Abstract

The utility model discloses a reforming device for causing a domestic water meter to have remote reading function, which comprises a '*0.01' output shaft of an original water meter, a CPU and a displayer. The utility model is structurally characterized in that the '*0.01' output shaft of the original water meter is engaged and connected with a drive gear which is engaged and connected with an output shaft, wherein the number of gear teeth of the drive gear is the same with the number of gear teeth of the original water meter form '*0.01' water quantity to '*1' water quantity. The output shaft is provided with a double-layer gear. The upper and the lower layers of the gear are respectively distributed with ten convex tops, and the convex tops on the upper layer cross the convex tops on the lower layer at 18 DEG. The convex tops on each layer respectively correspond a light touch switch, can contact contacts of the light touch switch, and deliver a pulse to the CPU through a conducting wire, and after the pulse is treated by the CPU, water consumption of a user's water meter is displayed by the displayer. The utility model has the advantages that a trouble that people can knock and enter a door for reading meters from house to house is reduced; user's water using situation can be monitored in real time; meter reading concentration is realized; the project improvement is convenient; the investment is less.

Description

Domestic meter transform the device of remote meter reading as

Affiliated technical field:

The utility model relates to the device that a kind of domestic meter transform remote meter reading as.

Background technology:

Owing to be becoming tight water resource day, control water and scientific management water resource have become the important topic that national governments consider.The IC-card prepay water meter and the remote meter reading of Tui Hanging all is to the good scientific management means of water resource in the market.But are there there some very real situations at present, what if for original water meter that has been equipped with? this is a very big numeral, transform, and engineering is too big, invest also very greatly, is not easy enforcement.Thereby a kind of small investment proposed original old water meter is transformed into a task of the present utility model.

Summary of the invention:

The purpose of this utility model is to provide a kind of compact conformation, domestic meter easy for installation to transform the device of remote meter reading as.The purpose of this utility model is to realize like this, described domestic meter transform the device of remote meter reading as, " * 0.01 " output shaft that comprises original water gauge, CPU and display, its design feature is original water gauge " * 0.01 " the output shaft transmission gear that is connected with a joggle, the transmission gear output shaft that is connected with a joggle, the gear number of teeth of transmission gear is the same with the gear number of teeth of original water gauge from " * 0.01 " water yield to " * 1 " water yield, a double-layer gear is housed on output shaft, double-layer gear two-layer up and down all is distributed with 10 protruding tops, two-layer up and down protruding top is staggered with 18 ° of angles, every layer of all corresponding touch-switch in protruding top, every layer of protruding top can contact with the contact of touch-switch and export a pulse by lead and give CPU, handles and pass through the water consumption of display explicit user table through CPU.The purpose of this utility model also can be achieved through the following technical solutions, and described domestic meter transform the device of remote meter reading as, and its characteristics are 10 protruding tops of up and down two-layer all five equilibriums distribution of double-layer gear.The utlity model has following characteristics, present situation and actual needs according to domestic estate management,, easy construction reliable, take into account the principle of design of cost performance in line with mass of system, adopt collecting and distributing mode, step control, the centralized management method of operation to design and develop and a kind ofly can be installed in indoor water meter, realize that outdoor teletransmission checks meter original.Its advantage be reduce loaded down with trivial details knock at the door from house to house to enter the room check meter, and can timing monitoring user water situation, realize centralized automatic meter-reading, and improvement project is convenient, small investment; But cpu peripheral (12C bus interface), by software setting regularly or the power-off time of the current water consumption of each water meter of real-time storage, total water amount, each water meter, loss of data during with anti-power failure is called wherein data and demonstration with the software control mode; Adopt real-time timepiece chip (12C bus interface) to realize time measurement, this installs configurable four function keys, is used for query display respectively respectively to show the power-off time of current water consumption, total water amount, each water meter, and carries out water meter and time initial value setting.Can realize automatic data logging, estate management control center computing machine is by RS-485 converter and the field management unit communication that is positioned at far-end, and remote auto is copied and accepted subscriber's meter meter reading and system status information.The design of employing collecting and distributing type, good reliability even a certain user or a water meter are unusual, can not influence other user and bus yet.Self-contained battery, the operate as normal of system when guaranteeing to have a power failure, data are not lost.Adopt RS-485 special line system communication quick, real-time makes system copy and accept rate and the tangible raising of reliability well, can satisfy fully and check meter and monitoring function.The utility model also has characteristics such as simple in structure, easy to install.
