Description

Technical Field

[0001] This utility model belongs to the field of industrial automation signal indication, and in particular relates to a tower light with an ASI bus interface. Background Technology

[0002] Tower lights are commonly used signal indicator devices in the industrial and automation fields. They visually display equipment status, process progress, or alarm information through different colors, flashing frequencies, or combinations of sound and light. Currently, each existing tower light requires at least five wires, including power, ground, and three different colored signal wires. This presents the problem of controlling numerous tower light locations with ordinary signal wires, making wiring difficult. Utility Model Content

[0003] In view of this, the present invention aims to propose a tower light with an ASI bus interface to solve the problem of multiple control points and complex wiring of tower lights using ordinary signal lines.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A tower light with an ASI bus interface includes a tower light body and a lamp holder. The bottom of the lamp holder is provided with a cable interface, which is connected to the ASI bus interface of an ASI gateway via a cable. The tower light body is installed on the top of the lamp holder.

[0006] The tower light body includes a tri-color lamp inside. A PCB board is installed at the bottom of the tri-color lamp, and the tri-color lamp is electrically connected to the PCB board. A control chip circuit, a tri-color lamp circuit, and a buzzer circuit are installed on the PCB board. The control chip circuit is connected to the cable interface through a wire. The tri-color lamp circuit is connected to the tri-color lamp through a wire and is used to control the on / off state of the three colors of the tri-color lamp. The buzzer circuit is used to control the buzzer switch.

[0007] Furthermore, it also includes a lampshade assembly, which is installed on the top of the lamp holder, and the tower lamp body is installed inside the lampshade assembly.

[0008] Furthermore, the lampshade assembly includes a lampshade body and a lampshade mounting base. The lampshade mounting base is installed above the lamp holder, the lampshade body is installed on the top of the lampshade mounting base, and the tower lamp body is installed inside the lampshade body.

[0009] Furthermore, the lampshade body is made of transparent PVC or polycarbonate PC.

[0010] Furthermore, the bottom of the lamp holder is provided with several mounting holes.

[0011] Furthermore, the cable is a 1.5mm² flat ribbon conductor.

[0012] Furthermore, the cable is a 1.5mm² ASI type dedicated flat cable.

[0013] Furthermore, the control chip circuit is an ASIC slave chip.

[0014] Compared with existing technologies, the tower light with the ASI bus interface described in this utility model has the following advantages:

[0015] The tower light with the ASI bus interface described in this utility model can control the on / off state of the indicator light in three colors using only one slave chip. The unshielded double-wire line can be a 1.5mm² flat ribbon wire, which is inexpensive; or it can be a 1.5mm² ASI-type dedicated flat cable. This not only makes installation convenient but also greatly reduces the complexity of wiring and further improves the adaptability of this utility model. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 5 As shown, the tower light with an ASI bus interface includes a tower light body 1 and a lamp holder 3. The bottom of the lamp holder 3 is provided with a cable interface, which is connected to the ASI bus interface of the ASI gateway via a cable. The tower light body 1 is installed on the top of the lamp holder 3.

[0029] The tower lamp body 1 includes a tri-color lamp 11 inside. A PCB board is installed at the bottom of the tri-color lamp 11, and the tri-color lamp 11 is electrically connected to the PCB board. A control chip circuit and a tri-color lamp circuit and a buzzer circuit connected to it are installed on the PCB board. The control chip circuit is connected to the cable interface through a wire. The tri-color lamp circuit is connected to the tri-color lamp 11 through a wire. The tri-color lamp circuit is used to control the on and off of the three colors of the tri-color lamp 11. The buzzer circuit is used to control the buzzer switch. The control chip circuit is an existing ASIC slave chip.

[0030] In a preferred embodiment of this utility model, such as Figures 2 to 3As shown, it also includes a lampshade assembly 2. The lampshade assembly 2 is installed on the top of the lamp holder 3. The tower lamp body 1 is installed inside the lampshade assembly 2. In this embodiment, a lampshade assembly 2 can also be installed to protect the tower lamp body 1. Alternatively, the lampshade assembly 2 can be omitted, as long as the material of the tower lamp body 1 meets the requirements for use in industrial environments. The outer shell of the tower lamp body 1 can adopt a partially transparent structure: transparent industrial-grade materials (such as transparent PVC, polycarbonate PC, etc.) are used in the area corresponding to the tri-color lamp 11, which not only meets the requirements of oil resistance, temperature resistance, and impact resistance in industrial environments, but also allows the light to pass through directly; other non-transparent areas use non-transparent engineering plastics or metal materials to ensure structural strength and protection.

[0031] In a preferred embodiment of this utility model, the lampshade assembly 2 includes a lampshade body 21 and a lampshade mounting base 22. The lampshade mounting base 22 is installed above the lamp holder 3. The lampshade body 21 is installed on the top of the lampshade mounting base 22. The tower lamp body 1 is installed inside the lampshade body 21. The lampshade body 21 is usually made of industrial-grade transparent materials such as transparent PVC and polycarbonate PC, which not only meet the requirements of oil resistance, temperature resistance and impact resistance in industrial environments, but also allow light to pass through directly.

[0032] In a preferred embodiment of this utility model, such as Figure 4 As shown, the lamp holder 3 is also provided with several mounting holes 31 at the bottom. In actual use, mounting holes 31 can be provided on the lamp holder 3, which facilitates the installation of the lamp holder 3 to a fixed position.

[0033] In a preferred embodiment of this invention, the cable is either a 1.5mm² flat ribbon conductor or a 1.5mm² ASI-specific flat cable. In this embodiment, the ASI bus does not require a processor; only one slave chip (ASIC slave chip) is needed to control the on / off state of the indicator lights in three colors. As the transmission medium, unshielded two-wire lines are used, with a maximum current of 2A and a maximum voltage of 24V. Two options are available for field use: one is a 1.5mm² flat ribbon conductor, which is inexpensive; the other is a 1.5mm² ASI-specific flat cable, whose main advantage is ease of installation. This significantly reduces wiring complexity. Since each tower light has a slave chip, the ASI gateway can assign a unique address to each ASI tower light. The ASI gateway writes a 1 to the ASI tower light (1 for on, 0 for off), which is unique within the ASI network and stored in the EEPROM on the ASI chip, preserving the address even after power loss. Another highlight is the ability to connect other types of ASI sensor slaves to the ASI bus. It should be noted that "the ASI gateway can assign its own address to each ASI tower light... and other types of ASI sensor slaves can be connected to the ASI bus." This part is existing technology, and its purpose is to further improve the adaptability of this utility model.

[0034] In other embodiments, such as Figure 5 As shown, ASI tower lights can be centrally managed through existing ASI gateways. A single ASI gateway can connect up to 64 ASI tower lights to the bus. Each ASI tower light can be assigned a unique address, allowing for control of specific ASI tower lights on the bus. The ASI gateway can control the on / off state of the three colors of the ASI tower lights and the buzzer switch via slave chips. The ASI gateway writes a 1 to the ASI tower light (1 for on, 0 for off). The advantage of using the ASI bus is that it avoids excessive wiring, provides unified management via a bus, and allows connection to existing industrial MES systems for data upload and download. Each ASI bus group has a maximum of one master station, and each master station can connect to a maximum of 62 slave stations. Using two master stations allows for the control of 124 slave stations.

[0035] In other embodiments, ASI bus management and control of tower lights offers another advantage: the ASI bus can support various types of ASI sensors, including physical switches, touch switches, and human body sensors. These diverse sensors can be connected to an ASI gateway via the ASI bus, enabling flexible expansion of the industrial fieldbus and facilitating the development of diverse industry-specific solutions.

[0036] It should be noted that this utility model only improves the structure of the tower light and does not improve the control program. The control program and electrical components involved are all existing technologies.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
