IntroductionThe application of communication power source centralized monitoring technology in communication power supply indicates that the maintenance and management of communication power supply is changing from manual management mode to machine mode. The following is its purposes: (1) adapt to the development of communication technology; improve the maintenance and management of communication power supply equipment.(2)improve the power supply quality of communication power supply, making the power supply system have higher reliability and economy.(3) take full advantage of the computer technology to make the management of power supply equipment more automatic and intelligent.(4) realize less manual work of communication power supply equipment monitoring.(5) improve the maintenance efficiency and reduce maintenance costs. At present, the development of communication power centralized monitoring technology and the implementation of the monitoring system have entered a new era.As for function, in order to meet the requirement of machine monitoring than manual work, it emphasizes the quick response and fault alarm accuracy to the fault events of the power equipment. At present, the power supply monitoring system is continuously improved and developed based on its basic functions, such as telecontrol, teleindication and telemetering, monitoring information query, data storage and recording, real-time historical trend, system configuration, remote operation, password management, support for networking, etc. 1. Intelligent Device AccessBecause there are many kinds of communication power supply equipment, for intelligent equipment, even the same kind of equipment also have different protocols because of different manufacturers, in addition, there are many suppliers of power supply equipment, thus there are more kinds of protocols. In the process of implementation of the monitoring system, to make better use of the resources of intelligent equipment, the intelligent device is directly connected to its monitoring system through the conversion of the communication interface and protocol. The communication interface conversion basically belongs to the hardware conversion between RS-232, RS-485 and CAN, which is easy to realize. In the past, the conversion of communication protocols has always been a thorny problem in the implementation of monitoring systems. At present, this problem has been preliminarily resolved. On the one hand, most power supply equipment manufacturers can provide the communication protocol of their equipment actively, on the other hand, the intelligent equipment receives agreement officially. Both of them make the protocol conversion easily. At present, if the protocol and communication interface conversion is based on protocol converter, this method is connecting a protocol converter between an intelligent device and station monitoring host. One end is connected with the serial port of the intelligent device, another is connected with the serial port of the station monitoring host computer, thus the conversion of communication protocol and the communication interface is completed.In short, the protocol converter is a microcomputer system with CPU, EPROM, RAM, serial communication port and so on. The protocol conversion generally has two conditions: firstly, there are at least two serial ports which match with the serial ports of the converted intelligent device and the local station monitoring sovereignty respectively; secondly, the conversion software is solidified in the EPROM of the protocol conversion when the communication protocol of the intelligent device is converted into the host protocol of the local station monitoring. This method is more effective for multiple intelligent devices with different protocols connected to one monitoring host at the same time. Another way is putting the protocol conversion function in the station monitoring host, this method is not often used in practice because it is only suitable for connecting intelligent devices with a single subject protocol to a monitoring host. If there are too many kinds of protocols in a monitoring host, the monitoring host will be overburdened and its normal work will be affected. At the same time, it will bring about problems for the development of to monitoring host software. In addition, the unified communication protocol provides a better solution for intelligent device access. 2. Reliability of the Monitoring SystemAs a result of new-technology and high-quality devices are more widely used in the production of communication power supply equipment, the reliability and automation of the monitoring system have been greatly improved. For example, switching power supply equipment, UPS, diesel generator sets and other intelligent devices, as well as non-intelligent devices such as VRLA storage batteries which are widely used now. All have high reliability to improve the monitoring management and provide better conditions for the purpose of less manual work. Therefore, based on the continuous improvement of the performance of the power supply monitoring system, the reliability of the monitoring system should be improved. 3. Perfecting the Self-checking Function of the Monitoring SystemIn order to make the monitoring system play its role more effectively, it is necessary to continuously improve the basic functions of the monitoring system, meanwhile, pay attention to the use of the advantages of computer data processing, developing and improving the high intelligent performance. Fundamentally change the traditional maintenance mode, using the monitoring technology effectively.The implementation of the monitoring system is based on the new maintenance mode. That is, taking the region as the monitoring management center to monitor and manage the corresponding stations and stations. Urban monitoring and management center unifies its regions and manages them. The difference between the manual and mechanized management modes except for the maintenance, the greater difference is computer realize the automatically real-time monitoring. For example, when the power supply equipment fails, The monitoring system will make a quick response and timely report to the corresponding management center. To adapt to this kind of computer monitoring and management mode, it is necessary to change the traditional maintenance mode fundamentally. Using the computer monitoring system, which is characterized by the real-time monitoring of the power supply equipment, but it requires to read the meter at intervals within the period of time, which is stored and printed in the form of a daily report form. These statements should also be kept for two to three years. This method takes up the large resources of the monitoring system, and the data is rarely used in practice. In the face of these problems, the monitoring system in certain functions should be reconsidered:(1) On the basis of continuously improving the reliability of the controlled equipment (power supply equipment), the safety and reliability of the monitoring system can be improved comprehensively.(2) From the overall consideration of the controlled equipment and the monitoring system, since the security and reliability of the power supply equipment can be basically guaranteed (the reliability requirements of power supply equipment are: switching rectifier MTBF> 50,000h, VRLA battery MTBF> 350,000h. the reliability index of AC/DC distribution equipment is higher as required, and the reliability index of the monitoring system should be MTBF> 100000h), the implementation of the monitoring system should be simplified, practical and highly intelligent. At the same time, it should ensure the accuracy and rapidity of the alarm and warning performance of the monitoring system, also with the intelligent optimization of statistical analysis. The continuous improvement of the function makes the reading meter within time period become less significant.(3) renew the traditional maintenance concept and establish a new maintenance system.Therefore, another important task of the future monitoring system is to fundamentally change the traditional maintenance mode. Making more effective use of monitoring technology to impel the power monitoring system play a greater role in the management of communication power supply maintenance. 4. Network Access Detection of the Monitoring SystemTesting the monitoring system is difficult and will be limited by the following conditions:(1) to carry out the inspection of the monitoring system, it is necessary to have a standard basis for the items, indicators, conditions, and methods. And there are some technical requirements of the monitoring system at present, but as the standard basis of monitoring system detection is far from enough.(2) compared with the general power supply equipment, the monitoring system adopts more computer technology, and emphasizes the network and function of the system, and the real time of the system software, so it is difficult to evaluate the technical performance of monitoring system.(3) A monitoring system is a large real-time network system, which has certain capacity features (including software and hardware capacity). The realization of various performance indicators is meaningful only when the capacity is full, but it is impossible to establish a full capacity system when having these detecting indices.(4) restricted by the mode of communication, communication conditions and other aspects. ConclusionFrom the above situation, we can see that the implementation of the monitoring system is indeed facing great difficulties. Even that, the monitoring system is tested through certain methods to reach the maximum approximation. It is necessary and meaningful to describe and evaluate the performance index of the monitoring system.You May Also LikeList of Basic Electronic ComponentsSwitching Power Supply Tutorial: 4V～16VWhat is A MCU’s internal Structure: Single Chip Micro-ComputerPCB Wring Tutorial: A/D converterDIY Community: Let's Make MonitoringHydroponic Grenhouse Monitoring and Control System

The LED outputs of the LM3914 are TTL and CMOS compatible, making it versatile for various digital applications.DescriptionIn the circuit diagram, LEDs D1 to D10 display the battery level in either dot or bar graph mode. Resistor R4, connected between pins 6 and 7 and ground, controls the brightness of the LEDs. The typical value for R4 is between 1kΩ to 10kΩ, depending on the desired LED brightness and current consumption. Resistors R1 and potentiometer R2 form a voltage divider network, and POT R2 can be used for precise calibration of the voltage thresholds.The circuit shown here is designed to monitor voltage levels between 10.5V and 15V DC, making it ideal for 12V lead-acid or lithium-ion battery systems. The calibration procedure is as follows: After assembling the circuit, connect a stable 12V DC source to the input. Adjust the 10K potentiometer (R2) until LED10 glows (in dot mode) or all LEDs up to LED10 illuminate (in bar mode). Now decrease the voltage in steps, and at 10.5 volts, only LED1 should glow. Switch S1 selects between dot mode and bar graph mode. When S1 is closed, pin 9 of the IC connects to the positive supply, enabling bar graph mode. When switch S1 is open, pin 9 disconnects from the positive supply, and the display operates in dot mode.With minor modifications, the circuit can monitor other voltage ranges. To adapt the circuit, remove resistor R3 and connect the upper level voltage to the input. Adjust potentiometer R2 until LED10 glows (in dot mode). Remove the upper voltage level and connect the lower voltage level to the input. Install a high-value potentiometer (such as 500kΩ) in place of R3 and adjust it until only LED1 glows. Remove the potentiometer, measure its resistance, and install a fixed resistor of the same value in place of R3. Your customized voltage level monitor is now ready.Circuit Diagram of Battery Level Indicator Using LM3914Cascading Two LM3914 ICsTwo or more LM3914 ICs can be cascaded together to create an extended display with more resolution.

SummaryThe world's first full-size interdigitated back contact (IBC) bifacial solar module has been developed and fabricated in Singapore by the Solar Energy Research Institute of Singapore (SERIS) at the National University of Singapore (NUS) in collaboration with the International Solar Energy Research Center Konstanz, Germany (ISC Konstanz). About IBC Solar Cell ModuleThe module technology's first prototype was produced using bifacial ZEBRA IBC solar cells from ISC Konstanz with efficiencies as high as 22%. The cells (battery) were fabricated using industrially proven process equipment and standard industrial 6-inch n-type Cz monocrystalline silicon wafers. The module's structural reliability is ensured by using a double-glass insulation technique perfected by SERIS since 2009. Encapsulated using the double-glass structure, IBC bifacial solar modules could offer a longer warranty period of 30 years or more. Furthermore, by utilising the bifacial nature of the solar cells, as much as 30% extra power is generated by the double-glass module due to reflection of sunlight from the ground ('albedo') towards the module's rear surface.  Dr Wang Yan, Director of SERIS' PV Module Cluster, is ecstatic about this new product. "With SERIS' new module design, panels with 350 Watts front-side power can be made with sixty 23% efficient screen-printed IBC cells. Considering an additional 20% of power via the panel's transparent rear surface, each 60-cell IBC bifacial module will produce a stunning 400 Watts of power in the real world." IBC Bifacial Module FeaturesAll back contact: This eliminates metal shading losses from the cells' front surface. As a result, the module can achieve higher current and efficiency outputs.Bifacial nature: The module is able to absorb light from both its front and rear surface, with a bifaciality of 75%. This enables the module to convert sunlight that enters via its rear surface, as a result of reflection from the ground and the surroundings.Double-glass structure: The cells are encapsulated between two glass panes using polyolefin elastomer (POE), which guarantees a long module lifetime in the field.Low-temperature interconnections: This prevents warping of the IBC cells due to heating.Specially designed & customized electrical junction box: This prevents shading of the rear surface of the bifacial IBC cells.Industrially feasible solar cell and module fabrication process and equipment: This enables the module to achieve high efficiency at lower cost and means that the technology is ready for industrial production Different view about IBC Bifacial ModuleDr Radovan Kopecek, founder of ISC Konstanz, Director of Advanced Solar Cells and Lead Scientist for ZEBRA development since 2009, has ambitious future plans for this technology: "Many people now might think that putting highly efficient IBC cells into bifacial modules does not make sense - but our consortium will prove them wrong. The ZEBRA process is extremely simple and cost-effective and so is the module manufacturing process. In large bifacial systems, this technology will lead to the lowest LCOEs ever. Bifaciality is quickly gaining popularity and, since a few weeks ago, one can also simulate the bifacial advantage using PVsyst - such developments will give many bifacial technologies the breakthrough in the PV systems arena".  Prof Armin Aberle, SERIS CEO, is also enthusiastic about the development. "IBC cells are famous for their efficiency, reliability and durability in the field. The newly developed IBC bifacial module is a testimony of SERIS' R&D capabilities in the PV module technology sector. The module technology offers world-class front side power while providing free extra power from the rear side. As a result, it has excellent LCOE potential" he explained. "The prototype module made at SERIS serves as a proof of concept for mass production. The next step will be to transfer the technology to industrial partners." He believes that such a high-power product could be available in the market within two years. The world's first full-size IBC bifacial module fabricated by SERIS displayed at the booths of SERIS' industry collaborators Centrotherm Photovoltaics AG (booth #360, E3) and SPIC Xi'an Solar Power (booth #330, W1) at the SNEC (2017) International Photovoltaic Power Generation Conference & Exhibition (SNEC PV POWER EXPO), Shanghai, China, from 19 to 21 April 2017.
