Abstract

PURPOSE:To easily obtain necessary measuring data upon the immediate correspondence to a measuring device on the spot, by arranging a memory chip having inherent measuring information preliminarily stored therein at every sensor and reading the same so as to make a set along with the data of the sensor. CONSTITUTION:A memory chip 2 is arranged corresponding to each sensor 1 and stores the sensor-inherent pieces of information such as the kind, mount position, calibration coefficient, objective value, etc. of the corresponding sensor. A memory chip reading/writing device 3 reads/writes the informations of the chip 2 in a non-contact state. A measuring device 4 has a memory mounted therein and is selectively connected to each sensor to obtain measuring data and, at the same time, reads the information of the chip 2 at a measuring time to perform predetermined operation. By this mechanism, the correspondence of measuring data to the sensor is taken and, further, operational processing relating to necessary physical quantity can be immediately performed on the spot. The measured value at each position is stored in the memory and inputted to a data processor 6 later using an apparatus 5 to perform data processing and the print-out of necessary data.

[Detailed Description of the Invention] [Industrial Application Field] The present invention sets a sensor and a storage element that stores unique information of the sensor as a pair, reads the measurement data and the unique information together, and stores the sensor in a predetermined manner. The present invention relates to a measurement processing system that processes data.

[Conventional technology]

FIG. 3 is a diagram for explaining a conventional example of a measurement processing system, in which 21-1 to 21-n are sensors and 22 is a measuring device.

When measuring many items such as strain, load, displacement, temperature, etc. during construction management of construction and civil engineering, various plants, equipment structures, etc., a typical method is to connect the sensors to the location where the measuring device is located using cables. There is a method in which measurement and recording are performed using a multi-point strain measuring device, a personal computer, etc. If this method is adopted, the cost of laying cables and measuring equipment will be relatively high when data is not collected frequently, resulting in poor investment efficiency. Therefore, in such a case, as shown in Fig. 3, take the porta-pull type static strain measuring device 22 etc. to the locations of the various sensors 21-1 to 21-n that have been installed in advance and measure them one by one. A method is adopted in which the measurement position, strain value, measurement date and time, etc. are recorded on recording paper.

[Problem that the invention seeks to solve]

However, since data is collected infrequently, if an on-site measurement and recording method using a portable measuring device such as the one described above is adopted, each sensor 21-1 to 21-n has its own information and purpose. value cannot be used immediately. Therefore, there is a problem in that in order to obtain the necessary values on site, it is necessary to process the information and purpose specific to the sensor using manual calculations or a calculator.

The present invention solves the above-mentioned problems, and aims to provide a measurement processing system that can immediately connect measuring devices and sensors at the site and easily obtain necessary measurement data. It is something.

[Means for solving problems]

To this end, the measurement processing system of the present invention includes a sensor installed at a measurement location, a storage element attached to the sensor, a data reader that collects measurement data, and a data processing bag that processes the data read by the reader. and storing information regarding the sensor in the storage element;
This method is characterized in that a data reading device reads measurement data from a sensor and also reads information from a storage element.

[Effect]

In the measurement processing system of the present invention, by including the above means, sensor-specific information can be set in the storage element in advance, and by reading this information together with measurement data,
Measurement data and sensors can be correlated and processed without fail. Additionally, since the measurement data and sensor-specific information are read at the same location, data reading errors can be eliminated.

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 1 is a diagram for explaining one embodiment of a measurement processing system according to the present invention. In the figure, 1-1 to l-n are sensors, 2-1 to 2-n are memory chips, 3 is a memory chip reading/writing device, 4 is a measuring device, 5 is a data reading device, and 6 is a data processing device. show.

Before describing the embodiments, first, measurement information specific to the main sensors will be explained. Generally, the directly obtained data is different from the generally required physical quantity, but since the characteristics of sensors are usually linear, the required physical quantity can be obtained by multiplying by a certain coefficient. This is the calibration coefficient.

In addition, target values are included in order to make it possible to understand the condition at the same time as measurement and take necessary measures at an early stage.

In general, when measuring with sensors, only vague data may be accumulated, but it usually indicates whether the load, pressure, temperature, etc. are within allowable values, approaching the limit value, rising (declining), etc. ) is too fast (too slow), etc., and the condition of plants, equipment structures, etc. (for example, whether the load, pressure, temperature, etc. are within allowable values or approaching limit values, etc.) The purpose is to carry out maintenance of parts, members, and structures. The target value is to set a physical quantity suitable for such a purpose. Normally, sensors output some value even when there is no load, so the initial value is
This is necessary when knowing the absolute amount of change from the time of installation.

In addition, the initial value may be set using a state where the load is applied as the initial state.

In addition to the above-mentioned calibration coefficients, target values, and initial values,
A memory chip is installed in which sensor type, setting values, and other sensor-specific measurement information is stored in advance for each sensor, and this information is read in as a set with sensor data. An example of this is explained with reference to Figure 1. do.

n is installed corresponding to each sensor 1-1 to l-n, and has sensor-specific information such as the corresponding sensor type, installation position, calibration coefficient, target value, initial value, measured value, measurement date and time, and installation time. The memory chip reading/writing device 3 stores information.
-n reads/writes information stored in the device without contact.

The measuring device 4 has a built-in memory and selectively connects with each sensor 1-1 to 1-n to obtain measurement data, and at the same time reads information from the memory chips 2-1 to 2-n at the time of the measurement. , which performs predetermined calculations. This allows for correspondence between measurement data and sensors, and furthermore, it is possible to immediately perform arithmetic processing on the necessary physical quantities on the spot. Note that the measured values at each of these positions are stored in a built-in memory, and later inputted to a data processing device 6 using a data reading device 5, where data processing and printing out of necessary data are performed.

Chip 16 indicates a data processing device.

In FIG. 2, sensor terminals 14 installed at a plurality of measurement points and memory chips 15 corresponding to the respective sensors are centrally arranged in a sensor one terminal concentration panel 12. Therefore, with this sensor one terminal centralized board 12, the measuring device 1
3 is sequentially connected to the sensor terminal 14 to read the data of each sensor, and at the same time read the sensor-specific information of the memory chip 15, so that the measuring device 13 can store the data of each sensor, its type, initial value, calibration coefficient, Predetermined calculation processing using target values, set values, etc. is performed and recorded.

Note that the present invention can be modified in various ways and is not limited to the above embodiments.For example, in the above embodiments,
Although the measurement data and information read by the reading means are temporarily stored and input to the data processing means offline for processing, wired or wireless communication is required between the reading means and the first stage of data processor. It may also be connected online via a line.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, for each sensor, its type, initial value, calibration coefficient, target value,
A memory chip is installed that stores sensor-specific measurement information such as set values, and this information is read together with the sensor data, so the sensor-specific measurement information is automatically stored without any awareness of the sensor-specific measurement information. Data can be set and the input burden during measurement can be reduced. Furthermore, since there are no errors in reading data, there are no errors in the correspondence between measurement locations and data, and measurement accuracy and reliability can be improved. Furthermore, necessary data processing can be performed immediately on the spot, and rapid measurement processing can be performed.
