In Fig. 1, there is the power supply of 3 tunnels：1st tunnel, solar energy take electricity, solar panels open-circuit voltage 5.5V, maximum power 0.15W. 2nd tunnel, 10 kilovolts of overhead transmission line CT take electricity.3rd tunnel, dry cell power supply.3 road electrical energy systems by 0.4 volt of pressure drop diode D2, D6, D7 are in parallel, after inputing to DC/DC converters voltage stabilizing supply one CPU, that is, CPU1 into 3.3V.There are 3 electronic switches in system K1, K2, K3, its on off operating mode are controlled by the first CPU, and the first CPU completes power management function.The electric energy of two CPU, that is, CPU2 Supply is by switch K3 controls.
Consideration system works in the worst cases, i.e. dry cell electric energy depletes, and is also taken on high-voltage line less than electricity, long-term cloudy Rain, causes rechargeable lithium battery electric energy also to deplete, system-down.Quickly system is guided to work in this case, Zhi Nengyi Charge by solar energy-electric energy system.After rechargeable battery lithium battery can deplete, if its for 5000mA capacity to again It is full of, it can be assumed that it is an energy small black holes, and input terminal electric energy is pulled away by it entirely, it is necessary to 48 in the case of sunny ~72 complete charging when small.In lithium battery charging process, since output voltage rising is slower, cause system a very long time not It can work, in order to avoid this situation occurs, it is necessary to which a bootstrap power supply, completes system Charge Management, the first super capacitor C1 Exactly complete this function.
When system capacity depletes state, system-down.When solar energy is sufficient, super capacitor C1 needs charging 12 minutes Left and right, voltage rise to 5V or so, after the second pressure drop diode D2, and the arrangement of DC/DC converters, export 3.3V voltages, Powering to CPU1, CPU1 is completed under low power consumpting state after starting, and first starts the measurement of its first collection signal input part A/D1, To judge current energy state, when electric energy is sufficient, CPU1 controls its PB5 pin high level, switch K1 conductings, while CPU1 is controlled Its PB4 pin high level is made, the collection of energy and charging management chip TPS62736 of lithium battery charging is opened for, starts to charge up, Collection of energy completes Charge Management with charging management chip TPS62736.In charging process, CPU1 monitors its A/D1 pin electricity Level values, when the level value of A/D1 pins is less than the magnitude of voltage set, shut-off switchs K1, and the power supply of solar panel is directly defeated Go out and charge to the first super capacitor C1, be thusly-formed lithium battery and capacitance alternating charging process.
After CPU1, which detects A/D1 values, is more than the value of setting, switch K3 is opened, CPU2 is entered working status, and moment The change of A/D1 pin level values is monitored, to ensure the enough of energy.
It is connected between CPU1 and CPU2 by PB0, PB1 input and output pin.Define four shapes of PB0, PB1 pin of CPU1 State value：00th, 01,10,11,25%, 50%, 75%, 100% electricity is represented respectively., can be with after CPU2 knows current power state Decision enters low power consumpting state or full speed operation state.
Also it is connected between CPU1 and CPU2 by serial ports, CPU1 is by the level of measured A/D1, A/D2, A/D3, A/D4 Value sends CPU2 to by serial ports, these values are passed through connected wireless communication module and uploaded onto the server end by CPU2.These Value reflects electric power system energy state completely.
When CT takes electricity to disclosure satisfy that CPU1 starts on line, and another two-way cannot power：After CPU1 starts, it will be detected The value of A/D2, A/D3 pin, if A/D2 values are higher than the value of certain setting, illustrate that lithium electric system does not deplete, does not form black hole, At this moment CPU1 opens switch K2, charges in Qu electricity to lithium battery；If A/D2 values are less than the value of some setting, CPU1 will be turned off K2 is switched, only retains system power supply function.
CPU1 is by measuring the value of A/D2, to judge current main energetic rank, and notifies CPU2 to be in 00 or 01 or 10 Or 11 state.
