Design And Realization Of The Remote Control Locks Based On Mobile Base Stations

With the development of mobile communication, mobile communication networks are constantly expanding in scale, mobile communication operators managed by multiplying the number of mobile base stations. The completion of the network in order to better protect and engineering tasks, operators began to introduce a large number of equipment and project outsourcing and peacekeeping. Along with the construction team and the peacekeeping contingent ever-increasing number of each team may need to have ready access to a different base stations to work. At this time, the base station locks become effective control and management of the operators have to consider the issue, it is necessary to ensure safety but also facilitate management, the locks at the same time, not because of cumbersome administrative procedures affecting the efficiency of base station and maintenance base Station fault handling time.This article is to address this issue, from the current mobile operators'status of the network, making full use of existing network resources and the design of the remote control door locks base station management system.The system is to fully utilize the advantages of a GSM base station in the external alarm monitoring, and the combination of network management platform development. Not only improve operability of the system in operation and reliability, but also greatly reduce system investment, cost savings. The system not only uses external base station alarm monitoring function of the input switching, and the development of the use of the output switch.This paper Motorola Horizon base stations as an example of the system on the specific method, the system controlled by the network management, remote doorbell, drive control circuit and electronic door locks application form four parts. Wireless network management can be effectively locks on the base stations of remote management and the competence of management into the base station, arrived confirmed that the visit statistics. Management control software based on Delphi + SQL Server platform development, can achieve authorized management, alarm rang the doorbell of inquiries, open operation, statistical analysis, and other functions. Through its authority to open the door to strictly control the operation and to ensure the accuracy door.Remote doorbell warning based on the development of the external environment base stations, base station can be the doorbell information will be reflected in network management control software, mainly for confirmation that the applicant has reached open base station and to guarantee the accuracy to open the door.Control circuit driven primarily by four 555-timer component can be divided into control of the electronic control and power locks part of the drive. Control of the three 555-timer component, mainly completion of the identification and control signal filtering. Electronic lock-driven in part by a 555 timer circuit and related components, mainly in the open signal recognition provided under the premise of opening the door drive voltage. Power in part by a switching power supply and a bridge circuit component, switching power supply in the base stations environment to achieve the -48 VDC to +12 VDC conversion, the need to provide 10 W output power, the role of bridge circuits to prevent power at the wrong circuit damage.Electronic door locks using Zhejiang HongTai Electronic locks NZ56, which can be electronically controlled lock, key or manually opened. The use of electronic control voltage 9-12 V, control current 1.5-3 A, the smallest unlock power of 10 W. Electricity form of intermittent electricity, sustained telegram time should be less than eight seconds, time can unlock for 12 V voltage continuous 0.5 seconds.Facts have proved that the use of GSM base station itself external warning system can be developed to achieve low cost, high stability of the remote control functions, which can save maintenance costs and improve the efficiency of maintenance work to upgrade the network management level.According to this design, the system of four-output switching to the use of all, if we use them all the way as a trigger coding, and the other three routes in control coding at least eight groups control commands. As long as the development of the corresponding control circuits and equipment interface circuit can be achieved on the base station's remote control equipment, such as air down-control opening and closing of raising and lowering the temperature settings, base stations opened and closed burglar alarm has reached such purpose.I believed that with the promotion of this area, the base station equipment manufacturer will be directly integrated into the functions of the corresponding base station equipment, so we can further reduce costs, but also better guarantee system compatibility and stability.
