Different-rail lifting anti-collision protection device and method based on UWB

Abstract

The invention discloses a different-rail lifting anti-collision protection device and method based on an UWB. The device comprises an UWB base station, an WUB label and an anti-collision control module; a power supply module and the anti-collision control module electrically connected are arranged in a control circuit sealing box; the UWB label is mounted on lifting machinery; the UWB base stationis arranged in anti-collision points of two sides of the lifting machinery or another lifting machinery; and the anti-collision control module comprises a main controller, and a signal display circuit, a RS422 communication circuit, a sound-light alarm circuit, an anti-collision control circuit and a remote output circuit electrically connected with the main controller. The different-rail liftinganti-collision protection device and method based on the UWB adopt different grades of alarm and lifting machinery motor deceleration and braking modes to realize the anti-collision safety work of the lifting machinery.

Description

technical field [0001] The invention belongs to the technical field of crane control and protection devices, and in particular relates to a UWB-based non-same-track lifting anti-collision protection device and method. Background technique [0002] In industrial control, the crane anti-collision device is an important device to protect the safe operation of hoisting machinery. The main characteristics of the crane anti-collision devices put into use at home and abroad are: the protection device can only be installed on the crane on the same track; most crane anti-collision devices use photoelectric switches or laser and infrared ranging sensors as the anti-collision protection For the signal generation unit, the setting of the alarm distance is complicated and the error is large, and the transmitting and receiving devices must be cleaned regularly, and the installation and maintenance are cumbersome. Some crane anti-collision instruments use microwave technology to detect th...

The main characteristics of the crane anti-collision devices put into use at home and abroad are: the protection device can only be installed on the crane on the same track; most crane anti-collision devices use photoelectric switches or laser and infrared ranging sensors as the anti-collision protection For the signal generation unit, the setting of the alarm distance is complicated and the error is large, and the transmitting and receiving devices must be cleaned regularly, and the installation and maintenance are cumbersome

Some crane anti-collision instruments use microwave technology to detect the distance between the hoisting machinery and obstacles through microwaves. This type of crane anti-collision instrument uses a non-contact method to achieve distance detection, which can avoid errors caused by long-term use, but Long-distance microwave anti-collision sensors are expensive and mostly imported complete sets of products, with long maintenance cycles and low cost performance
