Description

Technical Field

[0001] This utility model relates to refrigerated trucks, specifically providing a cold compartment monitoring system and a refrigerated truck. Background Technology

[0002] In refrigerated trucks, cold storage facilities, and other low-temperature cold rooms, the stringent requirements for insulation performance necessitate the use of heavy-duty, well-sealed doors. On one hand, to effectively prevent cold air leakage, traditional cold rooms often lack sound transmission devices such as vents or intercom systems. This means that when people inside encounter an emergency and attempt to call for help, their voices are difficult to penetrate the heavy door and reach the outside, significantly reducing the likelihood of timely detection of the anomaly by outsiders. On the other hand, some cold rooms, for safety or structural simplification, lack internally operable door locks. This makes it difficult for people to escape if they accidentally enter and the door closes and locks, easily leading to entrapment and potentially causing serious accidents such as asphyxiation, frostbite, hypothermia, or even death.

[0003] Currently, existing technologies for ensuring the safety of cold storage rooms primarily rely on external control, such as electronic access control systems and remote unlocking modules. While these offer some management convenience, they lack a timely and effective response mechanism for sudden entrapment situations within the cold storage room. Especially given the consistently low temperatures inside cold storage rooms, the stability and response speed of conventional electronic components are limited. Furthermore, the physiological functions of trapped individuals may decline due to the low temperatures, making it difficult for them to actively send out distress signals, further increasing the difficulty and risk of rescue.

[0004] Therefore, there is an urgent need in this field for a cold room monitoring system and a refrigerated truck to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that trapped personnel in existing cold rooms cannot escape on their own.

[0006] In a first aspect, the present invention provides a cold room monitoring system, the cold room including a door and a door lock, the door lock including an inner unlocking part to allow the door lock to be opened from inside the cold room, the cold room monitoring system comprising:

[0007] A temperature sensing element is used to monitor whether a heat source exists in the cold chamber;

[0008] A prompting component, disposed within the cold room, is used to prompt personnel within the cold room to open the door lock via the inner unlocking part;

[0009] The control module is electrically connected to both the temperature sensor and the alerting component. The control module can control the state of the temperature sensor according to the state of the door, and can also control the state of the alerting component according to the detection result of the temperature sensor.

[0010] In a specific implementation of the above-mentioned cold room monitoring system, the prompting component includes a voice prompting element, which is used to play a prompting voice.

[0011] In a specific embodiment of the above-mentioned cold room monitoring system, the prompting component includes an indicator light, which is located at the inner unlocking part.

[0012] In a specific embodiment of the above-mentioned cold room monitoring system, the cold room monitoring system further includes a door detection component, which is capable of monitoring the status of the door and is electrically connected to the control module.

[0013] In a specific embodiment of the above-mentioned cold room monitoring system, the cold room monitoring system further includes a monitoring terminal set outside the cold room, the control module being signal-connected to the monitoring terminal, and the control module being able to send information to the monitoring terminal.

[0014] In a specific embodiment of the above-mentioned cold room monitoring system, the cold room monitoring system further includes a thermal imaging device, which is capable of acquiring thermal imaging images inside the cold room. The thermal imaging device is electrically connected to the control module, and the control module is capable of sending the thermal imaging images acquired by the thermal imaging device to the monitoring terminal.

[0015] In a specific embodiment of the above-mentioned cold room monitoring system, the cold room monitoring system further includes a trigger installed inside the cold room. The trigger is electrically connected to the control module. When the trigger is activated, the control module can send alarm information to the monitoring terminal.

[0016] In a specific implementation of the above-mentioned cold room monitoring system, the monitoring terminal includes an alarm device. When the monitoring terminal receives an alarm message, the alarm device can emit a prompt sound.

[0017] In a specific embodiment of the above-mentioned cold room monitoring system, the cold room monitoring system further includes a first communication component and a second communication component. The first communication component is disposed inside the cold room, and the second communication component is disposed outside the cold room. The first communication component and the second communication component are signal connected.

[0018] In a second aspect, the present invention provides a refrigerated truck that includes the aforementioned cold compartment monitoring system.

[0019] By adopting the above technical solution, this utility model can effectively solve the technical problem that trapped personnel in existing cold rooms cannot escape on their own. By setting an internal unlocking mechanism in the door lock, combined with a temperature sensor to monitor the presence of heat sources inside the cold room in real time, and with the control module controlling a prompting component to issue a prompt, the trapped personnel can operate the internal unlocking mechanism, thereby enabling them to independently open the door lock from inside the cold room. This effectively improves the safety of cold room use and reduces the risk of personnel being trapped.

[0020] Furthermore, the prompting components include a voice prompt and an indicator light located at the door lock, enhancing the perceptibility and guidance effect of the prompting components. The voice prompt plays a prompt message, guiding trapped personnel to unlock the door in an emergency; while the indicator light at the door lock clearly indicates the unlocking location visually, facilitating quick identification and operation, thereby improving escape efficiency and further enhancing safety during cold room use.

[0021] Furthermore, by setting up a monitoring terminal located outside the cold room in the cold room monitoring system and connecting the control module to the monitoring terminal, real-time remote monitoring of the cold room's status can be achieved. This configuration enables managers to promptly receive abnormal information and personnel status within the cold room, quickly respond to emergencies, significantly improve the cold room's safety management level and emergency response capabilities, and ensure personnel safety.

[0022] Furthermore, to address the special circumstances where there may be underage children or small animals inside the cold storage facility who cannot unlock the doors themselves using the alert system, thermal imaging devices are used to capture real-time thermal images of the cold storage interior and upload them to the monitoring terminal. This alerts staff at the monitoring terminal to any abnormal situations within the cold storage. Staff can accurately assess the condition of any trapped individuals or animals based on the thermal images and quickly take rescue measures, effectively compensating for the shortcomings of this system and significantly improving the comprehensiveness of cold storage safety monitoring and emergency response capabilities.

[0033] To address the problem of people trapped inside existing cold storage compartments being unable to escape on their own, this embodiment discloses a refrigerated truck. The refrigerated truck includes a cold storage compartment and a cold storage compartment monitoring system.

[0034] Reference Figure 1 The cold chamber 11 includes a door 12 and a door lock 13. The door 12 can close or open the cold chamber 11, and the door lock 13 can lock the door 12 when the cold chamber 11 is closed. Furthermore, the door lock 13 includes an inner unlocking part 131, through which personnel inside the cold chamber 11 can unlock the door lock 13. The structure of the inner unlocking part 131 of the door lock 13 is the same as that of the door lock 13 in the prior art, and its specific structure will not be described in detail here.

[0035] Reference Figure 2 The cold room monitoring system includes a door detection component 25, a temperature detection component 21, an alert component, a monitoring terminal 26, a thermal imaging component 27, and a control module 22.

[0036] The door detection element 25 is used to detect the state of the door 12. Specifically, the door detection element 25 is a limit switch. When the door 12 is closed, the limit switch is triggered to send a corresponding electrical signal.

[0037] The temperature sensor 21 is used to detect the presence of a heat source within the cold chamber 11. The presence of a heat source indicates the possible presence of personnel or other living organisms within the cold chamber 11. In this embodiment, the temperature sensor 21 is specifically an infrared pyroelectric sensor. In other embodiments, other devices may be used for the temperature sensor 21.

[0038] The prompting component is used to guide personnel trapped inside the cold compartment 11, assisting them in opening the door lock 13 via the internal unlocking part 131 to achieve self-rescue. The prompting component includes a voice prompt 23 and an indicator light 24. The voice prompt 23 can play voice prompts, promptly reminding trapped personnel to open the door lock 13 via the internal unlocking part 131, providing excellent emergency response capabilities. The indicator light 24 is located near the internal unlocking part 131 of the door lock 13, clearly marking its location visually, facilitating quick identification and operation by trapped personnel, thereby improving rescue efficiency and further enhancing safety during the use of the cold compartment 11.

[0039] The monitoring terminal 26 is located outside the cold compartment 11, allowing monitoring personnel to obtain information about the interior of the cold compartment 11 from outside. This setup helps management personnel quickly grasp abnormal information within the cold compartment and take emergency measures, significantly improving the safety management level and emergency response capabilities of the cold compartment, thereby effectively protecting personnel safety. The monitoring terminal 26 includes an alarm device; when a person trapped inside the cold compartment 11 is unable to escape, the alarm device is activated, emitting an alarm sound or illuminating a light to alert the monitoring personnel.

[0040] The thermal imaging device 27 is specifically a thermal imager, which can generate thermal images of the cold chamber 11. The monitoring terminal 26 can also be equipped with a display screen to show the thermal images generated by the thermal imaging device 27, so that monitoring personnel can judge the situation inside the cold chamber 11.

[0041] Door detection component 25, temperature detection component 21, alerting component, monitoring terminal 26, and thermal imaging component 27 are all electrically connected to control module 22. Control module 22 is configured to execute the control method of the cold room monitoring system. (Refer to...) Figure 3 The control method includes the following steps:

[0042] S1, the door detection component 25 detects the status of the door 12. When the door 12 is closed, S2 is executed. When the door 12 is not closed, S1 is executed again.

[0043] S2, temperature sensing device 21 detects whether there is a heat source in cold chamber 11. When there is a heat source in cold chamber 11, S3 is executed. When there is no heat source in cold chamber 11, S2 is executed again.

[0044] S3: Activate the prompt component to remind personnel inside cold room 11 to unlock door 13. Execute S4 after a preset time.

[0045] S4, temperature sensing device 21 detects whether there is a heat source in cold chamber 11. If there is a heat source in cold chamber 11, execute S5. If there is no heat source in cold chamber 11, execute S2 again.

[0046] S5, activate thermal imaging device 27 to generate a thermal image of the cold chamber 11. Then execute S6.

[0047] S6 sends the thermal image to the monitoring terminal 26.

[0048] After the door 12 of the cold compartment 11 is closed, the control method activates the temperature sensor 21 to detect the presence of a heat source inside the cold compartment 11. If a heat source is present, it indicates that someone may be trapped inside. The system then activates a prompting component to guide the trapped person to operate the internal unlocking mechanism 131 to unlock the door 13, allowing them to escape safely from the cold compartment 11. This significantly improves the safety of the cold compartment 11 during use and reduces the risk of people being trapped. After a preset time, the system checks the cold compartment 11 again for heat sources. If a heat source is present, it indicates that the trapped person cannot escape on their own or that other abnormalities have occurred. At this time, the thermal imaging component 27 generates a thermal image of the cold compartment 11 and sends it to the monitoring terminal 26. This image allows monitoring personnel to accurately determine whether there are trapped people or animals inside the cold storage and their condition, enabling them to quickly take appropriate rescue measures. This design effectively overcomes the limitations of prompting and guidance methods, significantly improving the comprehensiveness and emergency response capabilities of the cold compartment 11 safety monitoring system, and further ensuring the safety of people and animals.

[0049] The control module 22 is configured to execute the control method of the above-mentioned cold compartment monitoring system. The control module 22 can be configured to execute only the control method and not execute other operation controls of the refrigerated vehicle. Other operation controls can be equipped with other control modules 22. Alternatively, it can be configured to execute other operation controls of the refrigerated vehicle in addition to executing the control method. That is, the control module 22 is a comprehensive execution module that executes various programs in the refrigerated vehicle.

[0050] Furthermore, the cold room monitoring system also includes a trigger, specifically an alarm button. A person trapped inside the cold room 11 can trigger the alarm button to activate the alarm device on the monitoring terminal 26, alerting the monitoring personnel. In other embodiments, an alarm device can also be installed outside the cold room 11. When a trapped person triggers the alarm button, the alarm device outside the cold room 11 is activated, reminding nearby personnel to open the door 12 to help the trapped person escape in time.

[0051] Furthermore, the cold chamber monitoring system also includes a first communication device and a second communication device. The first communication device is located inside the cold chamber 11, and the second communication device is located outside the cold chamber 11 or at the monitoring terminal 26. Personnel trapped inside the cold chamber 11 can communicate with personnel outside the cold chamber 11 through the first communication device to facilitate timely escape.

[0052] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
