Structural principle

Main structure：

The flame-retardant ABS shell is adopted, which is firm, sealed and shielded.

ABS shell can ensure the stability and safety of product operation：

The instrument plastic shell made of ABS material has excellent impact strength in terms of mechanical properties. It can be used at extremely low temperature. Even if the ABS product is damaged, it can only be tensile damage rather than impact damage. The ABS has excellent wear resistance, good dimensional stability and oil resistance. It can be used for bearing under medium load and speed. The creep property of ABS is larger than PSF and PC, but smaller than PA and POM. ABS The bending strength and compression strength of ABS are poor in plastics. The mechanical properties of ABS are greatly affected by temperature.

The appearance of ABS is an opaque, ivory colored, non-toxic, tasteless, low water absorption product. It can be applied to various colors and has a high gloss of 90. The relative density of ABS is 105abs, which has good combination with other materials. The coating is easy to be printed on the surface. The oxygen index of ABS is 182, which is a flammable polymer. The flame is yellow, with black smoke burning, but does not drip, and gives out a special smell of meat.

ABS is a kind of resin with good comprehensive properties. It has higher impact strength and surface hardness in a wide range of temperature. The temperature of thermal deformation is higher than that of PAPVC. The shrinkage rate of ABS with good dimensional stability is in the range of 04-08. If it is strengthened by glass fiber, it can be reduced to 02-04 and the critical surface tension of ABS after plastic shrinkage is 3438mncm

Why is the Prepaid Electric Power Meter more accurate? This is determined by the different structure of the electronic watch and the mechanical watch. The mechanical wear caused by the rotation and the mechanical deformation caused by the vibration of the mechanical watch are easy to cause the error out of tolerance.

Unlike mechanical watches, which have turntables and no mechanical wear, electronic watches have better error characteristics. The error curve from light load to maximum load is basically straight, easier to control error, and higher accuracy than mechanical watches. If you don't believe it, you can do the experiment yourself.

If you don't have any leakage problem at home, turn off the main switch of the electricity meter, the pulse light on the intelligent electricity meter will not flash, but the number on the electricity meter is still displayed. Don't worry, flash is not a kilowatt hour!

The pulse light on the smart meter flashes to indicate that the line is loaded. The flicker frequency of pulse lamp varies with the power load. The larger the power load is, the faster the flicker is.

1. Anti stealing function realizes the anti stealing function through the technology of double circuit metering, double circuit power-off (single phase), time recording, magnetic field detection, cover opening detection, etc.

   
   

2.Data remote transmission function realizes the combination of microcomputer technology, digital communication technology and instrument measurement technology, integrates measurement, data collection, data transmission and data processing, comprehensively processes the user's electricity information, and realizes the remote meter reading function through signal output. This function can eliminate the problems of power misreading, misreading, missing reading and not reading the meter in time.

3.Automatic switch on / off function the intelligent meter can realize the remote control of the analog switch in the meter through the setting of the power consumption management software, so as to achieve the power cut-off function.

4.The multi rate function can realize time-sharing billing, different time periods, holidays or different monthly electricity consumption charging according to different prices by setting the system software and terminal software.

5.Query function supports mobile phone online query at any time, such as electricity fee, historical electricity consumption, real-time electricity price, etc., to understand the electricity consumption of your home at different times, and to be a prudent electricity user.

6.The data storage and backup function of the smart meter adopts a special memory chip, and adopts a number of data storage measures. Once one or several data is abnormal or lost, it can be corrected and restored by other places.

7.Anti cheating function adopts authorized password operation, and has operation log, which can record the operation process in detail to prevent malicious operation or cheating.

In essence, electric energy collection is nothing more than voltage and current collection, so there must be a / D conversion part to sample analog signals into digital signals, and then calculate and analyze the electric energy data through the single-chip computer in the table, and then cache the data into the cache chip, the user can read through the corresponding interface and protocol. It doesn't matter what way remote transmission is used. Infrared, wired, wireless, GPRS, Ethernet, whatever you like,

 you'll be happy. Because the Prepaid Electric Power Meter will help you more.
