The service platform 300 can be used to receive and display the data (particulate matter concentration information and harmful gas concentration information) transmitted by the detection device 100. The service platform 300 can be a computing device such as a server, a notebook or a smart phone. The service platform 300 and the detection device 100 can be connected by wire or wirelessly.

[0036] In the detection device 100 , the data processing device 130 is respectively connected to the particle sensor 110 , the gas sensor 120 and the communication device 140 for communication, and the communication device 140 is respectively connected to the particle sensor 110 and the gas sensor 120 for communication.

[0038] The target environment is the environment where the detection device is located. The particle sensor 110 may be, for example, a PM1.0 sensor, a PM2.5 sensor, or a PM10 sensor.

[0039] In one embodiment, the particle sensor 110 can collect the particle fog information in the target environment in real time.

[0040] The gas sensor 120 is used to collect information on the concentration of harmful gases in the target environment.

[0041] The harmful gas may be a gas that is harmful to the health of the operator. The harmful gas may include, for example, at least one of the following: volatile organic gas, carbon monoxide, carbon dioxide, formaldehyde, and methane. The gas sensor may be, for example, a VOC sensor, a carbon dioxide sensor, and a carbon monoxide sensor.

[0042] In one embodiment, the gas sensor 120 can collect harmful gas concentration information in the target environment in real time. The gas sensor 120 and the data processing device 130 can use RS485 communication mode for data transmission, and the data processing device 130 can poll the gas sensor 120 to obtain harmful gas concentration information.

[0046] In one embodiment, a preset particle concentration threshold and a preset gas concentration threshold may be preset, and when the harmful gas concentration information exceeds the preset gas concentration threshold, and / or the particle concentration information exceeds the preset particle concentration threshold, the target environment is determined to be abnormal.

At the same time, in the embodiment of the present disclosure, the communication device sends the particle concentration information and the harmful gas concentration information to the service platform when receiving the data acquisition instruction sent by the service platform, thereby eliminating the need to send data to the service platform in real time, saving the power consumption of the detection equipment and improving the endurance of the detection equipment. In addition, in the embodiment of the present disclosure, the particle sensor and the gas sensor are used to transmit the corresponding particle concentration information and the harmful gas concentration information to the service platform, and the corresponding detection record is generated on the service platform, thereby achieving efficient and convenient acquisition of real-time data of substances (harmful gases and particles) that endanger the operators in the target environment, and providing reliable data support for finding key control points of hazards in the target environment, formulating risk control guidelines and policies, and risk analysis and trend analysis.

When the difference between the maximum and minimum values ​​is within the preset difference threshold, it is determined that the detection device 100 has not moved for more than the preset time period. When the difference between the maximum and minimum values ​​exceeds the preset difference threshold, it is determined that the detection device 100 is in a moving state within the preset time period.

[0096] The search area can be determined with the location information of the service platform 100 as the center and the preset search radius information as the radius. The service platform 300 can be communicatively connected to multiple detection devices and can determine other detection devices in the search area except the detection device 100 as target detection devices.

[0097] The way in which the service platform 300 determines whether the target environment is abnormal is the same as the way in which the detection device 100 determines whether the target environment is abnormal, and will not be repeated here.

[0098] The service platform 300 is also connected to multiple preset cameras for communication, receiving and storing videos shot by multiple preset cameras, and the service platform 300 also stores the location information of the multiple preset cameras. A preset camera that differs from the location information of the detection device 100 by a preset distance can be determined as a target camera. The video collected by the target camera can be analyzed manually or by CNN (Convolutional Neural Network) to determine whether the target object wearing the detection device 100 falls, wherein the target object can be, for example, an operator working in the target environment.

[0099] In one embodiment, the service platform 300 does not process when it determines that the detection device 100 is in a moving state for a preset period of time; or, when it determines that the detection device has not moved for more than a preset period of time, the target environment is normal, and it is determined that the target object wearing the detection device 100 has not fallen, no process is performed.

[0100] In the embodiments of the present disclosure, the position information of the detection device is used to determine whether the target object has moved within a preset time period, and when it has not moved, it is determined whether the target environment is abnormal and whether the target object has fallen down. When the target object has not moved for more than a preset time period and the target environment is abnormal, or when the target object has not moved for more than a preset time period and the target object is in a fallen state, that is, the target object is in a dangerous state, a search area is determined based on the position information of the detection device and the preset search radius information, and a distress message is sent to the target detection device in the search area, thereby realizing timely detection of whether the target object is in a dangerous state, and when it is determined that the target object is in a dangerous state, a distress message is sent to the nearby (search area) target detection device.
