Described intelligent control unit adopts microcontroller, described microcontroller adopts commercially available 32 bit CPUs based on ARM9, described CPU is handheld terminal and Embedded Application exploitation specially, have low in energy consumption, scalability is good, directly drive with CMOS camera, can the advantage such as image procossing and identification be carried out; In order to the low-power consumption of keeping system, the embedded system peripheral hardware of described intelligent control unit only retains Bluetooth and smart machine communication, and remaining peripheral hardware does not retain, as LCD, keyboard all do not use.
Described power subsystem has lithium ion battery and solar cell, and power subsystem adopts commercially available bq24070 power management chip; Lithium ion battery adopts the battery of 3.7V1000mAh; Solar cell is in series by the monocrystalline silicon lamination solar panels of four 2.5W, 1.5V, and output voltage is 6V; The appearance and size of power subsystem is 210*82*2.3mm, and on the base that power subsystem is locked with being arranged on electric vehicle position, skin is equipped with tempered glass, in order to protect cell managing device.When solar cell receives illumination, the electric energy of generation is supplied to system on the one hand, if having unnecessary, is then supplied to lithium ion cell charging, locks electric energy all the time with guaranteeing intelligent car position sufficient; As parked for a long time due to vehicle, locking with making intelligent car position and cannot charge for a long time, then after this electric vehicle position ground lock is in down state; After vehicle leaves, when solar cell can provide abundant electric energy, electric vehicle position ground lock rises, thus can not affect parking of vehicle.
Solar cell comprises a P-N junction, and luminous energy (photon) makes electronics and hole reconfigure at this, thus generation current.The electric current generated is directly proportional to the quantity of illumination that solar cell receives.
Described image identification system adopts commercially available image identification system, has CMOS camera and image recognition program, and CMOS camera locks end with being arranged on electric vehicle position; The image of car plate is comprised by CMOS camera acquisition vehicle, image recognition program is analyzed the image size got and bit depth, image is converted to 1 bit depth, and carry out denoising, smoothing processing, take out the rectangular area of effective number plate information, by image stretch to fixed size, the image of outputting standard, by carrying out character recognition to standard picture, take out effective number information.

The intelligent car position ground lock of view-based access control model Internet of Things is locked with can utilizing existing electric vehicle position, by Serve Motor Control mobile lifting support, thus controls the rise and fall of electric vehicle position ground lock.
Fig. 3 is the circuit that solar energy electroplax is applied to lithium ion cell charging, bq24070 monolithic lithium ion is utilized to charge and system power supply path management chip, the maximization of solar panel electric power can be realized, employ MOSFET Q2 and come regulating cell charging current, charging voltage or system bus voltages.
In Fig. 3, the maximum output voltage (VOC) that solar panel SUNDC provides is usually between 5.5V ~ 6.0V.Because this voltage is lower than predefined 6V Drazin inverse voltage, therefore MOSFET Q1 opens completely.If load FZ(system and battery charger) needed for total current exceed the output current that solar cell determines according to the quantity of illumination, so the output voltage of solar panel SUNDC will reduce, thus reduce output voltage (VOUT).When VOUT is down to VDPPM, charging current reduces.As VDPPM arranges the position at this moment will be operated near MPP near MPP, solar panel SUNDC.By suitably programming to VDPPM, making it reach certain value, guaranteeing that VOUT is minimally 4.5V, thus realizing above-mentioned purpose.
Assuming that the pressure drop on MOSFET Q1 is 300mV, the pressure drop on so each unit will equal 436mV, and this will maximize the power stage of solar panel.In Fig. 2, when power output is close to MPP, its curve is more smooth, can sharply decline subsequently, therefore VDPPM preferably establishes slightly higher by we, and does not establish lower slightly, and this will reduce as far as possible because operating voltage arranges improper and produce harmful effect to power output.Even if if when battery charge is down to zero, solar panel can electric power be also not enough to system power supply, so MOSFET Q 2 will open completely, and VOUT is just down to below cell voltage VBAT value, and the electric current that battery can provide solar panel not provide.Electric power management circuit manages to reach steady-state condition, makes the electric power needed for system acquisition, and charges the battery by dump power, like this, just can maximize the electric power of solar panel, and improve the reliability of system.
