Description

Meter-reading module structure for remote telemeter

The present invention relates to a structure of a meter reading module for a remote meter reading meter including a meter to read the amount of the predetermined substance passing through the inlet part of the meter to the outlet part, in particular, the abnormal magnetic force generated in the sensing unit causes the reed switch to malfunction This prevents erroneous meter reading, so that metering can be done according to quantitative meter reading, and by standing up the battery so that the '+' terminal of the battery can be placed on the upper part, the long life of the meter module It relates to the structure of the metering module for a remote metering meter that enables this.

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, various methods of remote meter reading system have been developed to solve this problem.

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 cost due to the direct meter reading.

In addition, the improved metering method attaches a magnetic to any one of the number wheels of the meter, generates the rotation period of the number wheel as a pulse signal, accumulates this pulse signal, displays the meter reading, and transmits and receives remotely. A remote meter reader was proposed and used.

However, since the pulse generator of the remote meter is a magnetic attachment to the number wheel to detect the rotation period of the number wheel as described above, if there is a magnetic material in a position adjacent to the meter, serious error in the meter reading data The problem occurs that the meter is read less than the actual usage or excessively read.

In addition, even if the meter is installed outdoors, as the industry develops, various electronic devices are installed, and powerful electromagnetic waves are scattered around the living area. An error will occur.

In addition, in the past, the meter and the remote meter are far away from each other, so as to prevent the inconvenience of the installation that must be connected to the remote meter by extending the pulse line from the meter, and to prevent the breakage of the pulse line and interference from the external environment, Because of the influence of humidity, etc., this also acts as a problem causing a malfunction of the device.

On the other hand, an improper arrangement of the substrate and antenna, including a transceiver and a memory, which transmits the metered data remotely and receives a control signal, may cause interference by electromagnetic waves, thereby preventing the transmission and reception of a remote meter. It acted as a problem of deterioration.

The present invention devised to solve the above problems is to protect the external environment by embedding the meter module in the case and at the same time to prevent mutual interference between each accessory and element to improve the communication quality of remote transmission and reception, Its purpose is to prolong its lifespan so that stable use can be achieved for a long time.
