The utility model provides a kind of civilian intelligent gas meter complete machine function detecting method, is operated first personnel according to intelligence The detection demand of IC card gas meter, flow meter complete machine 5, by human-computer interaction interface 11 in the flow control unit 1 input model and Testing process number, the information that the first controller 12 is obtained according to human-computer interaction interface 11 in flow control unit 1 is from flow and ginseng Testing process and parameter are extracted in number memory 13, detection is carried out and prepares；After flow control unit 1 carries out detection preparation, Intelligent Card for Gas Meter complete machine 5 is positioned over assembly line designated position by operating personnel, and the insertion gas meter, flow meter of analog interface card 3 is whole Then the IC card deck of machine sends out startup detection signal, the first controller by human-computer interaction interface 11 to the first controller 12 12 receive start detect signal after i.e. start to second controller 21 transmission testing process in first detection.
The paper process needed under traditional artificial detection mode and tool IC card digitization are stored in stream by this control system Process control unit 1, operating personnel only need to transfer corresponding testing process according to gas meter, flow meter model to be checked, simplify production Process management, reduces the probability of happening of maloperation, and preparation when isochrone production interchange also greatly simplifies, and makes entirely to examine Efficiency is surveyed to be significantly improved.
The specific testing process of the utility model is as follows：
One：Detection starts
First detection of different model gas meter, flow meter detection is detection enabled instruction, this instruction is required intellective IC card Gas meter, flow meter complete machine 5 is sent into detection device station from assembly line, clips fastening by tong-test ammeter mouth, while simulated battery head being sent into and is fired Gas meter complete machine battery compartment.The parameter of instruction is current gas meter, flow meter to be checked Card Type, battery compartment height.Second control Device 21 parses this instruction after receiving this instruction, obtain starting detecting operation code and current gas table complete machine Card Type, Battery compartment height is simultaneously kept in.Then control signal is sent out to valve drive module 23 according to operation code, this signal passes through valve It is opened in drive module 23 and the channel control of table cylinder solenoid valve is sent to send table cylinder that Intelligent Card for Gas Meter complete machine 5 is pushed into detection Equipment station, then second controller 21 send out control signal to valve drive module 23 again, this signal is driven by valve In module 23 open tong-test ammeter cylinder solenoid valve channel control tong-test ammeter cylinder by Intelligent Card for Gas Meter complete machine 5 in detection station Clip fastening.Following second controller 21 to servo control module 24 send out current gas table complete machine battery compartment height parameter and Signal is controlled, control servomotor 441 drives lead screw slide unit 442 to move to phase after servo control module 24 receives parameter and signal The height answered.Then second controller 21 sends out control signal to valve drive module 23, this signal is driven by valve first Simulated battery head is pushed forward into gas meter, flow meter by the channel control battery advance and retreat cylinder that battery advance and retreat cylinder solenoid valve is opened in module 23 Then complete machine battery compartment controls battery or so gas by opening the channel of battery left and right cylinder solenoid valve in valve drive module 23 Cylinder makes simulated battery head well be contacted with electrode reed in gas meter, flow meter complete machine battery compartment.To make Intelligent Card for Gas Meter complete machine 5 In state to be checked, completion starts all over detection instruction.The mechanical action of each of the above cylinder is by sensor module 41 Cylinder location sensor group 411 generates feedback signal input pickup input module 22, and second controller 21 can pass through these letters Number judge whether the action of cylinder is completed.If centre has the action of any one cylinder to be not successfully completed, second controller 21 is The transmission for stopping subsequent instructions, to avoid mechanical interferences and collision, the damage for preventing detection device and having in inspection table.Simultaneously to the One controller 12 sends instruction execution and unsuccessfully feeds back.First controller 12 stops sending remaining detection after receiving unsuccessfully feedback The detection instruction of item, and prompt is sent out to operating personnel by human-computer interaction interface 11.
In detecting starting step, this system controls each mechanical action by output drive signal under program control Mechanism will originally need manual operation complete table tool transfer, arranging batteries, table tool fasten etc. actions be automatically performed successively.It reduces Manually-operated labor intensity.This system program is also supervised by sensor module 41 in real time while output controls signal The location information for controlling each actuating cylinder can interrupt subsequent action if not completing, avoid to judge whether current action is completed Mechanical interferences and collision, prevent failure and damage.
Two：Least unit tolerance writes table
Table testing requirements are write to pass the first controller 12 by IC card with the data transferred in parameter storage 13 from flow It is defeated by Intelligent Card for Gas Meter complete machine 5.Realize that this process first has to write data into the logic encryption card in second controller 2 In chip 25 or CPU card chip 26, then IC card chip is connected to again with gas meter, flow meter deck, realizes off-balancesheet Card Reader.
When testing process item is to write table detection, the first controller 12 will write table handling code and be stored from flow and parameter The data merging transferred in device 13 writes table instruction as one and is sent to second controller 21.The parameter of instruction needs for current procedures The data to be written into gas meter, flow meter.Second controller 21 receive write table instruction after parsed, obtain operation code and Table data are write, the current gas table obtained in enabled instruction is detected in first step according to operation code and second controller 21 Control line is selected to select the analog switching ic 271 in analog switch module 27 to send out to IC card by IC card with Card Type Signal is controlled, the IC card chip currently to be operated is selected, when current gas meter, flow meter complete machine to be checked uses logic encryption card by IC Card data connection bus 272 is connected to logic encryption card data/address bus 251, when current gas meter, flow meter complete machine to be checked uses CPU card When IC card data connection bus 272 is connected to CPU card data/address bus 261.Then second controller 21 is switched by IC card and is controlled Analog switching ic 281 of the line 284 processed into IC card switching analoging switch module 28 sends out control signal, by IC card data Connection bus 272 is connected to IC card read-write bus 282, will to make selected IC card chip be connected to second controller 21 It is written in IC card from the table data of writing parsed in instruction.
