Embodiment Construction

[0022] The present invention takes the K-band vehicle-mounted receiver as the application background, and provides a communication technology for controlling multi-channels by changing single-channel serial SPI data input into multiple-channel SPI data output based on CPLD. SPI port communication can build a small high-speed synchronous communication network for control. This network has a simple structure and low cost, and can be widely used for data transmission between controllers or controllers and peripheral chips. The invention provides a specific implementation method of multi-SPI port communication based on CPLD on the basis of careful analysis of SPI port communication time sequence, and carries out debugging and verification, and the effect is good.

[0023] Below in conjunction with accompanying drawing, content of the invention will be further described:

[0024] refer to figure 1 Shown, the communication device of a kind of K band vehicle-mounted receiver compri...

Abstract

The invention discloses a communication device and communication method of a K wave band vehicle-mounted receiver. The communication method comprises the steps of adopting a CPLD as a slave unit to achieve communication with an SPI of a host computer and carrying out SPI communication between the CPLD as a primary device and the K wave band receiver. The signals of the SPI of the host computer comprise clock signals, data input signals, chip selection signals, shifting register signals and data latching signals. The chip selection signals serve as a data sending state, the clock signals serve as data impulsing, and the data latching signals serve as a sending completion state. When the CPLD serves as the host computer, after being split, analyzed and recombined according to the communication protocol, received data are sent to the K wave band receiver, so that data transmission is achieved. By the combination of the structure with the communication method thereof, the shortcoming that a systematic and high-reliability communication device of the K wave band vehicle-mounted receiver does not exist in the prior art is overcome.

Description

technical field [0001] The invention belongs to the technical field of communication of vehicle-mounted microwave active products, and in particular relates to a communication device and a communication method of a K-band vehicle-mounted receiver, and mainly relates to a multi-data pulse transmission system and a method thereof. Background technique [0002] At present, in the receiver, various communication methods are used to complete the data transmission between the upper layer and the lower controller and the control chip, and realize the corresponding control functions; the design and implementation of various communication functions have become an important part of the receiver design Part, but there is no communication device for a systematic and reliable K-band vehicle receiver. Contents of the invention [0003] The object of the present invention provides a kind of communication device and the communication method of K band vehicle-mounted receiver, comprise ad...
