Abstract With the development of computer networks, network open, shared, the degree of interconnection grow accordingly. Internet penetration in particular, makes commercial digital currency, Internet banking and other new business network to the rapid rise of network security issues become increasingly important. At present the network insecurity is a major factor in the agreement, systems and databases, such as the design is defective. Interconnection general use TCP / IP protocol, it is a cluster of industry-standard agreement, but the agreement cluster in the formulation of the beginning of the security problems and do not consider too much agreement there are many security flaws. The operating system, due to the current use of the computer network operating system in its structural design and code design emphasis on considering the convenience of the system, resulting in a system in the remote access, access control and password management and security, and so there are many loopholes. Similarly, the database management system (DBMS) there are rights management, data security and remote access, and many other aspects of the DBMS or application process can advance placement in intelligence gathering, controlled stimulate destruction procedures. Visible from above, against the agreement, systems and databases, etc., whether their own design defects, or due to human factors in all kinds of loopholes, some are likely to be another attempt to use the network hacker attacks, the establishment of a firewall is essential The. Firewall by the network managers to protect their networks from the outside world but to allow unauthorized access and Internet connectivity and develop. It is mainly composed of packet filtering state detection circuit layer gateway agent services. Before the three main applications In the network layer, the latter two in the application layer, since packet filtering firewall router is a common mechanism. Therefore, it is necessary to introduce filtering routers. Filtering routers and outlined the work flow. So to ensure the security of information networks Must be familiar with the hacking attacks of the general process, on this basis can we develop preventive strategies to ensure network security.

The exaltation of the living level along with the people, the fast fierce development, frozen food and fresh food of the agriculture by-product and the food processing industry is widespread among the consumer welcome, the people's quantity to the food and the need of the structures raise continuously, the cold database protects the fresh function to seem to be count for much.The cold database is the food cold the basic facilities that process, save, protect to the low temperature of the easy food of 腐 fresh, protect the quality and process to circulate to guarantee the food quantity and insure the food safety to have the important function, is the center link that the food refrigerates the chain.The intelligence of the cold database supervise and control and the management become the cold database usage in is important problem.In recent years, thered has been equal part of cold databaseses using the calculator supervision measure.Large slaughter house in modern, for saving a great deal of meat product, must carry on the control to the temperature and degree of humidities of the cold database, make the control system automation the degree raises consumedly, the temperature control precision, economy energy, raised the stock product quantity, create to protect the fresh environment bestly, real attain to protect the quality, protect the tasty and protect the nourishment.This text introduces a kind of cold database intelligence that take a machine as the core to supervise and control work principle and its hardware design and software designses of the system.Adopt the control centre that a machine of AT89S51 is the temperature supervision system, spread the feeling machine to carry out the cold database intelligence supervision system according to the temperature, degree of humidity, carry out to two cold databases of slaughter house of temperature, degree of humidity carries on the examination, control, and have the function of report to the police.

Summarized as follows: wireless location system design and production Radio technology from the beginning of the twentieth century, radio direction-finding as an important branch of which is widely used in radio management, military reconnaissance, traffic navigation, search and rescue, astronomical observation, wildlife tracking and so on. Single-chip microcomputer as the number of the world's most widespread application of micro-controllers, the modern human life used in almost every piece of electronic and mechanical products will have a single-chip integration. The design of the Wireless Location System has more than two applications, combined with the number of electricity, power module, as well as the high-frequency and other related expertise. Paper briefly introduces single-chip radio technology with the background and development, and then elaborated on the work of wireless positioning systems theory and design of hardware circuit design and software.希望能帮上你。
