and every root power lead on average also wants 5 meters.Three, because of the mode many (having 4 ~ 20MA analog quantity, dry contact, low and high level) that sensor exports, collector manufactures difficult increase, can increase cost; Four, the transmission range of analog quantity is generally about 50 meters, and antijamming capability is not fine.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the prior art Problems existing in above-mentioned background technology, a kind of Combined outdoor communications equipment room environmental parameter monitoring device is provided, decrease hardware, simplify system, eliminate the collector in existing scheme, decrease most wiring, hardware cost and productive manpower cost all have and significantly reduce.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Combined outdoor communications equipment room environmental parameter monitoring device, has temperature sensor, humidity sensor, smoke transducer, water logging electrode, AD sampling A/D chip, photoelectric isolated chip, microprocessor, Switching Power Supply and communication interface; By the analog signals of AD sampling A/D chip collecting temperature sensor, humidity sensor, the dry contact signal of smoke transducer and the low and high level signal of water logging electrode is gathered by photoelectric isolated chip, the signal collected separately is sent to microprocessor by AD sampling A/D chip and photoelectric isolated chip, upload the data to higher level's supervisory system by microprocessor again by after the protocol code of standard by communication interface.
Further specifically, temperature sensor, humidity sensor, smoke transducer are all welded on master control borad, and are connected with corresponding acquisition chip by the copper cash that covers of wiring board, provide working power by Switching Power Supply unification to it.
Further specifically, what smoke transducer adopted is dry contact output transducer.
The invention has the beneficial effects as follows: a kind of Combined outdoor communications equipment room environmental parameter monitoring device of the present invention, integrated multiple sensor, the collection of all environmental parameters of a complete field outdoor communication equipment room point, upload, alarming processing etc., greatly reduce hardware cost, labour's manufacturing cost, substantially increase efficiency.
