The memory back 2 is an integrated circuit memory with a built-in battery, and retains its stored contents even when no external power is supplied. The memory back 2 can be inserted into the slot 8 of the main body l, and in the inserted state is connected to the interface 16 by the connector 8, and the 0PU
The memory back 2 also sends and receives data to and from a host computer 8 via a connector 8 (e.g., a computer installed at a public utility's evacuation center, which is used to send and receive data to and from each customer in a predetermined area). 1111), which stores past meter readings, fecal volume, average usage, etc.), and exchanges data with the upper 1111 systems.

The book is equipped with a keyboard 5. this keyboard 6
consists of numeric keys 1011 (0 to g are displayed on the surface) and several function keys F1' to F (511ii in the illustrated example). - is used for inputting numerical data such as tIl and readings taken from the totalizer by the needle machine. The function keys are used to round up instructions such as checking, displaying, and printing data.

The display device 6 displays input data, the amount of electricity, the name of the consumer, etc.

The printer 7 prints the current month's meter reading value, usage 1, etc. on a meter reading slip for informing patrons on demand.

A program memory (ROM) 10 stores basic programs, and a memory (RA v ) u stores application programs (for example, used when performing special processing for a particular customer).

The memory 11 also temporarily stores data when the 0PU9 performs various processes.

0PTIF (central processing unit) 9 is 10 grams (
It operates according to the program stored in the ROM (ROM) and, if necessary, according to the application program stored in the memory 11, and controls other devices, calculates the usage amount, checks data, etc.

Input via the Φ-board 6 is input to the keyboard controller 1
Further, the display on the display 6 is driven by the driver 15, and the printing by the printer 7 is controlled by the printer controller 13, respectively.

The connector 4 is used for exchanging data and programs with an external computer, and is connected to the 0PU 9 via an interface 12.

When reading the meter each month, the meter reader has several memory bags 2
will be given to you. Each of the memory backs 2 contains customer codes,
Information such as contract type, customer name, meter reading value for the previous month, usage amount for the previous month, average usage amount for the past 8 months, total meter model, functions, etc. is entered from the host computer and stored. It is something. The above-mentioned data for each consumer is about 5oB (bytes) in total, and the memory pack 2 has, for example, 8KB to 32KB. Therefore, 1
Data about 150 to 600 consumers is written in one memory hack 2. Therefore, the number of meter readers is 150 to 60.
It is sufficient to replace the memory bank 2 once every time the meter reading for the 00 layer important residents is completed.

At each customer, with the corresponding memory bag 2 inserted into the slot 8, the meter reader first inputs the customer number using the keyboard 5. Then, the 0PU 9 inserts the data of the corresponding customer number from the memory back 2, and causes the display 6 to display the customer name, contract type, etc. After confirming this display, the meter reader reads the meter and inputs the meter reading value into the keyboard 6. Then, the input meter reading value Fi
Since the meter reading value is displayed on the indicator 6, the meter reader can check whether the meter reading value has been entered correctly and can re-enter it if it is incorrect.

Next, press the calculation key among the function keys F and ~1. Then, 0PU9 calculates the usage amount for the current month from the input meter reading value and the previous month's meter reading value read from memory back 2. Display it on the display 6. Also, if you press the check key among function keys F and ~F1, you can compare the calculated stool volume for the current month with the usage volume of the previous month read from memory back 2 and the average value of past usage volume. By comparison, it is determined whether there is any abnormality or change in the amount of stool for the current month, and the result is displayed on the display 66. If there is no foreign material, the function dP-y, ~1
．． While printing, press -.

Then, the first meter reading shift and usage amount for the current month are printed on the meter usage slip by the printer 7, and the meter reading values for the current month are stored in the memory back 2.
is memorized. The printed bond note is acquired by the demander.

My friend, the meter reader, who has made multiple meter readings at home in this way, takes several memory bags 8 to the office and puts them there.

The memory back 2 is sequentially integrated into higher-level computers, and the memorized first shift of meter reading for the current month is transferred to the higher-level computer.

The host computer calculates data based on the direct meter reading data collected in this way (the meter reading value of the previous month,
#Average value of f1t) When reading the meter in the 0th month, in which fr is performed, charges are calculated, and other miscellaneous processing is performed, the updated + fr data is recorded in memory back 2. .

If the ratio with the previous month's data is determined to be f4 yo bs*, the data is input again, and if it is determined to be abnormal again, the meter reading system is not handed over to the customer, but the data is taken back to the office and countermeasures are taken.

If the meter reading order is predetermined, you can press one of the function keys IP1 to ν on the keyboard 5 to select the next *
*In addition to displaying the name of the house, it is also possible to prepare for inputting the meter reading value of the customer.

Although the above description has been made assuming that meter reading is carried out once a month, the present invention is applicable not only to cases in which meter readings are carried out once a month, but also to cases in which meter readings are carried out at other predetermined periods, or in cases in which meter readings are carried out irregularly. can also be applied.

Friend, the average value of past usage is not limited to the pure average value.

Furthermore, the present invention is applicable not only to the meter reading of an electric power meter, but also to gas, water, etc.

Furthermore, as a battery for the data memory 2, a battery such as Ni-Cd is used.
It is also possible to use a secondary battery and connect it to a host computer for reading and writing data so that photoelectricity is automatically generated during operation.

In addition, although a removable memory back 2 is used as data memory, the memory built into the main body l is used, and a cell for data memory is provided separately from the battery for the main body. Data may be exchanged with the host computer via the connector 4.

〔Effect of the invention〕

As described above, according to the present invention, a meter reader can:
In addition to reading the meter's pointer, you only need to input the meter reading value using the key, and input for commands to calculate, check, and print. There is no need to perform comparisons, etc., and the contents input using the keys are displayed on the display. Therefore, the amount of work at the customer's site is reduced and the risk of erroneous recording is reduced. In addition, the collected meter reading data can be directly entered into the upper level, streamlining operations. In addition, although the main body of the meter reading device is powered by a battery, it is possible to
