Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
As shown in fig. 1 and fig. 2, the present embodiment discloses a nomadic wireless centralized power supply system, which is used for performing real-time charging management on a plurality of building robots in a building construction site, but not limited thereto, that is, the present embodiment may also perform real-time charging management on devices using a battery system in other fields. Specifically, the power supply system in the present embodiment includes several high-power remote wireless charging apparatuses 10, a power supply module 13, and a control platform.
The power module 13 is electrically connected to the wireless charging devices 10 to provide power to the wireless charging devices 10. The wireless charging devices 10 are distributed in the moving area of the equipment to be charged 2 in a net shape, and the wireless charging devices 10 are used for wirelessly charging the equipment to be charged 2 (such as a construction robot) entering the signal range of the wireless charging devices. Specifically, the wireless charging device 10 is preferably a 10-meter microwave wireless power transmitter.
The control platform comprises a control module 11 and a power distribution module 12 electrically connected with the control module 11. The control module 11 is further electrically connected with the wireless charging devices 10 and the devices 2 to be charged located in the active area through wireless signals, and the control module 11 collects working parameters of the wireless charging devices 10 and the devices 2 to be charged and controls working states of the devices 2 to be charged.
The power distribution module 12 is configured to adjust and distribute the load power of the charging connection with each wireless charging apparatus 10, so that the sum of the charging powers of all the devices to be charged 2 in the charging connection with each wireless charging apparatus 10 is not greater than the maximum charging power supported by the wireless charging apparatus 10. For example, the maximum output charging power supported by a single wireless charging device 10 is 1000W, and the sum of the powers of all the devices to be charged 2 that establish charging connection with the wireless charging device 10 is not more than 1000W through the power distribution module 12.
The power supply system is configured to arrange a plurality of high-power remote wireless charging devices 10 in a mesh shape in an active area of the device to be charged 2, detect and control working parameters and working states of each device to be charged 2 and each wireless charging device 10 in the active area in real time, and adjust and distribute load power for charging connection with each wireless charging device 10, so that the sum of charging powers of all devices to be charged 2 in charging connection with each wireless charging device 10 is not greater than the maximum charging power supported by the wireless charging device 10. Therefore, as long as the device to be charged 2 is in the active area covered by the wireless charging signal, when charging is required, the device to be charged 2 to be charged can be controlled to establish charging connection with the corresponding wireless charging device 10 by monitoring the wireless charging device 10 and the device to be charged 2, so that unattended power monitoring and remote wireless charging of all the devices to be charged 2 in the working area are realized, trivial work of frequently replacing batteries and individually monitoring the charging state of each device to be charged 2 is omitted, and during charging, the device to be charged 2 does not need to be moved out of the active area, so that the working efficiency is effectively improved. In addition, all the devices to be charged 2 in the active area are monitored through the centralized control platform, so that safety problems caused by over-charging and over-discharging can be avoided. Moreover, the wireless charging device 10 charges the device to be charged 2 in real time, so that the requirement of the device to be charged 2 on the battery capacity can be greatly reduced, and the space utilization rate of the device to be charged 2 is improved.
Further, the power distribution module 12 distributes the load power of the wireless charging device 10 based on a banker algorithm. In this embodiment, the specific principle of the banker algorithm belongs to the common knowledge in the art, and is not described herein again.
Specifically, the power distribution module 12 is provided with a first priority policy, a second priority policy, and a third priority policy for distributing the load power of the wireless charging device 10.
The first priority policy preferentially establishes a charging connection between the device to be charged 2 with the remaining capacity in the active area lower than a first set threshold and the corresponding wireless charging device 10, and when the capacity of the device to be charged 2 is restored to a second set threshold, the device to be charged 2 exits from the first priority policy. In this embodiment, the first priority policy allocates the output charging power in the wireless charging device 10 by using a remaining power priority principle, so that the device to be charged 2 currently at the insufficient power warning value is preferentially supplemented with electric energy. In this embodiment, the first set threshold is 20% of the total power, and the second set threshold is 50% of the total power, so that when the remaining power of the device to be charged 2 is lower than 20% of the total power, the charging connection with the wireless charging apparatus 10 can be preferentially established, and the priority processing object of the first priority policy cannot be exited until 50% of the total power is charged.
The second priority policy preferentially selects the combination of the devices to be charged 2 with the highest load power to establish charging connection with the corresponding wireless charging apparatus 10. According to the second priority policy, the output charging power in the wireless charging device 10 is distributed according to the principle of efficiency priority, so as to maximize the operating efficiency of the wireless charging device 10. For example, if there are three devices to be charged in the signal range of a certain wireless charging apparatus 10, the maximum output charging power of the wireless charging apparatus 10 is 1000W, and the charging powers of the three devices to be charged 2 are 800W, 500W, and 350W, respectively, then according to the second priority policy, two devices to be charged 2 with charging powers of 500W and 350W (the sum is 850W, less than 1000W, and greater than 800W) are preferentially connected to the wireless charging apparatus 10 for charging.
When the remaining power of all the devices to be charged 2 in the signal range of a certain wireless charging apparatus 10 is greater than the second set threshold and smaller than the third set threshold, the device to be charged 2 with the lowest remaining power is preferentially connected to the wireless charging apparatus 10 for charging according to the third priority policy. In this embodiment, the third set threshold is 90% of the total power, and assuming that the remaining power of three to-be-charged devices 2 within the signal range of a certain wireless charging apparatus 10 is 60%, 70%, and 80%, respectively, according to the third priority policy, the to-be-charged device 2 with the remaining power of 60% is preferentially connected to the wireless charging apparatus 10 for charging, and if the output charging power of the wireless charging apparatus 10 is still enough, the to-be-charged device 2 with the remaining power of 70% is then connected to the wireless charging apparatus 10 for charging, and then the to-be-charged device 2 with the remaining power of 80% is connected to the wireless charging apparatus 10 for charging.
With reference to fig. 1 to 3, the process of the control platform controlling any wireless charging device 10 to charge the device to be charged 2 within the signal range thereof is as follows:
s1: monitoring the residual capacity of the equipment to be charged 2;
s2: judging whether the device to be charged 2 with the residual capacity lower than 20% exists, if so, entering S3, and if not, entering S4;
s3: judging whether the sum of the charging power of all the devices to be charged 2 meeting the conditions in the signal range of the wireless charging device 10 is lower than the maximum output charging power (1000W) supported by the wireless charging device 10, if so, entering S300, and if not, entering S310;
s300: controlling all the devices to be charged 2 in the signal range of the wireless charging device 10 to establish charging connection with the wireless charging device 10, so as to charge;
s301: judging whether the electric quantity of the equipment to be charged 2 reaches more than 50%, if not, entering S300, and if so, entering S1;
s310: charging the corresponding equipment to be charged 2 by adopting an efficiency priority principle according to a second priority strategy, entering S301, and giving an alarm prompt to the equipment to be charged 2 which cannot establish charging connection with the wireless charging device 10;
s4: judging whether the equipment to be charged 2 with the residual capacity lower than 50% and higher than 20% exists, if so, entering S400, and if not, entering S410;
s400: charging the corresponding device to be charged 2 according to a second priority policy by using an efficiency priority principle, and entering S1;
s410: according to a third priority strategy, preferentially establishing charging connection between the equipment to be charged 2 with the lowest residual capacity and the wireless charging device 10;
s411: it is determined whether the amount of electricity of the device to be charged 2 is higher than 90%, and if yes, the charging is stopped, and if not, the process proceeds to S1.
Further, the power module 13 includes a plurality of rechargeable battery assemblies 130 and a power interface 131 electrically connected to each rechargeable battery assembly 130, wherein the power interface 131 is used for connecting to the commercial power. In this embodiment, through the arrangement of the rechargeable battery assembly 130, the capability of charging the device to be charged 2 can be continuously maintained under the condition of the power failure of the mains supply.
Furthermore, the rechargeable battery assemblies 130 are electrically connected to the power interface 131 through the POE switch 132. In this embodiment, through the setting of POE switch 132, can be according to the size change in active area, the coverage of wireless charging signal of real-time control.
