Specific embodiments of the present application have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.
Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 1 is a schematic view of a scenario of a monitoring method provided in an embodiment of the present application, as shown in fig. 1, where the data room 10 includes a plurality of rooms, for example, room 1, room 2, room 3, room 4, etc., and each room is provided with a cabinet array, in which a computer device can be loaded. To increase the confidentiality of the machine rooms, each machine room is provided with an access control 12. The staff can open entrance guard 12 through the mode of punching the card, enters into the computer lab, maintains the management to the computer equipment in the computer lab.
In practical life application, in order to save labor cost and improve the maintenance efficiency and automation level of a machine room, a robot 11 is adopted to execute operation and maintenance tasks in a general data machine room to assist or replace workers. When the robot 11 is used for inspection across machine rooms, the robot needs to enter from one machine room to the other machine room, and at this time, the robot needs to remotely control the opening and closing of the machine room entrance guard 12. The door control 12 is an automatic door, and a robot door control module is added to the door control system, namely, a robot can control the door control 12 to be opened and closed through the robot door control module. However, in the process that the robot controls the entrance guard 12 to open and the robot enters the entrance guard 12, illegal personnel can easily use the time of opening the door to illegally enter the machine room, so that data in the machine room is leaked, and the information security of the machine room is threatened.
The prior art mainly adopts two ways to monitor illegal intrusion, one way is to install a camera at a machine room gate, and when illegal intrusion exists, the monitoring video can be reviewed or workers are arranged to continuously review the monitoring video in real time, so that illegal intrusion can be found in time. The mode consumes manpower and is easy to overlook, and when the staff has visual fatigue, illegal staff can use the robot as a shield to avoid the check of the staff; and the monitoring video can not be seen back in time to find illegal intrusion, and the delay exists. The other mode is to install an infrared emitter and an infrared receiver on the entrance guard, and the infrared sensor can be triggered when the entrance guard intrudes, so that the monitoring purpose is realized. However, the method still has a loophole, so that the monitoring effect is not ideal, for example, an illegal person can pass through the entrance guard side by side with the robot, and the illegal intrusion method cannot be detected by the sensor.
In view of the above problems, embodiments of the present application provide a monitoring method, an apparatus, an access control system, and a readable storage medium, where when an access control is opened, a distance between a target object passing through the access control and a preset position point on a side edge of the access control is obtained, a size characteristic of the target object is determined, and then whether the target object is a target object with door opening authority is determined by using the size characteristic, so that a situation that an illegal person and the target object pass through the access control side by side can be monitored, monitoring accuracy is improved, and automatic monitoring of illegal intrusion is realized.
The technical scheme of the application is described in detail through specific embodiments. It should be noted that the following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a schematic flow chart of a monitoring method according to an embodiment of the present application. The monitoring method can be applied to an access control system. As shown in fig. 2, the monitoring method specifically may include the following steps:
s201, controlling the door control to be opened in response to a door opening request initiated by a target object.
The target object may be a worker or a robot, and the worker may initiate a door opening request by swiping a card to open the door. The robot can initiate a door opening request through a robot entrance guard module arranged on the entrance guard system, and remotely control the opening and closing of the entrance guard.
For example, if the target object is a robot, the robot may initiate the door opening request through a wireless communication manner, such as a wireless bluetooth communication manner, with the access control system. After the door control system receives the door opening request, whether the robot initiates or authorized staff initiates through card swiping is judged according to the door opening request, and then the door control system opens the door.
Optionally, taking an access control in the data machine room as an example, the access control comprises two types of access control, wherein one type of access control is a cold air channel access control, and the other type of access control is an access control between the machine rooms.
In one embodiment, if the robot passes through the gate inhibition smoothly, a gate-closing request can be initiated to the gate inhibition system again, so that the gate inhibition system controls the gate inhibition to be closed.
Optionally, if the illegal intrusion exists, when the robot does not pass through the entrance guard smoothly, a door closing request can be initiated to the entrance guard system, so that the entrance guard system controls the entrance guard to close, and information leakage caused by the illegal intrusion is avoided.
S202, acquiring distance data between a target object passing through the entrance guard and a preset position point.
The side of the access control device is provided with at least one preset position point. For example, preset position points can be set on four sides of the left side, the right side, the top and the bottom of the entrance guard.
In this embodiment, the object passing through the entrance guard may be a robot, or may be an illegal person who intrudes illegally, or the like. Fig. 3 is a side view of a robot according to an embodiment of the present application, and as shown in fig. 3, the robot includes a table 31 provided at a front end portion of the robot, a link 32 provided at a middle portion of the robot, and a body 33 provided at a rear end portion of the robot. Wherein the table 31 is connected to the body 33 via a link 32, and the robot can move on the ground. The height of the table 31 is, for example, 40-45 cm.
Illustratively, fig. 4 is a cross-sectional view of a robot according to an embodiment of the present application, and as shown in fig. 4, the width of the table 41, the width of the link 42, and the width of the body 43 are different from one another. Illustratively, the width of the table 41 may be 25 cm, the width of the link 42 may be 6 cm, and the width of the body 43 may be 40 cm. If the preset position point is set on the right side of the door control, when the robot passes through the door control, the distance between the workbench 41 and the preset position point, the distance between the connecting rod 42 and the preset position point, and the distance between the body 43 and the preset position point are different, so that the size characteristics of the robot can be obtained.
For example, fig. 5 is a schematic diagram of a robot passing through an entrance guard according to an embodiment of the present application, as shown in fig. 5, if a preset position point a and a preset position point B are respectively set on a left side 54 and a right side 55 of the entrance guard, when the robot passes through the entrance guard, a distance between a workbench 51 and the preset position point a is L1, and a distance between the workbench and the preset position point B is L2. The link 52 is located at a distance L3 from the preset position point a and at a distance L4 from the preset position point B. The body 53 is located at a distance L5 from the preset position point a and at a distance L6 from the preset position point B.
Fig. 6 is a schematic diagram of an embodiment of an access control by an illegal person according to an embodiment of the present application, as shown in fig. 6, if a preset position point a and a preset position point B are respectively set on a left side 61 and a right side 62 of the access control, a distance between the illegal person and the preset position point a is L7, and a distance between the illegal person and the preset position point B is L8.
Fig. 7 is a schematic diagram of an embodiment two of an access control by an illegal person according to the present application, as shown in fig. 7, if a preset position point a and a preset position point B are respectively set on a left side 71 and a right side 72 of the access control, and the illegal person and the robot 70 pass through the access control side by side, the illegal person and the robot can be regarded as an integral object, and the distance between the object and the preset position point a is L9, and the distance between the object and the preset position point B is L10.
For example, a distance measuring sensor may be disposed at a position marked by the preset position point, and the above L1-L10 is acquired by the distance measuring sensor as distance data.
For example, one preset position point may be set only on the left side or the right side of the entrance guard, a plurality of preset position points may be set on the left side or the right side of the entrance guard, and one or more preset position points may be set on the top and/or the bottom of the entrance guard.
The distance measuring sensor can be arranged at the position marked by each preset position point so as to acquire distance data between a target object passing through the entrance guard and the preset position point.
Alternatively, the ranging sensor may be an ultrasonic ranging sensor, a laser ranging sensor, or the like.
S203, determining the size characteristics of the object passing through the entrance guard according to the distance data.
In this embodiment, the size characteristics of the object passing through the entrance guard can be accurately determined by the distance data L1-L10 shown in fig. 5 to 7.
Wherein dimensional characteristics may be used to describe the width or height of the object. The size characteristics of the target object can be obtained through calculation according to a preset calculation formula. For example, according to preset passing width and distance data of the entrance guard, the width of the target object is calculated.
Illustratively, taking the robot passing through the entrance guard as an example, the width of the front end part (i.e., the workbench) of the robot is the total width L of the entrance guard minus L1 and L2. The width of the middle part (namely the connecting rod) of the robot is the total width L of the entrance guard minus L3 and L4. The width of the end part (i.e., the body) of the robot is the total width L of the entrance guard minus L5 and L6.
Alternatively, the dimensional characteristics of the target may include at least one of a width of a front end portion, a width of a middle portion, and a width of a distal end portion of the target.
For example, a preset position point may be set on a top side of the entrance guard, and a ranging sensor may be set at a position marked by the preset position point, when the target object passes through the entrance guard, distance data of the top (e.g., the head) of the target object from the preset position point may be measured by the ranging sensor, and then, according to the height of the entrance guard and the distance data, the height of the target object may be calculated as a size feature of the target object.
S204, obtaining a monitoring result according to the size characteristics of the target object and preset size data.
The monitoring result is used for indicating whether the target object is a target object or not.
In this embodiment, the size characteristic of the target object may be a width or a height of the target object, and the preset size data may be size data of the target object having access right, where the width or the height of the target object is included.
When the size characteristic of the target object is the width of the target object, the preset size data corresponds to the width of the target object, and when the size characteristic of the target object is the height of the target object, the preset size data corresponds to the height of the target object. By comparing the width of the target object with the width of the target object, whether the target object is the target object can be determined.
In an embodiment, taking a target object as a robot as an example, the door control system may store a size characteristic of the robot, where the size characteristic of the robot may be at least one of a width of a front end portion of the robot, a width of a middle portion of the robot, and a width of a tail end portion of the robot, and if the target object is determined to be the robot, the size characteristic of the robot may be extracted as preset size data.
According to the embodiment of the application, the width or the height of the object can be determined by collecting the distance between the object passing through the entrance guard and the preset position point, and the object passing through the entrance guard can be judged whether to be the object or not as the size characteristic of the object, so that the entrance guard can be accurately monitored by the illegal object and the robot in parallel or along with the robot, the monitoring accuracy is improved, meanwhile, the automation can be realized, and the manual monitoring cost is reduced.
Fig. 8 is a schematic flow chart of a second embodiment of the monitoring method provided by the embodiment of the present application, as shown in fig. 8, if a first location point is provided on the left side of the entrance guard and a second location point is provided on the right side of the entrance guard, the monitoring method may include the following steps:
s801, controlling the opening of an access control in response to an opening request initiated by a target object.
S802, acquiring a first distance between a target object passing through the entrance guard and a first position point and a second distance between the target object and a second position point.
S803, obtaining distance data according to the first distance and the second distance.
S804, determining the size characteristics of the object passing through the entrance guard according to the distance data.
S805, obtaining a monitoring result according to the size characteristics of the target object and the preset size data.
The monitoring result is used for indicating whether the target object is a target object or not.
Specifically, the object passing through the entrance guard may be a target object, or may be an illegal person making an illegal break-in, or may be an integral body formed by the target object and the illegal person, and at this time, the target object and the illegal person pass through the entrance guard side by side.
In this embodiment, the first distance is used to indicate the linear distance from the target object to the first location point on the left side of the entrance guard, and the second distance is used to indicate the linear distance from the target object to the second location point on the right side of the entrance guard. The distance data refers to two sets of values, a first distance and a second distance.
In this embodiment, the size feature refers to the width of the target object, and the preset size data may be the width of the target object.
In some embodiments, the first location point and the second location point may be at different levels.
For example, the heights of the first location point and the second location point may be selected according to the size characteristics of the target object. For example, the workbench of the robot is about 40-45 cm away from the ground, the first position point can be arranged at the height of 41 cm, the second position point can be arranged at the position of 43 cm, the first distance measuring sensor is arranged at the first position point, and the second distance measuring sensor is arranged at the second position point, so that the widths of the workbench, the connecting rod and the body can be conveniently acquired. Meanwhile, the ranging sensors at different heights can also prevent the optics emitted by the ranging sensor at the first position point from irradiating the ranging sensor at the second position point, so that false detection is prevented, and the ranging accuracy is improved.
According to the embodiment of the application, the position points are respectively arranged on the left side and the right side of the access control, so that the distance between the object passing through the access control and the left position point and the distance between the object and the right position point can be acquired, the width of the object can be acquired, illegal personnel intrusion can be accurately monitored, and the illegal personnel can be prevented from using the object and can pass through the access control side by side.
Further, in some embodiments, the step S802 may be specifically implemented by the following steps:
determining the positions of the front end part, the middle part and the tail end part of a target object passing through the entrance guard;

Meanwhile, the robot can initiate a door closing request to the access control system according to the alarm prompt, and the access control system is controlled to be closed.
According to the embodiment of the application, by outputting the alarm prompt, the staff can timely find illegal intrusion, and the monitoring effect is improved.
