Description

Technical Field

[0001] The utility model belongs to the technical field of monorail crane control, and in particular relates to a monorail crane control device based on the ZigBee technology. Background Art

[0002] Monorail crane is an auxiliary transportation equipment running on the suspended monorail system with strong mobility, fast running speed, large load capacity, safety and reliability. It is mainly used to transport materials, equipment and personnel up and down the mountain in the mining area and in the horizontal tunnel of the working face. At present, the wireless communication equipment in the monorail crane transportation system mainly includes remote control device, switch device and sound and light alarm device. The main problems are:

[0003] (1) Each device is independent, and the wireless signals and communication protocols are different. There is a lot of data redundancy, which reduces database performance and increases the complexity of data management.

[0004] (2) Since the monorail crane itself is long, up to 30 meters or more, and the remote control receiver is installed near the electric control box, that is, in the middle of the monorail crane, it is also affected by factors such as the ups and downs of the lane, turns, and metal device obstruction. When the driver operates at both ends of the locomotive, the remote control is often interrupted. During the operation of the monorail crane locomotive, the sound and light alarm in the lane along the monorail crane locomotive is required to remind nearby personnel to avoid it. Remote control delay or interruption not only reduces work efficiency, but also poses a safety hazard;

[0005] (3) At present, there are two types of turnout devices: manual and driver-controlled. When the driver remotely controls the locomotive to drive to the manual mode of the turnout device, he needs to stop the car and manually move the turnout, and confirm that the turnout is in place before continuing to remotely control the locomotive. The driver-controlled turnout can move the turnout remotely, but currently the turnout remote control and locomotive remote control are operated independently. The driver needs to hold two remote controls, which is very inconvenient and prone to errors. Utility Model Content

[0006] The purpose of the utility model is to provide a monorail crane control device based on ZigBee technology to solve the problems of each device being independent, wireless signals and communication protocols being different, the monorail crane itself being long, being affected by factors such as tunnel undulations, turns, and obstruction by metal devices, remote control delays or interruptions, and the inconvenience of using multiple remote controllers.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A monorail crane control device based on ZigBee technology comprises a host receiver, a router receiver, a switch controller, a handheld remote controller and an audible and visual alarm. Each device is equipped with a ZigBee wireless communication module. The monorail crane comprises a locomotive and a lifting beam. The host receiver is installed at the front end of the monorail crane and can be operated by connecting a 12V intrinsically safe power supply. The host receiver is connected to the locomotive through a CAN bus. The electric control system of the locomotive is connected to the lifting beam through the CAN bus. The host receiver controls the movement, parking, whistle and lifting of the locomotive. The host receiver is wirelessly connected to the audible and visual alarm and the handheld remote controller.

[0009] The router receiver is installed at any position of the locomotive or lifting beam of the monorail crane, and can be operated by connecting to a 12V intrinsically safe power supply. It is wirelessly connected to the host receiver and functions as a relay, forwarding the information sent by the handheld remote control and the sound and light alarm to the host receiver.

[0010] The zigbee wireless communication module of the switch controller is set as a router to send switch status data to the monorail crane host receiver; the switch controller receives the control command of the handheld remote control, controls the switch quantity according to the command to close the solenoid valve, and controls the switch action.

[0011] The sound and light alarm is connected to a DC12V intrinsically safe power supply. When a monorail crane approaches, a host receiver of the monorail crane is connected to the network of the sound and light alarm, and the sound and light alarm sends out an alarm signal to prompt the monorail crane to pass by.

[0012] The handheld remote controller is used to send information to the host receiver and the switch controller to control the monorail crane and the switch action.

[0013] The handheld remote controller is equipped with a zigbee low-power terminal, powered by a battery with a voltage of 4.5V, equipped with an LCD display to display locomotive operation data and error codes, and wirelessly connected to the locomotive and turnout controller through a zigbee wireless communication module. The handheld remote controller operates with low power consumption and sends heartbeat data to the locomotive every 5 seconds to transmit locomotive information and ensure that the locomotive and the remote controller are connected.

[0014] The number of the router receivers is greater than or equal to 3.

[0015] Beneficial effects achieved by the utility model:

[0016] (1) The device integrates the wireless devices in the operation of the monorail crane, unifies the wireless signal type and data structure, and makes it a local area network. Any device in the network is not restricted by space and can communicate freely, ensuring smooth communication of the monorail crane and the stability of the alarm signal. The switch device promptly feedbacks the switch status to ensure the safety of the monorail crane operation and reduce safety hazards.

[0017] (2) Reduce the number of settings for handheld remote controls, making them easier to use and less prone to errors. BRIEF DESCRIPTION OF THE DRAWINGS
