The invention relates to the technical field of coal mine dust removal, in particular to a coal mine mining dust prevention system and its application method. The exhaust mechanism designed in the present invention is provided with an exhaust fan and a spare exhaust fan. When the dust concentration increases, the standby exhaust fan can be turned on to enhance the dust removal effect. The designed dust removal mechanism adopts the cylindrical surface of the first dust removal cover and the second dust removal cover as the dust removal surface, which increases the dust removal area and obtains better dust removal effect. At the same time, when the standby exhaust fan is turned on for dust removal, it can also ensure good dust removal effect. The designed elastic water pipe and the support pipe are slidingly connected, and the water curtain door can be moved without dismantling the water curtain door. The designed monitoring mechanism can monitor the dust concentration in real time. When the dust concentration is too high, it can send a signal to the control center to turn on the backup exhaust fan to enhance the dust removal effect. The monitoring mechanism is designed with a telescopic cylinder and a cleaning block, which can realize regular automatic cleaning of the lens and ensure the monitoring effect of the monitoring mechanism is accurate.

The invention discloses a soft package battery module and a manufacturing method thereof. In one embodiment of the invention, the soft package battery module comprises a soft package battery module body which comprises a soft package battery pack, a battery protection plate and a battery pack top plate; an optical fiber demodulator which is fixed on the battery pack top plate; and an optical fibergas sensor which is fixed at a position, close to the tab of the soft package battery in the soft package battery pack, on the battery protection plate and is connected with the optical fiber demodulator through the optical fiber of the optical fiber gas sensor. Real-time gas monitoring can be carried out on the independent soft package battery module, the signal interference resistance is high,the durability is good, the soft package battery module can be used in severe environments of high temperature, high voltage and the like, a sensitive and accurate monitoring effect is achieved, and safety accidents caused by toxic and harmful gas leakage of the soft package battery module can be greatly reduced.

The application discloses a method, device, equipment and storage medium for monitoring the amount of information sent, which relate to the technical field of information processing, and specifically to the technical field of big data. The method for monitoring information transmission volume includes: determining a first number set, a plurality of telephone numbers in the first number set are target telephone numbers for information transmission; determining a second number set, and the second number set is used for monitoring information transmission As a result, the second number set includes valid phone numbers and empty numbers; based on the phone numbers in the first number set, determine one or more phone numbers in the second number set as the first number Set the corresponding monitoring number.

An intelligent fire extinguishing device for an underground roadway, including a monitoring system, an alarm system, a fire extinguishing system and a control system. The system and the alarm system are connected separately, and the monitoring system is used to monitor the temperature change of the coal wall of the underground roadway in real time and judge whether there is spontaneous combustion. The present invention adopts the combination of temperature measuring method and gas analysis method to comprehensively judge whether spontaneous combustion occurs to improve the accuracy, and the azimuth memory function can also accurately judge the area where it occurs, and integrates monitoring and fire extinguishing to realize accurate fire extinguishing in a short time, which is more reflected The intelligence of the device. The invention integrates the monitoring and prevention of coal spontaneous combustion, realizes accurate, rapid and intelligent fire extinguishing from multiple aspects, thereby reducing economic losses and ensuring the safety of underground workers.

The invention discloses a built-in LTPS display panel pixel point monitoring system, which includes a display panel. The display panel includes a panel substrate, a liquid crystal layer, and a polarizing layer from the inside to the outside, and m×n pixels are etched on the panel substrate. A pixel point array of points, the panel substrate is also provided with a detection and acquisition module, the detection and acquisition module includes a pixel monitoring array and a timing sampling circuit, the pixel monitoring array includes m×n monitoring units, and the monitoring unit and The pixels are in one-to-one correspondence. Beneficial effects: Microscopically detect whether each possible bad pixel is normal, the monitoring effect must be direct and accurate, the monitoring signal of the monitoring unit is compiled and converted into a timing signal flow by the timing sampling circuit, and the self-checking analysis module analyzes Timing information flow, get the pixel dead point result, you can quickly know the location of the bad point.

The invention discloses a bluetooth earphone, the bluetooth earphone can be accommodated in a charging compartment, and is provided with a pogo pin adapted to the charging compartment; the bluetooth earphone includes: a voltage detection unit for detecting the pogo pin The first voltage of the first voltage; the voltage pulling unit is used to determine that when the first voltage is not greater than the first preset voltage value, the pogo pin is pulled up; the voltage detection unit is also used to detect the pogo pin and a state output unit, configured to compare the second voltage with the first voltage, to compare the first voltage with a first preset voltage value, or to compare the second voltage and the second preset voltage value, and output the status of the earphones according to the comparison results. The structure is simple, and the status of the earphones in and out of the warehouse can be monitored efficiently. The invention also discloses a bluetooth earphone state monitoring method and a readable storage medium.
