Registering instrument is regulated to be a kind of multi-functional adjustment registering instrument adopting 128 × 64 dot matrix single colour liquid crystal displays of 8-bit microprocessor and high brightness LED backlight.Regulate that registering instrument can gather, preserves, the significant data analyzed in various industrial process, be applicable to the unity loop control of the temperature of middle-size and small-size process unit, pressure, flow and other parameter.Register control is commonly called as " valve positioner ", pneumatic positioner valve, electropneumatic valve positioner and intelligent valve positioner is divided by structure, it is the main accessories of variable valve, usual and pneumatic control valve supports the use, it accepts the output signal of regulator, then goes to control pneumatic control valve, when after variable valve action with its output signal, the displacement of valve rod feeds back to valve positioner by mechanical hook-up again, and valve position situation passes to Upper system by electric signal.Each oxygen tank valve has two, is air intake valve and valve of giving vent to anger respectively.Alarming value has upper and lower bound to distinguish, and in time reaching lower limit, closes valve of giving vent to anger.In time reaching higher limit, close air intake valve.Valve switch condition judgment and control are all carried out on intelligent terminal.Client long-range transmission instruction can operate control.
Described intelligent terminal is provided with VGA display screen and is convenient to onsite user's real time inspection oxygen tank volume, pressure and valve switch status information.Be provided with short message alarm module in described intelligent terminal, when oxygen tank volume, pressure reach alarming value, short message alarm module sends the alarm mobile phone number that alarming short message is given directions to client.Described intelligent terminal be provided with for the RS232 interface of external alarm linkage equipment, RS485 interface, USB interface or.Intelligent terminal leaves the common interfaces such as RS232 interface, RS485 interface, USB interface and RJ45 interface, and can carry out interlock with external equipment when reporting to the police and starting and complete other function, extendability is very abundant.
The intelligent terminal of native system adopts 3G intelligent wireless terminal.Intelligent terminal software uses Microsoft Windows Mobile platform to offer meter, ripe and be stablely convenient to secondary development and customized development.The core part of intelligent terminal is supervisory system and DTU module.Supervisory system on intelligent terminal can meet the particular/special requirement of some special industry to frequency acquisition and acquisition precision.The effect of supervisory system is the packet of resolving DTU module reception, carries out task assign according to packet content.And subordinate equipment is returned next data analysis and packing, if the image data returned exceedes preset alarm value start SMS alarm function, and send to DTU module after data packing, by DTU module, packet is finally passed back middleware server.DTU module and data transmission unit DTU are specifically designed to serial data to be converted to IP data or IP data to be converted to the wireless terminal device that serial data undertakies by cordless communication network transmitting.DTU module is the M2M module of a technical grade, embedded PPP, ICP/IP protocol stack supports to support the APN private network DSC addressing mode of mobile operator to support fixed ip address and domain name to support TCP/UDP/ note three kinds of communication mode TCP/UDP links to support by RTU and DSC transparent data transfer, and the heartbeat function TCP/UDP link heavy link time configurable support free time rolls off the production line and timed and forced offline mode, support that the support of automatic wire charging mode of operation wakes mode of operation of reaching the standard grade up, note can be passed through, phone, RTU data three kinds of modes are waken up and are supported that serial ports exports the serial port baud rate of Debugging message support the highest 115200. and in the utility model, DTU module will embed intelligent terminal, complete the function of wireless data transceiving.
Under normal circumstances, the intelligent terminal of each website timing can send " heartbeat " bag to middleware server, and whether each website intelligent terminal communication is normal to be convenient to allow middleware system know.When there is network interruption, judge whether communication is interrupted according to the timing unit that " heartbeat " wraps; When judging intelligent terminal fault, can be according to " heartbeat " bag whether return on time and return data packet format whether effectively normal, just can inform each website real time status of client of application server in time, be convenient to user and do next step and arrange.
See Fig. 2, the monitoring flow process of native system is as follows:
1. first, the client of client logs application server, assigns instruction to client.Client by ICP/IP protocol command to middleware system.
2. run on the middleware system of middleware server, after receiving the order that application server client assigns, by associated communication protocol rule, packing operation is carried out to instruction, utilize the fixed time interval being arranged on the USB interface 3G transceiver on middleware server and arranging in application server client by user, self-timing sends request packet in turn to the intelligent terminal of each oxygen website.Packet content contains oxygen station dot address (as: the first oxygen website 01, second oxygen website 02), (such as 3 read function code, 4 writes), data address (pressure 0001, volume 0003, valve switch amount information 0005), cyclic redundancy check (CRC) code).
3. the intelligent terminal of each oxygen website is after receiving request data package, carry out School Affairs to packet to unpack, then according to the request content receiving packet, read or write operation is carried out to adjustment registering instrument, and then regulate registering instrument Real-time Collection to pressure and volume data return to intelligent terminal, intelligent terminal judges return data according to the alarming value pre-set and alarm mobile phone number, judge whether oxygen tank current pressure and volume reach preset alarm value, if reach alarming value just send alarming short message to alarm mobile phone number, alarming value and alarm mobile phone number can (SMS alarm function can arrange by client is long-range the phone number receiving SMS alarm by the long-range setting of client of application server, sending node and frequency).Because intelligent terminal leaves RS232.RS485 and USB interface can external miscellaneous equipments, can carry out interlock complete other function when reporting to the police and starting with external equipment.If containing valve switch amount information in request data package, intelligent terminal is just to register control transmit button electric signal, and register control drives the Push And Release of oxygen tank valve according to switched electrical signal.And the operation signal returning success or not is to intelligent terminal; After putting at intelligent terminal the operation signal regulating the data that return of registering instrument and register control to return in order, carry out packing encapsulation of data by packet rule, by the 3G transceiver module of intelligent terminal, packet is returned to middleware server by 3G wireless network.
4. the middleware system of middleware server is after receiving the packet that each oxygen website returns, by middleware system, School Affairs parsing is carried out to data, confirm that whether packet is effectively complete, if packet occurs that not in valid format or data exception can predicate oxygen website field apparatus and break down for a long time, and the related data information after parsing, as site name, pressure, volume, operation flag, valve state, in the Database Systems of the information write middleware servers such as time, the client being convenient to application server uses.Now, the oxygen tank that the Database Systems of middleware server have each oxygen website in real time and historical data, user can select PC computer, smart mobile phone or IPAD panel computer, the Web Service being called application server by corresponding client is visited and operates the database of middleware server and assigns dependent instruction.
