Description

Intelligent electric meter based on uCOS operating system

Technical field

The present invention relates to a kind of intelligent electric meter, relate in particular to a kind of intelligent electric meter based on uCOS real time operating system.

Background technology

At present, the software systems of intelligent electric meter are all used the bare machine program of moving a master routine, the intelligent electric meter program structure of this kind of framework is complicated, real-time is not strong, poor stability, and the function that later development is new is also more difficult, often need again to develop, this just causes overlapping development, has reduced development efficiency, has not only extended product development cycle but also has increased cost of development.

Summary of the invention

The object of this invention is to provide that a kind of software system structure is simple, real-time performance is strong, stability is strong and be beneficial to the intelligent electric meter of later stage Function Extension.

In order to achieve the above object, technical scheme of the present invention has been to provide a kind of intelligent electric meter based on uCOS operating system, comprises central processor unit, central processor unit respectively with electric quantity acquisition module, display module, outer memory module, RTC real-time clock module, load module and communication module are connected, and by power module, are central processor unit, electric quantity acquisition module, display module, outer memory module, RTC real-time clock module, load module and communication module provide working power, and electric quantity acquisition module connects respectively current sensor and voltage sensor, it is characterized in that: on central processor unit, move uCOS real time operating system, by the electric quantity acquisition module corresponding to hardware, display module, outer memory module, RTC real-time clock module, load module and communication module are divided into corresponding electric quantity acquisition task, electric weight Processing tasks, incoming task, demonstration task, output task and MODBUS communication task, uCOS coordinates by message queue and semaphore and synchronizes various tasks.

Preferably, then voltage parameter, current parameters and the current waveform data that obtained by current sensor module and voltage sensor module by electric quantity acquisition module are stored into corresponding register after calculating the electric energy of voltage effective value, current effective value, power, frequency, power factor (PF), phasing degree and consumption.Electric quantity acquisition task is by reading the corresponding register of electric quantity acquisition module by voltage effective value, current effective value, power, frequency, power factor (PF), the data such as electric energy of phasing degree and consumption are read in central processor unit, the data that electric weight Processing tasks is used corresponding algorithm process electric quantity acquisition task to obtain, then generate and show data, alert data and communication data, electric weight Processing tasks judges whether to generate according to the alert data generating reports to the police to drive alarm output module, alarm output module is connected with central processor unit, by demonstration task, will show that data show by display module, effect by MODBUS task is by MODBUS communication protocol and other devices communicatings and sends communication data.

Due to uCOS operating system be through strict test can be for the real time operating system of spacecraft, so its stability is strong, security performance is high, real-time is good.For the Function Extension in later stage, just increase the task of corresponding function, like this construction cycle short, software systems reusability is high, shortens the cycle of launch simultaneously, significantly reduces R&D costs.

The invention has the beneficial effects as follows: stability is strong, security performance is high, real-time is good, system extension is easy, can shorten the cycle of launch, significantly reduce R&D costs.
