FIG. 2 is a schematic diagram of the circuit structure of the present invention;

in the figure: the power supply circuit comprises a chip main body 1, a bus 2MBUS, a boosting module 3, a field effect device 4, a comparator 5, a communication module 6, a battery power supply module 7, a battery power supply module 8, a magnetic induction switch module 9 and an indicator light module 10.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, a wired remote water meter information acquisition device with low power consumption comprises a chip main body 1, the model of the chip main body is MSP430FR6972, the chip main body is connected to an MBUS bus 2, the MBUS bus is connected to the wired remote water meter, when the device works, the MBUS bus acquires information of a plurality of wired remote water meters, then transmits signals to a comparator 5, and transmits the information to the chip main body from the signals after comparing data stored in the chip main body. The chip main part still connects in boost module 3, and boost module connects in the MBUS bus, and boost module still connects in first battery power module 8, and first battery power module is 7.2V battery, and boost module is provided with two, steps up 36V and 24V with the 7.2V that the battery provided respectively for MBUS bus work needs, when the boost module that the chip main part was controlled is out of work, the power consumptive 0 that is of this module. The chip main body is further connected to a second battery power supply module 7 which is a 3.6V battery, the second battery power supply module is further connected to a communication module 6, and the communication module is connected to the chip main body. When the 3.6V battery controlled by the chip main body supplies power to work, the communication module supplies power to complete the communication function with the server end; when the 3.6V battery controlled by the chip main body supplies power and does not work, the power consumption of the communication module is 0.
