Description

MEASURING DATA COLLECTION SYSTEM AND METHOD THEREOF {A SYSTEM FOR COLLECTING MEASURED DATA AND METHOD THEREOF}

The present invention relates to a system and a method for collecting and managing data measured by a measuring instrument, and more particularly, to standardize different measuring communication protocols, and to measure the data measured by the plurality of measuring instruments to various inspectors and PCs (users). Measurement data collection system and its method to greatly increase the efficiency of inspection work and to easily collect and manage measurement data by forming a N: N sharing relationship between users and instruments to transmit in real time. It is about.

As is well known, a measuring instrument is usually installed in a manufacturing line or the like to perform various inspections on a product, for example, an oscilloscope or a tester.

In the accompanying drawings, Figure 1 shows a data acquisition system via a conventional instrument.

However, such a data acquisition system is a method of collecting measurement data by connecting a plurality of instruments 10 with a single PC 20 to the RS-232 communication port built in the PC 20. In the case of performing an inspection on one item through the measuring instrument 10, even if the other measuring instrument 10 is not in use, the other measuring instrument can be used only after the measurement of all the inspections on the items performed by the PC user is completed. .

Therefore, this leads to a problem of long inspection time, bottleneck of inspection work, and consequently increase inspection cost.

The present invention has been made to solve the above problems, and an object of the present invention is to standardize different communication protocols of instruments, and to transmit data measured through a plurality of instruments to various inspectors and PCs (users) in real time. By providing an N: N sharing relationship between the user and the instrument, it is possible to provide a measurement data collection system and a method for greatly increasing the efficiency of inspection work and easily collecting and managing measurement data.

Automatically generating (numbers or letters) (S30) and the generated ID (data) is a PC real-time control server 300 in a TCP / IP communication method (T3) via a LAN line connected to each PC 400 If the step (S40) and the ID generated and transmitted from the PC 400 is input to the PC real-time control server 300, the PC real-time system The server 300 transmits the unique ID data only to the corresponding CPIM 200, which is already set through the address setting unit 240, through the RS-485 communication (T2) (S50) and the measuring instrument 100. Initiating and completing the measurement through the step (S60), and when the inspection of the measuring instrument 100 by the inspector is completed, the measured data is transmitted to the CPIM 200 by RS-232 communication (T1), and processed into real data. Step (S70) displayed on the display unit 230 and the examiner key-in the data transfer switch 213 of the key input unit 250 of the CPIM 200, the ID and the measurement data is RS-485 communication ( T2) step (S80) is transmitted to the PC real-time control server 300, and the PC real-time control server 300 received the ID and the measurement data is the PC that issued (generated) the first ID and the measurement data Step (S90) and transmitting to the 400, the PC 400 received the ID and measurement data from the PC real-time control server 300 is measured The emitter comprises a storage (acquisition) and the step of managing (S100).

The operation of the present invention configured as described above will be described with reference to the flowchart of FIG.

First, in order to collect measurement data through the instrument 100, the PC real-time data server 300 is a predetermined communication setting to the CPIM 200 connected to each instrument 100 in the RS-485 communication method (T2) The condition, that is, baud rate, parity, data bit, stop bit, and start and end position of the instrument collected data is transmitted (step S10).

In this case, the communication setting condition is to transmit the RS-232 communication condition to the CPIM 200 so that the RS-232 communication (T1) is made between the CPIM 200 and the meter 100.

Accordingly, the signal is input to the controller 230 through the input / output unit 250 of the CPIM 200, and the controller 230 input / output condition according to the RS-232 communication method (T1) through the input communication setting condition. Will be set.

As such, when the CPIM 200 connected to each of the measuring instruments 100 is set, the user selects (designates) an inspection item to be measured using each PC 400, that is, the measuring instrument 100 (S20).

In this case, if the measurement device 100 is designated, the PC 400 automatically generates a unique ID (number or letter) according to the corresponding operation (step S30).

The generated ID (data) is transmitted to the PC real-time control server 300 in a TCP / IP communication method T3 through a LAN line connected to each PC 400 (step S40).

When the ID generated and transmitted from the PC 400 is input to the PC real-time control server 300, the PC real-time control server 300 has already set the unique ID data through the RS-485 communication (T2). It transmits only to the corresponding CPIM 200 set through 240 (step S50).

In this case, the transmitted ID is displayed on the display unit 220 of the CPIM 200.

Under such conditions, when the inspection of the measuring instrument 100 by the inspector is completed, the measured data is transmitted to the CPIM 200 through RS-232 communication (T1), and the input / output unit 250 of the CPIM 200 is transferred. Measurement data of the RS-232 communication (T1) input through the processed via the control unit 230 is displayed on the display unit 230 (step S70).

When the inspector checks the measurement data through the display unit 220 of the CPIM 200 and then inputs the data transfer switch 213 of the key input unit 250, the ID and the measurement data are inputted through the input / output unit 250. RS-485 communication (T2) is transmitted to the PC real-time control server 300 (step S80).

PC real-time control server 300 receives the ID and the measurement data is transmitted to the PC 400 that issued (generated) the ID and the measurement data (step S90).

The PC 400 receiving the ID and the measurement data from the PC real-time control server 300 stores (collects) and manages the measurement data (step S100).

As described above, the present invention standardizes different communication protocols of instruments, and transmits data measured at the current measuring equipment to various inspectors and PCs in real time, so that the instruments can be shared in an N: N relationship between the measuring instrument and the user. Each inspector can select the measuring equipment to measure the inspection items regardless of the order of the inspection items to be inspected.

Therefore, there is no bottleneck in the inspection work, and it is a useful invention that the inspection cost is lowered.
