For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] like Figure 1-2 As shown, the utility model provides a pan-tilt laser methane detector, including an electric pan-tilt platform 2, a camera 3, and a detection device 4. The camera 3 and the detection device 4 are both arranged on the electric pan-tilt platform 2, and the electric pan-tilt platform 2 drives the camera 3 and the detection device 4 to rotate; the detection device 4 includes a laser emitting module and a processing device, the laser emitting module is used to emit an infrared light beam, and the processing device includes a laser receiving module, a processor, a memory, a wireless communication module, and a power supply module. The laser receiving module is used to receive the reflected light of the laser emitted by the laser emitting module at the location of the methane gas, and sense the change in the methane gas concentration through the processor to obtain the methane concentration. The laser receiving module, memory, wireless communication module, and power supply module are all electrically connected to the processor; the camera 3 is electrically connected to the detection device 4; the detection device 4 is also connected to the monitoring center through the wireless communication module.

[0027] Specifically, the laser emission module includes a laser, and the laser includes several lasers.

[0028] Since the output signal of the laser receiving device is relatively weak and easily affected by various environmental noises, the output signal of the laser receiving device must be amplified and filtered. The utility model provides an amplifier, a high-pass filter, and a low-pass filter between the laser receiving module and the processor. The amplifier is used to amplify the signal output by the laser receiving module, the high-pass filter is used to filter out low-frequency signals, and the low-pass filter is used to filter out high-frequency signals.

[0029] Specifically, the amplifier uses an LM358 operational amplifier.

[0030] Specifically, the wireless communication module includes a 4G / 5G wireless network communication module.

[0031] Specifically, the monitoring center includes a host computer and a server.

[0032] Specifically, the detection device 4 is further provided with a temperature sensor, a humidity sensor, and a flame detector, and the temperature sensor, humidity sensor, and flame detector are all electrically connected to the processor.

[0033] Specifically, the processor is a single chip microcomputer.

[0034] Specifically, the detection device 4 is further provided with an alarm, which is electrically connected to the processor. Figure 3 As shown, when the gas concentration detected by the instrument reaches the preset alarm value, the single chip microcomputer sends a high level signal to control the transistor Q. At this time, the transistor Q is turned on, the LED emits a flashing red light, and the speaker SP1 emits a sound to alert the staff.

[0035] When the utility model is working, the electric pan-tilt platform is set on the vertical pole 1, and the upper computer controls the electric pan-tilt platform to carry the laser detector and the camera to realize rotation. The laser emission module emits laser to the target part (such as pipeline, valve, etc.) of the gas station. The wavelength of the laser is controlled at the corresponding methane gas absorption peak. After being absorbed by the methane gas, diffuse reflection waves are caused in the pipeline, valve and other parts. After being emitted, the laser enters the laser receiving module and the processor senses the change of methane gas concentration, thereby realizing the detection of methane concentration. It is determined whether to alarm according to the real-time detected methane gas concentration value, and the alarm record is saved. The camera is used to capture the real-time scene picture of the alarm position to quickly locate the approximate leakage area.

[0036] The utility model also uses temperature and humidity sensors to detect ambient temperature and humidity data, sending them to a processor for data processing. The processor determines whether the ambient temperature and humidity data exceed set thresholds. If so, an alarm is activated and the result is transmitted to a host computer via a wireless communication module, allowing staff to promptly address the situation and prevent environmental impacts on natural gas storage.

[0037] The utility model also uses a flame detector to detect whether a fire occurs in the environment and sends it to the processor. The processor sends the result to the host computer through the wireless communication module. The staff can check it in time and deal with it in time if any abnormality occurs to avoid danger.

[0038] It should be noted that the various unit components used in the present invention are all existing products and are not limited to specific models.
