Deutz-Fahr is a Europe brand who produces lots of tractors and other farm equipments, while KHD acquired the FAHR, a leading company in the market of agricultural equipments, in 1968. Then the Deutz-Fahr was found. The range of horsepower are from 50 hp to 300 hp. It almost meets all the power needs of agricultural operations. The parts we can supply are for the trators which installed with Deutz engine, like 900 series, 1000 series, and 2000 series, like overhauling parts, Electrical Parts, cooling system parts, fuel system parts.

Video surveillance and access control applications <br> <br> in campus security system, video surveillance system with LCD screen can monitor the entire campus classroom building, laboratory building, student dormitories, student cafeteria, main campus entrance and important public places. Through the application of network video and audio monitoring technology, the entire network can be centrally managed and remotely called. In emergencies or alarm events, real-time monitoring through LCD splicing screens improves command and dispatch capabilities.
At present, there are three main applications in the campus video surveillance system . One is widely used in campus safety construction; the second is the management of school buses and the timely monitoring of the safe operation of school buses; the third is examination management, and the “National Education Examination System†required by the Ministry of Education. The establishment of an Internet search through the "video surveillance network covers all the establishment of test centers, the implementation of the monitoring command over the examination process and the security room. From the big screen splicing screen can clearly control the real-time security status of all corners of the campus.
In terms of campus management, we should start from the gates of the campus. Effectively controlling the entry of outsiders is the basic guarantee for campus safety. Access control systems are an important aspect of campus security. Access control helps to strengthen the management and control of students and related personnel on campus. Students and staff access control personnel for identity authentication, access control and management systems, and confirm the passage of time for real-time control and recording, thereby effectively preventing outsiders from interfering with or damaging school safety work. By installing the access control system, management can be promoted, access control awareness and campus safety work responsibility system can be strengthened, visit registration procedures can be strictly followed, and schools can arrange for regular viewing of the LCD splicing screen to achieve effective control of vehicle and personnel entry. 
Air defense, anti-technology, anti-<br> <br> combined for campus security crisis, take the form of civil air defense, physical defense and anti-technology combined, first of all, to strengthen campus security awareness of employees. Through the relevant management regulations, we shall formulate campus personnel restraint behaviors, strengthen safety awareness, and personnel engaged in safety technology prevention shall have the necessary legal basis for professional knowledge, master the basic skills of system operation and maintenance, and master first aid treatment methods.
Strengthen the construction of materials. In the early stages of the campus security system construction and maintenance and reconstruction process, the importance of the protection of campus security systems was fully taken into account. Schools should establish or appoint corresponding management agencies to participate in the school's construction planning and design and construction work. According to the actual situation, they should put forward prevention and use requirements. Pay attention to the application of the security system. Analyze building safety through safety requirements, identify important components of campus guards and common parts, and install video surveillance systems, access control card systems, multimedia teaching systems, intrusion alarm systems, broadcasting systems, electronic patrol systems, and safety facilities. These systems all require a good LCD splicing screen to ensure the safety of children on campus. 
From the current practice of all countries in the world, more and more proportions rely on technology for prevention and technology to prevent campus security are growing. For example, in the United States, a full range of electronic LCD screens are provided for campus planning of camera terminals. Each school is related to each other. If a student accident occurs, the large screen will be displayed on the mobile phone simultaneously. The school will also receive a warning. Others Schools will immediately know and take precautions to avoid the killer who causes greater harm.
Therefore, only relying on air defense and physical defense is far from this level, so that campus security should be added with protection technology and reasonable use of safety equipment, establish a unified and standardized electronic monitoring system, and the connection between the system and related departments. Ensure the maximum safety of the school. Emperor Aidi believes that in the rapid development of information technology, campus security and prevention are far from meeting the needs of air defense. They rely solely on materials, and only rely on technology and human and physical defense to ensure the safety of their children. From the current point of view, a security system that is increasingly scientific, effective, and saves manpower and material resources has become a trend as an important means to ensure campus safety and student management.
