Embodiment Construction

[0021] 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.

[0022] Below in conjunction with accompanying drawing, content of the invention will be further described:

[0023] refer to figure 1 Shown, the communication device of a kind of K band vehicle-mounted receiver compris...

Abstract

A communication device and communication method for a K-band vehicle-mounted receiver, including using a CPLD as a slave device to realize SPI communication with a host, and using the CPLD as a master device to perform SPI communication with a K-band receiver. The host SPI port includes clock signal, data input, chip select, shift register, and data latch. The chip select signal is used as the data transmission state, the clock signal is used as the data transmission pulse, and the data latch signal is used as the transmission end state. When the CPLD is used as the host, the received data is split, analyzed, and reassembled according to the communication protocol, and then sent to the K-band receiver to realize data transmission. Such a structure combined with its communication method avoids the defect that there is no systematized and reliable K-band vehicle-mounted receiver communication device in the prior art.

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 ado...
