Electronic enthusiast network: With the rapid development of global smart energy, the intelligent upgrading of China's traditional power grid will drive the rise of a trillion-dollar industry. Smart grid has received great attention from all walks of life in China and is also rapidly developing. Facing this huge market opportunity, the original semiconductor manufacturers have rushed into the layout of China's smart grid. As an important component of the smart grid, in order to meet the demanding market requirements, smart meter design solutions face major challenges. What strategies will major semiconductor manufacturers around the world take to seize the opportunity in the increasingly explosive smart meter market? How should engineers face new challenges in innovative design? The elites of the major semiconductor manufacturers with strong global smart meter product lines have revealed the trend of smart meters and future development plans. I believe that readers of electronic enthusiasts can get the most valuable market analysis resources from them.
The original elite Meixin product line director-Kristopher Ardis
——Be the security guard of smart meters
Grasp the three key points and break through one by one
In the vigorous promotion of smart grids today, Meixin has also invested a lot of manpower and material resources in this regard. At present, Meixin mainly focuses on three key technologies in the field of smart grid. They are:
-Metering: accurate measurement of electricity consumption
-Communication: Related technologies to ensure the reliability of data concentration and remote control of smart grid equipment
-Security: Not only protect the transmitted data, but also protect the smart grid from potential malicious attacks by making it impossible for attackers to control critical infrastructure.
Kristopher Ardis, Director of Product Line
These three technologies can be said to be the true core of the smart grid, and it is the reason why Meixin pays attention to them. The fundamental goal of the smart grid is to use electrical energy efficiently while adapting to new distribution methods. To achieve these goals, you need to know where the electrical energy is going, communicate data and control signals, and ensure the safety of all communications. Maxim's complete meter-on-chip (SoC) solutions, communication modem chipsets, and advanced security microcontrollers are all based on the above technologies.
Comprehensive solution to protect the smart grid
Today, with the rapid development of smart grids, Meixin also provides other smart grid-related products in addition to smart meters. Kris specifically pointed out that Maxim's ultra-high-precision real-time clock technology can achieve an accuracy of 5 ppm in an industrial temperature range. Such high clock accuracy is exactly what the Chinese market currently needs, and it is particularly important for smart grids where the communication system is not very reliable. In addition, Meixin also has rich interface products, which are convenient for wired systems to communicate. Their integrated protection and isolation technology can protect end users in hazardous environments. For example, users must operate smart meters connected to the power grid.
The original elite of Texas Instruments market development engineer-Sun Dong
——Enclose the smart meter with a full set of solutions
As one of the largest semiconductor companies in the world, Texas Instruments has a relatively broad product line. In addition to MCU, metering, carrier wave, wired communication, ZigBee, and small wireless, they also include the main technologies involved in smart meters, so It can be said that it is the company with the broadest coverage of smart meter application products on the market.
In addition to the chip-level products related to smart meters, Texas Instruments has also introduced some application programs for smart meters and programs that meet international and regional standards. Such as ZigBee SEP2.0, low-power wireless networking protocol stack, electrical energy metering algorithm library, DLMS protocol stack, wireless M-bus protocol stack, OFDM PLC solution in compliance with G3 / PRIME standard, etc.
Sun Dong, Market Development Engineer, Texas Instruments
In terms of smart meters, Texas Instruments mainly focuses on two major aspects. The first is smart meter communication, including power line carrier, wireless communication, and low-power wireless ZigBee; the second is high-precision measurement, including meter SoC products and high-power Precision measurement chip.
Texas Instruments' new and innovative DSP carrier solution
At present, several major semiconductor manufacturers like Meixin and ST have their own power line carrier methods. For this, Texas Instruments also has a complete G3 / PRIME carrier solution. Sun Dong said that they are different from several others:
First, several other companies are using ASIC-specific chips, and Texas Instruments has used its own accumulation in DSP to develop a multi-protocol carrier program based on the DSP platform. Support different standards through the same device platform, including SFSK, FSK, G3, PRIME, P1901.2 OFDM and other solutions. For users, for different markets or different technical standards, users only need to upgrade different software protocol stacks. Introduce the corresponding program without hardware changes.
Second, other manufacturers may only have G3, PRIME or FSK, and Texas Instruments can provide solutions in addition to G3, including SFSK, FSK, G3, PRIME, P1901.2, the coverage of different carrier standards will be more extensive.
Third, Texas Instruments has made relatively rapid progress in the Chinese market, including prototypes and small-scale pilot projects in the State Grid and several large customers. Through the pilot, you can learn some characteristics of the China Power Grid. For these features, Texas Instruments The existing protocol stack and communication features can be modified through software. This flexibility is not available in other ASIC chip manufacturers.
Sun Dong also specifically pointed out that since the smart grid is a market that Texas Instruments is very concerned about, they have established a smart grid business unit in the United States. In addition, there are R & D teams and application engineer teams in the United States. Local marketing team.
