Its principle is that the hyperfine structure energy levels of cesium light will exhibit Zeeman splitting under the influence of an external magnetic field. By accurately measuring the frequency between Zeeman sub-levels, the magnitude of the external magnetic field can be calculated. The cesium optically pumped magnetometer has broad application value in geophysical exploration and military fields, and has very important application value and prospects.

[0003] According to the public announcement (CN206400084U), a novel pump source device for a cesium optical pump magnetometer is disclosed.

[0004] In this existing design, a modular approach using cesium lamp excitation is adopted. However, since the existing color light pump magnetometer needs to be connected to multiple devices to perform data acquisition, it is inconvenient to carry and cumbersome to use, which affects work efficiency.

[0031] In this implementation scheme: A cesium optical pump probe 2 is installed on one side of the data conversion module 1, and a connecting cable 3 is installed on one side of the cesium optical pump probe 2. The end of the connecting cable 3 away from the cesium optical pump probe 2 is slidably connected to the data conversion module 1. A differential satellite receiver RTK4 is installed inside the data conversion module 1, and a tablet computer 5 is also installed on one side of the data conversion module 1. This design makes it easy to hold and carry for field measurements, and the operation is simple and easy to use with an intuitive and clear interface, enabling a single person to complete the data collection work, which is highly efficient and practical.

[0032] Furthermore:

[0033] like Figure 1 As shown:

[0034] In an optional embodiment, the data conversion module 1 and the tablet computer 5 are connected by a signal.

[0035] In this embodiment: because the data conversion module 1 and the tablet computer 5 are connected by a signal, this design is adopted to display the data on the tablet computer 5, making it convenient for staff to observe and process the data.

[0036] Furthermore:

[0037] like Figure 1 As shown:

[0038] In an optional embodiment, both the data conversion module 1 and the cesium optical pump probe 2 are made of non-magnetic materials such as nylon or aluminum alloy.

[0039] In this embodiment: Since both the data conversion module 1 and the cesium optical pump probe 2 are made of non-magnetic materials such as nylon or aluminum alloy, this design enables the equipment to have good wind and sand protection, dust protection, and anti-magnetic measures.

[0040] Furthermore:

[0041] like Figure 1 As shown:

[0042] In an optional embodiment, there are two sets of connecting lines 3, which are symmetrically distributed on one side of the data conversion module 1, and each set of connecting lines 3 is connected to a cesium optical pump probe 2.

[0043] In this embodiment, since there are two sets of connecting lines 3, which are symmetrically distributed on one side of the data conversion module 1, and each set of connecting lines 3 is connected to a cesium optical pump probe 2, this design can increase the efficiency of data acquisition.

[0044] Furthermore:

[0045] like Figure 1 As shown:

[0046] In an optional embodiment, the surface of the data conversion module 1 is further provided with a data download port 6 and an RTK antenna interface 7.

[0047] In this embodiment: the collected data can be downloaded and transmitted through the data download port 6, and the received signal of the differential satellite receiver RTK4 can be enhanced through the RTK antenna interface 7.

[0048] Furthermore:

[0049] like Figure 1 As shown:

[0050] In an optional embodiment, the data conversion module 1 has dimensions of 250 mm (length) × 150 mm (width) × 65 mm (height) and a weight of ≤3.5 kg.

[0051] In this embodiment: Since the dimensions of the data conversion module 1 are 250mm long × 150mm wide × 65mm high and the weight of the data conversion module 1 is ≤3.5Kg, this design makes the data conversion module 1 smaller in size and easier to carry.

[0052] Working Principle: A cesium optical pump probe 2 is installed on one side of the data conversion module 1, and a connecting cable 3 is installed on the other side of the probe 2. The end of the connecting cable 3 away from the probe 2 is slidably connected to the data conversion module 1. A differential satellite receiver RTK4 is installed inside the data conversion module 1. A tablet computer 5 is also installed on one side of the module 1. This design facilitates handling, carrying, and field measurements. The operation is simple and easy to use, with a clear and intuitive interface, allowing a single operator to complete data acquisition efficiently and practically. Because the data conversion module 1 and the tablet computer 5 are connected by a signal, the data is displayed on the tablet computer 5 for easy observation and processing. Since both the data conversion module 1 and the cesium optical pump probe 2 are made of non-magnetic materials such as nylon or aluminum alloy, this design provides excellent protection against wind, sand, dust, and magnetism. There are two sets of connecting cables 3, symmetrically distributed on one side of the data conversion module 1, and each set of cables is connected to... The cesium optical pump probe 2, with this design, increases the efficiency of data acquisition. The acquired data can be downloaded and transmitted via the data download port 6, and the RTK antenna interface 7 enhances the reception signal of the differential satellite receiver RTK4. Because the data conversion module 1 measures 250mm (L×W×H) and weighs ≤3.5kg, this design makes it small and portable. In use, the self-excited cesium optical pump sensor inside the cesium optical pump probe 2 utilizes the Zeeman level splitting phenomenon of alkali metal 'cesium-133' atoms (non-radioactive) under an external magnetic field to achieve highly sensitive magnetic field data measurement through optical magnetic resonance technology. The measured data is transmitted to the data conversion module 1, which is connected to it. The built-in hardware processing unit of the data conversion module 1 calculates and processes the magnetic field data in real time. Combined with the differential satellite receiver RTK4, efficient algorithms and satellite positioning enable one-click image generation.
