[0043] ​The pressure sensing module 30 has its detection end sealed on the corresponding hole 102 of the housing 101. The pressure sensing module 30 is used to contact the water body that reaches the second preset water level and generate corresponding water level data by pressure sensing. The second preset water level is greater than the first preset water level.

[0044] The wireless communication module 40 is connected to the power module 10 and is disposed inside the housing 101, and is used to communicate wirelessly with external communication devices.

[0045] The processor 50 is connected to the capacitance detection module 20, the pressure sensing module 30 and the wireless communication module 40 respectively and is disposed inside the housing 101. The processor 50 is used to acquire water level data triggered by the capacitance detection signal, and to send the water level data corresponding to the capacitance detection signal and the water level data of the pressure sensing module 30 to the external terminal device through the wireless communication module 40.

[0050] The road water accumulation monitoring device does not need to be provided with a vertical rod and an outdoor box, and has simple installation mode and low cost.

[0051] The power module 10 can adopt a battery and a corresponding charging module, in an optional embodiment, as shown in Figure 3 The power module 10 can adopt a battery and a corresponding charging module, in an optional embodiment, as shown in

[0052] The power module 10 can adopt a battery and a corresponding charging module, in an optional embodiment, as shown in

[0053] The wireless charging module 11 is connected with the rechargeable battery 12, and is used for wirelessly connecting with an external wireless device and charging the rechargeable battery 12.

[0054] The power management module 13 is connected with the rechargeable battery 12, and is used for managing the output power of the rechargeable battery 12 and outputting working power of corresponding size to each module in the road water accumulation monitoring device.

[0055] In the embodiment, the rechargeable battery 12 is wirelessly charged by the wireless charging module 11 and the external wireless device through the shell 101, therefore, the corresponding charging interface does not need to be arranged on the shell 101, the sealing property of the road water accumulation monitoring device is improved, and the power management module 13 is the output end of the power module 10, is used for managing the power of the rechargeable battery 12 and providing corresponding working power for each module.

[0056] The wireless charging module 11 can adopt a corresponding induction coil and a power conversion circuit. The induction coil can be attached in the shell 101 and perform magnetic induction with external wireless devices through the shell 101. The induction coil performs magnetic-electric conversion, and the power conversion circuit converts and outputs a corresponding charging power to the rechargeable battery 12.

[0057] The power management module 13 can adopt a corresponding power management chip. The power management chip can be connected with the processor 50 and switch output of working power to each module according to a switch control signal output by the processor 50, so as to realize low-power consumption control of the road water accumulation monitoring device.

[0058] In order to reduce the power consumption of the road water accumulation monitoring device, in an optional embodiment, the processor 50 is further configured to:

[0059] When initially powered on, the working condition information of each module of the road water accumulation monitoring device is reported through the wireless communication module 40, and when each module works normally, the low-power consumption sleep mode is entered, and the power module 10 is controlled to cut off the working power of the wireless communication module 40 and the pressure sensing module 30;

[0060] In the low-power consumption sleep mode and when no capacitance detection signal is received, switching is performed between the low-power consumption sleep mode and the working mode according to a preset time interval, and in the working mode, the power module 10 is controlled to provide working power for the wireless communication module 40 and the pressure sensing module 30, and water level data of the capacitance detection module 20 and the pressure sensing module 30 are acquired and uploaded.

[0061] When the capacitance detection signal is received in the low-power consumption sleep mode, the working mode is switched to, and in the working mode, the power module 10 is controlled to provide working power for the wireless communication module 40 and the pressure sensing module 30, and water level data of the capacitance detection module 20 and the pressure sensing module 30 are acquired and uploaded.

[0062] In the embodiment, the processor 50 is connected with the power management module 13 and outputs a corresponding switch control signal to the power management module 13. The power management module 13 selects output of working power to each module according to the received switch control signal.

[0063] In specific work, when the road water accumulation monitoring device is put into work and each module is connected normally, the processor 50, the capacitance detection module 20, the pressure sensing module 30, and the wireless communication module 40 are powered on. The processor 50 acquires working condition information of each module to determine whether each module works normally. When one of the modules is abnormal, the processor 50 sends abnormal information to an external terminal device through the wireless communication module 40 and controls the power management module 13 to stop power supply to each module, so that the road water accumulation monitoring device is offline and stops working.

[0064] Likewise, when the wireless communication module 40 is abnormal or the external terminal device receives abnormal information, the external terminal device can display or issue corresponding indication information, so that the maintenance personnel can maintain the device.

[0065] Meanwhile, when each module is working normally, the processor 50 outputs a switch control signal to the power management module 13 to cut off the working power supply of the pressure sensing module 30 and the wireless communication module 40, maintain the working power supply of the capacitance detection module 20, and switch to a low-power sleep mode by itself. In this state, only the capacitance detection module 20 maintains a working state.

[0066] When the water level does not rise to the first preset water level, the capacitance detection module 20 does not output a capacitance detection signal. At this time, it is activated from the low-power sleep mode to the working mode every preset time interval, and controls the power management module 13 to provide working power supply for the pressure sensing module 30 and the wireless communication module 40. The pressure sensing module 30 detects and obtains corresponding water level data, and sends the water level data detected by the capacitance detection module 20 and the pressure sensing module 30 to the external terminal device through the wireless communication module 40, and then enters the low-power sleep mode again after the sending is completed, and controls to cut off the working power supply of the pressure sensing module 30 and the wireless communication module 40. On the one hand, it realizes data acquisition at an interval, and on the other hand, it can determine whether the capacitance detection module 20 is in a normal working state during the working period. The length of the preset time interval can be set according to requirements, for example, 2 hours, 4 hours, etc.

[0067] Meanwhile, when the water level rises to the first preset water level, the capacitance detection module 20 outputs a capacitance detection signal. At this time, the processor 50 is activated from the low-power sleep mode to the working mode, and the processor 50 controls the power management module 13 to provide working power supply for the pressure sensing module 30 and the wireless communication module 40. The pressure sensing module 30 detects and obtains corresponding water level data, and sends the water level data detected by the capacitance detection module 20 and the pressure sensing module 30 to the external terminal device through the wireless communication module 40, and then enters the low-power sleep mode again after the sending is completed, and controls to cut off the working power supply of the pressure sensing module 30 and the wireless communication module 40.

[0068] The capacitance detection module 20 can adopt corresponding couplers, gaskets and the like, as shown in Figure 3 In an optional embodiment, the capacitance detection module 20 includes:

[0069] The metal gasket 21 is coupled with the water body outside the shell 101 to a first preset water level to generate a capacitance signal with a corresponding capacitance value;

[0070] The comparison circuit 22 is connected with the metal pad 21 and the power module 10, and is used for comparing the capacitance signal with a preset capacitance value and outputting a capacitance detection signal corresponding to the size.

[0071] In the specific work, the metal pad 21 is arranged at a relatively low position in the shell 101, and the arrangement position corresponds to the first preset water level. When the water level rises to the first preset water level, the metal pad 21 is coupled with the water body through the shell 101 and generates a capacitance signal corresponding to the capacitance value. When the water level does not reach the first preset water level, the metal pad 21 outputs a capacitance signal of another capacitance value. The comparison circuit 22 is provided with a preset capacitance value, and compares the capacitance signal output by the metal pad 21, so as to determine whether the water level reaches the preset water level and whether the interrupt detection is triggered.

[0072] In an optional embodiment, when the water level does not reach the first preset water level, the metal pad 21 outputs a small capacitance, and when the water level reaches the first preset water level, the metal pad 21 is coupled to output a large capacitance. The preset capacitance value is greater than the capacitance value of the small capacitance and less than the capacitance value of the large capacitance. When the comparison circuit 22 compares the capacitances, a high or low level signal corresponding to the size is output. The processor 50 can determine whether the current water level reaches the first preset water level according to the high or low level signal.

[0073] The comparison circuit 22 can be composed of a comparator and other peripheral auxiliary components.

[0074] The metal pad 21 can be a corresponding metal sheet, pad, etc. In an optional embodiment, the metal pad 21 is a metal pad, and the metal pad and the comparison circuit 22 are arranged on a circuit board, and the metal pad is formed by welding.

[0075] In order to further reduce power consumption, in an optional embodiment, the processor 50 is further used for:

[0076] When the metal pad 21 does not output a capacitance signal corresponding to the size, the comparison circuit 22 is triggered to enter a low-power standby state;

[0077] When the metal pad 21 outputs a capacitance signal corresponding to the size, the comparison circuit 22 is triggered to enter a working state.

[0078] In the embodiment, the capacitance signal output by the metal pad 21 is an interrupt detection signal, and the metal pad is further connected with the processor 50. When the metal pad 21 outputs a capacitance signal of a small capacitance value, it indicates that the current water level is low. At this time, the processor 50 triggers the comparison circuit 22 to enter a low-power standby state, and the processor 50 does not output a high or low level capacitance detection signal. At this time, the working current of the comparison circuit 22 is uA level.

[0079] And, when the metal pad 21 outputs a large capacitance value of the capacitance signal, it indicates that the current water level reaches the first preset water level, at this time, the processor 50 triggers the control comparison circuit 22 to enter the working state, and converts the output corresponding to the high and low level of the capacitance detection signal, at this time, the working current of the comparison circuit 22 reaches mA level.

[0080] By the capacitance value of the capacitance signal output by the metal pad 21, the corresponding working state of the comparison circuit 22 can be adjusted, and the power consumption of the road water monitoring device is further reduced.

[0081] The pressure sensing module 30 can adopt a corresponding pressure sensor, in an optional embodiment, the pressure sensing module 30 includes a pressure sensor, a pressure sensor includes a plurality of pressure sensitive elements at different preset water levels, each pressure sensitive element is sealingly arranged on the corresponding hole position 102 of the shell 101;

[0082] Alternatively, the pressure sensing module 30 includes a plurality of pressure sensors, and the plurality of pressure sensors are located at different preset water levels, and the pressure sensitive elements of each pressure sensor are sealingly arranged on the corresponding hole position 102 of the shell 101.

[0083] The pressure sensor includes a pressure sensitive element and a signal processor 50, the pressure sensitive element is arranged on the corresponding hole position 102 of the shell 101, the hole position 102 is sealingly arranged, the pressure sensing module 30 can be provided with one or more pressure sensors, when one pressure sensor is used, the pressure sensor can be provided with a plurality of pressure sensitive devices, and arranged in the corresponding hole position 102 according to the high and low water level, when a plurality of pressure sensors are used, each pressure sensor can be provided with one or more pressure sensitive devices, and the pressure sensitive devices of the plurality of pressure sensors are arranged in the corresponding hole position 102 according to the high and low water level, so as to realize the water level monitoring of the road water.

[0084] Among them, in order to further reduce the power consumption, the frequency of data reporting can also be reported according to the water level data monitored by the pressure sensor, that is, in an optional embodiment, the processor 50 is also used for:

[0085] According to the different water level data of the pressure sensing module 30, the different information acquisition time interval and information reporting time interval are adjusted, and the size of the information reporting time interval changes with the water level.

[0086] Among them, the plurality of pressure sensitive devices correspond to a plurality of preset water levels, when the water level reaches the pressure sensitive device of different height, the pressure sensor outputs different water level data, wherein the higher the water level represented by the water level data, the higher the data acquisition and reporting frequency, and the lower the water level guaranteed by the water level data, the lower the data acquisition and reporting frequency.

[0087] For example, the second preset water level range of the pressure sensing module 30 includes three water levels, including a first water level F1, a second water level F2, and a third water level F3, the first water level F1 is higher than the second water level F2, and the second water level F2 is higher than the third water level F3, when the water level value collected by the pressure sensor is greater than the first water level F1, the water level data collection time interval is set to 1 minute, and the reporting time interval is 1 minute, when the water level value collected by the pressure sensor is greater than the second water level F2 and less than the first water level F1, the water level data collection time interval is set to 2 minutes, and the reporting time interval is 2 minutes, when the water level value collected by the pressure sensor is greater than the third water level F3 and less than the second water level F2, the water level data collection time interval is set to 5 minutes, and the reporting time interval is 5 minutes, and when the water level value collected by the pressure sensor is less than the third water level F3, the water level data collection time interval is set to 10 minutes, and the reporting time interval is 10 minutes, by adjusting the water level data collection and reporting time, the power consumption of the road water accumulation monitoring device is further reduced.
