Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment is clearer, below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
The utility model comprises that CANopen protocol conversion module 1, CAN transceiver 2, indicator light 3, DIP switch 4 form; Described CANopen protocol conversion module 1 is connected with CAN-bus bus 6 by CAN transceiver 2; User CPU5 can link to each other with CANopen protocol conversion module 1 by the UART interface, realizes the exchanges data with CANopen equipment; Indicator light 3 directly links to each other to show CANopen protocol conversion module operating state and baud rate and node address setting with CANopen protocol conversion module 1 with DIP switch 4.The CANopen protocol conversion module adopts a embedded type C ANopen protocol conversion module XGate-COP10, this module integration CANopen slave station protocol stack, follow CiA DS301 V4.02 and design.Described CAN transceiver adopts CTM8251T isolation transceiver, this transceiver is inner integrated all essential CAN isolation and CAN sending and receiving devices, and have the effect of CAN-bus bus overvoltage protection.
Operation principle of the present utility model is as follows:
The CANopen protocol conversion module adopts CANopen protocol conversion module XGate-COP10, this module integration CANopen slave station protocol stack, one road CAN interface is provided, can be connected with the CANopen network by this interface, traffic rate is 5Kbps-1Mbps.XGate-COP10 provides two-way UART interface in addition, a-road-through letter interface (communication baud rate is 1200-115200bps), external user CPU can send to the CAN-BUS bus with data in the mode of PDO message by this interface, and read RPDO data from the CAN-BUS bus, also can be used for the configuration module relevant parameter; Another road debugging interface (communication baud rate for fixedly 115200bps) is used for the debugging of production debugging stage and exports and the program upgrade interface.
XGate-COP10 inside has the input-buffer of 96 bytes and the output buffer memory of 96 bytes, can support to reach 12 RPDO and the transmission of TPDO process data, is applicable to the occasion that various interference are strong, requirement of real time is high.
The CAN transceiver adopts CTM8251T isolation transceiver, physical interface between CANopen network and the protocol conversion module is provided, mainly contain two parts function: the transmitting-receiving of CANopen bus and photoelectricity isolation, after the photoelectricity isolation, convert the differential networks signal on the CANopen network to digital signal and send into protocol conversion module, perhaps the digital signal on the protocol conversion module is converted to the differential networks signal and after the photoelectricity isolation, give the CANopen network.
The indicator light design defines according to CANopen protocol specification document D S303-3, be used for display module work at present state, the utility model is indicated when the front module status with two LED light, a running LED, be used to refer to the current running status of module, as: pre-operation state, operating state etc.; Another error condition indicator light is used to refer to when the front module type that makes a mistake, as: Sync mistake, bus-off etc.
DIP switch is used for node ID and node baud rate are set, if the toggle switch value is effective, enables this value when then powering on, and can not use even store legal ID value in memory.If at run duration, main website has carried out the LSS setting to protocol conversion module, then uses the value after arranging, but after the CANopen communication board re-powers or restarts, still uses the value of toggle switch.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
