New Patent Introduction--A Water Meter System Based on Ultrasonic Measurement and GPRS Data Transmission
Today we introduced a national invention-granting patent - a water meter system based on ultrasonic measurement and GPRS data transmission. The patent was applied by Shandong Shuifalu Direct Drinking Water Co., Ltd. and was authorized to be announced on May 11, 2018.
Content DescriptionThe 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 inventionLarge-scale residential areas, factories, hotels, schools, hospitals and other large users of water consumption and the collection of water use in all regions, are using traditional meter reading methods, requiring a large number of manpower door-to-door meter reading, and have long plagued the water supply industry The problem of arrears in water charges directly brings huge economic costs to the water supply industry. In the prior art, meter readers need to find water meters one by one, manually read water meter readings, and manually record water meter readings. The current meter reading has low 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 results in the water supply and the water consumption being difficult to display according to the cumulative value of the water meter when the water meter's measurement result of the water flow rate is abnormal. Data dispute analysis of 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 purchasing water for a card, and solves the problems of water charges arrears that have long troubled the water supply industry, and thus will directly bring the water supply industry with With great economic benefits, the meter accuracy is high and the data transmission signal is stable; no mechanical transmission parts are not easily damaged, maintenance-free and have a long service life.
The drawing is a functional block diagram of the present invention.
To achieve the above objectives, 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 shell, and a display screen module all disposed in the shell, and an IC card reader. Card reader, GPRS module, CPU, storage, ultrasonic water meter and solenoid valve, water pipe and shell connection, display module, IC card reader, GPRS module, storage, solenoid valve and ultrasonic water meter are all electrically connected with CPU, GPRS The module is connected to the server data. The display module is a touch screen module. The solenoid valve and the ultrasonic water meter are all located 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 module all upload data to the server through GPRS module, swipe card as user authentication, latest user information storage memory. The water meter system based on ultrasonic measurement and GPRS data transmission includes the collector, pcb board and shell. The CPU and GPRS module are both electrically connected to the collector. For the public venue where the direct drinking water terminal is relatively concentrated: the ultrasonic water meter uploads data to the collection through the wired RS485 method. The device and the collector wirelessly upload data to the server through the GPRS module. The card is used as the authentication and the information is stored in the storage.
The display module, IC card reader, GPRS module, CPU and memory are all set on the pcb board. The pcb board is set in the housing. 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 request, the display module is usually in a sleep state, and it is displayed by awakening the IC card. The housing is provided with a display port for placing a display module. The housing is hinged with a protective cover covering the display port. The shell is a cubic chamber structure and the water pipes are round tubes.
In the present invention, a smart IC card is used to implement fee collection and water withdrawal method, and the card is used to take water and a card is swiped. The IC card reader reads the IC card information and transmits the information to the CPU. The CPU checks the information on the memory and the CPU controls the electromagnetic signal if the verification is correct. The valve opens the valve to take water, the second swipe card, and the CPU controls the solenoid valve to close the valve. Personal home use or exclusive use of terminals: the use of wired remote valve control (M-bus), bus power (site construction wiring required), ultrasonic water meters and collectors are wired, the collector wirelessly upload data to the server through the GPRS module. Ultrasonic measurement method is a non-contact measurement method. Its measurement accuracy is very high, almost no interference with the various parameters of the measured media; unique signal digital processing technology, so that the instrument measurement signal is more stable and anti-jamming Stronger ability and more accurate measurement. Non-mechanical transmission parts are not easily damaged, maintenance-free and long-life. The circuit is more optimized, has higher integration, lower power consumption and higher reliability. Intelligent standard signal output, man-machine interface friendly, a variety of secondary signal output. Pipe segment 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 the card, and simultaneously solving the problem of arrears in the water fee that has long troubled the water supply industry, it will directly bring huge economic benefits to the water supply industry, and the accuracy of the water meter measurement is high. The data transmission signal is stable; no mechanical transmission parts are not easily damaged, maintenance-free, and long life.
