Description

Technical Field

[0001] The utility model belongs to the technical field of controllers, and in particular relates to an integrated multifunctional central controller. Background Art

[0002] The central controller, as the neural control system of modern AV system, is an indispensable and important part of AV systematization, large-scale and networking. An AV system, no matter how large or small it is, and no matter how many devices it has, is a system with low efficiency without the central control system. With the addition of the central control system, the AV system has an "intelligence" level, and to a certain extent reduces the number of people required for management and operation of the system, and also reduces the workload of managers. However, it was not until the central control system entered the networking development stage in recent years that the AV system entered a stage of perfect function. It is the development of networking that makes the control function of the central control system omnipresent, humanized and intelligent. With the popularization and standardization of IP networks, AV systems have begun to adopt a large number of IT technologies: DSP, Category 5 cables, and IP switching technologies have been fully introduced into AV systems. AV systems can not only be controlled through the network, but also interact with the control system.

[0003] The internal structure of the existing central controller is relatively complex, integrating multiple lines and external devices, and the outer shell and top cover of the central controller are usually installed with bolts. However, when the central controller needs to be repaired, the outer shell and the top cover need to be disassembled, but the bolts are slow to disassemble, which affects the maintenance efficiency of the central controller and causes certain impacts. In addition, most of the existing central controllers can only perform single device connection control, resulting in poor results.

[0004] Therefore, there is a need for an integrated multifunctional central controller to solve the problems of slow installation and disassembly and relatively single functions of the central controller in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with embodiments.

[0021] See also Figure 1-4 The utility model provides an integrated multifunctional central controller, including a bottom box 1 and a top cover 14. A bottom plate 6 is arranged at the bottom end of the inner wall of the bottom box 1, a DC interface 2 is opened on one side of the outer wall of the bottom box 1, heat dissipation ports 3 are opened on both sides and the bottom of the outer wall of the bottom box 1, a relay 5 is arranged at the front end of the inner wall of the bottom box 1, a high and low level jumper cap 4 is arranged in the middle of the bottom box 1, an STM32 main control IC9 is arranged at the rear side of the inner wall of the bottom box 1, an auxiliary function IO interface 10 is arranged on the outer wall of the STM32 main control IC9, a speaker 11 is arranged on one side of the STM32 main control IC9, a guard plate 12 is fixed to the top of the bottom box 1, and bayonet 13 is opened on both sides of the guard plate 12, protective pieces 16 are fixed at both ends of the outer wall of the top cover 14, and a quick release mechanism 17 is arranged on the inner wall of the protective piece 16.

[0022] The quick-release mechanism 17 can mainly realize quick disassembly and installation of the bottom box 1 and the top cover 14 , thereby improving the work efficiency of maintenance personnel.

[0023] Further as Figure 2 , Figure 3 As shown, it is worth explaining in detail that the quick release mechanism 17 includes two movable grooves 171, and the two movable grooves 171 are respectively opened on the inner wall of the protective member 16. A limit block 172 is slidably installed on the inner wall of the movable groove 171, and a pulling rod 174 is fixed to one end of the limit block 172. The outer wall of the pull rod 174 is provided with an extrusion spring 173, and the other end of the limit block 172 is fixed to a locking rod 175.

[0024] By pulling the pull rod 174, the limit block 172 can be driven to slide toward the outer wall of the movable groove 171, and then the limit block 172 can drive the locking rod 175 to slide, so that the locking rod 175 slides out of the inner wall of the bayonet 13, thereby enabling the bottom box 1 and the top cover 14 to be quickly disassembled.

[0025] Further as Figure 2 As shown, it is worth to explain in detail that one end of the extrusion spring 173 is fixed to the limit block 172 , and the other end of the extrusion spring 173 is fixed to the inner wall of the movable groove 171 .

[0026] This scheme has the following working process: when it is necessary to repair the accessories on the inner wall of the bottom box 1, in order to improve the maintenance efficiency, first pull the pull rod 174, thereby driving the limit block 172 to slide against the outer wall of the movable groove 171, and then drive the locking rod 175 to slide through the limit block 172, so that the locking rod 175 slides out of the inner wall of the bayonet 13, thereby enabling the bottom box 1 and the top cover 14 to be quickly disassembled. When it is necessary to install, the guard plate 12 is engaged with the slot 15, and then the pull rod 174 is pulled, so that it can drive the extrusion spring 173 to limit and squeeze through the limit block 172. At the same time, when the guard plate 12 and the slot 15 are completely overlapped, release the force point of the pull rod 174, so that it drives the limit block 172 and the locking rod 175 to reset through the extrusion spring 173, thereby enabling the top cover 14 and the bottom box 1 to be quickly installed.

[0027] According to the above working process, it can be known that: by setting the high and low level jumper caps 2, and then connecting to 5V10A DC through the DC interface, the device starts to work, and the OLED screen display 7 shows the working status and device IP. The auxiliary function IO interface 10 can be connected to RS232 and RS485 and other peripheral control relays 5, and can also be controlled by infrared IR through the IR hole 8. When the working status of the device changes, the speaker will also report the current changed status, thereby improving the diversity of the central controller.

[0028] Further Figure 2 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that the engaging rod 175 is engaged with the bayonet 13 .

[0029] The engaging rod 175 can mainly engage with the bayonet 13 , so that the top cover 14 and the bottom plate 1 can be quickly installed and removed.

[0030] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that an OLED display screen 7 is arranged on the rear side of the outer wall of the bottom box 1, and an IR hole 8 is opened on one side of the OLED display screen 7.

[0031] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that a slot 15 is provided at the bottom end of the top cover 14 , and the slot 15 is engaged with the guard plate 12 .

[0032] In summary: through the coordination between various integrated line interfaces, such as the DC interface 2, the IR port 8, and the auxiliary function IO interface 10, the multi-function of the central controller is reflected, thereby further improving the practicality and flexibility of the central controller.
