Electric hoist based on Android system

Abstract

The invention relates to an electric hoist based on an Android system. The electric hoist based on the Android system comprises an electric hoist body, an output device, a WIFI control module, an Android device and a programmable controller, the Android device is connected with the WIFI control module through a WIFI wireless local area network, the programmable controller is connected with the WIFI control module, the output device is connected with the programmable controller, and the electric hoist body is connected with the output device. By means of the design, firstly, a control signal can be emitted by the Android device, the control signal is transmitted through a MODBUS protocol and transmitted to the programmable controller through the WIFI wireless local area network established by the WIFI control module, and the control signal is analyzed by the programmable controller through the MODBUS protocol; then, the control signal is transmitted to the output device, and the output device drives the electric hoist body to complete motions such as walking and lifting.

Description

technical field [0001] The invention relates to an electric hoist, in particular to an electric hoist based on an Android system. Background technique [0002] At present, the electric hoist is a kind of special equipment. Generally, its control circuit is composed of handle, relay, contactor and other components. The wiring is complicated, the failure rate is high, and the reliability is poor. During the long-term use of the control handle, the contacts are easily oxidized, which leads to easy Poor contact, often being dropped or smashed, the casing is damaged, and the internal live parts are exposed, causing potential safety hazards; in addition, the traditional handle is connected with a long control cable, which is very inconvenient to use, and the cable is easily damaged and broken during long-term movement; and often Non-professionals use it at will, which also brings a lot of security risks. Although some electric hoists are controlled by industrial remote control, t...

Problems solved by technology

[0002] At present, the electric hoist is a special equipment. Generally, its control circuit is composed of handles, relays, contactors and other components. The wiring is complicated, the failure rate is high, and the reliability is poor; Poor contact, often being dropped or smashed, resulting in damage to the shell, and exposure of internal live parts, causing safety hazards; in addition, the traditional handle is connected to a long control cable, which is very inconvenient to use, and the cable is easily damaged and broken during long-term movement; and often There are non-professionals who use it at will, which also brings a lot of potential safety hazards

Although some electric hoists are controlled by industrial remote controllers, their handles also have the above-mentioned safety problems of being easy to fall and break and cannot prevent non-professionals from using them.
