Early reading of finance (August 23)

  Macroeconomics and Policy China's economy has entered a medium-speed growth period. The miracle of rapid economic growth is difficult to reproduce. Lianhe Zaobao: China's macroeconomic forecast and analysis China's economy is less likely to have a "hard landing." However, if the US economy falls into a second recession, China's GDP growth will slow down to 8.24% next year, and the consumer price index will be 3.95%, which is lower than the 4% policy target... Ministry of Commerce: Three-level planning enterprise business credit construction "Economy The reporter recently learned from authoritative sources that the "Guiding Opinions on Strengthening Credit Construction in the Business Sector during the Twelfth Five-Year Plan Period" (hereinafter referred to as "Opinions") has been finalized, and the Ministry of Commerce will officially issue it in the near future. "This is the first guiding opinion for the construction of commercial credit in China. It is also the first time to clarify the framework of the government's credit construction in the business sector. It plans the construction of business credit in the next five years from the three levels of credit moral culture construction, credit system construction and commercial credit application. Insiders of the Ministry of Commerce disclosed to the "Economic Information Daily" reporter... Monetary policy and exchange rate China's monetary policy stabilized. Renminbi was promoted to a near-term macro-control mechanism. 7-day Shibor interest rate is almost equal to 5%. Interest rate is closely related to the central bank's interest rate funds. Continued volatility, market interest rates rose for the third consecutive trading day, and the Shanghai Interbank Offered Rate (Shibor) continued to rise on the 22nd. The 7-day interest rate approached 5% after breaking 4% on Friday, and the overnight interest rate also stood. 4% high. In the inter-bank bond market, the 1-day and 7-day repo rates also rose above 4% and 5%, respectively, while the 3-day interest rate soared 127 basis points to 4.996%. "The days of borrowing money are really sad." Bank traders lamented. Monetary policy is more cautious Recently, the central bank's open market operation has not only restarted the three-year central bank bill that has been suspended for nearly one month, but also the interest rate of the central bank bills issued last week has risen across the board, causing high concern in the industry. Li Yiping, a professor at the School of Economics of Renmin University of China, and Zhang Hongfeng, director of the Economic Research Institute of Shandong University of Economics and the special commentator of the newspaper, said in an interview with the Economic Herald on the 21st that the central bank will be more cautious about raising interest rates and the possibility of raising interest rates will be further reduced. . Zhang Guohong: The appreciation of the renminbi or an important choice for future macroeconomic regulation The market is highly concerned that when the US debt crisis has a huge impact on the global financial market, the current pace of RMB appreciation is gradually accelerating. This phenomenon is also worthy of attention. If we take the initiative to choose the exchange rate instrument in combination with the latest expression of the People's Bank of China, the appreciation of the renminbi may become an important choice for China's macroeconomic regulation and control policy adjustment under the current European and American debt crisis. This change in the macro-control of the international market trend worthy of attention ... the US economy into a second recession or economic studies show: the United States if a double dip is not a serious impact on China Studies "China's macroeconomic quarterly model" results show that if the US economy in 2012 In the "secondary recession", although it will have a certain impact on China's import and export, employment, but if the macro policy is properly handled, China's economic growth will still reach 8.24%, and will not be seriously affected as in 2008...

STEP Inverter

AS380 series elevator integrated drive controller is the new generation of state-of-the-art elevator-specific control and drive device. With full consideration of the safety & reliability of elevator;inherent characteristic of elevator operation and specific feature of potential energy load for elevator, AS380 series elevator integrated drive controller adopted advanced technology of frequency control of motor speed and intelligent elevator control as well as the integration of control & drive of elevator to make the further improvement of the product performance, easy-to-use property and cost efficiency.


Main features

a) Prefect integration of control and drive of elevator. The whole device features compact structure and small size, fewer connections, which is characterized as high reliability and easy-to-use property and cost-efficiency.

b) Double 32-bit embedded microprocessor jointly finish the elevator operation and motor drive control

c) Redundant safety design , double safety protection for control processor and drive processor to achieve the maximum safety guarantee for elevator travel

d) The design requirements of anti-interference capacity go beyond the highest standard in the industrial design requirement. e) All CAN bus communication make the whole system connected easily, data transmitted strongly, and more reliable.

f) The adoption of the advanced direct landing technology make elevator running more efficiently

g) The advanced multifunctional elevator operation mode can fully meet various needs of customers`

h) Advanced group control feature. Not only compatible with the traditional group control mode of up to 8 units, but also support the new group control of destination floor distribution.

i) The adoption of advanced vector control technology can make the motor speed adjusted well for the realization of the best elevator comfort.

j) Adapt to both synchronous motor and asynchronous motor.

k) Newly-developed none-load sensor-activated compensation technology provides excellent starting comfort to elevator even if no counterweight is installed.

l) To adopt incremental ABZ encoder to realize the synchronized control of motors. To adopt the none-load sensor-activated compensation technology to achieve the excellent start-up comfort.

m) New PWM dead band compensation technology can effectively reduce the motor noise and loss of machine.

n) Dynamic PWM carrier modulation technology can effectively reduce the motor noise.

o) Auto-tuning phase of synchronous motor without encoder

p) Asynchronous motor is not required for motor parameter acquisition process once the motor parameter is set correctly. The convenient static motor parameter acquisition process is available If is impossible to acquire the exact motor parameter on site. So there is no need to hoist the car and etc in this way.

q) The hardware is the 6th generation of module with the junction temperature resistance up to 175℃. Low loss for switch and connection to ensure the long use life.
