I. Field of the Invention
This invention is a type of system and method of remotely videoing meter readings. Specifically, it refers to a type of system and method of meter recording that uses video to record the figures on the meter and then sends it to the remote data processing system for processing and calculation.
II. Description of the Prior Art
Traditional meter reading method uses manual method to read and record meter such as public electricity meter, public water meter, gas meter, etc. at each household. The meter reader has to read and record the meter at every household. Travelling time is increased if the household is located in far-flung areas. Not only is this method inefficient, but depending on the meter reader to read and record the meter will also easily result in problems in data processing later due to data error.
As a result, a type of remote meter reading product that improves the traditional method can be seen on the market currently. It combines the meter with the communication module at the household end to form an entirely new product. The meter data is sent for remote processing by the communication module at the household end. Labour and cost can be reduced. However, construction of this type of product is more difficult, as installing this product requires dismantling every group of original meter. Moreover, the accommodations in most parts of cities nowadays are all apartments. Their meters are all concentrated in a certain area of the building. If the size of this type of product is too big to be installed at the original location, all the meters have to be dismantled and pipelines have to be reinstalled in order to install this product, increasing the difficulties and costs of construction by a great extent. Furthermore, when using it with the meters in other systems, such as the various inspection and testing facilities in factories, this product has to be redesigned to meet requirements. The inspection and testing facilities even have to be redesigned or purchased, increasing costs by a great extent.
For example, patent bulletin number 580643—remote wireless meter reading method and system, the product has to be redesigned for every type of meter and measuring system and the system has to be completely dismantled and reinstalled. A new set of measuring system even has to be repurchased. The money invested in this system could far exceed the reduction in costs and is not economically effective and beneficial.
In view of the foregoing, this invention provides “a type of remote video meter reading system and method”. Not only can labour costs be saved, but this invention can be installed freely under the condition of no change to the original configuration of the meter measuring system. This invention reduces the difficulties of installation and achieves the benefits and convenience brought about by remote meter reading.
The main objective of this invention is to provide a type of remote video meter reading system and method, using videoing method to record the figures on the meter, and then sending the recorded figures to the remote data processing system for processing and calculation.

Therefore, to achieve the foregoing objectives, this invention provides a type of remote video meter reading method, comprising the below steps:
This filing will be better understood from the drawings and detailed description below.
Referring to
A noteworthy point is that the meter data videoed by the video module 10 described above could be digital image data. Furthermore, the video module 10 could comprise an image acquisition component 15 using either optical CCD component or CMOS component to video the figures indicated on the meter. Other technologies that can be used for the image acquisition component 15 also lie within the scope of the claims.
A noteworthy point is that the communication medium at the household end 50 of the communication module at the household end 20 described above, as well as the communication medium at the data processing end 55 of the communication module at the data processing end 65, could be either wire communication technology or wireless communication technology.
