Description

Alarm Realization Method of Household Water Leakage Monitoring and Alarm System

technical field

The invention relates to the field of monitoring and alarming, in particular to an alarming realization method of a household water leakage monitoring and alarming system for monitoring household water leakage.

technical background

In real life, water leakage often occurs due to aging, leakage, rupture of water pipes, taps not closed or forgotten to close, etc., which not only causes waste of water resources and increases in water bills, but also endangers buildings and causes damage to houses and property losses, especially in In a densely populated residential area, a water leak may cause damage to many adjacent and lower units, bringing inconvenience to the daily life of residents. Such situations are not uncommon in real life, so it is particularly important to monitor the household water use situation and promptly notify the owner of the water leakage situation at home so that it can be dealt with in a timely and effective manner. Water leakage includes water leakage in a narrow sense and abnormal water use. Water leakage in a narrow sense refers to running, popping, dripping, and leaking; abnormal water consumption refers to water with a relatively constant flow rate for a long time, such as forgetting to turn off the faucet, taking a bath without adjusting the water flow for a long time, and malfunctioning of the washing machine when it is working.

There are currently several methods for detecting water leakage, such as using ultrasonic waves, acoustic vibration signals of water flow, or using special detection wires for detection. The above method is mainly used to find the leak point after the water leak occurs, so as to find the cause of the leak. It has no function of preventing the leak, and there are defects such as complicated equipment, expensive price, and inconvenient installation. At the same time, the existing water leakage alarm systems on the market are suitable for water leakage detection in the industrial field, but there are almost no water leakage alarm systems for ordinary households.

Contents of the invention

Aiming at the current problems, the present invention proposes an alarm realization method of a household water leakage monitoring and alarm system that monitors, alarms and handles household water leakage, realizes the prevention and control of household water leakage, and achieves the purpose of water conservation and safe water use.

The system includes pulse water meter, solenoid valve, main controller, automatic dialer and alarm monitor. The pulse water meter and the solenoid valve are connected on the water inlet pipeline, the pulse output end of the pulse water meter is connected with the counting port of the main controller, and the output interface of the main controller is connected with the solenoid valve. The master controller is connected with the home telephone line through an automatic dialer. The alarm monitor is connected with the main controller through a signal line. The alarm monitor is provided with an alarm buzzer, a water leakage alarm indicator light, a power shortage indicator light and an alarm release button. The water meter and the electromagnetic valve can also adopt the integral type of valve and meter.

The system's alarm realization method is that the main controller receives and analyzes the pulse signal from the pulse water meter, and compares it with the historical data to judge the change rate of water use. If the rate of change of the pulse is greater than the set value of the rate of change, the system will not operate; if the rate of change of the pulse is less than the set value of the rate of change, and the duration reaches the set value of the alarm time, the alarm monitor will be activated, and the sound and light will alarm to remind the owner. If no one removes the alarm within the set reminder removal time, the automatic dialer is started, the owner is dialed, and the owner is notified to deal with it. If the main controller does not receive the owner's call-back message within the set confirmation release time, the solenoid valve is started to shut off the water inlet pipeline.

The present invention judges whether the water use is normal by analyzing the change rate of the water use, and can judge the current water use situation in time. When a water leak occurs, the system will automatically transmit the leak information to the owner through the automatic dialing machine, so as to deal with it timely and effectively. The pulse water meter, electromagnetic valve, automatic dialer and the like in the present invention can be purchased on the market, and only the pulse water meter can be used to judge whether there is water leakage, which is low in cost, convenient to use, safe and reliable.

Fig. 2 is the working flowchart of the main controller in the present invention.

Detailed ways

As shown in FIG. 1 , the household water leakage monitoring and alarm system includes a pulse water meter 10 , a solenoid valve 11 , a main controller 12 , an automatic dialer 2 and an alarm monitor 5 . Household water point 8, pulse water meter 10 and electromagnetic valve 11 are all connected on the water inlet pipeline 9. The pulse output end of pulse water meter 10 is connected with the counting port of main controller 12, and the output port of main controller 12 is connected with solenoid valve 11; Main controller 12 is connected with family telephone line 1 signal by automatic dialer 2; Alarm monitor 5 is connected with the main controller 12 through a signal line. Alarm monitor 5 is provided with alarm buzzer 3, water leakage alarm indicator light 4, insufficient power indicator light 6 and release alarm button 7.

As shown in Figure 2, the workflow of the home water leakage monitoring and alarm system is to set the pulse rate of change according to the parameters of the pulse water meter. The main controller receives and analyzes the pulse number from the pulse water meter, compares it with the historical data, and judges the change rate of water consumption. If the pulse change rate is greater than the set pulse change rate, it means that the water consumption is within the normal range at this time, and the system does not operate; In case of water leakage or artificially abnormal water use, start the alarm monitor at this time, sound and light alarm, and remind the owner. If no one lifts the alarm within five minutes, then start the automatic dialer, dial the owner's phone, and notify the owner to deal with it. If the main controller does not receive the owner's call-back message within five minutes, the solenoid valve will be activated to shut off the water inlet pipeline. The alarm time in this method is set by the user according to his own water habits (adjustable from 0 to 2 hours).

The components and their main functions are as follows:

1. Pulse water meter: It is used to detect the water flow of the water inlet main pipe and provide relevant information of water consumption to the main controller.

2. Solenoid valve: open or close the water inlet pipeline.

3. Main controller: This part is composed of a single-chip microcomputer system, which receives the pulse signal from the pulse water meter, analyzes and judges the water consumption situation, sends corresponding control signals to the alarm and automatic dialer, and performs the call-back signal from the owner. deal with.

4. Automatic dialer: This part is mainly used to realize the function of automatically dialing the owner's mobile phone when the owner needs to be notified, and can receive and recognize the control signal sent back by the owner, and send the signal to the main controller.

5. Alarm monitor: When it is judged that there is water leakage, abnormal water use or insufficient power of the system power supply, it will send out a corresponding alarm signal, start this link, and remind the owner to deal with it.
