Embodiment Construction

[0015] Describe the present invention below in conjunction with specific embodiment:

[0016] Refer to attached figure 1 And attached figure 2 , a signal conditioning board with electromagnetic shielding function in this embodiment, including a PCI card-shaped circuit board 2 and a shielding case.

[0017] When the circuit board itself is designed, the circuit design of the unit function module is adopted, and the processing of the weak signal part adopts conventional electromagnetic compatibility processing methods such as large and small signal separation, digital filtering, and transformer isolation to ensure that the bottom noise of the circuit board meets the use requirements.

[0018] The shielding case includes a front cover 1 , a rear cover 3 and a baffle 4 . The front cover and the rear cover are made of low-carbon alloy cold-rolled steel plates with a thickness of 0.1mm, which not only reduces weight but also facilitates stamping and forming. The PCI board form f...

Abstract

The invention discloses a signal conditioning board with an electromagnetic shielding function, which comprises a circuit board which is designed by adopting the appearance of a PCI (peripheral component interconnect) board and a shielded enclosure, wherein the circuit board adopts an electromagnetic compatibility processing mode of a conventional circuit, and the shielded enclosure comprises a front cover plate, a rear cover plate and a baffle plate. According to the signal conditioning board, a signal conditioning circuit in a target simulator is designed into a circuit board with the appearance of the standard PCI board, the shielded enclosure is added on the whole circuit board, therefore, the electromagnetic environment of the signal conditioning board in an industrial personal computer is effectively improved, and the equipment failure caused by a weak signal interfered by other electrical signal in the industrial personal computer is avoided. The signal conditioning board is fixed in a PCI groove in the standard industrial personal computer by using the fixed mode of the PCI board, the power supply of the industrial personal computer is directly used to supply power for the signal conditioning board, the whole signal conditioning board meets the installation requirement of the standard industrial personal computer (40 cm * 30cm * 25cm), so that the portable and integrated design of the equipment is realized, and the signal conditioning board is compact in structure, small and light and convenient to carry and used in different places.

Description

technical field [0001] The invention relates to the research field of electromagnetic compatibility design, in particular to a signal conditioning board with an electromagnetic shielding function, which is suitable for supporting equipment of an underwater vehicle self-guidance system. Background technique [0002] The target simulator is a kind of test equipment used in conjunction with the self-guidance system of the underwater vehicle. Simulate various signals such as noise, reverberation, ship radiation noise, target echo, and artificial interference. Currently used target simulators often use digital signal processors or virtual instrument architectures. In order to meet the different requirements of the equipment, further signal conditioning is required for the input and output signals of the standard board. Since the output signal of the signal conditioning is generally a weak signal at the microvolt level, in order to prevent the output weak signal from being inter...
