Smart charging system and charging resource allocation processing method thereof

The invention relates to a charging system, in particular to a smart charging system and a charging resource allocation processing method thereof.

In recent years, technology has been changing with each passing day and environmental awareness has risen. Many teaching units have introduced digital devices into the teaching environment based on environmentally-friendly paperlessness and interest in learning. The digital devices include tablet computers (such as Ipad), Chrome Book, and notebooks. Computers, etc., when such digital devices are used in a teaching environment, they must be powered by the battery they are equipped with, so the teaching unit provides a charging device (such as a charging synchronous car) in the prior art. It can store several to dozens of digital devices (for example, 30 to 50) and charge them at the same time, but the charging current (load current) required for charging dozens of digital devices at the same time may cause the environmental power distribution system. Overloading affects other consumers and causes user confusion.

The charging device has a plurality of sockets therein, and the charging schedule is programmed to prevent the required charging current from being overloaded by the environment distribution system and affecting other power devices. The charging schedule includes: The drawing sub-area sets a fixed time and charges in turn; or manually sets the schedule of several designated areas and charges in a fixed time in turn. It is usually necessary to divide the charging area through the above design to avoid excessive charging current and prevent overload of the power distribution system. For example, if a charging device can accommodate 40 digital devices at the same time and draw into 4 charging areas, ie, each area Corresponding to 10 digital devices, the charging device can only charge the digital devices in a certain area at the same time, and then charge the digital devices in other areas in a fixed order after a fixed time interval to avoid power distribution. The system is overloaded. In addition, there is a wall-mounted charging device or a portable charging device that can be placed on a table. This type of charging device is usually used for storing a small number of digital devices, and the number of students in a classroom may be on the wall. More than one expansion on the wall, but when most of the charging devices are connected in series, they can usually only be connected to the mains power supply (AC power supply), so if one or more charging devices are simultaneously charged, the environmental distribution system is overloaded. Affecting other consumers, it is more likely to cause problems for users.

It can be seen from the above that the number of storages that can be supported by the charging synchronous car in the prior art must be fixed at the time of shipment, and cannot be freely expanded, connected and adjusted according to the needs of the use environment, and the storage of the wall-mounted and portable charging device can be realized. Although the number is small, when multiple charging devices are used at the same time, the environmental distribution system is overloaded and the other electrical devices are affected. Furthermore, the charging schedule design in the prior art must first assume that the power consumption of each region is equivalent. Average and normal, charging at a fixed time and taking turns will not cause overloading of the power distribution system. However, the way in which each area is charged in turn and the time of each charging cycle is the same is actually a very inefficient charging method, because the actual In the application, the power consumption status of each area is often different, and even the power consumption of different areas is very different. As for the manual setting of charging schedule and time, the user needs to separately consider the power consumption status of each area and set the required area. The charging time increases the inconvenience of the user, and is not an efficient charging method. The prior art does not completely prevent the system from being overloaded, and it is impossible to provide users with the ability to expand and combine in different use environments; therefore, how to better meet the needs of users and solve the problems of the prior art is indeed The need to propose a better solution.

In order to illustrate a specific application manner of the above preferred embodiment of the present invention, a series of smart charging devices are serially connected to illustrate a process of allocating processing to a charging resource, which has a first charging device L1 and a second charging device L2. The three charging devices L3 and the fourth charging device L4 have a total of four charging devices L1 to L4, and the first charging device L1 is directly connected to a mains power supply (AC 110V/220V) and is the main charging device 10 described above. The second to fourth charging devices L2 to L4 are respectively the aforementioned sub-charges The second charging device L2 is electrically connected to the first charging device L1 and the third charging device L3, and the third charging device L3 is electrically connected to the fourth charging device L4. The serial connection mode is sequentially expanded. When the main charging device 10 first reads the load signal of a built-in power supply plug 11 and a preset limit value, it is determined whether there is still an unread extended power supply plug 21 And performing a predictive calculation mode for the unread extended power strip 21, wherein the predictive calculation mode presets a read time, and the main charging device 10 sequentially reads all the expansions during the read time. The load signal of the power supply port 21 is used to determine whether all the load signals are abnormal. After the operation, all the load signals are stored and recorded. In this embodiment, the preset limit value may be a current limit value, and the load signal may be A current value.

In the above table, the current values of the power strips of the charging devices L1 to L4 are different, and the charging devices L1 to L4 are connected in series with each other through the first and second outlets to perform electric power. In the embodiment, the reading time can be 15 seconds, 30 seconds, 45 seconds, and 60 seconds; since the L1 is connected to the mains power source and becomes the main power source, the strip is turned on after detecting the power. The current value, after 15 seconds, turns off the Strip and turns on the Outlet to detect the current value. At this time, L1 supplies power to L2, so the current value detected by the L1 Outlet is the current value of the Strip of L2; after 30 seconds, L2 is turned off. Strip, open Outlet detection current value, L1 Outlet will detect a new current value, which is the current value of L3 Strip, and L2 Outlet can also detect the current value of L3 Stiip; After 45 seconds, L3 turns off its Strip and turns on its Outlet detection current value, while L1's Outlet will detect another one. The new current value is the current value of the strip of L4, and the Outlet of L2 also detects the current value of the strip of L4, and the Outlet of L3 also detects the current value of the strip of L4; after 60 seconds, L1 That is, the Outlet is turned off, so that all the serially connected charging devices L1~L4 are powered off, and L1 already knows and stores and records all the current values, ready to perform a scheduling process and allocate charging time.

In addition, in the following table, the current values of the power strips of the charging devices L1 to L4 are completely the same, and the prediction calculation mode is processed in the same manner as described above, but the predetermined reading time (for example, 15 seconds, Cutting is performed for 30 seconds, 45 seconds, or 60 seconds, etc., and the charging devices L1 to L4 are separated by the reading time, and all the expanded power strips 21 are sequentially read by the main charging device 10 during the reading time. The load signal, at the same time, judge whether all the load signals are abnormal. After the operation, all the load signals are stored and recorded, and then it is confirmed that there is no unread expansion power supply plug 21, and the calculation result according to the foregoing prediction and the pre-predetermined Set a limit value, execute a schedule setting process, and allocate charging time.

In order to further explain the schedule setting process and the method of allocating the charging time of the present invention, as shown in the following table, since the above L1 value record is obtained by successively connecting three charging devices L2 to L4 in series, a majority serial mode is executed. The schedule setting process detects that three charging devices L2~L4 are connected in series, and if the sum of the current values of all the power strips is less than the preset limit value (such as 8A), the strip+Outlet is simultaneously turned on (On ), and set to a schedule, if the sum of the current values is not less than 8A, then make a subsequent judgment: if the serialized L2 schedule has been preset to two schedules, and determine the strip current of Strip1 and L2 of L1 If the sum of the values is less than 8A, the schedule setting is the same as L2; if the serialized L2 schedule is pre-prepared Set to two schedules, and judge that the current value of the Strip+L2 Strip of L1 is not less than 8A, it is directly divided into two schedules.

Since the L2 value record is followed by serially connecting the two charging devices L3, L4, the scheduling process of the majority serial mode is executed, which detects the serial connection of the two charging devices L3, L4, if the current values of all the power strips If the sum is less than 8A, the strip+Outlet is set to On at the same time and set to a schedule. If the sum of the current values is not less than 8A, it is divided into two schedules; further, when the L3 value is recorded, a subsequent charging device L4 is obtained. Therefore, the scheduling process of a single serial mode is performed, and the detection is connected in series with a charging device L4. If the sum of the current values of all the power strips is less than 8A, the strip+Outlet is simultaneously on and set to a schedule. If the sum of the current values is not less than 8A, it is divided into two schedules; furthermore, when the L4 value is recorded to obtain a non-series charging device, a schedule setting process without a serial connection mode is executed, which detects only the own Strip, if the sum of the current values is less than 8A, the strip itself is directly On, and its Outlet is not allowed to operate, and is set to a schedule. When all the schedule setting processes and the allocated charging time are completed, the main charging device is completed. 10 The charging control signal and power are transmitted to the connected sub-charging device 20, and control and transmission are started to perform charging.

It must be noted that since the schedule and charging time set by L1 are the same as L2, the power-on time of the Strip and Outlet is allocated, but it must be calculated by the current value detected by L2;

As shown in the above table, the current values of the charging devices L1 to L4 are 3A, 2A, 6A, 2A, respectively, and one charging cycle time is Time=60min, and the sum of the current values detected by L2 is Cmax=(L2)+ (L3) + (L4) = 2A + 6A + 2A = 10A; Strip + Outlet _time = (2A × Time) / Cmax = 12min; Outlet _time = (8A × Time) / Cmax = 48min. Because L3 is set to a schedule, the Strip+Outlet is turned on for 60 minutes, and L4 is also set to a schedule. Therefore, the Strip+Outlet is also turned on for 60 minutes, and the L2 system is set to two schedules as described above. Therefore, the opening time of the Strip and Outlet is allocated, and the allocation is the same as the above, L2 has Cmax=10A, Strip _time =12min, and Outlet _time =48min.

The charging resource allocation processing method of the smart charging system can be further summarized by the description of the preferred embodiment of the present invention and the application manner thereof, and the main charging device 10 having the built-in power supply plug 11 is connected to the main power supply. And the other sub-charging device 20 having the expanded power strip 21, as shown in FIG. 3, and the main charging device 10 performs the following steps: reading the load signal of the built-in power strip 11 and a preset a limit value (S31); determining whether there is still an expanded power strip 21 of the unread sub-charging device 20 (S32); if so, performing the sub-charging device 20 for the unread extended power strip 21 a predictive calculation mode (S33), and returning to the step of "reading the load signal of the built-in power strip 11 and a preset limit value (S31)"; If not, performing a scheduling process and allocating the charging time according to the result of the prediction calculation, the preset limit value, and causing all the power outlets 11, 21 to be charged according to the result of the scheduling setting and the charging time (S34); Detecting the load signals of all the power outlets 11, 21 in sequence (S35); determining whether all the schedules are completed (S36); if yes, returning to the foregoing "the result of the prediction calculation, the preset limit value is executed.
