Description
Technical field
The utility model belongs to technical field of sewage, relates to a kind of radio sensing network monitoring system that is used for wastewater treatment especially.
Background technology
Aspect water quality monitoring, traditional water quality monitoring work is main with artificial spot sampling, Laboratory Instruments analysis mainly.Though analysis means is complete in the laboratory, there are low, the defectives such as sampling error big, Monitoring Data dispersion of the monitoring frequency in the laboratory monitoring.Automatic water quality monitoring system is to grow up the seventies in 20th century; As far back as developed countries such as the U.S. in 1970 and Japan surface water such as river, lake are carried out the automatic on-line monitoring, simultaneously the works liquor of city and enterprise has also been carried out the automatic on-line monitoring.The online auto monitoring of water quality has become the effective means of the successional Monitoring Data of timely acquisition, and along with the development of monitoring technology and instrument and meter industry, water quality monitoring work begins to turn to main monitoring direction development to robotization, intellectuality and network simultaneously.
Aspect the production control of municipal sewage plant, mainly be to detect and debugging in early days by the technician is on-the-spot.But owing to need carry out the real-time monitoring of a plurality of project indicators, the pH value of Inlet and outlet water for example, aeration tank dissolved oxygen amount, temperature in the treatment pond or the like.If to the monitoring in real time one by one of these indexs, the man power and material who consumes like this will be huge, and efficient can be not high with real-time yet.Developed country drops into substantial contribution and scientific research strength after two stage treatment is popularized; Change wastewater treatment all by the mode of artificial or simple electrical equipment control; Reinforcement has realized computer control, warning, calculating and instantaneous record to monitoring, operation and the management of sewage treatment facility.To control the introducing sewage disposal process automatically; Raising to the work efficiency of entire process process is significant; By sophisticated equipment and advanced technologies processing procedure, can alleviate operating personnel's work load, and arrange optimum operating mode, energy savings.
The utility model content
For addressing the above problem, the purpose of the utility model is to provide a kind of radio sensing network monitoring system that is used for wastewater treatment, is used to utilize the ZigBee network that each association of sewage is carried out real-time collection and analyzing and processing.
For realizing above-mentioned purpose, the technical scheme of the utility model is:
A kind of radio sensing network monitoring system that is used for wastewater treatment; Comprise at least one road water quality parameter detector; Further comprise ZigBee terminal with the corresponding connection of said every road water quality parameter detector; The ZigBee telegon that is connected with said ZigBee terminal wireless, the host computer that is connected through the RS232 communication interface with said ZigBee telegon.
Compared with prior art, the beneficial effect of the wastewater treatment monitoring network of the utility model employing ZigBee network realization is following:
(1) low-power consumption, under the low power consumption standby mode, No. 5 dry cells of 2 joints can be supported 1 node work 6～24 months, even longer.
(2) low cost through significantly simplifying agreement, has reduced the requirement to communication controler.
(3) low rate, ZigBee be operated in 20～250kbps than low rate.
(4) closely, the transmission range between adjacent node generally between 10～100m, after increasing the RF emissive power, also rises to 1～3km, if pass through the relay of route and inter-node communication, transmission range can be farther.
(5) prolong in short-term, the response speed of ZigBee is very fast, generally changes duty over to from sleep and only needs 15ms, and node connects the entering network only needs 30ms, has further saved electric energy.
(6) that high power capacity, ZigBee can adopt is starlike, sheet and mesh network topology, and by a host node management plurality of sub node, maximum host nodes can be managed 254 node; Host node also can be formed the big net of 65000 nodes at most by the last layer network node control simultaneously.
(7) high safety, ZigBee provides three level security patterns, comprises no security settings, uses Access Control inventory (ACL) to prevent the symmetric cryptography that illegally obtains data and adopt Advanced Encryption Standard (AES 128), to confirm its security attribute flexibly.
(8) unlicensed band, ZigBee adopt DSSS at industrial science medical treatment (ISM) frequency range, 2.4GHz (whole world), 915MHz (U.S.) and 868MHz (Europe).
Description of drawings
Fig. 1 is the structural representation of the radio sensing network monitoring system that is used for wastewater treatment of the utility model embodiment.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
On the contrary, the utility model is contained any alternative, the modification of on the marrow of the utility model and scope, making, equivalent method and scheme by claim definition.Further, the utility model is had a better understanding in order to make the public, in hereinafter the details of the utility model being described, detailed some specific detail sections of having described.There is not the description of these detail sections can understand the utility model fully for a person skilled in the art yet.
Referring to Fig. 1, be depicted as a kind of structured flowchart that is used for the radio sensing network monitoring system of wastewater treatment, comprise at least one road water quality parameter detector 101; Water quality testing meter 101 is used to detect the water quality condition parameter, comprises flow, water temperature; PH, ammonia nitrogen etc. need carry out monitoring parameter.Every road water quality testing meter 101 and corresponding ZigBee terminal 102 connect, with the ZigBee telegon 200 of ZigBee terminal 102 wireless connections, and the host computer that is connected through the RS232 communication interface with said ZigBee telegon 200.After ZigBee terminal 102 added the ZigBee network, ZigBee telegon 200 distributed one 16 the network address to give ZigBee terminal 102, and the network address and ZigBee telegon 200 that ZigBee terminal 102 usefulness are 16 communicate.Each ZigBee node is formed a star network, and ZigBee telegon 200 is centers of whole network, communicates through serial ports and host computer; ZigBee terminal 102 be distributed in ZigBee telegon 200 around, can not direct communication between each ZigBee terminal 102, can only carry out direct communication with ZigBee telegon 200.Each ZigBee terminal 102 node is responsible for coming the data acquisition of water quality parameter detector 101; Send to ZigBee telegon 200 through wireless signal again; And ZigBee telegon 200 is collected the data that each ZigBee terminal 102 nodes send, and passes to host computer 300 to data through RS232 communication again.Certainly, host computer 300 and ZigBee telegon 200, ZigBee telegon 200 and ZigBee terminal 102, their communication is mutual.Thereby; Host computer 300 can send order and give ZigBee telegon 200; Give each ZigBee terminal 102 node through ZigBee telegon 200 forward commands again, make total system not only can realize data transmission from bottom to top, also can realize the top-down transmission of data.
