"Very convenient, without manual instructions to students how to operate directly in accordance with the instructions of the vehicle system to complete the exam, the Internet upload speed quickly and accurately, the students feel a lot easier." Driving examiner said.
Recently, Jiangmen Mobile in Kaiping, Jiangmen and the local traffic police department jointly deployed car video test Internet of Things, 4G network for the traffic police department to achieve real-time return of test video, driving test subjects for the three tests provide an important basis for judging. The Internet of Things technology has been installed in Kaiping City 12 test car 4G IoT card.
It is understood that, in accordance with the examination requirements of the motor vehicle driver exam three, the exam room need to participate in road test subject three vehicles in real-time position monitoring and real-time collection of operating conditions within the vehicle feedback. In the course of the examination, the real-time situation of the vehicle will be transmitted to the background monitoring management room through the real-time image. The backstage manager registers the vehicle of the examiner, the fixed-point stop of the road section, the abnormality or the fault condition according to the image data to complete the subject Three-way test of the entire record. The transmission line used by the examination system is protected by dual routes. The micro-4G base station is set up for the situation where the vehicle at the departure point is intensively tested. The 3: 3 uplink / downlink rate is set to enable the upload rate to reach 14 Mbps. 4G signal to ensure smooth data transmission, video signal transmission to solve the real-time, to ensure that the video can be returned to the vehicle in real time, to ensure the accuracy of driving test.
"The past three subjects depends on the examiner manual examination, with the car video test Internet of things, through real-time video can achieve accurate determination, effectively avoiding the mistakes made." According to the project technical staff, Jiangmen mobile and local traffic police department to fully communicate , Formulate project implementation plan, provide advanced 4G IoT card and dedicated access channel service, and adjust the antenna direction of Kaiping Nangang Maintenance Center, Kaiping Nanlian, Kaiping and Minkenghong Station to ensure that the road section Good coverage and convergence; newly issued 2 macro-station, 5 micro-site construction tasks of new sites, according to the progress of the opening and delivery operations in advance to improve the road 4G signal coverage, 12 km road test to solve the breadth of coverage.
In order to ensure the smooth progress of the project, Jiangmen Mobile also took advantage of its 4G network coverage. Seven new base stations along the driving test road were newly established, and the existing base stations were adjusted and optimized. The micro base stations were innovatively used to ensure good coverage of 4G signals along the 12 km test line. The data transmission is timely, accurate and safe.
