Abstract
Description
Technical Field
[0001] This application relates to the field of power supply systems, and more particularly to embedded power supply systems. Background Technology
[0002] In traditional test equipment, especially signal conditioning equipment for door tooling mechanism controllers, the device under test (DUT) is typically powered by an external, independent power supply. This design approach has several significant limitations, particularly in terms of portability and adaptation costs. External power supplies are often bulky, making them difficult to carry and move, which is a significant disadvantage when frequent equipment relocation or testing in space-constrained environments. The size and weight of the external power supply limit the overall portability and flexibility of the test equipment, impacting testing efficiency and the ease of deploying the test environment.
[0003] Furthermore, external circuitry is required to coordinate with the signal conditioning equipment to achieve current and voltage detection and power on / off control. This necessitates additional circuit design, wiring, and interfaces, increasing system complexity and cost. The addition of external circuitry not only raises system costs but also complicates debugging and maintenance. When using an external power supply, ensuring proper connection and compatibility between the power supply and signal conditioning equipment is crucial. This involves multiple interfaces and wiring, increasing connection complexity and the risk of errors. In practice, incorrect connections can lead to test failures or equipment damage.
[0004] Therefore, the external independent power supply used in the existing technology has obvious shortcomings in terms of portability, adaptation cost, connection complexity, integration and ease of field deployment. Utility Model Content

[0019] Please refer to the following: Figure 1 An embedded power supply system is used for signal conditioning equipment capable of testing the controller of the hatch tooling mechanism. The signal conditioning equipment includes a signal conditioning box, and the embedded power supply system includes a DC power supply, a shorting wire 2, a power on / off control module, a voltage acquisition module, and a current acquisition module.
[0020] The signal conditioning box includes a front panel 11 and a rear panel 12. A positive detection terminal 111 and a negative detection terminal 112 are fixed on the outer side of the front panel 11. The positive detection terminal 111 and the negative detection terminal 112 can be connected through the jumper wire 2, and both the positive detection terminal 111 and the negative detection terminal 112 can be detachably connected to the jumper wire 2. The rear panel 12 is fixed with a grounding terminal and a cable connection socket group. The cable connection socket group includes at least one cable connection socket for connecting the power supply cable of the product under test. The front panel and the rear panel are part of the signal conditioning box, but the positive detection terminal, the negative detection terminal, the grounding terminal and the cable connection socket group are all part of the embedded power supply system.
[0021] The DC power supply, power on / off control module, current acquisition module, and voltage acquisition module are all fixed inside the signal conditioning box. The positive terminal of the DC power supply is connected in sequence to the power on / off control module and the positive detection terminal 111. The negative terminal of the DC power supply is connected in sequence to the cable connection socket group, the current acquisition module, and the negative detection terminal 112. The voltage acquisition module is connected in parallel with the cable connection socket group. The negative terminal of the DC power supply is also connected to the grounding terminal. Grounding can reduce the risk of electric shock and fire while maintaining circuit voltage stability.
[0022] Specifically, the power supply on / off control module includes a relay and a relay driver chip connected to the relay. The relay can control the connection between the positive terminal of the DC power supply and the positive detection terminal 111, and the relay driver chip can drive the relay.
[0023] Specifically, the voltage acquisition module includes a first data acquisition card capable of detecting the voltage value of the input voltage signal, the current acquisition module includes a Hall current sensor and a second data acquisition card capable of detecting the voltage value of the input voltage signal, and the power line connecting the cable connection socket group and the negative detection terminal 112 passes through the hole in the middle of the Hall current sensor.
[0024] Specifically, the first data acquisition card and the second data acquisition card are the same multi-terminal data acquisition card, which can acquire at least two voltage signal values.
[0025] Specifically, the shorting wire 2 includes a connecting wire and a plug. A plug is fixed at each end of the connecting wire. The positive detection end 111 is provided with a first slot adapted to the plug, and the negative detection end 112 is provided with a second slot adapted to the plug.
[0026] Specifically, the plug is a banana plug.
[0027] The DC power supply, power on / off control module, voltage acquisition module, and current acquisition module are all integrated inside the signal conditioning box. This allows it to replace an external independent power supply for the device under test (DUT) while meeting the signal conditioning equipment's testing function requirements. Specifically, it enables power on / off control and voltage and current acquisition and detection. Therefore, the embedded power supply system improves integration and portability, facilitating field deployment. Furthermore, since the DC power supply, power on / off control module, voltage acquisition module, and current acquisition module are all located inside the signal conditioning box, no external adapter modules are needed for connection, reducing mutual adaptation costs and avoiding complex connections between different circuit modules when setting up the test environment, which is beneficial for field deployment. In addition, a jumper wire 2 is provided. Jumper wire 2, in conjunction with the positive detection terminal 111 and the negative detection terminal 112, allows for series or parallel connection of external test equipment without disassembling the signal conditioning box, providing convenience for external equipment to detect current and voltage. This facilitates the setup of the test environment and the verification of test data. Moreover, in special circumstances, power can be cut off by unplugging jumper wire 2. In summary, this application can improve portability and integration while reducing adaptation costs, connectivity complexity, and on-site deployment difficulty.
