Problems solved by technology
Therefore, under the influence of the operation sound of the hoist, the abnormality detection device cannot detect abnormalities of other equipment, and when abnormal noises are generated by equipment other than the hoist, the abnormality detection device cannot be detected due to the influence of the abnormal sound. Correctly judge the operating status of the hoist, which makes the maintenance and inspection confusing

An elevator abnormity detector can correctly detect the abnormity of a plurality of devices according to the operation sound. The elevator abnormity detector is equipped on the elevator, picks up the operation sound of the devices through a sound picking-up microphone, and furthermore detects the abnormity through analyzing the characteristic of the operation sound. The elevator comprises the following components: a hoister (6) which is used for driving an elevator cage (1) and a counterweight (2) which are set to lift in a lifting passage (4); elevator doors (8a-8c, 9) which are respectivelyequipped at the side of the elevator cage (1) and the outlets (1a, 7a-7c) of the elevator hall side and causes the free passing in and out of the passenger from the elevator cage (1) through the opening and closing of the elevator door. In the elevator abnormity detector, the sound picking-up microphones (10a-10g) are respectively equipped in the vicinity of the hoister (6), the vicinity of the inlets / outlets (7a-7c) and a plurality of positions in the lifting passage (4) so that the abnormity of the plurality of devices can be detected out.
Description
technical field [0001] The invention relates to an elevator anomaly detection device, which analyzes the sound characteristics of the equipment by arranging a sound pickup microphone near the equipment, so as to detect whether there is an abnormality. Background technique [0002] As an existing elevator abnormality detection device, for example, a solution is disclosed in Patent Document 1, which is provided with a pickup microphone on the top of the elevator car and inside the elevator car. The sound pickup microphone on the top and inside the elevator car picks up the sound, and judges whether the elevator can run or not according to the size of the sound (for example, refer to Patent Document 1). [0003] In addition, in terms of an abnormal detection device for an elevator without a machine room, for example, a solution is disclosed in Patent Document 2, which installs a sound pickup microphone integrally formed with a camera near the hoist, and makes the hoist operate ...
