Accordingly, the sub server 130 may predict the amount of electric energy generation in the future by multiplying the number of times the cell-type piezoelectric power module 110 is pressed by a predetermined electric energy. The amount of electric energy generation in the future may be electric energy predicted to be generated by the energy harvesting power generation system 100 at a specific time period.

For example, the sub server 130 may predict the amount of electric energy generation in the future based on the number of times the cell-type piezoelectric power generation module 110 is pressed between 14:00 and 16:00 corresponding to the bar 1010. . The amount of electric energy generation in the future between 14:00 and 16:00 may correspond to the bar 1020 of the graph 1060 of FIG. 10.

The sub-server 130 may normally acquire electric energy usage. In general, the amount of electric energy used may correspond to the bar 1040 of the graph 1060 of FIG. 10. Typically, the amount of electric energy used may be a value previously stored. In general, the amount of electric energy used may be the amount of electric energy that is likely to be used in a specific space at a specific time. Here, the specific space may be a place where the energy harvesting power generation system 100 is located or a place near it. In addition, the specific time may be a time period in which a future electric energy generation amount is predicted to be generated. In general, the amount of electric energy used may be electric energy supplied by the energy storage unit 120 at a specific time period. According to FIG. 10, since the future electric energy generation amount 1020 corresponds to 14:00 to 16:00, the sub server 130 may obtain a normal electric energy usage corresponding to between 14:00 and 16:00.

The sub-server 130 may obtain normal electric energy usage from the main server 150. The sub server 130 may receive an input of a normal amount of electric energy from a user.

Referring to FIG. 9, the sub server 130 adds a future electric energy generation amount to the current electric energy amount stored in the energy storage unit 120, and obtains a subtracted energy amount obtained by subtracting the normal electric energy consumption ( 940).

Referring to FIG. 10, the current amount of electric energy stored in the energy storage unit 120 may correspond to a bar 1030. In addition, the amount of electric energy generation in the future may correspond to the rod 1020. In addition, the usual amount of electric energy may correspond to the rod 1040. In addition, the amount of subtracted energy may correspond to the bar 1050.

For example, the amount of electric energy generation in the future may be about 14:00 to 16:00. The current amount of electric energy stored in the energy storage unit 120 may be the amount of electric energy at the present time. In addition, the current amount of electric energy stored in the energy storage unit 120 may be from 0 o'clock to 14 o'clock.

When the amount of subtracted energy is less than the first threshold energy amount, the sub server 130 may perform a control step of charging the energy storage unit 120 from a general electric line. The general electric line may be a line receiving electric energy from the outside. The first threshold energy amount may correspond to the minimum amount of electric energy that must be stored in the energy storage unit 120. The first threshold energy amount may be a predetermined value. Also, the first threshold energy amount may be a value set by a user. The sub server 130 may charge the energy storage unit 120 from a general electric line so that the amount of deducted energy is maintained equal to or greater than the first threshold energy amount. That is, the sub-server 130 maintains the amount of energy subtracted from 0 to 14:00 in contrast to the small amount of power generation of the cell-type piezoelectric power module 110 from 14:00 to 16:00. Can be controlled.

The energy harvesting power generation system 100 according to the present disclosure maintains a certain amount or more of energy in the energy storage unit 120, so that even if the supply of electrical energy from the outside is suddenly cut off, the energy storage unit 120 can normally supply electric energy. I can.

The main server 150 may obtain a predicted electric energy generation amount for each period based on the number of vehicles entering and exiting the parking space for each period. For example, the predicted electric energy generation amount may be as follows.

Estimated electric energy generation = N * K * R

Here, N is the number of vehicles entering and exiting the parking space by period, K is the number of cell-type piezoelectric power generation modules 110 that vehicles step on to enter the parking space, and R is the cell-type piezoelectric power generation. It may be an amount of electric energy produced whenever the module 110 is stepped on. In this way, by checking the predicted electric energy generation amount of the main server 150, the user can make a plan to efficiently utilize the electric energy.

11 is a flowchart illustrating a method of operating an energy harvesting power generation system according to an embodiment of the present disclosure.

As already described, the cell-type piezoelectric power generation module 110 may perform step 1110 of generating electric energy by being pressurized by the driver's vehicle. In addition, a step 1120 in which the energy storage unit 120 is charged by electric energy generated by the cell-type piezoelectric power generation module 110 may be performed.

When the amount of electric energy charged in the energy storage unit 120 is lower than the second threshold energy amount, the energy storage unit 120 may perform an operation 1130 of transmitting a failure signal to the sub server 130. The second threshold energy amount may be a predetermined value. The second critical energy amount may be different from the first critical energy amount. The second critical energy amount may be a value for determining whether the cell-type piezoelectric power module 110 has a failure.

The failure signal may indicate a failure of the cell-type piezoelectric power generation module 110 pressurized by the user. When the cell-type piezoelectric power module 110 fails, it is possible to generate low electrical energy even if it is pressurized by a vehicle. The fault signal may include at least one of identification information of the cell-type piezoelectric power generation module 110, information on the type of fault, and information on a time when the fault signal is generated.

According to various embodiments of the present disclosure, the energy storage unit 120 is the energy storage unit when the electric energy received from the cell-type piezoelectric power module 110 is continuously k or more times less than the second threshold energy amount. A fault signal up to 120 can be transmitted to the sub server 130. k times may be a predetermined value. k may be a value of 10 or more and 20 or less. As described above, since the fault signal is transmitted to the energy storage unit 120 to the sub server 130 only when it is continued for k or more times, the reliability of the fault signal may be increased.

The sub server 130 may perform the step of outputting a fault signal. The sub server 130 may output a fault signal through sound or video. The sub server 130 may transmit a fault signal to an external device. The manager of the energy harvesting power generation system may check the fault signal and repair the cell-type piezoelectric power generation module 110.

12 is a flowchart illustrating a method of operating an energy harvesting power generation system according to an embodiment of the present disclosure. 13 is a diagram illustrating a method of operating an energy harvesting power generation system according to an embodiment of the present disclosure.

As described with reference to FIG. 5, the main server 150 may receive power generation information from the sub server 130. The main server 150 may perform an operation 1210 of accumulating and storing the power generation information received from the sub server 130. The power generation information may include information on the amount of electric energy generated by one vehicle. In addition, the power generation information received from the sub server 130 presses the identification information of the cell-type piezoelectric power generation module 110, information on the amount of generated electric energy, or the cell-type piezoelectric power generation module 110 It may include at least one of identification information of one driver.

The main server 150 may perform an operation 1220 of calculating an average value 1320 of the accumulated and stored power generation information. The main server 150 may calculate an average value of the recently predetermined n pieces of power generation information. n can be a natural number. n may be a predetermined value. Alternatively, n may be received by the user. Referring to FIG. 13, an average value 1320 of the latest generation information from the nth to the first may be calculated. Here, the average value 1320 may mean an average of the amount of electric energy generated by pressing one cell-type piezoelectric power module 110 by the driver's vehicle. When the energy harvesting power generation system 100 includes a plurality of cell-type piezoelectric power generation modules, the main server 150 may calculate an average value 1320 for each cell-type piezoelectric power generation module 110. .

The main server 150 may perform an operation 1230 of receiving new generation information 1310 from the sub server 130. The new power generation information 1310 may be power generation information received from the sub server 130 after the n-th time. As already described, the new power generation information 1310 may include information on the amount of electric energy generated by the driver's vehicle pressing the cell-type piezoelectric power generation module 110.

The main server 150 may perform an operation 1230 of obtaining a subtraction value 1330 by subtracting the new generation information 1310 from the average value 1320. The average value 1320 and the new generation information 1310 may be values related to the piezoelectric power generation module 110 of the same cell-type.

In addition, when the subtraction value 1330 is positive and the subtraction value 1330 is greater than or equal to the threshold value, the main server 150 indicates that there is an abnormality in the cell-type piezoelectric power generation module 110 pressed by the driver's vehicle. The determining step 1240 may be performed. Here, the threshold value may be a predetermined value. The threshold value may be a value for determining whether there is an abnormality in the cell-type piezoelectric power generation module 110. When the subtraction value 1330 is positive and is greater than or equal to the threshold value, it may mean that the new generation information 1310 is too low. Accordingly, the main server 150 may determine that there is an abnormality in the cell-type piezoelectric power generation module 110. The main server 150 may output a signal indicating an abnormality as an image or sound. In addition, the main server 150 may output a signal indicating that there is an abnormality to an external device. According to the present disclosure, since the manager of the energy harvesting power generation system 100 can quickly know the abnormality of the cell-type piezoelectric power generation module 110, the energy harvesting power generation system 100 can be operated stably. There is this.

The main server 150 is a cell-type piezoelectric power generation module 110 pressurized by the driver's vehicle when the subtraction value 1330 is positive and the subtraction value 1330 is greater than or equal to the threshold value lasts m times or more. It can be determined that there is something wrong with it. Where m can be a natural number. m may be a predetermined number or a value set by an administrator of the energy harvesting power generation system 100. As such, since the main server 150 determines that there is an abnormality only when it lasts m times or more, the reliability of the signal indicating the abnormality of the cell-type piezoelectric power generation module 110 generated by the main server 150 It can be high.

14 is a flowchart illustrating an operation of an energy harvesting power generation system according to an embodiment of the present disclosure. 15 is a view for explaining the operation of the energy harvesting power generation system according to an embodiment of the present disclosure.

The sub server 130 may perform the step 1410 of obtaining a speed at which the driver's vehicle enters the cell-type piezoelectric power generation module. The energy harvesting power generation system 100 may include a speed sensor for measuring the speed of a driver's vehicle. The sub server 130 may acquire the speed of the driver's vehicle based on the speed sensor. In addition, it is possible to measure the speed of the vehicle based on the distance between the plurality of cell-type piezoelectric power modules 110 determined in advance without the speed sensor and the time when the plurality of cell-type piezoelectric power generation modules 110 are stepped on. have. This has been described with reference to FIG. 5, and thus redundant descriptions are omitted.

The sub server 130 may perform an operation 1420 of acquiring information on the type of the driver's vehicle based on the power generation information and the speed. Vehicles of the same type have the same weight, and the distance between the front and rear wheels may be constant. Since the power generation information by the cell-type piezoelectric power generation module 110 varies depending on the weight of the vehicle and the entry speed of the vehicle, the energy harvesting power generation system 100 is based on the power generation information by the vehicle and the entry speed of the vehicle. Information on the type of vehicle can be obtained. In particular, in a domestic situation where there is little tuning for a vehicle, the same type of vehicle can generate the same power generation information.

The sub server 130 may store power generation information and information on the type of vehicle according to the speed as a table. The sub server 130 may acquire power generation information and information on a vehicle according to a speed based on the table. Here, the power generation information may mean electric energy generated by the cell-type piezoelectric power generation module 110 by the vehicle.

The power generation information may include information on a power generation pattern as shown in FIG. 15. The sub server 130 may obtain information on the type of the driver's vehicle based on the power generation pattern and the vehicle speed.

It can indicate when to pressurize. The area under the graph 1520 may represent the amount of electric energy generated by the cell-type piezoelectric power generation module 110 by the A vehicle of Y speed.

Since the Y speed is greater than the X speed, the time T1 generated by the vehicle A at the X speed may be longer than the time T2 generated by the vehicle A at the Y speed. In addition, the first peak 1511, which is power (watts) generated by the front wheel of vehicle A at X speed, may be smaller than the third peak 1521, which is power (watts) generated by the front wheel of vehicle A at Y speed. In addition, the second peak 1512, which is the power (watts) generated by the rear wheel of the vehicle A at the X speed may be smaller than the fourth peak 1522, which is the power (watts) generated by the rear wheel of the A vehicle at the Y speed.

A graph 1530 of FIG. 15 shows a power generation pattern when vehicle B presses the cell-type piezoelectric power generation modules 110 at an X speed. A graph 1540 of FIG. 15 shows a power generation pattern when vehicle B presses the cell-type piezoelectric power generation modules 110 at Y speed.

That is, the degree of similarity can be as follows.

Similarity = 1 / (((A1-C1)^2 + (A2-C2)^2 + ... + (An-Cn)^2)^(1/2))

A1, A2, ... An can represent the power according to the measured time. Specifically, A1 may be the power measured at the first time. An may be the power measured at the nth time. Similarly, C1, C2, ..., Cn may be power according to time included in one of the selected plurality of power generation patterns.

As already described, the energy harvesting power generation system 100 may include groups 410 and 420 including a plurality of cell-type piezoelectric power generation modules 110. The type of vehicle that measures a plurality of power generation patterns for a vehicle using a plurality of cell-type piezoelectric power generation modules 110 included in the groups 410 and 420 may be more accurately estimated. The sub-server 130 may obtain an average of the measured power by time of the plurality of power generation patterns as a representative power generation pattern. Alternatively, the sub server 130 may obtain a representative power generation pattern by averaging the power obtained by removing the maximum and minimum values for each time from the plurality of measured power generation patterns. In addition, it is possible to obtain the type of vehicle by comparing the representative power generation pattern with the stored power generation patterns.

The size of the vehicle may include one of a truck, a large, a medium, and a small vehicle. The vehicle model may mean a specific vehicle of a specific manufacturer. The sub server 130 may designate a parking location or set a parking cost differently according to the type of vehicle. In addition, the sub server 130 may generate various statistical data based on the acquired vehicle type. For example, when the entry rate of a large vehicle into a parking lot is high, a user may install a cell-type piezoelectric power generation module 110 capable of efficiently generating energy by a large vehicle at a specific location. In addition, the sub server 130 may designate a large vehicle to park at a specific parking position.
