Description

Technical Field

[0001] This utility model relates to the field of early warning technology, and in particular to a computer room monitoring and early warning system. Background Technology

[0002] With the rapid development of information technology, the number and scale of infrastructure such as data centers and computer rooms are constantly increasing. These facilities centrally deploy a large number of computing and network devices, undertaking important computing and data storage tasks. Computer rooms are characterized by numerous devices, limited space, and complex environments, often facing challenges from harsh environmental factors such as high temperatures and humidity. Therefore, the security of computer rooms, especially fire safety, has become particularly important. Currently, traditional computer room fire monitoring systems typically rely on temperature monitoring or smoke concentration monitoring for early warning. However, these traditional systems have certain shortcomings in terms of early warning accuracy and response speed in the early stages of a fire. Single temperature or smoke monitoring may lead to failure to identify early fires in a timely manner, or false alarms due to large temperature fluctuations. At the same time, many existing systems do not fully consider alarm methods under different fire scenarios, easily resulting in single warning signals and slow responses, thus affecting personnel reaction time and safety. To improve the accuracy and response speed of fire early warning systems, modern fire monitoring systems are gradually adopting multiple monitoring methods and multiple threshold settings. For example, combining temperature and smoke concentration signal monitoring can provide more accurate early warning information at different stages of a fire. In addition, the diversity of alarm signals enables different warning methods (such as sound, light signals or vibration) to be output in a timely manner according to the severity of fire information in different emergency situations, so that staff can identify fire risks more quickly and accurately and make timely responses.

[0003] The patent “A computer room environment early warning system” (publication number CN221828970U, hereinafter referred to as prior art 1) discloses a monitoring and early warning device. The technical principle of prior art 1 is to realize real-time monitoring and early warning of the computer room environment by setting a first electric slide rail, a second electric slide rail, a first pulley, a smoke detector and a second pulley, as well as a limit plate, a lock and an unlocking block, so as to detect fires in time and protect the lives of staff.

[0004] While existing technology 1 can monitor and issue warnings in real time using smoke detectors, it still has certain shortcomings in complex computer room environments. False alarms or missed alarms may still occur when environmental changes are significant or smoke concentration fluctuations are frequent. For example, certain non-fire events (such as heat or smoke generated by equipment operation) may trigger alarms, but the sensors may fail to detect changes in time when a real fire occurs. Furthermore, during equipment cleanup, the actual sensitivity of the sensors and the weak signals in the early stages of a fire may not be fully considered, potentially leading to an untimely fire monitoring response. Therefore, existing technology 1 still carries the risk of false alarms and missed alarms in highly complex environments. Utility Model Content

[0016] The computer room monitoring and early warning system provided by this utility model has the following beneficial effects:

[0017] Because the system has multiple internal chambers and detectors, and the detection apertures are designed in a spaced-around pattern, it reduces interference from the external environment and enhances the system's ability to perceive changes in the actual environment of the computer room. Especially in complex environments like computer rooms, the system's redundant design (such as the inclusion of a second chamber and multiple detectors) effectively prevents false alarms and missed alarms. The connectivity between the controller and the alarms ensures a rapid triggering of alerts when an anomaly is detected, improving the real-time performance of the early warning system, reducing response delays, and enhancing system effectiveness.

[0028] Example 1

[0029] Please see Figure 1 This utility model embodiment provides a monitoring and early warning system for a computer room 100. Since computer rooms 100 typically house numerous IT cabinets containing a large number of operating electronic devices, these devices generate heat during operation. Although the IT cabinets are typically equipped with cooling devices or air conditioners for heat dissipation, overheating and potential fires due to aging or prolonged use can still occur. To ensure the safety of the computer room 100 environment, this embodiment employs a combined temperature and smoke warning device 200 to safeguard the safety of the computer room 100. This device provides an alarm or warning system when potential problems arise in the computer room 100 environment, allowing staff to conduct timely safety checks.

[0030] In real-world applications, data center 100 typically houses a large number of devices, whose normal operation is crucial for the stability and reliability of the entire system. However, relying on manual monitoring is not only time-consuming and labor-intensive, but also makes it difficult to achieve comprehensive monitoring of all devices. Human monitoring can also lead to the omission of critical information due to negligence or fatigue, thus failing to detect potential problems in a timely manner. Therefore, to ensure the safe and stable operation of data center 100, introducing a data center 100 monitoring and early warning system is particularly necessary. This system can monitor data center 100 24 / 7, promptly detecting and issuing warnings for any abnormal situations that may affect the safe operation of data center 100, thereby ensuring the safe use of data center 100.

[0031] In this embodiment, the monitoring and early warning system for the computer room 100 is a fully automated monitoring system. It includes an early warning device 200, which monitors the environmental information within the computer room 100 in real time. This environmental information covers various key parameters such as temperature, humidity, and smoke. The early warning device 200 collects the necessary information, and by continuously collecting and analyzing this environmental data, the system can promptly detect any indicators deviating from the normal range and activate early warning or alarm mechanisms. This setup not only improves the comprehensiveness and accuracy of monitoring but also significantly reduces the workload of manual monitoring, ensuring the stability of the computer room 100 environment and the safe operation of the equipment.

[0032] Please see Figure 2 and Figure 3 The warning device 200 consists of a housing 210 and a cover 220 connected to the housing 210; the housing 210 and the cover 220 together constitute the outer shell structure of the warning device 200. This arrangement not only ensures the integrity of the device, but also provides necessary protection for the internal working components and circuits.

[0033] Inside the housing 210, a hollow receiving cavity is provided, which is divided into two adjacent chambers, namely the first chamber 211 and the second chamber 212, which are used to accommodate and house different key components of the computer room 100 monitoring and early warning system.

[0034] Please see Figure 4 In this embodiment, the early warning device 200 includes a controller 310 and multiple detectors 320; these detectors 320 are divided into a first detector and a second detector. The first and second detectors are each responsible for monitoring different environmental parameters or information. For example, the first detector may be specifically used to detect temperature, while the second detector may be specifically used to detect smoke concentration. The controller 310 coordinates and manages the workflow of the entire early warning system, including but not limited to activating the alarm mechanism, issuing early warning signals, and other necessary control commands.

[0035] Please see Figure 3 and Figure 4 The controller 310 and detector 320 are installed inside the early warning device 200, specifically within the space of the first chamber 211. Meanwhile, the second chamber 212 contains a power supply unit 330 and an alarm. The power supply unit 330 provides stable power to the entire early warning device 200, while the alarm issues a warning or alarm signal when an abnormality is detected, alerting personnel to conduct troubleshooting. Furthermore, the cover 220 has a plurality of evenly distributed, circumferentially spaced detection holes 221 on its sides. The cover 220 can be easily installed on the top of the machine room 100. Since gases such as smoke typically rise and accumulate on the top of the machine room 100 after generation, the detection holes 221 on the top can effectively capture these gases. When gas enters the housing 210 through the detection holes 221, the first or second detector can promptly detect its presence and determine whether to trigger a warning or alarm signal based on its concentration.

[0036] The warning device 200 has a warning hole 213 at the bottom of its housing 210, which communicates with the internal receiving cavity. This ensures that when a warning or alarm signal is triggered, the sound or vibration of the warning or alarm can be smoothly transmitted from the receiving cavity to the ears of the personnel, thereby effectively notifying them to take appropriate measures. This design avoids the sound or vibration signal being confined within the receiving cavity, thus preventing it from affecting the sound propagation effect and clarity.

[0037] To further ensure the effective transmission of sound or vibration signals, the alarm is connected to the controller 310 and placed inside the receiving cavity corresponding to the warning hole 213. This arrangement allows sound or vibration signals to be transmitted directly from the alarm to the warning hole 213 and then to the external environment, ensuring that staff can clearly receive the warning or alert signals and react promptly to avoid potential safety risks.

[0038] The alarm is disc-shaped and is installed flush against the bottom surface inside the housing 210. The sound output part of the alarm is aligned with the warning hole 213, allowing the alarm or warning sound to be transmitted through the bracket without being blocked inside the housing 210, thus preventing the volume from being reduced. Furthermore, the alarm is located on one side of the controller 310, facilitating wiring arrangement.

[0039] In this embodiment, the collection of fire information covers at least two key parameters: temperature signal and smoke concentration signal. The first detector and the second detector are configured as a temperature sensor and a smoke sensor, respectively, and their main function is to acquire relevant information in the environment. The temperature signal and smoke concentration signal detected by these sensors are then transmitted to the controller 310.

[0040] The smoke sensor is cylindrical with a protruding portion to increase its surface area and the space for smoke to enter. Several smoke entry holes are also provided on the side of the smoke sensor, and the sensor's height is approximately equal to the height of the internal cavity of the housing 210. This allows smoke to enter the cavity through the detection hole 221 of the top cover 220, directly into the interior of the smoke sensor, making smoke easier to detect and improving the accuracy of smoke concentration determination.

[0041] Specifically, fire information includes two key parameters: temperature signal and smoke concentration signal. To accurately acquire this information, the early warning device 200 is equipped with corresponding sensors that monitor temperature and smoke concentration in real time. Once a change in temperature or smoke concentration is detected, the sensors convert these changes into corresponding electrical signals and output these signals for further processing and analysis by the controller 310.

[0042] Further, please see Figure 4 The early warning device 200 involved in this embodiment includes a sound alarm unit 230, the main function of which is to issue a first warning signal or a second warning signal; and a vibration prompting unit, which works in conjunction with the sound alarm unit 230 to issue a second warning signal by vibration.

[0043] With this configuration, the warning device 200 can deliver warning information to the user in multiple ways. Specifically, the sound alarm unit 230 conveys a first or second warning signal through auditory signals, while the vibration alert unit enhances the transmission of the second warning signal through tactile signals. In situations with high ambient noise or where sound signals may be ignored, vibration signals can serve as an effective supplementary means. This combination of sound and vibration in the warning system not only improves the perceptibility of the warning signals but also enhances the distinguishability between different warning signals. Therefore, this design significantly improves the reliability of the warning system and the user's response efficiency.

[0044] The environmental information includes fire information; the controller 310 is used to control the alarm to trigger a corresponding warning signal according to a threshold of the fire information; the controller 310 is connected to both the detector 320 and the alarm; wherein, the controller 310 is also used to receive fire alarm information output by the detector 320. When the fire alarm information matches a first threshold, the controller 310 controls the alarm to output a first warning signal; when the fire alarm information matches a second threshold, the controller 310 controls the alarm to output a second warning signal; and the first warning signal and the second warning signal have different prompting methods.

[0045] In this embodiment, the controller 310 controls the alarm based on fire information thresholds, causing it to trigger a corresponding alarm signal when specific conditions are met. Specifically, these thresholds include two main levels: a first threshold and a second threshold. The first threshold includes a first smoke threshold and a first temperature threshold; while the second threshold includes a second smoke threshold and a second temperature threshold.

[0046] Under normal operating conditions, when the temperature or smoke concentration detected by detector 320 is below the first temperature threshold or the first smoke threshold, this indicates that the temperature or smoke concentration inside computer room 100 is at a normal or safe level. In this case, it can be considered that there is no possibility or indication of a fire in computer room 100, and therefore, it is not necessary to activate the alarm mechanism.

[0047] However, when the temperature or smoke concentration detected by detector 320 is between the first temperature threshold and the second temperature threshold, or between the first smoke threshold and the second smoke threshold, this indicates that the temperature and smoke concentration inside server room 100 have deviated from normal conditions and are in a potentially unsafe state. In this situation, the alarm will sound an audible warning to alert staff to the abnormal state of server room 100. Staff need to inspect server room 100 to identify the source of the hazard and take necessary measures, such as immediately cutting off the power, to prevent potential dangers from occurring.

[0048] If the temperature or smoke concentration detected by detector 320 exceeds the second temperature threshold or the second smoke threshold, it means that the temperature and smoke concentration inside computer room 100 have exceeded the safe range and may be in a dangerous state. In this emergency, the alarm can be triggered immediately by connecting the smoke sensor or temperature sensor to the warning device to ensure timely action and prevent possible fires or other dangerous events.

[0049] Furthermore, the controller 310 also has the function of receiving fire alarm information output from the information detector 320; once the detected fire alarm information matches a preset first threshold, the controller 310 will trigger the alarm to issue a first warning signal; correspondingly, when the fire alarm information matches a second threshold, the controller 310 will instruct the alarm to issue a second warning signal. These two warning signals differ in their prompting methods. Through this setting, fire alarm information can be matched with different thresholds, thereby realizing a graded response mechanism for fire early warning. Specifically, the first warning signal is used to indicate low-level fire risks, reminding staff to conduct timely inspections, while the second warning signal is used to indicate high-level fire risks, prompting relevant personnel to take rapid emergency response measures. This design of different prompting methods can clearly distinguish the fire level, avoid information confusion, and thus improve the targeting and processing efficiency of the early warning. At the same time, it also reduces the possibility of unnecessary interference and misoperation, thereby enhancing the practicality and reliability of the system.

[0050] Please see Figure 2 In this embodiment, the early warning device 200 also includes a status indicator light 214, which is connected to the controller 310. The main function of the status indicator light 214 is to display the current operating status of the early warning device 200 in the computer room 100 to the user; specifically, this operating status covers at least two situations: normal operation and fault operation. With this configuration, the status indicator light 214 can intuitively display the operating status of the early warning device 200. In normal operation, the indicator light will illuminate, indicating that the device is functioning properly. Conversely, in a faulty operating state, the indicator light will emit an abnormal signal, such as by flashing or changing color, to attract attention. This rapid visual feedback mechanism can quickly alert staff that the equipment may require maintenance or repair. This configuration greatly simplifies the monitoring process of the equipment status, enabling staff to promptly identify and address problems, thereby preventing fire early warning failures due to equipment malfunctions. This not only improves the safety and reliability of the entire system but also reduces the frequency of manual inspections and corresponding maintenance costs.

[0051] The status indicator light 214 is designed to protrude outward from the inside of the housing 210 and is located on the outside of the housing 210. This design allows staff to more easily observe the status of the equipment. The purpose of this design is to prevent staff from being unable to promptly detect abnormal conditions in the event of a fire if the warning device 200 is damaged. This avoids the possibility of being unable to immediately initiate rescue operations due to the inability to observe warning signals in time, which could lead to more serious property damage and casualties.

[0052] The power supply unit 330 of the early warning device 200 includes a rechargeable battery and a power supply interface. This design allows the early warning device 200 to obtain a stable power supply through the power supply interface when the mains power supply is normal, while simultaneously charging the built-in rechargeable battery. In the event of a power outage, the built-in rechargeable battery can quickly switch to power, ensuring the device's continuous operation is unaffected. This configuration greatly improves the reliability of the early warning device 200, effectively avoiding the problem of early warning function failure due to power outages. Therefore, it ensures the continuity and reliability of the computer room 100 monitoring system. Especially in emergencies, the early warning device 200 can continuously provide early warning signals, thereby significantly improving the device's safety assurance capabilities in critical scenarios and ensuring the safety of personnel and equipment.

[0053] In fire early warning systems, the initial warning sound is designed as a continuous low-frequency tone. This sound is characterized by its low frequency and steady rhythm, providing a stable and non-harsh alert. This sound design aims to issue a preliminary warning signal when the fire alarm reaches the first threshold, allowing for timely initial response measures.

[0054] Meanwhile, the second warning signal's audible tone is designed as an intermittent high-frequency sound. This sound, characterized by its high frequency and intermittent rhythm, creates a more urgent and attention-grabbing warning effect. The purpose of this sound is to signal an emergency when the fire alarm information reaches the second threshold, prompting people to take more urgent and effective countermeasures to deal with a more severe fire.

[0055] This differentiated audible alert setting not only helps users quickly distinguish the severity level of a fire, but also prompts personnel to take appropriate response measures based on different fire levels. This setup not only improves the practicality and safety of the early warning system, but also enhances people's reaction speed and handling capabilities in emergency situations through clear audible signals, thereby minimizing casualties and property damage during a fire.

[0056] In this embodiment, several early warning devices 200 are installed on the top of the computer room 100. This fully utilizes the physical characteristics of smoke and hot air rising upwards in the early stages of a fire, enabling the devices to detect temperature increases or changes in smoke concentration more quickly and accurately, thereby improving the sensitivity and response speed of fire alarm information. Furthermore, the top location offers a wide field of vision and facilitates signal propagation, helping to cover the entire computer room 100 area with early warning signals. It also avoids performance limitations caused by ground obstacles or human interference, further ensuring the safety of the computer room 100 and the reliability of the early warning system.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
