4.3Design description
4.3.1Cloud computing platform system
Enterprise rental cloud computing platform：
The company rents cloud platform services to Wan shop palm and provides operation and maintenance of business functions from Wan palms. That is, the enterprise headquarters does not need to consider the computer room, server, bandwidth, etc., the front-end store equipment video and data upload to the cloud platform. The enterprise can achieve the same function as the self built system through the designated account of the client.
In data security, Wan shopkeeper uses SSL authentication encryption technology, all data on the public network using ciphertext transmission, to ensure the security of data transmission.
At the same time, Wan Dian palm cloud service is responsible for daily operation, upgrading and maintenance of the system. When a system fails, a professional cloud service team will deal with it first to ensure that the system runs in a timely manner.
4.3.2Shang Chao and store front-end equipment
Passenger flow analysis：
PC4 passenger flow hot spot sensor is installed directly above the entrances and exits of Shangchao and stores to open the passenger flow statistics mode for collecting and analyzing passenger flow data. By using stereoscopic image recognition technology, the passenger flow in and out direction can be distinguished according to the setting and the passenger flow in and out data can be counted separately. Submit statistics to the platform through the external network or local.
Hot spot analysis：
PC4 passenger flow hotspot sensor is installed above the important goods area in Shangchao and stores. The hotspot statistic mode is opened, the internal area of the image is divided, and the number and time of customers'stopping in the area are divided by video identification, and the trajectory map of people's flow is periodically brought out.
Passenger Flow Hot Sensor, Embedded Hardware Design, Supports Roof Installation, with Wide Angle Lens, Supports WiFi. Built in video analysis intelligent algorithm, real-time statistics of the number of passengers in or out of regional passenger flow or regional trajectory map. The detection width is less than 5 meters, the recommended installation height is 2.8~4.5 M.
4.3.3Installation method
Passenger flow statistics：
Installation of the suction roof above the entrances and exits of Shangchao and stores should be guaranteed to be between 2.8m~5m in height and 2.4m~5m in width.
Passenger flow installation
The installation height 3M corresponds to the detection width 2.9m; the installation height 3.2m corresponds to the detection width 3.4m;
The installation height 3.5m corresponds to the detection width 4.1m; the installation height 4~5m corresponds to the detection width 5m.
Hot spot analysis：
Above the commodity and the main activity area, the ceiling installation, the video detection range is wider than the passenger flow, the installation height is recommended between 2.8 m ~ 5 m, the corresponding detection area is 15 square ~ 40 square.
Hot spot installation
4.3.4Power supply design
Centralized power supply is recommended for the whole system, which is output to the front-end equipment through switching power supply after voltage conversion, and RVV2 * 1.0 cable is used for DC power supply line.
The steady-state voltage deviation is not greater than±2%；
Steady state frequency offset is not greater than±0.2Hz；
The voltage waveform distortion rate is not greater than5%。
4.3.5Network design
1、Network transport protocol requirements
The system network layer should support the IP protocol, and the transport layer should support TCP and UDP protocols.
2、Delay time of information transmission
When information (including audio-visual information, control information and alarm information) is transmitted over IP network, end-to-end delay time (including the time spent in the process of information collection, coding, network transmission, information decoding and display at the sending end) should meet the requirements: the front-end devices and signals are directly connected The end-to-end information delay time between the corresponding devices in the monitoring center should not be more than 2s, and between the front-end equipment and the user terminal equipment, the end-to-end information delay time should not be more than 4s.
3、Network transmission bandwidth
Considering the cost of network transmission and other applications, the theoretical value of available bandwidth of the link is about 80% of the link bandwidth. In order to ensure high quality transmission of video images, it is recommended to use light-load design when bandwidth is used, and the upper limit of light-load bandwidth should be controlled within 50% of the link bandwidth.
Super data can be transmitted over the Internet or locally. We can make full use of the existing network resources. The data can be uploaded through the low bandwidth of uplink 384-512kbps.
4、Network transmission quality
The transmission quality of system IP network (such as transmission delay, packet loss rate, packet error rate, false packet rate, etc.) should meet the following requirements:
The upper limit of network delay is 400ms；
The delay jitter upper limit is 50ms；
The upper limit of packet loss rate is1×10-3；
The upper limit of packet error rate is1×10-4。
5、Selection of transmission mode
For the system environment, signal transmission is recommended as follows:
Generally, when the distance between the front end point and the center point is less than 100 meters, to ensure the data quality of the system, the network transmission mode is generally recommended.
When the distance between the endpoint and the center point is far away (over 100 meters), the optical fiber transmission mode is recommended.
Fiber optic transmission is recommended when complex electromagnetic environments, such as accessory motors, must be crossed.
4.3.6Cable planning
In addition to choosing cables that fully meet the standards, the construction must comply with the requirements of GB 50217-1994 "Electric Power Cable Design Code". We propose the following basic requirements:
The length of the cable should meet the distance requirement and avoid the breakage of the cable. If the cable must be connected, the welding method or special connector should be adopted.
The source cable and signal cable should be separately laid.
All cables should avoid harsh environments such as high temperature heat sources and chemical corrosion zones.
All cables should be far away from high-voltage or high-current cables. When it is not easy to avoid, they should be equipped with metal pipes and buried underground as far as possible.
When laying in a building, pipeline materials and laying methods should be selected according to architectural design specifications and buried in the building body.
The cables should be cleaned up before they are threaded. Butter or talc powder should be applied when they are threaded. The cables entering the pipe should be kept straight. There should be no joints and kinks in the cables. The cables should be moistureproof and anti-corrosion after they are threaded.
The cable should be penetrated from the lower part of the equipment and leave some allowance.
Mark and number the cable ends to facilitate checking afterwards.
