In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a scene schematic diagram of a monitoring method provided in an embodiment of the present application, and as shown in fig. 1, in a data room 10 in an application scene of this embodiment, the data room 10 includes a plurality of rooms, for example, a room 1, a room 2, a room 3, a room 4, and the like, each room is provided with a cabinet array, and a computer device may be loaded in the cabinet array. In order to improve the security of the machine rooms, each machine room is provided with an entrance guard 12. The staff can open entrance guard 12 through the mode of punching the card, enter into the computer lab, maintain the computer equipment in the computer lab and manage.
In actual life application, in order to save labor cost and improve the efficiency and automation level of machine room maintenance, a robot 11 is adopted in a general data machine room to execute operation and maintenance tasks, and assist or replace workers. When the robot 11 is used for cross-room routing inspection, the robot needs to enter another room from one room, and at the moment, the robot is required to be capable of remotely controlling the opening and closing of the room access control 12. And entrance guard 12 sets up to the automatically-controlled door, and it adds has a robot entrance guard module, and the robot can come to control entrance guard 12 switches through robot entrance guard module promptly. However, in the process that the robot controls the entrance guard 12 to be opened and the robot enters the entrance guard 12, illegal personnel easily break into the machine room by using the door opening opportunity, so that data in the machine room is leaked, and the information safety of the machine room is threatened.
In the prior art, two modes are mainly adopted for monitoring the illegal intrusion, one mode is that a camera is arranged at the door of a machine room, when the illegal intrusion occurs, the monitoring video can be reviewed or workers can be arranged to continuously check the monitoring video in real time, and the illegal intrusion is discovered in time. The mode consumes manpower and is easy to miss, and when workers have visual fatigue, illegal people can use the robot to shield to avoid the checking of the workers; however, when the monitoring video is viewed again, illegal intrusion cannot be found in time, and time delay exists. The other mode is that an infrared transmitter and an infrared receiver are installed on the entrance guard, and when the entrance guard is intruded illegally, an infrared sensor is triggered to achieve the purpose of monitoring. However, the method still has a leak, 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 mode cannot be detected by the sensor.

The technical solution of the present application will be described in detail below with reference to specific examples. It should be noted that the following specific 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 flowchart of a monitoring method according to a first embodiment of the present application. The monitoring method can be applied to an access control system. As shown in fig. 2, the monitoring method may specifically include the following steps:
s201, responding to a door opening request initiated by a target object, and controlling the door access to be opened.
For example, the target object may be a worker or a robot, and the worker may initiate a door opening request to open a door by swiping a card. The robot can initiate a door opening request through a robot entrance guard module arranged on the entrance guard system, and the opening and closing of the entrance guard are controlled remotely.
For example, if the target object is a robot, the robot may initiate a door opening request in a wireless communication manner with the access control system, for example, a communication manner such as wireless bluetooth. After the door control system receives the door opening request, whether the robot is initiated or an authorized worker is initiated by swiping a card is judged according to the door opening request, and then the door control is opened.
Optionally, taking the access control in the data machine room as an example, the access control includes two types, one type is a cold air duct access control, and the other type is an access control between machine rooms.
In an implementation mode, if the robot passes through the entrance guard smoothly, the robot can initiate a door closing request to the entrance guard system, so that the entrance guard system controls the entrance guard to close.
Optionally, if there is an illegal intrusion, the robot may also initiate a door closing request to the access control system when not passing through the access control smoothly, so that the access control system controls the access control to close, and information leakage caused by the illegal intrusion is avoided.
S202, obtaining distance data between a passing target object in the entrance guard and a preset position point.
Wherein, the side of entrance guard is provided with at least one and predetermines the position point. For example, the preset position points can be arranged on four sides of the left side, the right side, the top, the bottom and the like of the entrance guard.
In this embodiment, the target object passing through the entrance guard may be a robot, 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 invention, and as shown in fig. 3, the robot includes a table 31 disposed at a front end portion of the robot, a link 32 disposed at a middle portion of the robot, and a body 33 disposed at a distal end portion of the robot. Wherein, the workbench 31 is connected with the body 33 through the connecting rod 32, and the robot can move on the ground. Illustratively, the height of the table 31 is 40-45 centimeters.
Exemplarily, fig. 4 is a cross-sectional view of the robot provided in the embodiment of the present application, and as shown in fig. 4, a width of the working platform 41, a width of the connecting rod 42, and a width of the body 43 are different from each other. Illustratively, the width of table 41 may be 25 cm, the width of connecting rod 42 may be 6 cm, and the width of body 43 may be 40 cm. If predetermine the position point setting on entrance guard's right side, when the robot passes through entrance guard, this will lead to the distance of workstation 41 distance predetermined position point, the distance of connecting rod 42 distance predetermined position point, the distance diverse of body 43 distance predetermined position point to can obtain the size characteristic of robot.
For example, fig. 5 is a schematic view of the robot passing through the door according to the embodiment of the present application, and as shown in fig. 5, if a preset position point a and a preset position point B are respectively disposed on the left side 54 and the right side 55 of the door, when the robot passes through the door, a distance from the workbench 51 to the preset position point a is L1, and a distance from the workbench to the preset position point B is L2. The link 52 is spaced apart from the predetermined position point a by a distance L3 and from the predetermined position point B by a distance L4. The distance from the body 53 to the predetermined position point a is L5, and the distance from the body to the predetermined position point B is L6.
Fig. 6 is a schematic diagram of an illegal person passing through a first access control embodiment provided in the embodiment of the present application, and as shown in fig. 6, if a preset position point a and a preset position point B are respectively disposed on the left side 61 and the 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 illegal person passing through an entrance guard embodiment two provided by the embodiment of the present application, and as shown in fig. 7, if a preset position point a and a preset position point B are respectively arranged on a left side 71 and a right side 72 of the entrance guard, and the illegal person and the robot 70 pass through the entrance guard side by side, the illegal person and the robot can be regarded as an integral target object, a distance from the target object to the preset position point a is L9, and a distance from the target object to the preset position point B is L10.
For example, a distance measuring sensor may be disposed at the position marked by the preset position point, and the above L1-L10 may be collected by the distance measuring sensor as the distance data.
For example, one preset position point may be set only on the left side or the right side of the access control, multiple preset position points may be set on the left side or the right side of the access control, and one or more preset position points may be set on the top and/or the bottom of the access control.
The position marked by each preset position point can be provided with a ranging sensor so as to acquire distance data between a passing target object in 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 passing target object in the entrance guard according to the distance data.
In the present embodiment, the size characteristics of the objects passing through the door access can be accurately determined by the distance data L1-L10 in fig. 5 to 7.
Wherein, the dimension characteristic can be used for describing the width or height of the target object. The size characteristic of the target object can be obtained through calculation by a preset calculation formula. For example, the width of the target object is calculated according to the preset passing width and distance data of the entrance guard.
For example, taking the robot as an example of passing through a gate, the width of the front end part (i.e. the workbench) of the robot is the total width L of the gate minus L1 and L2. The width of the middle part (i.e. 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 door access minus L5 and L6.
Alternatively, the dimensional characteristic of the object may include at least one of a width of the front portion, a width of the middle portion, and a width of the end portion of the object.
For example, a preset position point may be further disposed on the top side of the door lock, and a distance measuring sensor may be disposed at a position marked by the preset position point, when the target object passes through the door lock, distance data of the top (e.g., the head) of the target object from the preset position point may be obtained through measurement by the distance measuring sensor, and then the height of the target object may be obtained through calculation according to the height of the door lock and the distance data, and the height is used as a size characteristic of the target object.
And S204, obtaining a monitoring result according to the size characteristic of the target object and preset size data.
The monitoring result is used for indicating whether the target object is the target object.
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 the access right, which includes the width or the height of the target object correspondingly.
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.
For example, in an embodiment, taking the target object as a robot as an example, the access 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 an end portion of the robot, and if it is determined that the target object is the robot, the size characteristic of the robot may be extracted as the preset size data.
The embodiment of the application can determine the width or the height of the target object by collecting the distance between the passing target object and the preset position point in the entrance guard, and judge whether the passing target object is the target object in the entrance guard as the size characteristic of the target object, so that the illegal target can be accurately monitored to be parallel to the robot or enter the entrance guard along with the robot, the monitoring accuracy is improved, the automation can be realized, and the manual monitoring cost is reduced.
Fig. 8 is a schematic flow chart of a second monitoring method according to an embodiment of the present application, and as shown in fig. 8, if a first location point is disposed on the left side of the door access and a second location point is disposed on the right side of the door access, the monitoring method may include the following steps:
s801, responding to a door opening request initiated by the target object, and controlling the door access to be opened.
S802, a first distance between a passing target object in the entrance guard and a first position point and a second distance between the target object and a second position point are obtained.
And S803, obtaining distance data according to the first distance and the second distance.
S804, according to the distance data, determining the size characteristics of the passing target object in the entrance guard.
And S805, obtaining a monitoring result according to the size characteristic of the target object and preset size data.
The monitoring result is used for indicating whether the target object is the target object.
Specifically, the target object passing through the entrance guard may be a target object, an illegal person who illegally intrudes, or an integral body composed of the target object and the illegal person, and the target object and the illegal person are arranged in parallel at the same time to pass through the entrance guard.
In this embodiment, the first distance is used to indicate a linear distance from the object to a first position point on the left side of the access control, and the second distance is used to indicate a linear distance from the object to a second position point on the right side of the access control. The distance data refers to two sets of values of the first distance and the second distance.
In this embodiment, the size characteristic refers to a 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.
Illustratively, the heights of the first location point and the second location point may be selected according to a size characteristic of the target object. For example, if the working platform of the robot is about 40-45 cm from the ground, the first position point may be set at a height of 41 cm, the second position point may be set at a height of 43 cm, the first distance measuring sensor may be set at the first position point, and the second distance measuring sensor may be set at the second position point, so that the widths of the working platform, the connecting rod, and the body may be conveniently acquired. The range sensor that is in not co-altitude simultaneously also can prevent that the optics that the range sensor of first position point sent from shining on the range sensor of second position point, prevents to produce the mistake and surveys, improves the range finding degree of accuracy.
This application embodiment sets up the position point respectively through left side and right side at entrance guard, can gather and obtain the distance between the current target object of entrance guard and left side position point and the distance of target object and right side position point to obtain the width of target object, accurate monitoring has illegal personnel to break into, avoids illegal personnel to utilize the target object, rather than passing through the entrance guard 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;
when the front end part passes through the entrance guard, acquiring a first distance between the front end part and a first position point and a second distance between the front end part and a second position point;
when the middle part passes through the entrance guard, acquiring a first distance between the middle part and a first position point and a second distance between the middle part and a second position point;
when the end portion passes through the entrance guard, a first distance between the end portion and the first position point and a second distance between the end portion and the second position point are obtained.
In this embodiment, when the target object passes through the entrance guard, according to the sequence of the passing process, the front end part is a part in the first passing sequence when the entrance guard passes through, i.e., a part passing through first, the middle part is a part in the second passing sequence when the entrance guard passes through, i.e., a part passing through the front end part, and finally the end part passes through the entrance guard, and the end part is a part in the third passing sequence when the entrance guard passes through. The first passing sequence, the second passing sequence and the third passing sequence are adjacent in sequence.
