DVR in Sanitation Vehicles based on A40i system on module

In July 2019, waste sorting was formally implemented in Shanghai, China, which caused a wave of waves and pushed waste sorting to the forefront. It marks that my country is actively promoting the development of the garbage classification system throughout the country.

According to the nine departments including the Ministry of Housing and Urban-Rural Development, the Development and Reform Commission, and the Ministry of Ecology and Environment jointly issued the "Notice of the Ministry of Housing and Urban-Rural Development and Other Departments on Comprehensively Carrying out Domestic Waste Classification in Cities at the Prefectural Level and Above in the Country", starting this year, cities at the prefectural level and above nationwide will be fully launched. Classification of domestic waste. Before 2025, cities at prefecture-level and above across the country will basically build waste sorting and processing systems.

Needless to say, the benefits of waste sorting and distributing need to be implemented by the government, and the importance of waste sorting must be deeply rooted in the hearts of the people. Let everyone in the entire garbage disposal system, put the important classification and put in place, in order to facilitate the more efficient processing of the back-end garbage.

In the entire garbage disposal system, the disposal of garbage is a key link, but at the same time, the classified collection, transportation, and disposal of garbage are also more important steps.

For cities, especially densely populated large cities, a large amount of garbage is generated every day, but the city's land area is limited, and all garbage transportation and disposal has become a very important issue. Garbage trucks are usually used for urban sanitation work, transporting community and municipal daily garbage, and transporting various wastes. Everyone cannot live without garbage trucks.

With the promotion of garbage classification, the environment for garbage collection and transportation needs to be more and more precise. The quantity of garbage removed every day must be accurately recorded, such as transportation time, garbage source unit, location, and removal unit.

This requires more requirements for vehicle monitoring, remote positioning, and standardized operation.

Necessary functions such as intelligence, networking, and remote monitoring required for clearing and transporting vehicles.

The monitoring system of the Municipal Bureau of Environmental Sanitation generally includes a remote monitoring center for environmental sanitation vehicles and airborne DVR monitoring equipment for environmental sanitation.

The function of the remote monitoring center is to centrally control data and dispatch and manage vehicles. The sanitation vehicle transmits some of its own real-time data to the control center remotely through the network, etc., and displays it on the electronic map of the vehicle management platform, real-time feedback of the vehicle For the specific location, the monitoring center can also set the maximum range of movement of the vehicle through the electronic fence. Remotely monitor the vehicle status. Once the vehicle shuts down the monitoring system or leaves the electronic fence area and other illegal operations, the system will automatically prompt a warning and remind the management staff to pay attention to the vehicle's condition.

The sanitation airborne DVR equipment uses 4G network and Beidou GPS dual-mode satellites to transmit the dynamic monitoring video, sound, and vehicle operating status of the vehicle to the remote monitoring center platform in real time. With a remote real-time language dialogue system, it is convenient for managers to see, hear, know and monitor the status of the vehicle synchronously at the remote end.

Through platform linkage, macro-control vehicle layout, accurate positioning, planning classification collection routes, avoiding congestion, realizing garbage collection, and more efficient operation of the transportation process.

The airborne DVR device has a local video storage function, which can store surveillance video for a certain period of time. When some cases or abnormal situations occur, it is very convenient for managers with management authority to replay the video through the on-board monitoring equipment, or remotely visit the video in the monitoring center.

General airborne DVR equipment is realized by the embedded processor and embedded operating system, combined with video and audio compression/decompression, Beidou/GPS global positioning, 4G/5G wireless communication, GIS geographic information, and other technologies for 24-hour long-term operation equipment. At the same time, it will be connected to multiple cameras, onboard displays, IC cards, and other monitoring vehicle operation sensors. The function is to know the vehicle information such as the situation in the vehicle, the driving track, and the place of arrival.

The intelligence and interconnection of terminal equipment is inseparable from the support of intelligent equipment.

Here we will mention the core component in the smart device-the FET A40i-C core board, which is used to provide hardware and software support for realizing the above scenarios.

The FETA40i-C core board, as a domestic industrial-grade chip launched by Forlinx, is based on the Allwinner industrial-grade A40iCortex-A7 quad-core processor. The main frequency is up to 1.2GHz, and the internal integrated Mali400MP2 GPU graphics processor. Industrial control products, stable operation 7x24 hours under the working temperature of -40℃~+85℃. Support Linux 3.10 operating system. Very suitable for products of on-board monitoring equipment.

Features:

1. High-definition picture quality and audio output: support dual-screen different display and multiple display interfaces RGB/MIPI/dual LVDS/HDMI, 1920x1080@60fps; internal integrated audio codec, no need for external expansion audio chip, and support a variety of hardware Video codec format.

2. Rich network communication: Onboard 1 Gigabit network, 1 100M network, support WIFI/BT4.0, support 4G full Netcom module, wireless devices can easily realize the interconnection between LAN and WAN.

3. Multi-channel video capture: support dual-channel DVP parallel camera and 4-channel CVBS-IN analog camera interface, which can perform multi-channel video recording.

4. Rich interface resources: integrated UART*8, SD*4, USB*3, SPI*4, IIC*5, PWM*8, SATA, etc., used to support hard disk, GPS positioning.

The supporting development board leads to the above-mentioned common interfaces LCD*1, LVDS*1, TVIN*4, USB*3, WiFi*1, SATA*1, HDMI*1, UART*6, LAN*1, which is very convenient for the early stage of the project Evaluation and development.
