Accompanying drawing explanation
Fig. 1 is JYJC monitoring means cpu motherboard method of testing theory diagram of the present invention.
Embodiment
Whether the peripheral components quality that the present invention is mainly used in testing JYJC monitoring means cpu motherboard is qualified, with reference to shown in accompanying drawing 1, the peripheral components of this monitoring means cpu motherboard comprises RS485 communication interface, RS232 communication interface, output relay, output lamp plate and input key.Followingly for the method for testing of testing JYJC II type monitoring means cpu motherboard, the preferred embodiments of the present invention to be described, to should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
The method of testing of JYJC II type monitoring means cpu motherboard of the present invention, adopts the peripheral components of two kinds of single-chip microcomputers to JYJC II type monitoring means cpu motherboard to carry out quality testing, and is shown test results by the display device that this monitoring means cpu motherboard itself drives.
First single-chip microcomputer is STC15W204S single-chip microcomputer, and the RS485 communication interface of this STC15W204S single-chip microcomputer and JYJC II type monitoring means cpu motherboard is connected to form communication single chip circuit.Because JYJC II type monitoring means cpu motherboard has 6 RS485 communication interfaces, therefore according to actual testing requirement, above-mentioned 6 RS485 communication interfaces can connect 6 STC15W204S single-chip microcomputers respectively, form six communication single chip circuits.The mode of operation of this communication single chip circuit is: JYJC II type monitoring means cpu motherboard initiatively sends to the instruction of STC15W204S microcontroller communication by RS485 communication interface, STC15W204S single-chip microcomputer makes corresponding reply after receiving instruction, the reply data that whether normally can receive STC15W204S single-chip microcomputer according to JYJC II type monitoring means cpu motherboard judge, if this monitoring means cpu motherboard can receive reply data, judge that this RS485 communication interface is up-to-standard, if reply data can not be received, judge that this RS485 communication interface is off quality, thus the test realized the RS485 communication interface of JYJC II type monitoring means cpu motherboard.
Second singlechip is STC12C5A60S2 single-chip microcomputer, and the RS232 communication interface of this STC12C5A60S2 single-chip microcomputer and JYJC II type monitoring means cpu motherboard, output relay, output lamp plate, input key are connected, and forms master singlechip circuit.This master singlechip circuit comprises two kinds of mode of operations:
The first mode of operation is: change output relay by JYJC II type monitoring means cpu motherboard, export the state of lamp plate interface, namely arranging I/O interface is 0, and the STC12C5A60S2 single-chip microcomputer this state sent to by RS232 communication interface in master singlechip circuit, STC12C5A60S2 single-chip microcomputer direct-detection output relay simultaneously, export the Interface status of lamp plate, then the data that direct-detection data and RS232 communication interface transmit compare by STC12C5A60S2 single-chip microcomputer, and comparative result is returned to JYJC II type monitoring means cpu motherboard by RS232 communication interface, JYJC II type monitoring means cpu motherboard changes output relay, exports lamp plate Interface status afterwards, and namely arranging I/O interface is 1, the samely carries out a communication again, judges, compares and return,
JYJC II type monitoring means cpu motherboard makes analysis to twice comparative result, whether qualified: if twice comparative result all shows the data consistent that STC12C5A60S2 single-chip microcomputer direct-detection data transmit with RS232 communication interface, judge that output relay is qualified with the interface capability of output lamp plate if drawing output relay and exporting the interface capability of lamp plate; If it is inconsistent that twice test result all shows the data that STC12C5A60S2 single-chip microcomputer direct-detection data and RS232 communication interface transmit, judge output relay and export the interface capability of lamp plate defective; If only have the data consistent that a kind of comparative result of state display STC12C5A60S2 single-chip microcomputer direct-detection data and RS232 communication interface transmit, it is qualified to judge output relay under this corresponding states and export the interface capability of lamp plate, and output relay under another kind of state and to export the interface capability of lamp plate defective.
The second mode of operation is contrary with the first mode of operation, the state of input key interface is changed by STC12C5A60S2 single-chip microcomputer, namely arranging I/O interface is 0, and this state is sent to JYJC II type monitoring means cpu motherboard by RS232 communication interface, the Interface status of JYJC II type monitoring means cpu motherboard direct-detection input key simultaneously, then the data that direct-detection data and RS232 transmit compare by JYJC II type monitoring means cpu motherboard;
STC12C5A60S2 single-chip microcomputer changes the Interface status of input key afterwards, namely arranging I/O interface is 1, the samely carry out a communication again, judge and compare, JYJC II type monitoring means cpu motherboard makes analysis to twice comparative result, show that whether the interface capability of input key is qualified: if twice test result all shows the data consistent that JYJC II type monitoring means cpu motherboard direct-detection data and RS232 communication interface transmit, judge that the interface capability of input key is qualified; If it is inconsistent that twice test result all shows the data that JYJC II type monitoring means cpu motherboard direct-detection data and RS232 communication interface transmit, judge that the interface capability of input key is defective; If only have the data consistent that a kind of test result of state display JYJC II type monitoring means cpu motherboard direct-detection data and RS232 communication interface transmit, judge that the interface capability of input key is qualified under corresponding states, and the interface capability of input key under another kind of state is defective.
While second singlechip detects output relay, output lamp plate or input key interface capability, the transmission data of second singlechip can be received according to JYJC II type monitoring means cpu motherboard, can judge that whether the quality of RS232 communication interface is qualified.If JYJC II type monitoring means cpu motherboard can receive the transmission data of STC12C5A60S2 single-chip microcomputer, judge that RS232 communication interface is up-to-standard; If the transmission data of this STC12C5A60S2 single-chip microcomputer can not be received, judge that RS232 communication interface is off quality.
All test results that in the present invention, JYJC II type monitoring means cpu motherboard obtains all can be presented in connected LCD liquid crystal display screen in real time, the state of being tested by word and auditory tone cues and result.In addition, two kinds of single-chip microcomputers of the present invention arranged or is connected with the pilot lamp being used to indicate corresponding component quality accordingly, being beneficial to more intuitively pinpoint the problems timely.
Because above-mentioned method of testing does not all need manual operation, only need watch display screen or pilot lamp, possess in this approach intellectuality, robotization, simply, feature easily and efficiently.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in previous embodiment, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
