Relying on the new-generation visual appearance acquisition devices and optimized algorithms, the scanner can provide fast scanning speeds of up to 3,000,000 dots per second in handheld scanning mode and about 0.5 seconds per single page in fixed scanning mode.
During this SCE, Chongqing Institute of Opto-electronics and Information displayed “Wan Zhi Tian Cheng” smart hardware pioneering in China and enjoys core technology and proprietary intellectual property rights and its supporting heterogeneous IoT platform.
This platform’s application scenarios cover many important fields such as communications, safety, lighting, vehicle-road collaboration, and environmental monitoring, which can fully satisfy urban management needs and improve urban management efficiency. By virtue of the unique data mining and brain intelligence algorithm, the platform can consolidate, analyze and process original heterogeneous business data collected, and extract and provide the data of more value to whoever needs them. Thus, the value transformation from original business data to data assets can be completed, and support can be provided for local governments at all levels to achieve the fiscal transformation from “land finance” to “data finance” and leap-frog upgrading through data capitalization operation.
4G explosion-proof smart intercom phone, launched by Chongqing Bluebank Communication Technology Co., Ltd. from Chongqing Airport Based Hi-Tech Park, can be applied to safe communications in dangerous environments where combustibles exist and explosives such as chemical plants, gas stations, and oil refineries. Meanwhile, it can also be extensively applied to special policemen, fire control, gas repair, safety supervision, coal production, transport of dangerous goods, and other fields. On communications, it is a phone that supports worldwide 4G phone function and telecom based on LTE (supporting 3G/4G/CBRS frequency band) and WIFI network that covers the whole world. Meanwhile, it also supports the EVA (Enterprise Voice Assistant) function that is convenient for enterprises.
Chongqing LANKOON UAV Technology Co., Ltd., located in Chongqing Creative Park, is a professional UAV security defense system solution provider. During this SCE, it exhibited its newly-developed UAV low-attitude defense system.
This is a security defense system for early warning that integrates multiple technologies, including radar, frequency spectrum detection, photoelectric identification tracking, and UAV electromagnetic compaction, deception, and parsing protocol, and can be used with flexible networking. Consisting of two major parts of detection and recognition and defense and processing, the system will automatically start corresponding defense units to carry out effective countermeasures and realize all-around, full-time, automatic, all-weather, and all-frequency-band security warning and defense against unreported UAVs.
During this SCE, Chongqing ATEC Technology Co., Ltd. from Airport Industrial Park exhibited its self-developed high-/low-temperature test chamber. Its main products include high-/low-temperature humidity chamber, temperature shock chamber, low-pressure chamber, chamber combined with temperature/humidity/vibration, single-shaft and multi-shaft rotary temperature chamber, rainfall/dust/light/salt spray environment simulation system, vehicle climate/environment simulation and detection system, multi-factor environment simulation system and other kinds of non-standard testing systems, etc.
The products are widely used in national key laboratories and large-scale third-party testing laboratories, and as well as applied in aviation, aerospace, armament, vessel, automobile, intelligent manufacturing, new energy, measurement, electronics, railway system, power, health care, academic institutions and many other important fields of the national economy.
During this SCE, Chongqing GodArrow Inertial Technology Co., Ltd. from Airport Industrial Park exhibited its two products of fiber optic gyroscope and dynamically tuned gyroscope. Specifically, fiber optic gyroscope is built on quantum mechanics and based on the Sagnac effect. Using a laser as a light source, it leverages the optic fiber ring to detect the phase difference between the positive and negative beams caused by the rotation of the optic fiber ring and calculate the rotational angular velocity in inertial space. This product can be applied to angular velocity measurement, inertial navigation guidance, attitude measurement and control, positioning and orientation, platform stability, dynamic image stabilization, and stable aiming, etc.
Another product is dynamically tuned gyroscope, also known as flexure gyroscope, which is a kind of high-precision two-degree-of-freedom gyroscope with non-liquid floated elastic support and belongs to the third-generation high-precision inertial navigation gyroscope. This product is mainly applied to angular velocity, angular position, azimuth, platform gyrocompass, electronic gyrocompass, vertical azimuth datum, course keeper, and geodetic survey, mapping, aerial photography, directional drilling in petroleum geology, etc.
