  FIG. 7 is a block diagram showing the configuration of the control device 18.

  The control device 18 includes a control unit 41, a recording unit 42, an interface unit 43, and a schedule storage unit 44.

  The control unit 41 performs processing for acquiring environmental information of each floor measured by the measuring device 15, processing for recording the environmental information in the recording unit 43, processing for transmitting to the main control device 21, and the like. The recording unit 42 is composed of a large-capacity storage device such as a hard disk, for example, and records and stores the environmental information of each floor obtained by the measuring device 15. The interface unit 42 is a part that performs transmission / reception processing of data with the main control device 21. Here, the interface unit 42 receives measurement conditions, a measurement start signal, and the like from the main control device 21 and is obtained by the measurement device 15. The environment information of each floor is transmitted to the main controller 21.

  Next, the operation of the embodiment will be described.

  FIG. 8 is a flowchart showing the operation of the elevator environment monitoring system in the same embodiment, and shows a flow of processing mainly executed by the control device 18. The system configuration will be described assuming the configuration of FIG.

  First, when measuring environmental information, measurement conditions are input (step S11). This is which one of the first to third measurement functions provided in the measurement device 15 described above is used, what is measured, measurement period (measurement start time, measurement end time), measurement target floor, etc. Is input by the operator through the main controller 21 by a predetermined operation.

  Here, when the measurement start time designated in advance as the measurement period is reached (Yes in step S12), the operation mode of the car 11 is switched from the normal mode to the measurement mode (step S14). The normal mode is a normal driving service, that is, a mode in which the car 11 is driven in response to a hall call or a car call (step S13). On the other hand, the measurement mode is a special operation mode for environmental measurement. For example, when all floors of the building 1 are designated as measurement target floors, the lowest floor to the top floor are used. The car 11 reciprocates at a predetermined speed.

  When the measurement device 15 is activated by switching the measurement mode and the preparation of the devices necessary for environmental measurement is completed, the measurement processing of the environmental information by the measurement device 15 is started (step S16). At this time, the car 11 is operated in the measurement mode, and environmental information of each floor is continuously measured in the height direction of the building 1 as the car 11 moves up and down. The control device 18 acquires environmental information of each floor from the measuring device 15 (step S17), and sequentially records the environmental information in the recording unit 42 (step S18).

  During the measurement period, the measurement process by the measurement device 15 is repeated, and the environmental information of each floor obtained at that time is sequentially recorded in the recording unit 42. When the measurement end time designated in advance is reached (Yes in step S19), the environmental information of each floor recorded in the recording unit 42 is transmitted to the main controller 21 via the tail code 20 (step S20).

  The main control device 21 analyzes the environmental information for each floor and performs predetermined processing such as displaying the analysis result on the screen of the monitoring device 22 (step S21).

  More specifically, if it is specified that the temperature, the humidity, and the wind speed are measured using the first measurement function of the measurement device 15 as the measurement condition, the measurement is performed as the car 11 moves up and down. Environmental information on the temperature, humidity, and wind speed of each floor can be obtained from the device 15. By analyzing this environmental information for each floor, for example, a floor with an abnormally high temperature (a floor exceeding a predetermined temperature), a floor with an abnormally high humidity (a floor exceeding a predetermined humidity), or a floor with an abnormally strong wind (predetermined) When a floor exceeding the wind speed is detected, it is possible to take measures such as displaying a warning to that effect.

  In addition, if the generation state of harmful substances that adversely affect the human body is measured using the second measurement function of the measuring device 15, whether or not pre-designated harmful substances such as nitrogen oxides and sulfur are generated. Are analyzed for each floor, and a warning is displayed when a floor where harmful substances are generated is detected. Such harmful substances are not only generated from each floor of the building 1, but may also be generated from, for example, a factory or the like around the floor. As described above, the measurement is performed by the second measurement function of the measurement device 15 including the case where harmful substances generated from the surroundings flow into the building 1.

  If the third measurement function of the measuring device 15 is used to measure the amount of dust in the air that affects the explosives, the amount of dust is analyzed for each floor and the explosives are placed. It is possible to take measures such as displaying a warning when the amount of dust on the floor has exceeded a predetermined amount.

  Thus, by installing the measuring device 15 in the car 11, the environmental information of each floor can be efficiently acquired in the height direction of the building 1. Thereby, the environmental information can be analyzed for each floor, and when any abnormality is detected, it can be quickly dealt with.

  As shown in FIG. 4, the function of the control device 18 may be incorporated in the main control device 21. In this case, the environmental information transmission process in step S20 is unnecessary, and immediately after the measurement is completed, the environmental information is immediately transmitted. Analysis processing is executed for each floor.

  Moreover, as shown in FIG. 5, the environmental information of each floor can be easily acquired in the height direction of the building 1 as described above by installing the measuring device 15 on the counterweight 14 as well.

  Further, the measurement may be performed by arbitrarily combining the first to third measurement functions provided in the measurement device 15, and the measurement other than the first to third measurement functions is performed. May be.

  Further, in the above embodiment, the car 11 is specially operated by switching the measurement mode to acquire the environmental information of each floor. However, when the car 11 is moving in the normal operation mode, each floor It is also possible to acquire floor environmental information.

  Moreover, in the said embodiment, the environmental information of each floor obtained from the measuring apparatus 15 with the raising / lowering operation | movement of the cage | basket | car 11 was accumulate | stored in the recording part 42, and was recorded on the recording part 42 at the predetermined timing. Although the environment information is transmitted to the main control device 21 and analyzed, the environment information of each floor obtained from the measuring device 15 may be analyzed and processed in the control device 18.

  In the above-described embodiment, the worker inputs the measurement start timing and the measurement end timing by a predetermined operation. However, schedule information in which a measurement period is set in advance is registered in the schedule storage unit 44, and the schedule is set. You may make it perform a measurement process according to information. Thus, for example, 6: 0 to 6:30, 12: 0 to 12:30, 18: 0 to 18:30, etc., each time in advance, the operator does not specify the timing of measurement every day. Measurement processing can be performed in a given time zone. In this case, if the measurement target floor is included in the schedule information, the environment information of the measurement target floor can be acquired based on the schedule information.

  Furthermore, as shown in FIG. 9, it is also possible to construct a system in which the monitoring center 62 remotely monitors the environmental information of each floor of a large number of buildings 1a, 1b, 1c. In this case, measuring devices 15a, 15b, and 15c are installed in elevator cars 11a, 11b, and 11c or counterweights 14a, 14b, and 14c in the buildings 1a, 1b, and 1c, and measurement is performed by the measuring devices 15a, 15b, and 15c. The environmental information of each floor is transmitted from the monitoring center 62 via the network 61. The monitoring center 62 accumulates these environmental information in the database 63 for each building. Then, by analyzing the environmental information for each building, the above-described alarm or the like is taken when any abnormality is detected.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various forms can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be omitted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
