Description
Technical field
The present invention relates to detecting system, is specifically whether a kind of rainy day water detection well lid opens system.
Background technology
In each big city in the whole nation, ponding of the rainy day due to road surface, the drainability deficiency of sewer form product together
Water, causes the lower section of gully due to the relation of hydraulic pressure, and hydraulic pressure is upspring by well lid or even bullet flies, and due to the ponding on road surface, road
People can not obtain at the first time the information blindness of road conditions paddle traveling be it is extremely dangerous, lack well lid caused by passerby without
The injured or even lethal accident of guilt occurs again and again, so invention is a kind of to find well lid displacement in time, and judges whether well head also has
Well lid, then sending the system of alarm and reminding passerby is extremely necessary.
The content of the invention
Present invention aim to address the above problem, there is provided whether a kind of rainy day water detection well lid opens system.
The purpose of the present invention is accomplished by the following way：
Whether a kind of rainy day water detection well lid opens system, including start-up circuit and hydraulic pressure detection circuit and angle detection electricity
Road；The start-up circuit is parallel resistive circuit, for detecting whether well lid moves, under the hydraulic pressure detection circuit detection well lid
Side whether there is hydraulic pressure value；The angle detection circuitry is used to detect the angle value between well lid and the borehole wall, when system starts, when
When well lid is moved, the parallel resistance of start-up circuit sends change, and parallel resistance becomes series resistance, resistance value increase so as to
Cause current value to change and diminish, processor starts hydraulic pressure detection circuit according to the change of current value, confirms below well lid
With the presence or absence of water pressure, if there are water pressure, start angle detection circuitry, detect the angle between drainage manhole cover and the borehole wall, row
When angle between well cover and the borehole wall is more than set threshold value, processor starts alarm alarming device.
The parallel resistance being made of in circuit two same resistances, one of resistance are to remove, what that was removed
Resistance there is a cord one to be connected with resistance, the well lid of other end and draining well head is connected with each other, so when well lid is sent out
When raw displacement, the circuit that can drive that can remove leaves, and the parallel resistance of script can become series resistance, so electric
Resistance value will increase, and in the case where magnitude of voltage is constant, current value will reduce.
When current value reduces, processor will start hydraulic inductor, and whether sensing well head has hydraulic pressure at lower section, so
Whether it may determine that because rainy day ponding excessively causes hydraulic pressure by the open-top well lid displacement caused by of the well lid of top.
When lower section is there are when hydraulic pressure, the angle inductor that processor can be upward by well lid is powered, such as
If fruit does not detect that there is magnitude of voltage in top, judge that angle inductor may damage, thus across-the-line starting alarm, such as
Square degree inductor works normally on fruit, then the angle value detected between well lid and the borehole wall is how many, during if more than 180 degree, then
Judging well lid, position is out of well head, not at the place of well head, if judging well lid also at well head when being less than 180.
Specific implementation steps are such：
（1）The current value at the resistance value circuit both ends of parallel resistance is obtained, the initial current value that system starts is normal current value, when
Current value reduces, calculate reduce current value if 0.5 times or so of normal current value current value when, judge top well lid generation
Displacement, current value is sent to processor；
（2）Start hydraulic inductor, whether there is hydraulic pressure below detection well head, start well head if well head lower section is there are hydraulic pressure value
The angle inductor of lid, there is no return to step if hydraulic pressure value below well head（1）；
（3）The upward square degree of processor be powered and the voltage at detection angles detection circuit both ends, if can not detection angles
The magnitude of voltage of inductor then starts alarm；
（4）Angle inductor detects the angle value between well lid and the borehole wall, is returned if angle value judges well lid displacement less than 180 degree
To step（2）If angle value is more than 180 degree, manhole cover loss is judged, then processor starts alarm alarming device.
The beneficial effects of the invention are as follows：
1. the change of electric current is caused to judge that top well lid whether there is displacement by the change of resistance；
2. judge whether well lid has the possibility washed open by hydraulic pressure with the presence or absence of hydraulic pressure value by hydraulic pressure sensor detection lower section；
3. whether the angle value that well lid and well head are detected by angle inductor judges well lid also at well head.
