Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1 ~ 3, a kind of wireless type Battery Discharging Device, comprise power module, main control unit, display and operational module, load discharge module, load switching mechanism, current transformer, voltage sensor, described load discharge module comprises four ohmic loads and PWM load that are arranged in parallel, described load discharge module is connected with main control unit, and described load switching mechanism is connected with described ohmic load, described main control unit is by central processing module, analog input and output module, number connect test module, data memory module and network communication module composition, main control unit is PLC or single-chip microcomputer, PLC is preferably Micro830, single-chip microcomputer is preferably ARM9, main control unit passes through WLAN (wireless local area network), ICP/IP protocol or other communications protocol is adopted to be connected with wireless router, wireless router is connected to maintenance remote terminal and control movable termination, described remote terminal is mobile phone, panel computer or PC PC, described movable termination is mobile phone or panel computer, main control unit is also connected with graphic control panel and alarm.
During work, as the mobile phone of remote terminal, panel computer and PC PC and as the mobile phone of movable termination and panel computer, APP software is all installed, by utilizing WLAN (wireless local area network) to be connected with wireless router, control unit is also connected with wireless router by the network communication module arranged in it; The mobile phone of movable termination also can be directly connected with control unit by the network communication module in control unit with panel computer.
Wherein, described main control unit monitors battery discharging process in real time by current transformer and voltage sensor, display and operational module, main control unit control described ohmic load conducting number and and control PWM load realize the control of discharge process.Certainly, in practical application, 3 ohmic loads of not connecting with PWM be arranged in parallel can be the form of resistance box or other forms of pure resistor load, as long as realize of the present utility model in parallel with PWM load.
As one of control circuit that Fig. 2 is load switching mechanism of the present utility model, can according to total class of the size selective relay of load.Because main control unit can be selected to control according to the numerical value of discharging current, as long as meet load parallel relationship, just can effectively realize close to discharging current numerical value when load accesses, not enough discharging current part has been controlled by PWM
If Fig. 3 is pwm circuit figure of the present utility model.In Fig. 3, Q1, Q2 form a promotion circuit, meet the needs of discharge tube drive current and voltage.In the electric discharge device of the present embodiment, have employed 2 road pwm control circuits, wherein a road pwm control circuit is as stand-by state, when PWM controls the duty cycle signals of output 100%, this discharge circuit is in complete on-state, and its meaning equals relay access load, when exporting 0% duty cycle signals, this discharge circuit is in closed condition, and its meaning equals disconnecting consumers.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned execution mode, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
