Below in conjunction with the drawings and specific embodiments the utility model is described further.
There is certain proportional relation in the SS value (solid suspension concentration) of finding sewage in practice with the COD value.Therefore SS instrument (solid suspension concentration tester) can be installed, the online sewage SS value of enterprise's discharging that detects is with the real-time sewage quality situation of grasping enterprise's discharging.And develop a water quality and trigger sampling controller automatically, the SS signal that the SS instrument detects is handled, when the SS value surpasses setting value, trigger the automatic sampling instrument of water quality and sample automatically, arrange high-concentration sewage steathily to prevent enterprise's intermittence.This water quality triggers sampling system automatically, comprise that water quality triggers sampling controller and solid suspension concentration tester automatically, as shown in Figure 1, described water quality triggers sampling controller automatically and comprises data acquisition transmission instrument (SMA-DTU), galvanic separation 6 and 24V power module 1, the port 4 of wherein said data acquisition transmission instrument is used for the delivery flow rate signal, port 6 is used for transmission SS signal, described data acquisition transmission instrument connects the solid suspension concentration tester by galvanic separation 6, connects by terminal row 2 between described solid suspension concentration tester and the described galvanic separation 6.Described 24V power module 1 is data acquisition transmission instrument and galvanic separation 6 power supplies.This water quality triggers sampling controller automatically can also comprise air switch 3, described air switch 3 control terminals row 2, thus control described solid suspension concentration tester.
The SMA-DTU module:
SMA-DTU possesses the 4-20mA data acquisition, output, real-time online teletransmission reception data are handled, controlled to data, and functional module is seen Fig. 2, mainly realizes following function:
Data Control is handled
The Data Control processing module is core with the ARM-Cortex-M3 processor, have simple in structure, function is strong, low in energy consumption, programming characteristics simple to operation.Mainly monitor supervision platform instruction and on-the-spot website flow, SS value, instrumented data, control output are handled.The processing, warning limit value, warning limit value dead band, the instantaneous value that comprise the parameter alarm are reported to the police or semi-invariant warning, relay actuation time etc.And trigger water quality automatic sampler instrument according to the condition that monitor supervision platform arranges and work.
Wireless data communication module (DTU)
DTU (Data Transfer Unit) data transmission unit is serial data to be converted to the IP data or the IP data to be converted to the wireless terminal device of serial data by cordless communication network.Select GPRS network in the system for use, China Mobile's GPRS coverage rate is extensive and data transmission stable, inserts the mobile SM card of not arrearage and can realize the data double-way communication in the wireless data communication module.Data transmission after the data communication module is handled the Data Control processing module is to monitor supervision platform.The parameter that data communication module need arrange mainly contains and is sent to IP address, destination, port numbers, site number, data transmission bauds etc.
Galvanic separation
Adopt the LU-G1111AF1 type isolator of ANTHONE in the controller, main effect is to reduce outer signals to the interference of the 4-20ma simulating signal of input.
The controller principle of work
Controller is respectively from flowmeter, SS instrument access flow signal, SS signal, and handled by the flow signal of SMA-DTU and SS signal.The mode that triggers sampling instrument work has semi-invariant, two kinds of modes of SS value, and concrete principle of work is as follows:
1, when the SS value does not reach setting value, when semi-invariant reaches setting value, trigger the automatic sampling instrument sampling of water quality after the VO1 closure, trigger the back flow accumulation amount return-to-zero New count of laying equal stress on;
2, when the SS value surpasses setting value, trigger the automatic sampling instrument sampling of water quality after the VO3 closure, trigger the automatic sampling instrument of back water quality and trigger sampling by setting cycle, namely surpass setting value in the time period in the SS value, VO3 triggers the water quality sampling instrument by the regular closed back of setting-up time and samples automatically.
The mode that terminal triggers, parameter are by the long-range setting of controller monitoring platform.
The controller monitoring management platform
