BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a meter reading apparatus for measuring the amount of electricity, water, gas, and the like, and more particularly, to a meter reading system equipped with a communication type remote meter equipped with multiple protocols and a meter reading method using the same.
Generally, a meter is installed in the consumer building such as a home or a factory to indicate the usage amount of electricity, gas, water, etc., and the supplier checks the amount of the supply through the meter reading device of the prisoner and charges the usage amount.
Accordingly, the supplier regularly checks the meter reading device installed in the customer's building for charging. In the past, a meter probe used a method of visually determining each meter reading device, recording the numerical value by hand, or inputting a key to a hand terminal.
However, in such cases, there is a possibility that a mistake may be recorded or entered by mistake, which has resulted in complaints of false charges.
In addition, the exact amount of usage must be accurately measured to impose an accurate charge.
Therefore, the meter reading apparatus should accurately measure the usage amount. At present, researches on methods for accurately measuring the amount of use using a meter reading device are actively being carried out.
In the collection of meter reading information, the so-called digital meter reading method, in which the meter reading quantity is transmitted directly from the meter to the digital data, occupies a large portion in the field of the remote meter reading.
However, in the past, there were different protocols for each manufacturer of the equipment meter, so it was troublesome to unify the meter with the product sold by a single manufacturer at the time of system configuration, and the maintenance, There has been an inconvenience in that the product must be replaced only with the product of a specific maker in a situation where the product needs to be replaced.
In particular, since only a proprietary protocol of a manufacturer is used in the past, it is not possible to use a communicating facility meter sold by a manufacturer other than a manufacturer in a compatible manner, and all of the gas, water, hot water, It is only possible to link them.
Also, since a communication meter type remote meter for a facility meter of one manufacturer can use only a model having only a protocol of a manufacturer's meter to be used for meter reading system construction, the universality and compatibility are remarkably lowered, There are many restrictions on the selection of manufacturers of southern equipment meters.
Furthermore, during the operation of the meter reading system, it is troublesome to purchase and replace a product sold by a specific manufacturer in the exchange due to breakdown or breakage of gas, water, hot water, heating meter and remote meter reading device.
It is an object of the present invention to provide an apparatus and method for enabling compatibility with various kinds of facility meters equipped with different protocols according to the manufacturer by using a remote meter using an algorithm capable of selecting protocols that can be automatically interlocked while loading multiple protocols The present invention also provides a meter reading system equipped with a communication type remote meter equipped with multiple protocols and capable of checking the convenience of configuration, maintenance, and maintenance of the meter reading system, and a meter reading method using the same.
In order to achieve the above object, a meter reading system having a communication type remote meter equipped with multiple protocols according to the present invention includes a watt hour meter for measuring a cumulative power consumption amount for each household, A communication type remote meter for collecting the meter reading information of the meter by mounting a plurality of protocols, and a control unit for receiving the meter reading information collected from the communication type remote meter reading unit And an upper application that records, manages, maintains, and displays the application.
