Embodiment 1

[0013] What the present invention is to solve is to use a standard communication protocol to solve the communication problem between the existing hydraulic supports, and the present invention selects the CAN bus. CAN bus is a serial communication protocol bus used for real-time applications. It can use twisted-pair wires to transmit signals. The CAN protocol was developed by Robert Bosch in Germany. It was originally used for communication between various electronic components in automobiles to replace expensive and bulky power distribution wiring harnesses. The robustness of this protocol is that its use extends to other automation and industrial applications. CAN bus is one of the field buses. It is a multi-master serial communication bus. It has a high bit rate and high anti-electromagnetic interference performance. It can detect any errors generated. It is a communication protocol with excellent performance. Used in various industrial sectors.

Embodiment 2

[0020] This embodiment is the preferred use scheme of the four CAN communication circuits in the first embodiment, of which two point-to-point CANBIDI communication circuits connected to the left and right support controllers, one point-to-point CAN communication circuit connected to the man-machine interface box, and one with remote monitoring Point-to-face CANBUS communication circuit with broadcast function connected to the host bus.

[0021] Two identical single-wire CAN bus communication circuits are used between the support controllers to realize data communication between the controllers, and two identical single-wire CAN bus communication circuits are used between the support controller and the man-machine interface for the man-machine interface and the man-machine interface. The support controllers exchange data, the man-machine interface sends various operation instructions to the controller, and the controller sends various display control commands to the man-machine in...

Embodiment 3

[0024] This embodiment is a preferred solution of the first or second embodiment, and the connecting cable of the CAN communication circuit and its plug socket are 4-core communication cables and their plug sockets. One of the 4-core communication cables connected to the left and right support controllers and their plug sockets is CANBIDI cable 1, one is CANBUS cable 2, one is 12V power cable 3, and the other is ground cable 4. The schematic diagram of the socket As shown in Figure 3. The 4-core communication cable and its plug socket connected to the point-to-point CAN communication circuit connected to the human-machine interface include: a single-wire CAN cable 5, a 12V power cable 6, a ground cable 7, and a power control The schematic diagram of cable 8, socket is shown in Figure 4.

[0025]Ordinary CAN bus adopts a differential mode, and uses two wires to realize CAN bus data communication. To use the mine standard 4-core cable to realize two separate CAN bus communication, i...

Abstract

The invention discloses a support controller constructed by single-thread CAN total thread, which is characterized by the following: comprising a slice machine module; connecting the slice machine module to a RS232 transceiver; connecting the RS232 transceiver to a RS232 interface; connecting the slice machine to a AD transform module; connecting the AD transform module to 3 path analog quantity inputting mouth; connecting the module of the slice machine to magnetic valve driving module; connecting the magnetic valve driving module to 16 path magnetic valve outputting interface; constituting CAN communicating circuit with single-thread CAN transceiver and CAN controller; connecting the slice module to the CAN communicating circuit; adopting earth cord as return circuit for the single thread CAN transceiver. This invention uses single strip circuit to realize communicating return circuit of the support controller.

Description

Technical field [0001] The invention relates to a support controller composed of a single-wire CAN bus, which is an electronic device, a hydraulic support control device used in a fully mechanized coal mining face in a coal mine, and a CAN (Controller Area Network, Controller Area Network) ) The electronic device for communication and communication between the hydraulic supports and the master control supported by the bus. Background technique [0002] Hydraulic supports are important equipment used on fully mechanized coal mining faces in coal mines. There are dozens of hydraulic supports working at the same time on each coal mining face. Each hydraulic support has an independent hydraulic system, including a hydraulic cylinder and a hydraulic control system. In actual work, there is basically no single hydraulic support working independently. Many hydraulic supports work together to support the working surface. , The early hydraulic supports were all independent. Simple mechani...
