Example two:
the second embodiment is added with the following contents on the basis of the first embodiment:
the intelligent flap valve detection alarm device also comprises a water level sensor arranged in the flap valve;
the water level sensor is used for detecting the water level height of the drainage pipe at the river side in real time and transmitting the water level height to the detection equipment.
Specifically, the device can also monitor the water level height of the river side drain pipe in real time through the water level sensor. The following provides three conditions for controlling the opening or closing angle of the flap valve according to the water level height of the drainage pipe at the edge of the river.
First, referring to fig. 4, the detection apparatus is specifically configured to:
s1: receiving a flap valve opening state table input by a user, wherein the flap valve opening state table comprises a plurality of groups of data, and each group of data comprises water level height, flap valve opening angle and opening time; the opening time is the time required by the flap valve from the complete closing and the opening to the corresponding flap valve opening angle;
specifically, the flap valve opening state table stores flap valve opening angles corresponding to different water level heights in the drainage pipe at the river side, for example: when the water level in the drainage pipe at the river side is lower than the water level 1, the flap valve is opened 1/4; when the water level in the drainage pipe at the river reaches the water level 2, the flap valve is opened 1/2; when the water level in the drainage pipe at the river side is higher than the water level 3, the flap valve is fully opened. Wherein the water level is more than 1 and more than 2 and more than 3. The corresponding opening time is the time required for the flap to open from fully closed to 1/4, 1/2 or fully open.
S2: when the water level height uploaded by the water level sensor is received, judging whether the water level height reaches the water level height in any group of data in the flap valve opening state table;
s3: if yes, obtaining the flap valve opening angle in the group of data in the flap valve opening state table, and starting a timer; the opening angle of the flap valve is transmitted to a flap valve driver, and the flap valve driver is used for controlling the flap valve to be opened to a corresponding angle;
specifically, the detection device can judge whether the water level in the drainage pipe at the river side reaches the water level defined in the flap valve opening state table or not in real time, and when the water level reaches the water level, the flap valve is controlled to be opened to a corresponding angle through the flap valve driver. The device can control the flap valve to be opened to different angles according to different water levels in the drainage pipe at the edge of the river.
S4: and when the timing of the timer reaches the opening time in the group of data, reading the optical signal output by the optical module, and recording the opening fault of the flap valve when the opening angle of the flap valve obtained according to the optical signal is inconsistent with the opening angle of the flap valve in the group of data.
Specifically, the detection device starts a timer to count time while controlling the flap valve to be opened, and judges whether the flap valve is opened to a corresponding angle or not when the counted time is up. For example, if the flapper needs Amin when the flapper is opened 1/4, 2Amin when the flapper is opened 1/2, and 4Amin when the flapper is completely opened, when the flapper needs to be controlled to be opened 1/4, and the timing time of the timer reaches Amin, the optical signal output by the optical module is read, the current angle at which the flapper is opened is identified, if the angle at which the flapper is opened is 1/4, it is indicated that the flapper can be normally opened, and if the angle at which the flapper is opened is greater than or less than 1/4, it is indicated that the flapper is open in failure, and the flapper cannot be opened according to the preset angle.
Secondly, referring to fig. 5, the detection device is specifically configured to:
s11: when the water level height uploaded by the water level sensor reaches the water level height in a group of data in a flap valve opening state table, reading an optical signal output by the optical module, calculating according to the optical signal to obtain the opening angle of the flap valve, searching a group of data in the flap valve opening state table, which is consistent with the opening angle of the flap valve, defining the group of data as a previous group of data, and defining the opening time in the previous group of data as first opening time;
specifically, during use of the flap valve, it may occur that when the previous water level of the river side drain reaches level 1, the flap valve is opened 1/4. As the water level in the river side drain pipe becomes higher and higher, the water level in the river side drain pipe reaches the water level 2, and the flap valve is controlled to open 1/2. At this time, the flap valve does not need to be controlled to be opened to 1/2 after being completely closed. The flap door is directly controlled to open from 1/4 to 1/2.
S12: acquiring a group of data corresponding to the current water level height in a flap valve opening state table, defining the group of data as current group data, acquiring opening time in the current group data, defining the opening time as second opening time, and starting a timer; transmitting the opening angle of the flap valve in the current group of data to a flap valve driver, and controlling the flap valve to be opened to a corresponding angle by using the flap valve driver;
specifically, when the flap valve is controlled, the optical signal output by the optical module is read first, the opening angle is determined, and then according to the expected opening angle of the flap valve at this time, how many more angles (i.e. the difference between the two angles) the flap valve needs to be closed are calculated to achieve the expected angle.
Since the opening time is the time after the flap door is opened at a certain angle from the full closing, in this case, the flap door is not opened at a certain angle from the full closing, but is opened at an angle a to an angle B. Therefore, the opening time of the flap valve at this time is the difference between the opening times corresponding to the two angles.
S13: and when the timing of the timer reaches the difference value between the second starting time and the first starting time, reading an optical signal output by the optical module, and recording the opening fault of the flap valve when the opening angle of the flap valve obtained according to the optical signal is inconsistent with the opening angle of the flap valve in the current group of data.
Specifically, when the timer counts time, it is only necessary to determine whether the timing time of the timer reaches the difference between the two opening times, if so, read the optical signal output by the optical module, determine whether the opening angle of the flap valve reaches an expected angle, and if so, indicate that the flap valve is normal. If not, it indicates the flap door opening fault.
Thirdly, referring to fig. 6, the detection device is specifically configured to:
each group of data in the flap valve opening state table further comprises closing time;
s21: when the water level uploaded by the water level sensor is lower than the water level in the current group of data and reaches the water level in the other group of data in the flap valve opening state table, defining the closing time in the current group of data as first closing time, defining the other group of data as next group of data, and defining the closing time in the next group of data as second closing time;
s22: starting a timer; generating a closing instruction and transmitting the closing instruction to a flap valve driver, and controlling the flap valve to be closed to the flap valve opening angle in the next group of data by using the flap valve driver;
s23: and when the timing of the timer reaches the difference value between the first closing time and the second closing time, reading an optical signal output by the optical module, and recording a closing fault of the flap valve when the opening angle of the flap valve obtained according to the optical signal is inconsistent with the opening angle of the flap valve in the next group of data.
Specifically, when the water level in the drainage pipe at the side of the river drops to a level lower than the level corresponding to the current flap valve opening angle but still higher than the level lower by one level, the flap valve needs to be controlled to close from the current opening angle to the opening angle lower by one level. For example, when the water level in the drainage pipe at the river side drops from the water level 2 to the water level 1, the flap valve needs to be controlled to be closed from 1/2 to 1/4.
Therefore, the detection equipment respectively obtains the opening time and the water level height difference corresponding to the two water level heights. And starting a timer for timing, reading the optical signal output by the optical module again when the timing time of the timer reaches the difference between the two opening times, and judging whether the closing angle of the flap valve reaches an expected angle.
