The invention discloses an unmanned-device-based water quality patrolling, contaminant originating system and a method thereof, wherein the system comprises an unmanned plane, an unmanned ship and a shore-based monitoring system. The unmanned ship carrying a water quality detection device is capable of performing on-line detection of water quality across a water area at which the unmanned ship is located. The unmanned ship carries a small-sized unmanned plane, and a ship body thereof provides docking and charging device for the unmanned plane, thereby achieving a wide patrolling range of the unmanned plane. Both the unmanned ship and the unmanned plane are equipped with an HD (High-Definition) video monitoring system for separately achieving a water surface patrolling function. The invention provides a brand new water quality monitoring approaches by means of carrying theunmanned plane on the unmanned ship for patrolling a polluted water area in a space formula manner. A combination of the unmanned plane and the unmanned ship uses a characteristic of a wide view of the unmanned plane, to further achieve tracking of a pollution source, and also better compensates for defects of separate patrol of the unmanned ship or unmanned plane, thereby facilitating high efficiency and precision of water quality monitoring, and improving informationalized level of water quality monitoring.

The environmental monitoring control center is used for receiving, storing and then processing the real-time water quality monitoring data, and carrying out active remote control on the field water quality monitoring devices.

Apparatus, systems and methods for detecting and transmitting sensory data over a computer network

A vapor sensing device that is sufficiently small and lightweight to be handheld, and also modular so as to allow the device to be conveniently adapted for use in sensing the presence and concentration of a wide variety of specified vapors. The device provides these benefits using a sensor module that incorporates a sample chamber and a plurality of sensors located on a chip releasably carried within or adjacent to the sample chamber. Optionally, the sensor module can be configured to be releasably plugged into a receptacle formed in the device. Vapors are directed to pass through the sample chamber, whereupon the sensors provide a distinct combination of electrical signals in response to each. The sensors of the sensor module can take the form of chemically sensitive resistors having resistances that vary according to the identity and concentration of an adjacent vapor. These chemically sensitive resistors can each be connected in series with a reference resistor, between a reference voltage and ground, such that an analog signal is established for each chemically sensitive resistor. The resulting analog signals are supplied to an analog-to-digital converter, to produce corresponding digital signals. These digital signals are appropriately analyzed for vapor identification. The device can then subsequently transmit the digital signals over a computer network, such as the Internet, for analysis at a remote location.

The invention mainly discloses a river way multipoint water quality monitoring apparatus and a monitoring method therefor. The monitoring apparatus includes a monitoring body, a power apparatus and water collectors. A solar cell panel, a storage battery and a protective cover are disposed on the top surface of the monitoring body. At least three water collectors are disposed under the monitoring body through telescopic rods. A water storage chamber is arranged in each water collector. A water collection port is arranged on the bottom of each water collector and is provided with a sealed cover. A sampling tube is disposed in each telescopic rod. A detection chamber provided with a detection head and a wireless communication module are arranged in the monitoring body. One end of the sampling tube is connected to the water storage chamber. The other end of the sampling tube is connected to a splitting pipe through an electromagnetic valve. The splitting pipes are connected to the detection chamber.

If the difference between a present calculated value and a normal action value is in the range of a default threshold, the fact represents that the fish behaviors are normal and judges that water quality conditions are good. If the difference is beyond the range of the default threshold, the fact judges that the water is polluted. The biologic water quality monitoring system reduces cost, is suitable for large-scale application and has good practicality.
