Description

City pet management system

technical field

The invention relates to an urban pet management system, in particular to an urban pet management system based on remote radio frequency technology combined with a hand-held PDA and a central server.

Background technique

With the improvement of social progress, economic development and people's living standards, pets have become a fashion for people to entertain and pursue quality of life. However, as the city's pet fever continued to heat up, some new social problems also emerged, "dogs barking all over the corridors, feces all over the community, random breeding without a license, but epidemic prevention." What's more serious is that pets, especially dogs, have repeatedly bitten people in various cities. Professor Zhang Yongzhen from the Institute of Infectious Diseases of the Chinese Center for Disease Control and Prevention pointed out: "The third rabies epidemic peak is forming in China!", "Since 1996 Over the past few years, the epidemic of human rabies has rebounded rapidly year by year, ranking first in the death rate and number of deaths from infectious diseases in China for many years, and has once again become a major epidemic that seriously endangers China's public health." Pets are very popular in all parts of my country, and the number of dogs kept in various places About 150 million or so. From January to September 2006, a total of 2,254 cases of rabies were reported across the country, an increase of nearly 30% over the same period last year; since May this year, rabies has become the infectious disease with the highest number of reported deaths in my country for five consecutive months.

The supervision of urban pets has become a hot issue nationwide. In addition to strengthening citizens' moral education, speeding up legislation, and strengthening law enforcement, the development of applicable regulatory technology and equipment has become a technical problem that needs to be solved urgently. There are obvious defects in the existing technical means - it is impossible to remotely identify the legal identity of pets anytime and anywhere, resulting in the inability of law enforcement officers to effectively monitor and manage urban pets. At present, there are mainly the following ways to identify pets:

use traditional cards

Use 2D barcode

implanted chip

The above three methods all need to catch and check pets, and it is not easy to rewrite the recording medium, which has the disadvantages of low management efficiency and high law enforcement costs. On the basis of summarizing the existing achievements in the field of pet identification, the patent of the present invention draws on the latest achievements in the field of wireless communication, and aims at the shortcomings of the above solutions, and proposes a new remote wireless pet miniature electronic identity card. The long-range wireless electronic identity card is hung on the pet, and contains a wireless radio frequency module. The transmission distance of the radio frequency module is adjustable within the range of 3-100. When the supervisor uses a handheld PDA to identify and manage the pet, there is no need to catch and check the pet. Read and write pet electronic ID card. Compared with other pet identification technologies, remote radio frequency pet electronic identification tags have obvious technical advantages. The following is a comparison of several different pet identification technologies:
