technical field

The utility model relates to a remote operation control of a coal mining machine, in particular to a novel remote control system of a coal mining machine.

Background technique

At present, there are three modes of remote control operation of coal mining machines: mode 1, wireless operation based on radio waves; mode 2, wired operation mode directly connected to the main controller of the coal mining machine; mode 3, comprehensive operation of mode 1 and mode Way. All three methods of remote operation have disadvantages. Method 1 has two disadvantages: 1. The remote operation method is single. 2. The radio wave transmission environment in coal mines is complex, which makes the reliability of signal transmission poor, and misoperation and operation failure will occur. Method 2 also has two disadvantages: 1. Remote control The operation mode is single, 2. The operation signal of this operation mode is directly input to the main controller of the shearer, which will bring noise interference to the main controller of the shearer and affect the normal operation of the shearer; the third mode exists in the second mode Point 2 falls short.

The utility model includes a wireless operation transmitter, a wired operation hand-held device and a remote control signal receiving device. The remote control signal receiving device is installed inside the coal mining machine. The remote control signal receiving device includes a wireless receiving module and a wired receiving module. The signal is connected to the wireless receiving module of the remote control signal receiving device, the wired operation handheld is connected to the wired receiving module of the remote control signal receiving device through a bus cable, and the remote control signal receiving device is connected to the main controller of the coal shearer through an output interface and a connecting cable.

Further, the wireless operation transmitter and the wired operation handheld are isolated from the main controller of the coal mining machine through the remote control signal receiving device.

Further, the CAN bus is used between the wired receiving module and the wired operation handset, and they are connected with a 4-core bus cable.

Further, the wireless operation transmitter has panel buttons, an antenna, a working indicator light and a magnetic switch.

Further, there are panel buttons, power indicator light, work indicator light and output interface on the wired operation handheld.

Further, both the wireless operation transmitter and the wired operation hand-held device have 8 buttons, which are total stop, pull stop, left, right, breaking up and breaking down, which respectively correspond to power failure of the main machine of the coal shearer, traction stop, Walking to the left, walking to the right, the coal cutting section rises, the coal cutting section descends, the crushing rises, and the crushing falls.

The buttons on the wireless operation transmitter and the wired operation handheld can send remote control operation commands to the coal shearer, wherein the operation commands of the wireless operation transmitter are transmitted to the wireless receiving module of the remote control signal receiving device in the form of radio wave signals, The wireless receiving module demodulates, checks and decodes the received operation command signal to generate the execution action command of the coal shearer, which is sent to the main controller of the coal shearer through the output interface to complete the corresponding action, thereby realizing The remote control operation of the coal mining machine; the key operation command of the wired operation handheld is transmitted from the wired receiving interface to the remote control signal receiving device through the bus cable, and the remote control signal receiving device checks and decodes the received operation command signal to generate The execution command of the shearer is sent to the main controller of the shearer through the output interface to complete the corresponding action, thereby realizing the remote control operation of the shearer.

The system has two modes of wireless remote control operation and wired remote control operation. This system firstly effectively solves the shortcoming of the single remote control operation mode of the current coal mining machine. When the reliability and effectiveness of the wireless remote control are reduced due to the deterioration of the radio wave transmission environment, the remote control operation can be carried out in a wired manner; secondly, the remote control signal reception The device isolates the wireless operation transmitter and the wired operation hand-held device from the main controller of the coal mining machine, effectively reducing the interference of the noise brought by the remote control system on the main control unit of the coal mining machine; The remote control system of the coal mining machine is upgraded and transformed.
