Power module 14 provides the energy of work for automatic each module of walking arrangement 2, and it comprises chargeable power brick and the charging terminal that is connected with power brick.Charging terminal be suitable for charging station 4 on power supply terminal matched, to be connected on the external power source, be the power brick makeup energy.
Energy detection unit 18 connects power module and control module, also will represent that the signal of this energy level sends to control module 10 for detection of the energy level of the power brick in the power module.In the present embodiment, energy detection unit 18 detects the energy level of power brick by the voltage that detects power brick, be that energy detection unit 18 is the voltage detecting circuit of power brick, after it detects the magnitude of voltage of power brick, will represent that this voltage value signal sends to control module 10.Certainly, energy detection unit 18 also can adopt other direct or indirect modes to detect the energy level of power brick, the round-about way for example energy of testing duration prediction battery consumption is judged energy level etc., the various specific implementation forms of the energy detection unit of power brick are that those skilled in the art is known, are not described in detail at this.
One of the common composition of the pilot signal transmitter unit of pilot signal sensing unit 20 and automatic walking arrangement 2 outsides returns guidance system, is used for guiding automatic walking arrangement 2 to return charging station 4.
In the present embodiment, the pilot signal transmitter unit is specially an electric signal generator, and the charging guide line 6 that connects this electric signal generator, electric signal generator sends electric signal I on charging guide line 6, as the pilot signal of the automatic walking arrangement 2 of guiding to the charging station walking, this signal generator preferably is integrated in the charging station 4.Pilot signal sensing unit 20 is specially one or more inductance that are positioned on the automatic walking arrangement 2.Carry vicissitudinous current signal I on the charging guide line 6, it can produce the corresponding magnetic field that changes in the space around, and inductance by the variation magnetic field in the inductive spacing signal of induction charging guide line 6, and the signal of sensing passed to control module 10.Control module 10 is analyzed each feature of the signal of sensing, as the sensitive time, and the signal power, the sigtnal interval etc., judge automatic walking arrangement 2 relative position of charging guide line 6 relatively, distance is far and near.Like this, when needs returned, control module 10 sent instruction to walking module 12 according to the information that obtains, and made it drive automatic walking arrangement 2 and drove near the charging guide line 6 or the top of charging guide line 6, and then return charging station 4 along charging guide line 6.
Returning guidance system can also have other implementation.The pilot signal transmitter unit can be ultrasonic transmission device, and pilot signal sensing unit 20 can be the ultrasonic sensing device of correspondence, returns guidance system by the position of ultrasound wave location charging station 4, and guides automatic walking arrangement 2 to return charging station 4.The pilot signal transmitter unit can also be infrared transmitting device, and pilot signal sensing unit 20 can be the infrared induction device of correspondence, returns guidance system by the position of infrared ray location charging station 4, and guides automatic walking arrangement 2 to return charging station 4.
Under the common cooperation of the above various piece of introducing, the present invention by following described flow process in other words method realize returning charging, and return power brick in the charging process and cross and put protection.
With reference to Fig. 3, first kind of workflow of the present invention is particularly suited for recurrence charging judgement, execution and the power brick protection in the work, yet also can be applied in recurrence charging judgement, execution and power brick protection that start namely starts first.
In initial step S0, walking arrangement 2 is started shooting or is being worked automatically.
Enter step S2, control module 10 is by the energy level of energy detection unit 18 monitoring power brick.As previously mentioned, in the present embodiment, energy detection unit detects the power brick voltage of the energy level that has represented power brick, and sends it to control module.
Subsequently, in step S4, control module 10 judges that whether the energy level of power brick is greater than a default energy level.Should be pre-stored in the storer 24 of control module 10 by default energy level, the processor 22 of control module 10 should preset energy level and detected power brick energy level compares, if the energy level of power brick is greater than described default energy level, then get back to step S0, automatically walking arrangement 2 works on, and does not carry out other actions; Otherwise, if the energy level of power brick is not more than described default energy level, then entering step S6, startup makes automatic walking arrangement return the action of charging station.In present embodiment, because the energy level of power brick uses the voltage of power brick to represent, storage is a predeterminated voltage value in the storer 24, and processor 22 also passes through to compare the magnitude of voltage of power brick and the magnitude relationship of described predeterminated voltage value, judges the magnitude relationship of default energy level and detected power brick energy level.In addition, though in the present embodiment, flow process enters step S6 when the energy level of power brick equals to preset energy level, and this moment, flow process also was feasible if return step S2.
After control module 10 judges that the energy level of power brick is lower than default energy level, for conserve energy, in regression process, walking arrangement 2 operation of module 16 that quits work usually automatically.
After entering step S6, walking arrangement 2 starts the recurrence action automatically, namely begins to return charging station 4.Be step S8 after the step S6, walking arrangement is set a Preset Time length automatically, and picks up counting when startup returns action.Though step S6 is before step S8 in this flow process, those skilled in the art can understand step S6 and the not strict sequencing of step S8, and it can exchanging order, also can be considered to simultaneous.
Described Preset Time length was one and prestores and be stored in the fixed value of storer 22, as 20 minutes.In step S8, processor 22 reads this Preset Time length from storer 24, and instruction timer 26 picks up counting according to this Preset Time length.
In the present embodiment, as long as the energy level of power brick is less than or equal to default energy level, and no matter how many differences between this energy level and the default energy level is, Preset Time length all is certain.Yet in optional other schemes, Preset Time length also can be the value of a variation, and control module 10 can be set described Preset Time length according to the power brick energy level that monitors.Concrete, control module can be calculated this Preset Time length according to the difference size between detected energy level and the default energy level, and perhaps direct energy level according to power brick calculates this Preset Time length, and the two does not have essential distinction.In the present embodiment, because the energy level of power brick uses the voltage of power brick to represent, therefore, in fact control module 10 can be set described Preset Time length according to the magnitude of voltage of power brick, and concrete meeting is set this Preset Time length according to the difference size between detected magnitude of voltage and the predeterminated voltage value.For example, if detected power brick magnitude of voltage is 22v, and the predeterminated voltage value is 23v, and then Preset Time length is 20 minutes, and if detected power brick magnitude of voltage is 21v, then Preset Time length should be 18 minutes mutually, and is like that.Expect that easily Preset Time length and detected the magnitude of voltage corresponding relation of aforesaid difference in other words can be calculated by a formula, also can directly be set by a table of comparisons that is stored in advance in the storer 22.
Start after the recurrence action, walking arrangement 2 enters step S10 automatically, namely carries out to return and moves, and returns charging station.Automatically walking arrangement 2 is sought and the relevant pilot signal in charging station 4 positions by pilot signal sensing unit 20, and walks to charging station 4 according to pilot signal.Foregoing, the field signal of pilot signal sensing unit 20 by being produced by the electric signal on the charging guide line 6 around the induction to 6 walkings of charging guide line, walked towards charging station along charging guide line 6 subsequently.
Behind execution in step S10, control module 10 judges whether automatic walking arrangement 2 successfully returns charging station 4, be specially judge automatic walking arrangement 2 charging terminal whether with the power supply terminal of charging station 4 to connecting.Usually, whether this judgement has received outside voltage on the described charging terminal or signal is realized by monitoring, yet this judgement also can be carried out as other modes such as position, crash sensors by other.If judged result is for being, walking arrangement 2 has returned charging station 4 automatically, then enters step S14, and the automatic walking arrangement 2 of control module 10 controls stops walking, and begins to charge.If judged result then enters step S16 for not.
Step S16 judges whether Preset Time length arrives.If the result that step 16 is judged then returns step S10 and continues to carry out the action that returns charging station for not.If judged result is for being, Preset Time length arrives, and then enters step S18, and automatic walking arrangement enters the state that stops to walk.Be specially by control module 10 control walking module and quit work.
In first kind of workflow, no matter automatically walking arrangement 2 whether success return charging station 4, it all is in the state that stops to walk after Preset Time length.That is, if walking arrangement 2 has successfully returned charging station 4 in Preset Time length automatically, then it can be in the state that stops to walk and charge in charging station 4; If walking arrangement 2 has arrived in Preset Time length and still successfully do not returned charging station automatically, it also can be in the state that stops to walk.Such workflow has avoided automatic walking arrangement 2 in the time can't returning smoothly, still constantly seeks charging station 4, puts damage and cause power brick to be crossed.
Preferably, when being, control module 10 is also controlled automatic walking arrangement 2 and is sent a charging alerting signal, needs artificial assistance to return charging station 4 to remind the automatic walking arrangement 2 of user in the judged result of step S16.This charging alerting signal can be the graph text information on the display panel that is presented at automatic walking arrangement 2, also can be special alarm sound signal, can also be for long distance wireless be sent to information on other equipment of user, as send to short message on user's mobile phone or other prompting messages etc. by telephone network.
By aforesaid first kind of workflow, walking arrangement 2 can be in start automatically, and the energy level according to power brick in perhaps working starts recurrence in good time, and in regression process power brick is carried out putting protection.
Introduce second kind of workflow of the present invention below in conjunction with Fig. 4.In second kind of workflow, the two kinds of situations of starting shooting and work are distinguished to be come, the judgement that whether returns at separately concrete situation and the protection of power brick.Second kind of working method is particularly suited for automatic walking arrangement 2 and storing longer a period of time, and power brick is because of after self discharge causes voltage significantly to reduce, again Kai Ji situation.
At initial step S1, automatically walking arrangement 2 starts are namely closed or dormant state returns to opening from outage.Enter step S3 subsequently, energy detection unit 18 detects the zero energy level of power brick, and sends it to control module 10.
The zero energy level of power brick can not detect when the main power consumption part walking module 12 of automatic walking arrangement 2 and operational module 16 are worked as yet, but in the present embodiment, owing to be the energy level that detects power brick by the mode of surveying voltage, the magnitude of voltage virtual height of power brick in order to prevent from not working, walking arrangement 2 detects the zero energy level of power brick under work, the normally loaded situation of machine band automatically.Concrete, walking arrangement 2 at first starts walking module 12 and 16 several seconds of operational module after start automatically, detects the magnitude of voltage of power brick then and sends to control module 10.
After control module 10 received the signal of the zero energy level that represents power brick, execution in step S5 judged that whether the energy level of power brick is greater than one first default energy level.If the zero energy level of power brick then enters step S9 greater than described default energy level, control automatic walking arrangement 2 by control module and carry out work, for example drive walking and carry out preset task by operational module 16 by walking module 12; Otherwise, if the zero energy level of power brick is not more than the first default energy level, then enter step S7, whether the zero energy level that continues to judge power brick is greater than one second default energy level, and this second default energy level is less than the first default energy level.
If the judged result of step S7 is for denying, the zero energy level of power brick is not more than the second default energy level, then flow process jumps to step 27, and the automatic walking arrangement of control module 10 controls enters the state that stops to walk, and this moment is the common task that also can not carry out other of walking arrangement automatically.If the judged result of step S7 is for being, the zero energy level of power brick then changes step S15 over to greater than the second default energy level, and walking arrangement 2 starts to return and moves automatically.
In step S5 and step S7, concrete deterministic process and first working method of zero energy size are similar.Because what energy detection unit detected is the voltage of power brick, so the zero energy level of power brick, the first default energy level and the second default energy level all use the initial voltage value of corresponding power brick, the first predeterminated voltage value, the second predeterminated voltage value is represented.This first predeterminated voltage value, the second predeterminated voltage value are pre-stored in the storer 24 of control module 10, the processor 22 of control module 10 is judged the zero energy level of power brick and the relation of the first predeterminated voltage value or the second predeterminated voltage value by the initial voltage value of power brick and the first predeterminated voltage value or the second predeterminated voltage value are compared.
By top flow setting, automatically walking arrangement 2 zero energy level according to power brick after start has three kinds of subsequent actions: if the zero energy level of power brick is greater than the first default energy level, represent the zero energy abundance of power brick, then walking arrangement 2 is carried out first kind of subsequent action automatically, entering step S9 normally starts, default task or other instructions that receives are namely carried out in automatic walking arrangement 2 execution works of control module 10 instructions; If the zero energy level of power brick is between the first default energy level and the second default energy level, namely preset energy level less than the first default energy level greater than second, represent the zero energy deficiency of power brick, need makeup energy, then walking arrangement 2 is carried out second kind of subsequent action automatically, enters step S15 and carries out the action that returns charging station 4; If the zero energy level of power brick is less than or equal to the second default energy level, represent the zero energy wretched insufficiency of power brick, the action that is not suitable for execution work and returns charging station 4, thereby walking arrangement 2 is carried out the third subsequent action automatically, execution in step S27, the automatic walking arrangement 2 of control module 10 instructions enters the state that stops to walk.Can effectively avoid the power brick energy to cross like this and start recurrence when hanging down, cause power brick to be crossed and put damage.
If carry out first kind of subsequent action, then walking arrangement 2 is to change step S15 over to from the S5 step automatically, and the follow-up flow process by S15 proceeds to step S27 subsequently.From entering step S9, up to step S27, workflow and aforementioned first kind of workflow basically identical of automatic walking arrangement 2.
After the step S9, automatically walking arrangement 2 enters step S11, the energy level of monitoring power brick, judge that in step S13 whether the energy level of power brick is greater than the 3rd default energy level, the 3rd default energy level is preset energy level smaller or equal to first, and greater than the second default energy level; The 3rd default energy level represents by magnitude of voltage that equally prestoring is stored in the storer 24.If the judged result of step S13 is then returned step S9 continuation execution work for being, if judged result then enters step S15 and starts the recurrence action for not; In step S17, walking arrangement 2 arranges a Preset Time length automatically, and picks up counting from starting to return to move by timer 26; Behind the step S17, flow process enters S19, and walking arrangement is carried out and returned action automatically.After the step S19, control module 10 judges in step S21 whether automatic walking arrangement 2 has returned charging station 2, if judged result for being, then enters step S23, walking arrangement 2 stops walking and charges automatically; If judged result then enters step 25 for not, judge whether that then execution recurrence action has reached Preset Time length, if the judged result of step 25 is then returned step S19 continuation execution and returned action for not; If the judged result of step 25 then enters step S27 for being, walking arrangement 2 enters the state that stops to walk automatically.
If carry out second kind of subsequent action, then walking arrangement 2 is to change step S15 over to from the S7 step automatically, and the follow-up flow process by S15 proceeds to step S27 subsequently.In this case, it is especially favourable according to the zero energy level of detected power brick in the S3 step or initial voltage value described Preset Time length being set.Because in first kind of workflow, if detect the power brick energy in the course of the work, the energy level of power brick reduces gradually from height point, automatically walking arrangement 2 starts when returning, the energy level of power brick is generally equal to or a little less than default energy level, therefore, it is feasible a fixing Preset Time length being set.Yet, describe as second kind of workflow, the flow process that begins from boot action, power brick is because self discharge, it is a lot of that energy level may be lower than the first default energy level, at this moment, can set the default working time according to actual time that can also safe operation of power brick according to the zero energy level of power brick or initial voltage value, put damage thereby avoid power brick to cross.
From step S15, automatically the workflow of walking arrangement 2 is identical from the flow process that step S15 begins with first kind of subsequent action, namely starts to return, and sets a Preset Time length and pick up counting, if this Preset Time length has arrived, then enter the state that stops to walk.Idiographic flow does not repeat them here.
Similar with first kind of workflow, in the recurrence related procedure of first kind of subsequent action and second kind of subsequent action, no matter automatically walking arrangement 2 whether success return charging station 4, it all is in the state that stops to walk after Preset Time length.That is, if walking arrangement 2 has successfully returned charging station 4 in Preset Time length automatically, then it can be in the state that stops to walk and charge in charging station 4; If walking arrangement 2 has arrived in Preset Time length and still successfully do not returned charging station automatically, it also can be in the state that stops to walk.Such workflow has avoided automatic walking arrangement 2 in the time can't returning smoothly, still constantly seeks charging station 4, puts damage and cause power brick to be crossed.
If carry out the third subsequent action, walking arrangement 2 directly changes step S27 over to automatically, enters the state that stops to walk, and waits for that the user manually assists it to charge.Similar with aforesaid first kind of workflow, walking arrangement 2 can also send the charging alerting signal automatically.
By two kinds of workflows recited above, automatic walking arrangement 2 of the present invention can return the charging station charging automatically when energy shortage, and the mistake of power brick is put damage in having avoided simultaneously returning.
