Problems solved by technology

[0003] This kind of operation structure often has the following defects: 1. There is a lot of dust on site, and the belt speed detector keeps rubbing the belt to reduce its life, frequent replacement costs are high, and the effective working time is reduced; 2. The ship unloader travels to the belt At the tail of the machine, due to the gap between the belt conveyor belt and the belt speed detector, the belt speed detector hardly works, and the control system cannot receive accurate signals, sometimes even causing safety hazards

Abstract

The invention relates to auxiliary devices and methods of a ship unloader control system, in particular to a belt conveyor signal transmission control device and method used for a ship unloader. The belt conveyor signal transmission control device comprises wireless communication devices and an exchange device (2) and is characterized in that the wireless communication devices are a wireless transmitter (5) and a wireless receiver (6) which correspond to each other, the wireless transmitter is connected to a belt conveyor PLC (4) through a signal transmission line (3), the wireless receiver is connected with the exchange device through a signal transmission line, and the exchange device is connected to a ship unloader PLC (1). The belt conveyor signal transmission control device and method have the advantages of being accurate, efficient, low in failure rate and service life of the device is prolonged.

Description

technical field [0001] The invention relates to an accessory device and a method of a ship unloader control system, in particular to a transmission control device and a control method of a belt conveyor signal for a ship unloader. Background technique [0002] For a long time, the vibrating feeders of ship unloading equipment used in most ore terminals at home and abroad have obtained signals by using the belt speed detector installed under the ship unloader to detect the operation status of the belt conveyor. The belt speed detector The friction belt obtains the running signal of the belt conveyor, and then transmits the signal to the PLC control system of the ship unloader to control the operation of the vibrating feeder mechanism of the ship unloader. [0003] This kind of operation structure often has the following defects: 1. There is a lot of dust on site, and the belt speed detector keeps rubbing the belt to reduce its life, frequent replacement costs are high, and th...
