Below are: data storage module and display module of the work flow is as follows: CS5460A according to enter the sampling circuit voltage, current computing power from the internal functions calculate the power, and type of deposit in the corresponding register, and then the voltage and current measurements, such as Transmitted to the CPU, CPU adopted by the voltage, current value of the power to the actual value of each mining End put a sampling of storage, and storage sampling value of the unit value of each sample were cumulative, will be sent to the data 8 LED digital display of a static real-time, the two previous shows that the code users, showed that after six users, the whole number and decimal degrees.The process of storing data we use the chip 24 C16, 24C16 is CMOS 16384-bit serial E2PROM, can read and write, 1012, the internal data can save 100 years. Communications interface module adopted the RS-485 bus standard. RS-485 is based on the differential signal transmission of the serial communication link layer protocol. It resolved the RS-232 transmission distance too close to an agreement (15 m) of the defect, is widely used in industry on the longer distance data communications link layer protocol. In this system, transmission distance is greater than 15 m, then RS-232 can not be used, and the use of Modem also uneconomical, the choice of RS-485 serial communication interface standards, according to RS-485 standard, data transfer speeds up to 100 kbit / s When communication range of up to 1200 m,Basically in line with the design requirements. RS485 bus station for interconnection is very convenient, with a twisted pair to achieve, as a balance to send and receive difference, with a total anti-interference capability. Taking into account the far distance, the status of various kinds of interference, we have adopted this design easy to implement segregation of 75 LBC184 photoelectric chips transfer data.

Data modules and memory modules work processes are as follows: CS5460A according to enter the sampling circuit voltage, current computing power from the internal functions calculate the power, and type of deposit in the corresponding register, and then the voltage and current measurements, such as transmitted to the CPU , CPU adopted by the voltage, current value of the power to the actual value of each mining End put a sampling of storage, and storage sampling value of the unit value of each sample were accumulated, the data sent to the eight LED Real-time digital of a static display, the top two shows that the code users, showed that after six users, the whole number and decimal degrees. The process of storing data we use the chip 24 C16, 24C16 is CMOS 16384-bit serial E2PROM, can read and write, 1012, the internal data can save 100 years.

In the design of software to solve the main problem is the CS5460 initialization, the relevant register allocation and the acquisition of the electric energy. CS5460 which registers are 24 long, through reading and writing these registers, we can achieve the voltage, current, power, power, and so the measurement; power into the acquisition of the Youxi voltage, current and the method of calculating the energy, paper has been A detailed analysis.
Taking into account the environment in the application of the existence of interference on the impact of Meter, the last major discussed the causes of interference, jamming the system of hardware and software and anti-jamming measures. In this paper, the anti-jamming design of hardware and software design anti-jamming were introduced, anti-interference in hardware design, the first of the source of interference and interference characteristics of an analysis and response to these features, take a variety of reliable measures. In addition to hardware anti-jamming measures, has also taken several measures to improve the anti-jamming software system reliability.
Owing to the time constraints and conditions, the system there are still some problems to be solved, such as paper display module used in the design of LED power consumption, shows that small amount of information, short life, can use to replace the LCD liquid crystal display; Communications port, just done a theoretical study, has not applied to
