Embodiment Construction

[0023] Such as figure 1 , the whole system consists of on-board consumer terminal 1 including digital transmission OBU (on board unit), yard controller (Monitor) 2, yard data processing center 3, and bus company settlement management center 4. Each vehicle-mounted consumer terminal is connected to a data transmission OBU. figure 2 As shown, the data transmission unit includes a central processing unit MCU, a data storage unit connected to the MCU, and a zigbee radio frequency unit connected to the MCU. The digital transmission OBU is connected to the on-board consumer terminal through RS232 or 485, receives the transaction data transmitted by the on-board consumer terminal, and issues blacklist and other instruction information. There is a storage unit on the digital transmission OBU, which is used as a temporary storage for the transaction data to be uploaded and the data sent by the yard controller. The digital transmission OBU completes the network construction through t...

Abstract

The invention discloses a bus-mounted consumption terminal data transmission system based on zigbee. A bus-mounted consumption terminal is connected with a bus lot monitor in zigbee wireless mode through a data transmission unit on board unit (OBU). The bus lot monitor builds a wireless network through a coordinator function module of the zigbee and is connected with a microcomputer device of a bus lot data processing center in universal serial bus (USB) or recommended standard (RS) 485 interface mode. The bus lot data processing center is connected with a microcomputer device of a bus company settlement management center through internet. In addition, the data transmission unit comprises a central processing unit micro controller unit (MCU), a data storing unit connected with an MCU and a zigbee radio frequency unit connected with the MCU. The bus-mounted consumption terminal data transmission system based on the zigbee replaces a traditional manual collecting method, saves labor cost, reduces possibility of manual errors, well solves the problems that efficiency is low and error is easy to make in a manual collecting process, and simultaneously well solves the problems of high device cost and later-period operation cost of a general packet radio service (GPRS) method.

Description

technical field [0001] This patent belongs to the field of intelligent public transportation, and is specifically applied to the uploading and downloading of information such as transaction data and blacklists of vehicle-mounted consumer terminals in the public transportation IC card toll management system. Background technique [0002] Traditional data upload and download mainly have the following two modes: [0003] 1. Manual collection [0004] Use the hand-held data acquisition machine and the acquisition card to perform the following operations on the bus consumption terminal - collect or re-collect consumption data, download blacklist records, and automatically check the vehicle clock [0005] 2. GPRS real-time transmission [0006] "GPRS"--General Packet Radio Service [0007] Through the wireless (GSM, CDMA) Internet network provided by the GPRS operator, the transaction data on the vehicle is transmitted to the management center in real time, and the management c...
