Description

Remote monitoring and metering management system for medical gas supply
Technical field the invention belongs to a kind of remote monitoring and metering management system for medical gas supply.
Background technology hospital medical gas commonly used has oxygen, negative pressure, compressed air, laughing gas (anesthetic gases), carbon dioxide etc.Before not having the central gas-supply system, hospital will use these gases, oxygen cylinder, vacuum extractor, air compressor and other bottled gas must be moved into ward or operating room and use, so both increase medical workers greatly, bring many hidden dangers again.So medical gas centralizedly supply system just arises at the historic moment.Every kind of gas will be realized centralizedly supply, all is made up of three parts, is respectively air feed station, pipe-line transportation system and gas consuming device.
Have the diformazan hospital that surpasses 50% or more all using medical central gas supply system at present, except manufacturer provides the after-sale service for hospital, substantially all there are sole duty or part-time system management attendant in hospital of every family.No matter be that producer provides after-sale service or hospital self carries out maintenance management, substantially all be in passive state, just go to handle after promptly waiting system to break down can not to use or to producer's newspaper barrier.So both influence the use of hospital, incured loss through delay maintenance time, and can increase maintenance cost again.In fact, if can accomplish periodically index parameters such as viewing system pressure, the service time of understanding gas flow, checkout equipment and operating temperature, just can accomplish the fault that system may occur is judged in advance, the real realization by passive change service initiatively, the factor that the system that influences is used reduces, and reduces after service cost simultaneously.
The GPRS technology is used with through more universal, and carrier communication is also used in fields such as electricity meter-readings to some extent, but does not see application as yet at medical field, is necessary the method and apparatus at the characteristics development of new of medical gas supply remote monitoring and metering management.
Summary of the invention purpose of the present invention is exactly will propose a kind ofly to realize remote monitoring and metering management system for medical gas supply long-range, real-time, Centralized Monitoring based on GPRS technology and carrier communication, to reduce the equipment fault in the medical gas supply process, improve the maintenance levels of air supply system, guarantee normal air feed.
This remote monitoring and metering management system for medical gas supply that the present invention proposes, it is characterized in that it is by carrier communication data collection station (being called for short data collection station or acquisition terminal), the data concentrator (being called for short data concentrator or concentrator) and the administrative center station (abbreviation central station) of band GPRS module constitute, described data collection station collection is distributed in information such as each section office of hospital and ward pipe end gas pressure flow, by power or the mains lighting supply circuit that spreads all over hospital, in the mode of spread spectrum carrier communication transfer of data is prepared data concentrator in the station to being installed on gas, data concentrator forwards the data to the Internet by GPRS communication link road, data are got back to the database server of central station by the Internet, by the operation conditions of the equipment put down in writing in the browsing database server, the running situation that is distributed in all clients of hospital of various places is implemented remote monitoring on the Internet for central station.
Described central station is made up of medical central gas supply system remote equipment management system for monitoring software and relevant device.Requirement has the fixedly website of domain name, and the GPRS terminal can initiatively be passed through the mobile gateway access server, and central station is confirmed to send the copy reading data command after the successful connection, and the data that need in the concentrator are read back among the data base.Because adopt terminal initiatively to connect the center, terminal uses common GPRS card of surfing Internet to use, and helps business promotion.When central station needs to connect the equipment of a certain hospital in real time, can dial and wake data concentrator up, make its central station that initiatively is linked back, after connecting, central station can the real time monitoring status of equipment.
For guaranteeing data security, database server should dispose one main one and be equipped with, and the Internet access service device is provided with software firewall, and Telnet is provided with strict authentication mechanism.
Described concentrator connects upper central station management system, accepts the order of central station management system and the data that active upload is gathered.Manage the next data collection station simultaneously, seek and set up the best relay communication path, accept and guarantee the Time of Day operation architecture for data collection station.
Concentrator uses secondary power supply distributed power supply mode, and transformator is with the direct current secondary power supply of 220V/380V civil power step-down rectifier filtering becoming 36V, and DC/DC DC converting technology is used in carrier modem, GSM/GPRS communication module and the power supply of computer plate.The secondary power supply balance each side's performance of power supply wide-voltage range, power supplying efficiency, lightning protection, power supply reliability and power supply cost, provide condition for concentrator uses battery powered simultaneously.
The modem of data concentrator electrification line spread spectrum carrier communication chip research and development is realized the power line carrier communication between mainboard and the terminal.
The carrier data concentrator is the important step of medical central gas supply system remote equipment management system for monitoring, connects upper central management system and the next carrier data acquisition terminal.The data of management system compile, all rely on concentrator to realize to the management of terminal data.Arrive central station administrative center by interval active upload data acquiescence or that be provided with.
Data collection station is the metering of afflux amount, flow measurement, transmitter data acquisition and the band carrier communication function of switching value state acquisition four unifications, the smart machine of liquid crystal display, have 2 road 4-20mA acquisition channels, the conversion accuracy of each passage is 0.03% of a full scale, range and multiplying power can be by the software settings, and on behalf of which kind of physical quantity, the data of each data collection station collection specifically defined by central database.
The present invention has following beneficial effect:
