基于北斗短报文安全传输的用电信息采集系统应用研究

Application research of power consumption information collection system based on safe transmission of Beidou short messages

提出的北斗用电信息采集安全传输系统可解决电力设备在信号盲区无法采集数据的问题,系统中的北斗设备加入安全传输机制,使用加密模块对短报文数据进行加解密处理,提高短报文传输信息的安全性。经过测试对比表明,增加安全密钥协商过程会增加部分时间消耗,但仅占数据召测耗时的一小部分,不影响整体召测时长。实际测试环境下验证系统传输数据有效可靠,且北斗通信成功率可达95%以上,当引入重传机制召测数据完整率可达100%。数据召测结果以及电力用采主站接入的情况显示该系统有效可行。

The Beidou electricity information collection and safety transmission system proposed in this paper can solve the problem that power equipment cannot collect data in the signal blind zone. The Beidou device in the system joins the secure transmission mechanism,and uses the encryption module to encrypt and decrypt the short message data to improve the security of the short message transmission information. Test comparison shows that increasing the security key negotiation process will increase part of the time consumption,but only a small part of the time spent on the data collection does not affect the overall collection duration. In the actual test environment,it is effective and reliable to verify the transmission data of the system,and the success rate of Beidou communication can reach more than 95%. When the retransmission mechanism is introduced,the data integrity rate can reach 100%. According to the data collection result and the main station access,the situation shows that the system is effective and feasible.
