Description

Technical Field

[0001] The utility model relates to the technical field of acquisition boxes, in particular to an integrated portable amplifier acquisition box. Background Art

[0002] With the continuous advancement of science and technology, the application of electronic devices is becoming increasingly widespread across various fields. In the field of signal acquisition and processing, the requirements for device portability, integration, and performance are also increasing. In traditional signal acquisition systems, amplifiers are usually independent devices, which are bulky and difficult to carry and use in the field. Moreover, traditional acquisition systems often require multiple devices to work together, resulting in complex connections, prone to failure, and occupying a large space.

[0003] In the prior art, an existing integrated portable amplifier acquisition box has unstable excitation voltage power supply end during use, resulting in unstable amplifier signal. When the amplifier excitation voltage signal fluctuates greatly, there is no protection for the circuit end, and the amplifier may burn out. Different signal acquisitions cannot be turned on and off separately, and different signal acquisitions must be connected on-site, which is inefficient and has poor practicality. Utility Model Content

[0004] The utility model mainly provides an integrated portable amplifier acquisition box which can ensure the stability of the amplifier excitation voltage power supply end and can protect the circuit end and can independently open and close different signal acquisitions without the need for on-site connection.

[0006] Preferably, multiple support plates are fixed at both ends of the connecting plate, and mounting plates are fixed to the bottom ends of the amplifier body, transformer, fuse and voltage stabilizing module. The mounting plates are fixed to the support plates by first bolts. Through the setting of the mounting plates and the first bolts, all components can be disassembled individually, which is convenient for individual replacement and maintenance, and is more practical.

[0007] Preferably, a heat sink is installed at the bottom end of the collection box body through a second bolt, and one end of the heat sink is fitted with the connecting plate. The setting of the heat sink makes the heat dissipation effect of the collection box body better. The setting of the second bolt of the toilet cover allows the heat sink to be installed and removed at any time, which is convenient for cleaning and replacement.

[0008] Preferably, a bracket is fixed to the bottom end of the collection box body on the outside of the heat sink, and connecting grooves are provided at the four ends of the bracket. The setting of the bracket can prevent the second bolt from being crushed and damaged when the collection box body is placed, and the setting of the connecting groove will not affect the heat dissipation effect of the heat sink.

[0009] Preferably, the channel-independent quick-plug connector and the channel-independent control switch are respectively arranged at the opposite end of the collection box body, the channel-independent quick-plug connector is arranged on the side close to the transformer, and the channel-independent control switch is arranged on the side close to the fuse. By arranging the channel-independent quick-plug connector and the channel-independent control switch at the opposite end of the collection box body, the channel-independent quick-plug connector and the channel-independent control switch are respectively placed separately to avoid entanglement of the connected lines.

[0010] Preferably, the amplifier body, transformer, fuse, voltage stabilizing module, connector, channel-specific quick-connect connector and channel-specific control switch are all electrically connected via circuits, and the circuits are arranged so that all components can be electrically connected.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] In the present invention, the amplifier body needs to amplify the voltage signal for the output of the engine sensor and collect the signal, such as: high-frequency pressure signal, valve lift signal, stress measurement signal, etc. For the output of the multi-channel signal amplifier body, its excitation voltage is transformed by a transformer, and a voltage stabilizing module is added in the middle for voltage stabilization. Each channel is protected by a series fuse. At the voltage output signal end of each amplifier body, a channel-specific control switch is added, and the signal is connected using a quick-plug channel-specific quick-plug connector. All components are integrated in a box, which is convenient and safe. At the same time, the experimental collection efficiency is greatly improved. The excitation voltage at the sensor amplifier body end is stable, the collected signal is stable, the excitation voltage and power supply voltage at the sensor amplifier body end are stable, each channel is equipped with a fuse, zero damage, and each channel is equipped with a separate switch, which is convenient for collection, modular and compact layout, fool-proof operation, efficient test preparation and measurement, and portable extraction of the integrated measurement box.
