Embodiment
Because bus Internet of Things peace control terminal device needs to difference in functionality module for power supply on multiple IP Camera and mainboard, but, IP Camera is different with the supply power voltage demand of difference in functionality module on mainboard, all directly can not be powered by vehicle power, so need the magnitude of voltage of vehicle power access access peace control terminal device after two-stage conversion circuit respectively.
For making the object of invention, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described in further detail.
Fig. 1 is power conversion structure chart.Peace control terminal provides 24V DC power supply by vehicle power, two-way 12V power supply is converted into after first order power conversion module, wherein a road directly powers to multiple cameras of peace control terminal, an other road 12V power supply is after the conversion circuit of the second level, and the magnitude of voltage being separately converted to multiple different numerical value is powered to each functional module of the mainboard of motive objects networking vehicular traffic peace control terminal and mainboard module.On mainboard, functional module comprises that USB interface is powered, audio video transmission interface is powered, ethernet module is powered, GPS module is powered, 4G module for power supply, SATA portable hard drive are powered, IO expansion interface is powered.
Fig. 2 is first order power-converting circuit figure, Fig. 3 is second level power-converting circuit figure.The circuit connection describing power conversion that these two figure are detailed respectively.It is the circuit diagram of 12V that Fig. 2 describes the photovoltaic conversion entered by vehicle power, and figure tri-describes second level power-converting circuit and becomes the circuit of the different magnitude of voltage of 7V, 3.7V, 3.3V, 5V, 2.5V, 1.8V, 1.5V, 1.2V to connect the photovoltaic conversion of 12V through chips such as TPS5430, TPS54331, TPS51200.First order conversion circuit be a kind of first by vehicle power access 24V DC power supply two panels TPS5430 power conversion chip be converted into the power supply with two-way 12V.Wherein a road 12V voltage powers to the multi-channel network camera of access peace control terminal.
Fig. 4 is the schematic diagram of second level power-converting circuit.Second level conversion circuit is that another road 12V voltage of transforming out using the first order is as input power, 8 power conversion chip TPS5430 and TPS5450 are utilized to transform out 7V, 3.7V, 3.3V, 5V, 2.5V, 1.8V, 1.5V, 1.2V magnitude of voltage, due to precision and the semaphore request of required magnitude of voltage, utilize other power conversion chip TPS54331 to export the magnitude of voltage of 1.0V, power conversion chip TPS51200 exports the magnitude of voltage of 1.5V simultaneously.
