Cloud Server of the invention is controlled according to soil humidity information and water level information feedback control signal to dam flood discharge
Center specifically after Cloud Server receives water level information, water level information and calibrated altitude information is compared, if water level
Information is less than calibrated altitude information, illustrates that dam can operate at this time without flood discharge；Cloud Server receives soil moisture letter
After breath, soil humidity information and standard humidity information are compared, if soil humidity information is less than standard humidity information, illustrate dam
The ecological vegetable water shortage that the flood discharge region 105 in 88 downstreams is planted, even if dam can be operated without flood discharge, Cloud Server base
After above-mentioned comparing result, the first signal is fed back to dam flood discharge control centre to carry out flood discharge operation, to guarantee flood discharge region
105 ecological balance.As can be seen that the dam monitoring system of the invention based on lora is based on water level information and soil moisture is believed
Breath, to carry out flood discharge and water storage operation, so that the ecological balance in flood discharge region 105, is based on this overall monitor and this hair
The advantageous point that can guarantee the ecological balance of the bright dam monitoring system based on lora.
Dam monitoring method based on lora the following steps are included:
Water level information is sent to the third of lora gateway 30 by step S1, the first lora communication module of water level metering device 10
Soil humidity information is sent to lora gateway by the 2nd lora communication module of lora communication module, soil humidity detector 20
30 the 3rd lora communication module；
Soil humidity information and water level information are sent to Cloud Server 40, cloud by the wifi module 33 of step S2, lora gateway 30
Server 40 is according to soil humidity information and water level information feedback control signal to dam flood discharge control centre 50.
In the above-described embodiments, specific calculation is as follows:
Take precautions against drought strategy: soil moisture lower limit is Smin, daily waterdrainage amount be fixed as P, soil moisture S and current location water level and
The relationship of waterdrainage amount is S=f (P), and Pmin meets relationship Smin=f (Pmin), then Pmin is to meet soil moisture lower limit most
Low displacement.If moisture storage capacity is T0 on the day of reservoir, it is In that daily precipitation or other waters, which flow into the increased moisture storage capacity of channel, daily
Surplus water is Tn, and the number of days upper limit of taking precautions against drought that can be supported is M, since daily capacity reservoir has to be larger than 0, and daily displacement
Minimum displacement should be greater than, then the above variable should meet following relationship: Tn > 0；Tn=Tn-1 +In-P；Tm+Im > P；Connection
It closes and solves, if relation above has one or more solutions, minimum value is daily drought period displacement.If relation above is not deposited
It is solving, then it represents that moisture storage capacity and rainfall can not support the drought period more than M days, and guarantee as far as possible is not influenced early period by drought.Pmin
As daily drought period displacement.
Prevention waterlogging strategy: the soil moisture upper limit is Smax, and daily waterdrainage amount is fixed as P, soil moisture S and current location water
The relationship of position and waterdrainage amount is S=f (P), and Pmax meets relationship Smax=f (Pmax), then Pmax is to meet soil moisture lower limit
Highest displacement.If moisture storage capacity is T0 on the day of reservoir, it is In that daily precipitation or other waters, which flow into the increased moisture storage capacity of channel,
Daily surplus water is Tn, and the number of days upper limit of taking precautions against drought that can be supported is M, since daily capacity reservoir is necessarily less than capacity reservoir
Tmax, and daily displacement should be greater than minimum displacement, then the above variable should meet following relationship: Tn < Tmax；Tn=
Tn-1 +In-P；Tm+Im > P；P < Pmax；Joint solves, if relation above has one or more solutions, maximum value is
Daily flooded phase displacement.If there is no solutions for relation above, then it represents that drained with maintaining the displacement of soil moisture normal value
Capacity reservoir can not be made without departing from readjustment calculated relationship: Tn < Tmax；Tn=Tn-1 +In-P.Joint solve, by with
Co-relation can find out displacement value range, be minimized as flooded phase displacement.Meet soil since the value necessarily exceeds
The highest displacement Pmax of humidity lower limit, so the order for the alarm that discharges water is issued by server, via LoRa when opening a sluice gate and drawing out some water
Gateway passs on illumination early-warning lamp, and illumination early-warning lamp is switched to warning light bright light after receiving instruction, such as sends out a warning, concurrent responding
Report sound, prevents accident.
The above is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
