    • The invention discloses a method for monitoring and evaluating pipeline leakage of an LNG (Liquefied Natural Gas) receiving station wharf, which comprises the following steps: quantitatively detecting the flow of liquefied natural gas in the pipeline and the pressure of liquefied natural gas on the pipeline by a wireless sensor network node; An expert system for determine an initial confidence rule base according to expert experience or domain knowledge; Establish a confidence rule base expert system with activation rate and optimize the initial confidence rule base expert system; Through the optimized expert system of confidence rule base, the pipeline leakage of LNG terminal is evaluated, and the evaluation report is obtained. The method has the advantages that the concept of activation rate is used, and the rules which are never activated or are not activated enough can be trimmed in the optimization process. Even if there is a complete data set and all the rules are activated, the activation rate can be used in the parallel optimization process of BRB expert system, and effectively solve the problem of BRB combination explosion. It can make full use of quantitative data and improve the reliability of results without destroying the original explanation provided by experts. Collect pipeline flow and pressure data Establish BRB expert system BRB Expert System with Activation Ratej Evaluation result Figure 1

    • The embodiments of the present invention relate to the electronic communication field, and especially relate to a method, equipment and communication system for a mobile terminal accessing wireless network. The method of the embodiments in the present invention comprises: the mobile terminal sends a user identification of said mobile terminal to a Femtocell through Near Field Communication (NFC) when the mobile terminal closes to the Femtocell and enters the NFC range of the Femtocell and the mobile terminal; wherein, said mobile terminal and said Femetocell both support NFC (11); the Femtocell forwards the received user identification of the mobile terminal to a server (12); after having added the received user identification of the mobile terminal to the Femtocell access user list, the server transmits an access success notice to the mobile terminal (13); after having received the access success notice transmitted by the server, the mobile terminal accesses a wireless network using the Femtocell (14). In the method, equipment and communication system provided by the embodiments of the present invention, because the user identification of said mobile terminal is transmitted by the mobile terminal through NFC to the Femtocell, and forwarded to the server by the Femtocell, the server finishes updating the access user list of the Femtocell, the mobile uses the Femtocell to access the wireless network, the course for the user contacting the administrators of the provider by phone to update the Femtocell access user list is omitted, thus the wasting time is reduced and the fault that manual operation may result in is avoided. So the problem of the operation time being long, the operation course being complex, and error ratio being high for accessing can be solved. Therefore, the method, equipment and communication system provided by the embodiments of the present invention can provide a simple, fast and exact method for updating a list, consequently the mobile terminal can quickly access the wireless network.
    • 本发明的实施例涉及电子通信领域,特别涉及用于接入无线网络的移动终端的方法,设备和通信系统。 本发明实施例的方法包括:当移动终端关闭毫微微蜂窝并进入毫微微蜂窝的NFC范围时,移动终端通过近场通信(NFC)向毫微微小区发送所述移动终端的用户标识,并且 移动终端; 其中,所述移动终端和所述Femetocell都支持NFC(11); 毫微微小区将接收到的移动终端的用户标识转发到服务器(12); 在将接收到的移动终端的用户标识添加到毫微微蜂窝接入用户列表之后,服务器向移动终端发送访问成功通知(13); 在接收到由服务器发送的访问成功通知之后,移动终端使用毫微微蜂窝(14)访问无线网络。 在由本发明的实施例提供的方法,设备和通信系统中,由于移动终端的用户标识由移动终端通过NFC发送到毫微微蜂窝,并由毫微微蜂窝小区转发到服务器,服务器完成更新 毫微微蜂窝的接入用户列表,移动台使用毫微微蜂窝基站接入无线网络,通过电话与供应商的管理员联系以更新毫微微蜂窝接入用户列表的过程被省略,从而浪费时间减少, 可以避免手动操作导致的故障。 因此,操作时间长,操作过程复杂,访问错误率高等问题可以解决。 因此,由本发明的实施例提供的方法,设备和通信系统可以提供用于更新列表的简单,快速和精确的方法,因此移动终端可以快速地访问无线网络。
