Fig. 1 is a block diagram of a system for implementing an alarm according to an exemplary embodiment of the present application, where fig. 1 includes an alarm device (e.g., an alarm and a camera installed in a user room) and a server and a prompter of an alarm receiving center. The alarm device can actively detect abnormal conditions and generate an alarm signal, and can also generate the alarm signal based on the triggering of pressing an alarm button by a user; the alarm receiving center generally refers to centers such as police offices, security departments, district dispatching centers and the like, a server of the alarm receiving center is used for receiving alarm information reported by each alarm device, and the server prompts workers of the alarm receiving center through a prompter. However, after acquiring the alarm information, the staff in the alarm receiving center needs to dispatch the staff in the arrangement center to issue an alarm, and usually, the alarm receiving center is a certain distance away from the emergency site, so that the staff in the alarm receiving center can take a certain time to issue an alarm and arrive at the emergency site, and thus when an alarm occurs, the prior art cannot quickly respond to the on-site alarm, the defense of a single user is weak, the on-site alarm cannot be rescued in time, and huge loss is brought to the user.
Based on this, fig. 2 is a system structure diagram of a joint defense alarm according to an exemplary embodiment shown in the present application, the server in fig. 2 receives the respective location information reported by each alarm device, and each alarm device may also send the respective device information to the server while reporting the respective location information, such as the location information of alarm device a, the location information of alarm device B, the location information of alarm device C, the location information of alarm device D, the location information of alarm device E, the location information of alarm device F, and the location information of alarm device G shown in fig. 2, if the alarm device B, the alarm device C, the alarm device D, the alarm device E and the alarm device F are determined according to the position information, and the alarm devices G are all devices around the alarm device a, and the server can determine the device information of these alarm devices as a group centered on the alarm device a. When the position of the alarm device A is in an alarm state and alarm information is generated, the alarm information is reported to the server, and the server can push the alarm information to the alarm device B, the alarm device C, the alarm device D, the alarm device E, the alarm device F and the alarm device G which are in a group and take the alarm device A as the center, so that users in the group can know the alarm information, quickly position which user alarms, and timely arrive at a scene of a case for rescue so as to quickly respond to the scene of the alarm. Meanwhile, the server can also output an alarm condition prompt of the alarm information, and after workers of the alarm receiving center know the alarm information, the workers of the dispatching and arranging center give an alarm. Therefore, based on the joint defense warning system shown in the figure 2, after the warning situations occur, a joint defense group can be rapidly formed on the site, the on-site warning situations are temporarily processed, and the loss is effectively reduced.
It should be noted that the server may establish a group centered on each alarm device for each alarm device reporting the location information. It will be understood by those skilled in the art that the number of peripheral alarm devices of the alarm device a identified above in fig. 2 is merely illustrative and not limiting in the present application.
The technical solution of the present application is explained in detail by the following specific examples.
Fig. 3 is a flowchart of an embodiment of a joint defense warning method according to an exemplary embodiment of the present application, where the joint defense warning method may be applied to the server shown in fig. 2, and the following describes an embodiment of the present application in detail with reference to the system structure diagram shown in fig. 2. As shown in fig. 3, the joint defense warning method includes the following steps:
step 301: and acquiring the equipment information of the second alarm equipment which meets the preset condition according to the distance between the received position information of the first alarm equipment and the received position information of the second alarm equipment.
In an embodiment, the server may send request information to each alarm device in the alarm receiving center, so that each alarm device reports its own location information, and when new location information is not received within a preset time range, the server acquires device information of a second alarm device that meets a preset condition according to a distance between the received location information of the first alarm device and the received location information of the second alarm device.
In an embodiment, the server may send request information to each alarm device in the alarm receiving center once every preset time period, so that each alarm device reports its own location information again, and obtains the device information of the second alarm device meeting the preset condition according to the distance between the newly received location information of the first alarm device and the newly received location information of the second alarm device, and determines the newly added second alarm device and the second alarm device of the unreported location according to the existing alarm devices in the group, then adds 1 to the statistical number of the second alarm device of the unreported location in the group, deletes the second alarm device of which the statistical number reaches the preset value from the group, and then judges whether there is an alarm device in the group whose distance from the first alarm device is greater than the distance between the first alarm device and the newly added second alarm device, and if so, updating the group by using the newly added equipment information of the second alarm equipment.
Since the alarm devices are usually arranged in the rooms of the users, the positions of the alarm devices may change due to the moving of the users, and therefore, each alarm device can be requested to report a bit again every preset time period to ensure the validity of the grouping. The preset value can be set according to actual experience, if the times of non-reporting reaches the preset value, the alarm device is off-line and can be deleted from the grouping, and the problem of mistaken deletion caused by temporary network faults can be avoided through the preset value.
In an exemplary scenario, as shown in fig. 2, the group includes an alarm device B, an alarm device C, an alarm device D, an alarm device E, an alarm device F, an alarm device G, and an alarm device a, and the alarm device a is a central device, assuming that after a preset time period, the alarm devices that the server receives the reported location information include the alarm device a, the alarm device C, the alarm device D, the alarm device E, the alarm device F, the alarm device G, and the alarm device H, if the alarm device a is taken as a center, the device information of the alarm device that meets the preset condition includes the alarm device C, the alarm device D, the alarm device E, the alarm device F, the alarm device G, and the alarm device H according to the distance between the location information of the alarm device a and the location information of other alarm devices, because the alarm device B in the group does not report location, therefore, the number of times of statistics of the alarm device B is increased by 1, and if the number of times of statistics reaches a preset value, the alarm device B is deleted from the group. Because the alarm device H is a newly added alarm device, if the distance between the alarm device a and the alarm device G is greater than the distance between the alarm device a and the alarm device G, the device information of the alarm device G in the group is replaced with the device information of the alarm device H.
For the process of step 301, for example, refer to the following description of the embodiment shown in fig. 4A, and details will not be provided here.
Step 302: and determining the grouping taking the first alarm device as the center according to the acquired device information of the second alarm device.
In one example, the server may record the obtained device information of the second alarm device and the device information of the first alarm device in the grouping information, and mark the first alarm device as the center device.
The device information recorded in the packet may be a unique identifier, an IP (Internet Protocol) address, of each alarm device.
In an exemplary scenario, as shown in fig. 2 above, assuming that distances between the location of the alarm device a and the locations of the alarm device B, the alarm device C, the alarm device D, the alarm device E, the alarm device F, and the alarm device G respectively satisfy preset conditions, the alarm devices may be determined as a group centered on the alarm device a.
Step 303: when the alarm information reported by the first alarm device is received, the alarm information is sent to the second alarm devices in the groups, so that the second alarm devices output alarm condition prompts aiming at the alarm information.
In an embodiment, after the server sends the alarm information reported by the first alarm device to the second alarm device in the group with the first alarm device as the center, the second alarm device outputs an alarm condition prompt aiming at the alarm information, and a user of the second alarm device knows the alarm condition prompt, quickly locates which user alarms, and timely arrives at a case site to quickly respond to the on-site alarm condition. Therefore, after the alarm condition occurs, a joint defense group can be rapidly formed on site, the site alarm condition is temporarily processed, and the loss is effectively reduced. The alarm information may include alarm occurrence address information, alarm type information, case-sending site video information, and the like.
In an embodiment, the server may sequentially send the alarm information to the corresponding second alarm devices in the order from small to large of the distance between the first alarm device and the second alarm device in the group. Therefore, the nearest user can know the alarm information first and arrive at the scene of a case first for rescue.
In an embodiment, the server may further determine whether the first alarm device belongs to another group, and if so, send the alarm information to a second alarm device in another group.
The server can send the alarm information to a second alarm device in a plurality of groups to enlarge the pushing range of the alarm information.
In an embodiment, the server may further send the alarm information to the second alarm device in the group every preset time, and stop sending until the sending times reaches the preset times. Therefore, the mode of increasing the pushing frequency to the alarm equipment in the group is adopted, and the situation that the user misses the warning prompt is avoided.
It should be noted that the server may also receive terminal information of a terminal associated with the first alarm device and add the terminal information to the grouped information, so that after the alarm information is sent to the second alarm device in the group, the alarm information may also be sent to the terminal added in the group.
The terminal associated with the first alarm device can be a terminal of a relative, a friend, a community, a property and the like, so that when an alarm occurs, the relative, the friend, the community, the property and the like of a user to which the first alarm device belongs can acquire alarm information and take some temporary rescue measures.
It should be further noted that the server may also send the grouped information to the first alarm device, so that the first alarm device sends the alarm information to the second alarm device in the group after generating the alarm information according to the detected trigger signal.
Based on the scenario shown in step 302, when the server receives the alarm information reported by the alarm device a, the server may send the alarm information to the alarm devices B, C, D, E, F, and G in the group, respectively, and users of the alarm devices may arrive at the scene of a case in time for rescue after learning the alarm condition.
In this embodiment, the server of the alarm receiving center may obtain the device information of the second alarm device that meets the preset condition according to the distance between the received position information of the first alarm device and the received position information of the second alarm device, and determine a group that takes the first alarm device as a center according to the obtained device information of the second alarm device, so that when the alarm information reported by the first alarm device is received, the alarm information may be sent to the second alarm device in the group, so that the second alarm device outputs an alarm prompt for the alarm information, and the server may locally output an alarm prompt for the alarm information. Based on the description, the second alarm devices meeting the conditions are divided into the groups taking the first alarm devices as the center, and when the alarm information reported by the first alarm devices is received, the alarm information can be pushed to the second alarm devices in the groups, so that other members in the groups can know the alarm information and timely arrive at a case scene, the on-site alarm can be quickly responded, the self-defense capability of users is enhanced, and the loss is effectively reduced in advance.
Fig. 4A is a flowchart of another joint defense warning method according to an exemplary embodiment of the present application, and based on the embodiment shown in fig. 3, this embodiment exemplarily illustrates how to obtain the device information of the second warning device meeting a preset condition according to the distance between the received location information of the first warning device and the received location information of the second warning device, as shown in fig. 4A, the joint defense warning method may include the following steps:
step 401: a distance between the location information of the first alert device and the received location information of the second alert device is determined.
Step 402: and judging whether a second alarm device with the distance smaller than a preset search threshold exists, if so, executing step 403, and if not, executing step 404.
Step 403: and determining the equipment information of at least one second alarm equipment with the distance smaller than the search threshold value as the equipment information of the second alarm equipment meeting the preset condition.
In an embodiment, the server may compare the number of the second alarm devices whose distance is less than the search threshold with a first preset number, and if the number of the second alarm devices whose distance is less than the search threshold is greater than the first preset number, sequentially select the first preset number of the second alarm devices according to a sequence from small to large of the distance, and determine the device information of the selected second alarm devices as the device information of the second alarm devices meeting the preset condition; and if the number of the second alarm devices with the distances smaller than the search threshold is not larger than the first preset number, determining the device information of the second alarm devices with the distances smaller than the search threshold as the device information of the second alarm devices meeting the preset conditions.
In an embodiment, the server may also directly determine the device information of the second alarm device whose distance is less than the search threshold as the device information of the second alarm device that meets the preset condition.
Step 404: and expanding the search threshold, judging whether a second alarm device with the distance smaller than the expanded search threshold exists, if so, executing the step 405, and if not, executing the step 406.
In an embodiment, the server may enlarge the search threshold by increasing the search threshold by a preset step size, where the preset step size may be set according to practical experience, for example, the preset step size may be set to 0.5 times of the search threshold.
Step 405: and determining the equipment information of at least one second alarm equipment with the distance smaller than the expanded search threshold value as the equipment information of the second alarm equipment meeting the preset condition.
In an embodiment, if the number of the second alarm devices with the distance smaller than the expanded search threshold is larger than a second preset number, sequentially selecting the second alarm devices with the second preset number according to the sequence from small to large of the distance, and determining the device information of the selected second alarm devices as the device information of the second alarm devices meeting the preset conditions; and if the number of the second alarm devices with the distances smaller than the expanded search threshold is not larger than a second preset number, determining the device information of the second alarm devices with the distances smaller than the expanded search threshold as the device information of the alarm devices meeting the preset conditions.
Wherein the second preset number is less than or equal to the first preset number. Since the first predetermined number is for the second alarm devices determined by the preset search threshold, which are closest to the first alarm devices, and the second predetermined number is for the second alarm devices determined by the expanded search threshold, the first predetermined number may be set larger than the second predetermined number.
In an embodiment, the server may also directly determine the device information of the second alarm device whose distance is smaller than the expanded search threshold as the device information of the second alarm device that meets the preset condition.
Step 406: and continuing to expand the search threshold until the expanded search threshold reaches a preset maximum threshold, and stopping expanding the search threshold.
In an exemplary scenario, fig. 4B-4D are diagrams illustrating a deterministic grouping shown in the present application according to the embodiment shown in fig. 4A. As shown in fig. 4B, the preset search threshold is L, and the distance between the device a and the device B, the distance between the device a and the device C, and the distance between the device a and the device D are all smaller than the preset search threshold L, assuming that the first preset number is 8, since the number of devices whose distances are smaller than the search threshold L is 3, the device B, the device C, and the device D may be determined as devices that meet the preset condition; as shown in fig. 4C, distances between the device a and the devices B, C, D, I, J, K, L, M, and N are all smaller than a preset search threshold L, and since the number of the devices whose distances are smaller than the search threshold L is 9 and greater than the first preset number 8, the first preset number of 8 devices may be sequentially selected in the order from small to large according to the distances between the device a and the devices: device B, device C, device D, device I, device K, device L, device M, and device N (device J is discarded since the distance between device J and device a in fig. 4C is the largest), and determine the device information of these selected devices as the device information of the alarm device that meets the preset condition; as shown in fig. 4D, if there is no device whose distance is smaller than the search threshold L, the search threshold is expanded to L +0.5L, and the distance between the device a and the device E, the distance between the device a and the device F, the distance between the device a and the device G, and the distance between the device a and the device H are all smaller than the expanded search threshold L +0.5L, and assuming that the second preset number is 4, since the number of devices whose distances are smaller than the search threshold L +0.5L is 4, the device E, the device F, the device G, and the device H may be determined as devices that meet the preset condition.
In this embodiment, after determining the distance between the location information of the first alarm device and the received location information of the second alarm device, the server first determines whether there is a second alarm device whose distance is smaller than a preset search threshold, if so, directly determines the device information of at least one second alarm device whose distance is smaller than the search threshold as the device information of the second alarm device meeting the preset condition, if not, enlarges the search threshold, and continues to determine whether there is a second alarm device whose distance is smaller than the enlarged search threshold, and if so, determines the device information of at least one second alarm device whose distance is smaller than the enlarged search threshold as the device information of the second alarm device meeting the preset condition; otherwise, continuing to expand the search threshold until the expanded search threshold reaches a preset maximum threshold, and stopping expanding the search threshold. Therefore, any number of users around the united site can be divided into one group, and emergency united protection can be realized when an alarm occurs.
