Vehicle Tethered Balloon Monitoring System Successfully Completed Security Mission for Shanghai World EXPO 2010 TEXT SIZE: A A A
The Shanghai World Expo 2010 was closed perfectly on Oct. 31. The payload systems and relevant supporting systems for vehicle tethered balloon monitoring system, which was jointly developed by the Academy of Opto-Electronics (CAS), Changchun Institute of Optics, Fine Mechanics and Physics (CAS), Shanghai Institute of Technical Physics(CAS), No. 23 Research Institute of China Electronic Technology Corporation Group, Beijing Guoke Huanyu Space Technology Co., Ltd. and Beijing StarNeto Technology Development Co.,Ltd, has completed the security mission and made a great contributions for the security and technology display of Shanghai World EXPO 2010. The whole development activities were launched and organized by Academy of Opto-Electronics (CAS).
The opto-electronic monitoring platform of vehicle tethered balloon monitoring system is composed of a series of  optoelectronic equipments such as visible light high-definition cameras, infrared cameras, hyperspectral monitoring system, meteorological radiosonde, information transmission system, data management system, gyro-based stabilization system, telemetry and control system and power supply system. The platform plays a key part for the vehicle tethered balloon monitoring system to monitor the Expo Park during the opening of Shanghai World EXPO 2010. It can simultaneously acquire HD images, temperature information, spectral information and location data of the Expo park objects. Additionally it can supply information for atmospheric stratification and accurate weather forecast.
Vehicle tethered balloon monitoring system was launched near the Bureau of Shanghai World Expo Coordination Building. Its working height is 300m (maximum height is 1000m). The system can be operated under various severe atmospherical conditions (high temperature, high humidity, strong wind with the speed of 20m/s). The clear and HD images acquired by optical cameras were transmitted from air to the ground, which was then transferred by optical fiber network to the head quarters and key departments such as the Expo park police station, Expo Operations and Administration Center, Shanghai Municipal Civil Defense Office, Shanghai Public Security Bureau Center, Shanghai Municipal  Traffic and Transportation Monitoring Center, Shanghai Municipal Emergency Command Center, China State council Emergency Command Center for Expo. The balloon system and opto-electronic monitoring platform endured the high temperature, high humidity, strong winds and other harsh atmospherical conditions during 184 days of EXPO opening. The system had been launched successfully more than 80 times, while the longest consecutive operation time was up to 12 hours. When visitors in the EXPO Park is over 700 thousands per day, the balloon system should be launched at night and the optoelectronic monitoring platform would operate at night. Each time when emergent events happened, the optoelectronic monitoring platform could immediately seize the image of event location and sent the first-hand high-definition image to the head quarter of ground, which played an important role in emergency response and treatment.
In order to ensure the special security mission for Shanghai World Expo 2010, a temporary office was established in Pudong and a mission group was formed under the care of Academy of Opto-electronics (AOE). More than 10 engineers were sent to Shanghai to conduct the operation and supply technical support. The engineers have stayed in operation site for a total of 220 days. They have made a great contribution to the success of Shanghai World Expo 2010. The Vehicle Tethered Balloon Monitoring System was awarded a special prix for its contribution to the success of Shanghai World EXPO 2010 and its technical innovation.
