Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of power management equipment, and in particular to a multifunctional power sequencer. Background Technology
[0002] Existing power sequencers exhibit three key shortcomings in practical applications, making them unsuitable for complex scenarios: 1. Limited functionality: lacks flexible control capabilities. The existing equipment only supports "starting and stopping all channels in a fixed sequence", and cannot control the on / off state of a single channel individually. For example, when only the No. 1 lighting device needs to be turned off for maintenance during a stage performance, the entire sequencer must be turned off, causing other equipment (such as sound systems and projectors) to lose power simultaneously, affecting the continuity of the performance.
[0003] 2. Poor scalability: The maximum number of channels per device is fixed, and cascading expansion is not possible. Traditional sequencers typically have 8-12 channels. If you need to control 20 devices (such as lighting, sound, and LED screens in a large banquet hall), you need to purchase multiple independent sequencers, which leads to problems such as messy wiring and difficulty in synchronization.
[0004] 3. Complex operation: ambiguous status feedback Existing equipment mostly uses monochrome LEDs (which only indicate "on / off"), which cannot distinguish between "normal timing control" and "forced connection" states, leading to user misjudgment (such as mistakenly regarding "pass-through" state equipment as fault disconnection). Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multifunctional power sequencer with modular functional integration and low-cost hardware design.
[0006] To achieve the above objectives, this utility model provides a multifunctional power sequencer, including a sequencer body. The back end face of the timer body is provided with: An input power interface is provided for supplying power to the power sequencer; Multiple output ports for connecting external electrical equipment; The central control interface is used for connecting external third-party control devices; Cascading interface, used to connect two power sequencers to achieve cascading functionality; An external high / low level switch is used to switch high / low levels to perform timing on / off functions; The front end face of the timer body is provided with: The display screen is used to show the power supply voltage in real time. Multiple channel control buttons, each channel control button corresponds to one of the output ports, and has two operation modes: long press to control the through state of the corresponding output port, and short press to control the normal on / off state of the corresponding output port. The bypass button has two functions: full channel control and factory reset. A short press controls the on / off status of all output jacks, while a long press clears all data and restores the default factory mode. Multiple channel indicator lights: Each channel indicator light corresponds one-to-one with each of the aforementioned output ports.
[0007] Furthermore, the front end face of the timer body also includes an air switch.
[0008] Furthermore, the front end face of the timer body also includes a timing switch (7) for controlling the timing on / off of the output port.
[0009] Furthermore, the timing switch is a rocker switch.
[0010] Furthermore, the front end of the sequencer body also includes a bypass indicator light, which lights up when the bypass button is pressed and all output ports are connected, and turns off when any output port is disconnected.
[0011] The present invention adopts the above-mentioned solution, and its beneficial effects are as follows: 1) High functional integration: It integrates single-channel / full-channel control, timing logic, third-party central control, cascading expansion and other functions to meet the needs of complex scenarios such as stage and computer room; 2) Convenient operation: Multiple channel indicator lights and display screens provide real-time feedback on status, and the button logic is clear; 3) Low mass production cost and strong security.

Detailed Implementation
[0015] To more fully illustrate this utility model, a detailed description will be provided below in conjunction with the accompanying drawings. The drawings depict preferred embodiments of this utility model. However, it is worth noting that this utility model is not limited to these specific forms and can be implemented in various ways. These embodiments are provided to enable the reader to gain a deeper understanding of this utility model.
[0016] As attached Figure 1-2 As shown in this embodiment, a multi-functional power sequencer, through optimized structural layout and functional design, achieves the integration of single-channel / full-channel control, timing logic, state memory and extended control, specifically including a sequencer body.
[0017] In this embodiment, the back face of the timer body is provided with: Input power interface 12: adopts a standard AC power interface, supports AC 220V input, and provides working power input for the entire power sequencer.
[0018] Multiple output ports 11: Multiple 10A standard ports are used to connect external power equipment (such as stage lighting, sound, servers and other external power equipment). Each port is independently controlled and supports a maximum current load of 10A.
[0019] Central control interface 8: Located on the left side of the rear end, it adopts the RJ45 interface form and supports the RS485 protocol. It can be connected to third-party devices such as computers and central control hosts to realize remote control and receive and execute external control commands.
[0020] Cascading Interface 9: Two (input / output) interfaces are located side-by-side on the right side of the rear panel, using DB9 interfaces, and connecting two sequencers via dedicated cables. After cascading, the device that triggers the timing start operation first automatically becomes the master, and the other becomes the slave. The total number of channels is expanded to 2n (e.g., 8 channels on a single unit → 16 channels after cascading). The slave strictly synchronizes with the timing logic of the master.
[0021] External high / low level switch 10: Installed in the center of the rear panel, it triggers timing-on and timing-off operations by switching between high and low level states, respectively, providing an external 5V-24V signal for the two-position DIP switch. Switching to the "high level" position triggers the timing-on operation; switching to the "low level" position triggers the timing-off operation, suitable for automated control scenarios. In this embodiment, the front end face of the timing unit body is provided with: Display screen 2 is located at the top center of the front face and is used to display the power supply voltage in real time, so as to facilitate monitoring of the power grid status.
[0022] The timing switch 7 is a rocker switch, installed on the right side of the front face, with two positions: "on" and "off". When switched to the "on" position, it triggers the preset timing logic (such as channels 1 to n being turned on sequentially with a delay of 0.5-2 seconds); when switched to the "off" position, it triggers the reverse sequence shutdown logic (such as channels n to 1 being turned off sequentially with a delay of 0.5-2 seconds).
[0023] Multiple channel control buttons 3, the same number as the output sockets 11, are arranged in a matrix in the middle of the front face. Each channel control button 3 corresponds to one of the output sockets 11 and has two operation modes: long press (≥3 seconds) controls the through state of the corresponding output socket 11 (at this time, the channel does not respond to the timing switch 7 and the full circuit on / off command, and the channel indicator light 5 is red), and short press (≤1 second) controls the normal on / off state of the corresponding output socket 11 (participates in the timing switch logic).
[0024] The bypass button 4 is located in the lower right corner of the front panel. It features a raised design to distinguish it from the regular buttons. It has dual functions: full channel control and factory reset. A short press (≤1 second) controls the on / off state of all output ports 11 (i.e., controls the synchronous on / off state of all non-pass-through output ports 11 to achieve full-channel on / off switching). A long press (≥3 seconds) clears all data and restores the default factory mode.
[0025] Multiple channel indicator lights 5: Each channel indicator light 5 corresponds one-to-one with each of the aforementioned output ports 11. Each channel indicator light 5 is located directly above each channel control button (3), and uses surface-mount LED dual-color lights (red and green dual-color) to indicate the channel status through three states: Light off: Output jack 11 is disconnected; A solid green light indicates that output port 11 is in a normal ON state. A constantly lit red light indicates that output port 11 is in a pass-through state.
[0026] Bypass indicator light 6: A red LED located directly above the bypass button 4. It lights up when the bypass button 4 is pressed briefly and all non-pass-through output ports 11 are connected; it automatically turns off when any non-pass-through channel is disconnected, providing a clear indication of the overall connection status.
[0027] For ease of understanding, let's take a 10-channel sequencer as an example. Its workflow is as follows: 1. Single-channel control process The sequencer here is connected to the input power supply, air switch 1 is in the closed state, and display screen 2 shows the current voltage (e.g., 220V). Specifically, Normal On / Off Control (Short Press Operation): The user briefly presses the control button 3 corresponding to "Channel 1" on the front panel (press duration ≤ 1 second) to switch the corresponding output socket 11 to the on state, powering on the external electrical equipment connected to this output socket; the Channel 1 indicator light 5 changes from off to a solid green light, indicating "normal on state". Additionally, if the control button 3 is pressed again, the output socket 11 is disconnected, and the indicator light 5 turns off.
[0028] Straight-through state control (long press operation): The user presses and holds the control button 3 of "Channel 1" (press time ≥ 3 seconds) until the channel indicator light 5 flashes once, then releases the button. This switches the output socket 11 to "straight-through state" (normally connected mode). At this time, the output socket 11 is not affected by the full-path control of the timing switch 7 and the bypass button 4. When the signal is on, the channel indicator light (5-1) changes from green to red and remains on, indicating "straight-through state". In addition, if it is necessary to exit the straight-through state, press and hold the button again for ≥ 3 seconds. The indicator light (5-1) changes from red to green (normal connection) or turns off (disconnection).
[0029] 2. Cascading Expansion Process Both 10-channel sequencers (A and B) are powered on and connected via a dedicated cable through the cascade interface (9) (A “output” interface → B “input” interface).
[0030] Specifically, 2.1) Master and Slave Identification: The user first switches the timing switch (7) of the first sequencer (A) to the "on" position. The first sequencer (A) triggers the timing on logic (channels 1-10 are turned on with a delay of 0.5 seconds in sequence). Immediately afterwards, the second sequencer (B) detects the timing signal of the first sequencer (A) and automatically identifies itself as a "slave". A is the master. At this time, the total number of channels is expanded to 20, so that when the first sequencer (A) executes the timing on, the second sequencer (B), as a slave, executes synchronously with a delay.
[0031] 3. External Control Process The timer is connected to the computer via the central control interface 8. The computer installs the control software and completes the communication configuration.
[0032] Specifically, 3.1) Single-channel remote control: The computer sends a command to turn on channel 5, and the sequencer accordingly turns on the output port 11 corresponding to "channel 5", and the corresponding channel indicator light 5 lights up green. 3.2) External high / low level trigger: The user switches the external high / low level switch 10 to the "high level" position (connecting a 5V signal); then, the sequencer triggers the timing logic: channels 1-10 are turned on sequentially according to a preset delay (0.5 seconds / channel) until all channels have completed their operation; In summary, the sequencer in this embodiment integrates single / full-channel control, timing logic, third-party central control, cascading expansion, and other functions to meet the needs of complex scenarios such as stages and computer rooms.
[0033] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any modifications or alterations made by those skilled in the art to the technical solution of this utility model without departing from its scope are equivalent embodiments of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from its scope should be covered within the protection scope of this utility model.
