Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.
Referring to fig. 3 and 4, fig. 3 is an interactive flowchart of a system for charging a battery charging cabinet according to an embodiment of the present invention, and fig. 4 is a flowchart of a method for charging a battery charging cabinet according to an embodiment of the present invention, as shown in fig. 3 and 4, the method for charging a battery charging cabinet includes the following steps S301 to S304.
In step S301, the charging and replacing server obtains the remaining power of the street lamp power supply from the street lamp control system or obtains the remaining power of the street lamp power supply according to the remaining power rule of the street lamp power supply configured in the charging and replacing server.
In this step, the charging and replacing server obtains the street lamp power supply residual power from the street lamp control system or obtains the street lamp power supply residual power according to the street lamp power supply residual power rule configured in the charging and replacing server. Specifically, regarding that the charging and replacing server obtains the residual power of the street lamp power supply from the street lamp control system, it should be noted that, firstly, the output power of each street lamp power supply, the number of street lamps accessed by the street lamp control system, and the rated power of each street lamp are recorded in the street lamp system. If the street lamp also has the dimming function, the rated power of the street lamp after dimming according to the dimming proportion is recorded in the street lamp control system. It can be understood that the rated powers of different dimming proportions are different, and the street lamp control system stores the parameters in the corresponding database system. When the street lamp control system controls the street lamp, the residual power of the power supply of the street lamp is calculated according to the control result, namely the residual power after power supply is carried out on the street lamp.
Optionally, the street lamp power supply residual power sent by the charging and replacing server is obtained by the street lamp control system through calculation according to the street lamp power supply output power, the power of each street lamp and the number of street lamps;
the calculation method comprises the following steps: the power output of the street lamp power supply is subtracted by the sum of the power of each street lamp.
Specifically, the example is given by three cases, when the street lamp control system plans to turn on street lamp lighting, the street lamp power supply residual power is calculated according to the number of street lamps required to be turned on and the power of each street lamp (for example, 100% brightness, the power is 400W rated, and 50% brightness, the power is 220W). And then the calculated residual power is sent to a charging and replacing server, and a replacing cabinet is informed to adjust a charging strategy in advance according to the residual power, so that influence on street lamp illumination after the street lamp is turned on is prevented. If the street lamp control system starts 50 street lamps at 6 points per day, the residual power is as follows: 30KW-400W 50 is equal to 30KW-20KW which is equal to 10 KW; when the street lamp control system plans to dim the street lamps to save energy and time of the street lamps, the residual power of the street lamp power supply is calculated according to the quantity of the street lamps with the brightness needing to be adjusted at this time and the power (for example, 50% of the brightness, the power is 220W) of each street lamp after dimming. After dimming is completed, the calculated residual power can be sent to the charging and replacing server to inform the power replacing cabinet to adjust the charging strategy according to the residual power, so that influence on street lamp illumination before dimming of the street lamp is prevented. If the street lamp control system adjusts the light after 2 am every day, the brightness of the street lamp is adjusted to 50%, and the dimming is performed for 50 street lamps, the residual power is as follows: 30KW-220W 50-30 KW-11 KW-19 KW. When the street lamp control system plans to turn off the street lamps, the residual power of the power supply of the street lamps is calculated according to the number of the street lamps needing to be turned off at this time and the power of each street lamp after the street lamps are turned off (if the power is 50W when the power needs to be supplied to the communication module and the detection module after the street lamps are turned off). After the street lamp is turned off, the calculated residual power can be sent to the charging and power exchanging server to inform the power exchanging cabinet to adjust the charging strategy according to the residual power, so that influence on street lamp illumination before the street lamp is turned off is prevented. If the street lamp control system is turned off after 7 am every day and 50 street lamps are turned off, the residual power is as follows: 30KW-50W 50 is 27.5KW, 30KW-2.5 KW.
In this embodiment, regarding obtaining the street lamp power supply residual power according to the street lamp power supply residual power rule configured in the power charging and swapping server, it can be understood that when the power charging and swapping server cannot obtain the street lamp power supply residual power from the street lamp control system, the street lamp power supply residual power rule may be configured in the power charging and swapping server. The configuration rule of the residual power of the street lamp power supply is as follows: and configuring the residual electric quantity according to the output power of the street lamp power supply, the number of the current street lamp power supplies connected to the street lamps and the street lamp control rule. The method specifically comprises the following steps: setting street lamp parameters: the street lamp power supply number, the power supply output power, the number of the accessed street lamps, the rated power of the street lamps and the power of the street lamps after dimming, namely the rated power of the street lamps after dimming according to a certain proportion. Still include street lamp control rule's setting: street lamp power serial number, time quantum, control mode, street lamp power surplus power, wherein, control mode divide into: the street lamp is turned on in full light, turned on in half light and turned off.
In step S302, the charging and replacing server sends the remaining power of the street lamp power supply to a power replacing cabinet.
It can be understood that, after receiving a request message for notifying the residual power of the street lamp power source sent by the street lamp control system, the charging and replacing server acquires the street lamp power source identifier and the residual power in the message; and returning a response message informing the street lamp control system of the residual power of the street lamp power supply, and identifying that the charging and replacing server has received the residual power information sent by the street lamp control system. Then, the power exchange cabinet accessed to the street lamp power supply is inquired according to the street lamp power supply identifier, and then the residual power is sent to the power exchange cabinet.
In step S303, the power exchange cabinet formulates a charging strategy according to the street lamp power supply residual power sent by the power charging and exchanging server.
Specifically, after receiving a request message for notifying the street lamp power supply residual power sent by the charging and replacing server, the replacing cabinet acquires the residual power. And the charging and battery-replacing management module detects the condition of the battery in the charging bin and acquires the charging power of the charging bin.
Optionally, the charging strategy is as follows:
if the total charging power required by the battery replacement cabinet is greater than the residual power sent by the battery charging and replacement server, entering a power output limiting mode to charge part of batteries needing to be charged;
and if the total charging power required by the battery replacement cabinet is less than or equal to the residual power sent by the battery charging and replacement server, entering a rated power output mode, and charging all batteries needing to be charged.
It can be understood that if the charging power required by all the charging bays is greater than the remaining power sent by the charging and swapping server, the charging bays enter the limited power output mode.
The power output limiting mode is specifically that the battery bin detection unit detects the residual capacity of the battery, the battery with the residual capacity larger than or equal to a set first threshold value is a first type battery, the battery with the residual capacity smaller than the set first threshold value is a second type battery, the charging bin preferentially charges the first type battery, and if the charging bin still has residual charging power, the charging bin charges the second type battery.
If the residual power obtained by the battery replacement cabinet is limited, the requirement that the batteries in all the charging bins are charged simultaneously cannot be met, the batteries are classified at the moment, the fully charged batteries are preferentially ensured to be ready to be charged, and the fact that the battery replacement cabinet can provide enough full-power batteries for users in time is ensured.
And if the charging power required by all the charging bins is less than the residual power sent by the charging and replacing server, the charging bins enter a rated power output mode to charge all the batteries required to be charged.
Optionally, the charging strategy is as follows:
after the power exchange cabinet acquires the residual power of the street lamp power supply, judging that the residual power of the street lamp power supply is smaller than the residual power of the street lamp power supply acquired last time, and adjusting to a charging strategy formulated by the residual power of the street lamp power supply sent by the power charging and exchanging server in advance for a certain time;
and after the power exchange cabinet acquires the residual power of the street lamp power supply, judging that the residual power of the street lamp power supply is larger than the residual power of the street lamp power supply acquired last time, and delaying for a certain time to adjust to a charging strategy formulated by the residual power of the street lamp power supply sent by the power charging and exchanging server.
Specifically, for example, after the battery replacement cabinet obtains the residual power rule parameter, if the rule parameter is to reduce the residual power (for example, the residual power of 07:00 to 18:00 is 6.875KW, and the residual power of 18:00 to 24:00 is 2.5KW), the charging mode corresponding to the smaller residual power needs to be adjusted in advance for a period of time (for example, the charging mode corresponding to 2.5KW needs to be adjusted at 17:30, so as to prevent the influence on the illumination of the street lamp); if the rule parameter is to increase the residual power (for example, the residual power of 02: 00-07: 00 is 4.75KW, and the residual power of 07: 00-18: 00 is 6.875KW), the charging mode corresponding to more residual power needs to be adjusted after a period of delay (for example, the charging mode corresponding to 6.875KW can be adjusted at 07:30, so that the influence on the street lamp illumination is prevented).
In step S304, the battery replacement cabinet charges the battery according to the charging strategy.
In this step, the power exchange cabinet charges the batteries in the charging cabinet according to the charging strategy described above.
As can be seen from the above, in the charging method of the battery replacement cabinet in the embodiment of the present invention, the residual power of the power supply of the street lamp is obtained from the street lamp control system through the battery replacement and charging server, or the residual power of the power supply of the street lamp is obtained according to the residual power rule of the power supply of the street lamp configured in the battery replacement and charging server; the charging and battery replacing server sends the residual power of the street lamp power supply to a battery replacing cabinet; the power exchange cabinet formulates a charging strategy according to the residual power of the street lamp power supply sent by the power charging and exchanging server; and the battery replacement cabinet charges the battery according to the charging strategy. According to the embodiment of the invention, the residual power of the street lamp power supply is obtained in real time through the power changing cabinet, and then the battery is charged by using the residual power of the street lamp power supply, so that the problem of conflict between the power of the power changing cabinet and the illumination of the street lamp is effectively avoided.
Fig. 5 is a second flowchart of a charging method for a battery replacement cabinet according to an embodiment of the present invention. Compared with the first embodiment shown in fig. 4, in this embodiment, before the charging and replacing server sends the remaining power of the street lamp power supply to the replacing cabinet, the charging and replacing server allocates the corresponding remaining power of the street lamp power supply to the replacing cabinet according to the percentage of the rated power of each replacing cabinet connected to the street lamp power supply to the sum of the rated powers of all the replacing cabinets connected to the street lamp power supply, and after the replacing cabinet obtains the remaining power, and a charging policy is formulated according to the remaining power for charging, the method further includes: the battery replacing cabinet generates electric quantity metering data and sends the electric quantity metering data to the battery charging and replacing server; and the charging and replacing server receives the electric quantity metering data and stores the electric quantity metering data locally, and then forwards the electric quantity metering data to the street lamp control system. The method for charging the battery replacement cabinet comprises the following steps S401-S406.
In step S401, the charging and swapping server obtains the street lamp power supply residual power from the street lamp control system or obtains the street lamp power supply residual power according to the street lamp power supply residual power rule configured in the charging and swapping server.
In step S402, before the charging and replacing server sends the street lamp power supply residual power to the replacing cabinets, the charging and replacing server allocates a corresponding street lamp power supply residual power to the replacing cabinets according to a percentage of a rated power of each replacing cabinet connected to the street lamp power supply to a sum of rated powers of all the replacing cabinets connected to the street lamp power supply.
In this step, before the charging and replacing server sends the street lamp power supply residual power to the replacing cabinet, the charging and replacing server allocates the corresponding street lamp power supply residual power to the replacing cabinet according to the percentage of the rated power of each replacing cabinet accessed to the street lamp power supply to the sum of the rated powers of all the replacing cabinets accessed to the street lamp power supply, and it can be understood that after receiving a request message for notifying the street lamp power supply residual power sent by the street lamp control system, the charging and replacing server obtains the street lamp power supply identifier and the residual power in the message; and returning a response message informing the street lamp control system of the residual power of the street lamp power supply, and identifying that the charging and replacing server has received the residual power information sent by the street lamp control system. Then, the power exchange cabinets which are connected with the street lamp power supply are inquired according to the street lamp power supply identification (1 street lamp power supply can be connected with 1 or more power exchange cabinets), and then the residual power is sent to the power exchange cabinets. And if 1 street lamp power supply is connected into a plurality of power exchange cabinets, distributing the residual power sent by the street lamp control system according to the percentage mode that the rated power of each power exchange cabinet accounts for the sum of the rated powers of all the connected power exchange cabinets. For example, if a street lamp power supply is connected into 4 power change cabinets, the rated power of each power change cabinet is 5 KW; the remaining 10KW sent by the street light control system. The remaining power allocated to each battery changing cabinet is 2.5 KW.
10KW*(5KW/(5KW+5KW+5KW+5KW))＝2.5KW
In step S403, the charging and replacing server sends the remaining power of the street lamp power supply to the power replacing cabinet.
In step S404, the power exchange cabinet makes a charging strategy according to the street lamp power supply residual power sent by the power charging and exchanging server.
In step S405, the battery replacement cabinet charges the battery according to the charging strategy.
In step S406, the battery swapping cabinet generates electricity quantity metering data and sends the electricity quantity metering data to the battery charging and swapping server; and the charging and replacing server receives the electric quantity metering data and stores the electric quantity metering data locally, and then forwards the electric quantity metering data to the street lamp control system.
In this step, the battery swapping cabinet generates electric quantity metering data and sends the electric quantity metering data to the battery charging and swapping server; the charging and replacing server receives the electric quantity metering data and stores the electric quantity metering data locally, then forwards the electric quantity metering data to the street lamp control system, and specifically, the replacing cabinet supplies current and voltage to a power supply of the replacing cabinet through the electric quantity metering module, meters used electric quantity, and then transmits the electric quantity metering data and time data to the charging and replacing server through the communication module. The electricity metering is counted according to each hour, so that the power company can calculate the electricity fee according to the time period, and the electricity fee corresponding to the electricity utilization peak period is different from the electricity fee corresponding to the electricity utilization valley period. And the charging and battery-replacing server receives the electric quantity metering data and the time data returned by the battery-replacing cabinet, stores the electric quantity metering data and the time data to the local, and then sends the electric quantity metering data and the time data to the street lamp control system for electric charge settlement.
