I. Project Overview:
This plan is the implementation plan of the " Changyi Chongyi Base Internet of Things Construction in Chengdu " project. This solution covers the functions of remote intelligent monitoring system data acquisition, video monitoring system, remote camera capture and so on. This system mainly has the following 2 functions:
1. 360-degree real-time monitoring and production process monitoring of key areas and real-time capture of tourists in the play area.
2. Production is mainly achieved through the construction of comprehensive agricultural conditions, monitoring and sensors to achieve crop cultivation, digital management of agricultural production and the basis for providing important parameters for the traceability system .
Second, the implementation plan:
The program is divided into three areas of video surveillance in Chengdu Shangzuo Chongyi Base, a weather station in the park environment monitoring , and a greenhouse environmental monitoring.
2.1 Video area division and camera pixels:
Point 1, 2, 3, 5, 6, 7 each one ball machine. The dome camera used in this project is 6 million pixels. According to the different encoding methods of the camera, each video transmission stream is approximately 2M-8M.
Points 4, 8, 9, and 10 are all guns. The gun used in this project is 4 million pixels. According to the different encoding methods of the camera, the bit stream of each video transmission is about 2M-12M.
A total of 10 points are divided into three groups for transmission, points 1, 2, 3, and 4 are the first group; points 5, 6, and 7 are the second group; points 8, 9, and 10 are the third group.
In the monitoring center, it is assumed that three network bridges perform point-to-multipoint video image transmission with the above three groups of points.
2.2 Video area wireless transmission and camera layout:
2.3 The third group of video layout and bridge layout and function introduction:
The installation monitoring is mainly to arrange three guns on the road location to monitor the main location of the park, and the traceability system provides video collection data. (The secondary development of the interface on the video side is required.) The power supply mode of the camera is on-site power supply type (take the nearest power).
2.4 The second group of video layout and bridge layout and function introduction:
Transmission method: point 6 and 7 can connect the video image to point 5 by wire, and then transmit to the monitoring center through the bridge of point 5. Among them, a network bridge can be assumed at each of points 5, 6, and 7, and transmitted directly to the monitoring center.
Function introduction: Three high-definition dome cameras are arranged near the adoption area, mainly to realize the remote capture function for tourists.
2.5 The first group of monitoring points and transmission bridges are located and implemented functions:
Transmission method: point 1 can transmit the image data to point 2 by wire, and then point 2, 3, and 4 respectively use a network bridge to agree to the transmission to the monitoring center. Among them, point 1 can also assume a network bridge and transmit directly to the monitoring center together with points 2, 3, and 4.
Function introduction: Three high-definition dome cameras and a gun machine are arranged near the personal park, which mainly provide video traceability data for tourists to realize the remote capture function and cold storage vegetable processing (the power supply of the camera is to take power from the nearest).
2.6 Non-point locations and functions of small weather stations :
A small weather station is arranged at the location of the organic vegetable picking field. It mainly monitors the real-time environment of the park to show visitors the environment of the park in real time and traces the source data of the growing environment of the crops. powered by).
2.7 Greenhouse environmental monitoring data and functions:
The greenhouse environment mainly monitors temperature and humidity , light intensity, CO2, PH value, soil temperature, and EC sensors.
Provide online monitoring data for traceability. (The sensor is powered by the nearest power source in the greenhouse).
2.8 Cold storage environment monitoring and function introduction:
Cold storage environment monitoring mainly monitors the cold storage agricultural product storage environment (temperature and humidity) to ensure that the agricultural product storage environment is suitable for the agricultural product storage environment and provides data for the traceability system. (The sensor is powered by the nearest power source).
2.9 Introduction and implementation of camera snap function:
Function: The high-definition camera captures the wonderful moments of visitors in the park and realizes the storage of photos.
Implementation method: the management personnel capture the real-time moments of the visitors in the park through the camera management platform, and then store the photos in the folder built on the local computer.
Third, the video surveillance architecture diagram:
The project is designed around an intelligent digital hard disk video surveillance system (hereinafter referred to as a digital hard disk video recording system) as the main control system. Digital hard disk video recording system refers to a computer hard disk as an image recording medium, which integrates multi-functions such as screen division, switching, PTZ control, video retrieval, network transmission, and alarm linkage. It is a highly intelligent monitoring system. It is based on DVR (Digital Video Recorder), which adds control functions of front-end equipment, alarm information processing functions, and computer network transmission functions to form a complete digital monitoring and alarm system. Among them, the image recording part uses digital video compression technology and uses hard disk video to make the recording, playback, retrieval, and management of images more flexible and convenient. Therefore, it has increasingly become the dominant trend in the development of surveillance systems. Compared with the traditional analog monitoring system, it has a variety of features and advantages: highly integrated functions, which greatly saves the occupation of system space, simplifies system equipment, and facilitates system maintenance and maintenance; operation is simpler, intuitive, and the interface is more friendly, User-friendly; network remote monitoring and system networking are realized; the picture quality is clearer; large record capacity, convenient and quick retrieval, and more conducive to preservation; higher security, with strict input security measures and anti-counterfeiting, preventing video data from being captured tamper.
