Wellhead real-time monitoring alarm for geophysical prospecting

Abstract

The invention discloses a real-time monitoring alarm for a geophysical prospecting wellhead. The real-time monitoring alarm comprises a central data processing unit, a balance vibration detection unit, an impact detection unit, a wireless communication unit, a GPS positioning unit, a vertical placement detection unit, a state display unit and a power supply unit, the central data processing unit is used for data analysis and processing, the balance vibration detection unit is used for detecting the posture direction change of the alarm, and the impact detection unit is used for detecting whether the shell of the alarm is knocked and vibrated by external force; the wireless communication unit is used for link communication among the alarm, a mobile phone and a server, and the GPS positioning unit is used for positioning the alarm; the vertical placement detection unit is used for ensuring correct burying of the alarm; the state display unit is used for indicating electric quantity and alarm information; the power supply unit is used for supplying power to the whole machine. According to the invention, an alarm signal is directly transmitted to a communication base station of a mobile phone, the limitation of short alarm distance is broken through, and more reliable timeliness is achieved.

Description

technical field [0001] The invention relates to a real-time monitoring and alarm device for a geophysical wellhead, belonging to the technical field of geophysical exploration. Background technique [0002] In the current geological exploration, artificial seismic waves are mainly used to find oil or gas, which mainly includes steps: 1. Measurement, 2. Drilling, 3. Placing explosives, 4. Shooting, 5. Collecting data, 6. Analyzing data Wait. [0003] At present, the existing gun shaft explosives monitoring products used in the field use the communication method of LORA networking during the alarm process. However, this LORA communication method has two disadvantages: [0004] First, the communication distance of LORA is short. Generally speaking, the farthest transmission signal of LORA is claimed to be about 20 kilometers. However, to achieve this communication distance, a very good transmitting and receiving position is required, such as the one erected on the top of the m...

[0005] Second, the LORA method cannot directly communicate with mobile phones or servers. It needs something called a gateway to transfer signals, which will easily cause delay or loss of alarm signals.

This may cause the delay or l
