The Expo Parking System Shines - Tigerwong

The first China International Import Expo was grandly held in the parking lot system Shanghai National Convention and Exhibition Center. Holding the International Import Expo is a great creation of China, from November 5 to 10, 2018. This is the first national level Expo with the theme of import so far, which will play a great role in promoting the field of world trade. The Expo attracted more than 3000 enterprises from more than 130 countries and regions to participate in the exhibition, and more than 5000 exhibits made their debut in the Chinese market. The Expo is large-scale and unprecedented. The National Convention and Exhibition Center has a total construction area of 1.47 million square meters and an aboveground construction area of 1.27 million square meters. There are a large number of visitors to the exhibition, and the number of visitors to the museum exceeds 250000 per day.

Tight time, such a large-scale exhibition security task. The task is heavy. The dredging of the network is the premise for the smooth development of the Expo security work. Due to the large flow of people in the exhibition hall and the channel congestion of public network communication, reliable private network communication needs to be adopted to ensure the communication between security personnel and ensure the efficient dredging of security command and dispatching during the Expo. However, at present, the conservative narrowband communication network in the public security industry can only provide voice and short data services, does not support video and broadband data services, and cannot meet the requirements of new services such as large-scale event security multimedia command and dispatching. In order to help customers solve this problem, Huawei, together with Shanghai Sanji Electronic Engineering Co., Ltd. and the National Convention and Exhibition Center, has arranged a complete set of ELT integrated command wireless broadband private network system to ensure multi-party command linkage.

Provide end-to-end solutions and products, and ELT integrated command solution is oriented to cloud, management and end. Through the "integration platform", the "integration network" and the "integration terminal", the "three objectives" of the command and dispatching system are "visible, accessible and mobile". Under the four business scenarios of daily policing, emergency handling, major activity guarantee and VIP security, an integrated command system of "situation, direction, operation and supervision" with up-down linkage, horizontal response and efficient operation is built. Visual command: ELT integrated command platform provides an open and unified business esdk interface for platform integration. Through voice fusion, data fusion, video fusion and map fusion, the information association and business linkage between police receiving and handling, PGI professional systems and cross departments are realized, and one map command is realized through multi-dimensional map. Mobile command: a large network based on ELT wireless broadband private network and network integration.

Integrate various heterogeneous communication networks to realize the interconnection between ELT and radical narrowband cluster systems such as public network voice, PDT and tetra. With the characteristics of high bandwidth, wide coverage, high-speed mobility and strong anti-interference ability, Huawei ELT wireless broadband private network adopts advanced ltelong term evolut (temporary evolution) broadband technology. The uplink and downlink throughput can reach 50mbp and 100mbp respectively. An ELT private network can carry voice, video and data services at the same time. The ELT private network arranged in the National Convention and Exhibition Center adopts 1.8GHz frequency band and is dedicated to the private network, which can provide stable and reliable communication for on-site security personnel.

For the large-scale venue scene of the National Convention and Exhibition Center, the two deployment modes of wide coverage of outdoor large antennas and accurate coverage of indoor distributed small antennas are fully combined to realize seamless coverage inside and outside the museum, including national trade and investment exhibition, enterprise business exhibition, conference forum and other places. Including handheld broadband cluster terminals and accessories. In this security activity, ELT private network provides a series of single police equipment. The security personnel of the National Convention and Exhibition Center are equipped with several ELT large screen broadband cluster terminals ep820 for patrol and verification in key areas such as traffic checkpoints around the exhibition hall, densely populated areas of the exhibition hall and entrances and exits of the exhibition hall. A single ep820 terminal supports voice, video, data and GI services at the same time.

One machine integrates voice walkie talkie, picture transmission, law enforcement recorder and police communication, which can reduce the burden of on-site security personnel. The parking lot system and the ELT wireless broadband private network system of the National Convention and Exhibition Center are connected with the existing alarm receiving and handling system and video private network system of the Municipal Bureau Command Center. The on-site security duty personnel can return the on-site video to the Municipal Bureau Command Center in real time, and the commander can clearly see the on-site situation and quickly give correct instructions. Various police application apps are installed on the ep820 terminal, and the on-site security personnel can quickly carry out human ID comparison, face recognition, police office and other services. There is a blind area in wired video monitoring.

ELT integrated command provides rich wireless mobile video return solutions, which can be used in major event guarantee, emergency disposal, VIP guard and other scenes. It includes a variety of video return modes such as serial ELT broadband cluster handheld terminal, control ball, cpecstompremisequip client terminal equipment) camera "and UAV. It is dedicated to ELT private network. The control ball and CPE terminal can still return HD video under the condition of 430km / h high-speed movement, which can meet various scenes such as single alarm, vehicle mounted and air HD wireless video return, Open up the wireless broadband channel for mobile face recognition and license plate recognition. In addition to equipping security personnel with ELT broadband cluster terminal, ep820 also deployed more than 10 sets of "eltcpe camera" devices as emergency plans. By installing CPE and camera on the police car and simple tripod, the security of entering the Expo.

In case of any emergency in the National Convention and Exhibition Center, control can be deployed anytime and anywhere to achieve no dead corner monitoring. Through the ELT integration platform, it can realize the interconnection with the existing video private network of customers. The ep820 handheld terminal and CPE vehicle camera can return the video to the monitoring screen of the command center in real time. The commander and on-site security personnel can also call the sky eye video of each place of the Convention and exhibition center through ep820 anytime and anywhere to realize efficient police patrol video linkage.
