DETAILED DESCRIPTION

[0056] In order to explain the technical content, the purpose and effect of the utility model in detail, the following is explained in combination with the embodiment and the accompanying drawings.

[0057] The embodiment of the utility model provides a pipe network monitoring terminal with image acquisition function, including main control module, first monitoring component, second monitoring component and camera component;

[0058] The first monitoring component and the second monitoring component are connected to the first end of the main control module;

[0059] The camera component is connected to the second end of the main control module;

[0060] The first monitoring component is used for detecting the real-time water level signal and real-time flow rate signal when the pipe water discharge does not reach the full pipe state;

[0061] The second monitoring component is used for detecting the real-time water level signal and real-time flow rate signal when the pipe water discharge reaches the full pipe state;

[0062] The camera component is used for collecting image information in the pipe.

[0063] From the above description, the utility model has the beneficial effect that the first monitoring component detects the water level and flow rate when the water discharge does not reach the full pipe state, and the second monitoring component detects the water level and flow rate when the water discharge does not reach the full pipe state, which realizes the comprehensive monitoring of the real-time water level and flow rate signal under different water discharge states in the pipe, makes up for the defects of single sensor, and improves the flexibility of monitoring. At the same time, the main control module connects the camera component to collect image information in the pipe, and the sensor data can accurately extract and identify the flow data in the pipe, thereby improving the accuracy of monitoring.

[0064] Further, the first monitoring assembly comprises a radar water level sensor and a radar flow rate sensor;

[0065] The radar water level sensor and the radar flow rate sensor are both connected to the first end of the main control module;

[0066] The radar water level sensor is used to detect the real-time water level signal when the pipe water discharge does not reach the full pipe state;

[0067] The radar flow rate sensor is used to detect the real-time flow rate signal when the pipe water discharge does not reach the full pipe state.

[0068] From the above description, it can be seen that the first monitoring assembly adopts a radar water level sensor and a radar flow rate sensor, which can accurately detect real-time water level and flow rate signals when the pipe water discharge does not reach the full pipe state. The radar water level sensor measures the water level by emitting radar waves and receiving the reflected signals in the non-full pipe state. The radar waves are reflected when they encounter the water surface, and the sensor determines the distance of the water level by calculating the time difference between the emitted and received signals. In the non-full pipe state, the water surface is relatively calm and not limited by the top of the pipe, so the radar water level sensor can more accurately measure the water level. The radar flow rate sensor measures the flow rate by emitting radar beams and receiving the reflected signals from the scattering bodies (such as particles, bubbles, etc.) in the water flow in the non-full pipe state. In the non-full pipe state, the space inside the pipe is relatively large, and the scattering bodies in the water flow are more evenly distributed, which helps the radar flow rate sensor to more accurately capture the reflected signals.

[0069] Further, the second monitoring assembly comprises a pressure water level sensor and a Doppler flow rate sensor;

[0070] The pressure water level sensor and the Doppler flow rate sensor are both connected to the first end of the main control module;

[0071] The pressure water level sensor is used to detect the real-time water level signal when the pipe water discharge reaches the full pipe state;

[0072] The Doppler flow rate sensor is used to detect the real-time flow rate signal when the pipe water discharge reaches the full pipe state.

[0073] As can be known from the above description, the second monitoring assembly adopts a pressure water level sensor and a Doppler flow rate sensor, can accurately detect real-time water level and flow rate signals when the pipe discharge reaches a full pipe state, and ensures the stability of monitoring. The pressure water level sensor indirectly determines the water level height by measuring the static pressure generated by the water column in the pipeline on the sensor in the full pipe state. Therefore, the pressure water level sensor can accurately measure the water level. The Doppler flow rate sensor measures the water flow rate by using the principle of Doppler effect in the full pipe state. The sensor emits a beam of ultrasonic waves, which scatters when encountering suspended particles or bubbles in the water flow. Part of the scattered waves returns to the sensor at different frequencies. By analyzing the frequency change of these scattered waves, the speed of the water flow can be calculated. In the full pipe state, the Doppler flow rate sensor is usually installed inside the pipeline, which can ensure that the ultrasonic waves can fully interact with the suspended particles or bubbles in the water flow, so as to more accurately obtain the scattered waves and improve the accuracy of flow rate calculation.

[0074] Further, the camera assembly includes a processing chip, a camera, a fill light, and a super-photoluminescence image sensor.

[0075] The processing chip is connected to the second end of the main control module, the camera is connected to the super-photoluminescence image sensor, and the fill light and the super-photoluminescence image sensor are both connected to the processing chip.

[0076] As can be known from the above description, the camera assembly added in the terminal includes a processing chip, a camera, a fill light, and a super-photoluminescence image sensor, which can realize high-definition shooting in the pipe network environment to identify pipe network foreign objects and illegal discharge behaviors in cooperation with related artificial intelligence algorithms, and improve the intelligent level of monitoring.

[0077] Further, it further includes a self-organizing network communication module.

[0078] The self-organizing network communication module is connected to the third end of the main control module.

[0079] The self-organizing network communication module is used for sending the real-time water level signals and real-time flow rate signals collected by the first monitoring assembly or the second monitoring assembly to a central server.

[0080] As can be known from the above description, the application of the self-organizing network communication module enables the monitoring terminal to send the collected real-time water level and flow rate signals to the central server, realizes remote transmission and centralized management of data, and improves the monitoring efficiency.

[0081] Further, it further includes a mobile communication module.

[0082] The mobile communication module is connected to the fourth end of the main control module.

[0083] The mobile communication module is used for sending the real-time water level signal and the real-time flow rate signal collected by the first monitoring component or the second monitoring component to the central server when the ad hoc network communication module cannot be used.

[0084] From the above description, the standby of the mobile communication module ensures that the monitoring data can be sent to the central server when the ad hoc network communication module cannot be used, and the reliability and stability of the monitoring system are enhanced.

[0085] Further, the power supply module is further included;

[0086] The power supply module includes a lithium battery pack and a voltage conversion circuit;

[0087] The lithium battery pack is connected to the input end of the voltage conversion circuit, and the output end of the voltage conversion circuit is connected to the main control module, the first monitoring component and the second monitoring component respectively.

[0090] The input end of the communication interface circuit is connected to the first monitoring component and the second monitoring component respectively, and the output end of the communication interface circuit is connected to the first end of the main control module.

[0091] From the above description, the setting of the communication interface circuit enables the first monitoring component and the second monitoring component to smoothly transmit the collected data to the main control module, and improves the efficiency and accuracy of data transmission.

[0092] Further, the voltage conversion circuit includes a direct current conversion chip, a fuse, a first transistor, a first capacitor, a second capacitor and a first inductor;

[0093] One end of the fuse is connected to the lithium battery pack, and the other end of the fuse is connected to the first terminal of the first transistor, and the second terminal of the first transistor is connected to the input end of the direct current conversion chip, one end of the first capacitor and one end of the second capacitor respectively;

[0094] The third terminal of the first transistor, the other end of the first capacitor and the other end of the second capacitor are all grounded;

[0095] The output end of the direct current conversion chip is connected to one end of the first inductor, and the other end of the first inductor is connected to the main control module, the first monitoring component and the second monitoring component respectively.

[0096] From the above description, it can be known that the fuse is used for protecting the whole circuit to prevent the circuit components from being damaged due to excessive current; the first transistor is used for preventing the circuit from being damaged by battery reverse connection or reverse current; the first capacitor and the second capacitor are used as filter capacitors to smooth the voltage provided by the battery and remove high-frequency noise and fluctuations; the DC conversion chip is used for reducing the high voltage of the battery to the low voltage required by the module; the first inductor performs filtering to ensure the smoothness and stability of the output voltage. The voltage conversion circuit can ensure the stability and safety of the power supply module and prolong the service life of the monitoring terminal.

[0097] Further, the communication interface circuit comprises a communication interface chip, a first resistor, a second resistor, a third resistor, a fourth resistor, a first Zener diode and a second Zener diode;

[0101] The other end of the fourth resistor is connected to the negative electrode of the second Zener diode and the first end of the master control module respectively, and the positive electrode of the second Zener diode is grounded.

[0102] From the above description, it can be known that the first resistor to the fourth resistor are used for reducing the reflection of signals in the transmission process to ensure that the signals can be stably and accurately transmitted; the two Zener diodes are used for realizing voltage protection, when the output voltage is too high, the Zener diode will be turned on to discharge the excess voltage to the ground, thereby protecting the circuit from damage caused by voltage spikes; the communication interface chip is used for providing various communication interfaces and functions. The communication interface circuit can protect the transmission signals from interference and damage, and improve the reliability and accuracy of data transmission.

[0103] The pipe network monitoring terminal with the image acquisition function provided by the utility model can be applied to the monitoring and acquisition scene of fluid parameters in a pipeline, and the following will be illustrated by specific embodiments:

[0104] Please refer to Figures 1 to 7 The embodiment one of the utility model discloses:

[0105] As Figure 1As shown in the figure, a pipe network monitoring terminal with image acquisition function comprises a main control module 1, a first monitoring component 2, a second monitoring component 3 and a camera component 6; the first monitoring component 2 and the second monitoring component 3 are both connected to the first end of the main control module 1; the camera component 6 is connected to the second end of the main control module 1; the first monitoring component 2 is used to detect real-time water level signals and real-time flow rate signals when the pipe is not full; the second monitoring component 3 is used to detect real-time water level signals and real-time flow rate signals when the pipe is full; the camera component 6 is used to acquire image information in the pipe.

[0106] As shown in the figure, specifically, the first monitoring component 2 comprises a radar water level sensor 21 and a radar flow rate sensor 22; the radar water level sensor 21 and the radar flow rate sensor 22 are both connected to the first end of the main control module 1; the radar water level sensor 21 is used to detect real-time water level signals when the pipe is not full; the radar flow rate sensor 22 is used to detect real-time flow rate signals when the pipe is not full. Figure 2 Specifically, the second monitoring component 3 comprises a pressure water level sensor 31 and a Doppler flow rate sensor 32; the pressure water level sensor 31 and the Doppler flow rate sensor 32 are both connected to the first end of the main control module 1; the pressure water level sensor 31 is used to detect real-time water level signals when the pipe is full; the Doppler flow rate sensor 32 is used to detect real-time flow rate signals when the pipe is full.

[0107] It should be noted that the radar water level sensor 21 of the first monitoring component 2 and the pressure water level sensor 31 of the second monitoring component 3 are installed at different positions of the pipe to be monitored. Since the radar water level sensor 21 realizes water level monitoring through the reflection of radar waves when they encounter the water surface, which is a non-contact measurement, the radar water level sensor 21 should be installed on the top outside the pipe to be monitored, such as under the manhole cover or on the fixed bracket on the side of the pipe, to ensure that the radar waves can be emitted vertically to the water surface and accurately reflected back to the receiver. The pressure water level sensor 31 realizes water level monitoring through the static pressure generated by the liquid, which is a contact measurement, so the pressure water level sensor 31 should be installed at the bottom inside the pipe to be monitored, such as fixed on the pipe to be monitored through the installation bracket.

[0108]

[0109] ​It should be noted that the radar flow sensor 22 of the first monitoring assembly 2 and the Doppler flow sensor 32 of the second monitoring assembly 3 are installed at different positions of the pipeline to be monitored. Since the radar flow sensor 22 measures the flow rate by emitting radar waves and receiving the reflected signals thereof, it is usually installed above or beside the pipeline to ensure that the radar waves can be smoothly emitted and reflected back to the receiver without excessive interference from other objects in the pipeline. The Doppler flow sensor 32 measures the flow rate by utilizing the Doppler effect of ultrasonic waves in the fluid, and thus is usually installed inside the pipeline to accurately capture the reflection and frequency change of the ultrasonic waves.

[0110] As can be seen from the above description, the first monitoring assembly 2 is arranged outside the pipeline to be monitored, and the second monitoring assembly 3 is arranged inside the pipeline to be monitored. The combination of the first monitoring assembly 2 and the second monitoring assembly 3 compensates for the defects of a single water level monitoring sensor, so that the terminal can still accurately collect the water level depth and flow rate even in the case of water level overflow in the connected wellhead to form waterlogging, and can effectively monitor the degree of waterlogging.

The output terminal of the DC-DC converter chip U2 is connected to one end of the first inductor L1, and the other end of the first inductor L1 is connected to the main control module 1, the first monitoring component 2, and the second monitoring component 3, respectively.

The other end of the first inductor L1 is connected to one end of resistors R3 and R2, and one end of capacitor C6. The other end of resistor R3 is connected to the indicator pin PG of the DC-DC converter chip U2. The other end of resistor R2 is connected to one end of resistor R1 and the feedback output pin FB of the DC-DC converter chip U2. The other end of resistor R1 and capacitor C6 are grounded. In this way, resistors R1, R2, and R3 form a voltage divider circuit, feeding a portion of the output voltage back to the DC-DC converter chip U2. The comparator inside the DC-DC converter chip U2 compares the voltage on the FB pin with the reference voltage, thereby adjusting the output voltage and ensuring the stability and accuracy of the output voltage.

[0113] like Figure 6 As shown, this terminal also includes resistors R5 and R6, a PMOS transistor Q2, a transistor Q3, and a fuse F3. The source of PMOS transistor Q2 is connected to the 7.2V supply voltage output by the voltage conversion circuit 41 and one end of resistor R5. The drain of PMOS transistor Q2 is connected to one end of fuse F3, and the other end of fuse F3 is connected to the first monitoring component 2 and the second monitoring component 3VSNR. The gate of PMOS transistor Q2 is connected to the other end of resistor R5 and the collector of transistor Q3. The base of transistor Q3 is connected to one end of resistor R6, and the other end of resistor R6 is used to connect to the monitoring power control signal PWRVH of the main control module 1. The emitter of transistor Q3 is grounded. In this way, resistors R5 and R6, PMOS transistor Q2, transistor Q3, and fuse F3 constitute a monitoring power control circuit. The power control signal PWRVH controls the conduction of transistor Q3, thereby controlling the switching of PMOS transistor Q2.

[0114] Specifically, the terminal further comprises a communication interface circuit 5; the input ends of the communication interface circuit 5 are connected with the first monitoring component 2 and the second monitoring component 3 respectively, and the output end of the communication interface circuit 5 is connected with the first end of the master control module 1.
