China's CNC machine tool output increased slightly in July. China's machine tool industry operating data show that China's CNC machine tool output growth continued to show a slight upward trend in July, the year-on-year growth rate of 68%, higher than the level of 45% in June. Judging from the absolute value of output, the output of CNC machine tools in July reached 19,500 units, which was lower than the 20,300 units in June, which was a month-on-month decline. It can be seen that the increase in the growth rate of CNC machine tools in July was due to the base effect.
The numerical control rate remains high. After entering January 2010, under the influence of factors such as economic transformation and industrial upgrading, the output of CNC machine tools continues to expand, which has led to a continuous increase in the numerical control rate of China's machine tool industry. In July, the CNC ratio of China's machine tool industry was 29%, compared with June. The numerically controlled rate of 30% is basically the same and maintains a high position; this shows that the demand for CNC machine tools is increasing faster, which is also consistent with the transformation and upgrading of China's manufacturing industry.
Downstream drivers have slipped. The automobile and construction machinery industry is the main downstream of the machine tools, and it is also the main driving force for the development of the machine tool industry. After entering 2010, affected by the base effect, although the growth rate of China's automobile output and construction machinery production declined to a certain extent, it still maintained a positive growth. From the perspective of the auto industry, the year-on-year growth of China's automobile output in July was 17%, which was lower than that in June, and the year-on-year growth rate fell for 5 consecutive months.
This system can realize the direct communication above and below the coal mine, the wireless communication system and the wired communication system can be organically integrated, and the user can realize the roaming of the underground and the underground.
Wireless mining communication networks transport data, voice, and video, supporting applications that are essential to efficient and safe mine operations. The network is typically comprised of both fixed and mobile nodes. Wireless communications products operating in this setting must be ruggedized and be capable of handling extreme temperatures and weather conditions, shock and vibration, as well as dirt and dust. Often, the active mining site is transient so the network must be easy to move and setup in different locations around the mine every few months. To provide maximum benefit, wireless mining communication networks must offer broadband speeds and form a flexible and reliable foundation to securely support multiple applications on one cost-effective physical infrastructure.
