[Diagram 5] 4 is a flowchart showing the processing of the elevator monitoring system according to the first embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Embodiment 1 1 is a block diagram showing an elevator monitoring system according to embodiment 1. The elevator monitoring system according to embodiment 1 includes an elevator 1, a weather information acquisition device 2, and a monitoring device 3.

[0010] The elevator 1 includes an elevator control panel 101 and a hoist 102 controlled by the elevator control panel 101. An evacuation operation command and an evacuation operation release command, which will be described later, are input to the elevator control panel 101 from the monitoring device 3. When an evacuation operation command is input to the elevator control panel 101, the elevator control panel 101 controls the hoist 102 so that the elevator 1 performs evacuation operation. In the evacuation operation of the elevator 1, a car (not shown) moves to a preset floor, and then the elevator 1 is put into a paused state. When an evacuation operation release command is input to the elevator control panel 101, the elevator control panel 101 controls the hoist 102 so that the evacuation operation of the elevator 1 is released.

[0011] The weather information acquisition device 2 is provided in the building in which the elevator 1 is installed. Weather information for the area in which the building in which the elevator 1 is installed is periodically input to the weather information acquisition device 2 from an information center (not shown). The weather information includes wind speed, wind direction, and rainfall amount per unit time. The weather information input to the weather information acquisition device 2 is output from the weather information acquisition device 2 and input to the monitoring device 3.

[0012] The monitoring device 3 is provided in a building in which the elevator 1 is installed. The monitoring device 3 includes a blowing direction calculation unit 301, a flood amount calculation unit 302, a judgment processing unit 303, and an operation control command unit 304.

[0013] The speed at which rain falls varies with the size of the raindrops. The size of the raindrops varies with the amount of rainfall per unit time. Therefore, the speed at which rain falls varies with the amount of rainfall per unit time.

[0014] The blowing direction calculation unit 301 prestores the falling speed of rain corresponding to the amount of rainfall per unit time. Weather information output from the weather information acquisition device 2 is input to the blowing direction calculation unit 301. The blowing direction calculation unit 301 determines the falling speed of rain using the amount of rainfall per unit time.

[0015] FIG. 2 is an explanatory diagram showing a method of calculating the rainfall direction α by the rainfall direction calculation unit 301 in FIG. w , wind direction D w , and the rainfall speed V r The rain direction α is calculated using the wind direction D w is the wind direction along the horizontal plane. The rainfall velocity V r is the vertical velocity of the rain.

[0016] The rain direction α is the wind speed V w , wind direction D w , and the rainfall speed V r The rain direction calculation unit 301 calculates the rain direction α as a three-dimensional vector from the above. The absolute value of the rain direction α is 1.

[0017] Fig. 3 is a configuration diagram showing a landing floor of a building in which the elevator monitoring system of Fig. 1 is installed. A plurality of openings 401 are formed in the outer wall of the building 4. Rain infiltrates into a landing floor 402 from outside the building 4 through each of the openings 401.

[0018] A landing entrance 403 is formed in the building 4. The landing entrance 403 is opened and closed by the landing door 103 of the elevator 1. Rain that has infiltrated into the landing floor 402 flows along the landing floor 402, passes through the landing entrance 403, and infiltrates into a hoistway (not shown) of the elevator 1.

[0019] The number of openings 401 is set to N, and each opening 401 is assigned a number from 1 to N. Let n be an arbitrary natural number from 1 to N. Let the area of ​​the n-th opening 401 be S. n The direction in which the n-th opening 401 faces is defined as β n In FIG. 3, the number of openings 401 is 12.

[0020] The flood water amount calculation unit 302 calculates the area S n and the direction β in which each opening 401 faces. n are stored in correspondence with each other.

[0021] FIG. 4 shows the direction β in which the opening 401 in FIG. n 4 is an explanatory diagram showing the direction β in which the opening 401 faces. n is a three-dimensional vector. The direction β in which the opening 401 faces n The absolute value of is 1. The direction β in which each opening 401 faces n is a direction perpendicular to the outer wall of the building 4 in which each opening 401 is formed, and is a direction from the outside to the inside of the building 4.

[0022] In FIG. 3, the direction β in which the openings 401 face is the same as that in FIG. n In the illustrated example, the building 4 has a structure in which the direction β of the opening 401 faces is parallel to the horizontal plane. n The opening 401 is inclined with respect to the horizontal plane, or the direction β in which the opening 401 faces n A vertical opening 401 may be included.

[0023] The amount of rainfall R per unit time in the weather information output from the weather information acquisition device 2 is input to the flood amount calculation unit 302. The flood amount calculation unit 302 calculates the area S of each opening 401 by n , the direction β in which each opening 401 faces n, the rain flow direction α, and the amount of rainfall per unit time R are used to calculate the amount of rainfall A per unit time that enters the building 4 through each opening 401.

[0024] Specifically, the flood amount calculation unit 302 first calculates the amount of rainwater blown into each opening 401 per unit area φ using the following formula (1): n Calculate.

[0025] φ n = α β n (1)

[0026] When the value calculated by the above formula (1) is a positive value, the flooding amount calculation unit 302 calculates the value calculated by the above formula (1) as the amount of rain blowing in per unit area at the opening 401, φ n Store it as.

[0027] On the other hand, when the value calculated by the above formula (1) is a negative value, the flooding amount calculation unit 302 sets 0 to the amount of rain blown in per unit area φ n If the value calculated by the above formula (1) is negative, the wind direction D w The direction of the raindrops is from the inside to the outside of the building 4 relative to the opening 401, so that the raindrops do not enter the building 4 through the opening 401.

[0028] Thereafter, the flood amount calculation unit 302 calculates the amount of rainfall A that has entered the building 4 per unit time using the following formula (2).

[0029]

number

[0030] The calculation result of the flood amount calculation unit 302 is input to the judgment processing unit 303. A first threshold value used to judge whether or not to perform evacuation operation and a second threshold value used to judge whether or not to cancel evacuation operation are preset in the judgment processing unit 303. The second threshold value is a value smaller than the first threshold value. The first threshold value and the second threshold value are determined according to the drainage treatment capacity of the elevator shaft of the building 4.

[0031] The determination processing unit 303 determines whether the amount A of rain that has entered the building 4 per unit time, calculated by the flood amount calculation unit 302, exceeds a first threshold value.

[0032] The determination processing unit 303 also determines whether the amount A of rain that has entered the building 4 per unit time, calculated by the flood amount calculation unit 302, has fallen below a second threshold value.

[0033] The determination result of the determination processing unit 303 is input to the operation control command unit 304. When the determination processing unit 303 determines that the amount A of rain per unit time that has entered the building 4 exceeds the first threshold, the operation control command unit 304 outputs an evacuation operation command. The evacuation operation command output from the operation control command unit 304 is input to the elevator control panel 101. When the evacuation operation command is input to the elevator control panel 101, the elevator control panel 101 controls the hoist 102 so that the elevator 1 performs evacuation operation.

[0034] If the determination processing unit 303 determines that the amount A of rain per unit time that has entered the building 4 falls below the second threshold after the operation control command unit 304 outputs the evacuation operation cancellation command. The evacuation operation cancellation command output from the operation control command unit 304 is input to the elevator control panel 101. When the evacuation operation cancellation command is input to the elevator control panel 101, the elevator control panel 101 controls the hoist 102 so that the evacuation operation of the elevator 1 is cancelled.

[0035] Next, an elevator monitoring method in the elevator monitoring system according to the first embodiment will be described. FIG. 5 is a flowchart showing the processing of the elevator monitoring system according to the first embodiment. First, in step S101, a blowing direction calculation step is performed. In the blowing direction calculation step, the blowing direction calculation unit 301 calculates the wind speed V w , wind direction D w , and the rainfall speed V r The rainfall direction α is calculated using the following equation: The rainfall direction calculation step is performed every time the weather information is input to the rainfall direction calculation unit 301.

[0036] Then, in step S102, a flood volume calculation step is performed. In the flood volume calculation step, the flood volume calculation unit 302 calculates the area S n , the direction β in which the opening 401 faces n The amount of rain A per unit time that has entered the building 4 is calculated using the calculated rain inflow direction α and the rainfall amount R per unit time. The flood amount calculation process is performed every time the inflow direction calculation process is performed.

[0037] Thereafter, in step S103, an evacuation determination process is performed. In the evacuation determination process, the determination processing unit 303 determines whether or not the amount of rain A entering the building 4 per unit time exceeds a first threshold. In step S103, if the determination processing unit 303 determines that the amount of rain A entering the building 4 per unit time does not exceed the first threshold, the process of the elevator monitoring system according to embodiment 1 repeats step S103. In the evacuation determination process, the amount of rain A entering the building 4 per unit time calculated in the latest flood amount calculation process is used.

[0038] On the other hand, in step S103, if the judgment processing unit 303 judges that the amount A of rain per unit time entering the building 4 exceeds the first threshold, the processing of the elevator monitoring system of embodiment 1 proceeds to step S104.

[0039] In step S104, an evacuation operation command process is performed. In the evacuation operation command process, an evacuation operation command is output from the operation control command unit 304, and the output evacuation operation command is input to the elevator control panel 101. As a result, the elevator 1 performs evacuation operation.

[0040] After step S104, the processing of the elevator monitoring system according to the first embodiment proceeds to step S105.

[0041] In step S105, a release determination process is performed. In the release determination process, the determination processing unit 303 determines whether or not the amount A of rain that has entered the building 4 per unit time has fallen below the second threshold. In step S105, if the determination processing unit 303 determines that the amount A of rain that has entered the building 4 per unit time is not below the second threshold, the process of the elevator monitoring system according to embodiment 1 repeats step S105. In the release determination process, the amount A of rain that has entered the building 4 per unit time calculated in the latest flood amount calculation process is used.

[0042] On the other hand, in step S105, if the judgment processing unit 303 judges that the amount A of rain per unit time entering the building 4 falls below the second threshold, the processing of the elevator monitoring system of embodiment 1 proceeds to step S106.

[0043] In step S106, an evacuation operation command release step is performed. In the evacuation operation command release step, an evacuation operation release command is output from the operation control command unit 304, and the output evacuation operation release command is input to the elevator control panel 101. This causes the elevator 1 to release the evacuation operation. This ends the processing of the elevator monitoring system according to the first embodiment.

[0044] As described above, the elevator monitoring system according to the first embodiment includes the blowing direction calculation unit 301, the flood water amount calculation unit 302, the judgment processing unit 303, and the operation control command unit 304. The blowing direction calculation unit 301 calculates the wind speed V w , wind direction Dw , and the rainfall speed V r The inundation amount calculation unit 302 calculates the rain inflow direction α by using the area S n , the direction β in which the opening 401 faces n , the calculated rain inflow direction α, and the rainfall amount R per unit time are used to calculate the amount of rainfall A per unit time that has entered the building 4. The determination processing unit 303 determines whether the amount of rainfall A per unit time that has entered the building 4 exceeds a first threshold value. The operation control command unit 304 outputs an evacuation operation command to the elevator 1 based on the determination result of the determination processing unit 303. According to this configuration, the area S of the opening 401 formed in the building 4 is n , the direction β in which the opening 401 faces n The amount of rain A per unit time that has entered the building 4 is calculated using the calculated rainfall direction α and the rainfall amount R per unit time. This makes it possible to improve the accuracy of the calculation of the amount of rain A per unit time that has entered the building 4.

[0045] By improving the accuracy of the calculation of the amount of rainfall A per unit time that has entered the building 4, it is possible to prevent the car from falling into water that has accumulated in the hoistway in which the elevator 1 is installed, thereby reducing the occurrence of breakdowns in the elevator 1. Furthermore, by improving the accuracy of the calculation of the amount of rainfall A per unit time that has entered the building 4, it is possible to avoid unnecessary evacuation operations of the elevator 1, thereby improving the operating rate of the elevator 1. As a result, it is possible to improve the convenience of the elevator 1 for users.

[0046] In addition, the blowing direction calculation unit 301 calculates the rainfall velocity V using the rainfall amount R per unit time. r According to this configuration, it is possible to further improve the accuracy of calculation of the rainwater blowing direction α.

[0047] The elevator monitoring method according to the first embodiment includes a blowing direction calculation step, a flooding amount calculation step, an evacuation determination processing step, and an operation control command step. w , wind direction D w , and the rainfall speed V r The rain inflow direction α is calculated using the above formula. The inundation amount calculation process is performed after the inundation direction calculation process. In the inundation amount calculation process, the area S n , the direction β in which the opening 401 faces n , the calculated rain inflow direction α, and the rainfall amount R per unit time are used to calculate the amount of rain A that has entered the building 4 per unit time. The evacuation determination processing step is performed after the flood amount calculation step. In the evacuation determination processing step, it is determined whether the amount of rain A that has entered the building 4 per unit time exceeds a first threshold. The operation control command process is performed after the evacuation determination processing step. In the operation control command process, an evacuation operation command is output to the elevator 1 based on the determination result of the evacuation determination processing step. According to this configuration, the area S of the opening 401 formed in the building 4 is calculated. n , the direction β in which the opening 401 faces n The amount of rain A per unit time that has entered the building 4 is calculated using the calculated rainfall direction α and the rainfall amount R per unit time. This makes it possible to improve the accuracy of the calculation of the amount of rain A per unit time that has entered the building 4.

[0048] Moreover, the elevator monitoring method according to the first embodiment includes a release determination processing step and an evacuation operation command release step. The release determination processing step is performed after the evacuation operation command step. In the release determination processing step, it is determined whether or not the amount of rain A per unit time that has entered the building 4 has fallen below a second threshold. The evacuation operation command release step is performed after the release determination processing step. In the evacuation operation command release step, an evacuation operation release command is output to the elevator 1 based on the determination result of the release determination processing step. According to this configuration, the evacuation operation of the elevator 1 can be released when the amount of rain A per unit time that has entered the building 4 has fallen below the second threshold after the elevator 1 has performed evacuation operation.

[0049] In the elevator monitoring system according to the first embodiment, the rainfall direction calculation unit 301 calculates the rainfall velocity V using the rainfall amount R per unit time. r However, the rainfall direction calculation unit 301 determines the rainfall velocity V using the rainfall amount R per unit time and a preset calculation formula. r The raindrop direction calculation unit 301 may be configured to calculate the raindrop falling speed V r In this case, the rainfall velocity V calculated by the rainfall direction calculation unit 301 may be calculated by setting the rainfall velocity V r There is no need to determine or calculate

[0050] Furthermore, in the elevator monitoring system according to the first embodiment, a configuration has been described in which the weather information acquisition device 2 is provided in the building 4 in which the elevator 1 is installed. However, the weather information acquisition device 2 may be provided outside the building 4. In this case, for example, the weather information acquisition device 2 may be provided in an information center.

[0051] In the elevator monitoring system according to the first embodiment, the weather information is input from the information center to the weather information acquisition device 2. However, if the weather information acquisition device 2 has at least one of an anemometer, a wind vane, and a rain gauge, and the wind speed V w , wind direction D w , and the amount of rainfall per unit time R may be measured.

[0052] In addition, in the elevator monitoring system according to the first embodiment, a configuration has been described in which the monitoring device 3 is provided in the building 4 in which the elevator 1 is installed. However, the monitoring device 3 may be provided outside the building 4. In this case, for example, the monitoring device 3 may be provided in an information center. [Explanation of symbols]
