[0003] Smoke alarms prevent fires by monitoring the concentration of smoke. Smoke alarms can detect smoke generated in the early stages of a fire and send out an alarm signal when the smoke concentration reaches the alarm threshold. Sensitivity is an important technical indicator of smoke alarms, and the quality of smoke alarms is directly determined by the sensitivity of the smoke alarm. When smoke alarm manufacturers produce smoke alarms, it is necessary to test the sensitivity of each smoke alarm.

Due to individual differences in photoelectric sending and receiving tubes and optical mazes, smoke alarm products need to be calibrated on a single chip to ensure that the sensitivity meets the specifications.

[0120] Figure 4b A geometric structure diagram of a physical cigarette box provided in an embodiment of the present application. Figure 4c A schematic diagram of the structure of a twin cigarette box provided in an embodiment of the present application. Figure 4b and Figure 4c The twin smoke box includes: geometric model (G v ), physical model (P v ), behavioral model (B v ) and rule model (R v ), the virtual model describes and characterizes the physical entity from multiple time scales and multiple space scales, and its mathematical expression is shown in (1).

[0121] VE=(G v , P v , B v , R v ) (1)

[0122] When building a twin smoke box, the first thing to do is to map the physical smoke box's size, shape, assembly relationship and other attributes and rules, so that the twin smoke box can simulate the geometry, constraints and physical properties of the real physical smoke box through known experience or physical laws. Secondly, the production behavior of the physical smoke box is expressed in the model, mainly describing the multi-disciplinary, multi-physical quantity, and multi-scale data information such as mechanical data, electrical data, control data, process data, and state data associated with the behavior activities. Finally, by collecting the physical smoke box production data and comparing it with the virtual simulation data, decisions are made based on the relationship and rules between the parameters, and feedback is given to the real physical smoke box to realize the monitoring of the physical smoke box production process.

[0123] Secondly, the geometric model is a three-dimensional model that describes the shape, size, position and assembly relationship of the entity, and has good temporal and spatial consistency with the physical entity. In order to achieve the motion effect during the calibration of the smoke box, each component must be established according to the assembly relationship. A complete physical smoke box usually consists of a smoke box body, moving parts, control system, electrical subsystem, heating device, smoke generating device, speed measuring device, and auxiliary structures such as pneumatic subsystem and smoke exhaust system. In order to improve the efficiency of computer graphics processing and simulation, the three-dimensional model needs to be lightweight during modeling, retaining key components such as the smoke box body, work platform, smoke generating device, heating device, alarm, etc.; simplifying components that have no obvious relationship with the simulation, such as air pressure device, control system, smoke exhaust device, etc., only needs to show the complete external dimensions and accurate motion form of the physical smoke box, and ignore the remaining auxiliary structures.

[0124] Constructing the geometric model G v The mathematical expression of is (2):

[0125] G v =(S g ,D g ,P g ,AR g ,PR g ) (2)

[0126] Where: S g is the geometric shape, D g is the geometric size, P g is the geometric position, AR g is the assembly relationship, PR g For position relationship.

[0127] Thirdly, the physical model adds the physical properties of the physical smoke box and physical products (such as smoke alarms) to the geometric model. For example, the thermal, mechanical, and optical properties of the smoke generating device, speed measuring device, and temperature measuring device are added to the model to realize the physical characteristics of the equipment. By adding sensors to collect the real-time motion state of the product and the environmental parameters of the smoke box, the physical model of the smoke box is constructed. The physical model of the smoke box P v The mathematical expression is (3):

[0128] P v =(E p ,Y p ,PC,EP,Info) (3)

[0129] In the formula, E p is the physical property of the smoke box, Y p is the physical property of the alarm, PC is the physical property of the smoke box, such as length, width, and height expressing the cross-sectional area through the space, EP is the environmental parameter of the smoke box, and Info is other information.

[0130] Among them, E p The physical properties of the smoke box include the model T of the smoke box e , smoke box running speed V e , the power of the smoke box is O e , light speed wavelength L e , optical measurement length d, radiation power P0 received when there is no smoke, radiation power P received when there is smoke, etc. Its mathematical expression is (4):

[0131] E p =(T e ,V e , O e ,d,P0,P...) (4)

[0132] Y p The physical properties of the smoke alarm as a product include the model T of the smoke alarm y , State S y , working voltage V dc , static current QC, alarm current AC, alarm sound pressure ASP, sensitivity SS, etc. Its mathematical expression is (5):

[0133] Y p =(T y , S y , V dc ,QC,AC,ASP,SS..) (5)

[0134] EP smoke box environmental parameters include the temperature T in the smoke box ep 、Humidityep , air pressure p ep , wind speed W ep , smoke density D ep , Smoke frequency F ep , shielding rate C ep Etc. Its mathematical expression is (6):

[0135] EP=(T ep ,H ep ,p ep , W ep ,D ep ,F ep ,C ep ...) (6)

[0136] Virtual simulation debugging relies on model construction at the sensor and actuator levels. The behavioral models in the twin smoke box are divided into sensor modeling and actuator modeling. According to the requirements of the calibration environment parameters, the corresponding sensors of the smoke box (such as temperature and humidity sensors, flow rate sensors, smoke concentration sensors, etc.) are defined according to the working principle of the sensor. Through sensor behavior modeling, the signal generated by the digital model based on the working conditions is fed back to the control system. In order to increase the accuracy of the timing of triggering the calibration and avoid the error caused by triggering the calibration only by calculating that the smoke box environmental parameters meet the standards, sensors are set at each product entrance. The calibration timing of the smoke box is determined by distance calculation and sensor triggering, thereby improving the success rate of calibration.

[0137] Based on the working principle of the driven smoke box, the motion control parameters of the corresponding actuators are defined, and the interaction signals of the control system are associated with the motion properties of the digital model. With the help of actuator behavior modeling, the digital model can realize the actuator movement driven by the output signal of the control system.

[0138] As a behavioral model B v Including process parameter set P ps , process sequence set P ss , smoke box operation data set R d , alarm operation data set Y rd , smoke box environment parameter set EP and other information Info are obtained through the data interface set and rendered on the model. v The mathematical language is expressed as formula (7):

[0139] B v =(P ps ,P ss ,R d ,Y rd ,EP,Info...) (7)

[0140] The design of the rule model needs to be carried out on the basis of the behavior model. In order to establish the rule model of the model and make the model meet the requirements of virtual commissioning, it is necessary to implement the control logic based on PLC control to meet the system requirements.

[0141] Combination Figure 4b and Figure 4c According to the external dimension data of the physical smoke box, the names of important components (e.g. display, work platform), location data, and operation data, digital twin simulation is performed to generate Figure 4c The twin smoke box is simulated based on the functional sensor.

[0144] The embodiment of the present application is applied to the digital twin smoke box system for calibration and monitoring of smoke alarms during the production process. By designing the overall framework of the digital twin smoke box system, a digital twin five-dimensional model of the physical smoke box is constructed using the target platform (such as Siemens NX platform, solidwork platform or 3DS Max platform), and a virtual-real communication platform is built using the OPCUA communication protocol. Data is collected from the physical smoke box and the twin smoke box through PLC, sensors, RFID, etc., and real-time mapping between the physical smoke box and the twin smoke box is achieved, so as to achieve calibration and monitoring during the production process of the smoke alarm, improve the efficiency and quality of calibration, and provide new ideas for the digital production of smoke alarms.

The five-dimensional model mentioned here can be understood as a model for realizing the twin control between the physical smoke box and the twin smoke box. The communication connection mentioned here can be understood as the connection for realizing the twin control between the physical smoke box and the twin smoke box.

[0150] S503: Map the target monitoring data and the twin data according to a pre-set calibration rule to obtain a mapping result.

[0151] The calibration rules mentioned here can be understood as the calibration data set for the calibration product. The mapping mentioned here can be understood as the result of different processing of data through different algorithm formulas.

[0152] Furthermore, by pre-setting the calibration rules for the product to be calibrated, and then using the obtained target monitoring data and twin data for algorithm mapping processing, it is determined whether the mapping results of the two types of data are consistent. Consistency indicates that the twin is successful and the product calibration is successful; inconsistency indicates that the twin fails and the calibration fails.

[0153] S504. Determine the calibration result of the digital twin smoke box system based on the mapping result.

[0154] The calibration result mentioned here can be understood as the result of successful calibration or failed calibration.

[0155] Furthermore, based on the mapping results, it is determined whether the physical data of the physical cigarette box and the physical product in the physical layer are consistent with the data of the twin cigarette box and the twin product in the twin layer. If they are consistent, it means that the product calibration is successful. If they are inconsistent, it means that the product calibration has failed, thereby achieving the process of product calibration through digital twin technology.
