[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the present application will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0026] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0027] Some embodiments of the present application will be described in detail below in combination with the drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] In the security system in the related art, the number of collection devices working at the same time is small most of the time, at this time, the throughput data A of the security host 安防 is required to be small, only in individual peak time, the number of collection devices working at the same time will increase, the throughput data A of the security host 安防 is required to be high. Therefore, how to reduce the demand of the throughput data A of the security host in the peak period is the key to reduce the hardware cost of the security host. 安防

[0029] Referring to Figure 1 ​At least one embodiment provides a dynamic multi-source security system, comprising: a security host and a plurality of collection devices in communication connection with the security host; each collection device is arranged on a corresponding intelligent door lock; the collection device is configured to form a transmission data packet after collecting valid data, and a transmission node formed according to a time axis sends corresponding throughput data of the transmission data packet to the security host, wherein the throughput data represents the data size received per unit time; the security host is configured to compare the security host throughput data A 安防 with the total throughput data A 总 of the currently activated collection devices, and sends corresponding transmission instructions to the currently activated collection devices; when A 总 ≤A 安防 , the currently activated collection devices are configured to send the transmission data packet to the security host; when A 总 >A 安防 , the contact devices among the currently activated collection devices are configured to send the complete transmission data packet to the security host, and the non-contact devices among the currently activated collection devices are configured to split the corresponding transmission data packet for sending to the security host, and the sum of the new throughput data formed by all the transmission data packets is less than A 安防 .

[0030] Specifically, the contact device can include but is not limited to a fingerprint device, a touch sensing device.

[0031] Specifically, the non-contact device can include but is not limited to a camera.

[0032] Specifically, since the data collected by the contact device has high accuracy, it needs to be sent completely to the security host.

[0033] Specifically, when the non-contact device works in the daytime, the accuracy of image data is high, but there is noise, so the accuracy of voice data is relatively weak; when the non-contact device works at night, the accuracy of image data is weak, but the noise is small, so the accuracy of voice data is high; the non-contact device splits the image data or voice data from the transmission data packet according to different environments, which can output accurate security results in the corresponding environment (daytime or night).

[0034] The security host comprises: a comparison unit configured to calculate the total throughput data A 总 of the activated collection devices according to all the throughput data received in the same transmission node, and compare the security host throughput data A 安防 ; wherein the activated collection device represents the collection device sending the throughput data in the current transmission node; a first execution unit configured to, if A 总 ≤A 安防The system issues a transmission command to the activated acquisition device; the acquisition device is configured to send a transmission data packet to the security host according to the transmission command; the second execution unit is configured to, if A 总 >A 安防 The security host is also configured to send transmission commands to each activated contact device and split commands to each non-contact device; among the currently activated acquisition devices, contact devices are configured to send complete transmission data packets to the security host, and non-contact devices are configured to split corresponding transmission data packets to send to the security host, and the sum of the new throughput data formed by all transmission data packets is less than A. 安防 Among them, the sending instruction and the splitting instruction are both transmission instructions; the parsing unit is configured to parse the received transmission data packets, obtain the security results, and send the security results to the corresponding acquisition device.

[0035] By transmitting the data packets collected by the acquisition devices along the timeline through transmission nodes, and by using the required throughput data A from all acquisition devices within the same transmission node... 总 With security host throughput data A 安防 The comparison results are used to adjust the transmitted data packets to meet the transmission requirements of the acquisition devices. Using batch sending reduces the number of data packets simultaneously received by the security host from the acquisition devices, thereby reducing the load on the security host's throughput. 安防 The demand. Meanwhile, in A 总 >A 安防 The transmitted data packets are split into smaller, more accurate segments, such that the sum of the new throughput data generated from these split segments equals A. 安防 This further reduces the data throughput of the security host. 安防 This addresses the need for hardware configuration reduction in security hosts, thereby lowering the overall cost of security systems.

[0036] Specifically, when the contactless device is in the first time period, the contactless device is configured to extract image data from the transmission data packet to form a new transmission data packet; when the contactless device is in the second time period, the contactless device is configured to extract voice data from the transmission data packet to form a new transmission data packet.

[0037] Specifically, the first time period can be from 6:00 to 18:00 Beijing time on the same day, and the second time period can be from 18:00 to 6:00 the next day Beijing time.

[0038] Specifically, when the contactless device extracts image or voice data from the corresponding transmission data packet, the sum of the new throughput data formed by all the transmission data packets is greater than A. 安防When the non-contact device splits the corresponding transmission data packet again according to the split ratio, until the sum of the new throughput data formed after the splitting again is equal to A 安防 ; K = (A 安防 -A 总接触 ) / A 总非接触 , wherein K represents the split ratio, A 总接触 represents the total throughput data of the contact device, and A 总非接触 represents the total throughput data of the non-contact device after the initial splitting.

[0039] Specifically, after the non-contact device splits the image data or voice data from the corresponding transmission data packet, the sum of the new throughput data formed by all the transmission data packets is still greater than A 安防 , in order to ensure that the security host can receive the current batch of data, the data collected by the non-contact device needs to be split to avoid packet loss, delay and other problems caused by high load of the security host.

[0040] According to the split ratio, the transmission data packet collected by the collection device is proportionally reduced, thereby reducing the demand for the throughput data A 安防 of the security host in the peak period.

[0041] It should be noted that the throughput data A 安防 is the throughput data value of the normal working time of the security host, which is less than the limit throughput data value A 安防极限 of the security host.

[0042] Specifically, the data of each collection device changes in real time, and even if A 安防 ≤ (A 总接触 +A 总非接触 ) ≤ A 安防极限 , the split ratio K is kept unchanged within a certain time to avoid data fluctuations.

[0043] The specific splitting process of the collection device is described below. The steps of splitting the transmission data packet by the non-contact device according to the splitting instruction include: receiving the splitting instruction; obtaining the split ratio K from the splitting instruction; splitting the transmission data packet according to the split ratio to form a new transmission data packet.

[0044] Please refer to Figure 2 . Specifically, step S2 includes:

[0045] S21: extracting the first section data of K / 3 transmission data packet size;

[0046] S22: extracting the tail section data of K / 3 transmission data packet size;

[0047] S23: extracting the middle section data of K / 3 transmission data packet size from the remaining data in the transmission data packet.

[0048] Specifically, by using the first section data, the tail section data and the middle data extraction mode, the data continuity can be ensured, and the data analysis accuracy can be improved, that is, the influence on the analysis result after data compression is reduced.

[0049] It should be noted that the data in the transmission data packet is all valid data, that is, the data is preprocessed by the acquisition device in advance.

[0050] Please refer to Figure 3 In some embodiments, the security host further comprises an elimination unit; the elimination unit is configured to screen out the associated acquisition device from all activated acquisition devices according to the preset association information, eliminate the throughput data of the remaining associated acquisition devices except the acquisition device with the maximum throughput data in each group of associated acquisition devices from all received throughput data, and store the eliminated throughput data of the acquisition device in the cache area.

[0051] Specifically, when security is performed, some access control with high security level is provided on a smart door lock with multiple acquisition devices, the multiple acquisition devices are associated and used for joint verification, so as to improve the security level. In order to reduce the performance requirement of the security host, the acquisition device with the maximum throughput data in the associated acquisition device is uploaded, and the throughput data collected by the remaining acquisition devices is temporarily stored in the cache area, and then uploaded and stored when the security host is idle, so as to facilitate subsequent tracing.

[0052] In some embodiments, the security host further comprises a verification unit configured to perform data verification on all transmission data packets, mark the acquisition device corresponding to the transmission data packet when data anomaly of the transmission data packet is detected, for subsequent maintenance; and the elimination unit is further configured to eliminate the acquisition device with the mark from the associated acquisition devices. Since the acquisition device may be damaged or tampered with during use, it is necessary to perform data verification on the transmission data packet, mark the acquisition device with data anomaly, and timely remind the staff to maintain. At the same time, for the associated acquisition device, the acquisition device with the mark will not be transmitted next time, so as to ensure the accuracy of subsequent security host analysis.

[0053] Specifically, the security host further comprises a third execution unit configured to, when no acquisition device is activated, that is, A 总 =0, sequentially send a sending instruction to the acquisition device corresponding to the throughput data stored in the cache area. In other embodiments, the acquisition device with the maximum throughput data in the associated acquisition device can be selected. 总≤ a, where a is a human set value, that is, when the security host is idle, the transmission data packet of the collection device corresponding to the throughput data stored in the cache memory is uploaded.

[0054] Please refer to Figure 2 At least one embodiment provides a security method of a dynamic multi-source security system as described above, by transmitting the transmission data packet collected by the collection device to the transmission node on the time axis, and comparing the result of the throughput data A 总 of the security host with the throughput data A 安防 of all collection devices in the same transmission node, to adjust the transmission data packet to meet the transmission requirements of the collection device. The batch sending mode is adopted to reduce the number of transmission data packets sent by the collection device received by the security host at the same time, thereby reducing the demand for the throughput data A 安防 of the security host. At the same time, when A 总 > A 安防 , the transmission data packet is split, so that the sum of the new throughput data formed by the split transmission data packet is equal to A 安防 , further reducing the demand for the throughput data A 安防 of the security host, so as to reduce the hardware configuration of the security host and the overall cost of the security system.

[0055] Specifically, the security method comprises the following steps:

[0056] S110: The collection device collects valid data, and packs the valid data to form a transmission data packet after the collection is completed.

[0057] S120: The transmission data packet corresponding to the throughput data is sent to the security host according to the transmission node on the time axis.

[0058] Wherein, the throughput data represents the size of the data received per unit time.

[0059] S130: The security host calculates the total throughput data A 总 of the activated collection device according to all the throughput data received in the same transmission node, and compares it with the throughput data A 安防 of the security host.

[0060] Wherein, the activated collection device represents the collection device that sends the throughput data in the current transmission node.

[0061] S140: If A 总 ≤ A 安防 , send a sending instruction to the activated collection device, and the collection device is configured to send the transmission data packet to the security host according to the sending instruction.

[0062] S150: If A 总 > A 安防 , the security host is further configured to issue a split instruction to the activated collection device; the collection device is further configured to send the split transmission data packet to the security host after splitting the transmission data packet according to the split instruction, and the sum of the new throughput data formed by all split transmission data packets is equal to A 安防 .

[0063] S160: The security host analyzes the received transmission data packet, obtains the security result, and sends the security result to the corresponding collection device.

[0064] After step S120 and before step S130, the security method of the dynamic multi-source security system further comprises:

[0065] S121: According to the preset association information, the associated collection devices in all activated collection devices are screened out.

[0066] Wherein, the preset association information is a human input value, indicating that two collection devices are collection devices on the same smart door lock.

[0067] S122: The throughput data of the remaining associated collection devices except the collection device with the maximum throughput data in each group of associated collection devices is removed from all received throughput data.

[0068] During data transmission, in order to reduce the performance requirements of the security host, the upload of the collection device with the maximum throughput data in the associated part of the collection device, and the temporary storage of the throughput data collected by the remaining collection devices in the cache area, the subsequent security host is idle, and the upload storage is performed, which is convenient for subsequent tracing.

[0069] S122: The throughput data of the removed collection device is stored in the cache area.

[0070] As described above, the present application provides a dynamic multi-source security system and a security method, wherein the dynamic multi-source security system comprises: a security host and a plurality of collection devices in communication connection with the security host; the transmission data packet collected by the collection device is transmitted through the transmission node on the time axis, and the throughput data A 总 of all collection devices in the same transmission node is compared with the security host throughput data A 安防 to adjust the transmission data packet, so as to meet the transmission requirements of the collection device. The batch sending mode is adopted, which reduces the number of transmission data packets sent by the collection device received by the security host at the same time, thereby reducing the demand for security host throughput data A 安防 . At the same time, A 总 > A安防 The transmission data packet is split, and the split data can also ensure accuracy, so that the sum of the new throughput data formed by the split transmission data packet is equal to A 安防 Further reduce the demand for security host throughput data A 安防 , so as to reduce the hardware configuration of the security host and reduce the overall cost of the security system.
