Description

Technical Field

[0001] This utility model relates to the field of industrial high-speed door technology, specifically to an industrial high-speed door radar-triggered start-up backup power supply device. Background Technology

[0002] Industrial high-speed doors are a type of door product designed specifically for industrial environments, characterized by high speed, high frequency, and high performance. The most commonly used industrial high-speed door is the high-speed roller shutter door, which has a structure in which the door body rolls up along the tracks on both sides of the door opening and is stored in the top roller.

[0003] The main structure of an industrial high-speed door generally includes a drive system, a door curtain, a control box, and a backup power supply. The control box is connected to external devices such as radar and remote control, and is also connected to the drive system. This allows the radar to sense and control the opening and closing of the door curtain. The backup power supply is connected to the mains power and is then connected to the control box to provide DC power to the control box in the event of a power outage. This ensures that the industrial high-speed door can temporarily open normally during a power outage, thus guaranteeing safe operation.

[0004] In actual use, when the mains power fails, the backup power supply generally has four working modes. First, the backup power supply automatically starts the inverter once after the power outage, and after a certain period of time, it sends an opening signal to the control box to control the automatic opening of the curtain. This method is not frequently used in actual use due to the risk of unattended operation. Second, manual start is achieved by pressing the start button on the backup power supply to start the inverter. In this method, since both the control box and the backup power supply are located on the wall inside the curtain, it is impossible to start manually if someone is on the outside. Third, an external start switch is connected to the outside of the roller shutter door to start the inverter. This method is also rarely used because installing the start switch requires drilling holes and is unsafe. Fourth, the backup power supply is started via remote control. In this method, it is difficult to start the backup power supply if the operator does not have the remote control with them.

[0005] Therefore, the above-mentioned methods for starting up the backup power supply all have some problems in actual use, which leads to inconvenience in use. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an industrial high-speed door radar-triggered backup power supply device. This device can utilize the existing radar sensing system to trigger the backup power supply when a person approaches the radar sensing area in the event of a power outage, thereby enabling the high-speed door to open normally. It is easy to operate and requires no additional hardware modifications.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An industrial high-speed door radar-triggered backup power supply device includes a backup power supply housing, a battery module, an MCU module, a manual port, and a radar sensor. The battery module, MCU module, and manual port are all integrated inside the backup power supply housing. The radar sensor is mounted on the upper outer side of the industrial high-speed door. The battery module is electrically connected to the MCU module, providing backup power to the MCU module and its control circuitry. The manual port is electrically connected to the MCU module and also interfaces with the radar interface on the existing control box of the industrial high-speed door. The radar sensor is connected to the manual port via a cable, and the manual port provides it with operating power. The MCU module receives sensing signals from the radar sensor in real time through the manual port. The MCU module also establishes a control connection with the industrial high-speed door control box, used to generate and send door curtain opening and closing commands to the control box based on the radar sensing signals.

[0009] Furthermore, the manual port integrates a first radar signal interface and a first power supply interface. Correspondingly, the radar sensor is provided with radar signal terminals and power supply terminals. The first radar signal interface is connected to the radar signal terminals of the radar sensor via a signal line for transmitting personnel detection signals. The first power supply interface is connected to the power supply terminals of the radar sensor via a power line for supplying it with operating power.

[0010] Furthermore, the MCU module is connected to a switching circuit. This switching circuit includes an AC power interface, a control box interface, and a backup power interface. The AC power interface connects to external AC power; the control box interface connects to the industrial high-speed door control box, providing it with main operating power; and the backup power interface connects to the power output terminal of the MCU module. This switching circuit enables automatic and seamless switching between AC power and backup power.

[0011] Furthermore, the manual port is preferably located on the lower panel of the backup power supply box to facilitate on-site wiring and routine maintenance.

[0012] Furthermore, the radar interface of the control box includes a second radar signal interface. The first radar signal interface of the manual port is connected to this second radar signal interface to ensure that the radar sensing signal can be received and processed simultaneously by the control box (when the mains power is normal) and the MCU module (when the power is off).

[0013] Furthermore, the battery module is composed of several lead-acid batteries connected in series, which has the advantages of low cost, stable performance, and sufficient capacity.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes the existing radar sensor installed outside the door. In the event of a power outage, simply approaching the radar sensing area triggers the backup power supply and opens the door curtain, eliminating the need for additional operations (such as pressing buttons or searching for a remote control). This significantly improves user experience and passage efficiency. Furthermore, the battery, MCU, and manual port are integrated into the backup power supply box, allowing direct connection to the radar interface of the control box via the manual port. This eliminates the need for significant modifications to the existing high-speed door structure or control system, making installation convenient and facilitating widespread adoption.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1 As shown, the industrial high-speed door radar-triggered backup power supply device of this utility model is physically housed in a standard backup power supply box 1. The box 1 integrates three core components: a battery module 2, an MCU module 3, and a manual port 4. The battery module 2 preferably consists of multiple 12V lead-acid batteries connected in series to provide the required voltage and capacity. The MCU module 3, serving as the control center, can be a microcontroller box (e.g., an STC series or STM32 series microcontroller) with the necessary I / O interfaces and logic processing capabilities. The manual port 4, as an important external interface, is preferably installed on the lower panel of the backup power supply box 1 for easy cable connection.

[0021] As the system's "sensing organ," the radar sensor 5 is installed in the same position as traditional industrial high-speed door systems, typically fixed to the wall or door frame above the outside of the door opening, and is used to detect moving objects in the area in front of the door.

[0022] like Figure 1As shown, manual port 4 integrates two functional interfaces: a first radar signal interface 41 and a first power supply interface 42. Control box 6 is the original main control box of the industrial high-speed door, which has a standard radar access interface, including at least one second radar signal interface 61. The radar sensor 5 has two terminals: a radar signal terminal 51 and a power supply terminal 52.

[0023] The electrical connections of the system are as follows: The first radar signal interface 41 of manual port 4 is connected to the second radar signal interface 61 of control box 6 via a signal cable, and also to the radar signal terminal 51 of radar sensor 5. The first power supply interface 42 of manual port 4 is connected to the power supply terminal 52 of radar sensor 5 via a power cable. This connection method makes manual port 4 a critical signal and power relay hub.

[0024] The MCU module 3 is connected to the internal circuitry of the manual port 4 via its I / O port, enabling it to read signals from the first radar signal interface 41 and control the power supply to the first power supply interface 42. Simultaneously, the MCU module 3 is connected to the control box 6 via control lines (e.g., simple dry contact signal lines or RS485 communication lines) to send door curtain operation commands to the control box 6.

[0025] like Figure 1 As shown, to ensure continuous power supply, a switching circuit 7 is added to the system. This switching circuit 7 can be an automatic switching circuit composed of relays. It has three main interfaces: mains interface 71 connects to the 220V mains input; control box interface 72 connects to the power input terminal of control box 6; and backup power interface 73 connects to the backup power output terminal processed by MCU module 3. When the mains power is normal, the relay is energized, and the mains power supplies control box 6 through control box interface 72. When the mains power fails, the relay is released, cutting off the mains power path. At the same time, MCU module 3 is activated by battery module 2 and provides emergency power to control box 6 through backup power interface 73 and control box interface 72.

[0026] Workflow:

[0027] Normal operation (mains power normal): Mains power supplies control box 6 via switching circuit 7. Control box 6 supplies power to radar sensor 5 through its radar interface (second radar signal interface 61) and the connected manual port 4, and monitors the radar signal in real time to control the normal opening and closing of the door curtain. At this time, MCU module 3 is in monitoring mode, and battery module 2 is in float charging standby mode.

[0028] Emergency Start-up (Main Power Outage): When the switching circuit 7 detects a mains power outage, it automatically switches to the backup power supply mode. The first power supply interface 42 of the manual port 4 continuously provides operating power to the radar sensor 5, enabling it to maintain its detection function.

[0029] Radar triggering: When a person enters the effective detection area of ​​radar sensor 5, radar sensor 5 generates a sensing signal. This signal is transmitted to MCU module 3 through the first radar signal interface 41 of manual port 4.

[0030] Door curtain control: After receiving a valid radar trigger signal, MCU module 3 generates an "open door" command based on preset logic (such as immediate door opening or delayed judgment) and sends it to control box 6 through the control line. Control box 6, driven by backup power, executes the door curtain opening action.

[0031] System Recovery: After personnel pass through, the door curtain can automatically close according to the preset program of MCU module 3 or control box 6. When the mains power is restored, the switching circuit 7 automatically switches back to mains power supply, the system returns to normal working mode, and replenishes the battery module 2 with power.

[0032] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model are within the protection scope of this utility model.
