Description

Technical Field

[0001] The invention belongs to the field of coal mine protective equipment, and relates to a method and a system for reducing the power consumption of coal mine occupational hazard factor monitoring and dust protection wearable equipment. Background Art

[0002] Coal miners are exposed to occupational hazards such as noise, heat damage, and dust for a long time during work. Dust in particular poses a great threat to workers' health and can cause serious occupational diseases such as pneumoconiosis. In order to establish the last line of defense for workers against occupational hazards in coal mines, researchers have developed a variety of personal protective equipment. In recent years, in particular, occupational hazard factor monitoring and dust protection wearable equipment with integrated multiple monitoring functions have been developed. These devices can monitor environmental noise, temperature and humidity, dust and other occupational hazard factors in coal mines in real time, and provide dust breathing protection for workers through wearable equipment, thereby more effectively protecting the health of miners. Coal mining operations usually have an 8-hour shift as the work cycle, so wearable equipment needs to be used continuously for more than 8 hours to meet the miners' needs.

[0003] Increasing the battery capacity will increase the size, weight and safety of wearable devices, which does not meet the safety technical requirements for light and comfortable wearable devices and coal mine equipment. Therefore, the low power consumption management method of wearable equipment is particularly important for miners working for long periods of time underground in coal mines, because it means that the equipment can continue to operate without frequent charging, thereby ensuring the continuity of monitoring and protection, while significantly improving the energy efficiency of the equipment and reducing energy consumption.

[0004] Traditional coal mine occupational hazard monitoring and dust protection wearable equipment power consumption management strategies are usually:

[0005] Method 1: The wearable device is started and stopped by the main power switch. After startup, the occupational hazard factor monitoring unit, air supply fan, human-computer interaction terminal, data transmission module and other units in the device are all in full-time working state. This method consumes a lot of power.

[0006] Method 2: Based on Method 1, add the interactive terminal screen off function to wake up the screen display when you need to view it, which can reduce the power consumption of the interactive terminal display. Summary of the invention

[0007] In view of this, the purpose of the present invention is to provide a method and system for reducing the power consumption of coal mine occupational hazard monitoring and dust protection wearable equipment. Under the premise that it is impossible to further increase the battery capacity of coal mine occupational hazard monitoring and dust protection wearable equipment, while ensuring the normal operation of the wearable equipment, reducing the power consumption of the equipment, extending the battery life and use time of the equipment are technical problems that need to be solved in this solution.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0067] See also Figures 1 to 8 The system includes a coal mine occupational hazard monitoring and dust protection wearable equipment host and a monitoring and maintenance center.

[0068] (1) The main unit of the coal mine occupational hazard factor monitoring and dust protection wearable device includes an interaction unit, a storage unit, a location module, a dust protection unit, an environmental occupational hazard factor measurement unit, an identity authentication module, and a communication module.

[0069] ① The interactive unit includes buttons, display screen, and sound and light alarm module. The buttons can be used to turn the machine on and off, view measurement data, and adjust the air volume.

[0070] ②The storage unit is used to store occupational hazard data measurement data, identity authentication information data, location information data, air volume system setting data, etc.

[0071] ③The location module is used to obtain the location of the wearable device user.

[0072] ④The dust protection unit includes a dust filtration unit, an active air supply unit, a protective mask and connecting air circuits.

[0073] ⑤The environmental occupational hazard factor measurement unit is used to measure data such as environmental noise, temperature and humidity, dust concentration, and toxic and harmful gas concentration.

[0074] ⑥The identity authentication module is used to verify the user's identity, such as swiping a card, fingerprint and other biometric information, entering a password, etc.

[0075] ⑦The communication module is used to transmit the data in the storage unit to the monitoring and maintenance center.

[0076] (2) The monitoring and maintenance center includes a charging unit, a communication module, and a data management platform.

[0077] ①The charging stand is used to charge wearable devices.

[0078] ②The communication module is used to receive data transmitted by the wearable device host.

[0079] ③The data management platform is used to store and manage wearable equipment data for subsequent analysis and application.

[0080] The usage steps include: 1. user identity authentication, 2. personnel location confirmation, 3. wearable control terminal interaction and data measurement, 4. data transmission and storage.

[0081] Step 1: Press the power button of the wearable device to turn on the power supply, start the identity authentication unit, and other modules do not work. The wearable device host screen prompts the user to perform identity authentication.

[0082] The identity authentication process is as follows: First, the authentication times are initialized to 0, and the authentication unit captures the authentication action of the operator. If there is no authentication action within s seconds, the shutdown operation is executed; if there is an authentication action within s seconds, the authentication information is confirmed. At the same time, the authentication times are increased by 1, and the system determines whether the authentication times exceed the set allowable threshold n. If the authentication times exceed n, the control terminal screen prompts "Authentication times exceeded", delays for 5 seconds, and the wearable equipment system shuts down; if the authentication times do not exceed n, the system confirms whether the authentication information is correct. When the authentication information is correct, the positioning function is turned on; when the authentication fails, wait for the next authentication.

[0083] Step 2: Confirm personnel location

[0084] When the user's identity is successfully confirmed, the wearable device confirms the user's location information.

[0085] The specific steps are as follows: After turning on positioning, turn off the identity authentication unit to reduce the power consumption of the identity authentication unit. Get the current location information and determine the location. If it is not in the operating area, update the location every 10 seconds and continue to determine the location; if it is in the operating area, change the positioning update time to 60 seconds per cycle and turn on the timing function.

[0086] Step 3: Wearable control terminal interaction and data measurement

[0087] After the wearable control terminal is turned on, the system begins to measure occupational hazard factors, safety and physiological health information of operators; at the same time, the system settings and air supply volume adjustment can be performed by pressing buttons.

[0088] According to the real-time demand characteristics of the measurement data, the data is classified and measured.

[0089] ① The sampling interval for data with low real-time requirements such as environmental noise, ambient temperature and humidity, and dust concentration is long, and the data is acquired once every minute;

[0090] ② The real-time requirements for air supply fan flow, toxic gas concentration, etc. are high, and the sampling interval is short, set to obtain data once every 10 seconds.

[0091] After data collection, it is compared with the set value. If there is no abnormality, the data is stored and updated. If there is an abnormality, the data is stored and updated and an alarm is processed in time. In order to reduce the power supply load caused by data transmission, the wearable equipment does not transmit data during data measurement and dust protection.

[0092] The system determines whether a key is pressed on the control terminal. If so, the screen is awakened. If no key is pressed, the screen goes into sleep mode. The screen stays on for 10 seconds after being awakened. If other key operations are performed within 10 seconds, the screen remains on and the system executes the corresponding key commands. If no key operation is performed within 10 seconds after the screen is awakened, the screen goes into sleep mode.

[0093] Step 4: Data transmission and storage

[0094] When the wearable device is used up, it is charged and maintained. A data transmission module is integrated in the charging unit. When it is detected that the power of the wearable device is ≥20%, data transmission is performed, and the data stored in the wearable device is synchronized to the data management platform for storage.

[0095] 1. Only after identity authentication and positioning confirmation can the occupational hazard factor monitoring and dust protection functions of the wearable device be used, reducing the energy consumption of the equipment caused by non-bound users in non-working areas;

[0096] 2. According to the real-time characteristics of the measured data, the data such as environmental noise, temperature and humidity, dust concentration, and toxic gas concentrated air supply fan flow are collected, stored and updated by category, thus avoiding the energy consumption of equipment caused by continuous monitoring of all parameters;

[0097] 3. Only data is measured, stored and updated in the working area. The data is stored locally on the wearable device and synchronized to the data management platform during charging, which improves the battery life of the equipment when used underground.
