The English name of content couplet net is “Internet Of Things” , just as its name implies, it is the network ” that “ thing other people is linked together, it will have the object photograph of ability of perception, communication to join, communication and information are exchanged between implementation thing other people. Every day object acquired new life because of join, they will have study capacity even, the through feeling the behavior of the user behavior to oneself make corresponding adjustment.

 

Times of content couplet net, numerous enterprise undertakes to traditional product intelligence is changed transform. Join forces is science and technology dedicated all the time at electric energy metric domain, offer electric energy to feel the solution of ability for intelligent electric equipment, the HLW8012 ／ HLW8032 that rolls out before has minor volume, periphery the advantage such as simple, high reliability, apply extensively already at intelligent electrical outlet, charge the domain such as street lamp of picket, intelligence. Roll out 2 new-style electric energy again today metric chip HLW8112, HLW8110, more promotion had in respect of function, function.

 

 

Traditional electric energy is metric HLW8032 of chip HLW8012 ／ , measurable 1 voltage, electric current, power, n, metric chip can measure new-style electric energy more comprehensive electric energy parameter, precision is taller.

1, protection of leakage of electricity

 

After home appliance product is being used for a long time, as ageing of parts of an apparatus, meeting occurrence power consumption increases, even leakage of electricity, cause safe hidden trouble. HLW8112 increases 1 electric current to detect on only channel foundation the passageway is used at detecting state of equipment leakage of electricity. In the graph 2 in, b passageway undertakes to laden equipment through voltaic transformer leakage of electricity detects, when laden equipment produces leakage of electricity, HLW8112 brings crural output to cut off facility power source quickly through INT2, protect security of the person that electric equipment is used.

 

2, overload protection

 

Home appliance is in use process, because use undeserved or ageing of parts of an apparatus, may appear excess load of working electric current, power, time grows, may damage home appliance, cause fire. HLW8112, HLW8110 interior can install maximum of electric current, voltage, power, should detect when overload is unusual, chip undertakes updating demonstrative to corresponding register. HLW8112 still can be configured be opposite to cite a base through INT1 overload is unusual undertake demonstrative, answer more seasonable than HLW8110.

 

3, avoid calibration

 

HLW8112, HLW8110 oneself measures error control to be in 2 ％ less than, if resistor of sampling of electric current, voltage uses 1 ％ taller perhaps, overall measure an error to be able to be controlled control in 3 ％ , if had accorded with the norms requirement of the product, can avoid all calibration, save cost of a lot of facility cost, labour cost, time.

 

If afore-mentioned errors cannot achieve the norms requirement of the product, can regard independent module as metric module, undertake module calibration, calibration data can protect existence HLW8112, in HLW8110, direct will metric module is received from the back overall in can, avoided overall calibration.

 

4, over- 0 detect

 

Over- 0 detect the function can control switch circumstance to offer the more efficient, safer control that use phone for PWM. HLW8112, HLW8110 has signal of electric current, voltage to pass 0 detect function, still can have configured 0 means through register, interior detects the result updates corresponding register. HLW8112 can be configured had been opposite to cite a base through INT1 0 detect the result undertakes demonstrative, answer more seasonable than HLW8110.

 

5, 2 passageways are measured

 

Intelligent electrical outlet divides weak opening electrical outlet and poriferous platoon to insert, every insert Kong Dou to must have a metric module, yuan of parts of an apparatus that so the poriferous platoon before inserts metric module much, volume is larger, take up the interface resource of MCU is more. HLW8112 can measure 2 1 2 electric current, voltage, power, n at the same time, a metric module can realize 2 measurement that insert aperture, contractible bulk, reduce cost.

6, wisdom uses phone

 

HLW8112, HLW8110 still can measure the electric energy parameter such as frequency of element of voltage pelter, power, line, peak value, photo corner, power of virtual value of integrated electric current, voltage, have rendered great service, inspect parameter waits in power, can build complete electric equipment to run condition model. For instance: According to power element, power reason of breakdown of the ageing circumstance of unusual judgement electric equipment, electric equipment; Occurrence voltage pelter, peak value is too great or when the state with line frequency bigger change, adjust the working position of electric equipment appropriately, make electric equipment is in safety to use from beginning to end report, efficient the condition that use phone.

 

Join forces devotes oneself to to popularize Meter IC to be in all the time for science and technology home appliance of intelligent household, intelligence and the application that wait for energy-saving product to go up related to “ report ” and solution, the HLW8032 that HLW8012 of pulse output metric chip and UART string together an output is used extensively all the time wait for product of content couplet network to go up at street lamp of WIFI electrical outlet, intelligence. Roll out this have leakage of electricity to detect the function is metric chip HLW8112, want excel HLW8012 and HLW8032 on function index, use setting is more extensive, can apply at equipment of intelligent home appliance, leakage of electricity to detect illume of electrical outlet of equipment, metric ammeter, WIFI, LED and charge picket domain. HLW8110 is the metric chip of a 8PIN, be HLW8112 simplify edition, it only 1 voltage is measured and 1 electric current is measured, inside buy brilliant brace up, use UART communication means, special agree with mould volume is minor lesser product development, for instance WIFI electrical outlet is mixed on the product such as PDU.
