本発明は、エレベータ側に配置される遠隔監視装置と、エレベータから離れた場所に配置される監視センタ装置とを無線通信機及びアンテナを介して通信させるようにしたエレベータの遠隔監視システムに関する。 The present invention relates to an elevator remote monitoring system in which a remote monitoring device arranged on an elevator side and a monitoring center device arranged at a location distant from the elevator are communicated via a radio communication device and an antenna.
この種の従来技術が特許文献１に開示されている。この特許文献１に開示された従来技術は、エレベータ側に配置される遠隔監視装置と、エレベータから離れた場所に配置され、エレベータを監視する監視センタ装置との間の監視情報の送受信を、乗場の位置表示器内に設けた無線通信機とアンテナとを介して無線通信するようにしたものである。 This type of prior art is disclosed in Patent Document 1. The prior art disclosed in this Patent Document 1 transmits and receives monitoring information between a remote monitoring device arranged on the elevator side and a monitoring center device arranged at a location away from the elevator and monitoring the elevator, Wireless communication is performed via a wireless communication device provided in the position indicator and an antenna.
しかしながら、前述した特許文献１に開示された従来技術では、乗場の位置表示器内にアンテナ及び無線通信機を設置するので、無線通信機からエレベータの昇降路内の遠隔監視装置までの配線が長くなり、配線の敷設に要する作業時間が長くなる問題がある。 However, in the prior art disclosed in Patent Document 1 described above, the antenna and the wireless communication device are installed in the position indicator of the hall, so that the wiring from the wireless communication device to the remote monitoring device in the elevator hoistway is long. Therefore, there is a problem that the work time required for laying the wiring becomes long.
このようなことから、配線を短くするために無線通信機及びアンテナを昇降路内に配置された遠隔監視装置付近に設置し、無線通信機と遠隔監視装置との距離を近づけるようにすることが考えられる。しかし、このように構成した場合、エレベータの乗かごが停止する高さ位置に無線通信機のアンテナが設置されている場合には、停止している乗かごによってアンテナから送受信される電波が遮断され、通信状況が低下して監視情報の送受信の精度が低下してしまうことになる。 For this reason, in order to shorten the wiring, it is possible to install a wireless communication device and an antenna near the remote monitoring device arranged in the hoistway so that the distance between the wireless communication device and the remote monitoring device is reduced. Conceivable. However, in this configuration, when the antenna of the wireless communication device is installed at a height position where the elevator car stops, radio waves transmitted and received from the antenna are blocked by the stopped car. As a result, the communication status is lowered and the accuracy of sending and receiving the monitoring information is lowered.
本発明は、前述した従来技術における実情からなされたもので、その目的は、無線通信機と遠隔監視装置とを接続する配線を短くすることができ、また、停止した乗かごに影響を受けることなく遠隔装置と監視センタ装置との間で、良好な無線通信を実現させることができるエレベータの遠隔監視システムを提供することにある。 The present invention has been made from the actual situation in the prior art described above, and its purpose is to shorten the wiring connecting the wireless communication device and the remote monitoring device, and to be affected by the stopped car.

前述したアンテナは、互いに乗かご２の高さ寸法よりも大きい高さ方向の距離だけ離隔させて配置した複数のアンテナ、例えば第１アンテナ６１と第２アンテナ６２とから成っている。 The antenna described above includes a plurality of antennas, for example, a first antenna 61 and a second antenna 62, which are arranged apart from each other by a distance in the height direction larger than the height dimension of the car 2.
また、昇降路１から離れた位置に基地局８が設置され、この基地局８にはアンテナ７が設けられている。基地局８は、回線網９を経由して、エレベータを遠隔的に監視する監視センタ装置１０に接続されている。 A base station 8 is installed at a position away from the hoistway 1, and an antenna 7 is provided in the base station 8. The base station 8 is connected via a network 9 to a monitoring center device 10 that remotely monitors the elevator.
また、本実施形態は、第１アンテナ６１と第２アンテナ６２のうちのそれぞれの電波強度を計測する電波強度測定部４１と、遠隔監視装置４が監視センタ装置１０に通報する際に、電波強度測定部４１で測定された第１アンテナ６１、第２アンテナ６２のうちの最も強い強度を有するアンテナを選択するアンテナ選択部４２を備えている。電波強度測定部４１とアンテナ選択部４２は、例えば遠隔監視装置４に設けてある。 Further, in the present embodiment, the radio wave intensity measurement unit 41 that measures the radio wave intensity of each of the first antenna 61 and the second antenna 62 and the radio wave intensity when the remote monitoring device 4 reports to the monitoring center device 10. An antenna selection unit 42 that selects the antenna having the strongest strength among the first antenna 61 and the second antenna 62 measured by the measurement unit 41 is provided. The radio wave intensity measurement unit 41 and the antenna selection unit 42 are provided in the remote monitoring device 4, for example.
なお、遠隔監視装置４は、制御装置３から出力される制御信号の異常の有無を検出する異常監視部４４と、この異常監視部４４で異常が検出されたとき、無線通信機５に無線通信を指示する通信部４３とを備えている。 The remote monitoring device 4 detects an abnormality in the control signal output from the control device 3, and when the abnormality monitoring unit 44 detects an abnormality, the remote monitoring device 4 performs wireless communication with the wireless communication device 5.

このように構成した本実施形態は、前述したように、遠隔監視装置４の異常監視部４４が制御装置３から出力される制御信号の異常を検出したとき、通信部４３から無線通信機５に無線通信の指示が行われるが、このとき、アンテナ選択部４２は、第１アンテナ６１、第２アンテナ６２のうちの強い電波強度を有する方のアンテナを選択するように無線通信機５に指示する。したがって、無線通信機５は、アンテナ選択部４２によって選択された強い電波強度を有するアンテナを使用し、そのアンテナと基地局８と回線網９を経由して、監視センタ装置１０に異常通報を行う。 In the present embodiment configured as described above, when the abnormality monitoring unit 44 of the remote monitoring device 4 detects an abnormality in the control signal output from the control device 3 as described above, the communication unit 43 transmits the abnormality to the wireless communication device 5. An instruction for wireless communication is performed. At this time, the antenna selection unit 42 instructs the wireless communication device 5 to select one of the first antenna 61 and the second antenna 62 having the stronger radio wave intensity. . Therefore, the wireless communication device 5 uses the antenna having the strong radio field intensity selected by the antenna selection unit 42, and notifies the monitoring center device 10 of the abnormality via the antenna, the base station 8, and the network 9. .
本実施形態によれば、無線通信機５に接続される第１アンテナ６１及び第２アンテナ６２を、遠隔監視装置４が配置される同じ昇降路１内に設け、第１アンテナ６１及び第２アンテナ６２と、無線通信機５とを遠隔監視装置４付近に設けたことから、無線通信機５と遠隔監視装置４とを接続する配線を短くすることができる。これにより配線の敷設作業を短時間で済ませることができる。 According to the present embodiment, the first antenna 61 and the second antenna 62 connected to the wireless communication device 5 are provided in the same hoistway 1 where the remote monitoring device 4 is disposed, and the first antenna 61 and the second antenna are provided. Since 62 and the wireless communication device 5 are provided in the vicinity of the remote monitoring device 4, the wiring connecting the wireless communication device 5 and the remote monitoring device 4 can be shortened. As a result, the wiring laying operation can be completed in a short time.
また、本実施形態に備えられる第１アンテナ６１と第２アンテナ６２は、互いに乗かご２の高さ寸法よりも大きい高さ方向の距離だけ離隔させて配置したアンテナであることから、アンテナ選択部４２で選択された第１アンテナ６１及び第２アンテナ６２のうちのいずれかのアンテナは、停止した乗かごに影響されない電波強度測定部４１で測定された強い電波強度を有する方のアンテナであり、このアンテナを介して遠隔監視装置４と監視センタ装置１０との間で精度の高い送受信を行わせることができる。すなわち本実施形態は、アンテナを昇降路１内に配置したにも拘わらず、停止した乗かご２による悪影響を受けることなく、信頼性の高い無線通信を実現させることができる。 Further, since the first antenna 61 and the second antenna 62 provided in the present embodiment are antennas that are spaced apart from each other by a distance in the height direction that is larger than the height dimension of the car 2, the antenna selection unit Any one of the first antenna 61 and the second antenna 62 selected in 42 is an antenna having a strong radio field intensity measured by the radio field intensity measurement unit 41 that is not affected by the stopped car. High-accuracy transmission / reception can be performed between the remote monitoring device 4 and the monitoring center device 10 via this antenna. That is, this embodiment can realize highly reliable wireless communication without being adversely affected by the stopped car 2 even though the antenna is arranged in the hoistway 1.
なお、乗かご２が通常走行中に異常を検出して遠隔監視装置５から通報するときには、走行中の乗かご２が通信障害となって通信エラーが発生することがあるが、このような場合でも、遠隔監視装置５は異常通報を再送する機能を有するものであるので、乗かご２の走行中の異常通報を実施することができる。 Note that when the car 2 detects an abnormality during normal traveling and reports from the remote monitoring device 5, the traveling car 2 may become a communication failure and a communication error may occur. However, since the remote monitoring device 5 has a function of retransmitting the abnormality report, the abnormality report while the car 2 is traveling can be performed.
また、前述した実施形態にあっては、電波強度測定部４１及びアンテナ選択部４２を遠隔監視装置４に設けた構成にしてあるが、本発明は、このように構成することには限られない。電波強度測定部４１及びアンテナ選択部４２を、無線通信機５に設けた構成にしてもよい。 In the embodiment described above, the radio field intensity measurement unit 41 and the antenna selection unit 42 are provided in the remote monitoring device 4, but the present invention is not limited to such a configuration. . The radio wave intensity measuring unit 41 and the antenna selecting unit 42 may be provided in the wireless communication device 5.
