Below the software design of above-mentioned intelligent electric meter is described in detail, is main program flow chart with reference to Figure 13, Figure 13.
Software uses modularization programming thought, writes corresponding driver for each hardware cell, and each driver is separate,
Realize calling linking by mastery routine.After intelligent electric meter powers on, STM32 main control chip starts to perform mastery routine.Mastery routine is first
Each functional interface program and driver are initialized, initialized laggard enter main circulating program.In main circulating program,
STM32 identifies the communication module accessing ammeter the most automatically, and combines mode of operation and automatically select corresponding communication plan, afterwards
Start to gather ADE7880 metering module data, and store after the data gathered are processed.Then by calling system clock
One action mode flags position is read, if ammeter is set to harvester pattern, then according to logical at interval of a period of time (such as 15min)
Letter scheme performs to gather the program of other ammeter datas.Last start-up study programs etc. are to be interrupted, and delay procedure returns after having performed
Continue executing with identification ammeter communication module program to main circulating program starting point, go round and begin again.
In software design, interrupt main point three kinds: external interrupt, timer interruption and serial ports interrupt.External interrupt is by counting
Amount module produces and carries out affair alarm；2ms timer interruption uses for receiving carrier module data, when ammeter COM1 is not inserted
When entering carrier communication module, this interruption does not starts；Serial ports interrupts being received data by infrared, RS485, Wi-Fi, GPRS communication module
Time produce, each module uses serial ports to interrupt.When program initialization, each interruption need to be arranged preempting priority and response
Priority, to determine the sequencing that each interrupt service routine performs, the interruption that preempting priority is higher can interrupt holds
The interrupt service routine that capable priority is relatively low, the interruption that response priority is higher is preferentially held when several interruptions produce simultaneously
OK.
Communication plan to above-mentioned intelligent electric meter selects to be described in detail below, is communication plan with reference to Figure 14, Figure 14
Select flow chart.After STM32 completes program initialization, first automatically scan each communication interface, identify the communication mould inserting ammeter
Block, reexamines ammeter mode of operation flag bit and differentiates the mode of operation set by ammeter.If common intelligent electric meter pattern, then certainly
Dynamic all communication modules are set only do passive response, i.e. only send phase according to harvester, concentrator or the main website instruction of upper level
Answer data, the most actively send query statement；If harvester pattern then needs to select corresponding communication according to the communication module inserted
Scheme.Power line carrier, PLC communicates as telecommunication mode with GPRS, and intelligent electric meter and harvester are impossible in actual applications
Use both communication modes simultaneously, therefore can produce communication plan one and communication plan according to the access of both communication modules
Four.When ammeter communication interface is not inserted into power carrier and GPRS communication module, ammeter program will carry out other two kinds of communication parties
The differentiation of formula, first checks for whether Wi-Fi module connects public network, if being not connected with public network or being not inserted into Wi-Fi module, selects to lead to
Letter scheme two, if having connected public network, selects communication plan three.
In intelligent electric meter software design, the interface routine of each communication module is separate, and the plug of each communication module is equal
The function of other modules and program will not be impacted.In mastery routine, often performing an accounting procedure all can run-down
Communication interface, to guarantee that communication module program after changing, removing or add timely automated can adjust corresponding communication plan.
In sum, the modules of the intelligent electric meter that the embodiment of the present application provides is separate, and each functional module is equal
Detachably, replaceable, can select according to the actual requirements to use, and can have five kinds of selective combinations of communication mode, have very
Communication function flexibly, also has the function of harvester concurrently, can omit harvester in actual installation, reduces cost.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
