Among them, the wireless communication module of the water accumulation monitoring device includes a first wireless communication antenna 107, and the wireless communication module of the water accumulation monitoring and alarm terminal includes a second wireless communication antenna 201; the water accumulation monitoring device is provided with multiple sensors, and the data of the sensors is collected through the data acquisition module. The water accumulation monitoring and alarm terminal includes a data processing module and an alarm module connected to the data processing module. The water accumulation monitoring and alarm terminal is used to receive water accumulation and water leakage data, data processing and buzzer alarm. The water accumulation monitoring device is used to monitor on-site water leakage and water accumulation and collect water accumulation data, and transmit the collected data to the water accumulation monitoring and alarm terminal in real time through the 433MHz wireless communication network and LoRa wireless communication technology; the water accumulation monitoring and alarm terminal will sound a buzzer alarm after receiving the water accumulation data, prompting the staff to carry out emergency disposal work, thereby realizing remote monitoring and alarm of water accumulation and water leakage.

[0025] Specifically, Figures 2 to 6As shown, the water accumulation monitoring device 1 includes a box body 101, the interior of the box body 101 is divided into an upper space and a lower space by a partition 102, a water leakage rope 103 and a water depth sensor 104 are arranged in the lower space, and a water immersion sensor 105 and a main control unit 106 are arranged in the upper space, the water immersion sensor 105 is respectively connected to the water leakage rope 103 and the main control unit 106 for communication, and the main control unit 106 is connected to the water depth sensor 104 for communication. The water accumulation monitoring device 1 also includes a temperature and humidity sensor 114 connected to the main control unit 106, and the temperature and humidity sensor 114 is used to collect temperature and humidity data of the water accumulation monitoring area.

[0026] The box 101 is provided with a first wireless communication antenna 107, a switch 108 and a DC socket 109, and a battery 110 is provided in the upper space. The first wireless communication antenna 107, the battery 110, the switch 108 and the DC socket 109 are all connected to the main control unit 106, and the switch 108 is used to realize the on and off of the overall power supply of the water accumulation monitoring device. Specifically, Figure 4 and Figure 5 As shown, the main control unit 106 is connected to the power supply (battery 110 and DC socket 109) through the relay 115, and the water sensor 105 is electrically connected to the relay 115 and can control the working state of the relay 115. Specifically, when the water sensor 105 detects water accumulation through the leaking rope 103, the water sensor 105 controls the normally open contact of the relay 115 to close, and the main control unit 106 is powered on. The main control unit 106 controls the water depth sensor 104 to turn on and transmits data to the water accumulation monitoring alarm terminal. Due to the setting of the DC socket 109 and the battery 110, the water accumulation monitoring device can be compatible with both direct current and battery power supply, and has a charging function; it adopts an ultra-low power consumption design, and is in an ultra-low power consumption operation state when there is no water accumulation, and the battery life can reach 3 months on a single charge.

[0027] In this embodiment, the relay 115 is integrated into the water sensor 105 . In other embodiments, the relay 115 may also be a separately provided component.

[0028] Two waterproof cable heads 111 are provided on the partition 102 , one of which is connected to the water leakage rope 103 and the water immersion sensor 105 , and the other is connected to the water depth sensor 104 and the main control unit 106 .

[0029] The lower part of the box body 101 is provided with a plurality of through holes 113 communicating with the lower space, so as to facilitate the accumulation of water to enter the lower part of the box body 101 and prevent the accumulation monitoring device from tipping over in the accumulation of water with a large flow rate.

[0030] A protective tube 112 is provided in the lower space of the box body 101 , the lower end of the protective tube 112 is arranged through the bottom of the box body 101 , the leakage rope 103 and the water depth sensor 104 are both located in the protective tube 112 , and a through hole is also opened in the lower part of the protective tube 112 .

When there is no water accumulation, only the water immersion sensor works, and the data acquisition, wireless transmission and other modules are in a power-off state, and the power consumption is less than 0.1W; when water accumulation occurs, the data acquisition module is awakened, and the water leakage and water accumulation depth data are transmitted to the water accumulation monitoring alarm terminal through LoRa wireless communication technology. The water accumulation monitoring alarm terminal will sound an alarm after receiving the water accumulation data.

[0033] The working steps of the water accumulation monitoring and alarm system are as follows:

[0034] When the machine is turned on without water accumulation, only the water immersion sensor 105 is powered on to start monitoring the water accumulation state;

[0035] After the water immersion sensor 105 detects the accumulated water, the water immersion sensor 105 controls the normally open contact of the relay 115 to close, the main control unit 106 is powered on, and the main control unit 106 controls the water depth sensor 104 to turn on, and the water depth sensor 104 collects the accumulated water depth;

[0036] The main control unit 106 collects the water depth H at the initial set time interval t and calculates the water level rising speed V = (H 2t -H t ) / t;

[0037] The urgency of the current data transmission is determined by the depth of water accumulation and the speed of water level rise R=w1*V+w2*H, where W1 and W2 are weights; the urgency R is compared with the preset value to determine whether the main control unit 106 and the first wireless communication antenna 107 are in sleep mode, as well as the sleep time interval T1 and the wireless data transmission time interval T2; if the main control unit 106 enters sleep mode, the main control unit 106 is awakened by RTC to achieve the purpose of saving energy consumption;

[0038] The data is sent to the water accumulation monitoring alarm terminal 2 via the first wireless communication antenna 107 .

[0039] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
