The invention discloses a regional
water environment heavy
metal monitoring system and an operating method. The regional
water environment heavy
metal monitoring system comprises a monitoring
management system and a plurality of monitoring terminals, wherein the monitoring terminals are connected with the monitoring
management system through
general packet radio service (GPRS); a
central processing unit of the monitoring
management system is connected with a data transmitting and receiving module, a
data analysis processing module, a
database management module and a display or a user terminal; the data transmitting and receiving module is connected with a
database storing
global positioning system (GPS) information, information
geographic information system (GIS) and correlated heavy
metal concentration information detected by all the monitoring terminals; a master control module of each monitoring terminal comprises an embedded processor, a
clock and a GPRS sub-module; a detection module comprises a temperature sensor and a heavy metal electrochemical
sensor array. According to the operating method, the temperature and the heavy metal concentration, monitored by the monitoring terminals, of a
water environment are transmitted to the monitoring management
system to be stored and displayed, and are compared with standard values and historical data through the
data analysis processing module; when the polluted
water quality is determined or the concentration of certain heavy metal is suddenly increased to a higher level, an alarm is given. According to the regional water environment heavy metal
monitoring system and the operating method, the
pollution of a
water body is timely found by real-time sampling analysis and
dynamic monitoring; the monitoring terminals are simple to network and easy to expand.
