Description

Technical Field

[0001] The invention relates to the technical field of equipment alarm lights, and in particular to an alarm light device capable of displaying the working progress of equipment in real time. Background Art

[0002] Industrial equipment warning lights are mainly used in various types of machine tools, machining centers, automation equipment, medical instruments and equipment, and semiconductor processing equipment. The current main production areas are China, Japan, Germany, South Korea, etc.

[0003] Existing industrial alarm lights can only display the operating status of the equipment. They light up green when working normally, yellow when paused and on standby, and red when a fault alarm occurs. That’s all. When there are many machines and equipment on the work site, all of them are in a green working state. It is difficult to distinguish the working progress of each device, such as when it has just started or is about to end, and it is impossible to effectively mobilize the work efficiency of on-site personnel.

[0004] At present, industrial equipment is widely used. In the actual production process in the factory, it is very common for one person to watch multiple machines. Due to the lack of understanding of the operating progress of each equipment, the order of employees loading and unloading materials is relatively chaotic, the equipment utilization rate is very low, and the resource and energy utilization rate is not high. Summary of the invention

[0005] The purpose of the present invention is to provide an alarm light device which can display the working progress of equipment in real time, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: an alarm light device capable of displaying the working progress of equipment in real time, characterized in that it comprises: External device signal driving circuit.

[0007] Isolation acquisition operation circuit Progress display control circuit.

[0008] The external device signal driving circuit is mainly used to connect the PLC signals such as operation, pause and alarm output by the equipment. Its front stage contains a rectifier circuit, which can input the electrical signal into the driving and acquisition circuit regardless of positive and negative polarity. The voltage is collected together through diodes, and the signals do not interfere with each other. The DC 24V voltage is converted into 3.3V voltage through the voltage regulator module for use by the MCU operation module.

[0009] The isolated acquisition operation circuit converts the electrical signal of the external device into a 3.3V weak current signal through an optical coupler and supplies it to the MCU module for acquisition. The MCU module judges and analyzes the working status and progress of the equipment based on the various status signals collected. By comparing the ratio of the current working time to the previous working time, the number of light grids displayed on the progress bar is calculated.

[0010] The progress display control circuit is composed of an MCU processor, an NPN control tube, and an LED indicator light matrix. The number of light grids calculated by the MCU drives the LED indicator lights to light up the corresponding light groups, and the equipment working progress status is displayed in real time in the form of a decreasing or increasing progress bar.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention adds a more complex control chip to the original simple circuit of the alarm light. The electrical signal collected by the acquisition circuit is then judged by the MCU through the change relationship between various electrical signals. After calculation and processing, the control unit finally controls the number of lights to display the operation progress of the equipment in real time. 1. The information diversity of the signal alarm light is increased; 2. The work sequence of on-site workers is effectively guided; 3. The on-site work efficiency is improved; 4. The present invention is simple to use and does not change the original wiring method; 5. It has a power-off memory function. BRIEF DESCRIPTION OF THE DRAWINGS
