Description

Indirect Remote-controlled Automatic Metering System

The present invention relates to an automatic remote meter reading system, which converts a decimal analogue weighing into a binary digital weighing so that a computer can recognize it. To automatic remote meter reading.

Until now, people have read meters such as electricity, water gas, etc., and the meter readers visit each family. The need for meter reading is required.

However, only a few years ago, the communication environment, which is a means of transmitting remotely read signals, has not been developed as it is, and the designed remote metering systems have not been put to practical use, and digital meters such as water, electricity, and gas are converted into digital methods. There are many technical, institutional, economic, and technical problems that have not been put to practical use.

In order to realize the automatic remote meter reading system of the present invention, first, the decimal analogue weighing of the meter must be converted into the binary digital weighing correctly. Next, the display window (LCD, etc.) same as the existing analogue weighing is installed and the customer directly compares it. It is important to be able to see and be reliable. Next, adopt MICRO COMPUTER and combine it with LAN, INTERNET, etc. to supply water, electricity, gas, etc. It should be possible to make data by inputting the information to the computer system of GAS Corporation by providing the read information to the computer.

To do so, it is necessary to recognize the stability and reliability by diagnosing abnormality of the system such as stable power supply and fault diagnosis function. Especially, it can be installed at low cost without replacing or modifying the meter of existing facility, and it is easy to maintain Both economics and safety must be recognized.

The present invention for achieving the technical problem as described above is a sensing chip 302 that detects by converting the digital signal on the upper instrument panel 301 of the existing meter (Fig. 3) while still using the existing analog display of the decimal type digital meter. It is a semiconductor device designed to perform remote automatic meter reading task based on its own MICRO COMPUTER and HOST COMPUTER commands of suppliers connected to LAN and INTERNET after detecting and measuring the variation of coefficient by attaching.

The function of each circuit of FIG. 1 is explained in full detail.

The sensing chip 101 is placed on the top of the two unit numbers of '1.1' or 'day' which is the lowest unit among the five units of the meter ('0.1', 'day', 'ten', 'white', 'cloth'). If required, install it in two units.) Install a photo sensor and convert the contrast of the number plate into an electrical signal to detect the signal.

The basic principle of sensing: 10 numbers from 1 to 0 are rotated sequentially in the ROTARY method. When the reflective photo sensor is installed in the center of the number, the sensor rotates. The same result is obtained by repeatedly scanning 10 numbers from 1 " to " 0 ".

In this way, scanning the centers of numbers (1 is a combination of black and white) from "1" to "0" sequentially creates scan lines with certain characteristics (long and short intervals) for each number. The number of "0", "1" to "9" is repeatedly scanned, and this signal is inputted to a computer, and when it is repeated and compared, the movement of one number is read.

At this time, when one number detects the moment passing through the scanning point of PHOTO SENSOR, it is read by MICRO COMPUTER to make one pulse, and this pulse is operated by step by step of LCD counter.

However, if you set the same as the analog weighing value when you install PHOTO SENSOR for the first time, it will be the same LCD instrument window.

The DIGITAL signal generator 102 sends the electrical signal sent from the sensing chip to the MICRO COMPUTER and compares the sequential change of ten digits from 1 to 0 to read the progress of the numerical value so that one number passes. Each time a binary digital pulse is generated.

The DIGITAL measurement circuit 103 has a built-in LCD counting device in the same unit as the meter. When the DIGITAL PULSE is received, the DIGITAL measuring circuit 103 operates in the STEP BY STEP method according to the number of pulses. Done.

In this digital measuring circuit, a button is installed so that the count value can be corrected and set to the same value as the meter.

Also, in order to save power, SW is installed so that LCD panel is turned off at normal times.

The ID number 104 is a function of assigning a customer address so that every computer recognizes its own address in a LAN or an INTERNET network.

The fault diagnosis circuit 105 diagnoses whether the power supply is normal and whether there is an abnormality in each circuit function from the sensing chip to the LAN network, and alarms itself and notifies the LAN SERVER COMPUTER to perform appropriate measures such as an alarm.

The MICRO COMPUTER 106 compares, analyzes and judges the sensed signal with 10 numerical signals from 1 to 0 already stored and notifies the DIGITAL PULSE generating device. It also controls each circuit such as charging of battery, reliably saves and manages data, adopts a very small MICRO COMPUTER that can exchange necessary information with LAN SERVER COMPUTER, and enables software to perform remote automatic meter reading to ROM. Built.

The LAN connection circuit 107 connects the MICRO COMPUTER and the LAN network to perform a remote automatic meter reading function.

In addition, it plays a special role of connecting the battery to the charging device at a fixed time so that the battery can be supplied through the LAN network.

The power supply 108 has a built-in small battery to be used as the main power supply of the metering device of the present invention, and the charging of the battery is performed through the LAN network at predetermined times in the power supply 216 installed with the LAN SERVER COMPUTER, respectively. Stable supply

The schematic diagram of FIG. 2 is explained in full detail.

LAN SERVER COMPUTER (214) is installed in the apartment management office, and HOST COMPUTER (251) such as water supply headquarters, water supply, electricity, and GAS, KEPCO, GAS Corporation, etc. are connected to the Internet network 230 to exchange necessary information. The information automatically read in the complex is delivered promptly at the specified time or when it is needed, and the bill is issued automatically.

In the apartment complex, 211, 212, and 213 are remote automatic meter reading devices for water, electricity, and GAS of each generation, and 210 is a LAN network.

The PRINTER 215 prints the water, electricity, and GAS bills directly by receiving the command of the HOST COMPUTER of the supplier, and issues bills, thereby simplifying postal mail and reducing expenses.

In particular, whether in the apartment complex 221 or outside the complex 241, Internet subscribers can be billed via the Internet from providers such as water, electricity, and GAS, and can be settled in electronic commerce.

As described above, the indirect remote automatic meter reading device of the present invention is impossible without wired or wireless communication such as LAN and INTERNET, and is a device that can be realized only in the millennium era in 2000.

When this design is put into practical use, suppliers of water supply headquarters, KEPCO, GAS construction, etc., do not need to read the meter installed at the customer by mobilizing the meter reader. As the government announced at the beginning of 2000, if the Internet spreads to all households within four or five years, all consumers will be able to use automatic automatic meter reading as well as electronic payment. It will revolutionize business management, and all business management will be handled by COMPUTER to achieve surplus management, and the profits will of course be returned to consumers, and the effects of water, electricity, and GAS rates will be lowered. .

As a side effect, the waterworks headquarters, KEPCO, GAS Corporation, especially the Internet and telecommunication companies, have enjoyed the specialty of distributing the Internet to all households, and they make a lot of investments. Its rapid development contributes to the development of the national economy.
