Description

Description: FIELD OF THE INVENTION The present invention relates to a portable meter-reading data collecting and processing apparatus used at the time of meter-reading work of each customer such as water, gas and electric power.

[Background of the Invention]

In the business management of the industry that involves the meter reading business of meters installed in each customer of water, gas, power, etc., charge calculation that occurs after the meter reading data collection, billing process, through financial institutions Computers have been introduced and used for charge transfer processing and various statistical processing, and are being mechanized and rationalized. However, from the collection of meter reading data at each customer,
The series of operations from the card punch input to the computer of this data still depends on human naval tactics centering on handwritten information transmission, and mechanization and rationalization are extremely delayed, and its solution is desired. Below, the system and its operations that are currently being performed will be described by taking the most common water meter reading as an example.

In the current water meter reading management system, most of the information and data such as the address, name, customer number, meter number, transfer account number of charges, past guideline value, and usage amount of each customer are stored in the central computer for management. Stored in a file. A series of business operations related to charges, statistical processing of usage (by caliber, by area, etc.), data processing for replacement management of meters that are regularly replaced, and the previous guideline value for each customer The central computer is the center for the process of creating a "notification card" for meter reading, which is printed out, and depending on the customer, the process of creating the previous charge transfer notice. On the other hand, in the meter reading work of each customer by the meter reading staff, a so-called “meter reading ledger” is commonly used. This meter reading ledger is generally grouped into one leaf for each customer, and has almost the same information and data (address, address, etc.) as it is stored in the file of the central computer.
Name, ... usage amount, etc.) is printed or described. In addition, the meter-reading ledger is a leaf for each consumer, but is classified according to the meter-reading area, arranged in the order of meter-reading within the area, that is, in the order along the route when the meter-reading staff goes around, and is grouped into one book for each area. There is. The information and data described in the meter reading ledger match the file of the central computer, but this is because the contents of the meter reading ledger are input to the central computer and the file is configured.

Next, a series of processing contents from the meter reading work of the customer by the meter reader to the input of the obtained data to the central computer will be described.

First of all, the meter reader prints the “meter reading ledger” corresponding to each consumer in the meter reading area, the “notification card” on which the address, name, and the guideline value at the time of the last meter reading were printed, and the account transfer content of the last usage fee. Carry the account transfer notice "and other necessary instruments for meter reading and start meter reading work according to a predetermined order. At each customer's house, first read the guideline value from the meter this time, enter it in the meter reading ledger corresponding to that customer, and then calculate the difference from the previous guideline value, that is, the usage amount, enter it in the meter reading ledger, and exactly the same. Next, transfer the contents to the notification card corresponding to the customer. The meter-reader then checks whether the amount of usage obtained is an appropriate value or not. This check is carried out by comparing it with the amount of past usage listed in the meter-reading register, but one year ago The amount used in the same month, the amount used last time, and the amount used before last are mainly compared. By this check, the meter reader
If you make a mistake in reading the meter, make a mistake in the entry, or make a mistake in the calculation, correct it immediately. At that time, if there is a large deviation from the past usage despite being correct, investigate and pursue the cause from the perspective that the cause is water leakage due to equipment failure in the middle of piping or customer's house. To do. The actual situation is often due to water leakage. If the cause is a water leak, write that fact in the meter reading ledger and clearly indicate that the value is an abnormal value. When the above is completed, the meter reader's seal is placed in the meter reader column of the notification card, the notification card and the account transfer notice are placed at the customer's house, and the meter reading work for one house is completed. Then, the same work is repeated for the next predetermined customer. In the middle of meter reading, there are cases where meter reading is impossible for some customers due to special circumstances (for example, burying a meter, releasing a dog, etc.). In this case, it is common to place a contact sheet stating that meter reading is not possible at the customer's house and return it to the Waterworks Bureau for approval in consideration of past usage records. The process of meter-reading is different depending on the region, and in consideration of the past usage record on the spot, there is a case where the information card is filled in with the "estimated value" clearly specified and left at the customer's house. In this way, when the meter readings for all the customers scheduled in the area are completed, the meter readers return to the Waterworks Bureau and look at the meter reading ledger to make sure that the meter readings in the area have been performed without omission, and the usage calculation is incorrect. Check if there are any. Leakage of meter readings We perform meter readings again for customers and make corrections for calculation errors. The leaks of meter readings, the check of usage amount, and the re-reading of meter-reading leaks should not occur due to the check at each customer's home because the order of meter reading by each customer is originally decided. However, in reality, despite repeated checks, meter reading omissions, calculation errors occur, and this is one of the things that is desired to be solved. On the other hand, regarding the above-mentioned leaking customers and customers who cannot read the meter, the past 2-3
An appropriate estimated value is set while looking at the actual usage data for the same time period and one year ago, and this is used as the set value. That is, for the customer, this certified value is treated as the usage amount. In this way, the meter reading for all the consumers in the meter reading area is completed, and the meter reading book in which the final meter guideline value and the usage amount are entered is submitted to the Waterworks Bureau, and the job of the meter reading staff is completed.

The meter reading ledges for each area submitted by each meter reader are compiled and delivered to the calculation center. The contents written in the meter reading ledger are transferred to the punch card by the key puncher of the calculation center, and input to the central computer through the card reader. The contents punched into this card are not all of the items listed in the meter reading ledger, but at least the customer number that can be determined to be each customer, the current meter guideline value, the usage amount, etc. are included. The central computer calculates the usage amount by subtracting the previously stored previous pointer value from the input current pointer value, and checks the result against the input usage amount to check for punch errors and meter reading book entry errors. ing. The meter reading ledger is brought back to the calculation center after repeated checks, but in reality, there are errors in description and calculation. Moreover, it cannot be said that there are no punch mistakes made by key punchers, and at the same time it speaks of the imperfections caused by human intervention, and at the same time the solution is desired.

Although the above description is an outline of the meter reading work in the case of using water as an example, almost the same processing is performed for gas and electric power.

In such a conventional collection and processing system of meter reading data for water, gas, electric power, etc., there is human intervention from the reading of the meter pointer value by the meter reader at each customer's home to the punch card making by the key puncher. Therefore, there are input mistakes, calculation mistakes, punch mistakes, etc., and the reliability of the data becomes low. Moreover, it takes a lot of labor and time to check the data repeatedly by the meter reader in order to reduce the mistakes. become. In addition, since a great deal of labor and cost are required for card punching, and moreover, punching work is intensively performed after meter reading, it is difficult to secure this key puncher, which is generally required especially in small computing centers. I won't get it. Furthermore, in order to check for punching mistakes and mistakes in entering the meter reading ledger, the central computer is used to calculate the amount of usage based on the current input guideline value and the previously described previous guideline value, and to compare this result with the currently input use amount. Inherently unnecessary processing and costs are incurred. Moreover, since the meter reading ledger is limited in space, it is generally possible to enter only data for two to three years and is updated regularly. However, meter reading always requires past usage data, so even if you switch to a new meter reading book, you must bring your old meter reading book for a while, which not only burdens the meter reading staff but also leads to a decrease in meter reading efficiency. I am Further, when considering only water meter reading, the water leak determination is left to the meter reading staff, and there is a great risk that the meter reading staff may leak an abnormal value check due to water leak.

On the other hand, creating a bill for gas or electricity with a portable billing machine using a microprocessor is disclosed in, for example, Japanese Patent Laid-Open No.
It is known from Japanese Patent Publication No. 56-68889. However, there is a problem in that what the display device should display on the screen is not stipulated and the reliability is not necessarily high. Japanese Patent Laid-Open No. 58-155498 discloses a keyboard, a memory for storing past data and a current meter reading value, a usage amount calculation device, in order to prevent an entry error at a customer site and an input error on a punch card. A portable meter-reading device equipped with a display and a printer is proposed. However, it does not consider how to deal with the case where the meter reading by the customer cannot be read.

First, in order to start the meter reading work of the first consumer, the clear key of the keyboard 21 is operated. This calls up the information and data for the first house, and the liquid crystal display 19 displays the meter number (44971), name (Hitachitaro), and the previous meter pointer value (3977) as shown in FIG. 6 (a). , It becomes the state of waiting for the input of the current meter pointer value. Next, the meter-reader reads the pointer value from the meter of the customer and uses the ten keys 0-9 of the keyboard 21 to input the pointer value. The display of the display 19 after the current meter pointer value (4007) is input is as shown in FIG. 6 (b).
Next, by operating the setting key shown in FIG. 5, the usage amount (4007-3977 = 30) is calculated, and the usage amount (30) is changed to the sixth value.
It is additionally displayed as shown in FIG. When the print key of the keyboard 21 is operated in this state, the meter reading result is printed out on the roll paper 37 by the printer 17. Depending on the customer, the previously transferred transfer notice of the previous usage fee is also printed out from the central computer 1 via the meter reading data processing device 2. The printed information card and transferred notice include the customer's address, name, customer number, meter reading date, and other necessary information. With the above, the meter reading of the first customer is completed.
Next, by operating the advance key on the keyboard 21, the information and data of the next consumer that has been determined and entered in advance are called up, displayed on the liquid crystal display 19, and the meter pointer value for the second house is displayed. Waiting for input. Thereafter, by repeating the same operation as the first house, the meter reading work is performed one after another. In this way, when the meter reading work is performed, if an input error occurs, the correction process can be performed by operating, re-inputting and setting the clear key of the keyboard 21 regardless of before and after the setting. Also,
When it is desired to change the meter reading order that is predetermined by some information and perform the meter reading, it is possible to use the return key and the advance key together.

Next, a method of inputting an estimated value will be described. In the meter reading work, for some reason, the meter number cannot be read and the current guideline value of the meter must be input as an estimated value. In this case, first, it is necessary to judge the estimated value of the amount used by the customer. In the embodiment of the present invention, by operating the key operation of reference 1 (behavior), as shown in FIG.
1), name (Hitachitaro), amount used in the same month last year (4
0), the previous usage (38) is called and displayed. In addition, by operating the key operation of reference 2 (behavior), FIG.
As shown in, the pre-previous usage (42), pre-previous usage (5
0) is called and displayed. By knowing these past usage amount results, the meter reader can judge the estimated value of the current guide value of the meter and can input it. However, this value is an estimated value after the meter reader calls and judges the past usage amount of the customer,
It is necessary to print out that fact on the notification card. In this case, the setting key is operated after the estimation key of the keyboard 21 is operated, and "Sui" is displayed in the part (a) of FIG. 6 (c). As a result, this value is registered as an estimated value, and the comment "sui" as an estimated value is additionally printed on the notification card.

Next, a processing method when an abnormal usage amount occurs due to an input error, water leakage, etc. will be described. In this embodiment, a check is made by setting an expected range of usage for each customer. If the average value of the past 3 times (last time, last time before last time, last time before last time) and last month's usage amount is calculated, the range of ± 20% is used as the expected usage amount range, and if it is outside this range, In the (b) part of Fig. 6 (c), "Iyoyo" is displayed to warn the meter reader. The meter reader first confirms whether there is a meter reading value or a key input error by displaying "Ijiyo", and then corrects and re-inputs or sets if necessary. If there is no reading on the meter or there is no input error and there is an error message, operate the keys of Reference 1 and Reference 2 (behavior) in the same way as in the case of inputting the estimated value above. Predict leakage by comparing the actual volume with the actual deviation, and if there is leakage, check the check and location of the leakage. At the same time, the amount used will be certified after returning to the Waterworks Bureau.If there is no water leakage but the message "Ijiyo" is displayed, it means that the amount was used due to the special circumstances of the customer. In this case, the comment "Ijiyo" is not printed on the notification card.

Next, a process of calling each customer from the meter number will be described. As described above, the meter reading work follows a predetermined order. However, there are situations in which meter reading work by a certain customer must be performed at an arbitrary point in the work process due to forgetting of meter reading or special circumstances. In such cases,
It is necessary to call the customer in some way. The call can be made by operating the forward key and the return key of the keyboard 21, but if a certain customer is significantly out of order, the call will take a lot of time. Therefore, a call key of the keyboard 21 is provided so that the customer can be called from the meter number. When the call key of the keyboard 21 is operated, a display as shown in FIG. 8 (a) is displayed on the liquid crystal display 2, and the state for waiting for the input of the meter number is entered. When input to the meter number (12345), the information and data of the customer corresponding to the meter number (12345) is called as shown in FIG. 8 (b), and the name (Hitachitaro) and the current meter pointer value (10526) Is displayed,
It will be in the state of waiting for the input of the meter pointer value this time. Although the call from the meter number has been described above, when the customer number is used for management, the call from the customer number is also performed by the same operation.

〔The invention's effect〕

As described above, according to the present invention, it is possible to input the current meter pointer value while checking the customer's meter number, name, and previous meter pointer value on the same screen, and also to check the usage amount on the same screen. However, since setting and printing can be done, it is possible to eliminate mistakes in input and to have a reliable and reliable meter reading with a sense of security for the meter reader. In addition, when the estimated value is input, input error, water leakage, etc., the customer's meter number, name, last year's same month usage amount, previous usage amount are displayed on the same screen, and meter number, name, last-before-last usage amount, last-before-last usage amount. Since it can be called and confirmed on the same screen, the meter reading work efficiency can be improved.
