Today I will introduce to you a national invention authorized patent-a water meter system based on ultrasonic measurement and GPRS data transmission. The patent was applied by Shandong Shuifa Lukong Direct Drinking Water Co., Ltd. and was authorized to be announced on May 11, 2018.
Description of contentThe invention belongs to the field of water meters, and in particular relates to a water meter system based on ultrasonic measurement and GPRS data transmission.
Background of the inventionThe large-scale residential areas, factories, hotels, schools, hospitals and other large users of water consumption and the total amount of water used in each area are collected by traditional meter reading methods. The problem of arrears of water charges directly brings huge economic costs to the water supply industry. In the prior art, the meter reader needs to find the water meters one by one when reading the meter, manually read the water meter readings, and manually record the water meter readings. The existing meter reading is low in convenience and consumes a lot of manpower. In addition, the existing water meter reading method can only obtain the current instantaneous flow value and the accumulated flow value of the water flow meter, which makes it difficult for the water supplier and the water party to display the accumulated value based on the water meter when the measurement result of the water meter is abnormal. Conduct data dispute analysis on water meters.
Summary of the inventionThe purpose of the present invention is to provide a water meter system based on ultrasonic measurement and GPRS data transmission, which saves a lot of manpower by buying water for cards, and at the same time solves the problem of arrears in water charges that have long plagued the water supply industry, so it will directly bring water supply Great economic benefits, high accuracy of water meter measurement, stable data transmission signal; no mechanical transmission parts are not easy to damage, maintenance-free, and long life.
The figure is a functional block diagram of the present invention.
In order to achieve the above purpose, the main technical solution of the present invention is to provide a water meter system based on ultrasonic measurement and GPRS data transmission, including an IC card, a server, a water pipe, a housing, a display module and an IC card reader all provided in the housing Card reader, GPRS module, CPU, storage, ultrasonic water meter and solenoid valve, the water pipe is connected to the housing, the display module, IC card reader, GPRS module, storage, solenoid valve and ultrasonic water meter are all electrically connected to the CPU, GPRS The module is connected to the server data, the display screen module is a touch screen module, and the solenoid valve and the ultrasonic water meter are all set on the water pipe.
After the IC card is recharged, the CPU automatically records and stores and updates the real-time data. Ultrasonic water meter, pre-charged IC card and display screen module all upload data to the server through the GPRS module, swipe the card as user authentication, and the latest user information is saved on the storage. The water meter system based on ultrasonic measurement and GPRS data transmission includes a collector, pcb board and housing. The CPU and GPRS module are electrically connected to the collector. For public places where direct drinking water terminals are concentrated: Ultrasonic water meters upload data to the collection through wired RS485 Device, the collector uploads data to the server wirelessly through the GPRS module, swipes the card as authentication, and the information is saved on the storage.
The display module, IC card reader, GPRS module, CPU and storage are all set on the pcb board, the pcb board is set in the shell, the information of the ultrasonic water meter is displayed on the display module, in addition, in order to meet the low power consumption as much as possible According to the requirements, the display module is usually in the sleep state, and it is displayed by the way of IC card wake-up. The housing is provided with a display port for placing the display module. The housing is hinged with a protective cover covering the display port. The outer shell is a cubic cavity structure, and the water pipe is a round pipe.
The invention adopts a smart IC card to implement payment and water withdrawal method, implements card purchase and water withdrawal, swipes the card once, the IC card reader reads the IC card information and transmits it to the CPU, and the CPU verifies the information on the storage device. The valve opens the valve to fetch water, the card is swiped twice, and the CPU controls the solenoid valve to close the valve and cut off the water. Personal household use or exclusive terminal: use wired remote valve control (M-bus), bus power supply (site wiring is required for construction), ultrasonic water meter and collector are wired, the collector wirelessly uploads data to the server through the GPRS module. Ultrasonic measurement method is a non-contact measurement method, its measurement accuracy is very high, and it is almost not interfered by various parameters of the measured medium; the unique signal digital processing technology makes the instrument measurement signal more stable and anti-interference The ability is stronger and the measurement is more accurate. No mechanical transmission parts are easy to damage, maintenance-free, and long life. The circuit is more optimized, the integration is higher, the power consumption is lower, and the reliability is higher. Intelligent standard signal output, friendly man-machine interface, multiple secondary signal output. Pipe section type small diameter measurement is economical and convenient, with high measurement accuracy.
The beneficial effects of the present invention are: on the basis of saving a lot of manpower by purchasing water for cards, and at the same time solving the problem of arrears in water fees that have long troubled the water supply industry, it will directly bring huge economic benefits to the water supply industry, and the accuracy of water meter measurement is high The data transmission signal is stable; no mechanical transmission parts are not easy to damage, maintenance-free, and long life.
