[Technical background of the invention and its melting point]

Generally, when detecting and measuring the distribution of physical quantities such as temperature and humidity, radiation dose, dust density, and special gas concentration in a relatively wide spatial plane, the measurer must bring a detector or measuring device suitable for the physical quantity to be measured. In addition, when moving on the spatial plane, the operator must carry a floor map, an equipment layout diagram, a data sheet for recording the measurement results, etc. to identify the measurement position. Then, while moving, we measure physical quantities at each of a number of measurement positions and transfer the measurement results to the measurement location,
It is recorded on the data sheet along with measurement conditions such as measurement time. Based on the data recorded in this data sheet, a distribution map of physical quantities within the measurement space plane is created and the distribution state is manually determined.

As a result, the measurement work becomes complicated and the work efficiency may decrease. Furthermore, if the measurement target space is a dangerous space such as a radiation field, it is not preferable to take into account radiation exposure for the measurer, and it is also not desirable to process data quickly with a 1llll fixed trowel. requested.

An operation mechanism that specifies a measurement point and detects the specified measurement point, a detection mechanism that detects a physical quantity at the measurement point specified by this operation mechanism, and a detection signal from this detection mechanism and drawing from the operation mechanism. The configuration includes a storage mechanism that inputs signals and measurement position signals, calculates and stores them, and an arithmetic processing mechanism that inputs signals from the storage mechanism and processes them to create a physical quantity distribution map or the like.

That is, a map diagram of the measurement area or a diagram of the equipment arrangement is drawn using the operating mechanism and is temporarily stored in the storage mechanism. Then, the measurement position at the time of measurement is specified, the detection mechanism detects the physical quantity at that position, and the detection signal and measurement position signal are sent to the storage mechanism. The storage mechanism calculates and stores this. The data stored in the storage mechanism is then processed by the arithmetic processing unit to create, for example, a physical quantity distribution diagram.

This eliminates the need for the conventional work of reading measurement data from a measuring device for each measurement position, determining the measurement position from a drawing, etc. carried, and entering it into a data sheet, simplifying the work and shortening the work time. , it is possible to improve workability.

For example, when the drawing operation mode is set, the voltage pen 14 is prompted to change the situation at the measurement location.
Alternatively, a map, layout, or situation diagram of the site is drawn on the resistance sheet 16 via the confirmation paper sheet 17 so that the position to be measured can be accurately grasped. The configuration is such that this is detected as two-dimensional coordinates by diode switch circuits 18 and 19. Further, when the measurement mode is set using the manual key operation section 12, the measurer touches the position to be measured using the voltage pen 14 while referring to the confirmation paper sheet I7 in which the record of the drawing input remains. In this case as well, the designated measurement position is detected as two-dimensional coordinates by the diode switch circuits 18 and 19.

This is the configuration recorded in the memory circuit 25. Further, the measurement position indicated by the voltage pen 14 during measurement is detected as two-dimensional coordinates by the diode switch circuits 18 and 19, and sent to the detection signal processing circuit 22 and the data processing/control circuit 24 via the interface 15. The physical sewing detection sensor 2 is always in operation, and the detection signal processing circuit 22 transfers the input detection signal of the measurement position to the data processing/control circuit 24.

Reference numeral 4 designates a structure for converting and organizing the detection signal and measurement position signal into a predetermined signal format, and transmitting and storing the data in the storage memory circuit 25 as a pair of data. - Therefore, simply by sequentially indicating measurement positions according to the drawing drawn with the voltage pen 14, the physical quantity at the measurement position is detected and stored in the storage memory circuit 25 as paired data. Only the arithmetic processing mechanism is shown in the figure. This arithmetic processing mechanism is composed of an arithmetic circuit dedicated to physical quantity distribution processing, a graphic display circuit 29, and an I10 output device 30.

The storage mechanism is integrated, compact, and portable, and is configured to be carried by the measurer during measurements.

Based on the above configuration, a case will be described in which, for example, the temperature distribution near the piping of a certain plant is measured. First, the input key operation section 12 is used to set the mode to the drawing operation mode. Then, the voltage pen 14 draws a diagram of the pipe installation state on the resistance sheet 16 via the confirmation paper sheet 17, as shown in FIG. This drawn diagram is detected as two-dimensional coordinates by the diode switch circuits 18 and 19 and sent to the data processing/control circuit 24 via the interface 15.
There, the signal is converted into a predetermined signal form, organized, and sent to the storage memory circuit 25 for storage. Next, the input key operation unit 12 is used to set the mode to measurement mode.

Then, the measurer moves near the piping to be measured and uses the voltage pen 14 to sequentially point and touch measurement positions while referring to the confirmation paper sheet 17. The measurement position indicated by the voltage pen 14 is detected as two-dimensional coordinates by the diode switch circuits 18 and 19 and sent to the detection signal processing circuit 22 and the data processing/control circuit 24 via the interface 15. The detection signal processing circuit 22 data-processes/processes the input temperature detection signal at the measurement position.
The signal is sent to the control circuit 24.

The data is then sent to the storage memory circuit 25 as a pair of data.

The data is input to the distribution processing dedicated arithmetic unit 28, subjected to arithmetic processing, and sent to the graphic display circuit 29. Then, the graphic display circuit 29 produces a graphic display as shown in FIG. 4, which allows the state of temperature distribution in the vicinity of the piping to be grasped. In FIG. 4, numerals 31 and 32 indicate drawn piping, and numeral 33 indicates a valve inserted in the piping 32. Also, the numbers written indicate the temperature at the designated measurement position. The temperature distribution near the piping thus obtained is recorded and filed in the I10 output device 30.

As described above, according to the physical quantity distribution measuring device according to the present embodiment, if the installation state of the piping to be measured is drawn on the resistance sheet I6 using the voltage P/14 and stored as drawing data in the storage memory circuit 25, At the time of measurement, by simply instructing the voltage pen 14 to a fixed position on the side, the temperature at that measurement position can be detected and sequentially stored in the storage memory circuit 25 as pair data, so that the measurement work is done by only one set. Sexuality also improves. Furthermore, since the working time is greatly reduced, when measurements are carried out in dangerous areas such as radiation fields, it is possible to reduce the radiation exposure of the personnel on the side, and to greatly improve safety. In addition, you can easily draw and input drawings to understand the measurement position according to the actual site situation, and the measurement position can be recognized and specified in the same coordinate system as the input drawing, so the input of the measurement position is uniform. It is possible to obtain highly reliable data because the distribution can be shown on the input diagram. Furthermore, unlike in the past, it is no longer necessary for the measurer to record the data from the measuring device on the welt removal data sheet each time, so accurate image data can be obtained without misreading by the measurer. Furthermore, in order to accurately grasp the distribution state, it is possible to obtain the absolute value of physical quantities such as temperature, the measurement position, and the surrounding situation between the measurement wall and the like in a signal format suitable for calculation processing by computers, etc. This makes data processing easier and reduces processing time.

In the above embodiment, the digitizing circuit 13 is composed of a voltage pen 14, a resistor sheet 16, and diode switch circuits 18 and 19, but the present invention is not limited to this. For example, a matrix contact switch type, There are methods that use a combination of a light pen and photodetecting elements arranged in a matrix, methods that are determined based on the ratio of current or voltage, and methods that are determined based on capacitance, and similar effects can be achieved using these methods. I can do it. In addition, the physical quantities to be measured include not only temperature but also humidity, illuminance, radiation dose, dust density, specific gas concentration, etc.
