[Chinese instrument network meter patent] creative limit, instrumentation invention. Today, we introduced a national patent for invention—a water meter, a hot-air meter, and a four-in-one converter. The patent was applied for by State Grid Zhejiang Electric Power Co., Ltd., Huzhou Power Supply Company, State Grid Corporation of China, State Grid Zhejiang Changxing County Power Supply Company, and Hangzhou Xili Intelligent Technology Co., Ltd., and was authorized to announce on June 13, 2017.
Content Description
The utility model relates to the technical field of converters, in particular to a four-in-one converter of a water meter, a hot meter and a gas meter.
Background of the invention
At present, water meters, electricity meters, heat meters, and gas meters use separate acquisition devices to implement wireless meter reading. However, data collection for water meters, electricity meters, hot meters, and gas meters are installed separately at the user's office. The acquisition equipment collects data. Therefore, to collect the data of these four types of tables, it is necessary to install the corresponding four collection equipments at the user, which not only results in a high installation cost of the collection equipment. In addition, after the user purchases the four types of energy consumption, namely the required energy consumption for water, the required energy consumption, the required thermal energy consumption and the required energy consumption, the four energy consumptions purchased by the user. Between the various energy purchase fees, free interconversion is not possible, so that the users cannot freely convert each energy consumption amount after purchasing the four energy consumption amounts.
