Description
Technical field
The present invention relates to a kind of proving installation and method of electronic installation, particularly a kind of proving installation of output/input interface of electronic installation and method.
Background technology
On-the-spot real time information system (Shop Floor Information System is hereinafter to be referred as SFIS) has been used in many manufacturing industry.SFIS and extends to real-time production information service to the client gradually except can monitoring the production scene.The client can be by the Internet (internet) and client's that the supplier offers customer number (user ID) and password (password), and sees the production real-time information that the supplier provides from computer screen.The characteristics of SFIS comprise:
(1) can satisfy the requirement of client's punctual delivery
SFIS can follow the trail of according to client's specific demand and part material table at finished product or part stage.In addition, also can provide production management unit's optimal scheduling resource, testing apparatus and transport flow process.In addition, the client also can accurately grasp the time of receiving.
(2) change the production management mode in the production
SFIS can collect complete production process information in process of production, and whether tracing product is made according to requirement specification, provides real-time production process to improve and product quality tracing and improvement in the future.
Because on-the-spot real time information system has can satisfy client's punctual delivery, change advantages such as production management mode and minimizing stock aborning, therefore on-the-spot real time information system is applied in all types of industries gradually.With the computer main frame panel is example, import the SFIS system and will in database, set up the relevant information of a correspondence each motherboard, caing be compared to is that each finished product has had I.D. separately, thereby has very great help for the foundation of output, product quality keyholed back plate and stock or the like information.
In addition, motherboard disposes various electronic components and connecting interface, and whether connection status to each other will have influence on motherboard can operate as normal.In order to confirm the welding situation of each tie point between electronic package gang socket and the motherboard, usually to test the assembly on the motherboard (for example input/output port or the like), so as to confirming whether tie point has defectives such as cold welding or empty weldering, to avoid occurring bad product.With the input/output port is example, has comprised serial port etc.Serial port refers to the equipment that is used for doing communication terminal in the computer system, and it can carry out with the position is the transmission of unit, is used for connecting modulator-demodular unit or early stage mouse.At least all there are two serial ports to use in the computer system for us, our PORT COM COM1, COM2 of often saying just, these two serial ports are commonly used to connect mouse and modulator-demodular unit.The pin of serial port (Pin) has two kinds of patterns, and a kind of is 9 pins, and another kind then is 25 pins.What mouse was used usually is 9 pins, and modulator-demodular unit then is 25 pins.These two kinds of pins are the same in fact, and the mode that can see through wire jumper between them change, as on earth will be that a kind of pin, do not have certain rule, depend on the circumstances, if the equipment that uses is 9 pins, with regard to joint with 9 pins.Each pin of PORT COM (9Pin) is defined as follows:
Pin 1: data medium detects (DCD-Data Carrier Detect)
Pin 2: receive data-signal (RXD-Recive Data)
Pin 3: data signal (TXD-Transmit Data)

For the PORT COM on the motherboard, if PORT COM is used as SFIS system transmissions data, then PORT COM only can be used the TXD and the RXD signal pin of PORT COM when transmission.In other words, in the process of PORT COM, the SFIS system can only test TXD and RXD signal pin, and other signal DCD, TXD, DTR, DSR, RTS, CTS, RI are not had actual test on the Test Host plate, therefore will increase the test leakage risk.
Certainly, the tester can also use existing testing tool to test PORT COM.The general test instrument is to use regression test (loop back test) technology to test PORT COM.So, comprise that DCD, TXD, DTR, DSR, RTS, CTS, RI can intactly testedly arrive.Since when carrying out regression test, be necessary for short circuit between TXD and the RXD, in the time of still will utilizing the information of SFIS system transmissions motherboard, then can not short circuit between TXD and the RXD.Therefore, factory in process of production need be by the operating personnel in artificial mode from the connecting line of the PORT COM of motherboard plug testing tool or the connecting line of SFIS, transmit this two tests to finish regression test and SFIS.The operational motion that operator will carry out can be divided into following several steps:
(1) previous operations: the PORT COM that the SFIS system is connected motherboard to be measured from (Auto Link) test transmission line that is dynamically connected.
(2) carry out the PORT COM regression test: the PORT COM from motherboard to be measured is pulled up the Auto Link of SFIS system test transmission line, connects the regression tested testing tool again.Press "enter" key" at motherboard platform to be measured then and continue test.
(3) after the PORT COM regression test, pull up the regression tested testing tool from the PORT COM of motherboard to be measured, turn back to the Auto Link of SFIS system test transmission line then, and press "enter" key" at motherboard platform to be measured and continue test.
From the above, if want PORT COM is carried out test operation and SFIS system transmissions, existing operating process need be taked manual type plug testing tool and SFIS transmission line.Yet, the like this practice not only consuming time and artificial careless mistake of easy generation on the one hand, on the other hand, frequent Plug Action also makes assembly such as testing tool shorten serviceable life because of consume easily.
