The application foundation is good As early as 2001, the State Grid Corporation launched a major application of wireless sensor networks in the distribution network. Although there were no large-scale deployments at the time, this laid a good foundation for China's smart grid to attract Internet of Things as an important part of it. During the "Eleventh Five-Year Plan" period, the State Grid Corporation of China and China Southern Power Grid Corporation invested more than 1.1 trillion yuan in power grid hardware and management, which has effectively boosted the level of informationization in China's power grid industry, thus creating a good application foundation for the Internet of Things. The “SG186 Project†that the State Grid Corporation began deploying in 2006 is one of the major projects. On August 7, 2009, Premier Wen Jiabao of the State Council visited the Wuxi Micron Nano Sensor Network Engineering Technology R&D Center and inspected and delivered an important speech, stating that “the establishment of a Chinese sensor information center or a 'China Sensing Center' as soon as possible.†Wuxi, Nanjing, Fuzhou and other places have formulated the Internet of Things application industry plans, and both have applied the Internet of Things (IoT)-oriented grid application as an important pilot project to implement and promote this, which has provided strong traction for China’s Internet of Things (IoT) application for grid applications.
A phased development trend will be presented. Industry insiders expect that the IoT-oriented grid application will be deployed according to the "Pilot Applications - Scaled Application - Deep Application and Upgrade Improvement" model, which is specifically divided into the following phases.
Pilot application stage: At present, China's IOT industry standard system is not yet mature. At present, the standard developed by the National Sensor Network Standards Working Group is mainly the communication standard, and the standard system for the electric power industry has not yet been formed. Because the standard system is difficult to quickly improve in the short term, if large-scale deployments are started before the standards are fully developed, it may lead to great risks in the future operation and upgrade of the power grid. It is expected that the IoT-oriented grid applications will most likely be in 2011. Pilot application phase.
Large-scale application stage: On June 29, 2010, the “Smart Grid Technology Standard System Plan†and “Smart Grid Key Equipment (System) Development Plan†issued by the State Grid will revise the technical standards required for supplementation between 2011 and 2015. Basically build a smart grid technology standard system. Therefore, it is expected that during the period from 2012 to 2015, the application-oriented IoT applications will enter the stage of large-scale application as the standards continue to improve. At that time, market demand will likely show a growth trend.
Popular application and upgrade stage: During the 2016-2020 period, as technology continues to innovate, domestic and international standards are increasingly integrated, domestic IoT products and solutions for power grid industry applications continue to mature, and national information security for the power industry With the continuous improvement of the control system, the application of the Internet of Things (IoT) for power grids will enter the stage of popularization, application and upgrading.
High Speed Door Motor And Control Box
Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.
About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.
About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: <16 ㎡; Daily operating time: >2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.
The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.
System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.
Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.
The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.
Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.
Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.
High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.
Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
