Description

An IoT water meter

technical field

The utility model belongs to the technical field of intelligent water meters, in particular to an Internet of Things water meter.

Background technique

At present, domestic smart water meters mainly include IC card water meters (including plug-in card type and radio frequency card type) and intelligent wireless remote transmission water meters. The water meter is read and collected and then the computer is used to settle the water bill. However, the above two methods have their own disadvantages: the water meter with IC card as the medium, after the user purchases the water, the water company does not know the usage of the user's water, and cannot monitor the usage of the water meter in real time; although the smart wireless remote water meter can be copied The data and operation status of water meters cannot solve the problem of pre-purchased water fees. Although the combination of IC card and remote meter will appear in the later stage, this type of water meter integrates the two modes, which increases the cost a lot, and Settlement and copying must be processed in real time, which brings a lot of workload to the operation of the water company. In addition, after the existing smart water meter runs out of water in the meter, the water meter will automatically close the valve to stop the water supply. In this way, if the water is cut off at night or on holidays, the user needs to pay for the water purchased at the designated business outlet. Inconvenience also adds a lot of workload to the water company. In addition, the existing smart water meters mainly solve the problem of payment, and cannot analyze the supply-sales ratio analysis of main pipeline water supply and user water consumption in real time, and cannot effectively analyze pipeline water leakage.

2. The utility model can manage the water meter valve completely based on the control of the management department. The switch valve operation is completed by the management department or computer settings, so that the valve can be used without closing the valve when the user does not recharge for special reasons. After the fee is paid, the amount of water paid in advance will be deducted to achieve a more humane management model.

3. The utility model realizes the timeliness of water fee payment, the user payment method is flexible, and the water fee payment can be made through the Internet or the bank at any time, and the payment information is automatically uploaded to the control center, and the control center computer controls the water meter according to the user's payment situation The opening of the valve does not require manual intervention, so that the user can pay at any time without going to the business outlet to pay.

4. The utility model sends the water meter data information to the control center in real time. The control center can realize the comprehensive management of water resources based on big data, realize the data analysis of the pipe network, large-diameter main water meters and branch household meters, and the computer management system It can calculate the difference between supply and sales at any time, and analyze the loss of the main pipeline and sub-pipes, and make up for the water loss caused by the pipeline running water in time, so as to realize the comprehensive management of water resources in the whole network.

detailed description

Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:

A kind of Internet of things water meter, as shown in Figure 1, comprises main control chip, mobile communication module, data memory, real-time clock, LCD liquid crystal display, button module, water meter data sampling module and water meter valve control module, main control chip and water meter valve control module respectively The mobile communication module, the data memory, the real-time clock, the LCD liquid crystal display, the water meter data sampling module and the water meter valve control module are connected together. In this embodiment, the main control chip adopts PIC16F1947 single-chip microcomputer to realize the central control function of the entire Internet of Things water meter, and the mobile communication module is composed of a GPRS/GSM communication module M26 and a SIM card connection, so that the data of the water meter is transmitted to the control center through the mobile communication network. Function, the data memory adopts 24C64 chip to store water meter data, the real-time clock adopts p8563 module to generate real-time time, the water meter data sampling module adopts Hall sensor circuit to realize the collection function of water data, and the water meter valve control module adopts motor drive L9110 for For the driving of water meter valves, the LCD liquid crystal display is used to display the water meter information, and the key module is used to manually start data communication and start the LCD liquid crystal display.

The working principle of the utility model is as follows:

(1) The control principle of the IoT water meter: the control circuit with the main control chip as the core is usually in a low-power working state, and only records the water volume information from the water meter. When the water volume information is recorded to the set sending data value, the water meter starts to move The communication module starts to transmit data, and uploads the water consumption information of the water meter and the working status of the water meter to the computer network. When the user does not use water for a long time, the mobile communication module is started to send data because there is no water volume information, so the water meter runs to the set time when the real-time clock runs. At this time, the water meter will automatically open the mobile communication module to upload the current water meter information to the computer network. When the water meter is connected to the computer, the computer receives the information of the water meter and sends the command to operate the water meter to the water meter to complete the control of the water meter.

(2) The valve control principle of the IoT water meter: The difference between the IoT water meter and the traditional water meter is that the control of the switch valve of the IoT water meter is completely controlled by the computer system, while the water meter only performs measurement and data transmission, and the water meter itself does not participate in the calculation. And data analysis, the process of data calculation and data analysis is completely completed by the computer, and the opening and closing of the water meter valve is also controlled by the command issued by the computer. The water meter itself does not control.

(3) The principle of water meter valve control: the opening and closing of the water meter valve is realized by computer commands. The switch valve drives the motor to work through the special valve control chip L9110, and detects whether the valve is opened or closed in place. If the valve is not opened or closed in place, the water meter LCD will display the valve failure.

(4) Working principle of the real-time clock: The real-time clock of the Internet of Things is mainly responsible for recording the generation time of the water meter and regularly starting the Internet terminal for data transmission. The time of the real-time clock is mainly checked by the mobile Internet base station to ensure the accuracy of the time In addition, the real-time clock is also responsible for starting the mobile communication module for data communication according to the timing information transmitted by the computer.

(5) Button control principle: Although the Internet of Things water meter works automatically, the water meter is powered by a battery and cannot always be turned on. The working mode is usually only for water measurement, and it relies on timing and quantitative start-up of the Internet of Things terminal. When the valve of the water meter needs to be opened immediately or the user needs to check the working status of the water meter, the user can immediately start the work of the water meter by manipulating the buttons, upload data and check the work of the water meter. The number of times the button is turned on per day is limited by the parameters transmitted from the computer.

It should be emphasized that the embodiments described in the utility model are illustrative rather than restrictive, so the utility model includes but not limited to the embodiments described in the specific implementation, and those skilled in the art according to the utility model Other implementations derived from the new technical solution also belong to the scope of protection of the utility model.
