Recently, Shanghai Metrology Institute research project "Internet of Things ZigBee system traceability research and calibration device to establish" passed the expert acceptance. The development of this project will provide technical support for the development of China's Internet of Things industry.
Acceptance Experts Group agreed that the project developed ZigBee system calibration device to achieve the ZigBee tester calibration, the technical indicators have reached the international advanced level. The compilation of the national measurement specification "ZigBee Tester Calibration Specification" completed by the project team provided a technical basis for the calibration of the ZigBee Tester nationwide. The project not only solves the problem of traceability of the ZigBee tester, but also provides technical support for the development and application of ZigBee products and will serve for the development of China's Internet of Things industry.
Currently, as China's Internet of Things industry enters a fast lane of development, ZigBee is being accepted by more and more users in China as a short-range, low complexity, low power consumption, low speed and low cost bidirectional wireless communication technology. Used for data transmission between various electronic devices with short distance, low power consumption and low transmission rate. The M2M (Machineto Machine) industry in the Internet of Things network is widely used in smart grid, mobile POS terminal, supply chain Automation, intelligent buildings, digital medical, telemetry and other fields, has great potential for development.
It is widely used in the construction of the projects e. G. Prospecting, railway, road, port, bridge, water conservancy and hydropower, well, industrial and civil construction, geological exploration, especially used in mining wireline diamond core drilling and inclined hole wireline core drilling, etc.
1.Products Description:
The mast (derrick) type is generally classified as A type, K type, tower type and mast type etc.
A type mast, its leg section is rectangular or triangle shape, with better loading capacity and stability,connected with pins between sections, installed at low level and erected or lowered down integrally by drawworks and A-frame.
K type mast, namely front opening mast, its transverse section is a shape truss structure, its both sides are composed of several pieces or segments, its back is rigid frame or pole system of truss, connected with pins or bolts between segments and members, may be installed at low level and erected or lowered down integrally by drawworks or hydraulic cylinder, has the advantages of convenient installation and teardown, excellent rigidity.
