Problems solved by technology

There is a sudden increase in the wire diameter of the cable at the connecting device. When winding the emergency lighting cable, the above-mentioned wire diameter changes, making it difficult for the cable to pass through some existing follower devices, resulting in real-time winding of the cable. Difficulty measuring length
During the cable winding process, the radius formed by the cable on the cable reel also changes continuously with the winding and unwinding, which also increases the difficulty of measurement to a certain extent.

Abstract

The invention discloses an emergency lighting cable pay-off and take-up length measuring device which comprises a reel controller, a cable reel and a winding displacement device. The reel controller controls rotation of the cable reel, a pulse identifier for identifying the rotation turn numbers of the cable reel is arranged on the cable reel, a proximity switch for identifying the pulse identifier is arranged on one side or two sides of the cable reel, position switches are arranged at two ends of the winding displacement device, both the proximity switch and the position switches are connected with the reel controller, and the reel controller is connected with a display module. The emergency lighting cable pay-off and take-up length measuring device gives consideration to the influence on the pay-off and take-up length of different layer numbers during winding, so that the cable pay-off and take-up length measurement is accurate. The influence on the measurement of cable diameter change caused by cable connection is eliminated, and the device is suitable for multiple-section cable connection. By combining a simple position detecting device and a proposed computing method, the cable length can be accurately measured in real time. The position detection of the reel is achieved by utilizing reinforcing ribs or detection holes of the cable reel, and the costs of the device are reduced.

Description

technical field [0001] The invention relates to a device and method for measuring the retractable length of an emergency lighting cable. Background technique [0002] The emergency lighting cable is made of multiple wires connected to the required length through the connecting device. There is a sudden increase in the wire diameter of the cable at the connecting device. When winding the emergency lighting cable, the above-mentioned wire diameter changes, making it difficult for the cable to pass through some existing follower devices, resulting in real-time winding of the cable. Length measurement is difficult. During the cable winding process, the radius formed by the cable on the cable reel also changes continuously with the winding and unwinding, which also increases the difficulty of measurement to a certain extent. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, to provide a device and method for measuring the ...
