Recently, it was learned from the National Patent Office that Zhejiang Zhengtai Instrument and Meter Co., Ltd. (hereinafter referred to as Zhengtai Instrument) has obtained three utility model patents. Chint Instrument pays attention to the protection of corporate intellectual property to a new level.
It is reported that the three patents obtained this time are remote dual-loop control single-phase fee-controlled smart energy meter, patent number is ZL201520063919.5, a pulse signal and analog signal conversion device, patent number is ZL201520087053.1, a Error adjustment mechanism, patent number ZL201420839859.7. It is understood that the remote dual-loop control single-phase fee-controlled smart energy meter (hereinafter referred to as the energy meter) adopts a virtual medium instead of a traditional local IC card, reduces the user control link, improves the reliability and security of electricity, and has become pre-paid. The inevitable trend of electric energy meter development. The watt-hour meter is used in conjunction with a power-sales system to provide users with modern sales and purchase services through remote internet, terminal and other media. The energy meter replaces the traditional ESAM encryption module with a software encryption algorithm, which saves manufacturing costs and increases the features such as dual-loop control and regular power-on and power-off. Currently widely used in colleges, shopping malls, enterprises and institutions.
The acquisition of these three patents is an affirmation of Chint Instrument's scientific and technological innovation capabilities. The acquisition of these patents will further stimulate the enthusiasm of Chint Instrumentation engineers and technicians for their inventions.
