Description

  The present invention relates to a contour map creating apparatus that can easily create a contour map in a short time.

  Conventionally, contour maps connected by contour lines such as contour lines of topographic maps and isobars of weather maps are known. Conventionally, in order to create a contour map, a number of measurement points to be measured are set in a grid pattern on the map, the measurer moves to the measurement point with a measuring instrument, and the altitude is measured by the measuring instrument at each measuring point. Alternatively, the contour map is created by measuring the atmospheric pressure, finding the position where the altitude or the atmospheric pressure is the same based on a large number of measurement values measured at each measurement point, and connecting them with a line.

  On the other hand, in recent years, for example, airfields, nuclear power plants, thermal power plants, garbage disposal facilities, high-rise buildings, various factories, aircraft, railways, automobiles, etc., noise, vibration, temperature, humidity, wind power, gas, etc. In order to grasp the environmental values of components and the like, an environmental value is measured and a contour map of the environmental value is created.

  In creating a contour map, for example, when creating a contour map of noise, conventionally, a number of grid-like measurement points to be measured are first identified on the map, and a measurer carrying a sound level meter and a map is required. Move to one of the measurement points set on the map, perform measurement using the sound level meter at this measurement point, record the noise measurement value at this time on the map, or record it in a data book, etc. Then, the measurer moves to another measurement point specified on the map and repeats the work of recording the measurement and the noise measurement value as described above, and then the noise measurement value at each measurement point obtained in this way. This data was input to a computer, the distribution of noise values was obtained, and a contour map of noise values was created.

In the sound level meter that measures the sound pressure level and displays a correction based on human hearing, a scale for measuring the distance from the sound level meter to the measurement reference point is attached to the main body of the sound level meter. A sound level meter having a distance measuring function is described in Patent Document 1.

  However, conventionally, in order to create a contour map, a measurer who carries a measuring instrument and a map sequentially goes around a number of measurement points specified on the map and records and records measurement values. There is a problem that it takes time for the measurer to move while specifying the measurement point while looking at the map, and furthermore, the contour record is created by inputting the obtained record data into the computer installed in the office etc. Therefore, there is a problem that it takes time to create a contour map. In addition, conventionally, there is a possibility that a place different from the place specified by the measurer may be misunderstood as a measurement point, a measurement value may be recorded incorrectly, or a computer input error may occur. Was. Further, when a contour map is created using the sound level meter disclosed in Patent Document 1, the same problem as described above has been encountered. Furthermore, the sound level meter disclosed in Patent Document 1 is configured to simultaneously measure the noise and the distance between the measurement reference point (sounding body), and the position of the measurement reference point (sounding body).
