Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Fig. 1 and 2 are schematic structural diagrams of a fire detection system of a communication base station according to the present invention. The communication base station fire detection system is applied to fire prevention of the communication base station. As is known, a communication base station has a machine room in which various devices and energy storage batteries are installed. To save space and keep clean, these devices are placed in cabinets. And the energy storage battery is accommodated in a sealed case. Meanwhile, the sealing boxes are also arranged in the cabinet, so that the cabinet is tidy, and can be stacked together to increase the space utilization of a machine room. The communication base station fire detection system comprises a power system fire detection group 10 arranged on the cabinet, a seal box fire detection group 20 arranged on the seal cabinet, an initialization setting module 30, a data acquisition module 40, a judgment module 50, a control module 60 and a data management platform 70. It is understood that the fire detection system of the communication base station further includes other functional modules, such as an electrical connection component, a central processing unit, various switches, etc., which are well known to those skilled in the art and will not be described herein.
Each detection sensor of the power system fire detection group 10 is disposed on the cabinet to detect a working environment in the cabinet and a working state of each working module in the cabinet. The power system fire detection group includes a current detection unit 11, a remaining power detection unit 12, and a fault arc monitoring unit 13. The current detection unit 11 may include a current transformer, which may be installed on line bodies of each main loop of the input and the dc output of the utility power, and is configured to detect whether the current input and output are normal. The current transformer is a prior art, is used for detecting the current magnitude, and is not described in detail here. The current detection unit 11 can obtain the current value of the mains supply input or the direct current output, and when a fault such as a short circuit or a broken circuit occurs, each main loop of the mains supply input or the direct current output changes, so that the change can be detected to perform fault diagnosis. The residual electric quantity detection unit 12 may be a residual current transformer, and is installed on a main loop of the commercial power input and output, and detects the residual current in the system, and determines whether the system has an electric leakage or short circuit condition. Leakage is a very common and serious consequence fault that can cause a fire accident and is not predictive. By detecting the remaining power detecting unit 12, the leakage and short circuit conditions can be known in real time. The fault arc monitoring unit 13 may be a fault arc detector, and is installed on a main circuit of a commercial power to detect whether the quality of an arc generated by the commercial power meets requirements. The power system fire detection group further includes a line or surface temperature detection unit 14, a DO unit 15, and a DI unit 16. The wire body or surface temperature detection unit 14 is disposed on an important input/output wire body, or on the surface of some important equipment, to detect the input/output temperature of the wire body and the surface temperature of the important equipment. When the temperature is monitored to be abnormal, abnormal data can be provided for processing. The DO unit 15 is used for controlling external components, such as a circuit breaker, or for cutting off input and output of equipment, such as on/off of a fire fighting solenoid valve. The DO unit 15 refers to a programmable controller, i.e. an input/output interface of the PLC, which is a Digital output module (Digital Out), and is an existing interface unit of the PLC, and is not described herein again. The DI unit 16 is also an existing interface unit of the PLC for monitoring the switching amount of external devices such as circuit breakers, contactors, etc. The command execution of the control module 60 can be completed by the DO unit 15 and the DI unit 16. The power system fire detection group 10 may further include a voltage detection unit 17, and the voltage detection unit 17 includes at least one voltage detection sensor, and the voltage detection unit is disposed on a loop of the commercial power to detect an input or output voltage value. Whether the input and the output of the commercial power are normal can be judged by collecting the voltage value.
Each of the detection sensors of the sealed-box fire detection group 20 is provided on the sealed box. Since a large number of battery packs are accommodated in the sealed case, the characteristics of the battery packs are different from those of various electric devices in the cabinet. The arrangement of the detection sensors on the seal box fire detection group 20 should also be different. The seal box fire detection group 20 includes a temperature sensor 21, a humidity sensor 22, a gas detection sensor 23, a smoke detection sensor 24, a pressure sensor 25, and an illuminance detection sensor 26. The temperature sensor 21 may include a plurality of temperature probes installed at different regions of the surface of the battery case, particularly, at locations where high temperatures are likely to be generated, to detect abnormal information of the battery temperature. It is conceivable that a corresponding position of each battery box should be provided with such a temperature sensor 21. The temperature sensor 22 is mounted inside the sealed box, in particular at the bottom thereof, for detecting air humidity conditions inside the sealed box and battery leakage conditions. The gas detection sensor 23 is installed at the top of the hermetic container to monitor an important gas component inside the hermetic container, particularly, to detect gas generated when a fire occurs. Because in the sealed case, when the battery is out of order such as leakage or short circuit, it first emits gas such as HF gas. Abnormality of the battery can be detected by the gas detection sensor 23. The smoke detection sensor 24 is disposed at the top of the interior of the enclosure and is used for the composition of smoke within the enclosure. When the battery produces smoke, indicating that it is burning soon, the hazardous program is high and needs to be disposed of immediately. The pressure sensor 25 is also installed at the top of the inside of the hermetic container for detecting the air pressure inside the hermetic container. When gas or smoke is generated, the pressure inside the airtight box increases, and if it continues to increase, explosion occurs. The illuminance detection sensor 26 is disposed at the top of the inside of the sealed case and serves to detect the illuminance value inside the sealed case 26. The inside of the sealed box can be known at any time through the sealed box fire detection group 20, so that different fire extinguishing modes can be selected to deal with the situation.
The initialization setting module 30 is configured to initialize the current detection unit 11, the remaining power detection unit 12, the fault arc monitoring unit 13, the line or surface temperature detection unit 14, the temperature sensor 21, the humidity sensor 22, the gas detection sensor 23, the smoke detection sensor 24, the pressure sensor 25, and the alarm threshold corresponding to the illuminance detection sensor 26. When the data detected by each detection sensor is larger than the corresponding warning threshold, the cabinet or the sealed box is considered to have risk and should be processed according to actual conditions. It is understood that the alarm threshold corresponding to each detection sensor should be set according to actual conditions, and is not described one by one here.
The data acquisition module 40 is used for acquiring data detected by the power system fire detection group 10 and the seal box fire detection group 20. The data collection module 40 may be a central processor that collects data from the source system fire detection groups 10 and the seal box fire detection groups 20 and classifies them for later use.
The comparison module 50 is configured to compare the data warning thresholds acquired by the data acquisition module 40, so as to obtain which data or data is/are abnormal. When one or more data is abnormal, a control signal is output and processed by the control module 60. The comparison module 50 may also be a function of the central processing unit and will not be described in detail herein.
The control module 60 may be a processor, a microprocessor, or a PLC, which controls the working state or working environment of the equipment inside the cabinet and the sealing box according to the output command of the comparison module 50. The control module 60 is mainly used for controlling the working states of the switch and the fire extinguishing device. The switch may be a circuit breaker or contactor for breaking various circuit connections for the purpose of quickly cutting off the power supply to prevent further deterioration of the accident. The fire extinguishing device may be a sprinkler system or an electrically controlled fire extinguisher. The control module 60 can control the on-off of the switch and the on-off of the fire extinguishing device according to the data detected by each detection sensor, thereby achieving the purpose of preventing in advance.
The data management platform 70 is configured to upload the data collected by the data collection module 40, so as to facilitate later fault analysis and later system learning. The data management platform 70 may include further functional modules such as a visualization data platform for visualizing the data and organizing operations and maintenance according to alarm categories, so that the data is saved, re-analyzed, and reused. The visual data platform is used for displaying the data collected by the data collection module and warning data.
The communication base station fire detection system also includes a single data anomaly determination module 80. The single data abnormality determining module 80 is configured to determine the abnormal data and other normal data to determine whether the abnormal data is a true abnormality. For example, if the enclosure catches fire and smokes, the temperature and the data returned by the smoke sensor must exceed the alarm threshold. However, if only the temperature exceeds the alarm threshold, and the data returned by the gas sensor and the smoke sensor do not exceed the alarm threshold, the sealed cabinet is considered to be safe and may only be operated in overload, and at the moment, only ventilation and heat dissipation need to be started. If the temperature is detected and the smoke data exceeds the alarm threshold, then it is assumed that a battery failure is likely and subsequent smoking, short circuiting, or even fire will occur, and then the action taken is to close the air inlet and then open the smoke vent. However, if only one smoke data exceeds the alarm threshold and the other data is normal, it is possible that smoke is flowing in from the outside, and the smoke sensation is considered false. Also, if only the gas data exceeds the alarm threshold, but the others are normal, then it can be considered a false positive. Therefore, only if the gas detection exceeds the alarm threshold value, and the temperature and the smoke do not exceed the threshold value, the fire, the short circuit and the smoke are not certainly caused, and at the moment, the nearby residents may burn garbage and the like.
The communication base station fire detection system may further include a single warning data acquisition module 90 and a severity determination module 91. In order to realize the smooth execution of the severity determination module 91, the initialization setting module 30 is further configured to set severity warning thresholds corresponding to the respective detection sensors. The single warning data acquisition module 90 can set data requiring a single warning, such as temperature, gas, pressure, fault arc, etc., according to the user's requirements. However, the single warning data acquisition module 90 is only used for acquiring the detection value of one sensor when the data acquired by the data acquisition module 40 is greater than the warning threshold value. The severity program determination module 90 is then used to compare the comparison made by the determination module 40 with the severity alert threshold and determine the severity based on the comparison. When the comparison is greater than the critical warning threshold, the control module 60 outputs to turn off the switch and turn on the fire suppression device. Of course, the switch may be a circuit breaker or a contactor for turning off or on the electric connection between the utility power and the cabinet.
Compared with the prior art, the communication base station fire detection system provided by the invention firstly divides equipment in a base station into different fire-fighting targets, namely, a cabinet and a seal box for accommodating batteries are separated, and various sensors are respectively arranged, namely, a power system fire detection group 10 is arranged in the cabinet, wherein the power system fire detection group 10 comprises a current detection unit 11, a residual electric quantity detection unit 12 and a fault electric arc monitoring unit 13 for detecting the working condition and the working environment of the cabinet.
