Detailed description of the invention
The following is the specific embodiment of the present invention and combine accompanying drawing, technical scheme is further described,
But the present invention is not limited to these embodiments.
Please join Fig. 1, single-phase charge-controlled intelligent electric meter includes expense control module, uses 7816 protocol communications with expense control module
ESAM module；With the CPU card that expense control module uses 7816 protocol communications；The storage mould being connected by memory interface with expense control module
Block；The LCD display module communicated with expense control module employing message-driven and task module.
Above-mentioned 7816 agreements are standard communication protocol, and above-mentioned message-driven communication mode is the embedded pipe of the present invention
The function of the message-driven service module in reason system.
The present invention uses embedded management system to control above-mentioned module so that communication between above-mentioned module is convenient and just
In maintenance.
To this end, refer to Fig. 2, Fig. 3, Fig. 4, the embedded management system of the single-phase charge-controlled intelligent electric meter of the present invention is by three
Layer is constituted, and i.e. drives layer, intermediate layer and application layer.
Driving layer as the bottom of embedded management system, it is used in storage system changing less part.This reality
Execute in example, drive layer to be divided into system configuration module and user configuration module two major parts.
System configuration module includes MCU bottom, including such as NEC0527 chip bottom, Fudan University's micro-FM301 chip bottom
Or U.S.'s letter 71M6542 chip bottom；Also include that each port configures module, hardware configuration module, such as PCB selects, MCU selects,
Computation chip selects, clock chip selects, whether selects carrier wave etc.；Also include that ammeter configures module, such as meter constant, electricity
Traffic specification, voltage specification, starting current gear, metering constant parameter setting, software and hardware version number etc..Additionally, due to interrupt function
Change less, therefore interrupt function is also integrated in by the present embodiment in system configuration.
User's configuration then includes the module that various user can customize, such as task, message and the definition of message parameter,
Beat unit, the definition (including that programming state keeps the number of minutes, password locking to keep the number of minutes etc.) of various delay times, support
Stipulations number, electricity customizes, and take control customization, record customization, freezes to customize, various compare service customization etc..User configures mould
Block also includes other expansion modules that can customize.
Said system configuration and user's configuration are all to change less part in the future, are detached out and are easy to follow-up dimension
Protect and software upgrading.
Intermediate layer completes various services and the message transmission of task needed for providing application layer.Every configuration in intermediate layer
It is the core place of the present invention, has had the configuration in intermediate layer just can make each task functional module of application layer can be only just
Erect put, complementary interference.Concrete, intermediate layer includes: metering service module, is used for providing computation chip driving, coulant meter
Amount service, electric current, power factor (PF) etc. compare service function；LED shows service module, be used for providing various display chip to drive and
Display resolves interface function；Clock service, is used for providing system clock service function；Communication service module, for providing such as
Infrared communication, 485 communications, carrier communication service；Storage services module, be used for providing memory block division, memory block read/write function,
Senior read/write function etc. service；Drive service module, be used for providing all kinds of IIC, RSIO, SPI, ESAM etc. to drive；Record and freeze
Knot drives service module, for providing all records, freezing use unified searching and increase function and public function service
Module.
Even more important, the intermediate layer of the present invention is also provided with beat service module, is used for judging each task in application layer
Whether the fixing execution time arrives.Being also provided with message-driven service module, in application layer, the message between each task passes
Pass.Each task module in application layer determines the execution state of task according to the message that message-driven service module transmits.Example
Time delay performs or interrupts execution etc. in this way.
Concrete, can be found in Fig. 3, each task module in application layer is according to the function realized needed for intelligent electric energy meter,
The task module of the independent operating of design forming is divided according to different running frequencies, different functions.
Those task modules run in the major cycle of backstage, and each task module order is run, and does not has the concept of priority.
The circular order of those task modules is determined by beat service module.I.e. beat service module has judged a certain task module the most
To its fixing execution time in the major cycle of backstage.
Those task modules all have the message queue of oneself, can receive the message sent from message-driven service module
Or the message that interrupt module sends.Task module takes out message from message queue and then realizes the function of message queue.
So so that those task modules are functionally independent of one another, upon execution, via message-driven service module
Message transmission function is the most associated with each other.So that when conveniently making change at device, interface circuit or functional requirement etc.,
Have only to revise corresponding service module with task module without affecting the working stability of other service modules and task module
Property.
In the present embodiment, each task module of application layer includes: ammeter stipulations communication task module, rate calculate task mould
Block；Message pool task module, for being sent to corresponding task module by the message deriving from interruption；System beat task mould
Block, is used for safeguarding system beat source and calling beat service function；System service task module, is used for each task of the system that initializes
And confirm that power supply is the most normal；Power failure task module, is used for terminating each task module and entering low-power consumption mode；Account day appoints
Business module, is used for calling account day function；Take control task module, take control function for every；Metering tasks module, is used for measuring
The timing detection of parameter, the reading of ammeter real time data, the execution of electric quantity function and the execution of comparision of quantity of electricity function；Clock task
Module, for regularly calling clock service function and monitoring Multifunctional mouth characteristic change；Freeze task module, for regularly freezing
Tie, freeze day to freeze with integral point；Logger task module, for programmed recording and record of uncapping；MCU mouth line and depositor are safeguarded and are appointed
Business module, when each systemic circulation, detect mouth line and buffer status, and unified management mouth line and the direction of depositor and
Low and high level；Ammeter display task module, for performing the configuration of display task and explicit function；AD sampling task module, uses
In detecting cell voltage according to beat；Rate electricity price, step price switching task module, at rate electricity price and step price
Middle switching.
According to the actual requirements, other task modules can also be increased in application layer.
Specific embodiment described herein is only to present invention spirit explanation for example.Technology neck belonging to the present invention
Described specific embodiment can be made various amendment or supplements or use similar mode to replace by the technical staff in territory
Generation, but without departing from the spirit of the present invention or surmount scope defined in appended claims.
