Embodiment approach
[0039]As a vehicle-mounted device, the multi-protocol bus control device is faced with a relatively complex working environment. In addition to meeting the basic requirements for in-vehicle installation and internal electrical installation requirements for the box structure, the multi-protocol bus control device should also meet the electromagnetic compatibility GJB151A-1997.
[0040] Satisfaction of electromagnetic compatibility requires reasonable electrical design of the equipment itself, as well as reasonable structural design. The processing of the chassis of the multi-protocol bus control device adopts a splicing process to ensure the airtightness of the chassis and prevent electromagnetic leakage; the whole body of the chassis is conductively oxidized before splicing to prevent The metal is oxidized after long-term use, and the conductivity becomes poor. After the conductive oxidation, the electrical airtightness of the equipment structure is greatly enhanced to prevent t...

The invention discloses a multi-protocol bus control device which comprises a main case, a case top cover board, hardware and software. The hardware comprises a network part and a serial port part, an IEM 7010 data exchange module is adopted in the network part, and an IEM618 protocol conversion module is adopted in the serial port part. The software comprises embedded software and upper computer software, the embedded software is solidified to an ARM in an M3 series of a hardware platform, and system protocol parameter configuration is mainly completed by the upper computer software. By the adoption of the multi-protocol bus control device in the technical scheme, the multi-protocol bus control device developed through a method can be widely used for active service equipment such as a scout vehicle and a command vehicle; through comprehensive and reasonable software, hardware and structure design, the compatibility of equipment in each vehicle is greatly improved, and data interaction and information sharing are facilitated; when the equipment is upgraded, even though an interface communication protocol is changed, the normal work of a whole system can not be affected.
Description
technical field [0001] The invention relates to a vehicle-mounted operation system, which enables system key information data to be interactively transmitted in the form of a multi-protocol bus, in particular to a multi-protocol bus control device. Background technique [0002] With the increase in the types and quantities of in-vehicle information equipment, the data exchange between different devices is also more complicated. There are big problems in the system compatibility of serial port devices, CAN port devices, and network port devices, which is not conducive to use during operation. Different devices use different communication protocols according to their own functions. After they are connected to the system, if a fault occurs during operation, the fault point cannot be located quickly, and the operator cannot know whether it is a communication link problem or a fault problem of the device itself. [0003] At present, the data communication interface protocols, com...
