Below in conjunction with Fig. 2 workflow of the present invention is further described.
At first, system carries out self check, after self check is finished, records the self check information of this startup, if having unusually, produces alarm event.
Secondly, start monitoring and answer process, after watchdog routine started normally, after 2 main business processes of the application process of starter gear and multimedia process, application process was followed successively by each functional module and starts a processing threads.This device has 10 threads such as ether communication thread, wireless module communication thread, usb communication thread, AC sampling thread, GUI thread, and cross-thread carries out data sharing by shared buffer memory or database.Monitoring process is responsible for the operation maintenance of subprocess.
Read separately the correlation parameter of thread function in each thread, comprise the parameters such as each communication module parameter, the parameter of checking meter, control parameter, AC sampling calibrating parameters, analog quantity calibrating parameters, stipulations protocol parameter, 2 grades of cryptographic parameter, encrypting module parameter, liquid crystal display parameter, and the parameter that reads carried out validity check, if parameter for subsequent use is enabled in the validity check failure automatically.With parameter each module correlation function is carried out initialization after reading end.
Again, data base initialize, CPU (central processing unit) 1 is recovered the last statistics that obtains and the running state data of consumer, electricity consumption data etc., the zero clearing of device real time data.
So far, device starts end.
Then, liquid crystal display enters the first screen, and backlight is lighted, synchronous display system time, running status; Show user's EFR STK commonly used, and wait for user's operation, if there was not operational order in 3 minutes, backlight closing, and close demonstration, wait for that the user triggers demonstration.
The below's minute different threads is introduced the operational process of device.
Concurrent execution Energy Efficiency Analysis thread in this thread, according to user configured measurement point parameter, always add group parameter and time cycle parameter, carries out Energy Efficiency Analysis to the electric terminal that meets this parameter.Can be arranged to monthly and per year analyze, the concrete analysis process is as follows:
The electricity consumption coulometric analysis: according to the data-frozen that density is carried out each measuring point that freezes that arranges, minimum freeze-off time is 1 hour, and freezing data was preserved 3 years, and the user carries out statistical study over according to the moon, can draw and obtain time span for being 1 year electricity consumption curve; Per diem statistical study can obtain time span and be 1 month electricity consumption curve, and is identical, add up by the hour, can obtain time span and be 1 day electricity consumption curve and can draw which month, day, the period is peak of power consumption, which month, day, the period is low power consumption, thereby provides the rational utilization of electricity suggestion.
Energy Efficiency Analysis: same, running state data in conjunction with consumer, or the operational factor by circuit, in historical freezing data storehouse, take out active power and the power factor of the time period circuit out of service of the consumer that needs analysis, the numerical value of section compares with working time, if the power factor impact on circuit during operation is large, is the large equipment of energy consumption with this device flag.Can be per diem, week, month, year carry out sort method, transform thereby guides user is energy-saving and cost-reducing.
Concurrent execution exchanges the data sampling conversion, sends into statistical module and adds up, and storage unit regularly takes data to store from statistical module, puts into corresponding database.
The concurrent execution thread of checking meter after meter reading data is changed, is sent into statistical module and is added up, and storage unit regularly takes data to store from statistical module, puts into corresponding database.
Concurrent execution radio communication thread, the data interaction of this device and control center, and movement is subjected to device data mutual.
Concurrent execution ethernet communication thread, treating apparatus and Ethernet equipment data are mutual.
Concurrent execution micropower wireless security protection thread adds the data that obtain in the corresponding device databases to, and warning information outputs to the alarm output interface synchronously in liquid crystal display.
Concurrent execution load management thread, power definite value control are according to the data analysis to sampling, if power factor is lower than a threshold value or power greater than certain limit value, and power supply that will the excision corresponding device, and prompt alarm information.Reach the arrearage thresholding, prompting and alarm output detect the consumer fault, say the word to consumer or directly excise this consumer, out of service and outputting alarm, alarm can also send on the mobile phone of specifying the recipient by the configuration short message mode, and can configure 10 numbers.This thread is also processed the switch amount signal.
Concurrent execution remote upgrade thread possesses the breakpoint transmission function, if possess the remote upgrade server, and device arranges and allow the automatic remote function, when detecting new edition upgrading, can automatically carry out remote upgrade.Also can passive remote upgrade.
Concurrent execution GUI man-machine interface thread can be made amendment to some customer parameters by the interface, browsing data, and can, derive the data of appointment by USB.But the parameter that has cured before dispatching from the factory is invisible to the user, also can't derive, but can factory reset, but this operation will possess administrator right.
Concurrent execution local communication module after local any communication mode (USB, 232 serial ports) is enabled in setting, just can communicate by related protocol and corresponding device, realizes local upgrade and maintenance.
All data interaction optional data encryption functions, critical data carries out hardware encipher and the software cryptography mode is optional.Support the data encryption algorithm such as DES, RSA, AES, can need to encrypt by configuring the transmission of which data and external unit.
4 threads of concurrent execution terminal media process block, obtain the data of acoustic pickup and camera, encoded cell encoding, convert respectively mpeg 3 and MPEG4 form to, send communication unit to transmit, also will after the audio frequency of exporting, video data send decoding unit decodes, drive loudspeaker output and deliver to liquid crystal display simultaneously, also can select TV-OUT to output to other video display apparatus.
In sum, the present invention carries out the voltage and current data acquisition by the 2 pairs of consumers in AC sampling unit, and send data to CPU (central processing unit) 1 computing, thus obtain user's power consumption, realize power consumption monitoring and the energy consumption analysis of larger power user; Simultaneously, by the mutual swap data in telecommunication unit and main website, realize Centralized Monitoring and the management of equipment.
