Description

Control system that regulates the data transmission cycle {CONTROL SYSTEM REGULATING DATA TRANSMISSION CYCLE}

Various embodiments of this document relate to a control system that adjusts the data transmission cycle.

Work sites where people work, such as construction sites or industrial sites, require safety management. The control system is required to monitor the environmental conditions at the work site and the status of people working in real time and establish a system to respond quickly in the event of an emergency situation. For this purpose, the worker may carry sensors to detect the state of the working environment.

If an accident occurs at a work site, it is necessary to determine the location and condition of the person at the site. For example, when a burial accident occurs, determination of the burial point of the buried person and whether the buried person survived are required. Through this, the control system can minimize casualties and prevent additional damage.

At the site where a user carrying a sensor is working, the site conditions and the user's biometric information can be monitored through the sensor. However, if the work site is an area where wireless communication is poor, it may be difficult to transmit and receive signals through the detector. In particular, in the case of underground construction sites, even if an emergency condition is detected through a detector, it may be difficult to prevent an accident because the transmission and reception of signals from the detector to the terminal is not smooth.

If an accident occurs at a work site, the detector may be discharged in a short period of time as it operates continuously. If the sensor is discharged, rescue operations may be difficult because information about the user's condition or the condition of the scene cannot be obtained.

Figure 4 shows an example of the operation of the control system, according to one embodiment.

Referring to FIG. 4 , in operation 401, the detector 100 may be configured to obtain data related to the user 20 and data related to the surrounding environment of the work site. The sensor 100, when carried by a user (e.g., user 20 in FIG. 1), provides information about the location of the user 20, information about the biometric information of the user 20, and/or tasks. Information about the environment of the site (e.g., atmospheric information at the work site) can be obtained, and the obtained information can be converted into data.

In operation 402, the detector 100 may transmit the acquired data to the access point 200. The communication module of the detector 100 (e.g., the communication module 110 of FIG. 3) transmits data to the communication module of the access point 200 (e.g., the communication module 210 of FIG. 3) through the local area network 30. ) can be sent to.

In operation 403, the access point 200 may transmit data received from the detector 100 to the terminal 300. The access point 200 may transmit data to the terminal 300 through the network 30 or to another access point 200' connected to the terminal 300. The terminal 300 may receive data related to the user 20 and data related to the surrounding environment from the access point 200.

In operation 404, the terminal 300 may monitor the status of the work site and/or the status of the user 20 through the received data. The terminal 300 can provide information about the work site to the manager at the work site, and the manager can monitor the situation at the work site in real time through the terminal 300.

At operation 405 , access point 200 may be configured to identify the state of user 20 based on data received from sensor 100 . The access point 200 may identify whether the state of the user 20 is the first state or the second state, based on data received from the detector 100.

At operation 406, the access point 200 may identify whether the state of the user 20 is the second state. . For example, the access point 200 compares data related to the user 20 and/or data related to the surrounding environment of the work site with a threshold for determining the second state, which is an emergency state, to determine the state of the user 20. It is possible to identify whether is in the second state. If the state of the user 20 is not the second state, that is, if the state of the user 20 is the first state, the access point 200 detects the user based on the data received from the detector 100. The state of (20) can be identified (e.g., operation 405).

In operation 407, the access point 200 may be configured to adjust the data transmission period when the state of the user 20 is the second state. The access point 200 may adjust the period of transmitting data to the terminal 300 over time. For example, immediately after identifying the second state, data may be transmitted to the terminal 300 based on a first period for a first time, and after the first time has elapsed, during a second time, data may be transmitted to the terminal 300. Data may be transmitted to the terminal 300 based on a second period that is longer than the period. The access point 200 adjusts the data transmission cycle over time, thereby controlling the battery module of the detector 100 (e.g., the battery module 130 in FIG. 3) and the battery module of the access point 200. (For example, the battery module 240 in FIG. 3) can be used efficiently. The operations of the access point 200 described above may be performed by the monitoring module 220 (eg, the monitoring module 220 of FIG. 3).

In operation 408, the access point 200 may transmit a signal including information about the second state of the user 20 to the terminal 300. In other words, the access point 200 may notify the terminal 300 that the user 20 is in an emergency situation. Additionally, the access point 200 may notify the user 20 located at the work site of the second status through the notification module 230 (eg, the notification module 230 in FIG. 3). For example, the access point 200 transmits a sound signal indicating the second state through the notification module 230, thereby making the users 20 at the work site aware of the emergency situation.

In operation 409, the terminal 300 may perform a designated emergency operation in response to receiving a signal containing information about the second state from the access point 200. For example, the terminal 300 may notify the manager of an emergency situation. For another example, the terminal 300 can notify the fire department. As another example, the terminal 300 may report an emergency situation to a government office (eg, fire department).

Figure 5 shows an example of the operation of an access point of a control system, according to an embodiment.

Referring to FIG. 5 , in operation 501, an access point (eg, access point 200 of FIG. 1) may receive data from a detector (eg, detector 100 of FIG. 1). Operation 501 may correspond to operation 401 of FIG. 4 . For example, the motion detection sensor of the detector 100 (e.g., the motion detection sensor 127 in FIG. 3) can identify the motion of a user (e.g., the user 20 in FIG. 1), and the user 20 ) can be provided to the access point 200.

At operation 502, the access point 200 may identify whether the movement of the user 20 is below a threshold. The access point 200 may compare the movement of the user 20 with a threshold based on the data received from the detector 100 and identify that the movement of the user 20 is less than the threshold. The threshold may be determined in advance based on the movement of the user 20, which can generally be identified while the user 20 is performing work at a work site or taking a break.

At operation 503, access point 200 may identify that user 20 has transitioned from the first specified state to a second state in response to identifying that movement of user 20 is below a threshold. In other words, the access point 200 may identify that an emergency situation has occurred in the user 20 in response to identifying that the movement of the user 20 is below the threshold.

In operation 504, the access point 200 may transmit data received from the detector 100 to a terminal (eg, terminal 300 in FIG. 1) based on a first period during a first time. For example, for 10 minutes after identifying the second state, the access point 200 provides information about the location of the user 20, biometric information of the user 20, and the environment of the work site to the terminal 300. Data containing information about can be continuously transmitted. The access point 200 transmits data to the terminal 300 based on a first period for a first time at the beginning of an emergency situation, and the terminal 300 receives data from the access point 200. Through this, it is possible to quickly recognize an emergency situation and quickly obtain information about the user 20 and the work site.

In operation 505, the access point 200 may identify whether the state of the user 20 has switched from the second state to the first state after the first time period has elapsed. For example, through data received from the detector 100, when the access point 200 identifies movement of the user 20 that exceeds a threshold, the state of the user 20 is switched to the first state. can be identified.

At operation 506, in response to identifying that the state of the user 20 has not transitioned to the first state and is remaining in the second state, the access point 200 determines the period for transmitting data to be less than the first period. It can be adjusted to a long second cycle. The access point 200 may adjust the data transmission period based on the passage of time. For example, the access point 200 transitions to the second state and, after 10 minutes, in response to identifying that it remains in the second state, sends data to the terminal 300 every 30 seconds for 1 hour. It may be configured to transmit to. After 1 hour has passed, the access point 200 may be configured to transmit data to the terminal 300 every minute for 24 hours. After 24 hours have elapsed, the access point 200 may be configured to transmit data to the terminal 300 every 10 minutes. Regardless of the period, when the access point 200 captures the movement of the user 20 from the detector 100, the access point 200 may transmit data regarding the movement of the user 20 to the terminal 300. The above-mentioned time and period are only illustrative and are not limited thereto.

According to one embodiment, the control system 10 identifies the second state and then adjusts the data transmission cycle to control the battery module of the detector 100 (e.g., the battery module 130 in FIG. 3) and The battery module of the access point 200 (e.g., the battery module 240 in FIG. 3) can be efficiently managed. For example, in a situation where the work site is buried, the detector 100 and the access point 200 are discharged when the battery module 130 of the detector 100 and the battery module 240 of the access point 200 are discharged. Up to this point, data transmission and reception operations can be continuously performed. In the case of the comparative example, since information about the user 20 and the work site cannot be obtained after discharge, rescue activities for the user 20 may become difficult. On the other hand, the control system 10 according to one embodiment may provide information for rescue activities of the user 20 by adjusting the cycle of transmitting and receiving data and slowing down the discharge time.

Figure 6 shows another example of the operation of an access point of a control system, according to an embodiment.

Referring to FIG. 6, in operation 601, an access point (e.g., access point 200 in FIG. 1) obtains the concentration of a substance contained in the atmosphere from a detector (e.g., detector 100 in FIG. 1). You can. The access point 200 may obtain the concentration of a specified substance contained in the atmosphere of the work site from data related to the surrounding environment of the work site obtained from the detector 100. Designated substances may be, for example, but are not limited to hazardous gases such as carbon monoxide, hydrogen sulfide, and methane.

At operation 602, the access point 200 may identify whether the concentration of the specified substance exceeds a threshold. The threshold can be set at a concentration that allows entry of a specified substance into the body through respiration. The threshold may be set differently for each type of designated material. For example, the threshold for carbon monoxide may be set to 30 ppm and the threshold for hydrogen sulfide may be set to 10 ppm, but are not limited thereto.

At operation 603, in response to identifying that the concentration of the specified substance exceeds the threshold, the access point 200 sends the sensor 100 data embedded with biometric information of the user (e.g., user 20 of FIG. 1). You can request transmission of . In response to receiving the request from the access point 200, the detector 100 may transmit data embedding biometric information of the user 20 to the access point 200. The access point 200 can identify the state of the user 20 through data in which biometric information is embedded. For example, the access point 200 may identify whether the breathing of the user 20 is normal, the movement of the user 20 is normal, and/or whether the user 20 is dead.

In operation 604, the access point 200 may transmit data received from the detector 100 to a terminal (eg, terminal 300 in FIG. 1). The terminal 300 can receive the data from the access point 200 and monitor the environmental status of the work site. The access point 200 may transmit the status of the identified user 20 to the terminal 300, and the terminal 300 may be configured to perform follow-up actions based on the status of the user 20. . For example, if the user 20's breathing is not normal, the terminal 300 may notify the administrator of the user 20's condition and transmit an emergency signal. For another example, when the user 20 is dead, the administrator may be requested to evacuate other users 20 from the user 20's location.

According to one embodiment, the control system 10 can analyze the concentration of substances contained in the air at a work site in real time and identify whether the environment is one in which the user 20 can work. According to one embodiment, when the concentration of harmful gas exceeds the threshold, the control system 10 may identify the state of the user 20 through data in which the user's 20 biometric information is embedded. In addition, even if the user 20 does not recognize that the concentration of harmful gas exceeds the threshold, it is possible to identify whether the concentration of harmful gas exceeds the threshold through the control system 10. According to one embodiment, the control system 10 can prevent accidents caused by harmful gases by monitoring the work environment.

Figure 7 shows an example of a work site to which a control system is applied, according to an embodiment.

According to one embodiment, UAV 400 may be operatively coupled to access point 200. The access point 200 may transmit a signal for controlling the operation of the UAV 400 to the UAV 400. For example, the access point 200 may transmit a signal to the UAV 400 requesting that the UAV 400 move to a specific location, and the UAV 400 may access the signal in response to receiving the signal. You can move to the location designated by point 200. UAV 400 may be configured to transmit a signal to the access point 200. For example, the UAV 400 may include a camera capable of capturing images, and may transmit image signals captured through the camera to the access point 200.

According to one embodiment, the access point 200 may transmit a signal requesting the UAV 400 to move to the location received from the detector 100. If an accident occurs at a work site, it may be difficult for people to enter the accident site. For example, if a burial accident occurs at an underground work site, it may be difficult for people to enter the work site, making it difficult to determine the site situation. According to one embodiment, the access point 200 may move the UAV 400 to the location based on information about the location of the user 20 received from the detector 100.
