Design Of Short-range Wireless Measurement And Control System

Crane is essential lifting equipment , which is used in a modern industrial enterprises, transportation and infrastructure sectors. It is used to enhance and move up bulky goods; also used in assembly machines in large-scale factory floor and production processes. used to reduce heavy manual workers and improve labor productivity.Bridge crane from one or two main beam and two side constitute a bridge beam. The bridge is equipped with lifting trolley, trolley running along the bridge. Bridge in the plant set up to run track, but also can run in the open air on the trestle. Bridge crane, also known as "traffic" .Some of the rail cargo in the open-air installation of overhead traveling crane for loading and unloading heavy cargo major, it in two rows of reinforced concrete bridge. Along the bridge crane on the track for vertical dynamic shift.Crane lifting trolley car at the bridge on the track for lateral movement, this fight on the hook or in a rectangular space for take-off and landing at any location, removal of the movement object.Bridge gantry cranes are used in many simple mechanical devices to achieve the limit function of touch, Mechanical touch devices prone to frequent collision deformation, limit the loss of function, resulting in dramatic crane collisions between moving parts, premature to make a crane damage, and endanger the safety of production, resulting in major economic losses. I made use of short-range wireless transmission, limit the establishment of a new measurement and control system. through the use of the functional integrity of the RF system-on-chip wireless transceiver modules to build NRF9E5, application of the wireless transceiver modules, Hall proximity switches and solid-state relays, limit the development of the wireless communications monitoring and control systems, in order to achieve close to the police to control the load power features such as on-off limit. Complete system hardware design: Limit wireless sensor nodes and control circuit design; Completion of the system software design : Initialization procedures and the procedures to send and receive. Achieve the system.
