Description

  The present invention relates to an elevator remote monitoring device that has a function of predicting the state of elevator equipment in a pit during flooding of an elevator pit and a function of instructing maintenance personnel by predicting the state.

  Conventionally, when an elevator hoistway pit is flooded, the operation of the liquid level detection device set in the pit causes the car to arrive at a specific floor and stop. Furthermore, two liquid level detection devices are installed in the pit so as to have different heights from the floor. When the first detection device detects flooding, the car is retreated to a specific floor, and in this state, the second detection device is flooded. There is known a technique for shutting off the power supply when a power supply is detected.

  Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1 (schematic diagram).

  In FIG. 1, reference numeral 1 denotes an elevator hoistway pit. Reference numeral 2 denotes a first submersion detector (hereinafter referred to as a float switch) that is installed in the pit and detects submersion in the pit. An elevator control device 3 is installed above the installation location of the first float switch 2.

  A second float switch 5 is installed below a predetermined dimension L1 (4) of the device device 3.

  The distance between the first float switch 2 and the second float switch 5 is defined as a measurement dimension L2 (6). The water level when the pit 1 is submerged is defined as a water level 7.

  Reference numeral 8 denotes an elevator control panel. Reference numeral 8 a denotes an input processing device in the control panel 8, which controls the operation of the elevator according to the state of the equipment device 3. Reference numeral 9 denotes an elevator monitoring terminal device. 9a is an input processing device in the monitoring terminal device 9, 9b is a communication processing device, and 9c is an arithmetic processing device.

[Example 1]
Hereinafter, the operation after the elevator flooding according to the first embodiment will be described with reference to FIG.

  After the occurrence of flooding, ST001 in FIG. 2 determines whether the water level 7 has reached the predetermined position of the first float switch 2. When the water level 7 reaches the predetermined position of the first float switch 2, the first float switch 2 transmits a water level detection signal to the input processing device 9 a of the monitoring terminal device 9.

  When the monitoring terminal device 9 receives it, the communication processing device 9b issues a flood report to the control center 10 (ST002). After the control center 10 receives the flood report, the communication processing device 10a contacts the worker 11. On the other hand, the timer set in the monitoring terminal device 9 starts counting (ST003). Thereafter, the arithmetic processing unit 9c determines whether or not the water level 7 has reached the predetermined position of the second float switch 5 (ST004). When the water level 7 reaches the position of the second float switch 5, the second float switch 5 transmits a water level detection signal to the input processing device 9 a of the monitoring terminal device 9.

  Next, the count of the timer that started counting in ST003 is completed (ST005), and the time Time is recorded. Then, the arithmetic processing unit 9c of the monitoring terminal device 9 calculates the flooding speed and the equipment flooding time (ST006). Flooding speed V = measured dimension L2 / time Time. Equipment flooding time Timelimit = predetermined dimension L1 / flooding speed V

Then, the device flooding time Timelimit is compared with a predetermined time T (ST007). If it is shorter than the predetermined time T, an emergency dispatch is transmitted from the monitoring terminal device 9 to the control center 10 (ST008). If it is longer than the predetermined time T, the risk of equipment flooding is transmitted from the monitoring terminal device 9 to the control center 10 (ST009). After receiving the information, the control center 10 contacts the worker 11 (ST010).
[Example 2]
Hereafter, the operation | movement after the elevator flooding by Example 2 is demonstrated with reference to FIG.

  After the occurrence of flooding, ST 101 in FIG. 3 determines whether the water level 7 has reached the predetermined position of the first float switch 2. When the water level 7 reaches the predetermined position of the first float switch 2, the first float switch 2 transmits a water level detection signal to the input processing device 9 a of the monitoring terminal device 9.

  When the monitoring terminal device 9 receives it, the communication processing device 9b issues a flood report to the control center 10 (ST102). After the control center 10 receives the flood report, the communication processing device 10a contacts the worker 11. On the other hand, the timer set in the monitoring terminal device 9 is started (ST103).

  Thereafter, it is determined by the arithmetic processing unit 9c whether or not the water level 7 has reached the predetermined position of the second float switch 5 (ST104). When the water level 7 reaches the predetermined position of the second float switch 5, the second float switch 5 transmits a water level detection signal to the input processing device 9 a of the monitoring terminal device 9.

  Next, the counting of the quimmer that started counting in ST103 is ended (ST105), and the time Time is recorded. And the arithmetic processing unit 9c of the monitoring terminal device 9 calculates the flooding speed and the equipment flooding time (ST106). Flooding speed V = measured dimension L2 / time Time. Equipment flooding time Timelimit = predetermined dimension L1 / flooding speed V

  Thereafter, the monitoring terminal device 9 transmits the equipment flood time Timelimit to the control center 10 (ST107).

  The control center 10 compares the equipment flooding time Timelimit with a predetermined time T determined in advance (ST108). If it is shorter than the predetermined time T, the emergency dispatch is notified to the worker 11 (ST109). If it is longer than the predetermined time T, the operator 11 is informed of the possibility of equipment flooding (ST110).

  According to the above-described preferred embodiments of the present invention, it is possible to issue an elevator apparatus state prediction method capable of preventing the elevator control apparatus from being damaged or abnormal due to pit flooding, and to issue a work instruction to the maintenance staff based on the prediction.
