Wecon (China) has developed several human machine interfaces (HMI) providing for example interfaces for camera, laser printer, serial port and Ethernet. The TFT displays also support optionally CANopen.
THE HMI PRODUCTS ARE USED in off-highway vehicles, packaging and textile machines as well as batching machines. They are equipped with TFT displays ranging from 4,3 inch to 10,2 inch. The 400-MHz processor and the 128-MiB flash-memory provide the hardware base to control the peripherals including the optional CANopen interface. J1939 software support is also available on request. The device can be equipped with additional USB sticks or SD cards. The Chinese company supplies Apple-style screen pictures, fonts, etc. One of the applications is a Chinese hybrid-engine bus with combustion engine and electrical motor. The HMI shows the status of the powertrain to the driver. Wecon’s CANopen displays are also used in Lovol’s construction machines.
