Definitions

  • This disclosure relates to elevator systems.
  • the monitoring device stores the position of the elevator car at the time the request signal was received as a specific car position each time it receives a request signal from the center device, and if it is not possible to send an alarm signal to the center device, it selects a retry car position from among the multiple specific car positions stored, controls the control device so that the car is located at the retry car position, and is configured to again send an alarm signal to the center device with the car located at the retry car position.
  • a monitoring device that monitors the elevator is installed on top of the car.
  • communication is carried out using a communication device connected to the monitoring device, but there is an issue with this, as it cannot detect floors with poor signal conditions.
  • the purpose of this disclosure is to provide an elevator system that can detect floors with poor radio wave conditions.
  • the elevator system is an elevator system equipped with a monitoring device that is installed in the car and monitors the elevator's operating status, and a communication device that is connected to the monitoring device and communicates wirelessly with a base station.
  • the monitoring device performs a radio wave check to check the strength of the radio waves received by the communication device, and is configured to detect floors where the radio wave strength meets a standard and floors where the radio wave strength does not meet the standard.
  • This disclosure makes it possible to provide an elevator system that can detect floors with poor radio wave conditions.
  • FIG. 1 is a diagram showing an elevator system according to a first embodiment.
  • FIG. 1 is a block diagram showing a configuration of an elevator system.
  • FIG. 2 is a block diagram of a monitoring device. 4 is a radio wave reception status management table stored in a storage device of a monitoring device. 4 is a flowchart showing an example of operation according to the first embodiment;
  • FIG. 2 is a diagram illustrating an example of a configuration for implementing the functions of a control device and a center device in the first embodiment.
  • FIG. 1 is a diagram showing an elevator system 1 according to a first embodiment.
  • an elevator 3 is provided in a building 2.
  • a car 4 of the elevator 3 is installed so as to move up and down in a hoistway 12 by a hoisting machine (not shown).
  • the hoistway 12 passes through each floor of the building 2.
  • the floors are the first floor to the third floor.
  • the elevator system 1 of this embodiment is equipped with a monitoring device 5 that is installed in the car 4 and monitors the operating status of the elevator 3.
  • the monitoring device 5 is installed, for example, on top of the car 4.
  • the control device 6 controls the operation of the car 4.
  • the monitoring device 5 does not have to be connected to the control device 6. Since the monitoring device 5 does not have to be connected to the control device 6, it is possible for the monitoring device 5 to monitor elevators 3 made by other companies.
  • FIG. 2 is a block diagram showing the configuration of the elevator system 1.
  • a 4G modem 7 is connected to the monitoring device 5.
  • the modem 7 is an example of a communication device that performs wireless communication with a base station 9 of a communication network 8.
  • the monitoring device 5 is connected to a center device 10, which is a server, via the modem 7, the base station 9, and the communication network 8.
  • the center device 10 is installed in a monitoring center 11 that is located in a building separate from the building 2.
  • FIG. 3 is a block diagram of the monitoring device 5.
  • the monitoring device 5 has a CPU 5a, a RAM 5b which is a storage device, a ROM 5c which is a storage device, a wireless communication unit 5d, a display unit 5e, an operation unit 5f, and an acceleration sensor 5g.
  • the monitoring device 5 detects a malfunction of the elevator 3 using the acceleration sensor 5g. For example, if the acceleration sensor 5g detects that the car 4 has suddenly stopped, the monitoring device 5 detects that the elevator 3 has malfunctioned. In addition, if the door sensor detects that the door of the car 4 is closed but the car 4 does not depart, the monitoring device 5 detects that the elevator 3 has malfunctioned.
  • the monitoring device 5 can detect which floor the car 4 is on by using the acceleration sensor 5g. For example, if the acceleration detected by the acceleration sensor 5g is upside down, it can detect that the car 4 is on the top or bottom floor. The monitoring device 5 can also detect how many floors the building has by counting the number of times it stops at an intermediate floor. The monitoring device 5 can then detect which floor the car 4 is on by using the acceleration sensor 5g to detect the distance traveled from the top or bottom floor.
  • the monitoring device 5 If the monitoring device 5 has already performed a radio wave check on the same floor within a certain period of time, it will skip the radio wave check. This makes it possible to avoid performing radio wave checks more frequently than necessary.
  • the monitoring device 5 When the monitoring device 5 performs a radio wave check, it resets the power supply of the modem 7. This causes the modem 7 to redo location registration and other operations, allowing the radio wave conditions on that floor to be detected more accurately.
  • the monitoring device 5 treats it as if the radio wave check has not been performed. This allows the radio wave check to be performed again the next time the car stops at that floor.
  • the monitoring device 5 If the monitoring device 5 detects a floor where the radio wave strength does not meet the standard, it will report that a floor where the radio wave strength does not meet the standard has been detected when the vehicle stops at another floor. If the report is unsuccessful, it will report in the same way when the vehicle stops at another floor. This ensures that reports are sent reliably.
  • FIG. 4 shows a radio wave reception status management table stored in the storage device of the monitoring device 5.
  • the storage device of the monitoring device 5 is capable of storing the date and time of radio wave reception failure and the date and time of radio wave reception success for each floor.
  • FIG. 5 is a flowchart showing an example of operation according to the first embodiment.
  • the monitoring device 5 judges whether the cage 4 has stopped at a floor. If the cage 4 has stopped at a floor, it judges whether the date and time when radio waves were successfully received at that floor is within a certain date and time. If the date and time when radio waves were successfully received at that floor is within the certain date and time, it is considered that a radio wave check is not necessary, and the process proceeds to step S8. If the date and time when radio waves were successfully received at that floor is not within the certain date and time, the process proceeds to step S3, and the monitoring device 5 starts a radio wave check.
  • step S5 it is judged whether the cage 4 has moved during the radio wave check, and if the cage 4 has moved, the process of this flowchart is terminated. If the cage 4 has not moved during the radio wave check, it is determined whether the radio wave strength meets the criteria (step S5).
  • the monitoring device 5 determines whether there is a history of failed radio reception (step S8). If there is a history of failed radio reception, the monitoring device 5 notifies the center device 10 of the existence of a history of failed radio reception together with floor information (step S9). The monitoring device 5 determines whether the notification was successful (step S10), and if the notification was successful, deletes the history of failed radio reception (step S11).
  • a floor with poor radio wave conditions is detected, and when the user moves to a floor with good radio wave conditions, a report can be sent to the center device 10.
  • a report can be sent to the center device 10.
  • the car 4 may be moved to a floor with good radio wave conditions when it is time for the monitoring device 5 to collect data. This makes it possible to more reliably prevent failure to receive radio waves when it is time for the monitoring device 5 to collect data.
  • FIG. 6 is a diagram showing an example of a configuration for realizing the functions of the control device 6 and the center device 10 in embodiment 1.
  • the processing circuit may be dedicated hardware 600.
  • the processing circuit may include a processor 601 and a memory 602.
  • a part of the processing circuit may be formed as dedicated hardware 600, and the processing circuit may further include a processor 601 and a memory 602.
  • a part of the processing circuit is formed as dedicated hardware 600.
  • the processing circuit further includes a processor 601 and a memory 602 in addition to the dedicated hardware 600.
  • a processing circuit part of which is at least one dedicated hardware 600, may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination of these.
