Further, described processor is also connected with an alarm B for pointing out test result.Described power module is powered for all the other modules, it comprises power supply and power switch, the direct connection handling device of power supply, sampling module, valve, alarm A, alarm B and display, power supply connects tested mainboard by power switch, and power switch is also connected with processor.Detection system also comprises a current detection circuit, and described current detection circuit is connected between power switch and tested mainboard, and for reading working current and the static working current of tested mainboard, the output terminal of current detection circuit is connected with processor.After tested mainboard is connected to frock by fixture; operating personnel press " beginning test button "; processor is tested main board power supply by controlling power module; current detection circuit reads working current and the static working current (working current namely in loop and quiescent current) of tested mainboard; and current data is transferred to processor; processor judges whether current data exception occurs; if occur abnormal, control power switch and disconnect rapidly; cut off the power supply supply of tested mainboard, do not burnt with protecting tool set-up itself and tested mainboard.
Further, described alarm A comprises one or both the combination in hummer or pilot lamp, and alarm B comprises one or both the combination in hummer or pilot lamp.
The invention has the beneficial effects as follows:
1, a kind of mainboard detection system of the robotization based on processor is proposed, this system is by the circuit structure of appropriate design, Aulomatizeted Detect is carried out to the various functions of gas meter, flow meter mainboard and electric parameter, to greatly reduce in testing process artificial demand and automatically can preserve testing result, and drastically increase detection speed and accuracy of detection, stop artificial erroneous judgement and failed to judge;
2, testing result can not only be shown over the display and check for operating personnel, also by simple and clear the pointing out testing result of mode of hummer or pilot lamp, facilitate testing staff to operate.
Accompanying drawing explanation
Fig. 1 is detection system structural representation of the present invention.
Embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing, but the content that the present invention protects is not limited to the following stated.
As shown in Figure 1, Intelligent Card for Gas Meter mainboard automated detection system, comprise processor, power module, tested mainboard, sampling module, valve, IC-card, alarm A and display, processor is connected with display with power module, sampling module, valve, IC-card, alarm A respectively, and sampling module, valve, IC-card are connected with tested mainboard respectively with alarm A.IC-card is used for supplementing with money for tested mainboard; sampling module is for checking sampling and the defencive function of tested mainboard; whether valve and alarm A correctly perform dependent instruction for detecting tested mainboard; all testing results are all transferred in processor carries out preserving and processing, and the testing result received is shown by display by processor.
