Automatic Observation System for Debris Flow

东川泥石流自动化观测系统是在原有的半自动化监测系统基础上研制完成的。它通过综控中心、地声遥测、泥位遥测、雨量遥测、有线泥位和冲击力接口六个子系统共同完成对泥石流构成的一些主要参数包括降雨量、地声强度、泥位高度、表面平均流速、冲击力强度等数据进行同步采样并储存 ;系统对现代软硬件技术的广泛运用使该系统具有很高的智能性和可扩充性。

Automatic Observation System for Debris Flow (AOSFDF for short), as a derived device from the original semi_automatic monitoring system, includes the flowing six components: ①control center, ②ground sound telemetering, ③mud_depth telemetering, ④precipitation telemetering, ⑤wired_mud_depth interface and ⑥impulsive_force interface, each of which is made up with both softwares and hardwares. The control center conduct the communication both wire_less data and voice with exterior subsystems, receives data from radio or wired monitors, exchange the commands and datas between the center box and PC, and set various warning parameters with computers or center box directly. Meanwhile the PC's software do some high level control, some data analysis, data processing, and so on. Furthermore, the control center is capable of visiting the work states at any time and modify all the parameters for every subsystem. The sorftwares of control center on PC (programed with Visual C++) provide real_time control process and data analysis which work on Windows 98/NT platform. it provide a universal standard form for dada file received for being reused easily. All of the field devices of subsystems (including precipitation telemertering, ground sound metering, mud_depth metering, etc.) consist of the corresponding hard components, such as sensor, center processor unit, transceiver, serial process, and so on. After intelligent analysis and process, the field devices send the processed data to the control center, give the right to proceed and save data to the center for next work. The following points characterize the system:(a) All of subsystems serve the intelligent power_supply manage property, this makes it possible for the whole system to work normally in special cases (i.e. A.C. Power failure). (b) Provide the interface for old devices to transform or communicate with digits, made the system through uniform communication protocol, capable of concert working and ensuring the integrity and unity for various data. (c) The control center, besides supporting all of subsystems, offers uniform commands and data interfaces. (d) The parameters of subsystems can be modified either on the spot or through remote control by the control center. (e) The PC provides both the advanced control manage software based on Chines Window software and the standard, uniform dbase files, this makes further work considerably convenient. (f) The instrument board operation function, offered by control center at comprehensive control center provides Chinese LCD menu, is capable of working normally to install warning parameters, setup datetime and read data even in case of the computer's shutdown.
