Existing LonWorks communication systems most multipotency receives the data of two-way LonWorks buses simultaneously, to growing Train big data quantity information exchange efficiency bring certain restriction.Therefore design it is a can realize parsing forwarding train between LonWorks bus datas and meet the communication module of big data quantity information exchange and comply with speed Train Development demand.

The content of the invention

In order to solve the above problems, the utility model provides a kind of multichannel LonWorks communication systems, the communication system Multichannel LonWorks bus datas can be received simultaneously, are improved and are subtracted under the efficiency of data interaction, identical data volume disposition The quantity of LonWorks communication modules is lacked, has saved and take train space.

In order to achieve the above object, the technical solution adopted in the utility model is：

A kind of multichannel LonWorks communication systems, including the single-chip microcomputer being embedded in multichannel LonWorks communication systems, it is single Piece machine has the receiving terminal and transmitting terminal of signal, wherein, the receiving terminal of single-chip microcomputer is parallel with multiple Lon transceivers, single-chip microcomputer Transmitting terminal is connected with CAN and sends chip.

As further optimization of the present utility model, single-chip microcomputer includes being embedded in the processor inside single-chip microcomputer, the processor For arm processor.

As further optimization of the present utility model, Lon transceivers are 4, and 4 Lon transceivers are connected to list The receiving terminal of piece machine.

As further optimization of the present utility model, the quantity that single-chip microcomputer corresponds to Lon transceivers has multiple RS232 total Line.

As further optimization of the present utility model, CAN is sent connects CAN outside chip.

Compared with prior art, advantage of the present utility model and good effect are：

1st, multichannel LonWorks communication systems of the present utility model, by setting multichannel Lon transceivers, can receive many simultaneously Road LonWorks bus datas, improve at least 1 times of train LonWorks network data exchanges efficiency, reduce under the same conditions The number of communication module, saves space-consuming；

2nd, multichannel LonWorks communication systems of the present utility model, using the high ARM single-chip microcomputers of cost performance, processing speed It hurry up, cost is low；

3rd, multichannel LonWorks communication systems of the present utility model, are designed using technical grade component, meet train various The electrical performance requirements of environment.
