Description

Technical Field

[0001] The present application relates to a monitoring system, and more particularly to a monitoring system that adjusts a detection range according to different environmental parameters. Background Art

[0002] With the improvement of labor safety and health awareness, the safety of construction sites has received more and more attention in recent years. There are many unexpected situations on construction sites, especially in some outdoor construction areas, which are more prone to accidents. Therefore, in order to improve the safety of construction sites, operators need to manage more carefully in relatively dangerous construction areas such as mountainous areas, high altitudes, river valleys, unstable geology or poor air circulation. Since the outdoor construction environment changes rapidly, such as sudden rain or sudden gusts of wind upstream, the probability of danger on the construction site may increase sharply. Traditional construction site management methods often fail to respond to environmental changes in time. In practice, it is often necessary to wait until the on-site management personnel notice that the construction site environment has deteriorated and it is not conducive to continue construction before the management personnel will notify the construction personnel to evacuate the construction site. However, if the management personnel notify too late, the construction personnel may not have time to leave the construction site and a work safety accident may occur.

[0003] Therefore, the industry needs a new monitoring system that can not only coordinate environmental changes around the construction site, but also quickly warn construction workers in dangerous locations to reduce accidents that may be caused by environmental changes. Summary of the invention

[0004] The technical problem to be solved by the present application is to provide an environmental monitoring system that can analyze the environmental parameters around a specific area and adjust the detection range of the camera according to the environmental parameters, so as to quickly determine whether there are people or objects in a dangerous position.

[0005] The present application proposes an environment monitoring system for monitoring an environment area, wherein the environment monitoring system comprises a central control device and a camera. The central control device is used to receive environmental parameters, and determine whether the environmental parameters reach a danger threshold, and generate a control signal accordingly. The camera is used to capture an environmental image associated with the environment area, and the camera is controlled by the control signal, and the control signal is used to set the camera to a first detection range or a second detection range. When the central control device determines that there is a designated person or a designated object in the first detection range or the second detection range, the central control device provides a warning signal.

[0006] In some embodiments, the environmental monitoring system may further include an environmental detector, which is disposed in the environmental area to obtain environmental parameters associated with the environmental area. When the environmental parameters do not reach the danger threshold, the control signal is used to set the camera to a first detection range, and when the environmental parameters reach the danger threshold, the control signal is used to set the camera to a second detection range. The first detection range may correspond to a first position in the environmental image, and the second detection range may correspond to a second position in the environmental image, and the second position is different from the first position. In addition, the second detection range may include site features in the environmental area. In addition, the environmental monitoring system may further include an alarm, which is disposed in the environmental area and is controlled by a warning signal to sound an alarm. Alternatively, the central control device may also send a warning signal to a mobile device, and the mobile device may be controlled by the warning signal to sound an alarm.

[0007] In some embodiments, the site characteristics in the environmental area may correspond to at least one regional attribute parameter, and the central control device receives at least the corresponding environmental parameter based on the regional attribute parameter. Here, when the regional attribute parameter indicates that the site characteristics include a high-altitude work site, the environmental parameter corresponding to the regional attribute parameter may include a wind speed parameter. When the regional attribute parameter indicates that the site characteristics include a low-lying work site, the environmental parameter corresponding to the regional attribute parameter may include a rainfall parameter or a water level parameter. When the regional attribute parameter indicates that the site characteristics include an outdoor work site, the environmental parameter corresponding to the regional attribute parameter may include a temperature parameter or a humidity parameter.

[0008] In summary, the central control device in the environmental monitoring system provided by the present application can analyze the environmental parameters around a specific area, and can dynamically control the camera according to the environmental parameters, and adjust the detection range of the camera. When the camera captures a person or object in the picture, the central control device can quickly issue an alarm to remind that there is a person or object in a dangerous position. The environmental monitoring system of the present application can quickly respond to changes in the environment and reduce accidents caused by environmental changes.

[0018] The positional relationships described in the following embodiments include: up, down, left and right. Unless otherwise specified, they are all based on the directions in which the components are drawn in the drawings.

[0019] See also Figure 1 , Figure 1 1 is a functional block diagram of an environment monitoring system according to an embodiment of the present application. As shown in the figure, the environment monitoring system 1 of this embodiment includes a central control device 10 and cameras 12a-12c. The central control device 10 can be connected to the cameras 12a-12c by wire or wirelessly, and this embodiment is not limited thereto. Figure 1 Three cameras 12a~12c are shown, but in fact the environmental monitoring system 1 does not limit the number of cameras. For example, the environmental monitoring system 1 may only include one camera 12a. In addition, the central control device 10 may also be connected to the environmental detector 14 and the alarm 16 by wire or wirelessly. However, the environmental detector 14 and the alarm 16 are not necessary components of the present application. The present application will illustrate in the embodiments that the environmental monitoring system 1 can also operate normally in the absence of the environmental detector 14 and the alarm 16. In addition, the environmental monitoring system 1 of this embodiment can be used to monitor various environmental areas. In addition to being applicable to construction sites under construction, it can also be applied to various buildings or natural terrains that are not under construction. Figure 1 For example, the cameras 12a-12c, the environment detector 14 and the alarm 16 can all be set in the environment area to be monitored, and the central control device 10 can be set in the environment area to be monitored or remotely. The following describes each component of the environment monitoring system 1 of this embodiment.

[0020] The central control device 10 is used to receive environmental parameters, and determine whether the environmental parameters have reached a dangerous threshold, and generate a control signal accordingly. In practice, the central control device 10 can be a computer or a server, and can have a networking function. The environmental parameters can come from the network, so that the central control device 10 can connect to the network to obtain the environmental parameters around the environmental area to be monitored. In this case, the environmental monitoring system 1 does not necessarily need the environmental detector 14. Of course, in the example where the environmental monitoring system 1 has an environmental detector 14, as long as the environmental detector 14 is pre-installed in the environmental area to be monitored, the central control device 10 can also directly obtain the environmental parameters from the environmental detector 14. Here, the environmental parameters can include wind speed parameters, rainfall parameters, water level parameters, temperature parameters, humidity parameters, or various measurement data or forecast data related to the natural environment, which are not listed one by one in this embodiment.

[0021] In one example, the environmental parameters obtained by the central control device 10 are associated with the environmental area to be monitored. For example, the central control device 10 can obtain specific environmental parameters in a targeted manner. In practice, the central control device 10 can mark one or more regional attribute parameters for the environmental area to be monitored, and the regional attribute parameters will correspond to the site characteristics in the environmental area. For example, assuming that there is a significant height difference on the terrain of the environmental area to be monitored, the height difference on the terrain can be a site feature. Based on the above-mentioned site characteristics, the environmental area to be monitored can be marked as a high-altitude work site, and the corresponding regional attribute parameters can be classified under the label of "high altitude". Of course, the regional attribute parameters of the high-altitude work site may also correspond to labels such as "outdoor" or "hanging", which are not limited in this embodiment. In addition, since the regional attribute parameters can be customized, this embodiment only illustrates how the regional attribute parameters can be defined, and is not used to specifically limit the content of the regional attribute parameters.

[0022] In practice, the central control device 10 can pre-set the environmental parameters corresponding to various regional attribute parameters. Taking the above example, since the environmental area to be monitored is a high-altitude work site, and because the high-altitude work site is easily affected by strong winds, the regional attribute parameter of "high altitude" can correspond to the wind speed parameter. In other words, the central control device 10 can obtain the wind speed parameter of the environmental area to be monitored from the network or the environmental detector 14 based on the regional attribute parameter of "high altitude". Those with general knowledge in the relevant technical field should understand that in this example, the environmental detector 14 can be an anemometer.

[0023] For other environmental areas to be monitored, assuming that the environmental area to be monitored is a low-lying work site, the regional attribute parameters can correspond to labels such as "low-lying", "river valley" or "outdoor". In practice, the items to be paid attention to in low-lying work sites are different from those in high-altitude work sites. Low-lying work sites may not pay special attention to wind speed, but may need to grasp the rainfall or water level around the environmental area to be monitored in real time. At this time, the central control device 10 can obtain the rainfall parameters or water level parameters around the environmental area to be monitored from the network or the environmental detector 14 based on the regional attribute parameter of "low-lying". Those with general knowledge in the relevant technical field should understand that in this example, the environmental detector 14 can be a rain gauge or a water level gauge. In addition, the label "outdoor" may be widely corresponding to all outdoor work sites, because there may be heat stroke or other heat hazards when working outdoors, so the central control device 10 may also use the regional attribute parameter "outdoor" to obtain the temperature parameters or humidity parameters around the environmental area to be monitored from the network or the environmental detector 14. Those skilled in the art should understand that, in this example, the environment detector 14 may be a thermometer or a hygrometer.

[0024] In accordance with the above, each environmental parameter should have its own danger threshold, so that after receiving the environmental parameter, the central control device 10 can compare whether the environmental parameter reaches the danger threshold. For example, assuming that the environmental area to be monitored is a high-altitude work site, after the central control device 10 obtains the wind speed parameter from the network or the environmental detector 14, it will further compare the wind speed parameter with the corresponding wind speed danger threshold. When the environmental parameter reaches the danger threshold, the central control device 10 generates a control signal to at least one of the cameras 12a~12c accordingly. Here, the cameras 12a~12c can each capture environmental images associated with the environmental area, and at least one camera 12a~12c can be controlled by the control signal, and the control signal is used to set the corresponding camera to the first detection range or the second detection range.

[0025] To explain the first detection range or second detection range of the camera, please refer to Figure 1 and Figure 2 , Figure 2 1 is a schematic diagram of an environmental image according to an embodiment of the present application. As shown in the figure, this embodiment takes a high-rise building as an example. Assuming that the camera 12a is set on the top floor of the high-rise building, the environmental image of the top floor can be as follows: Figure 2As shown. In an example, when the central control device 10 compares the environmental parameters and finds that they do not reach the danger threshold, such as when it is sunny and windless, the camera 12a can set the area around the door as the first detection range 20. In practice, the first detection range 20 can represent a dynamic detection range, that is, if a person or object appears in the area around the door, the camera 12a can detect the person or object and send a detection prompt signal to the central control device 10. Then, the central control device 10 can determine that there is a designated person or designated object in the first detection range 20 based on the detection prompt signal, thereby providing a warning signal. In other words, when the environmental parameters do not reach the danger threshold, the camera 12a can be used as a security device. When a person or object appears in the first detection range 20, the camera 12a can detect the person or object. Figure 2 When the central control device 10 is around the depicted door, it will generate a warning signal to trigger an alarm.

[0026] However, when the central control device 10 compares the environmental parameters to a dangerous threshold, such as excessive wind speed, the central control device 10 will send a control signal to the camera 12a to allow the camera 12a to set a new dynamic detection range, such as the second detection range 22. Figure 2 It can be seen that the second detection range 22 can cover the original first detection range 20, and can be used to control the entry and exit of personnel. Figure 2 In addition to the doors shown, the scope of dynamic detection is further expanded, especially to include at least site features. Since the edge of the railing of a high-rise building has a significant height difference, it can be the site feature of this environment area. Figure 2 For example, when the wind speed is high, the risk of accidental falling of people or objects in the second detection range 22 (the edge of the railing of a high-rise building) increases greatly. In other words, when the environmental parameters reach the danger threshold, the camera 12a can be used as a danger warning device to detect whether there are people or objects in a relatively unsafe position. Figure 2 When the edge of the railing is drawn, the central control device 10 will also generate a warning signal to trigger an alarm.

[0027] It is worth mentioning that the present embodiment does not limit the type of environmental images captured by the cameras 12a to 12c. For example, when the camera 12a is an ordinary surveillance camera and the environmental image captured is an image of a specific shooting angle, the first detection range or the second detection range may correspond to different areas in the picture at the same angle. However, when the camera 12a is a fisheye camera and the environmental image captured is a panoramic image, the first detection range or the second detection range may also correspond to different shooting angles, so that the first detection range or the second detection range on the picture will see different positions in the environmental area.

[0028] Back to Figure 1For example, after the central control device 10 generates a warning signal, the warning signal can be transmitted to the alarm 16, so that the alarm 16 sounds an alarm. For example, the alarm 16 can be set around the environment area to be monitored to remind people to leave unsafe locations, or remind people to remove objects in unsafe locations. In addition, in the absence of the alarm 16, the central control device 10 can also send a warning signal to a mobile device (not shown) around the environment area, and the warning signal can drive the mobile device to sound an alarm. Figure 2 For example, when the central control device 10 compares the wind speed in the environment area and finds that it has reached the danger threshold, the central control device 10 will send a warning signal to the mobile device of the person in the second detection range 22, warning the person holding the mobile device to leave as soon as possible. In addition, if the person in the second detection range 22 does not carry a mobile device, the central control device 10 may also send a warning signal to other mobile devices in the same environment area, so that other people can go to notify the people in the second detection range 22 or move the objects in the second detection range 22.

[0029] In summary, the central control device in the environmental monitoring system provided by the present application can analyze the environmental parameters around a specific area, and can dynamically control the camera according to the environmental parameters, and adjust the detection range of the camera. When the camera captures a person or object in the picture, the central control device can quickly issue an alarm to remind that there is a person or object in a dangerous position. The environmental monitoring system of the present application can quickly respond to changes in the environment and reduce accidents caused by environmental changes.
