Abstract
Description
Technical Field
[0001] This invention relates to the field of guardrail technology, specifically to an electronically linked guardrail. Background Technology
[0002] Traditional security fences mostly only provide physical isolation, have simple structures, and lack effective monitoring and linkage control mechanisms. In scenarios requiring real-time monitoring and rapid response, such as around important facilities, warehouses, and residential areas, traditional security fences cannot detect intrusions in a timely manner and take corresponding measures, making it difficult to meet the growing security needs.
[0003] Some existing guardrails with electronic functions have imperfect control circuit designs, lack necessary protection devices and status indication functions, resulting in poor system stability and reliability. Furthermore, the remote control method is not flexible and convenient enough, which affects the actual use effect of the guardrails.
[0004] Therefore, the development of an electronically linked safety barrier has become an urgent problem to be solved. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide an electronically linked guardrail with a complete electronic control circuit, which can realize remote monitoring and linkage control, improve the timeliness and effectiveness of safety protection, and enhance the stability and reliability of the system.
[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: an electronic linkage guardrail, including a control circuit and a guardrail;
[0007] The control circuit includes an air switch, an AC contactor, a relay, and a remote control unit. The air switch is connected to a power source, the AC contactor is connected to the air switch, the relay is connected to the AC contactor, and the remote control unit is connected to the relay.
[0008] The guardrail includes a support frame and an infrared controller. The infrared controller is wirelessly connected to a remote control unit. The infrared controller includes a transmitter and a receiver. The support frame has two parallel supports. The transmitter and receiver are fixed on one support frame and are positioned opposite each other.
[0009] Furthermore, the control circuit also includes a fuse that connects the power supply to the air switch.
[0010] Furthermore, the air switch is either a 380V air switch or a 220V air switch, with the 380V air switch connected to a 380V AC power supply and the 220V air switch connected to a 220V AC power supply.
[0011] Furthermore, the control circuit also includes an indicator light, which is connected to an AC contactor and a relay.
[0012] Furthermore, the remote control unit includes a remote controller and a remote control antenna, a start button, and a stop button electrically connected thereto.
[0013] Furthermore, it also includes a terminal block, which is used to control the connection of terminals between various components in the circuit.
[0014] The advantages of this invention compared to the prior art are:
[0015] This invention uses an infrared controller to monitor the protected area in real time. Once an intrusion is detected, the signal can be quickly transmitted to the remote control unit and trigger corresponding linkage control measures (i.e., quickly cut off the power to the equipment). If an alarm is issued, it can promptly remind relevant personnel and effectively prevent the occurrence of safety accidents.
[0016] The control circuit of this invention incorporates multiple protection devices, including fuses and air switches, which can promptly cut off the power supply in case of overload, short circuit, or other abnormal conditions, protecting components from damage and improving system stability and reliability. Simultaneously, indicator lights allow operators to monitor the circuit's operating status in real time, facilitating timely fault detection and handling.
[0017] This invention's remote control unit employs wireless communication, allowing operators to control the guardrail from a distance without needing to operate it close to the site, thus improving control flexibility and convenience. The inclusion of start and stop buttons also meets the needs of on-site operation, increasing control versatility. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0025] The following is a detailed description of an electronically linked protective barrier according to the present invention, with reference to the accompanying drawings.
[0026] Combined with appendix Figure 1-4 The specific implementation process of the electronic linkage guardrail of the present invention is as follows:
[0027] An electronically linked guardrail mainly consists of two parts: a control circuit and the guardrail itself.
[0028] The control circuit is the core component of this invention, and its specific composition and connection relationship are as follows:
[0029] The control circuit is connected to the power supply via fuse 7. Fuse 7 provides overload and short-circuit protection. When an abnormal current occurs in the circuit, fuse 7 will quickly melt, cutting off the circuit and protecting downstream components from damage. Fuse 7 is connected to an air switch, which can be either a 380V air switch 1 or a 220V air switch 2, corresponding to either a 380V AC power supply or a 220V AC power supply, depending on the actual usage scenario and power supply conditions. The air switch has overload, short-circuit, and undervoltage protection functions, further ensuring the safe operation of the circuit.
[0030] AC contactor 3 is connected to an air switch, relay 4 is connected to AC contactor 3, and the remote control unit is connected to relay 4. AC contactor 3 is used to control the on / off state of the circuit and realizes automatic control of high-current circuits by receiving control signals; relay 4 is mainly used to transmit control signals, and plays the role of signal amplification and isolation. It can convert the weak control signals of the remote control unit into signals that can drive AC contactor 3 to operate, thereby achieving the purpose of controlling or protecting the circuit.
[0031] The indicator light 8 is connected to the AC contactor 3 and the relay 4, and is used to indicate the working state of the control circuit. When the circuit is working properly, the indicator light 8 lights up, facilitating the operator to intuitively understand the system operation; if the indicator light 8 goes out or flashes abnormally, it indicates that there may be a fault in the circuit and needs to be checked and repaired in time.
[0032] The remote control unit includes a remote controller 9 and a remote control antenna 10, a start button 11, and a stop button 12 electrically connected thereto. The remote control antenna 10 is used to receive and transmit wireless signals to achieve wireless communication between the remote control unit and the infrared controller 6 in the guardrail; the start button 11 and the stop button 12 facilitate the operator to directly control the start and stop of the guardrail on site, increasing the flexibility of control.
[0033] The guardrail part includes a support frame 5 and an infrared controller 6:
[0034] There are two support frames 5 which are arranged in parallel, providing a stable installation foundation for the infrared controller 6. The material of the support frame 5 can be selected according to actual needs, such as metal, plastic, etc., to ensure a certain strength and stability.
[0035] The infrared controller 6 is wirelessly connected to the remote control unit, including a transmitting end and a receiving end. The transmitting end and the receiving end are respectively fixed on a support frame 5 and are arranged opposite to each other. When an object enters the infrared detection area between the transmitting end and the receiving end, the infrared signal is blocked, and the infrared controller 6 sends the detected signal to the remote controller 9. The remote controller 9 controls the actions of the AC contactor 3 and the relay 4 according to a preset program, thereby realizing the interlocking control of the guardrail, such as sounding an alarm, cutting off the power supply, etc.
[0036] The electronic interlocking guardrail of the present invention further includes a wiring board 13, and the wiring board 13 is used for connecting the wiring terminals between various devices in the control circuit. Through the wiring board 13, the lines of various devices can be conveniently sorted out and connected, making the circuit layout clearer, facilitating installation, debugging and maintenance, and at the same time improving the reliability and stability of the circuit connection.
[0037] For the convenience of users, the remote controller 9 has a corresponding mobile phone APP. Through the mobile phone APP, the operation status of the remote controller 9 can be viewed. When an object enters the infrared detection area between the transmitting end and the receiving end, the infrared signal is blocked, and the infrared controller 6 sends the detected signal to the remote controller 9. The remote controller 9 then sends the detection result to the mobile phone APP and prompts the detection time.
[0038] In practical applications, users can also add a camera. After observing the on-site situation through the camera, they can then go to the site to operate the start button 11 and the stop button 12.
[0039] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
