Description

A kind of CAN bus controller that possesses the distant communication function

Technical field

The utility model relates to a kind of bus controller, relates in particular to a kind of CAN bus controller that possesses the distant communication function.

Background technology

Bus is being undertaken exchanges data and command between each subsystem as the passages through which vital energy circulates of Distributed Servo control system, is the important component part of dcs, and its performance quality has directly determined the performance of whole dcs.

In field of automobile control, bus controller generally is divided into again front control module, rear control module, module is controlled on the top that also is provided with that has, the control relation of front control module, rear control module and top control module is equality, difference only is that modules controls respectively different loads, all receive each other on the CAN bus signal and mutually dispatching distribution go to carry out to corresponding control module.

After bus controller is developed, debug it, whether reach the requirement of the development function of being wanted to check its function.In prior art, carry out this type of debugging and can only carry out on the spot, data also can only store processing on the spot, can't satisfy the regulatory requirement of current distant communication.

The utility model content

The utility model provides a kind of CAN bus controller that possesses the distant communication function for the drawback of prior art.

The CAN bus controller that possesses the distant communication function described in the utility model, comprise the bus controller unit that is formed by front control module, rear control module and top control module, also comprise data acquisition module, Data Format Transform module and wireless transmitter module;

Wherein, the input end of described data acquisition module is connected by the CAN bus with the bus controller unit, and receives the data message of bus controller unit output;

The input end of described Data Format Transform module is connected by the CAN bus with the output terminal of data acquisition module, and the output terminal of described Data Format Transform module is connected by USB interface with wireless transmitter module; This Data Format Transform module is converted to the data message of the CAN bus communication standard of data acquisition module output the data message of USB interface communication standard, and carries out the teletransmission emission by wireless transmitter module.

In the CAN bus controller that possesses the distant communication function described in the utility model, by increase, data acquisition module, Data Format Transform module and wireless transmitter module are set, make it possible to the data message of the CAN bus communication standard of bus controller unit is converted to the data message of the USB interface communication standard of computer Direct Recognition, and carry out the teletransmission emission by wireless transmitter module, satisfy current demand to data remote in the bus controller debug process, promoted the convenience of debugging and intelligent.

Description of drawings

Fig. 1 is the structural representation that possesses the CAN bus controller of distant communication function described in the utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to the instructions word to make those skilled in the art.

As shown in Figure 1, the CAN bus controller that possesses the distant communication function described in the utility model, comprise the bus controller unit that is formed by front control module, rear control module and top control module, for realizing the teletransmission purpose of data message, also be provided with data acquisition module, Data Format Transform module and wireless transmitter module.

Wherein, the input end of described data acquisition module is connected by the CAN bus with the bus controller unit, and receives the data message of bus controller unit output.The data message of described bus controller unit output CAN bus communication standard, and pass through the CAN bus transfer to data acquisition module.

The input end of described Data Format Transform module is connected by the CAN bus with the output terminal of data acquisition module, and the output terminal of described Data Format Transform module is connected by USB interface with wireless transmitter module.The requirement of data being read for adapting to computer, described Data Format Transform module are converted to the data message of the CAN bus communication standard of data acquisition module output the data message of USB interface communication standard, and carry out the teletransmission emission by wireless transmitter module.After the equipment such as wireless receiving station that are positioned at far-end receive above-mentioned data message, just can carry out subsequent treatment, analyzing the output situation of CAN bus controller, and provide the debugging suggestion for this CAN bus controller.

Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in instructions and embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
