Problems solved by technology

[0003] In other applications of the same type, special codec chips are directly used to code and decode data, but the control of these chips and the setting of internal registers are relatively cumbersome, and the peripheral circuit connections of these chips are relatively complicated.
Therefore, although a special chip can be used to implement codec, it is not very convenient to use in practice.

Embodiment Construction

[0031] See Figure 1. The communication terminal module with encoding and decoding capabilities of the present invention uses a C8051F133 single-chip microcomputer and its peripheral circuits. The communication terminal module is embedded in the single-chip microcomputer system and includes an edge trigger capture module 1, a first timer 2, and a second timer. 3, the third timer 4, data decoding module 5, data encoding module 6, memory 7, single-chip microcomputer 8, and I / O output module 9; Described edge trigger capture module receives data to be decoded, and sends to the third timing in sequence device and the second timer, after timing, it is sent to the data decoding module for decoding, and the decoded data is sent to the memory for storage. The memory is called out to the data encoding module, and is timed by the first timer, and the encoded data is output through the I / O output module. Using the timer, I / O output module and edge capture module of the single-chip microc...

Abstract

A communication module with coding / decoding ability is prepared as using edge trigger module to receive decoding data and sending it in sequence to the third and the second timer then sending to data decoding module for decoding as per timing, storing decoded data in storage, receiving data from storage by monolithic computer, calling data requiring to be coded to data coding module for coding through storage and outputting coded data by I / O module as per timing of the first timer.

Description

technical field [0001] The invention relates to a communication terminal module capable of encoding and decoding in an electronic non-stop toll collection system (hereinafter referred to as ETC toll collection system) and a data sending and receiving method thereof. Background technique [0002] In the ETC charging system, the communication terminal module with codec capability is an important part, and its working performance directly affects the working performance of the ETC charging system. [0003] In other applications of the same type, special codec chips are directly used to code and decode data, but the control of these chips and the setting of internal registers are relatively cumbersome, and the peripheral circuit connections of these chips are relatively complicated. Therefore, although a special chip can be used to implement codec, it is not very convenient to use in practice. Contents of the invention [0004] The purpose of the present invention is to provi...
