[0007] Furthermore, when the environmental gas safety detection result is an environmental gas safety anomaly, the control of the mobile robot to perform corresponding environmental gas safety feedback work based on the output environmental gas safety detection result also includes: if the mobile robot does not receive feedback from the user terminal granting an environmental gas safety anomaly unlocking command in the first time, the control of the mobile robot to transmit the environmental gas safety detection result and preset emergency information to the network emergency rescue platform.

[0008] Furthermore, the process of controlling the mobile robot to perform user harm detection, in order to detect whether the user is affected by harmful gases, specifically includes: controlling the mobile robot to traverse each room and search for and identify the user in each room; if the mobile robot does not find and identify the user in the current room, then controlling the mobile robot to enter the next room; if the mobile robot finds and identifies the user in the current room, then controlling the mobile robot to acquire the user's vital signs, and determining whether the user's health is affected by harmful gases based on the user's vital signs.

Attached Figure Description

[0014] Figure 1 This is a flowchart illustrating a mobile robot control method based on environmental gas safety according to one embodiment of this application. Detailed Implementation

[0015] The embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described below are for illustrative purposes only and are not intended to limit the scope of this application.

[0016] This application provides a mobile robot control method based on environmental gas safety in one embodiment. The method aims to achieve intelligent detection of environmental gas safety and execute corresponding environmental gas safety feedback based on the detection results. This improves the intelligence level of home environmental gas safety detection and feedback, and increases the user's success rate in self-rescue during abnormal environmental gas safety situations. Specifically, as... Figure 1 As shown, the mobile robot control method based on environmental gas safety includes: Control the mobile robot to rotate around its own position to acquire ambient gas; utilize the mobile robot's mobility to acquire ambient gas by rotating, thus acquiring ambient gas while the gas is flowing.

[0017] The mobile robot uses a gas analysis device mounted on its body to analyze the gas composition of the ambient gas and determines whether harmful gases are present. Specifically, this step analyzes the gas components contained in the ambient gas to identify whether harmful gases are present. The method for determining whether harmful gases are present can be, but is not limited to, comparing each gas component in the ambient gas analyzed by the gas analysis device with a pre-stored list of harmful gases to determine whether each gas component in the ambient gas is a harmful gas.

[0018] If harmful gases are present in the ambient air, the concentration of various harmful gases in the ambient air is analyzed by the gas analysis device mounted on the mobile robot. Based on the analyzed concentration of various harmful gases in the ambient air, it is determined whether the concentration of any harmful gas reaches its corresponding preset concentration. Since different types of harmful gases require different concentrations to cause damage to human health, different types of harmful gases have corresponding preset concentrations, thereby enabling more accurate identification of whether harmful gases in the ambient air will affect human health.

[0019] When the concentration of a harmful gas reaches its corresponding preset harmful gas concentration, the mobile robot is controlled to output an environmental gas safety detection result indicating an abnormal environmental gas safety. When there is no harmful gas in the environment, or when the concentrations of all kinds of harmful gases present in the environment do not reach their corresponding preset harmful gas concentrations, the mobile robot is controlled to output an environmental gas safety detection result indicating no abnormal environmental gas safety. Due to the complexity of environmental gases, a small amount of harmful gases are usually mixed in with the environment. When the concentration of harmful gases does not reach the corresponding preset harmful gas concentration, this embodiment configures the environmental gas safety detection result as indicating no abnormal environmental gas safety to reduce users' anxiety about environmental gas safety.

[0020] The mobile robot is controlled to perform corresponding environmental gas safety feedback based on the environmental gas safety detection results. Specifically, the environmental gas safety feedback can be, but is not limited to, the mobile robot providing feedback on the environmental gas safety detection results to residents, indicating whether the gas safety in the current environment is abnormal, so that residents can promptly grasp the environmental gas safety situation and take self-rescue measures when the environmental gas safety is abnormal. It can also be that the mobile robot provides feedback on environmental gas safety optimization, etc. This embodiment controls the mobile robot to analyze the types of gases in the environmental gas to determine the presence of harmful gases, and then performs targeted detection on the concentration of harmful gases in the environmental gas, comparing the concentration of various harmful gases with their corresponding preset harmful gas concentrations. Only when the concentration of any harmful gas reaches the corresponding preset harmful gas concentration, that is, when at least one harmful gas concentration will cause harm to the health of residents, is the environmental gas safety detection result configured as abnormal, so that residents can protect their health or take self-rescue measures based on the environmental gas safety detection results. The mobile robot is controlled to perform different environmental gas safety feedback tasks for different environmental gas safety detection results, improving the intelligence level of home environmental gas safety detection and feedback.

[0021] As one implementation method, the mobile robot control method based on environmental gas safety further includes, before controlling the mobile robot to rotate around its own position to acquire environmental gas: controlling the mobile robot to acquire pet barking sounds and determining whether the pet barking sounds meet preset abnormal pet barking conditions; if the pet barking sounds meet the preset abnormal pet barking conditions, then controlling the mobile robot to rotate around its own position to acquire environmental gas. Since pets typically have a more sensitive sense of smell than humans, they usually react faster when abnormal gases in the environment affect safety. Therefore, in this implementation, pet barking sounds are used as the trigger condition for the mobile robot to acquire and analyze environmental gases, thus eliminating the need for the mobile robot to perform environmental gas detection for extended periods, improving the utilization of computing resources, maintaining detection accuracy while reducing detection costs.

[0022] As one implementation method, the controlled mobile robot performs corresponding environmental gas safety feedback based on the output environmental gas safety detection results, specifically including: When the ambient gas safety detection result indicates an abnormal ambient gas safety, the mobile robot is controlled to traverse each room and play the corresponding voice alarm. Simultaneously, the mobile robot transmits the ambient gas safety detection result to the user terminal. This step, by controlling the mobile robot to traverse each room and play the voice alarm when an ambient gas safety abnormality occurs, ensures that even if the resident does not carry a user terminal, the resident has the opportunity to receive the corresponding voice alarm from anywhere in the home, increasing the resident's success rate in receiving the alarm in the event of an ambient gas safety abnormality, thereby improving the resident's self-rescue success rate in such situations.

[0023] When the environmental gas safety test result indicates that there are no abnormalities, the mobile robot is controlled to traverse each room, acquiring and analyzing environmental gases upon arrival to update the environmental gas safety test results. This step, when environmental gas safety is normal, involves controlling the mobile robot to traverse each room, selectively acquiring and analyzing environmental gases in different rooms to prevent situations where harmful gases in some rooms are not fully detected due to poor air circulation, thus optimizing the accuracy of environmental gas safety testing.

[0024] In one implementation, when the environmental gas safety detection result indicates an environmental gas safety anomaly, the control of the mobile robot to perform corresponding environmental gas safety feedback based on the output environmental gas safety detection result further includes: controlling the mobile robot to request an environmental gas safety anomaly unlocking command from the user terminal; after the mobile robot requests the environmental gas safety anomaly unlocking command from the user terminal, controlling the mobile robot to start a timer and determine whether feedback from the user terminal granting the environmental gas safety anomaly unlocking command is received; if the mobile robot receives feedback from the user terminal granting the environmental gas safety anomaly unlocking command within the first time, controlling the mobile robot to stop traversing each room and stop playing the voice alarm corresponding to the environmental gas safety anomaly; if the mobile robot does not receive feedback from the user terminal granting the environmental gas safety anomaly unlocking command within the first time, controlling the mobile robot to perform a user harm detection process to detect whether the user is affected by harmful gases. Specifically, the first time is a pre-set time length for detecting the timeliness of the user's response, which may be, but is not limited to, 3 minutes, 5 minutes, etc. Since the concentration of harmful gases in the environment can affect the health of residents, the consequences of which may include users falling into a coma, being unconscious, or being unable to respond to information, this implementation method determines whether the user is affected by harmful gases by judging whether the user responds in the first instance. This allows the mobile robot to respond in a timely manner when the user is affected by harmful gases, thereby improving the success rate of rescuing the user after being affected by harmful gases in the environment.

[0025] In one implementation, when the environmental gas safety detection result indicates an environmental gas safety anomaly, the controlled mobile robot performs corresponding environmental gas safety feedback based on the output environmental gas safety detection result. This further includes: if the mobile robot does not receive feedback from the user terminal granting an unlock command for environmental gas safety anomalies within the first instance, the controlled mobile robot transmits the environmental gas safety detection result and preset emergency information to a network emergency rescue platform. The preset emergency information includes at least the user's address and other information that facilitates the emergency rescue platform in determining the emergency location. Since some harmful gases cause extremely rapid and severe damage to user health, and excessive inhalation of harmful gases can easily cause irreversible damage, this implementation does not perform user harm detection procedures when the mobile robot does not receive feedback from the user terminal granting an unlock command for environmental gas safety anomalies within the first instance. Instead, it directly controls the mobile robot to transmit the environmental gas safety detection result and preset emergency information to the network emergency rescue platform, enabling the user to be rescued more quickly and promptly.

[0026] In one implementation, the process of controlling a mobile robot to perform user harm detection, to detect whether a user is affected by harmful gases, specifically includes: controlling the mobile robot to traverse each room and search for and identify the user in each room; if the mobile robot does not find and identify the user in the current room, it moves to the next room; if the mobile robot finds and identifies the user in the current room, it acquires the user's vital signs and determines whether the user's health is affected by the harmful gases based on these signs. The acquisition of user vital signs can be, but is not limited to, acquiring heart rate, temperature, and other vital signs detected by wearable devices worn by the user, or acquiring user posture and other vital signs through images. Since the impact of inhaling harmful gases in small amounts is difficult for users to quickly perceive, the mobile robot needs to combine user vital signs for more detailed differentiation, determining the impact of harmful gases on the user's health before the user suffers from excessive inhalation, thus more effectively instructing the user to take self-rescue measures.

[0027] As one implementation method, determining whether a user's health is affected by harmful gases based on user vital signs specifically includes: retrieving corresponding abnormal vital sign information from a preset abnormal vital sign information database according to the type of harmful gases in the ambient gas; matching the user's vital signs with the corresponding abnormal vital sign information; if the matching degree between the user's vital signs and the corresponding abnormal vital sign information reaches a preset matching threshold, it is determined that the user's health is severely affected by harmful gases; if the matching degree between the user's vital signs and the corresponding abnormal vital sign information does not reach the preset matching threshold, it is determined that the user's health is only slightly affected by harmful gases.

[0028] As one implementation method, the mobile robot control method based on environmental gas safety further includes: if the mobile robot identifies a user while traversing the room, and the user's health is severely affected by harmful gases, then the mobile robot is controlled to collect images and videos of the user, and transmits the environmental gas safety detection results, user images and videos, and preset emergency information to a network emergency rescue platform. This implementation method, by controlling the mobile robot to traverse the room, enables the mobile robot to effectively identify users whose health is affected, provide appropriate emergency assistance, and improve the success rate of rescue for users affected by harmful gases.
