Description

Technical Field

[0001] The invention relates to an industrial alarm system and method based on a smart bracelet, belonging to the technical field of industrial intelligence. Background Art

[0002] At present, the area of ​​factory workshops is usually large, and the production equipment is numerous and widely distributed. In this environment, timely alarm prompts for equipment failure or abnormal status are crucial to production safety. However, existing alarm methods often have problems such as noise pollution, low information transmission efficiency, and response delay. Several commonly used alarm methods in workshops are as follows: 1. Voice broadcast alarm. In a large workshop, the equipment position number and alarm content are usually broadcast through voice to remind the employees on duty to take corresponding measures. However, this method has many problems: 1. Since voice broadcasts rely on the workers' hearing, there is a risk of missed or misheard, and there is a lack of feedback mechanism, making it difficult to confirm whether the alarm is accurately received. 2. When the staff is processing the previous alarm, the new alarm information may not be processed in time, increasing the possibility of missing the alarm. 3. The frequent broadcasting of voice broadcasts will also increase noise pollution, which will have an adverse effect on the workers' working environment and hearing health.

[0003] 2. Three-color alarm lights. Some equipment operating tables are equipped with red, green, and yellow alarm lights, which respectively indicate normal, shutdown alarm, and warning alarm (no shutdown required). However, this method also has shortcomings: 1. The operating table is usually equipped with a touch screen, and workers must approach the screen to know the specific cause of the alarm, which increases the time to confirm the alarm. 2. When a worker needs to inspect multiple equipment, he must check the status of each machine one by one, which is time-consuming and affects the inspection efficiency.

[0004] 3. Centralized control system (DCS) notification. In some process factories, DCS is usually used to centrally monitor the status of equipment. When an alarm occurs, the dispatcher needs to notify the staff in the corresponding area by phone or intercom. However, the limitations of this method include: 1. The dispatcher needs to query and manually notify the on-duty personnel in each area of ​​the day, which increases the workload and the possibility of false notifications. 2. When cross-regional alarms occur intensively, it is difficult for limited dispatchers to accurately and efficiently notify each relevant staff member. 3. During the alarm processing process, in order to deal with the failure of equipment in multiple areas, on-site staff need to frequently communicate with the dispatcher, occupying the frequency band resources of the intercom equipment. Summary of the invention

[0005] Based on the above, the present invention provides an industrial alarm system and method based on a smart bracelet to solve the problems of noise pollution, delayed information feedback, inconvenience in manual scheduling, etc. in existing industrial alarm methods, and achieve more accurate and efficient alarm management.

[0006] The technical solution of the present invention is: In a first aspect, the present invention provides an industrial alarm system based on a smart bracelet, comprising: Data acquisition module: obtains data from automation control equipment and alarm bracelet terminals in the factory through the network interface; Alarm algorithm module: analyzes the collected data, identifies the alarm tags, determines the trigger conditions and thresholds according to the alarm type, and generates corresponding alarm information; Base station management module: obtains the alarm information generated by the alarm algorithm module, locates the alarm bracelet terminal through the AOA positioning algorithm, and sends the alarm information to the corresponding Bluetooth base station; Alarm bracelet terminal: obtains the alarm information sent from the Bluetooth base station, and returns the feedback information to the alarm algorithm module through the Bluetooth base station and the base station management module.

[0007] In one example, the alarm algorithm module includes: Equipment alarm processing submodule: when receiving equipment alarm and fault information, calculate the alarm bracelet terminal corresponding to the on-duty staff associated with the equipment, and send the alarm information to the alarm bracelet terminal of the on-duty staff; Personnel safety alarm submodule: when receiving the wearer's fall or fall information sent by the alarm bracelet terminal, the wearer's fall or fall information is fed back to the alarm dispatch center, and the location information is also fed back to the alarm dispatch center; Risk alarm submodule: when receiving the alarm bracelet terminal approaching or moving away from the set danger source, it sends the risk warning alarm information to the alarm bracelet terminal; In one example, when the alarm bracelet terminal receives multiple alarm messages, it searches according to the set time sequence or alarm priority sequence.

[0008] In one example, the alarm bracelet terminal includes a microprocessor, a Bluetooth communication module electrically connected to the microprocessor, a display and touch module, a battery module, a vibration module, a sound module and an acceleration sensor, and the Bluetooth communication module is communicatively connected to a Bluetooth base station.

[0009] In a second aspect, the present invention provides an alarm method of an industrial alarm system based on a smart bracelet, comprising the following steps: S1 collects information from automation control equipment and alarm bracelet terminals in real time through the data acquisition module; S2: When the information comes from the automation control device, the information is identified as device processing information; when the information comes from the alarm bracelet terminal, the information is identified as bracelet processing information; S3: When the information is equipment processing information and is alarm and fault information, the alarm bracelet terminal corresponding to the staff on duty associated with the equipment is calculated, and the alarm information is sent to the alarm bracelet terminal of the staff on duty; S4: When the information is processed by the bracelet and is fall information, the fall information of the wearer is fed back to the alarm dispatch center, and the location information is also fed back to the alarm dispatch center; S5: When the information is processed by the wristband and is dangerous source information, the risk warning alarm information is sent to the alarm wristband terminal.

[0010] In one example, in step S5, when the alarm bracelet terminal gets closer and closer to the danger source, the vibration frequency of the alarm bracelet terminal increases.

[0011] In one example, the hazard sources include overhead cranes, belts, or other areas where human-machine motion collisions may occur.

[0012] Compared with the prior art, the present invention has the following advantages: 1. Real-time data collection and accurate alarm. The data collection module continuously obtains real-time data from the automation control equipment and the alarm bracelet terminal, providing accurate on-site information for the alarm algorithm module. By collecting equipment failure information, bracelet status and proximity to dangerous sources in real time, the system can capture alarm signals in the first place, making the alarm more accurate and timely.

[0013] 2. Intelligent alarm analysis and distribution. After receiving the information transmitted by the data acquisition module, the alarm algorithm module automatically analyzes and generates corresponding alarm information. Based on the alarm type and equipment distribution, the module dynamically identifies the priority and urgency of the alarm, thereby determining the triggering conditions and push targets of the alarm. The equipment alarm information is accurately pushed to the staff closest to the equipment. At the same time, the system can distinguish and prioritize emergency alarms to ensure the timely delivery of key information, thereby improving the intelligence and reliability of alarm management.

[0014] 3. Location-based alarm distribution. The base station management module locates the bracelet terminal through the Bluetooth base station, and obtains the wearer's precise location in combination with the AOA algorithm. When an alarm occurs, the base station management module determines the bracelet terminal closest to the alarm device based on the alarm information generated by the alarm algorithm module, and transmits the alarm information to the most suitable person. In this way, the alarm information can be accurately delivered to the relevant staff, reducing the level and delay of information transmission and ensuring the alarm response speed.

[0015] 4. Reliable alarm prompts. After receiving the alarm information from the base station management module, the alarm bracelet terminal reminds the wearer through vibration, sound, display and other methods. The bracelet terminal has a touch screen function, allowing the wearer to confirm that the alarm information has been received to avoid missed reports. In addition, when there are multiple alarm messages, the bracelet can be displayed in chronological order or priority order, allowing the wearer to reasonably arrange the alarm processing order, improving the convenience and efficiency of alarm processing. Using a smart bracelet as an alarm terminal to replace traditional voice broadcasts and alarm sounds reduces noise pollution in the workshop, effectively improves the working environment of the staff, protects their hearing health, and improves the work experience.

[0016] 5. Closed-loop feedback and information confirmation. The feedback information of the alarm bracelet terminal is transmitted to the base station management module through the Bluetooth base station, and then transmitted to the alarm algorithm module to form a closed-loop feedback mechanism. This mechanism enables the system to obtain the progress of alarm processing in real time and notify relevant personnel after the alarm is lifted, effectively solving the problem of lack of feedback in traditional alarm methods. Closed-loop feedback ensures the confirmation and tracking of alarm information, allowing staff and management systems to fully control the alarm status.

[0017] Based on the above, it can be seen that the smart bracelet industrial alarm system of the present invention realizes efficient, accurate and personalized push of alarm information, perfect management of closed-loop feedback, dynamic safety protection and efficient management process through the collaborative work of the data acquisition module, alarm algorithm module, base station management module and alarm bracelet terminal, which effectively improves the safety, management efficiency and personnel response speed of industrial workshops.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0020] Embodiment 1: An industrial alarm system based on a smart bracelet, reference Figure 1 , including data acquisition module, alarm algorithm module, base station management module and alarm bracelet terminal.

[0021] Data acquisition module: obtains data from automation control equipment and alarm bracelet terminals in the factory through the network interface; Specifically, the data acquisition module has built-in multiple industrial control protocols, such as CIP, OPC, Modbus, etc., and can read data from automation control equipment (such as PLC, DCS) and configuration software through the network interface, including field controllers, host control systems, DCS servers, and SCADA servers. The purpose of this module is to continuously obtain equipment status data, detect the operating status of the equipment, fault alarm and other information, such as controller internal alarms, host computer algorithm alarms, DCS system comprehensive alarms, SCADA system telemetry signals, position / parameters and other information, and synchronously transmit the real-time collected data to the alarm algorithm module so that the system can perform alarm analysis and push in a timely manner.

[0022] Alarm algorithm module: Analyzes the collected data, identifies the alarm tags, determines the trigger conditions and thresholds according to the alarm type, and generates corresponding alarm information. This module includes the following submodules: Equipment alarm processing submodule: When receiving equipment alarm and fault information, calculate the alarm bracelet terminal corresponding to the staff on duty associated with the equipment, and send the alarm information to the alarm bracelet terminal of the staff on duty. The equipment alarm processing submodule can send the alarm information to multiple alarm bracelet terminals or the terminal closest to the alarm location according to pre-set rules. For example, first calculate the location of the staff on duty that day associated with the equipment, and then push the alarm information to the alarm bracelet terminal closest to the equipment to ensure that the alarm information can be delivered to the appropriate staff in a timely manner.

[0023] Personnel safety alarm submodule: When receiving information about the wearer's fall or drop sent by the alarm bracelet terminal, the wearer's fall or drop information will be fed back to the alarm dispatch center, and the location information will be fed back to the alarm dispatch center. The alarm dispatch center is the current alarm system and is monitored by management personnel in the background. Furthermore, when receiving information about the wearer's fall or drop, the alarm algorithm module recognizes that the information is a personnel safety alarm and sends the fall or drop signal to other alarm bracelet terminals closest to the wearer, so that nearby staff can provide assistance. Specifically, the alarm bracelet terminal can detect the wearer's fall or drop information through the acceleration sensor and its algorithm.

[0024] Risk Alarm Submodule: When the wristband terminal detects that the wearer is close to a set danger source (such as an overhead crane or belt), the risk alarm submodule generates a risk warning message and reminds the wearer to stay away from the danger zone by vibration or beeping. When approaching a danger source, the wristband will gradually increase the vibration frequency according to the distance to remind the wearer to pay attention.

[0025] After analyzing the alarm information, the alarm algorithm module passes the alarm type, trigger condition and priority information to the base station management module to achieve accurate distribution of alarm information. The priority can be based on time or in the order of personnel safety, equipment processing and risk alarm.

[0026] Base station management module: The base station management module exchanges data with the alarm bracelet terminal through the Bluetooth base station, and combines the AOA (Angle of Arrival) positioning algorithm to perform decimeter-level positioning of the bracelet terminal.

[0027] Specifically, the AOA algorithm is used to monitor the specific location of the bracelet in real time, so that the location of each alarm bracelet terminal can be accurately determined. After receiving the alarm information generated by the alarm algorithm module, the base station management module pushes the alarm information to the staff closest to the alarm device or risk source based on the wearer's location, ensuring that the alarm information can be delivered to the most appropriate person to handle it in a timely manner. When the alarm bracelet terminal receives the alarm, the staff can confirm the receipt through the bracelet touch screen, and transmit the feedback information back to the base station management module through the Bluetooth base station, forming a closed-loop feedback mechanism. The base station management module transmits this feedback information back to the alarm algorithm module to realize the confirmation and tracking management of the alarm information.

[0028] Alarm bracelet terminal: obtains the alarm information sent from the Bluetooth base station, and returns the feedback information to the alarm algorithm module through the Bluetooth base station and the base station management module.

[0029] The alarm bracelet terminal is used as the alarm receiving device for staff. Figure 2 It has a built-in microprocessor, Bluetooth communication module, display and touch module, vibration module, sound module, acceleration sensor and battery module. The Bluetooth communication module is connected to the Bluetooth base station. The functions and operation methods of the alarm bracelet terminal are as follows: Alarm reception and reminder: The wristband terminal receives alarm information through the Bluetooth base station and reminds the wearer through vibration, sound and display. The reminder method mainly based on vibration and buzzer effectively reduces the noise pollution in the workshop.

[0030] Information display and interaction: The alarm bracelet is equipped with a touch screen, through which the staff can view the details of the alarm and confirm that the alarm information has been received. If multiple alarm messages are received, the bracelet can display them in sequence according to the priority or time sequence set by the system, helping the staff to arrange the alarm processing sequence reasonably.

[0031] Personnel fall detection and rescue: The built-in acceleration sensor of the alarm bracelet terminal can detect the wearer's fall or fall. When an abnormality occurs, the bracelet will automatically send a fall or injury signal to the alarm platform to alert nearby colleagues or management systems for rescue.

[0032] Dynamic safety reminder: When the wearer approaches a danger source (such as an overhead crane, belt, or other area where human-machine movement collision may occur), the bracelet will vibrate with changing rhythm to remind the wearer. As the distance shortens, the vibration frequency increases, helping the wearer stay alert and avoid danger.

[0033] Embodiment 2: An alarm method of an industrial alarm system based on a smart bracelet, the alarm system is as shown in Example 1, and the alarm method comprises the following steps: S1 collects information from automation control equipment and alarm bracelet terminals in real time through the data acquisition module. When equipment failure or abnormal information is identified, it immediately transmits data to the alarm algorithm module; The S2 alarm algorithm module analyzes the data to determine the alarm type and trigger conditions. When the information comes from the automation control device, it is identified as device processing information. When the information comes from the alarm bracelet terminal, it is identified as bracelet processing information. S3 When receiving equipment alarm and fault information, the system will send the alarm information to the alarm bracelet terminal of the staff on duty. The alarm submodule can send the alarm information to multiple terminals or the terminal closest to the alarm location through pre-maintained rules; S4: when the information is wristband processing information and is fall or drop information, the fall or drop information of the wearer is fed back to the alarm wristband terminal closest to the wearer of the alarm wristband terminal; S5: When the information is processed by the wristband and is dangerous source information, the risk warning alarm information is sent to the alarm wristband terminal.

[0034] The S6 wearer confirms the alarm information through the bracelet and performs the processing task. The confirmation operation is fed back to the base station management module, forming a closed-loop feedback.

[0035] The S7 alarm algorithm module records the processing progress and feedback information of each alarm, forming a historical record to facilitate subsequent statistics and analysis.

[0036] Through the above steps, the smart bracelet industrial alarm system of the present invention can realize efficient, accurate and personalized alarm information transmission and processing, greatly improving the management efficiency and personnel safety in industrial workshops.

[0037] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
