Trigger modes of warning, continuous monitoring pattern, O&M patrol mode.
Smaller in daily fair weather or rainfall, in catch-basin in the normal situation of liquid level, master controller closes all
Perception and monitoring function are daily suspend mode.
As shown in Fig. 1 ~ 3, a kind of Intelligent rainwater well lid based on the NB-IoT communication technology, including caping, lid, and lid
Bottom, caping are equipped with maintenance lifting hole 1, illumination sensing hole 2, rainwater inflow hole 3, include overcurrent chamber 4, induction cavity 5, intelligence in lid
6 three functional chambers of chamber, the well lid base are made of the mechanical reverse turning bed structure of band and entity partition-type structures.Wherein overcurrent bottom of chamber portion is
Have the mechanical turnover panel of mechanical return function, the circle that the machinery turnover panel includes mechanical rotating shaft 9 and is fixed on mechanical rotating shaft 9
Thin plate 10, mechanical turnover panel are equipped with matched limit sensors, are equipped with light sensor, liquid level sensor, rain in induction cavity
The caping inflow hole of well cover is directly communicated with lid overcurrent chamber, and overcurrent bottom of chamber portion is the turnover panel for having mechanical return function, can
According to the angle of the big minor adjustment turnover panel for the rainfall that becomes a mandarin.When not having rainfall or smaller rainfall, only a small amount of rainwater is by becoming a mandarin
Hole enters well lid overcurrent chamber, and overcurrent bottom of chamber portion turnover panel is not opened or opening angle is smaller, and well lid master controller is stopped in low-power consumption
Sleep mode, without monitoring and communicating.
When rainfall is larger or has a large amount of rainwater to enter overcurrent chamber, 4 bottom mechanical turnover panel of overcurrent chamber is by rainwater gravity
When unlatching reaches a certain position, trigger pulse is generated by limit sensors, after master controller receives the pulse signal, by daily
Suspend mode enters triggering modes of warning.
As shown in Figure 1, the caping illumination sensing hole of catch basin cover logical 2 crosses transparent wear glass and extraneous closing, its underpart
It is directly communicated with induction cavity, light sensor can perceive ambient weather situation according to the light luminance that environment is projected.
Threshold value, while clock chip of arranging in pairs or groups are incuded according to the light luminance situation of change setting under the daily fair weather in well lid position
Differentiated.
In the case that specific logic is, is daytime when the time, and ambient brightness is substantially reduced, touching is generated by light sensor
Pulse is sent out, after master controller receives the pulse signal, triggering modes of warning is entered by daily suspend mode.
As shown in Figure 1, liquid level sensor is arranged in catch basin cover induction cavity bottom, liquid level sensor is externally provided with sealed envelope
Layer can carry out alarm and continuous monitoring to liquid level in well, and control and alarm liquid level can be according to daily liquid levels in the catch-basin of place
Situation gives field calibration, and control related to the present embodiment and alarm liquid level are respectively L1, H1, L2, H2 from low to high,
In, liquid level sensor at least has two liquid level warning outputs of H1, H2.
As shown in figure 3, trigger pulse is generated by liquid level sensor when liquid level is increased to alarm liquid level H1 in catch-basin,
After master controller receives the pulse signal, triggering modes of warning is entered by daily suspend mode.
When master controller enters triggering modes of warning, liquid level sensor enters Timing measurement operating condition, and (timing cycle is generally
30 ~ 60min is adjustable), measured liquid level data carries out record storage by master controller and passes through the timing of NB-IoT communication module
It is sent to remote server.
When continuous 3 sampling periods (periodicity is adjustable) are respectively positioned on alarm liquid level L1 or less, master controller is by triggering
Modes of warning enters daily suspend mode.
When master controller enters triggering modes of warning, and liquid level still persistently increases and reaches alarm liquid level H2 in well, by
Liquid level sensor generates trigger pulse, after master controller receives the pulse signal, enters continuous monitoring mould by triggering modes of warning
Formula, liquid level sensor continuously measure liquid level in well, and master controller leads to alarm signal and the liquid level data surveyed by NB-IoT
Letter module is sent directly to remote server.
When master controller enters continuous monitoring pattern, liquid level is controlled flood and drained flooded fields the starting of measure or outer due to correlation in catch-basin
When the reasons such as the reduction of portion's rainfall lead to that liquid level is reduced to L2 or less in well, it is pre- that master controller by continuous monitoring pattern enters triggering
Alert mode.
In addition to above-mentioned Three models, for convenient for daily operation management, master controller is in office there are also a kind of O&M patrol mode
In the case of what, municipal Storm Sewer Network operation maintenance personnel can remote server take timing with not timing by way of, utilize NB-
IoT communication module carries out inspection to the catch basin cover in institute's compass of competency, obtains the sensitive information of each Intelligent rainwater well lid.Together
When, patrol officer can also reach scene, and handheld reader reads the information of well lid electronic tag, know the specific of well lid instantly
State.
