Description

Direction sensing apparatus of numeric wheel for Remote telemeter

According to the present invention, a metering magnetic is attached to one unit wheel among a plurality of number wheels, and when a metering magnetic is detected in a first sensing unit provided at a predetermined position adjacent to the number wheel, the generated pulse is accumulated in the metering data of the memory unit. 10 unit number wheels per 1 rotation of 1 unit number wheel are interlocked and rotated at a predetermined angle, and adjacent number wheels are interlocked to display meter reading data.When the meter reading request pulse is received from the remote meter through the transmitter / receiver, The present invention relates to a number wheel reverse rotation sensing device of a remote meter reading meter that transmits meter reading data to a remote meter, and a method and an error correction method. In particular, the meter reading data physically read according to the rotation of the number wheel of the meter reading meter The pulse generated by the metering magnetic attached to the metering meter is applied to the meter reading data according to the forward and reverse rotation of the number wheel. Accurate metering by minimizing the error between meter reading and remote meter reading data by performing the calculation with acid and subtraction, enables meter reading data by remote meter reading to be trusted by the customer. The present invention relates to a number wheel forward rotation detection device of a remote meter reading instrument that enables accurate billing notification.

In general, the conventional meter reading method for water, gas, electricity and the like consists of a process of the meter readers to directly check the meter, check the meter value, record the checked data, and then input the recorded content into the computer.

If an error occurs while performing this process, the problem of error caused by the consumer or the country may be lost. In addition, these meters need to be checked and exchanged regularly, but since there is no information on when to replace them and regular inspections, the parts purchased for exchange and inspection are left unattended and waste a lot of money.

Therefore, in order to solve the above problem, various methods of remote meter reading system have been developed.

For example, a method has been developed in which a meter reader visits a customer by using a handy terminal and inputs meter reading data on site. However, this method has the advantage of shortening the input process of the computerized data, but it is not effective due to the disadvantage that it does not contribute to the reduction of labor costs due to the meter reading directly enter the data by the meter reader.

In addition, as an improved meter reading method, as shown in FIGS. 1 and 2, a magnetic 3 is attached to any one of the number wheels 2 of the meter 1, and the rotation of the number wheels 2 is sensed. The unit 4 generates a pulse, which is accumulated in the counter 5 and stored in the memory unit 7 by the processing unit 6 to display the meter reading amount. A remote meter reading meter (1) for transmitting and receiving remotely has been proposed and used.

However, the remote meter reading meter 1 is a configuration in which the magnetic 3 is attached to the number wheel 2 in order to allow the sensing unit 4 to detect the rotation period of the number wheel 2 as described above. If there is a magnetic material in the adjacent position from the remote meter reading meter (1) causes a serious error in the meter reading data, there is a problem that less than the actual amount of use or excessive metering.

In addition, even if the remote meter reading meter (1) is installed outdoors, as the industry develops, various electronic devices are installed, and powerful electromagnetic waves are scattered around the living area. As a result, an error occurs in the meter reading.

In particular, since the sensing unit 4 generates a pulse only when the magnetic unit 3 attached to the one-unit numeric wheel 2a is close to the sensing unit 4, the one-unit numeric wheel 2a is rotated in a forward direction and the pulse is rotated. Error occurs due to manipulation and error.

In the meantime, the accurate meter reading refers to a meter reading that does not cause an error between the meter reading data of the display part and the memory part displayed by rotating the number wheel, and in the customer, the meter reading amount is artificially manipulated or the meter is reversed. The reinstallation of the reading data and the display of the display unit by the number wheel may be inconsistent with each other. In this case, since accurate metering is not performed, quantitative charging is not possible, which causes a problem of informing the recognition.

The present invention devised to solve the above problems can verify the forward rotation and the reverse rotation of the one-digit number wheel, and if the meter reading is cumulatively displayed as the number wheel is rotated forward, the meter reading data of the remote meter reading part also rotates forward When the meter reading is displayed as the meter wheel is rotated in the reverse direction, the meter reading data of the remote meter is also deducted according to the reverse rotation so that the physical meter data of the number wheel and the data of the remote meter are read. The purpose is to ensure that is within a minimum margin of error.

The above-described object is that the metering magnetic 103 is attached to one unit number wheel 101a of the plurality of number wheels 101, and to the first sensing unit 102 provided at a predetermined position adjacent to the number wheel 101. When the metering magnetic 103 is detected, the generated pulse is accumulated in the metering data of the memory unit 104, and the 10-unit numeric wheel 101b per rotation of the 1-unit numeric wheel 101a is interlocked and rotated at a predetermined angle. The adjacent number wheel 101 is interlocked to display the meter reading data. When the meter reading request pulse is received from the remote meter through the transmitter / receiver 105, the meter reading data accumulated in the memory unit 104 is transmitted to the remote meter. In the reverse rotation detection device of the number meter of the remote meter reading meter, the circumferential direction of the 10 unit number wheel (101b) adjacently installed so as to interlock with one rotation of the unit number wheel (101a) attached to the meter magnetic 103 Multiple checkers attached at different intervals Ticks (106) and; The second sensing unit 107 is arranged to be close to the predetermined position of the rotation radius of the 10-unit numeric wheel 101b to which the check magnetic 106 is attached to generate a pulse when the check magnetic 106 is close. )Wow; A counter (108) for accumulating pulses generated by the first sensing unit (102); When the pulse is generated in the second sensing unit 107, the forward and reverse direction of the one-digit number wheel 101a is sensed by comparing the number accumulated in the counter 108 with a plurality of forward detection numbers stored in the memory unit 104. It is achieved by the number wheel forward rotation detection device of the remote meter reading meter, characterized in that it comprises a processing unit 109.

Here, the check magnetic 106 is equally spaced apart from each other at a position corresponding to the number formed on the number wheel 101 on either side of the number wheel 101 inside or both sides, the check magnetic 106 It is preferable to store these attached numbers in ascending order in the memory section 104.

The magnetic shield plate 110 may be further provided between the first sensing unit 102 and the second sensing unit 107 to shield the magnetic force so as not to interfere with each other when a pulse is generated.

Hereinafter, with reference to Figures 3 to 5 attached to the configuration of the numeric wheel forward rotation detection device of the present invention remote metering meter as follows.

First, FIG. 3 shows only the structure of the number wheel 101 and the metering unit of the remote metering meter, and according to FIG. 3, the unit consists of 1 unit, 10 units, and 100 units from the right end to the left side of the drawing. When the wheel 101a rotates 10 times, the 10 unit number wheel 101b rotates 1 time. When the 1 unit number wheel 101a rotates 100 times, the 10 unit number wheel 101b rotates 10 times. It is configured to rotate in conjunction with.

Here, since the interlock structure of the number wheel 101 is a structure of a general gear, its configuration description will be omitted below.

The position of the '0' number formed on the surface of the one-unit number wheel 101a of the present invention is attached to the meter magnetic 103 as in the prior art so that the '0' may be clockwise (the direction may be counterclockwise depending on the setting) However, in general, when one rotation is performed in a clockwise direction, '0' rotates one turn to approach the first sensing unit 102, thereby generating a pulse in the first sensing unit 102. It can be seen that the configuration and operation is the same as the conventional configuration and operation, while the ten-unit numeric wheel 101b of the present invention is provided with a plurality of check magnetics 106 at predetermined intervals.

Hereinafter, assuming that three check magnetic 106 is attached for easy explanation and understanding of the present invention will be described.

Accordingly, the first check magnetic 106a of the check magnetic 106 attached to the ten unit number wheel 101b is attached to a position corresponding to the '1' number of the ten unit number wheel 101b and the second check magnetic unit 106a. 106b is attached to the position corresponding to the '6' number, the third check magnetic 106c is attached to the position corresponding to the '9' number.

Here, the attachment position of the check magnetic 106 may be attached to the inner diameter surface of the number wheel 101, as shown in Figure 4, may be attached in a form protruding laterally from the inner diameter surface of the check magnetic 106. This form and structure is not limited to this because it does not affect the achievement of the purpose and overall configuration of the present invention, but preferably it is preferably attached to the inner diameter surface of the number wheel 101 stably.

On the other hand, when the check magnetic 106 attached as described above, when the one-unit number wheel 101a rotates one time, considering that the ten-unit number wheel 101b rotates one division, the first check magnetic 106a Since the distance between the second check magnetic 106b and the second check magnetic 106b is numerically '1 to 6', the first check magnetic wheel 101a must be rotated five times so that the second check magnetic 106b is the second sensing unit 107. Since the third check magnetic 106c is attached at the position of the scale '9', the first unit number wheel 101a must add three revolutions (a total of eight revolutions) to the second sensing unit 107. It can be seen that the pulse is generated at.

That is, the second sensing unit 107 can know that a pulse is generated every time the one-unit numeric wheel 101a rotates 5, 8, or 10 rotations.

From the perspective of the 10-unit number wheel 101b, this action is 5 turns (pulse) when the 10-unit number wheel 101b rotates in the forward direction (when the 1-unit number wheel 101a rotates in the forward direction). Rotation (Pulse)-> 2 (Pulse)-> Counter (108) Reset to '0'-> 5 (Pulse)-> 3 (Pulse)-> 2 (Pulse)-> Counter (108) '0 It can be seen that a pulse occurs at the period of 'Reset to ...'. If the 10-unit numeric wheel 101b rotates in the reverse direction, 2 turns (pulse)-> 3 turns (pulse)-> 5 turns (pulse) A pulse is generated in the second sensing unit 107 at a cycle of ...), and this time, the counter 108 and the meter data can be subtracted in the reverse direction by detecting the reverse direction by the reverse sensing method described below.

Therefore, when the pulse is generated in the second detector 107, the processor 109 is simultaneously with the point in time at which the pulse is generated in the first detector 102. Thus, the first detector 102 and the second detector ( The pulses of the second sensing unit 107 are generated at the same time as comparing the pulses of the 107 and the number of intervals of the check magnetic 106 attached to the 10 unit number wheel 101b described above in the memory unit 104. By comparing the synchronization of the pulses according to the order, the error of the number wheel 101 and the reverse and forward rotations can be determined.

Here, when the processor 109 detects the reverse rotation of the ten-digit wheel 101b, the number wheel 101 is displayed by subtracting the value of the reading data in which pulses are accumulated by the second detection unit 107. When the meter reading amount and the meter reading amount of the meter reading data coincide with each other, and the number wheel 101 is normally rotated in the forward direction, the pulse accumulation value by the second sensing unit 107 is accumulated in the meter reading data so that the meter reading of the remote meter reading meter is performed. The error between the meter and the meter reading data does not occur.

On the other hand, when the first sensing unit 102 generates a pulse by installing a magnetic shield plate 110 between the first sensing unit 102 and the second sensing unit 107, the second sensing unit 107 is It is preferable that the first operation unit 102 is operated together so as not to generate a pulse when the second detection unit 107 generates a pulse.

A method of correcting the reverse rotation and metering error of the number wheel 101 as described above will be described in detail with reference to FIGS. 5 and 6.

First, the forward and reverse rotation detection method and the error correction method of the number wheel 101 is due to the forward and reverse rotation and the occurrence of the opulence to detect the forward and reverse rotation and to detect the occurrence of the opulence, the correction should be made accordingly, Detailed description will be described from the case where the number wheel 101 rotates in the forward direction.

As shown in FIG. 5, when the number wheel 101 rotates in the forward direction, first, a pulse is generated in the first sensing unit 102 by the rotation of the number wheel 101a and the reading magnetic field 103. At this time, if a pulse is generated in the second detector 107 even though a pulse is not generated in the first detector 102, the pulse generated in the second detector 107 is a magnetic field interference by a magnetic field toward the meter. As this occurs, the opulence has occurred, and since the 1-digit number wheel 101a and the 10-unit number wheel 101b are not rotated, the pulse of the second detection unit 107 generated at this time is ignored and the transmission / reception unit is ignored. The forward opulence correction step S6 is performed to transmit the opulence reading error code to the remote reading unit through 105 and to wait for the generation of the pulse of the first detection unit 102.

On the other hand, when a pulse occurs in the first sensing unit 102 as described above, one unit pulse is accumulated in the counter 108 of the memory unit 104 (hereinafter, the counter 108 is referred to as Count1 in FIG. 5). The pulse accumulation step S1 is performed. First, since the initial value of the Count1 (Default) is 0, 1 is added to 1.

In addition, while the pulse is generated in the first sensing unit 102, the pulse is not generated in the second sensing unit 107, and the 10-unit numeric wheel 101b is rotated by one unit of the number wheel 101a. It can be determined that the check magnetic 106 of the 1, 6, and 9 scales is not close enough to generate a pulse in the second sensing unit 107.

Therefore, when the number of forward detections sequentially designated among the number of forward detections stored in the memory unit 104 is greater than the number of Count1, the first monitoring unit waits for pulse generation. Referring to FIG. 5, the initial value of Count2 is 0. , B is an array that stores forward detection numbers 1, 6, and 9 sequentially. The first forward detection number to compare with Count1 is assigned to Count2_1, and its value is 1, which is the value of B [0]. In operation, the scales of all the number wheels 101 are set to 0. When the meter reading starts, 1 is added to Count1 as the number wheel 101a rotates one unit.

At this time, when the 10-digit number wheel 101b rotates by one scale so that the check magnetic 106 approaches the second sensing unit 107 and generates a pulse in the second sensing unit 107, the processing unit 109 detects the forward direction. If the number Count2_1 is equal to the number of Count1, 1 is added to Count2, or if Count2 is greater than 2, the initial value 0 is assigned to the memory unit 104 to detect the number of forward detections B [0], B [1], and B. [2]) is sequentially performed, the detection number specifying step S4 is performed. If Count1 is greater than 9, 10 is added to the meter reading data of the memory unit 104 and the Count1 is initialized to 0. A data integration step S5 for waiting for the generation of the pulses of the first monitoring unit is performed.

On the other hand, when a pulse is generated in the first monitoring unit and no pulse is generated in the second monitoring unit, the number of forward detections Count2_1, which are sequentially designated among the number of forward detections stored in the memory unit 104, is smaller than the number of Count1. If the count is greater than or equal to Count2_1, subtract 1 from Count1 and perform a forward misreading correction step S2 of waiting for a pulse of the first monitoring unit.

That is, when Count1 is greater than or equal to the number of forward detections, since the pulse generated by the first sensing unit 102 is an off-pulse, the value of Count1 increased by 1 is subtracted so that the generated pulse does not accumulate in Count1, and Count2_1 and When Count1 is the same, the first sensing unit 102 and the second sensing unit 107 are limited only when a pulse occurs at the same time.

In addition, even if a pulse is generated in the second sensing unit 107 in conjunction with the generation of a pulse in the first sensing unit 102, the number of forward detections sequentially designated among the number of forward detections stored in the memory unit 104 is Count1. If it is not equal to the number, since it is a pulse generated by the reverse rotation, the processor 109 transmits the reverse rotation error code to the remote meter, and the reverse rotation correction step S3 is performed such that the error correction according to the reverse rotation is performed as shown in FIG. 6. Perform

Here, in the reverse rotation correcting step (S3), even when the number wheel 101 rotates in reverse, the first sensing unit 102 generates a pulse every one rotation, so that the number wheel 101 of the remote meter reading meter is used for the generated pulse. In order to ensure that the reading amount indicated in the above) and the reading data of the memory unit 104 match as accurately as possible, the reading data should be subtracted in the reverse rotation.

Therefore, if a pulse is generated in the second detector 107 even though no pulse is generated in the first detector 102, the pulse generated in the second detector 107 is not affected by the magnetic field interference by the magnetic field. Since the 1-digit number wheel 101a and the 10-digit number wheel 101b are not rotated as they have occurred, the pulse of the second detection unit 107 is ignored and the transceiver unit ( The reverse opulence correction step S12 is performed to transmit the opulence reading error code to the remote reading unit through 105 and to wait for the generation of the pulse of the first detection unit 102.

On the other hand, as described above, when a pulse is generated in the first sensing unit 102, the pulse is rotated one direction in the reverse direction, so that one unit pulse is transmitted to the counter 108 (hereinafter, the counter 108 of FIG. 6) of the memory unit 104. A pulse subtraction step (S7) of subtracting Count1) is performed. Initially, the initial value of Default Count1 (Default) is 9, and the initial value of Count1 is variably changed when the motor rotates one direction from the forward direction to the reverse direction. There is no need to specifically limit this.

In addition, when a pulse is generated in the first sensing unit 102, but no pulse is generated in the second sensing unit 107, the 10 unit numeric wheel (1 unit number wheel 101a is rotated 1 direction in the reverse direction). 101b) may determine that the check magnetic 106 of 1, 6 and 9 scales are not close enough to generate a pulse in the second sensing unit 107.

Therefore, when the number of forward detections specified in the reverse order among the forward detection numbers stored in the memory unit 104 is smaller than the number of Count1, the first monitoring unit waits for the generation of a pulse. It is an array that stores numbers 1, 6, and 9 in order. The initial number of forward detections to be compared with Count1 is assigned to Count2_1, and its value can be changed when the rotation is changed from forward rotation to reverse direction. It is not.

Hereinafter, assuming that 1 is the value of B [0] at the time when the direction of the number wheel 101 is changed, 1 is subtracted from Count1 as the unit wheel 101a rotates once.

At this time, when the 10-digit number wheel 101b rotates by one scale so that the check magnetic 106 approaches the second sensing unit 107 and generates a pulse in the second sensing unit 107, the processing unit 109 detects the forward direction. If the number Count2_1 is equal to the number of Count1, the number of forward detections B [0], B [1] and B [2 is reduced by subtracting 1 from Count2 or allocating 2 if Count2 is less than 0. ]) Is performed in reverse detection number designation step S10, and if Count1 is less than 0, subtract 10 from the reading data of the memory unit 104 and assign 9 to Count1. A data subtraction step S11 for waiting for the generation of the pulses of the first monitoring unit is performed.

On the other hand, when a pulse is generated in the first monitoring unit and no pulse is generated in the second monitoring unit, the number of forward detections Count2_1 specified in the reverse order among the number of forward detections stored in the memory unit 104 is greater than the number of Count1. If it is small (when Count1 is greater than Count2_1), 1 is added to Count1, and the reverse false reading correction step S8 is performed to wait for the pulse of the first monitoring unit.

That is, when Count1 is less than or equal to the number of forward detections, the pulse generated by the first detection unit 102 is an opulence, so that the value of Count1, which is decreased by one, is increased by one, so that the generated pulse is not subtracted from Count1, and Count2_1 and If Count1 is the same, this is not the case since the first sensing unit 102 and the second sensing unit 107 are generated only when a pulse occurs at the same time.

In addition, even if a pulse is generated in the second detection unit 107 in conjunction with the generation of a pulse in the first detection unit 102, the number of forward detections specified in the reverse order among the forward detection numbers stored in the memory unit 104 is Count1. If it is not equal to the number of times, since this is a pulse generated by the forward rotation, the processor 109 transmits a metering error code in the forward direction to the remote meter, and the forward rotation correction step for performing error correction according to the forward rotation as shown in FIG. S9) is performed.

As described above, the present invention provides a first sensing unit by a plurality of check magnetics 106 attached to the meter magnetic 103 attached to the one-unit numeric wheel 101a and the ten-unit numeric wheel 101b at different intervals. When the pulses are generated at the 102 and the second sensing unit 107, the pulses are sensed in the forward and reverse directions by comparing the pulses with each other. Opulses can be corrected.

Therefore, the physical metering data by the number wheel 101 and the metering data accumulated in the memory unit 104 exceed the five divisions of the maximum 10-digit number wheel 101 by the erroneous reading and the opulence correction as described above. If the number wheel 101 rotates in the forward direction, the meter reading data is added, and if the number wheel 101 rotates in the reverse direction, the meter reading data can be subtracted, and the 10 unit number wheel 101b has different intervals. It is possible by being able to detect the forward rotation and the reverse rotation of the number wheel 101 by a plurality of check magnetic 106 is attached to.

As described above, the present invention, when the number wheel of the remote meter reading meter rotates for any reason, the pulse generated by the reverse rotation does not accumulate in the meter reading data so that the accurate meter reading is achieved, the remote indicator and the remote meter By allowing accurate metering data to be transmitted, the customer can be metered as much as he or she used, thereby improving the reliability of the remote meter and sending the meter error code to the remote administrator at the same time as the error occurs. In the remote area, it is possible to quickly identify and respond to the location of the customer where the error meter occurs.
