Abstract

The embodiment of the invention provides a rechargeable flow instrument. The rechargeable flow instrument is applied to a system containing an instrument bus and comprises a bus connection unit which is connected with the instrument bus and used for acquiring power supply current from the instrument bus and converting the power supply current into transistor-transistor logic level (TTL), a constant-current voltage stabilizing unit used for converting the TTL into constant current, and a power source managing unit used for converting the constant current into charging current of a rechargeable battery. By arranging the constant-current voltage stabilizing unit, the power source managing unit and the rechargeable battery, the rechargeable battery can supply power to the flow instrument when a power failure happens to the instrument bus, besides, the electric quantity of the rechargeable battery can be restored, replacement is not needed, maintenance is easier, and work strength is smaller.

Description

technical field [0001] The invention relates to the technical field of flow devices, in particular to a rechargeable flow device and a charging method. Background technique [0002] During the use of electronically controlled flow devices, electric energy is needed to maintain the normal operation of the flow devices, and electric energy is required to drive the valve opening and closing of the flow devices and the statistics of water consumption. Existing flow devices are powered by dry batteries. As the usage time increases, the battery power decreases, and the flow devices cannot work normally. It is necessary to pay attention to the battery power at any time and replace the battery when the battery power is low, which brings inconvenience to the use and maintenance of the meter. . Therefore, how to solve the power maintenance problem of the electric meter is a major issue currently faced. Contents of the invention [0003] In view of this, the purpose of the embodime...
