Description

A passive remote intelligent water meter

technical field

The invention discloses a water meter, which belongs to the category of flow meters, and in particular relates to a passive remote transmission intelligent water meter.

The present invention and the utility model patent application named "a passive remote intelligent water meter" belong to the same applicant as stipulated in the first paragraph of Article 9 of the Patent Law. If the utility model patent right obtained earlier has not expired, the applicant is willing to give up the utility model patent right and obtain the invention patent right.

Background technique

Water meter is a commonly used water consumption measuring instrument. Since the meter reading of tap water meters in most residents' homes is still artificially estimated, and the meter has not been actually read to the household, most residents feel quite inconvenient. In order to solve this problem, an additional remote transmission water meter (also known as a data transmission type water meter, hereinafter referred to as an electronic water meter) has appeared on the market, and has begun to be used in some areas. This kind of electronic water meter can realize the function of copying water meter data from a certain distance without entering the user's house, which greatly facilitates the water supply company and water supply users, and basically solves the above-mentioned problems. However, while the existing electronic water meters provide convenience for everyone, there is a big hidden danger. This is that the electronic water meter must use a power supply during the working process. Once a power failure occurs, the stored data will not be counted. If it is lost, it will affect the interests of water companies and users. At present, most electronic water meters use batteries as their system power supply. Although the manufacturer has repeatedly stated that the battery can maintain a service life of 7-8 years, no one can tell when the battery will run out of power. Once the battery fails to supply power, Then the electronic water meter will not get the water meter data, which will be a great loss to the water company.

Existing electronic water meters still have low reliability, such as water leakage, resulting in electronic components not working properly, high maintenance costs, and the use of batteries cannot fundamentally solve the problem of difficult meter reading.
