  ■ 船闸计算机监控系统
华辰电控自2003年进入交通航运系统自控领域,通过10余座大中型船闸的现场应用,成功地总结出各种通航设施(平板门,升卧门,人字门等)的安全可靠的控制方案。
HC2000C船闸计算机监控系统是华辰电控专为交通水运工程提供的自动化系统解决方案,系统采用基于PLC的集散型分布式控制结构进行总体设计,控制功能分布在网络的各个节点中,任一节点的故障不影响其它节点的正常工作。各单元既可以对所辖对象单独进行控制操作,又可以通过现场总线和通信网络,协同进行联合控制,完成正常运行模式下(或通闸模式)上行、下行过闸的自动集中控制。
2007年,华辰电控成功开发了(目前已投运)一套网络联合调度收费系统,采用客户机/服务器模式,通过Microsoft SQL Server、Oracle、MySQL、PostgreSQL等网络数据库平台的访问与服务,实现同一航道多座船闸的联合调度收费,系统配套使用IC无线射频卡来存储船舶的基本信息及当前调度收费信息,实现IC无线射频卡数据存储区与船闸本地数据库间数据的同步。在各船闸间还没有实现网络连接的情况下,系统也能快捷、有效地完成联合调度收费任务。系统软件采用JAVA编制,除了Windows平台,系统在 Linux、Unix平台上也能稳定运行,为系统在船闸现场安全、有效、快速、稳定运行提供必要保障。

Since entering the navigation automation control field in 2003, HCECE has successfully worked out safe and reliable control solutions for various navigation facilities (plain gate, miter gate and tumble gate, etc.) through the smooth operation of over 10 large- and medium-sized ship locks.
The SCADA system of HC2000C series for the ship locks is the HCECE solution specifically for the waterway navigation projects. The system of overall PLC-based control structure is designed in distributed configuration. With the control functions distributed at each nodes of a network, the fault at any node will not affect the normal operation of the others. The objective units can either be controlled separately from the others or exert ganged operation through the site busbar and communication network for concentrated automatic control over the normal ship navigation through the ship locks.
In 2007, HCECE successfully developed the network-based joint regulation and toll collection system, adopting the client/server mode. By the online visit/service platform of Microsoft SQL Server, Oracle, MySQL and PostgreSQL, the joint regulation and toll collection is realized at several ship locks on one navigation channel. The system adopts the wireless RF IC cards to store the basic and current toll collection information of ships, making the IC card-stored data synchronized with the ship lock-stored data. In case the ship locks are not yet interconnected through network, the system can also quickly and effectively realize the joint regulation and toll collection system. The system software is JAVA programmed, it can steadily operated on Window platform as well as on Linux and Unix platform, which offers a necessary guarantee for safe, effective, quick and steady operation of the ship locks.

Main Functions
Real-time data Sampling
Operational display, control and operation
Ganged control over the signal lamps for entering and exit of the lock
Safety monitoring and event alarm
Data communication
Data statistics
Hardware self-diagnosis
Industrial TV monitoring
