【摘要】：目前工程机械租赁行业正处于一个蓬勃发展时期,在这种激烈的市场竞争环境下,不断暴露出租赁企业在工程机械管理与计费方面的问题。由于工程机械种类繁多、结构复杂,很容易出现故障,因此对工程机械进行远程实时监控至关重要。同时大多数工程机械单台价格偏高,越来越多的工程机械制造公司向客户提供租赁服务。具备计费功能的远程监控平台已成为工程机械制造公司、施工企业以及银行的迫切需要。本文给出了一种高性价比的工程机械远程监控与计费系统的设计方案。远程监控平台以MSP430F149为核心,外扩了光电开关模块、薄膜键盘模块、RS485总线、GPRS模块、RFID模块、GPS模块、大容量数据存储模块等多个电路单元。监控平台通过RS485总线接口可以与特定组合的数据采集模块进行高速通信,最终能够满足具体型号工程机械远程监控的目的。在硬件平台的基础上,在EW430的编程环境下进行监控平台功能模块的软件设计。为方便租赁企业对工程机械工况数据以及计费信息的有效管理,论文中叙述了远程管理中心软件以及系统数据库的设计开发过程。通过分析所传输数据的类型,论文设计了一种稳定的监控平台与远程管理中心之间的远程通信协议。系统测试章节中对系统的监控功能、计费功能以及软件各模块的功能进行测试,并提出一定的改进方案。
[Abstract]:At present, the leasing industry of construction machinery is in a period of vigorous development. In this fierce market competition environment, the problems in the management and accounting of construction machinery are constantly exposed. Because of the variety of construction machinery, the structure is complex. It is very easy to break down, so it is very important to monitor the construction machinery in real time. At the same time, the price of most construction machinery is on the high side. More and more construction machinery manufacturing companies provide leasing services to customers. The remote monitoring platform with billing function has become a construction machinery manufacturing company. This paper presents a design scheme of a high performance-price ratio remote monitoring and charging system for construction machinery. The remote monitoring platform takes MSP430F149 as the core and extends the optoelectronic switch module. The membrane keyboard module includes RS485 bus / GPRS module, RFID module, large capacity data storage module and so on. The monitoring platform can communicate with the data acquisition module with special combination through RS485 bus interface. Finally, it can satisfy the purpose of remote monitoring and control of concrete construction machinery. On the basis of hardware platform, The software design of the function module of the monitoring platform is carried out under the programming environment of EW430. In order to facilitate the effective management of the working condition data and billing information of the construction machinery in the leasing enterprise, This paper describes the design and development process of remote management center software and system database. In this paper, a stable remote communication protocol between the monitoring platform and the remote management center is designed. In the chapter of system testing, the monitoring function, billing function and the function of software modules are tested, and some improvement schemes are put forward.
