Embodiment 1

[0013] What the present invention aims 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 for real-time applications, which can use twisted pair wires to transmit signals. The CAN protocol was developed by Robert Bosch Company in Germany. It was originally used for communication between various electronic components in automobiles, so as to replace expensive and cumbersome distribution harnesses. The robustness of this protocol extends its use to other automation and industrial applications. CAN bus belongs to one of the field buses and is a multi-master serial communication bus with high bit rate and high anti-electromagnetic interference performance, which can detect any errors generated. It is a communication protocol with excellent performance and widely used used in various industries.

Embodiment 2

[0020] This embodiment is the optimal use scheme of four CAN communication circuits in Embodiment 1, wherein two point-to-point CANBIDI communication circuits connected with the left and right bracket controllers, one point-to-point CAN communication circuit connected with the man-machine interface box, and one connected with the remote monitoring A point-to-face CANBUS communication circuit with a broadcast function connected to the host bus.

[0021] Two identical single-line CAN bus communication circuits are used between the bracket controllers to realize data communication between the controllers, and two identical single-line CAN bus communication circuits are used between the bracket controller and the human-machine interface to communicate between the human-machine interface and the man-machine interface. Data exchange is performed between the bracket controllers, the man-machine interface sends various operation instructions to the controller, and the controller sends ...

Embodiment 3

[0024] This embodiment is a preferred solution of Embodiment 1 or 2. The connecting cable and its plug and socket of the CAN communication circuit are 4-core communication cables and their plug and socket. One of the 4-core communication cables connected to the left and right bracket controllers and its plug socket is CANBIDI cable 1, the other is CANBUS cable 2, the other is 12V power cable 3, and the other is ground cable 4. The schematic diagram of the socket Such as image 3 shown. The 4-core communication cable and its plug and socket connected to the point-to-point CAN communication circuit connected to the man-machine interface include: one single-wire CAN cable 5, one 12V power supply cable 6, one ground cable 7, and one power control Cable 8, the schematic diagram of the socket is as follows Figure 4 shown.

[0025]Ordinary CAN bus adopts differential mode, using two lines to realize CAN bus data communication. To use mine standard 4-core cable to realize two sep...

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-line CAN bus, which is an electronic device, a hydraulic support control device for fully mechanized coal mine mining face, and a CAN (Controller Area Network, Controller Area Network) ) An electronic device for contacting and communicating between the hydraulic supports supported by the bus and between the master controls. Background technique [0002] The hydraulic support is an important equipment used on the fully mechanized mining face of the coal mine. 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 hydraulic cylinders and hydraulic control systems. In actual work, there is basically no single hydraulic support that works independently. Many hydraulic supports work together to support the working surface. , the early hydraulic supports were all independent, and the simp...
