Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a fire detector simulation training device with multi-sensor monitoring function. Background Technology

[0002] Ship firefighting is a crucial component of the ship damage control system and a vital force in maintaining ship safety. The fire brigade consists of an on-site command team, a fire detection team, an isolation team, a water hose team, and an emergency pump team. Fire detection is essential for ascertaining the fire situation, fire type, fire size, and the condition of affected personnel, providing crucial information for on-site command to make firefighting decisions. Currently, ship firefighters operate on a crew rotation system, leading to significant individual differences during actual drills. Insufficient information provided by fire detectors can result in delayed or even erroneous decisions by command personnel. Furthermore, the lack of systematic training facilities and standards means that training relies solely on oral instruction from experienced firefighters, resulting in a generally low skill level among fire detectors.

[0003] Based on the above analysis, the existing technology has the following problems and defects: fire detectors are mainly crew members, and new fire detectors will be appointed during the rotation period. Due to their lack of proficiency, the entire fire-fighting process may be blocked; due to differences among personnel, individual fire detectors do not have a comprehensive grasp of the fire detection process; there is no fixed standard for measuring the training of fire detectors, resulting in huge differences during drills; fire detectors are not proficient enough in the key points of each position when detecting fire, resulting in incorrect actions during drills, which can be fatal in actual combat.

[0035] The PLC uses a Siemens S7-1200 series controller. Its digital input module SM1221 is configured to receive signals from various sensors, and its digital output module SM1222 is connected to alarm indicator lights. The PLC communicates with the host computer via the PROFINET protocol, transmitting training data to the monitoring terminal in real time. The sensor signal lines are connected to the PLC input ports via Phoenix UK5N terminal blocks.

[0042] The control board is used to install and fix system components; the fuse is used for circuit protection; and the cables used are used for connecting various parts of the system.

[0043] The terminal block is used for cable connection;

[0044] The circuit breaker is used as the power switch for the device. The 24V power module provides the 24V power required by the PLC and sensors. The alarm box is the outer frame of the alarm system, used to fix indicator lights, terminal blocks, and other components. The proximity switch sensor 1 is used to detect the movement of the fire detector's hand, the position of the door, and the position of the valve.

[0046] In summary, as Figure 1 This utility model provides a schematic diagram of the sensor position:

[0047] The proximity switch sensor 1 is used to detect the movement of the fire detector's hand, the infrared human body detection sensor 2 is used to detect whether there is anyone at the door when the door is opened, and the first position sensor 3 is used to detect the opening and closing of the door.

[0048] The sensor is fixed to the wall using silicone sealant.

[0053] The PLC collects information from various sensors and performs calculations to produce corresponding outputs.

[0054] The control board is used to mount and fix system components, such as PLCs and power modules.

[0055] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.

[0056] In summary, the training process control method includes: after power-on, the PLC executes a self-test program and verifies the response of each sensor by outputting a pulse signal through Q0.0; when training starts, the PLC resets timer T1 and enables the data recording function; when proximity switch sensor 1 detects that the fire detector's hand is close to the fire door, it triggers timer T2 to start the access control operation assessment; the system compares the standard action sequence table in real time, and when the deviation exceeds the set threshold, it drives the audible and visual alarm through Q0.5.

[0057] The system power supply architecture adopts a dual isolation design: the primary side AC220V is converted to AC24V via isolation transformer TN1, and the secondary side generates DC24V through rectifier module RM1. Critical signal lines use twisted-pair shielded cables, with the shielding layer grounded at a single point to the PE terminal block. The PLC analog input channels are equipped with RC filter circuits, with a cutoff frequency set to 10Hz to eliminate mechanical vibration interference.

[0058] The system maintenance interface is located at the bottom of the alarm box and includes: a USB programming port, an SD card data export slot, and an RS485 debugging interface. In maintenance mode, training parameters can be set via the HMI panel, including: standard action time threshold setting range (0.5-5.0 seconds), maximum allowed number of errors (1-5 times), alarm duration (3-30 seconds), and other adjustable parameters. The system log recording function can store the most recent 1000 training data sets, including timestamps, sensor status matrices, and evaluation results.

[0059] Typical training scenario implementation example: When a fire detector enters the simulated chamber, the laser beam sensor group detects the walking posture. If the operator walks upright for more than 3 seconds, the Q0.2 alarm is triggered. Proximity switch sensor 1 detects the operating force of the fire door handle; if the pressure value is less than 2N, the operation is considered invalid. Microswitch sensor 6 monitors the dummy's rescue actions; continuous pressing for more than 3 seconds is required for a valid rescue. All operational data is displayed in real time on the LED screen of the alarm box. After the training is completed, an evaluation report containing 12 scoring elements is automatically generated.
