摘 要 ：基于Web Service 技术,结合个人数字助理(personal digital assistant,PDA)的使用,开发了城市绿地有害生物实时监控系统,从而解决城市绿地有害生物预警监测中信息交流不畅和共享困难的问题。调查人员手持PDA进行实地信息采集,通过无线网络即时传输;系统管理平台实时接收调查结果,经分析处理后进行信息发布。该系统应用于上海世博园区绿化植物有害生物实时监控,共收集有害生物信息153次,发布预警信息16期。结果表明,基于Web Service的城市绿地有害生物PDA实时监控系统能即时获取并发布信息,实现对有害生物的实时化、信息化监控。
Abstract:The authors of the paper developed a pest real-time monitoring system of urban green space based on Web Service, combined with the use of PDA (personal digital assistant), to solve the problem of information exchanging and sharing occurring in urban green space pest early warning and monitoring. Investigator can gather pest information by PDA, which transmits data via wireless; meanwhile the system management platform can receive the survey results, and release pest reports after analysis and processing. The system, applied to monitoring open green space of Shanghai EXPO Site, received 153 pieces of information and announced 16 alarming reports. The results showed that the PDA pest monitoring system based on Web Service can gather and announce pest information forthwith, and realize the pest real-time and informative monitoring.
