Referring to fig. 1 to 2, in accordance with a preferred embodiment of the present invention, an optical fiber type septic tank full monitoring device includes a tank body 1, a power module, a central processing unit, an alarm module, an NB-IoT module, and a signal acquisition device, where the signal acquisition device includes an optical fiber head 5 of an optical fiber sensor, and an optical fiber sensor with a detection distance of 0 to 15cm is adopted; the metal sleeve 4 is fixedly connected with the optical fiber head 5 of the optical fiber sensor in a threaded manner, the metal sleeve 4 is fixedly connected with a metal baffle 10 below the optical fiber head 5 of the optical fiber sensor, the part of the metal sleeve 4 outside the septic tank 6 is fixedly connected with a thread hole on the box body 1 in a threaded manner, the optical fiber head 5 of the optical fiber sensor is positioned above the septic tank 6, the rear end of the optical fiber head 5 of the optical fiber sensor is connected with one end of an optical fiber 3, the other end of the optical fiber 3 penetrates out of the septic tank cover 9 and then is connected with the optical fiber controller 2, the optical fiber 3 is positioned in the metal sleeve 4, the metal sleeve 4 is fixedly connected with the septic tank cover 9 through a fixing flange 8, two ends of the metal sleeve 4 are fixedly connected with the optical fiber head 5 of the optical fiber sensor and the box body 1 through threads respectively, an angle gamma is formed between the extension line of the bent central line of the end part of the metal sleeve 4 positioned in the septic tank 6 and the vertical downward direction, the angle gamma is more than 10 degrees and less than 80 degrees, and 30 degrees is selected in the embodiment; the power module is electrically connected with the central processing unit, the alarm module, the NB-IoT module and the optical fiber controller 2 and is fixedly installed in the box body 1, the metal sleeve 4 is made of corrosion-resistant stainless steel, and the part, located in the septic tank 6, of the metal sleeve 4 can rotate around the vertical direction at the bent connection part of the metal sleeve after the fixing flange 8 is removed.
As shown in fig. 1 to 3, assuming that the longest detection distance of the optical fiber head 5 of the optical fiber sensor is 15cm between the point M and the point N in the drawing, when the excrement 7 in the septic tank 6 is located at the height of the plane B-B, the optical fiber head 5 of the optical fiber sensor cannot detect signals, the signal acquisition device in fig. 3 cannot acquire signals, and the central processing unit does not perform subsequent actions; when excrement 7 in the septic tank 6 is located at the A-A plane height shown in figure 1, as mentioned above, the range of the optical fiber sensor 5 is 0-15 cm, the distance between the M point and the N point is 15cm, the optical fiber sensor optical fiber head 5 just detects signals, after the optical fiber sensor optical fiber head 5 detects the signals, the signals are transmitted to the optical fiber controller 2 through the optical fiber 3 located in the metal sleeve 4, in the process, the signals transmitted through the optical fiber 3 are optical signals, and only after being processed by the optical fiber controller 2, the optical signals are converted into electric signals to be transmitted to the central controller, so that the anti-interference capability is stronger; on the other hand, because the extension line of the central line of the bent end part of the metal sleeve 4 in the septic tank 6 has an angle γ with the vertical downward direction, the angle γ is greater than 10 ° and less than 80 °, in the embodiment, 30 ° is selected, as shown in fig. 2, according to the geometry:
∠α＝∠β＝90°-∠γ (1)
obtaining the angle gamma as 30 degrees according to the formula (1):
∠α＝∠β＝60°；
assuming that the detection direction of the optical fiber sensor 2 is a straight line, and the actual height of the excrement 7 in the septic tank 6 from the septic tank cover 9 is M, N, 15cm sin30 degrees is 7.5cm, that is, when the actual height of the excrement 7 is 7.5cm, the optical fiber sensor 5 detects a signal, and considering that the actual optical fiber sensor 2 is diffuse reflection, the height of the actual excrement 7 is slightly greater than 7.5cm, but certainly less than the distance between M, N; if excrement 7 just enters the septic tank 6 at this moment, the fluctuation of the upper plane of the excrement 7 is probably caused, and the excrement 7 is attached to the optical fiber head 5 to influence the measurement when the fluctuation is severe, and when the device of the application meets the situation, the baffle 10 can effectively block sundries splashed due to the fluctuation of the excrement 7 and protect the optical fiber head 5 of the optical fiber sensor.
Therefore, the problem that the optical fiber head of the photoelectric switch is touched by the fluctuation of the top of the excrement 7 due to the fact that the excrement 7 enters the septic tank 6 when the photoelectric switch is vertically installed and the measuring distance is short is solved by obliquely installing the optical fiber head 5 of the optical fiber sensor in the application; on the other hand, a photoelectric switch with a large measuring range can be selected to meet the requirement of short-distance measurement, so that the measurement sensitivity is improved.
After the optical fiber sensor 5 detects a signal, the signal is transmitted to the optical fiber controller 2 through the optical fiber 3 positioned in the metal sleeve 4, as shown in fig. 3, the optical fiber controller 2 transmits the signal to a central processing unit, the central processing unit can be an embedded microcontroller or other CPUs capable of executing logic control and communication functions, and the central processing unit can execute the next action of the septic tank 6 being full: the command alarm module executes an alarm action, and the alarm module is an alarm lamp or an alarm which can execute a logic command or a communication command of the central processing unit; meanwhile, the central processing unit transmits information to the rear-end server management platform through the NB-IoT module through NB-IoT network communication, the rear-end server management platform sends alarm information to the mobile phone terminal, when a person holding the mobile phone terminal receives the alarm information, workers can be arranged to clean the septic tank 6, and when the septic tank 6 is cleaned to be below the plane A-A in the picture 1, the alarm information is removed.
This application has the advantage:
(1) the optical fiber sensor is adopted for measurement, on one hand, the optical fiber sensor does not need to contact with excrement in a measured septic tank, on the other hand, extra mechanical action is not needed, and the service life is long;
(2) the design of the metal sleeve bending and the baffle below the optical fiber sensor overcomes the problem that the photoelectric switch is easy to be attached by excrement in the septic tank when being vertically installed, and meanwhile, the optical fiber head of the optical fiber sensor can rotate by 360 degrees in the septic tank, so that multi-angle detection is realized.
