[0041] One embodiment of the present invention provides a multi-monitoring water monitoring instrument, referring to Figures 1 to 7 ,include:

[0042] Shell 1;

[0043] Mainboard 2, fixed in the housing 1;

[0044] A power module 3 is electrically connected to the mainboard 2;

[0045] The sensor module 3 is electrically connected to the mainboard 2 and the power module 3 respectively. The sensor module 4 includes a contact electrode 41, a static pressure sensor 42 and an ultrasonic sensor 43;

[0046] The contact electrode 41 is installed at the bottom of the housing 1 and is used to detect the conductivity of rainwater;

[0047] The static pressure sensor 42 is installed at the bottom of the housing 1 and is used to detect the static pressure of accumulated water;

[0048] The ultrasonic sensor 43 is installed on the top of the housing 1 , and is used to detect the height of the housing 1 submerged by accumulated water.

[0049] This embodiment uses a variety of monitoring methods, which improves the sensitivity of water accumulation monitoring and can measure the depth of water accumulation in real time. At the same time, it can use different monitoring methods according to different water accumulation depths, reducing the energy consumption of the water accumulation monitor; the sensor module 4 is provided with three measurement methods. Specifically, the sensor module includes a contact electrode, a static pressure sensor 42 and an ultrasonic sensor 43, which are respectively fixed at different positions of the shell 1. When the water is at different depths, different sensors are triggered to measure the depth of water accumulation. The multi-monitoring mode water accumulation monitor adopts a fusion of multiple sensing technologies with high measurement accuracy. When dealing with different water accumulation monitoring scenarios, there are no false alarms or missed alarms, and the measurement method can be adjusted in real time according to different water accumulation conditions. When the water is shallow or there is no water accumulation, there is no need to start all measuring devices, thereby reducing power consumption and extending the service life of the water accumulation monitor. Specifically, a chamber is provided inside the shell 1, and the main board 2, power supply module 3 and sensor module 4 are all fixed in the chamber inside the shell 1. The main board 2 is electrically connected to the sensor module 4 and is used to receive and process the water accumulation detection data of the sensor module 4. The power supply module 3 is used to supply power to the main board 2 and the sensor module 4.

[0050] The sensor module 4 includes a contact electrode 41 , a static pressure sensor 42 and an ultrasonic sensor 43 . The contact electrode 41 , the static pressure sensor 42 and the ultrasonic sensor 43 are conventional technologies.

[0051] The end of the contact electrode 41 extends out of the outer surface of the shell 1. The contact electrode 41 determines whether there is water by measuring the conductivity of water using an electrode. The contact electrode 41 is provided with two contacts. When there is water in the contact electrode 41, the contacts are in contact with the liquid, thereby forming a closed circuit. Due to the presence of liquid, current can flow between the contacts. By measuring the magnitude of the current or the voltage drop, the conductivity of the liquid can be calculated. It should be noted that conductivity is an indicator of the ion concentration in the liquid, and the ion concentration is proportional to the conductivity of the liquid. When the conductivity of the liquid reaches the conductivity of water, the conductivity of the liquid is proportional to the conductivity of the liquid. When the rate is high, it is determined that there is water accumulation at that location. This design can also prevent non-aqueous liquids from splashing onto the contact electrode 41, causing misdetection. The static pressure sensor 42 is fixed to the bottom of the housing 1 and is used to detect the static pressure of the accumulated water. When the contact electrode 41 detects that there is accumulated water, it sends an electrical signal to the main board 2, and the main board 2 controls the static pressure sensor 42 to start. Conversely, when the contact electrode 41 detects that the accumulated water has subsided, it sends an electrical signal to the main board 2, and the main board 2 controls the static pressure sensor 42 to turn off. The static pressure sensor 42 is provided with a pressure detection device and measures the static pressure of the pressure detection device by measuring the accumulated water. The ratio of static pressure and density is used to calculate the liquid level height, and then the depth of the accumulated water is measured in real time and transmitted to the main board 2; the ultrasonic sensor 43 is fixed on the top of the shell 1. The ultrasonic sensor 43 is provided with an ultrasonic transmitting device and an ultrasonic receiving device. When the static pressure sensor 42 detects that the accumulated water height submerges the shell 1, the static pressure sensor 42 sends an electrical signal to the main board 2. The main board 2 controls the ultrasonic sensor 43 to start. The ultrasonic transmitting device transmits ultrasonic waves to the water surface and calculates the emission time point at the same time. The ultrasonic receiving device receives the ultrasonic waves reflected by the water surface and calculates the time difference between the two time points. The height of the ultrasonic sensor 43 from the water surface, that is, the height at which the accumulated water exceeds the shell 1, is calculated by the propagation speed and time difference of the ultrasonic signal in the water. Since the height of the ultrasonic sensor 43 from the ground is fixed, the depth of the accumulated water can be calculated in real time. It should be noted that the working power consumption of the contact electrode 41 for measuring conductivity is very small. When there is no water accumulation, the static pressure sensor 42 and the ultrasonic sensor 43 are in the off state, which greatly reduces energy consumption. When there is water accumulation, the measurement mode can be automatically adjusted according to the depth of the water, thereby improving the accuracy and sensitivity of the water accumulation monitor.

[0052] Further, refer to Figure 3 and Figure 4, there are multiple contact electrodes 41, and the multiple contact electrodes 41 are respectively arranged on the bottom and side of the shell 1. The end of the contact electrode 41 is passed through the shell 1, and the contact electrode 41 and the shell 1 are sealed to prevent rainwater from entering the inside of the shell 1 through the gap. One contact electrode 41 is passed through and located on the bottom surface of the shell 1. When water accumulates on the ground, the contact electrode 41 can directly contact the water and quickly monitor the water accumulation. The other contact electrode 41 is passed through and located on the side of the shell 1. When the depth of the water accumulates, the contact electrode 41 on the side can contact the water and send a signal to the main board 2, thereby warning that the depth of the water accumulates gradually increases. It should be noted that the contact electrode 41 can also be set only on the bottom surface of the shell 1. The bottom surface of the shell 1 is close to the ground and can first contact the water accumulation, so that the contact electrode 41 can detect water accumulation in time.

[0053] Furthermore, a plurality of contact electrodes 41 are provided on the side of the shell 1, and the plurality of contact electrodes 41 are arranged at intervals along the height direction of the shell 1. In this embodiment, a plurality of contact electrodes 41 are provided on the side of the shell 1, and the plurality of contact electrodes 41 are arranged at intervals along the height. By providing the contact electrodes 41 at different heights, detection can be performed at different water levels, thereby more accurately judging the depth of accumulated water. When the accumulated water level gradually rises, detection is started step by step, starting from the lowest electrode. In this way, accumulated water can be detected in the early stages and an early warning can be issued in time. In addition, the plurality of contact electrodes 41 can provide multiple measurement points, which helps to more accurately determine the location and depth of accumulated water. In addition, if there is only one contact electrode 41, it may be misjudged due to splashing water or other non-water accumulation factors. The plurality of contact electrodes 41 can reduce such misjudgments.

[0054] Furthermore, one end of the contact electrode 41 is connected to an electrode PCB 411, which is electrically connected to the mainboard 2. The electrode PCB 411 is fixed within the housing 1. When the contact electrode 41 detects liquid, the electrode PCB 411 can analyze the detection data to determine whether it is accumulated water and send an electrical signal to the mainboard 2. In this embodiment, the electrode PCB 411 is provided on both the side and bottom surfaces of the housing 1. One end of multiple contact electrodes 41 on the side of the housing 1 is connected to the same electrode PCB 411, which simplifies the internal wire space and enables the electrode PCB 411 to uniformly process data from multiple contact electrodes 41 at different heights on the side.

[0055] Further, refer to Figure 3 and Figure 7The housing 1 is provided with a receiving groove 11 for accommodating the static pressure sensor 42. The groove wall of the receiving groove 11 is provided with a water inlet hole 111 that passes through the housing 1. The pressure measuring end of the static pressure sensor 42 is opposite to the water inlet hole 111. The static pressure sensor 42 is provided with an air inflation tube 421 for balancing the air pressure. The shape of the receiving groove 11 is the same as that of the static pressure sensor 42. The static pressure sensor 42 is tightly fitted to the groove wall of the receiving groove 11, so that the accumulated water will not enter the interior of the housing 1. The bottom wall of the receiving groove 11 is provided with a water inlet hole 111. The accumulated water can enter the receiving groove 11 through the water inlet hole. The pressure measuring end of the static pressure sensor 42 is opposite to the water inlet hole 111, so that the static pressure sensor 42 can directly measure the pressure of the accumulated water. In this embodiment, there is a gap between the outer opening of the water inlet hole 111 and the outer surface of the bottom of the housing 1. This gap allows the accumulated water to flow into the water inlet hole 111 to prevent Blockage, the static pressure sensor 42 is provided with an inflation tube 421 for balancing the pressure at the end facing away from the water inlet hole 111, and the opening of the inflation tube 421 extends out of the receiving tank 11. When the accumulated water enters the receiving tank 11 from the water inlet hole 111, the air in the receiving tank 11 is discharged from the receiving tank 11 through the inflation tube 421, thereby balancing the air pressure in the receiving tank 11, thereby ensuring the accuracy of the static pressure sensor 42 in measuring the accumulated water pressure. It should be noted that in other embodiments, the static pressure sensor 42 can also be directly penetrated through the bottom surface of the shell 1, so that the static pressure sensor 42 can also directly measure the accumulated water pressure.

[0056] Furthermore, a sealing rubber ring 422 is sleeved around the outer peripheral wall of the static pressure sensor 42, and the sealing rubber ring 422 is in contact with the wall of the receiving groove 11. In this embodiment, a circumferentially closed annular groove is formed on the side peripheral wall of the static pressure sensor 42, and the sealing rubber ring 422 is sleeved within the annular groove and partially protrudes from the annular groove. After the sealing rubber ring 422 is sleeved, the static pressure sensor 42 is accommodated in the receiving groove 11. The sealing rubber ring 422 and the wall of the receiving groove 11 are tightly fitted along the circumference, thereby preventing accumulated water from entering the interior of the housing 1 through the gap between the static pressure sensor 42 and the wall of the receiving groove 11. It should be noted that in other embodiments, the static pressure sensor 42 and the wall of the receiving groove 11 can also be sealed by glue.

[0057] Further, refer to Figure 4 The power module 3 includes a battery 31, a wired charging assembly 32, and a wireless charging assembly 33. Both the wired charging assembly 32 and the wireless charging assembly 33 are electrically connected to the battery 31. The battery 31 can be a rechargeable lithium battery. The combination of the wired charging assembly 32 and the wireless charging assembly 33 provides the water accumulation monitor with multiple charging options, which not only improves battery life but also makes charging more convenient.

[0058] Further, refer to Figure 5The wired charging component 32 includes a charging terminal 321 passing through the housing 1 and a waterproof cover 322 detachably covering the charging terminal 321 , and a waterproof rubber ring 323 is provided between the charging terminal 321 and the housing 1 . The charging terminal 321 is electrically connected to the battery 31, and the battery 31 can be charged through the charging terminal 321. The waterproof cover 322 is detachable and covers the charging port of the charging terminal 321, thereby preventing rainwater from seeping into the charging terminal 321 and causing damage to it. In this embodiment, the waterproof cover 322 is threadedly connected to the charging terminal 321. When charging is required, the waterproof cover 322 is screwed, and the waterproof cover 322 rotates to disengage from the charging terminal 321. When charging is completed, the waterproof cover 322 is covered on the charging terminal 321 and screwed circumferentially. The waterproof cover 322 isolates the accumulated water outside the charging port of the charging terminal 321. A waterproof rubber ring 323 is provided on the side wall of the charging terminal 321. The charging terminal 321 is inserted into the housing 1. The waterproof rubber ring 323 is located between the charging terminal 321 and the housing 1 and seals the gap between the two.

[0059] In this embodiment, the wireless charging component 33 includes a wireless charging PCB 331 and a wireless charging receiving coil 332 that are electrically connected to each other. The wireless charging receiving coil 332 can cooperate with an external wireless charger and perform energy coupling and transmission through the principle of electromagnetic induction. When the wireless charger transmitting end coil generates a changing magnetic field, the wireless charging receiving end coil will sense this magnetic field and generate current, thereby realizing wireless energy transmission. The wireless charging PCB 331 can convert the AC energy received by the wireless charging receiving coil 332 into DC energy suitable for charging the battery 31, and the wireless charging PCB 331 is provided with a control chip and is used to control the charging of the wireless charging receiving coil 332 to prevent overcharging, overheating or short circuit.

[0060] Furthermore, the multi-monitoring waterlogging monitor also includes a communication system 5, which is connected to the mainboard 2 and transmits the detection data of the sensor module 4 to the monitoring platform in real time. After the sensor module 4 detects waterlogging, it transmits the data to the mainboard 2. The mainboard 2 processes the waterlogging data and transmits it to the monitoring platform in real time via the communication system 5. The communication system 5 enables personnel to remotely monitor water level, rainfall, video / image data, and other data in real time. When the waterlogging depth reaches the warning value, the communication system 5 sends a warning signal to the monitoring platform, allowing personnel to take timely emergency measures.

[0061] Further, refer to Figure 6The communication system 5 includes a mobile communication module 51 and a LoRa communication module 52. The mobile communication module 51 and the LoRa communication module 52 are both arranged on the main board 2. The communication system 5 also includes an antenna 53. The antenna 53 is used to receive and send wireless signals so that the water accumulation monitor can communicate with the remote monitoring platform. The mobile communication module 51 generally includes but is not limited to 4G and 5G networks. They are hardware components that realize data communication between the water accumulation monitor and the cellular network. The mobile communication module 51 is responsible for transmitting the water accumulation data collected by the sensor module 4, such as water accumulation depth, water accumulation rising speed and rainfall, to the remote monitoring platform through the wireless network for real-time monitoring and analysis. The LoRa communication module 52 uses spread spectrum technology to achieve long-distance transmission at lower power. Not only is the transmission distance long and the signal interference is small, but also the energy consumption is low. In this embodiment, the mobile communication module 51 and the LoRa communication module 52 are respectively located on both sides of the main board 2, and the two do not interfere with each other. The installer can choose to activate them according to the signal conditions of the installation point without having to disassemble and reinstall the communication module, which solves the time-consuming and labor-intensive problems caused by inconsistent communication conditions, improves installation convenience, and reduces installation costs.

[0062] In one embodiment, the multi-monitoring mode water accumulation monitor is miniaturized as a whole, and the outer shell 1 is protected by a metal shell. The length of the shell 1 is 166 mm, the width is 84.5 mm, and the thickness is 49.5 mm. The surface of the shell 1 is highly flat and can be adhered with structural adhesive. The side wall of the shell 1 is provided with a mounting hole for wall mounting, so that the water accumulation monitor can be installed against the wall or embedded in the curb or wall. The installation is simple and does not damage the road surface. In addition, since the overall volume of the shell 1 is small, the water accumulation monitor is both beautiful and does not affect traffic after installation.

[0063] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
