Embodiment
Below describe and realize the present invention for disclosing the present invention to enable those skilled in the art.Preferred embodiment in below describing only as an example, it may occur to persons skilled in the art that other apparent modification.
As shown in right Fig. 1, a kind of medical air monitoring by ModBus protocol realization and warning system, comprise monitoring server, information collecting device, transcriber, warning transmitter.
Monitoring server is a special server.For the Real-Time Monitoring medical treatment air pressure of air, dew point value and air compressor machine supply voltage information.
Information collecting device comprises the pressure unit, electric transducer formula dew point hygrometer and the supply voltage checkout equipment that meet industrial control standard, for gathering the supply voltage of the air pressure of medical air, dew point and air compressor.Wherein, pressure unit and electric transducer formula dew point hygrometer can export the electric signal of 4-20mA, utilize transcriber that this electric signal is transformed into digital signal, are communicated by ModBus bus with monitoring server.Supply voltage checkout equipment is for gathering and detect the voltage signal of air compressor, and this voltage signal is transformed into digital signal, by ModBus bus, by digital signal transfers to monitoring server by recycling transcriber.
Above-mentioned ModBus bus is finally connected with monitoring server, and then constitute centralized monitoring system by RS232 interface.
Panalarm is used for when exception appears in the state of medical air or monitoring equipment connects fault, and supervisory system can pass through panalarm, and the alarming short message with relevant information is sent to user mobile phone in time.
The monitoring of medical treatment air and warning system are the systems of a set of Codesign, and in the private server that Integrated Simulation carries in system, software systems run on Linux platform.
By development centre monitoring software; the data monitored are realized real-time constitutional diagram display, editor; there is different security permissions; record data that can be detailed; can inquire about easily, in time, efficiently and accurately warning information can be sent to operator on duty and person in charge by the form of SMS when Monitoring Data exception or monitoring equipment fault.
The design of the monitoring of medical treatment air and warning system adopts the object management module of plug-in type, chooses corresponding administration module, make management have more specific aim according to the feature of monitored object.
Supervisory system provides unified monitoring management platform, and platform easily realizes the installation of all kinds of management plug-in unit, thus obtains all kinds of relevant information of application resource and by powerful ServiceReporter, help user's Timeliness coverage problem, deal with problems.
The present invention uses B/S interactive mode, and complete Chinese operation interface and system management, the logic sum of running background complexity arranges task, and user only needs open any browser just can check the running status of medical air monitoring system and be configured.System software has the graphical tools of Centralized Monitoring, is applicable to the needs of distributed monitoring centralized management, provides detailed data record and alarm record.
The software section of medical treatment air monitoring system is primarily of a few part composition below:
