2. Description of the Related Art Conventionally, in server rooms, communication machine rooms, and the like in which computer devices and the like are installed intensively, the indoor temperature distribution varies due to the amount of heat generated by devices installed in server racks, and air conditioning becomes inefficient. Therefore, the indoor temperature distribution is made uniform by measuring the indoor temperature at multiple points, adjusting the air blowing angle and air blowing area of the air conditioning, and stirring the indoor air, etc. Energy is reduced (see, for example, Patent Document 1 as an air conditioning control system).
In addition, regarding the measurement of the indoor environment such as the indoor temperature, the environment that represents the indoor environment stipulated in the Ministerial Ordinance related to the “Law for Ensuring Hygienic Environment in Buildings” (Building Sanitation Management Act, Building Management Act) It is desirable to measure elements. The value of such an environmental element is generally measured by a thermometer installed on a wall or the like. Alternatively, when measuring the indoor environment in a space away from a wall or a server rack in the server room, for example, an operator uses a handy terminal device that can measure the indoor environment such as temperature.

  In the present embodiment, these measurement result tables may be set so that the background color of the cell in which the measurement result is input is changed according to the value of the measurement result by the function of the spreadsheet software. For example, the background color is set to be light when the temperature is low, and the background color is set to dark when the temperature is high. The background color may be light blue when the temperature is low and red when the temperature is high. For example, the environment measuring device 10 includes a display unit in itself, and the temperature measurement result information stored in the storage unit 13 in this manner is displayed in a table format by spreadsheet software, so that the user can distribute the temperature. Can be grasped visually. For example, if the user looks at the table as shown in FIG. 5, as the whole goes from (a) to (c), that is, the closer to the floor, the lower the temperature, or the temperature in a certain space. It is possible to grasp variations at a glance. Moreover, the environment measuring device 10 generates an image as shown in FIG. 6 based on such a measurement result, and visually calculates the temperature distribution of the horizontal cross sections (a), (b), and (c) in the space. It may be possible to grasp it automatically.

FIG. 7 shows an example of a measurement result table of a vertical section generated by the central control unit 11. The central control unit 11 generates a measurement result table for a vertical section corresponding to a measurement point in the space, similarly to the measurement result table for a horizontal section. According to such a measurement result table of the vertical section, it is possible to visually grasp the temperature distribution of the vertical sections (a), (b), and (c) in the space as shown in FIG. As described above, the central control unit 11 uses a spreadsheet software or the like to tabulate or graph the measurement result table according to the vertical direction or horizontal direction in the space, thereby visually in various formats. Temperature information can be grasped. Such a measurement result table may be generated using spreadsheet software, or a program for drawing a measurement result table or a graph corresponding to the measurement result table may be prepared and generated. Moreover, you may make it produce | generate the information which displays such a measurement result table | surface on a web.

And if the position sensor 15 transmits the color information of yellow and green to the movement control part 12 at the point P2, the movement control part 12 will judge the left turn and will output the movement command which makes the left turn to the traveling part 14. . The traveling unit 14 causes the environment measuring device 10 to turn left and travel.

  And if the position sensor 15 transmits the color information which shows yellow to the movement control part 12 at the point P3, it will determine with the movement control part 12 being a measurement point which performs a stop and temperature measurement, and will be to the driving | running | working part 14. The movement command indicating the stop is output. Then, the traveling unit 14 stops traveling of the environment measuring device 10. In addition, the movement control unit 12 transmits a measurement point notification to the central control unit 11. When receiving the measurement point notification, the central control unit 11 transmits a measurement command to the environment measurement sensor control unit 18.
