[0033] As introduced in the background technology, the traditional box-type distribution automation terminal has a unified outer box with a fixed number of board slots such as power boards, CPU boards, analog quantity acquisition boards, and digital quantity acquisition boards. The slot positions are relatively fixed and the number is limited. The scalability and configuration flexibility are low, and the cost of equipment upgrades is high, which makes it impossible for the distribution automation terminal equipment to dynamically or statically meet the changes in actual application needs of the engineering site.

[0034] In order to solve the above problems, the utility model provides a configured intelligent power distribution terminal, including multiple independent hardware function modules and multiple configured spliced ​​bases, multiple bases are connected by signals based on the backplane bus, each base is provided with a unified bus interface, and multiple hardware function modules are respectively connected by signals with multiple bases through the unified bus interface.

The module installation is no longer limited by the chassis size and the number of slots. Therefore, the type and number of modules can be arbitrarily configured according to the needs, which can greatly reduce the operation and maintenance workload, thereby saving the construction and operation and maintenance costs of power distribution automation; at the same time, due to its advantages such as reusability and scalability, the cost of equipment expansion and transformation is greatly reduced, thereby extending the life cycle and use cycle of the equipment.

[0035] The above-mentioned configured intelligent power distribution terminal is described in detail below through specific embodiments.

The intelligent power distribution terminal adopts backplane bus technology and configuration-based design. Since each base 20 is provided with a unified bus interface, the number and type of hardware function modules 10 of the intelligent power distribution terminal can be freely configured according to the application requirements such as the number of lines, communication mode, and external device type at the application site, and various types of hardware function modules 10 can be arbitrarily combined with the base 20.

[0037] like Figure 2 As shown, in this embodiment, a plurality of hardware function modules 10 are provided with guide rail slots 29 on their backs, and the plurality of hardware function modules 10 are configured and installed through the guide rail slots 29 , so that the hardware function modules 10 can be conveniently installed and removed on the guide rails.

[0038] like Figure 3 As shown, the base 20 is provided with a module guide hole 21, a PCB connector 22, a bus connector 25 and a bus connector 26. The bus connector 25 of one base is connected to the bus connector 26 of another base, so that the signal connection between the bases 20 based on the backplane bus can be realized. The base 20 is also provided with a base guide hole 23 and a base guide column 24. The base guide hole 23 of one base is connected to the base guide column 24 of another base to realize the mechanical connection between the bases 20. Each base can be easily assembled, and the bases can be spliced ​​and aligned through the base guide hole 23 and the base guide column 24. During the splicing process, the bus connector 25 and the bus connector 26 are docked. There are two connecting screws 28 in each group, and the two bases 20 are fixed by the connecting screws 28.

[0039] like Figure 4As shown, the hardware function module 10 is provided with a module guide column 11 and a PCB connection seat 12. The module guide hole 21 of the base 20 is connected to the module guide column 11 of the hardware function module 10, and the PCB connector 22 of the base 20 is connected to the PCB connection seat 12 of the hardware function module 10, which serves as a bus interface for signal connection between the base 20 and the hardware function module 10. The hardware function module 10 is provided with a card seat 13, and the base 20 is provided with a corresponding buckle 27. One end of the base 20 and the hardware function module 10 are fixed to the card seat 13 through the buckle 27, and the other end of the hardware function module 10 is fixed through the locking screw 14. Each hardware function module 10 can be conveniently installed on the base 20, and the module and the base 20 are spliced ​​and aligned through the module guide hole 21 of the base 20 and the module guide column 11 at the bottom of the module.

The quick-connect connector and the quick-connect connector seat are not required for each module and can be cancelled on a specific module, but it does not affect the configurable design of the terminal and the rapid replacement or expansion of the module.

[0042] The utility model adopts a modular design in structure. A unified bus interface is used for communication between modules. The modules are placed inside the terminal in a pluggable form. The type and quantity of modules can be configured according to the actual needs of the engineering site. Since the chassis plug-in board structure design is no longer adopted, the engineering site can arbitrarily expand and assemble the modules according to the needs.
