The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings 2- Fig. 9 describe the embodiment of the present invention for autocrane extended-range dynamical system and its Control method.
Fig. 2 is the structural block diagram of the extended-range dynamical system according to an embodiment of the present invention for autocrane.
As shown in Fig. 2, the extended-range dynamical system 100 for being used for autocrane includes: first the 1, second electricity of motor Motivation 2, power battery 3, battery manager 4, distance increasing unit 5 and controller 6.
Wherein, the first motor 1 is for driving autocrane 1000 to travel;Second motor 2 is for driving automobile to rise The hoist hydraulic system of heavy-duty machine 1000 works;Power battery 3 to the first motor 1 and the second motor 2 for powering respectively;Electricity Pool manager 4 is used to carry out power battery 3 charge and discharge control, and the electricity of detection power battery 3;Distance increasing unit 5 includes hair Motivation 51 and generator 52, engine 51 is for driving generator 52 to charge to power battery 3;Controller 6 is electric with first respectively Motivation 1, the second motor 2, battery manager 4 are connected with engine 51, for obtaining the current state of autocrane 1000, And first motor 1, the second motor 2 and engine 51 are controlled according to the electricity of current state and power battery 3.
In one embodiment, controller 6 is particularly used in: power battery 3 electricity less than the first preset value, and vapour When vehicle crane 1000 is in driving status, control the first motor stall so that autocrane 1000 stop traveling, And stop control engine 51 when driving in autocrane 1000 and start, to drive generator 52 to charge to power battery 3;Or Person power battery 3 electricity less than the first preset value, and when autocrane 1000 is in lifting state, control second is electronic Machine stops working so that autocrane 1000 stops lifting work, and controls when autocrane 1000 stops lifting work Engine 51 starts, to drive generator 52 to charge to power battery 3, wherein lifting state and driving status mutual exclusion.
In one example, controller 6 specifically can also be used in: it is default to be greater than or equal to first in the electricity of power battery 3 Value, and when less than the second preset value, control engine 51 starts, and to drive generator 52 to give the charging of power battery 3, makes power electric 2 continued power of the first motor 1 or the second motor is persistently given in pond 3, so that the first motor 1 drives autocrane 1000 Traveling, alternatively, so that the second motor 2 determines the hoist hydraulic system work of autocrane 1000.
Further, controller 6 specifically can also be used in: when the electricity of power battery 3 is greater than the second preset value, control hair Motivation 51 is out of service, and when autocrane 1000 receives traveling request, establishes power battery 3 and the first motor 1 Between for electrical connection, and control the first motor 1 driving autocrane 1000 travel;Or the electricity in power battery 3 When greater than the second preset value, control engine 51 is out of service, and when autocrane receives lifting request, establishes power Between battery 3 and the second motor 2 for being electrically connected, and control the second motor 2 driving autocrane hoist hydraulic pressure system System work.
Specifically, battery manager 4 can real-time detection power battery 3 electricity, and be sent to controller 6, meanwhile, control Device 6 processed can obtain the current state of autocrane 1000 in real time, if the electricity of power battery 3 is said less than the first preset value Bright electricity at this time is extremely low, can not be continuously traveling or lifting work provides enough power, therefore, if autocrane at this time 1000 are in driving status, then controller 6 controls the first motor 1 and stops working so that autocrane 1000 stops traveling; If autocrane 1000 is in driving status at this time, controls the second motor 2 and stop working so that autocrane 1000 Stop lifting work;When autocrane 1000 stops traveling or stops lifting work, controller 6 controls engine 51 and opens It is dynamic, and then generator 52 is driven to charge to power battery 3, which is properly termed as shutting down power generation mode, operation signal such as Fig. 3 It is shown, until battery manager 4 detects that the electricity of power battery 3 reaches the first preset value.
It should be noted that controller 6 can control system 100 to move back when the electricity 3 of power battery reaches the first preset value Power generation mode is shut down out.As described above, power battery 3 electricity less than first with preset value when, controller 6 may be got Crane 1000 is in driving status or lifting working condition, it is to be understood that crane 1000 is also possible in shutdown shape Less than the first preset value, and when crane 1000 is in shutdown status, controller 6 also be can control for state, the i.e. electricity of power battery 3 It, which enters, shuts down power generation mode (only having lacked control to stop traveling and stop lifting work This move).
Reach the first preset value in the electricity of power battery 3, and when less than the second preset value, illustrate that electricity is lower at this time, It is not enough to provide the first motor 1 or the second motor 2 driving traveling or the power of hoist hydraulic system work completely, therefore, If controller 6 gets crane 1000 and is in driving status or lifting working condition at this time, the starting of engine 51 is controlled, into And generator 52 is driven to charge to power battery 3, so that the first motor 1 continues that autocrane 1000 is driven to travel, or Second motor 2 continues to drive the hoist hydraulic system work of autocrane 1000, and then maintains autocrane 1000 Continue to travel or lift work, guarantees that crane 1000 can be long lasting for travelling or lifting work, which can be described as increasing Journey mode, operation signal are as shown in Figure 4.
In this example, if the electricity in power battery 3 reaches the first preset value, and when less than the second preset value, automobile Crane 1000 is in shutdown status, then can equally enter and increase journey mode, i.e., controller 6 can receive traveling request or lifting work Request, and (traveling or lifting work) is controlled accordingly.
When the electricity of power battery 3 is greater than the second preset value, illustrate that electricity is sufficient at this time, it is sufficient to provide autocrane 1000 pure motor drivings or the power of pure electric vehicle lifting work, thus it is out of service to control engine 51, that is to say, that vapour at this time Vehicle crane 1000 can carry out pure motor driving or pure electric vehicle lifting work, and when controller 6 receives traveling request, establish Between power battery 3 and the first motor 1 for being electrically connected, and control the first motor 1 driving autocrane 1000 travel, The process can be described as pure motor driving mode, and operation signal is as shown in Fig. 5 (a), alternatively, controller 6 is asked receiving lifting When asking, establish between power battery 3 and the second motor 2 for being electrically connected, and control the second motor 2 drive autocrane 1000 hoist hydraulic system work, the process can be described as pure electric vehicle lifting operating mode, and operation signal is as shown in Fig. 5 (b).
It is understood that autocrane 1000 has been in driving status or lifting shape after increasing journey mode State, i.e., it is out of service only to control engine 51 at this time, so that the driving dynamics of autocrane 1000 or lifting work Power is provided by power battery 3 completely, i.e. progress pure motor driving mode or pure electric vehicle lifts operating mode.
In this example, when autocrane 1000 is in pure motor driving state or pure electric vehicle lifting working condition, It can be by the electricity of 4 real-time detection power battery 3 of battery manager, to be carried out according to the current state of electricity and crane 1000 Corresponding control.
Preferably, engine 51 can be diesel engine, and power battery 3 can be lead storage battery, lithium battery or fuel Battery etc., voltage is generally 12V-72V.
Generally speaking, controller 6 connects according to the current state of the autocrane 1000 got and from battery manager 4 The electricity of the power battery 3 of receipts controls the first motor 1, the second motor 2 and engine 51, specifically: in electricity When extremely low and lower (namely not enough power supply), control engine 51 (diesel engine) starting, and then drive generator 52 It charges to power battery 3, to enter shutdown power generation mode when electricity is extremely low, enters when electricity is lower and increase journey mode;In electricity It when amount is sufficient, can control engine 51 out of service, and enter pure motor driving mode or pure electric vehicle lifting operating mode.
It is controlled as a result, according to the current state of the electricity of power battery and autocrane, only in power battery When not enough power supply, starting engine is power battery charging, compared to having been driven completely by engine or power battery Heavy-duty machine traveling or lifting, can reduce engine pollutant discharge amount, take into account energy conservation and environmental protection and long cruise duration, to make up The deficiency of pure electric automobile crane power system.
