Embodiment
As shown in Figure 1; the utility model proposes a kind of intelligent adjustable DC power supply based on CAN, comprise intelligent monitored control module, display module, power supply management module, signal detection module, driving/protection module, inversion module, rectification filtering module, switch matrix.
Described display module, sends each monitoring point information by intelligent monitored control module by CAN and shows; Described power supply management module is a node of CAN, can the control command sent of real-time reception intelligent monitored control module and other information in the intelligent regulated power supply module of net, and by the input of place intelligence regulated power supply inside modules, the Data Control inversion module of output detections module feedback, realize intelligent charge management; Described signal detection module is made up of multiple test point, is distributed in the input/output terminal of system, inversion module output, also can adds node arbitrarily, and detection signal access charge control module, so that data are shared by CAN; Described driving/protection module is made up of two parts, and the IGBT module realized in inversion module drives and the overvoltage of regulated power supply module major loop, overcurrent protection; Described rectification filtering module is also divided into preposition and rearmounted two kinds, and preposition rectification filtering module is made up of electromagnetic interface filter, rectification filtering module, APFC module, rearmounted rectification filtering module by; Described switch matrix is used for the direct current after to three road rectifying and wave-filterings and exports and charging terminal arranges according to user or automatically chooses prioritization scheme and is configured, to reach the effect of energy-and time-economizing; Described intelligent monitored control module, is furnished with input through keyboard, user can be arranged system, intelligent monitored control module is by the power supply management model calling in CAN and display module, each intelligent regulated power supply module, each module builds a network by CAN, take intelligent monitored control module as master controller, optimize signal detection module topological structure, each module information is shared, unified coordination and management, reach the object of rapid reaction, efficient energy-saving, also constantly can add new node simultaneously, multiple intelligent regulated power supply module is provided, realizes charging in batches intelligent management.
After user connects electric terminal, by the size of current needed for the electrical appliance on each seat in the plane of input through keyboard of intelligent monitored control module, intelligent monitor system sends data to power supply management module, the data that power supply management module returns feedback according to test point 1 judge that whether input power is in allowed band, if input power overcurrent or overvoltage, then Control protection module deenergization and main circuit, if input power is in allowed band, then intelligent monitor system arranges the state of D.C. contactor in one side control switch module according to electric current, on the other hand by the three-phase IGBT in drived control inversion module, DC power supply after rectifying and wave-filtering is by obtaining the AC power of power adjustable after inversion module, three tunnel current-sharing electric currents are obtained again by three secondary winding transformer coils of transformer, switch module is arrived through corresponding rearmounted rectification filtering module, the state of switch module selects charging/powering mode according to charging management system.
Be illustrated in figure 2 the intelligent adjustable DC power extension multiple power module structure figure of the utility model based on CAN.Can see by figure, CAN can mount multiple intelligent regulated power supply module, the power of each intelligent regulated power supply module can be different, each intelligent regulated power supply module again can external multiple charging terminal, each charging terminal is controlled by switch matrix, carry out time sharing power supply, each module work state by intelligent monitor system unified management, and is shown in display module by all intelligent regulated power supply modules.As seen from Figure 2, the intelligent adjustable DC power supply based on CAN that the utility model realizes, the batch that well can realize the power consumption equipment of different capacity is powered or charges.
Be illustrated in figure 3 the intelligent adjustable DC power supply breaker in middle matrix principle schematic diagram of the utility model based on CAN.Can see by figure, switch is divided into 3 groups, and corresponding station is also just divided into 3 groups, is station 1.1,1.2 respectively ..., 1.m; Station 2.1,2.2 ..., 2.m; Station 3.1,3.2 ..., 3.m.Multiple powering mode is may be combined with out by the break-make of switch, three seats in the plane work simultaneously, and typical apply execution mode can be described below: when needs to storage battery carry out batch charge time, can by all storage battery to be charged access stations, after unit supply current is set, by power supply management module controls switch matrix, can realize at most often organizing an equal current charge of station, i.e. 3 equal current charges of station, as 1.1,2.1,3.1, now K switch 11, K211, K311; K12, K221, K321; K13, K231, K331 are closed.After detecting the charge in batteries determining often to organize corresponding station and completing, automatically switch with other storage batterys to be charged of group, as now can K311, K321, K331 be disconnected, closed K312, K322, K331.Charged storage battery can be replaced while charging, realize the charging of continuous batch.
The maximum power of each intelligent regulated power supply module is determined at the beginning of design, as the intelligent regulated power supply module of a 300V120A, by transformer secondary output winding trisection output current, obtain three tunnel 1 ~ 40A electric currents, again by the switching of switch matrix, can realize the time sharing power supply to m station, the size of m depends on the scale of switch matrix and the rated current of electric terminal.
When there being intelligent regulated power supply module to break down in system, power supply management module is by starting protection circuitry cuts primary input power supply, and information can be shown on screen by display module simultaneously, is convenient to unified management during batch charging.
CAN can adopt hot plug form arbitrarily to increase and decrease intelligent regulated power supply module, when to need the intelligent charging module increasing other power grades later, can directly access simply and easily; User can select the module capacity of increase according to the demand of electric terminal, realize cost optimization.Particularly when user is higher to emergent power reguirements, can increase spare module to nucleus module, when certain module breaks down, influential system does not normally work and system maintenance, realizes good emergency processing.
