Description

Technical Field

[0001] The present invention relates to the technical field of electric power dispatching, and in particular to an electric power dispatching system based on big data. Background Art

[0002] The coin-operated rocking car is a children's toy car that can rock up and down with a shell made of fiberglass and rubber and driven by a motor. It only needs electricity to work and does not require special personnel to be on duty. It is an entertainment facility with a small investment and a high return.

[0003] At present, most coin-operated rocking cars on the market adopt a fixed time method, that is, after the coins are inserted, the coin-operated rocking car will work for a fixed time corresponding to the number of coins. When there are a large number of people queuing, such a billing method will cause crowding. At the same time, when the mall has a large flow of people, noisy noise will be generated. Properly increasing the volume of the speaker of the coin-operated rocking car can better improve the children's play experience. When the mall has a small flow of people, the speaker sound of the coin-operated rocking car can be appropriately reduced, and the power consumption range can be determined according to the machine power and the size of the children riding. Therefore, it is very necessary to design a power dispatching system based on big data with accurate estimation and macro dispatching. Summary of the invention

[0006] According to the above technical solution, the statistical module includes an infrared sensing module, a counting module, and a data uploading module. The infrared sensing module is electrically connected to the counting module, and the counting module is wirelessly connected to the data uploading module. The infrared sensing module is used to emit infrared rays to sense human body current, the counting module is used to count according to the electrical signal emitted by the infrared sensing module, and the data uploading module is used to upload the obtained traffic information to the merchant through the network in real time.

[0007] According to the above technical solution, the detection module includes a thermal imaging module, a measuring module, a load estimation module, and an ultrasonic module. The thermal imaging module is electrically connected to the measuring module, and the measuring module is electrically connected to the load estimation module. The thermal imaging module is used to detect infrared energy on the child and convert it into an electrical signal for thermal imaging. The measuring module is used to measure the child's body information. The load estimation module is used to estimate the load of the coin-operated rocking car based on the child's body information obtained by the measurement. The ultrasonic module is used to calculate the number of people in the queue using ultrasonic waves. The ultrasonic module includes a transmitting module, a receiving module, and a timing module. The transmitting module, the receiving module, and the timing module are electrically connected. The transmitting module is used to transmit ultrasonic waves to the queuing customers, the receiving module is used to receive the returned ultrasonic waves, and the timing module is used to record the time of the ultrasonic wave transmission and reception process.

[0008] According to the above technical solution, the power dispatching module includes a power interval allocation module, a volume adjustment module, a time adjustment module, and a display module. The power interval allocation module is electrically connected to the volume adjustment module, the volume adjustment module is electrically connected to the time adjustment module, and the time adjustment module is electrically connected to the display module. The power interval allocation module is used to allocate the single power consumption interval of the coin-operated rocking car according to the size of the shopping mall traffic flow, the volume adjustment module is used to adjust the speaker volume of the coin-operated rocking car according to the passenger flow, the time adjustment module is used to dynamically adjust the playable time according to the machine power and the estimated load, and the display module is used to display the playable time on the screen for children to choose.

[0009] According to the above technical solution, the power dispatching system based on big data has the following working steps:

[0010] Step S1: The statistical module is placed at the entrance and exit of the shopping mall to count the customers entering and leaving the shopping mall in real time. After the infrared sensing module senses the human body current, it sends an electrical signal to the counting module. The counting module counts each time it receives an electrical signal, and uploads the passenger flow B to the merchant in real time through the data uploading module;

[0011] Step S2: The power interval allocation module determines the single power consumption range of the coin-operated rocking car [d min , d max ] and sent to the merchant side;

[0012] Step S3: The detection module is placed on the coin-operated rocking car, and the body shape of the child on the car is detected by the thermal imaging module, and the body shape index Y is calculated by the measurement module;

[0013] Step S4: the load estimation module estimates the single load Q of the coin-operated rocking car according to the child's body index;

[0014] Step S5: A fixed queuing area is provided in the shopping mall. The ultrasonic module placed behind the queuing area emits ultrasonic waves. After hitting the person at the end of the queue, it returns and counts the time. The number of people N in the queue is determined based on the time T.

[0015] Step S6: The volume adjustment module dynamically adjusts the speaker volume Z according to the passenger flow B. The more passengers flow, the noisier the environment is, and the speaker volume needs to be increased. The fewer passengers flow, the less environmental noise there is.

[0016] The loudspeaker volume is turned down, and the relationship between the loudspeaker volume Z and the passenger flow is:

[0017] Z=ηB

[0018] Where η is the control coefficient;

[0019] Step S7: The time adjustment module adjusts the playable time according to the power of the coin-operated rocking car and the body index of the child, and displays the playable time on the display screen through the display module.

[0020] According to the above technical solution, in step S3, the method for calculating the child's body index is:

[0021] After receiving the thermal image of the child, the receiving module divides the image into two parts: head and body, and identifies the head radius R, body length l and shoulder width W. The calculation formula of the child's body index Y is:

[0022] Y=πR 2 +(l-2R)*W

[0023] Among them, the load of the coin-operated rocking car can be estimated according to the body index.

[0024] According to the above technical solution, in step S4, the calculation method of the single load of the coin-operated rocking car is:

[0025] The larger the child's body index is, the heavier the child is, and the corresponding single load of the coin-operated rocking car is larger. The child's body index has an upper limit and tends to be stable, which is logarithmically related to the single load of the coin-operated rocking car. The calculation formula of the single load Q of the coin-operated rocking car is:

[0026] Q=λlnY

[0027] Among them, λ is the control coefficient of load and child body index.

[0028] According to the above technical solution, step S5 further includes the following steps:

[0029] Step S51: For the convenience of regulation, the merchant will guide customers to queue in the designated area;

[0030] Step S52: When someone starts to queue, the transmitting module transmits ultrasonic waves to the queue;

[0031] Step S53: After the emitted ultrasonic wave contacts the queuing customers, it will return and be received by the receiving module;

[0032] Step S54: the timing module records the time T of this process;

[0033] Step S55: The number of people in the queue N is inversely proportional to the time T, and the calculation formula is: Among them, k is the control coefficient of time and number of people.

[0034] According to the above technical solution, in step S7, the method for calculating the power consumption of the coin-operated rocking car is:

[0035] The power range and passenger flow determine the power consumption of the coin-operated rocking car. The calculation formula for the power consumption U of the coin-operated rocking car is:

[0036]

[0037] Among them, U is the power consumption of the coin-operated rocking car, N is the number of people in the queue, and L is the coefficient value. When the value interval of N is [0, L), the power consumption satisfies the above formula. When N ≥ L, the power consumption satisfies the following formula. When N = 0, it means that the number of people in the queue is 0, and the power consumption at this time is d max , when N ≥ L, the power consumption at this time is d min .

[0038] According to the above technical solution, in step S7, the calculation formula of the playable time H is:

[0039]

[0040] Among them, P is the power of the coin-operated rocking car, λ is the control parameter, and the play time H is negatively correlated with the power size P, the power consumption U, and the body index Y.

[0041] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0042] (1) By setting up a counting module, the number of customers entering and leaving the mall is counted in real time, which effectively improves the accuracy of the power consumption estimation of the coin-operated rocking car;

[0055] A power dispatching system based on big data has the following working steps:

[0056] Step S1: The statistical module is placed at the entrance and exit of the shopping mall to count the customers entering and leaving the shopping mall in real time. After the infrared sensing module senses the human body current, it sends an electrical signal to the counting module. The counting module counts each time it receives an electrical signal, and uploads the passenger flow B to the merchant in real time through the data uploading module;

[0057] Step S2: The power interval allocation module determines the single power consumption range of the coin-operated rocking car [d min , d max ] and sent to the merchant side;

[0058] Step S3: The detection module is placed on the coin-operated rocking car, and the body shape of the child on the car is detected by the thermal imaging module, and the body shape index Y is calculated by the measurement module;

[0059] Step S4: the load estimation module estimates the single load Q of the coin-operated rocking car according to the child's body index;

[0060] Step S5: A fixed queuing area is provided in the shopping mall. The ultrasonic module placed behind the queuing area emits ultrasonic waves. After hitting the person at the end of the queue, it returns and counts the time. The number of people N in the queue is determined based on the time T.

[0061] Step S6: The volume adjustment module dynamically adjusts the speaker volume Z according to the passenger flow B. The more passengers flow, the noisier the environment is, and the speaker volume needs to be increased to attract more customers to consume. The fewer passengers flow, the less environmental noise there is, and the speaker volume needs to be reduced to reduce unnecessary power loss and provide a good experience for playing children. The relationship between the speaker volume Z and the passenger flow is:

[0062] Z=ηB

[0063] Where η is the control coefficient;

[0064] Step S7: The time adjustment module adjusts the playable time according to the power of the coin-operated rocking car and the body index of the child, and displays the playable time on the display screen through the display module.

[0065] In step S3, the method for calculating the child's body index is:

[0066] After receiving the thermal image of the child, the receiving module divides the image into two parts: head and body, and identifies the head radius R, body length l and shoulder width W. The calculation formula of the child's body index Y is:

[0067] Y=πR 2 +(l-2R)*W

[0068] Among them, the load of the coin-operated rocking car can be estimated according to the body index.

[0069] In step S4, the calculation method of the single load of the coin-operated rocking car is:

[0070] The larger the child's body index is, the heavier the child is, and the corresponding single load of the coin-operated rocking car is larger. The child's body index has an upper limit and tends to be stable, which is logarithmically related to the single load of the coin-operated rocking car. The calculation formula of the single load Q of the coin-operated rocking car is:

[0071] Q=λlnY

[0072] Among them, λ is the control coefficient of load and child body index.

[0073] Step S5 further comprises the following steps:

[0075] Step S52: When someone starts to queue, the transmitting module transmits ultrasonic waves to the queue;

[0076] Step S53: After the emitted ultrasonic wave contacts the queuing customers, it will return and be received by the receiving module;

[0077] Step S54: the timing module records the time T of this process;

[0078] Step S55: The number of people in the queue N is inversely proportional to the time T, and the calculation formula is: Among them, κ is the control coefficient of time and number of people.

[0079] In step S7, the calculation method of the power consumption of the coin-operated rocking car is:

[0080] The power range and passenger flow determine the power consumption of the coin-operated rocking car. The calculation formula for the power consumption U of the coin-operated rocking car is:

[0081]

[0082] Among them, U is the power consumption of the coin-operated rocking car, N is the number of people in the queue, and L is the coefficient value. When the value interval of N is [0, L), the power consumption satisfies the above formula. When N ≥ L, the power consumption satisfies the following formula. When N = 0, it means that the number of people in the queue is 0, and the power consumption at this time is d max , when N ≥ L, the power consumption at this time is d min , more accurately calculate the power consumption of a single game.

[0083] In step S7, the calculation formula of the playable time H is:

[0084]

[0085] Among them, P is the power of the coin-operated rocking car, λ is the control parameter, and the play time H is negatively correlated with the power size P, the power consumption U, and the body index Y.

[0086] Example 1: At a certain time, the real-time passenger flow at the entrance and exit of the shopping mall is measured to be B=100, the number of queues is N=10, the power consumption range of the coin-operated rocking car is [0.15, 0.2], and the head radius of a child is measured to be R=5cm, the height is l=40cm, and the shoulder width is W=15cm.

[0087]

[0088] It can be obtained that U = 0.2, according to the formula It can be obtained that H = 5 minutes.

[0090]

[0091] It can be obtained that U = 0.18, according to the formula So, H = 4 minutes

[0092] Example 3: At a certain time, the real-time passenger flow at the entrance and exit of the shopping mall is measured to be B = 200, the number of queues is N = 12, the power consumption range of the coin-operated rocking car is [0.15, 0.2], and the head radius of a child is measured to be R = 5cm, the height is l = 40cm, and the shoulder width is W = 15cm. According to the formula Y = πR 2 +(l-2R)*W, Y = 0.05㎡, assuming λ = -5, according to the formula Q = λlnY, Q = 15, assuming L = 100, according to the formula:

[0093]

[0094] It can be obtained that U = 0.19, according to the formula So, H = 6 minutes
