In recent years, with aquaculture scale, the continuous improvement of intensive degree, increasing and cultivating close for type is cultivated
The increase of degree, Cultivated water aquatic environment deteriorate increasingly, and disease incidence is higher and higher, thus cause fish quality and ask
Topic also becomes increasingly conspicuous.Demand of water quality monitoring technology during breeding production improves increasingly, with the continuous promotion of technology, from
Initial artificial acquisition water sample measures in laboratory again, gradually develops to and installs the online prison that sensor carries out water quality in pond
It surveys.Existing water quality online measuring technique (PLC patterns, ZigBee patterns, GPRS patterns, 3G patterns) solves to a certain extent
The problem of water quality monitoring, control.But PLC patterns need to arrange that circuit, maintenance cost are larger.General on-line monitoring equipment is used
It is worked normally in the case of unattended, and GPRS, 3G, 4G transmission technology belong to the wireless communication of highly energy-consuming, powerup issue
Prodigious restriction is received, also is difficult to ensure normal operation when cloudy weather for several days running weather using solar energy and accumulator.
In in June, 2016 frozen standard NB-IOT technologies are excellent with its framework, covering is wide, low in energy consumption, at low cost super more
Advantage becomes global operator, the strategic direction that science-and-technology enterprise is actively laid out.NB-IOT covers gain 20Db than existing network,
Overlay area promotes 100 times；Has the ability of support magnanimity connection, a sector can support 100,000 connections, support low prolong
When susceptibility, ultralow equipment cost, low equipment power dissipation and optimization the network architecture；NB-IOT terminal standby times are 10
Year, module expected cost is far below existing transmission module.
When NB-IOT technologies are applied in aquatic products monitoring, main technology barrier is：
The transport protocol of 1.NB-IOT uses UDP technologies, which provides connectionless communication service, therefore has and lose
Packet phenomenon.
2.NB-IOT communications modules can not receive the configuration information and other information that server issues in PSM states.
Therefore, NB-IOT technologies can be not yet applied in aquatic products monitoring at present.

After device, the response of server was monitored using 7 second time.After server receives water quality information, the confirmation with " OK " is sent immediately
Information.Water quality monitoring module as gateway can determine whether to send successfully after receiving confirmation message.If the water quality as gateway
Monitoring modular does not receive feedback information in 7 seconds, that is, starts second of UDP transmission.When 3 UDP transmission do not receive feedback letter also
Breath, that is, abandon the breath of notifying.
In addition, the management for the ease of server background to distributed aquaculture monitoring device, the water quality as gateway is supervised
The NB-IOT communications modules for surveying module need to be periodically COMMECT states from PSM state activations.Mould is communicated in view of NB-IOT
Group enters PSM states in 200 seconds that no data interacts, and distributed aquaculture monitoring device acquiescence acquires water quality information
Period is 20 minutes.Server is reduced by way of microcontroller Periodic activation issues configuration information and other information
Stand-by period.Concrete mode is：Water quality monitoring module as gateway is in the time of PSM states in NB-IOT communications modules
It is interior, one query information was sent to server by NB-IOT communications modules in every 7 minutes, whether inquiry server has corresponding distribution
The configuration information and other information of formula aquaculture monitoring device.
Pass through above-mentioned technological means so that NB-IOT technologies can be applied in aquatic products monitoring, to obtain low-power consumption, low
The technical advantages such as cost.
