Description

Technical Field

[0001] The utility model relates to the technical field of water supply equipment, and in particular to an Internet of Things water flow detection type residential management device. Background Art

[0002] With the improvement of people's living standards, there are more and more water use scenarios in daily life, and the water use points in houses are becoming more dispersed. They are no longer limited to bathrooms and kitchens. Various types of water use points will also appear in balconies, dining rooms, open kitchen islands and other areas. The increase in water use points has increased the risk of water leakage in houses. The product quality and installation quality of household water use equipment such as water purifiers, water softeners, and pipeline machines are difficult to control, and equipment leakage accidents occur frequently. Due to the impact of drainage pipe laying on lower-level residents, the impact of the location of drainage risers on interior decoration, and sanitation problems such as odor and insects in drainage pipes, it is difficult to configure floor drains at each water supply point. Therefore, leakage at the water supply point can easily cause the floor of the household to be soaked, causing damage to wooden floors, furniture, floor-standing appliances, etc. In severe cases, water will leak to the lower-level residents, causing more serious losses.

[0003] Existing water leakage alarms are mainly based on water immersion detectors, which consist of an alarm circuit that is open at the end of the detector. When water submerges the electrode probe, the conductivity of water is used to form a circuit closure, which sounds an alarm.

[0004] The water detector type water leakage alarm is more sensitive to water level detection alarms at fixed water storage points such as water tanks and pools, and can also be used with electric valves to control the on and off of water supply pipelines. However, in the bathrooms, kitchens, balconies, etc. of residences and apartments, where the water usage status is uncertain and there is water on the ground under normal circumstances, it is easy to have false alarms and missed alarms. In addition, the water detector type water leakage alarm requires a water probe to be installed in each water supply terminal area, and the location of the probe directly affects the alarm effect. When the whole house is arranged, the cables are too long and the terminal detectors are complicated to arrange, making it difficult to play a practical role in the residence.

[0005] Therefore, this application designs an Internet of Things water flow detection type residential management device and its use method. Combined with the water usage characteristics of residences and apartments, reliable anti-leakage equipment is made using simple and easily available electronic components, and water leakage alarm information is sent using the Internet of Things system. False alarms and missed alarms can be effectively avoided, and water supply can be quickly cut off when a leak occurs. It can be widely used in residential water supply systems.

[0027] Figure 1-Figure 3 This is a specific embodiment of the utility model, which is an Internet of Things water flow detection type residential management device.

[0028] Usually, water use in residences and apartments is intermittent, and the continuous water flow time for drinking, washing, bathing, and washing clothes is short, and there is a strong water use pattern. For example, dual-income families have active water use behavior from 6:00 to 8:00 in the morning, and almost no water use behavior from 9:00 to 11:00; elderly families also have certain water use patterns, and it is possible to judge whether the elderly at home have physical abnormalities based on the water use patterns. This embodiment uses this feature and adopts the method of adding a water flow detector to the water supply pipe to obtain water use information such as the continuous water flow duration value and the continuous static duration, and compares it with the set value to determine whether the water use status is normal. When the set water flow duration or static duration is exceeded, it is judged as abnormal water use, and an alarm notification is issued through the Internet of Things module to remind residential users or managers to check the indoor status. When a reply is received or no reply is received after the timeout, the water supply pipeline is cut off to avoid losses caused by leakage.

[0029] The water flow indicator 2 of this embodiment is arranged in the water supply pipeline 1, and a water flow monitoring data analysis unit 3 is provided on the water flow indicator 2. The water flow monitoring and analysis unit 3 is communicatively connected to the Internet of Things server 6. The Internet of Things server 6 is also communicatively connected to the valve action control unit 4. The valve action control unit 4 is connected to the normally open solenoid valve 5 arranged on one side of the water flow indicator 2.

[0030] The water flow indicator 2 is used to detect the water flow state and send an on-off signal to the water flow monitoring data analysis unit 3. The water flow monitoring data analysis unit 3 is fixedly connected to the water flow indicator 2. The water flow monitoring data analysis unit 3 and the water flow indicator 2 are connected by a signal line, which is used to receive the signal of the water flow indicator 2, measure the water flow on-off time, and compare it with the set value. The Internet of Things server 6 is set nearby, which is used to receive the signal sent by the water flow monitoring data analysis unit 3, and send a preset alarm information through the communication alarm unit 7, and at the same time receive the instruction sent by the user-side control terminal, and send an action signal according to the instruction. The user-side control terminal can also obtain the current state of the water supply system through the Internet of Things server 6. The normally open solenoid valve 5 is installed at the downstream position of the water flow indicator 2 on the water supply pipeline 1, which is responsible for cutting off the water supply; the water flow indicator 2 is installed on the normally open solenoid valve 5, which is used to receive the signal of the Internet of Things server 6 and control the opening and closing of the normally open solenoid valve 5.

[0031] The specific operation mode of this embodiment is as follows:

[0032] S1, setting detection and management logic that conforms to the user's living habits on the IoT control terminal, including water flow duration thresholds for each period on weekdays, water flow duration thresholds for each period on statutory holidays, and water flow stillness duration thresholds;

[0033] S2, the water flow indicator 2 detects the water flow state, converts the flow and static state of the water in the pipeline into electrical signals and transmits them to the water flow monitoring data analysis unit 3, which records the start and end time of the water flow and static state and sends them to the Internet of Things server 6 for analysis;

[0034] S3, the IoT server 6 analyzes the duration of the water flow state according to the current time period, and sends a corresponding signal to the IoT control terminal or the valve action control unit 4 according to the situation. When the water flow time or static time exceeds the threshold value within the corresponding time period, an alarm signal is sent to the IoT control terminal; when the IoT control terminal is received,

[0035] If the terminal command or the IoT control terminal feedback is not received for a predetermined time, the IoT server 6 executes the operation procedure and sends a valve closing signal to the valve action control unit 4;

[0036] S4, the valve action control unit 4 controls the normally open solenoid valve 5 to execute a closing or opening action according to the signal transmitted by the Internet of Things server 6, and feeds back the working status of the solenoid valve to the Internet of Things server 6.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
