A control method based on wireless communication for adding and uncapping the lid of molten iron tank

Abstract

The invention relates to a hot metal bottle lid capping and uncovering device control method based on wireless communication. A hot metal ladle capping and uncovering control system based on wirelessEthernet communication is firstly established. The system comprises an on-vehicle control box installed on a hot metal bottle vehicle, on-vehicle operating boxes A and B, a power supply pile, a station control cabinet, a control room HMI computer and a hot metal ladle capping and uncovering device installed on the hot-metal bottle vehicle. The method comprises the following steps of using the station control cabinet or an HMI operating power supply pile to provide power for equipment on the hot metal bottle vehicle; and on the hot-metal bottle vehicle, through the on-vehicle control box, selecting a remote/on-site switch, wherein if the remote switch is selected, a control room HMI remotely controls the operation of hot metal ladle capping and uncovering, and if the on-site switch is selected, the on-vehicle control box completes the hot metal ladle capping and uncovering. In the invention, Remote operation means at a safety position can be provided for the control of the hot metal ladle capping and uncovering, and when the hot metal bottle vehicle arrives at a station, concentration monitoring can be immediately performed and the operation of rapid capping and uncovering is realized. By using the method, operation is simple and high-efficient, and safety is high.

Description

technical field The present invention relates to a method for controlling a device for adding and removing lids of molten iron tanks based on wireless communication, in particular to a method of using wireless Ethernet to implement equipment installed on molten iron tankers and power supply piles at the station near the vehicle end of the molten iron tanker parking station. The wireless communication between the station control cabinet at the remote train end and the HMI computer in the control room, and the PLC controller installed in the train control box and station control cabinet to realize the remote detection and control of the equipment to complete the ladle on the molten iron tanker A control method for capping and uncapping operations. Background technique The molten iron tanker is a special platform used for metallurgical enterprises to transport molten iron to the cast iron machine for pouring iron blocks or to the steelmaking workshop to inject the molten iron i...
