Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Several embodiments of the invention are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Example one
Referring to fig. 1, a self-constriction behavior monitoring method applied to monitoring in a first embodiment of the present invention is shown, and the self-constriction behavior monitoring method applied to monitoring in the first embodiment of the present invention can be implemented by software and/or hardware, and specifically includes steps S01 to S03.
Step S01, acquiring detection data of the grating detector disposed at the high hanging point in the monitoring center.
The high hanging points can be, but are not limited to, high windows, protective nets, monitoring equipment supports and the like, and the escorting personnel can throw the ropes or the cloth strips at the high hanging points to hang the ropes or the cloth strips at the high hanging points, so that the self-constriction is realized. Therefore, in this embodiment, the grating detector is arranged at the high-place suspension point, so as to detect suspicious objects such as ropes and cloth strips entering the high-place suspension point by using the grating detector and output detection data, where the detection data may specifically be a detection distance from the suspicious object to the grating detector or a light source receiving interrupt signal generated when the suspicious object blocks detection light.
Step S02, according to the detection data of the grating detector, judging whether the grating detector detects suspicious objects at the high suspension point. Wherein, when the grating detector detects the suspicious object at the high suspension point, the step S03 is executed; when the grating detector does not detect the suspicious object at the high suspension point, the grating detector does not act and continues to monitor.
In some optional cases of this embodiment, step S02 may specifically include:
judging whether the grating detector continuously detects an object at the high suspension point within a preset time according to the detection data of the grating detector;
and if so, judging that the grating detector detects the suspicious object at the high suspension point.
The preset time can be 3-5 seconds, because when a rope, a cloth strip and other suspicious objects are hung at a high hanging point, the grating detector can continuously detect the suspicious objects, otherwise, when the grating detector continuously detects a certain object at the high hanging point for 3-5 seconds, the object is judged to be the suspicious object, and the object is probably the rope, the cloth strip and the like hung at the high hanging point. That is, under this condition, only when the duration that the grating detector detected the object and surveyed this object reached preset time, just can judge this object as suspicious object, avoid an thing to follow eminence and hang some through, if the mosquito flies through from eminence and hangs some, just judge the action of turning into a wind certainly, can effectively reduce the erroneous judgement.
And step S03, judging that the self-constriction behavior exists at the high hanging point.
It can be understood that when the self-constriction behavior at the high-altitude hanging point is judged to exist at present, the self-constriction early warning (such as alarming, character prompting and/or light prompting) can be sent out, so that the personnel monitoring the current value can rapidly arrive at the high-altitude hanging point to check whether the self-constriction behavior really exists, and the self-constriction behavior can be effectively prevented and restrained from happening when escort personnel utilize the high-altitude hanging point to constrict the self-constriction behavior.
In summary, in the self-constriction behavior monitoring method applied to the monitoring center in the above embodiments of the present invention, the grating detector is arranged at the high hanging point in the monitoring center, and whether the suspicious object is detected by the grating detector at the high hanging point is continuously analyzed according to the detection data of the grating detector, and once the suspicious object is found, the self-constriction behavior at the high hanging point is immediately determined, so that the occurrence of the self-constriction at the high hanging point by escort personnel can be effectively prevented.
Example two
The second embodiment of the present invention also provides a self-constriction behavior monitoring method applied to monitoring a house, and the self-constriction behavior monitoring method in this embodiment is different from the self-constriction behavior monitoring method in the first embodiment in that:
referring to fig. 2-3, in the present embodiment, the grating detector is specifically disposed below the high suspension point (e.g., 0.5m below), the grating detector specifically includes a plurality of rows of light emitters and a plurality of rows of receivers disposed along the height direction, the light emitters and the receivers are disposed in a one-to-one correspondence, so that the light sources (e.g., infrared light) emitted by the light emitters can be received by the corresponding receivers, and the light emitters and the corresponding receivers in the same row are in the same horizontal plane. In particular implementations, the emitters and receivers may be disposed on walls on both sides of a high hanging point (e.g., a window), and a plurality of emitters and receivers may be disposed in the same row, resulting in a wider coverage of the grating detector.
Based on the specific arrangement and structure of the grating detector, the step of judging whether the grating detector detects the suspicious object at the high suspension point or not according to the detection data of the grating detector comprises the following steps:
judging whether a receiver with interrupted light source receiving continues to exist within a preset time;
and if so, judging that the grating detector detects the suspicious object at the high suspension point.
It should be understood that when a suspicious object is hung at a high hanging point, the suspicious object can block part of the light source emitted by the light emitter, so that the light source receiving of the receiver at the corresponding position is interrupted, and conversely, when the receiver with the light source receiving interruption continues to exist within 3-5s, the suspicious object is judged to be hung at the high hanging point.
Further, before the step of determining that there is a self-constriction behavior at the high hanging point (i.e., step S03), the self-constriction behavior monitoring method further includes:
judging whether the suspicious object shakes or not according to the distribution of receivers with interrupted light source receiving among the receivers in the same row, wherein the light source is emitted by a light emitter;
and if the shaking exists, judging that the self-constriction behavior exists at the high hanging point. If the shaking does not exist, the monitoring is not operated and is continued.
That is, in this embodiment, a condition for determining the self-constriction behavior is further added, that is, after the grating detector detects the suspicious object at the high hanging point, whether the suspicious object has a shake or not is determined according to the distribution of the receivers with interrupted light source reception among the receivers in the same row, and if the suspicious object has a shake, the self-constriction behavior at the high hanging point is determined. The principle is as follows: as shown in fig. 2, after the rope or the cloth is hung at a high hanging point, the rope or the cloth may shake, particularly at the moment when a person hangs on the rope or the cloth and starts to perform a self-constriction, the rope or the cloth may shake more severely, and at this moment, a plurality of receivers with interrupted light source reception may exist, and the receivers are adjacent to each other, so that whether the suspicious object shakes or not may be determined according to the distribution of the receivers with interrupted light source reception, and if the suspicious object shakes, the self-constriction behavior may be possible. Therefore, in the embodiment, by combining the characteristic, a judgment condition of the self-constriction behavior is increased, so that the reliability of the judgment of the self-constriction behavior is improved, and the misjudgment is greatly reduced.
Further, in some optional cases of the present embodiment, before the step of determining that there is a self-constriction behavior at the high hanging point (step S03), the method further includes:
judging whether the motion track of the suspicious object is a preset track or not according to the distribution of receivers with interrupted light source reception among a plurality of rows of receivers;
if the track is a preset track; and judging that the self-constriction behavior exists at the high hanging point. And if the track is not the preset track, the monitoring is not carried out and the monitoring is continued.
The preset track is that the high-altitude suspension point moves to the highest point and then falls from the highest point. As shown in fig. 3, when the suspicious object (such as a rope or a cloth) executes the preset trajectory, the suspicious object may pass through the grating detector from bottom to top, and then pass through the grating detector from top to bottom again, so that the receivers with interrupted light source reception may be distributed from bottom to top and then from top to bottom, and the suspicious object may be determined to have the preset trajectory when the distribution of the receivers with interrupted light source reception satisfies the change rule.
That is, in this embodiment, a condition for determining the self-constriction behavior is further added, that is, after the grating detector detects the suspicious object at the high hanging point, it is further determined whether the movement trajectory of the suspicious object moves upward to the highest point and then falls from the highest point, and if so, it is determined that the self-constriction behavior exists at the high hanging point. The principle is as follows: as shown in fig. 3, since the rope or the cloth strip must be highly thrown to the high hanging point, and the trajectory of the high throw is from bottom to top to fall after moving to the highest point, the present embodiment combines the feature to increase the judgment condition of the self-constriction behavior, thereby improving the accuracy and reliability of the judgment of the self-constriction behavior, and greatly reducing the misjudgment.
In specific implementation, the predetermined trajectory determination mechanism and the sway determination mechanism may be combined together, and may be executed simultaneously or sequentially, or the predetermined trajectory determination mechanism and the sway determination mechanism may be separately used.
In addition to this, after the step of determining that there is a self-constriction behavior at the high hanging point, the self-constriction behavior monitoring method may further include:
and sending out a self-constriction behavior early warning prompt, wherein the early warning prompt contains the positioning information of the high hanging point.
The early warning prompt of the self-constriction behavior can be but is not limited to voice alarm, text prompt and/or light prompt, and the early warning prompt contains positioning information of a suspension point at a high position, such as a No. 1 window in the north of a prison, so that a prison-duty person can accurately position the self-constriction place and quickly arrive at the site to timely suppress the self-constriction behavior. In specific implementation, the high hanging point and the positioning information thereof and the identification information (such as the detector model, the serial number, the communication identification code and the like) of the grating detector can be stored in an associated manner to form a mapping table, and when any detection data is obtained, the corresponding high hanging point and the positioning information thereof can be determined by looking up the mapping table according to the identification information of the detection data.
