Analyze the computer room, worrying about maintenance problems
Since the general computer room adopts a stand-alone recovery card and does not have network management functions, the operation of one by one increases the workload of teachers. The maintenance problem of the computer room has increasingly become a big problem that troubles the school work. The specific performance is as follows: first, in resource allocation, a computer class needs to be equipped with 2 teachers, one is responsible for lectures, and the other is responsible for classroom machine maintenance and order management. Increased investment in education; secondly, in daily maintenance, as educational software continues to be replaced, upgrading systems and installing software requires teachers to operate one by one, wasting teachers a lot of time; again, in the classroom effect, the novelty of the network attracts students ’ Looking, students tend to be distracted in class and the teaching effect is not good. In this regard, the school puts forward new requirements for the construction of a new computer room:
First, remote batch installation of software, remote batch upgrade system, remote classroom maintenance, asset information management, remote diagnosis, etc., without having to operate one by one.
Second, it can realize the unified management and system protection of all the recovery cards in the computer room, and can repair and set the parameters of the recovery cards in batches.
Thirdly, it can help teachers to carry out daily classroom supervision, and can prevent students from “misconduct†behaviors in class at any time, effectively control students' classroom learning, and thus improve the quality of teaching.
The combination of main control and remote maintenance has many advantages
According to the school's demand for the construction of computer rooms, Lansha has gathered many years of maintenance and management technology to create a blue sand computer maintenance system that meets the school's requirements for the school computer room, turning the concept of convenience, speed and practicality into reality. As shown in the following architecture diagram, the system consists of three parts: the main control end, the controlled end and the network maintenance card, and the structure is very simple:
The blue sand computer maintenance system is based on the local area network and uses TCP / IP protocol to achieve remote maintenance through coordination between the main control end and the controlled end. The main control end needs to install the main control end software, and the controlled end needs to install the network maintenance card when installing the controlled end software. Because the network maintenance system uses multicast protocol (IGMP) to remotely maintain the controlled terminal, it can support cross-hardware network segments and routing. If the controlled terminal is distributed in the same network segment, one main control terminal can be used to control the whole; if it is divided into N network segments by soft routing or physical, then each network segment requires a main control terminal, Each master also needs to configure the dongle.
After everything is ready, the teacher can activate the system by adding the master data information, use the master to install software, upgrade the system, view the machine hardware and software asset information, detect and maintain the controlled End-to-end type of remote maintenance. At the same time, it can also lock the network, mouse and keyboard to supervise students' classroom learning. Specifically, the maintenance system has the following three characteristics:
1. Unique software distribution function: The system uses Module Generator to make newly installed software into modules, which are distributed to client computers in batches, and the client computers automatically decompress and install them. It takes only 10 minutes to install a set of OFFICE 2003 software in a 200-machine room, and all installations can be completed.
Second, the three major management functions come together: the "asset information management" function can keep track of the hardware configuration information and software information of all computers at any time; the "restore function" function can always protect the security of each computer system and can be used by the main control terminal for all customers The working mode and data cache of the terminal are managed; in addition, the "power management" function can remotely switch on and off the computer, reducing the workload of teachers and making maintenance easier.
Third, the perfect classroom maintenance function: classroom maintenance is mainly achieved through three aspects. First, the "Internet lock" function changes the teacher's traditional visual supervision of the classroom and cuts off the small movements of the students at any time; second, the "mouse and keyboard lock" function adjusts the student end in a timely manner, so that the students can listen to the class and improve teaching efficiency; The "screen monitoring" function can be used to view any student's computer screen at any time to remotely guide students without having to go back and forth to the classroom, and can remotely control the controlled computer to achieve remote detection and solve problems.
Blue sand helps, efficient management shows results
The computer room using the blue sand computer maintenance system can be easily maintained with only one management teacher. Now it takes less than half an hour to install several large-scale software in the entire computer room. It is no longer necessary to toss the entire hard disk back and forth through GHOST or network cloning for the installation of new software. During daily maintenance, as long as the management teacher issues instructions on the main control end, the controlled end can automatically execute the commands, and the classroom can be easily maintained without leaving the machine. In addition, students can also get rid of external interference and go to class with ease, teaching quality has improved significantly, At the same time, it can also save money for schools, and the blue sand computer maintenance system really achieves "multiple benefits".
