Relates to a device.

In general, a device that converts analog inputs of process variables such as temperature, flow rate, pressure, load, and length into digital numbers and automatically records them is called a data logger.

The data history recorder installs a measuring sensor of load / pressure / length in the tester, and converts the electric signal that is sensed as the load / pressure / length received by the specimen during the test into a digital signal through the AD converter. Measurements are shown on sheets and diagrams instructed by the user at regular time intervals on the typewriter.

In addition, if the user exceeds the limit of the preset measurement value, it is printed with a deficit or expressed with an alarm sound so as to control the damage of the equipment in use and the limit of the test purpose.

The main body of the data history recorder is configured to perform a user's input of a program capable of arithmetic between the variable names by naming the measured information.

In addition, since it is already set as necessary during the test and the storage cycle can be arbitrarily changed according to the judgment of use, unnecessary data input can be reduced.

In addition, in the case of continuous tests, there is a pause function that temporarily stops saving data while preparing for the next step test, reducing the need to restart from the beginning.

In this case, it may be distinguished as a computerized automatic history recorder.Measurement in an industrial plant is a method of intensively monitoring by installing a plurality of instruments on a panel of a management room. It is replaced by an automatic typewriter, making it easier to monitor.

However, existing products are equipped with a format that records measurement values as it is, for each device.In contrast to the intention of the device user, the device maker has software that operates only a very simple program that ignores the intention of the user and the performance of the device. Because there is too much unnecessary data or cannot obtain the data necessary for the test purpose, and because the program is operated for each device only, the cost of each program must be paid for each device, not just the cost of the device. In terms of its disadvantages, there was a disadvantage.

The present invention was created in order to solve the conventional problems as described above, consisting of 16 channels of analog sensor and 16 channels of digital sensor, a total of 32 channels to measure and transmit the load / pressure / length at the same time, the measurement value to the operating computer Using a program that can be operated on measuring instruments by comparing the actual values obtained in real-time with transmissions and predetermined variables, and allowing the tester to directly input and change numerical values or calculation formulas according to the amount of change. It is an object of the present invention to provide a general-purpose data history recording device that can measure data and display data in a graphic manner while simultaneously measuring data.

Consists of

The power supply may use any one of a battery, an AC power source, and a solar cell.

The transceiver is applicable to wired communication and wireless communication.

The operating computer may perform various calculations and analyzes with the measurement data transmitted by the transmitting unit, and input a basic numerical value (reference value) before measurement to determine the amount of change by comparison.

That is, the user receives the value measured by the sensor, but the user can set the period of the input time, and can set the calculation formula for the information to be obtained by using the input measured value and the variable known in advance.
