Description

Elevator signal transmission device

Technical Field

The invention relates to an elevator signal transmission device.

Background

In general, in an elevator, a modification operation called update (modernization) is performed as necessary for the purpose of coping with aging, improving functions, and the like. In this retrofitting operation, a function of transmitting a new type of signal for improving the elevator function or the like may be added between an elevator monitoring panel for monitoring the operation of the elevator and an elevator control panel for controlling the elevator. For example, there are cases where the following functions are added: when the elevator monitoring panel receives a fire detection signal from a fire alarm, the elevator control panel transmits an instruction for controlling operation in the event of a fire.

Jp 2006-321576 a describes the following structure: signals are wirelessly transmitted between the car and an elevator control device that controls driving of a hoisting machine for raising and lowering the car.

In the case where a new type of signal is transmitted between the elevator monitoring panel and the elevator control panel as described above, a signal line for transmitting the signal into the hoistway needs to be led out from the elevator monitoring panel and connected to the relay panel, or connected to the elevator control panel on the upper side of the building. In this case, the signal line needs to be wired outside the hoistway in the building, but since many other signal lines are often disposed outside the hoistway, it is difficult for an elevator facility dealer to wire the additional signal line outside the hoistway. Therefore, wiring of the signal line needs to be requested to the electric construction company, which causes an increase in cost for the elevator equipment company. In addition, when many signal lines are arranged, the possibility of disconnection due to deterioration of the signal lines increases. In addition, when the switch is attached to the elevator monitoring panel or the specification of the monitoring panel is changed, a new type of signal needs to be transmitted between the monitoring panel and the elevator control panel. The above-described problems cannot be solved by the structure described in japanese patent application laid-open No. 2006-321576.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. In the following, the same elements are denoted by the same reference numerals throughout the drawings. In the description herein, the reference numerals described above are used as necessary.

Fig. 1 is a diagram showing an elevator including an elevator signal transmission device 30 according to an embodiment. Fig. 2 is a structural diagram of the elevator signal transmission device 30.

The elevator is configured to include a car 11, an elevator drive device 13, and an elevator signal transmission device 30, which are disposed in a hoistway 10 of a building. The car 11 is connected to a counterweight 15 via ropes 14. The elevator driving apparatus 13 is disposed in a machine room 16 and includes a hoisting machine 17. The machine room 16 is disposed on, for example, a roof or an uppermost floor of a building. The ropes 14 are wound around the traction machine 17. The car 11 is raised and lowered in the hoistway 10 by driving of the hoisting machine 17.

The elevator signal transmission device 30 includes an elevator control panel 31, an elevator monitoring panel 40, and a signal path 45 for transmitting a signal between the elevator control panel 31 and the elevator monitoring panel 40. The elevator control panel 31 includes an arithmetic control unit such as a CPU and a storage unit such as a memory. The elevator control panel 31 is disposed in the machine room 16, and includes a control cable transmission unit 32 and an elevator control unit 33. The control cable transmission unit 32 is connected to a relay cable transmission unit 51 of the relay board 50, which will be described later, via a signal cable 60 of a cable system, and transmits and receives signals to and from the relay board 50. The elevator control unit 33 controls the elevator car 11 to ascend and descend by controlling the driving of the elevator driving device 13.

The elevator control unit 33 has a function of causing the elevator to execute a normal operation mode and an abnormal operation mode such as a fire control operation. The "normal operation mode" is a mode intended to be executed by a user moving the car 11 at normal times, and performs call registration in an elevator control unit by operation of a button in the elevator hall or the car 11, and raises and lowers the car 11 in accordance with the call registration. The "abnormal operation mode" is a mode in which the elevator is caused to perform a corresponding abnormal operation when an abnormal control signal such as a signal indicating a fire control operation instruction is input from the elevator monitoring panel 40 to the elevator control panel 31, which will be described later. For example, as the abnormal operation, when a signal indicating a fire control operation instruction is input to the elevator control panel 31, the elevator is caused to perform the fire control operation. In the fire control operation, the elevator control panel 31 controls the elevator drive device 13 to move the car 11 to an evacuation floor such as floor 1, and opens the car door to maintain the car 11 in a stopped state. In this case, the closing of the car 11 may be maintained after the execution of the fire control operation is completed. The signal is transmitted through a tail cable (テールコード)18 between a control panel (not shown) in the car 11 and the elevator control panel 31. In this case, the signal transmission may be performed wirelessly between the control panel in the car 11 and the elevator control panel 31.

The elevator monitoring panel 40 is disposed in the manager room 19 at a position separated from the hoistway 10 in the building. The manager room 19 is disposed on a floor below the floor on which the elevator control panel 31 is disposed in the building, such as the floor 1 or the underground of the building. The elevator monitoring panel 40 includes an arithmetic control unit such as a CPU and a storage unit such as a memory. The elevator monitoring panel 40 includes a monitoring wireless transmission unit 41, a monitoring wired transmission unit 42, an operation unit 43, and a display unit 44. The monitoring wireless transmission unit 41 has a wireless transmission antenna 41a and transmits a wireless signal to a relay board 50 described later. The monitoring cable transmission unit 42 is connected to a relay cable transmission unit 51 of the relay board 50, which will be described later, via a cable-type signal cable 61, and transmits and receives signals to and from the relay board 50. The monitoring wireless transmission unit 41 corresponds to a 1 st wireless transmission unit that transmits wireless signals to and from the relay board 50.

The operation unit 43 is a device for instructing operation of the elevator, such as a key switch or an operation button. For example, a key switch is provided on the elevator monitoring panel 40, and the operation control at the time of a fire, for example, is manually instructed by operating the key switch. At this time, a signal indicating a manual instruction for fire control operation is transmitted from the monitoring wireless transmission unit 41 to the relay wireless transmission unit 52 of the relay panel 50, which will be described later, by a wireless signal. A signal corresponding to the wireless signal is transmitted from the relay wired transmission unit 51 of the relay board 50 to the control wired transmission unit 32 of the elevator control board 31 via the signal cable 60.

The elevator monitoring panel 40 is connected to an automatic fire alarm 62 (fig. 2) of the building through a signal line directly or via a centralized monitoring device (not shown) of the building. When the automatic fire alarm 62 is operated, a signal (fire sensing signal) indicating the operation is transmitted to the elevator monitoring panel 40 as an abnormality detection signal indicating that an abnormality is detected in the building. At this time, the elevator monitoring panel 40 generates a signal indicating an automatic instruction of the controlled operation in the case of fire. The signal indicating the automatic instruction is also transmitted to the relay board 50 as a wireless signal, and is transmitted from the relay board 50 to the elevator control board 31 as a signal corresponding to the wireless signal through the signal cable 60. When a signal indicating a manual instruction or an automatic instruction for the fire control operation is input, the elevator control panel 31 causes the elevator to perform the fire control operation. The configuration in which the signal indicating the command for the operation control in the case of fire is transmitted from the elevator monitoring panel 40 to the elevator control panel 31 in this way can be easily added to existing elevator equipment without such a configuration by an elevator equipment manufacturer as will be described later.

The display unit 44 is a display for displaying the position of the car 11, the operating state of the elevator such as the presence or absence of a failure of the elevator, and the like. For the display of the display unit 44, a signal indicating the elevator operation state is transmitted from the control wire transmission unit 32 of the elevator control panel 31 to the relay wire transmission unit 51 of the relay panel 50 via the signal cable 60. Then, the signal is transmitted from the relay cable transmission unit 51 to the monitoring cable transmission unit 42 of the elevator monitoring panel 40 via the signal cable 61. The elevator monitoring panel 40 displays the operation state indicated by the signal transmitted to the monitoring cable transmission unit 42 on the display unit 44. In the case where there are a plurality of cars, the operating state of each car can be displayed on the display unit 44.

The signal path 45 between the elevator control panel 31 and the elevator monitoring panel 40 includes the above-described signal cables 60 and 61, a relay panel 50 described later, and a wireless signal path 63 (fig. 2).

The relay panel 50 is provided in the middle of the signal path 45 between the elevator monitoring panel 40 and the elevator control panel 31, and is disposed at, for example, 1 floor in the hoistway 10. The relay board 50 has a relay wired transmission unit 51 and a relay wireless transmission unit 52. The relay cable transmission unit 51 is connected to a signal path between the monitoring cable transmission unit 42 and the control cable transmission unit 32. The relay wireless transmission unit 52 has a wireless receiving antenna 52a, and receives a wireless signal such as a signal indicating a fire control operation instruction transmitted from the monitoring wireless transmission unit 41 of the elevator monitoring panel 40. The relay radio transmitter 52 corresponds to a 2 nd radio transmitter that transmits a radio signal to and from the monitoring radio transmitter 41. In the present specification and claims, "transmission" includes a meaning of only transmission, only reception, or transmission and reception. The information indicated by the wireless signal is converted into a wired signal by the relay board 50, and is transmitted from the relay wired transmission unit 51 to the control wired transmission unit 32 of the elevator control panel 31 via the signal cable 60.

The wireless signal path 63 (fig. 2) is a signal path between the monitoring wireless transmission unit 41 of the elevator monitoring panel 40 and the relay wireless transmission unit 52 of the relay panel 50. In fig. 2, the wireless signal path 63 is shown by a dotted line. Thus, in the signal path 45 for transmitting signals between the elevator monitoring panel 40 and the elevator control panel 31, a part of the signal path outside the hoistway 10 is wireless.

According to the elevator signal transmission device 30, when a new type of signal is transmitted between the elevator monitoring panel 40 and the elevator control panel 31, it is possible to prevent a disconnection due to deterioration of a signal line while suppressing an increase in cost of an elevator facility manufacturer. For example, as an existing device, there is a case where the elevator monitoring panel 40 and the relay panel 50 are connected by a wired signal cable 61, and a configuration in which a signal indicating a fire control operation instruction is transmitted from the elevator monitoring panel 40 to the elevator control panel 31 is not provided. In this case, according to the embodiment, it is easy for the elevator equipment manufacturer to add a configuration for wirelessly transmitting the signal from the monitoring wireless transmission unit 41 to the relay wireless transmission unit 52 to the existing equipment. Specifically, there is no need to newly add a signal cable in a wired manner between the elevator monitoring panel 40 and the relay panel 50. This eliminates the need to add a signal cable outside the hoistway 10, thereby suppressing an increase in cost for the elevator equipment and preventing disconnection due to deterioration of the signal cable. On the other hand, many signal cables are arranged outside the hoistway 10 in the building, and the arrangement work is performed by an electric construction company. Therefore, it is difficult for the elevator equipment provider to completely grasp the arrangement position of the existing signal cable, and when a new signal cable is added by the elevator equipment provider, it is necessary to newly wire the signal cable whose arrangement position is unknown. According to the present embodiment, since there is no need to add a new signal cable, it is easy for an elevator facility manufacturer to add a configuration for wirelessly transmitting a new type of signal from the monitoring wireless transmission unit 41 to the relay wireless transmission unit 52 to an existing facility. On the other hand, a part of the signal cable 60 between the relay board 50 and the elevator control board 31 is disposed in the hoistway 10, but the signal cable is disposed by an elevator equipment company. Therefore, even when a new signal cable is added between the relay board 50 and the elevator control board 31 in accordance with a configuration in which a new type of signal is wirelessly transmitted between the elevator monitoring board and the relay board, the elevator equipment can easily perform the additional operation.

Further, the signal cable 61 connected to the monitoring cable transmission unit 42 and the monitoring cable transmission unit 42 of the elevator monitoring panel 40 may be detached, and the signal path between the elevator monitoring panel 40 and the relay panel 50 may be wirelessly changed. In the above description, the case where the signal is wirelessly transmitted from the elevator monitoring panel 40 to the relay panel 50 is described. On the other hand, in the case where a configuration is added in which a new type of signal is transmitted from the elevator control panel 31 to the elevator monitoring panel 40, a function of wirelessly transmitting the signal from the relay wireless transmission unit 52 to the monitoring wireless transmission unit 41 may be added. In this case, the relay wireless transmission unit 52 is provided with a wireless transmission antenna, and the monitoring wireless transmission unit 41 is provided with a wireless reception antenna.

In the above description, the case where the abnormal-state control signal indicating the fire-state control operation instruction is transmitted from the elevator monitoring panel 40 to the elevator control panel 31 has been described. On the other hand, another type of abnormal-state control signal may be transmitted from the elevator monitoring panel 40 to the elevator control panel 31. For example, the following structure is also possible: when a gas leakage detection signal is input from a gas leakage sensor in the building to the elevator monitoring panel 40, an abnormal time control signal indicating a gas leakage time control operation instruction is transmitted from the elevator monitoring panel 40 to the elevator control panel 31. In addition, when the specification of the monitoring panel is changed, for example, by attaching a new switch to the elevator monitoring panel, a new type of signal needs to be transmitted between the monitoring panel and the elevator control panel. In this case, the signal may be transmitted wirelessly between the elevator monitoring panel 40 and the relay panel 50 or between the elevator monitoring panel 40 and the elevator control panel 31.

The above describes the case where the relay board 50 is one. On the other hand, when the length of the hoistway 10 is long, or the like, a plurality of relay boards may be disposed on different floors in the hoistway 10. In this case, the relay panel located at the lowermost layer among the plurality of relay panels may be connected to the elevator monitoring panel 40 through a wireless signal path, and a signal path including another relay panel may be connected to the elevator control panel 31 through a wired line. In this case, the signal path between the plurality of relay boards may be wireless. The relay panel may be omitted, and the signal path between the elevator monitoring panel 40 and the elevator control panel 31 may be connected wirelessly.

In the above description, the elevator control panel 31 is disposed in the roof of the building or in the machine room located at the uppermost floor or the like, and the elevator monitoring panel 40 is disposed on the floor lower than the floor on which the elevator control panel 31 is disposed in the building. On the other hand, the present invention is not limited to this, and the elevator monitoring panel may be disposed in a space different from the space in which the elevator control panel is disposed in the building and at a position different from the floor below the floor on which the elevator control panel is disposed. For example, the elevator control panel may be disposed in the vicinity of a bottom portion called a pit in a space in the hoistway 10 of the building or above the pit in the space in the hoistway 10. In this case, the elevator monitoring panel may be disposed in a space other than the hoistway 10, for example, in a space of the manager room 19 located at a position separated from the hoistway 10 in the building. In this case, at least a part of the signal path outside the hoistway 10 among the signal paths for transmitting signals between the elevator monitoring panel and the elevator control panel is made wireless, whereby the same effects as those of the elevator signal transmission device 30 of the above embodiment can be obtained. In this case, as in the elevator signal transmission device 30 of the above embodiment, the following configuration may be adopted: the signal path includes a relay board in the hoistway 10, the elevator monitoring board includes a monitoring wireless transmission unit as a 1 st wireless transmission unit, and the relay board includes a relay wireless transmission unit as a 2 nd wireless transmission unit. In addition, the 1 st wireless transmission unit and the 2 nd wireless transmission unit in the signal path may be connected wirelessly to connect the relay panel and the elevator control panel by wire or wirelessly. The elevator monitoring panel may be configured to receive an abnormality detection signal indicating that an abnormality is detected in the building.
