Dalian Prison Digital Radio Communication System
The prison management is an important part of China's public security management. The development of prison law enforcement is directly related to social stability and the long-term stability of the country. With the implementation of the strategy of "strengthening police by science and technology and safe prison" in prisons throughout the country, the Party Central Committee and the State Council require prisons throughout the country to take the task of ensuring prison security and stability as their primary responsibility in order to maintain social security and stability. Safe and reliable radio system is an important part of prison information system, which is good to improving the efficiency of police services.
As an important technical means of prison management, for the radio system, at present, most of the radio systems used in prisons in China are analog conventional communication systems or virtual networks based on public mobile communication networks. Among them, the analog conventional communication systems have some problems in the actual police work, such as serious equipment aging, low frequency utilization, poor anti-jamming ability, insufficient communication security, no data service application and so on. The virtual network communication based on public network can only guarantee the daily voice communication function, and can not meet the sudden and efficient emergency command and dispatching needs in prison department. Therefore, the current prison management communication means has lagged behind the development level of prison informatization, and can not fully meet the needs of daily prison management and emergency communication security under the new situation.
