Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
A kind of mobile base station stand-by power supply; Comprise master controller 1, cell detection system 2, a plurality of charging module 3 and a plurality of rechargeable battery 4, rechargeable battery 4 is connected the two ends of charging module 3, and master controller 1 is connected with cell detection system 2; Charging module 3 is connected with cell detection system 2; Charging module 3 is connected with the 220V power supply through charging control contactor 5, and master controller 1 is connected with charging control contactor 5, and DC/DC module 6 is connected with rechargeable battery 4; DC/DC module 6 is connected with rectification module 8 through diode 7, and rectification module 8 is connected with the 220V power supply through charging control contactor 5, and charging control contactor 5 is connected with master controller 1; Rectification module 8 is connected with master controller 1 through first voltage detection module 9; DC/DC module 6 is connected with master controller 1 through first voltage detection module 9; Master controller 1 is connected with rectification module 8 through second voltage detection module 10; Be provided with over device 11 between the rectification module 8 and second voltage detection module 10, over device 11 is connected with master controller 1; Master controller 1 is connected with shunt 13 through current detection module 12, and shunt 13 is connected with rechargeable battery 4, and shunt 13 is connected with DC/DC module 6, and shunt 13 is connected with second voltage detection module 10.Be connected with GPRS module 14 on the master controller 1.Be connected with normally closed switch 15 and antitheft indicator light 16 on the master controller 1.Rectification module 8 outputs are provided with three tunnel loads.
The operation principle explanation:
1: charging control contactor 5 receives master controller 1 indication; Charge through 3 pairs of rechargeable batteries 4 of charging module when closed; Can avoid the floating charge state of battery during unlatching, the next door+24V is the outside power supply that provides, and guarantees the 5 completion dependent instruction work of charging control contactor.2 of monomer voltage detection systems are to detect the state of each cell, judge battery status, when cell voltage surpasses 3.85V, then stop battery charge, simultaneously, when cell voltage during less than 2V, let battery stop discharge.
2:DC/DC module 6 is the direct currents that convert the direct current of the 48V of rechargeable battery 4 into 24V, supplies with master controller 1 and uses with charging control contactor 5.The function of diode is to prevent the battery reverse charge.
3: the function of master controller 1 then is the control centre of entire circuit, and individual module is judged, sends instruction simultaneously, to realize specific purpose.9 main voltages that detect battery pack of first voltage detection module on master controller 1 top are in time given master controller 1 with feedback information.
4: the current detection module 12 below the master controller 1 detects the discharging current of battery pack, in time gives master controller 1 with feedback information.GPRS then is a wireless communication module, realizes the exchange of master controller data and control centre's data.It is to carry out communication through 485 mode with master controller.11 of over devices are when monomer battery voltage is lower than 2V, in time cut off circuit, guarantee the safety of battery.
5: first voltage detection module 9 on rectification module 8 tops, its function mainly are to detect external power source through the voltage that rectification module 8 forms, and in time give master controller 1 with feedback information.Three tunnel loads are the main electric loadings of using, and its electricity consumption comes from two aspects, the one, and the electricity that directly forms through rectification module 8 from external power source AC220V, the 2nd, use the energy-storage battery group to store when externally not having electricity.When there was electricity the outside, AC220V began rechargeable battery set is charged, and AC220V carries out to load one, two, three electric energy being provided after the rectification simultaneously; When the outside does not have electricity, then in time start the energy-storage battery group load is supplied power.Certainly when cell voltage reduced to 2V, the stand-by power supply electric consumption finished, and fed back to control centre through master controller 1 with GPRS simultaneously, and purpose is artificially can take emergency measures.
