Description

Technical Field

[0001] The present invention relates to the field of intelligent security technology, and in particular to a method for implementing voice advertising of an access control card reader supporting operations. Background Art

[0002] At present, community access control systems are mainly divided into owner-built type and operator-built type. The owner-built type is usually the access control system built and handed over by the developer when it is delivered, and the later owner-built type. Regardless of which type of self-built type, its characteristic is that the system only covers the community, and is often a stand-alone system. The demand for operation is not strong, and it can open the community gate normally. The typical characteristics of the operator-built type are: 1. The owner does not need to pay; 2. The system can achieve the security level of community entry and exit from a technical level; 3. It has the ability to operate, so as to realize the later capital recovery of the initial capital investment, and even bring profits to the operating company. At present, the operation point of the operator-built type is mainly advertising, that is, relying on advertising to recover the initial investment and later maintenance costs. The forms of advertising mainly include: 1. Print advertising; 2. Streaming media advertising, which is usually video and voice multimedia advertising with display screens.

[0003] However, the development and operation of the existing community access control system, in which streaming media advertising usually uses video and voice multimedia advertising with display screens, has the following disadvantages: 1. Low IP level; 2. High power consumption; 3. High maintenance rate; 4. Too much investment in hardware equipment and too long capital recovery period. Summary of the invention

This program includes the communication program in the card reader and the background communication program;

[0067] Step S23: perform joint debugging of the communication module, and debug the sending of voice entry related parameters to the card reader through the background.

[0068] Specifically, the voice advertisement playing weight allocation algorithm in step S3 includes the following steps:

[0069] Step 31: Define voice advertisement entries as X1, X2…X n ; The appointment time is T1, T2…T n ; The time-sharing volume parameters are A1, A2…A n ; Advertising fee: M1, M2…M n ; The parameters for manual participation are Q1, Q2…Q n ;

[0070] For the manual participation parameters Q1, Q2…Qn, where 0<Qn≤10, the default value is 1, and no manual participation is made when the default value is used; when it is less than 1, the weight is lowered to reduce the playback probability; when it is greater than 1, the weight is increased to increase the playback probability, and the weight is increased by a maximum of 10 times.

[0071] Step 32: Algorithm design, count all the advertisement items that need to be played according to the reservation period, assuming that all the advertisement items to be played are X1, X2…X n Some entries x1, x2…x in m It needs to be played during a specific reservation period; the corresponding advertising fee for the relevant voice item that needs to be played is m1, m2…m m ;

[0072] In a specific reservation period, according to the principle of more input and more playback, the voice items x1, x2…x that need to be played in this period m The corresponding playback weights are arrays w1, w2…w m , the weight w is calculated by the following formula: where j = 1, 2…m, m i The amount of money invested in the target playback voice entry;

[0073] Assume that the artificial participation parameters Q1, Q2…Q n The relevant voice manual participation parameters for a specific appointment period are q1, q2…q m , then according to the formula w' i =w i ×q i To adjust the weights w1, w2…w of the voice items played during this period m , the adjusted weights are w'1, w'2…w' m , where i=1,2…m;

[0074] The adjusted playback weights are normalized, and the normalized result is w″1,w″2…w″ m , the standardized formula is Where j = 1, 2…m;

[0075] Generate a playlist during the scheduled playback period. Assume that the length of a cycle list played in a loop during the scheduled period is l, and assume that the playlist is x1, x2…x l , then the playlist random number generator and the standardized play weight in the table jointly determine, each time using the random function rand() according to x1, x2…x m Generate a corresponding playback random number array r1, r2...r in sequence m , using the formula r' i =w″ i × i Use the standardized weight to correct the size of the random number and get the corrected random array r'1, r'2...r' m , and then according to the maximum value max(r'1,r'2…r' m) to determine the specific play item of the m voice advertisement in the time period; and finally generate the play list in the play period as x1, x2…x l ;

[0076] Then, the final all-day playlist is assembled according to the time-sharing volume parameters of different scheduled play periods. Assuming that the all-day time-sharing volume parameters are A1, A2…A n The volume parameter of the reservation period is a i , then the playlist of the last cycle of the reservation period is a two-dimensional array:

[0077] {(a i ,x1),(a i ,x2)…(a i ,x l )}

[0078] Finally, according to the number of time periods n throughout the day, combined with the time-sharing volume parameters, the playlist generation algorithm for each time period is used to generate the playlist for the whole day. The list is as follows:

[0079]

[0080] n is the number of time periods throughout the day, and l is the length of the playlist in the current time period;

[0081] Step 33: According to the definition of voice advertisement items, reservation time period, time-sharing volume, advertisement fee, and manual participation parameters sent by the background to the access control card reader, write a program in the MCU to automatically produce a full-day playlist to achieve the adaptability of volume and environment, and achieve the goal of paying more and playing more in the time period according to the time period selected when the advertisement is released. In addition, the operator retains the opportunity for manual participation and adjustment. The operator can adjust the playback volume of specific advertisements through manual participation parameters. The environmental adaptability of the volume achieves different volumes at different times of the day and night, or even multiple time periods, such as: the volume of the morning, noon, afternoon, and midnight of the night is different, so that the purpose of playing voice advertisements is achieved without disturbing the public, and it can be better accepted by community owners or property, which is convenient for operation and promotion.
