(9) detection of switching value signal and circuit.
Carry out hardware design according to the function that will realize, blueprint drawing and shell manuscript are assembled then, are debugged, as shown in Figure 8.
(1) three input/output test parameter channel detection module embodiment.
To consider during the design hardware circuit to change original measurement circuit, can not influence the accuracy of original test data, leave insertable measurement point to measurement again.Therefore design an input interface and an output interface, the identical and connection one by one of contact definition can not influence the connection of indoor and outdoor cable, and panel should have the test port of respective points simultaneously, has designed three drive tests examination passage altogether, and circuit diagram is seen Fig. 1.As shown in Figure 8, when measurement circuit breaks down, only need original closed test circuit is disconnected from the connector junction, receive any one tunnel (input and output connector of front and back panel) of the three drive tests examination passage of test macro self diagnosis instrument respectively, such as input 1 and output 1, so just the binding post of the respective channel of plate is measured each core of measurement circuit with multimeter in the above, can online detection encourage power supply, sensor output signal, thereby can the failure judgement reason.
(2) analog sensor detection module embodiment.
For to carry out the screening of passage, designing a sensor simulator unit under the condition of no sensor, mainly is simulation full-bridge type electric resistance sensor, three resistance are fixed in four brachium pontis, another is an adjustable resistance, comes the physical quantity of analog sensor to change by regulating this resistance, and circuit diagram is seen Fig. 2.As shown in Figure 8, when system's detection or channel screen, the passage to be measured of test macro is received on the analog sensor connector of test macro self diagnosis instrument front panel, the zero balance situation and the signal situation of change of test macro can be detected by regulating adjustable potentiometer, thereby the availability of this test channel can be judged.
(3) demarcate indoor, outdoor line detection module embodiment.
For detecting sensor is demarcated circuit, designed transducer calibration indoor and outdoor inspection of line circuit according to actual operating position, circuit diagram is seen Fig. 3, wherein switch is for demarcating button, be used to send demarcation signal, press the demarcation button and show that demarcating point value adds, the triggering collection system gathers this value; Bulb is the calibration value collection pilot lamp that finishes, and the calibration value that is used to notify the proving operation personnel to load has been gathered and finished, and can load next and demarcate point value.Outdoor circuit check circuit can be demarcated circuit and demarcates box and carry out open detection stage body.As Fig. 3, shown in Figure 8, break down when maybe needing to detect when demarcating circuit, circuit in the inspection chamber at first, test macro is demarcated the demarcation that control line is linked into test macro self diagnosis instrument front panel to be detected on the connector, test macro operation calibrating procedure is pressed the demarcation button on the top panel, carries out signals collecting and demonstration if test macro receives this trigger pip, the demarcation pilot lamp of top panel is bright afterwards, and this situation shows that the indoor standardization circuit is normal; The outer calibration line road of inspection chamber then, the cable of outdoor demarcation circuit is received on input 4 connectors of test macro self diagnosis instrument rear panel, five binding posts by the top panel respective channel can measure with multimeter whether outside to demarcate circuit normal, usually when the other end closure calibration switch of outdoor demarcation circuit, can measure between 1,2 and lead to, otherwise disconnect, the ohmmeter open-wire line road that can measure twenties ohm between 4,5 is normal.
(4) test macro relay board and line detection module embodiment.
Data acquisition system (DAS) is not only finished the collection of data, also to carry out control simultaneously to external unit, the control of external unit mainly realizes by the relay board of system, design the relevant detection circuit for detecting relay board and measurement circuit, circuit diagram is seen Fig. 4, two bulbs are respectively normally closed contact indication and normally opened contact indication, 1,2 normally closed contacts of succeeding electrical equipment in seven core connectors, 1,3 normally opened contacts of succeeding electrical equipment among the figure.For judging or detect the quality of test macro operation circuit and control function plate-relay board, as shown in Figure 8, the relay that the control signal of test macro relay board output can be linked into test macro self diagnosis instrument front panel detects on the connector, also the power supply access connector of direct voltage source from the front panel of test macro self diagnosis instrument should be inserted simultaneously, adhesive and disconnection by the system program pilot relay, under the normal condition, if relay adhesive, then the normally opened contact pilot lamp of top panel is bright, normally closed contact goes out, whether if relay disconnects then be opposite, it is normal so just can to judge relay board output control signal and operation circuit.
(5) outside wire road detection module embodiment in the switching value signal cabin.
Data acquisition system (DAS) is except gathering simulating signal, also to gather such as jet pipe jam signal some switching value signal, be different from collection of simulant signal on the acquisition mode, answer the circuit of design specialized in switching value signal and wireline inspection thereof for this reason, circuit diagram is seen Fig. 5,1 of seven core connectors, 3 and 2,4 insert double switch amount signal respectively shown in the indoor test section among the figure, simulate jet pipe jam signal with two switches respectively in this circuit.The outer circuit check circuit of switching value signal cabin can carry out open detection to outdoor circuit binary channels.As Fig. 5, shown in Figure 8, the jam that during indoor wireline inspection test macro switching value measurement circuit is linked into the front panel of test macro self diagnosis instrument detects on the connector, two buttons of the jam sense channel by test macro self diagnosis instrument top panel come analog switch amount signal, under the normal condition, by these two buttons, test macro can demonstrate the variation of switching value signal respectively; When circuit detects outside to respective compartments, outdoor switch measurement amount circuit to be linked on output 5 connectors of test macro self diagnosis instrument rear panel, can measure the connection situation of outdoor circuit by five binding posts of its top panel, if circuit is talked about normally, 1,3 and 2,4 at the outdoor circuit other end are carried out on off test respectively, and the signal of measuring the binding post of corresponding measuring point also should have identical break-make to change.
(6) because the partial circuit in this test macro self diagnosis instrument needs externally fed, thus specialized designs power access circuit, be mainly used in the detection of system relay plate and circuit thereof, circuit diagram is seen Fig. 6.
(7) behind design and the debugging above-mentioned functions circuit, needing design and processing collection above-mentioned functions is the shell of the test macro self diagnosis instrument of one, test macro self diagnosis instrument outside drawing is seen Fig. 7, wherein front panel and rear panel are installed seven core connectors respectively, be used to connect the input and output circuit, top panel comprises binding post that the needs of every test function install, button, pilot lamp, adjustable potentiometer etc., and five binding posts on each road connect one to one with corresponding input and output connector respectively.
