Description
Technical field
The present invention relates to mathematics model analysis, RS485 and TCP/IP communication network, the SQLSERVER database technical field of parameters of electric power metering, malice load, be specifically related to the electric power meter method for designing being with malice remained capacity.
Background technology
In order to the Electrical Safety of dormitory and student dormitory, prevent fire and threat to life property safety, the automatically controlled management system of intelligent electric meter is all installed in the dormitory of College Students ' Apartments and large enterprise, centralized management, centralized control, by computer, electric power is set, exceed and power auto-breaking is set, even our early stage product can be accomplished to open computer by regular hour difference, the general power of whole computer exceeds setting value not power-off, and the electric furnace, immersion heater etc. of same general power can auto-breakings.
Along with improving constantly of China's rapid development of economy and living standard, student dormitory and dormitory progressively install an air-conditioner, the automatically controlled management system of early stage intelligent electric meter can not adapt to requirement, some employing air-conditioning independent wiring, and adopt special air conditioner socket, the complicated cost of such construction is high, and also have hidden danger, user by removing private jack or inserting common socket by conversion in room, reach and burn electric furnace, use hair dryer, use immersion heater etc. to have the equipment of potential safety hazard, bring very large disaster hidden-trouble still to apartment and dormitory.
Summary of the invention
The object of this invention is to provide the electric power meter method for designing of band malice remained capacity, the electric power meter of the band manufactured by it malice remained capacity has the malice remained capacity function that electric energy metrical and air-conditioning normally use.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: the electric power meter of the band malice remained capacity of manufacture of the present invention comprises CPU administration module, Multifunctional measuring module and power module, CPU administration module and Multifunctional measuring model calling, power module is to CPU administration module and Multifunctional measuring module for power supply.
Described CPU administration module has two serial ports, and a serial ports realizes data acquisition and telecommunication with gateway communication, and a serial ports is with multifunction electric meter module communication, and two communication ports are electric isolution.
Described Multifunctional measuring module is one piece of multifunction electric meter directly do not shown, and is made up of CPU, metering units, ferroelectric memory, 485 communications, power trigger circuit and bistable state Large Copacity magnetic latching relay.
The beneficial effect that has of electric power meter of the band malice remained capacity of the present invention's design:
1, collect the malice remained capacity function that electric energy metrical and air-conditioning normally use, make the loop that installs an air-conditioner can only using air-condition, and use immersion heater etc. to have the high-power electric appliance automatic trip power-off of fire safety evaluating hidden danger;
2, avoid apartment that many loops are installed and increase the unnecessary investment that the equipment such as cable switches cause, even if as long as two-circuit has socket still to have potential safety hazard;
3, power consumption is low especially, and the power consumption of 36 ammeter modules is less than or equal to 4W.
Accompanying drawing illustrates:
Fig. 1 is structured flowchart of the present invention;
Fig. 2 is that (UA, UB, UC, UN provide working power for ammeter, generally adopt 2.5mm for the schematic wiring diagram of user of the present invention
2cable; 1*, 2,2*, n, n* be user's line, according to size of current configuration).
Embodiment
With reference to Fig. 1-2, the electric power meter of the band malice remained capacity of the present invention's design comprises CPU administration module, Multifunctional measuring module and power module, CPU administration module and Multifunctional measuring model calling, power module is to CPU administration module and Multifunctional measuring module for power supply.
The electric power meter principle of work of the band malice remained capacity of the present invention's design:
Every Multifunctional measuring module all can measure the active energy in this loop, electric current, voltage, active power, reactive power, applied power, power factor, the electrical quantitys such as the angle between mains frequency and current/voltage, many the centralized installations of module, managed concentratedly by CPU administration module, 36 family ammeters are only as a node of 485 communication interfaces, considerably increase the load capacity of 485 buses, ammeter consumed power when pilot relay is failure to actuate at 36 families is not more than 2W, when pilot relay action, consumed power is less than 4W, be specially adapted to present conservation-minded society.
Because each metering module is made up of single-phase multifunctional ammeter, carry out data by electrical quantitys such as the active power to loop, applied power, power factors and move towards to analyze, effectively identify malice load; Refrigeration-heating air-conditioner, computer, electric fan, washing machine etc. normally use, and fast, the hair dryer of electric furnace, heat etc. effectively control use, avoid the potential safety hazard in apartment widely, greatly ensure that the security of the lives and property.
Multifunctional measuring module is one piece of multifunction electric meter not having to show, be made up of CPU, metering units, ferroelectric memory, 485 communications, power trigger circuit and bistable state Large Copacity magnetic latching relay, metering module adopts totally digitilized calibration, autostore calibration parameter and same data multiaddress store, error correction differentiates, thus ensureing the reliability of stored parameter, one piece of metering module only needs a little three mouses namely to complete 1-2 minute calibration; All take special measure between the positive supply of each module and place of working, ensure that and do not interfere with each other between multifunction electric meter module.By the data analysis of the variable quantity of the active power to certain hour scope and the variable quantity of applied power, the character of load can be judged accurately, make the actuating of relay whether accurate judgement;
Not consumed power when power trigger circuit and bistable state Large Copacity magnetic latching relay normally run, only at the 0.1S internal consumption power of action, realizes long-rangely forfeiting electricity, pre-payment, malice remained capacity automatically controls power-off and automatically recover power transmission.
CPU administration module is responsible for data acquisition and the optimum configurations of single-phase multifunctional ammeter; centralized control control module forfeit electricity; centralized management electrical energy pulse; there is double-serial port; a serial ports realizes data acquisition and telecommunication with gateway communication; a serial ports is with multifunction electric meter module communication; two communication ports are electric isolution; 485 communication lines have tight lightning protection measures; each communication line all has PTC fast current to protect and the protection of TVS quick voltage, looks site environment if desired at the multistage lightning-protection module of 485 communication lines increases to ground discharge.
The electric power meter of the band malice remained capacity of the present invention's design can not only identify malice load automatically, but also there is active energy metering, integrate and identify and measure, 2-36 the centralized installation of module, little being convenient to of volume is installed, be guide tracked installation when only needing 1 module, and have the production licence that provincial Bureau of Technical Supervision issues.
