Brief description
Fig. 1 is the circuit block diagram of embodiment.
Specific embodiment
As shown in figure 1, the present embodiment is a kind of Internet of Things flow volume correction instrument, including micro-control unit 1, this microcontroller
Unit electrical connection memory element 2, GPRS communication unit 3, valve controling circuit 6, voice alarm circuit 7, pressure transducer 14,
Temperature sensor 15 and RS458 communicating circuit 17, in the present embodiment, above-mentioned components and parts are powered by set of cells 8.
Because GPRS communicates, consumption electricity is larger, and in the present embodiment, GPRS communication unit 3 also adopts external direct current power supply 11
Power for it, GPRS communication unit 3 is connected with set of cells 8 and external direct current power supply 11 through many power selection circuits 13, many power supplys
Selection circuit 13 is electrically connected with micro-control unit 1, by micro-control unit 1 control many power selection circuits 13 select set of cells 8 with
GPRS communication unit 3 is energized or external direct current power supply 11 is energized with GPRS communication unit 3.
The present embodiment set of cells 8 electrically connects micro-control unit 1, external direct current power supply 11 warp through battery voltage sampling circuit 9
DC voltage sample circuit 12 electrically connects micro-control unit 1.Micro-control unit 1 passes through battery voltage sampling circuit 9 sampling battery
The voltage of group 8, and in set of cells 8 not enough power supply, warning is sent by voice alarm circuit 7;By DC voltage sample circuit
12 sampling external direct current power supply 11 voltages, and pass through in external direct current power supply 11 undertension to control many power selection circuits 13
Switching set of cells 8 is powered for GPRS communication unit 3.
Under conditions of outer being electrically accessed, because GPRS communicates, consumption electricity is larger, and table end does not support that GPRS exists in real time
Line function, master station communication server can not be communicated with table end at any time and carry out data exchange, but can arrange interval data to table end
Upload function, such as every month upload several times, and number of times can not be excessive, in order to avoid set of cells 8 has quickly consumed.The condition being electrically accessed outside
Under, GPRS interface enables automatically, table end meeting automated log on main website server kilowatt meter reading-out system, and server can be realized with table end in real time
Communication.When being electrically cut off outward, table end will upload data immediately, notify system table end not connect outer electricity condition.
The operation principle of the present embodiment is as follows:The present embodiment passes through RS458 communicating circuit 17 and the communication of flow base table, obtains
The gas usage information of flow base table collection, combination pressure sensor 14, the temperature and pressure information of temperature sensor 15 collection
Gas usage is modified, and revised consumption information is uploaded to cloud server by GPRS communication unit 3.
Certainly, described above is not limitation of the utility model, and this utility model is also not limited to the example above, this skill
The those of ordinary skill in art field, in the range of this utility model, the change made, changes interpolation or replaces, should belong to this
The protection domain of utility model.
