Non-contact distance early warning device suitable for elevators

Abstract

The invention discloses a non-contact distance early warning device suitable for an elevator. The non-contact distance early warning device suitable for the elevator comprises a collection display module, an encoder for receiving a segment code signal output by the collection display module, a singlechip connected with the encoder, and a display terminal used for receiving signals of the single-chip microcomputer; the collection display module is placed on the display module of the elevator in an overlapping manner, and comprises a plurality of photosensitive diodes arranged on a back side and in the same positions of the self display elements of the elevator, and a plurality of light emitting diodes arranged on a front side and in positions corresponding to the photosensitive diodes. The non-contact distance early warning device suitable for elevators has the beneficial effects as follows: the early warning device provided by the invention adopts a photoelectric conversion technology, can remotely and reliably monitor the operational parameters and the running states of the elevator, and provides an effective mean for improving the security and the reliability of the elevator, and the early warning device, as a third party, is completely isolated from the self control system of the elevator, and cannot influence the self running of the control system of the elevator.

Description

technical field [0001] The invention relates to an early warning device, in particular to a non-contact remote early warning device suitable for elevators, belonging to the field of elevators. Background technique [0002] With the development of the economy and the continuous expansion of the city, the number of high-rise residential buildings is increasing, and the number of elevators installed and used is also increasing. As of the end of 2012, the total number of elevators in use in the country has reached more than 2 million units, and it is growing at a rate of about 20% per year, and the number of new elevators is more than 300,000 units each year. However, when the use of elevators brings convenience to people's access, casualties and economic losses caused by elevator failures are also increasing. According to incomplete statistics, in 2010 Guangzhou 110 received an average of about 50 calls for help with elevators per month, Qingdao had more than 50 complaints abo...
