[0029] Embodiment 1
[0030] As Figure 1 and Figure 2 shown, this embodiment provides a fire prevention system for an elevated warehouse, including an elevated warehouse 7 and a stacker crane 1. A fire hydrant 2 is provided on the stacker crane 1. The fire prevention system for the elevated warehouse further includes a detection module 3, a data acquisition module 4, a data processing module 5, and a control module 6. The detection module 3 is used to detect the temperature value and smoke concentration value in each area of the elevated warehouse 7 and use them as detection data. The data acquisition module 4 is used to receive the detection data. The data processing module 5 is used to analyze and process the detection data. The control module 6 can control the movement of the stacker crane 1 and the opening and closing of the fire hydrant 2 according to the feedback of the data processing module 5.
[0031] Specifically, after obtaining the detection data, the detection module 3 sends it to the data acquisition module 4 in the form of an analog signal. The data acquisition module 4 converts the analog signal into a digital signal and then sends it to the data processing module 5. The data processing module 5 is internally provided with a discrimination module. Temperature standard values and smoke concentration standard values are preset in the discrimination module. When the temperature value and smoke concentration value received by the data processing module 5 are higher than the temperature standard value and smoke concentration standard value, the data is sent to the control module 6. The control module 6 then sends an instruction to the stacker crane 1 to control its movement to the target position. After the stacker crane 1 is in place, the control module 6 sends an instruction to the fire hydrant 2 to control it to extinguish the fire source.
[0032] The fire protection system of this high-bay warehouse uses the detection module 3 to be able to monitor the temperature values and smoke concentration values of each area in the high-bay warehouse 7 in real time. Then, with the help of the data acquisition module 4 and the data processing module 5, the measured detection data is received, analyzed, and processed, enabling the control module 6 to, according to the feedback of the detection data, timely control the stacker 1 to move to the fire point, open the fire hydrant 2, and extinguish the fire source. Thus, it replaces the scheme of manually opening the fire hydrant 2, avoids the risk of being unable to extinguish the fire in time, thereby accelerating the fire extinguishing speed, ensuring the fire control ability, and enhancing the automation degree of the fire extinguishing operation.
[0033] Exemplarily, the stacker 1 is used to pick up and place goods from the high-bay warehouse 7. Specifically, the goods are tobacco bale boxes.
[0034] In this embodiment, the data processing module 5 is a computer. Specifically, the model of the computer is PC SIMATIC IPC 677E.
[0035] In this embodiment, a solenoid valve is provided at the output end of the fire hydrant 2, and the control module 6 is electrically connected to the solenoid valve to open and close the fire hydrant 2; the control module 6 is electrically connected to the stacker 1 to drive the stacker 1. Specifically, the input end of the solenoid valve is electrically connected to the output end of the control module 6, and the input end of the stacker 1 is electrically connected to the output end of the control module 6.
[0036] In this embodiment, the solenoid valve is connected to the control module 6 through a serial port or USB. The control module 6 sends instructions to the solenoid valve through the serial port or USB to control its opening and closing; the control module 6 and the stacker 1 communicate through a USB485 (USBCAN) gateway converter. One end of the USB485 (USBCAN) gateway converter is connected to the output port of the control module 6, and the other end is connected to the input terminal of the drive motor of the stacker 1. The control module 6 sends instructions to the drive motor through the USB485 (USBCAN) gateway converter to control the operation of the stacker 1.
[0037] In this embodiment, the detection module 3, the data acquisition module 4, the data processing module 5, and the control module 6 are electrically connected in sequence. Specifically, the output end of the data acquisition module 4 is electrically connected to the input end of the data processing module 5, and the output end of the data processing module 5 is electrically connected to the input end of the control module 6. The above connection method is simple and reliable, with the advantages of long service life, high connection stability, and good working effect.
[0038] Embodiment Two
[0039] Such as Figure 3 And Figure 4As shown in the figure, the elevated warehouse fire prevention system of the second embodiment is basically the same as that of the first embodiment above. The difference between the two is that the detection module 3 includes a number of temperature sensors 31 distributed in various areas of the elevated warehouse 7, and each temperature sensor 31 is used to detect the temperature value of an area in the elevated warehouse 7; the detection module 3 includes a number of smoke sensors 32 distributed in various areas of the elevated warehouse 7, and each smoke sensor 32 is used to detect the smoke concentration value of an area in the elevated warehouse 7. In other embodiments of the present embodiment, there are cases where only a number of temperature sensors 31 or a number of smoke sensors 32 are provided.
[0040] By setting the temperature sensors 31 and the smoke sensors 32, the temperature and smoke concentration in each area of the elevated warehouse 7 can be monitored, thus ensuring the coverage rate and accuracy of the monitoring.
[0041] In this embodiment, the temperature sensors 31 are electrically connected to the data acquisition module 4 through shielded cables 8; the smoke sensors 32 are electrically connected to the data acquisition module 4 through shielded cables 8. In other embodiments of the present embodiment, there are cases where only the temperature sensors 31 or the smoke sensors 32 are electrically connected to the data acquisition module 4 through shielded cables 8.
[0042] Specifically, the temperature sensors 31 and the smoke sensors 32 are electrically connected to the input end of the data acquisition module 4 through shielded cables 8.
[0043] In this application, by using shielded cables 8 to transmit signals, external electromagnetic interference is prevented from entering the cables, and the electrical signals transmitted internally are blocked from radiating out to interfere with the operation of other devices. By setting signal isolators 10 to isolate the noise sources and the signals of the devices, the input end and the output end, the transmission of the electrical signals is made more stable.
[0044] The shielded cable 8 is used to transmit the signals collected by the temperature sensors 31 and the smoke sensors 32, and isolate the electromagnetic field noise source from the sensitive devices, cutting off the propagation path of the noise source. It is a transmission line that uses a metal mesh braid to wrap the signal wire. The braid is generally red copper or tinned copper. The shielding layer of the shielded cable 8 is mainly made of non-magnetic materials such as copper and aluminum, and the thickness is very thin; the shielding is divided into active shielding and passive shielding. The purpose of active shielding is to prevent the noise source from radiating outwards, which is the shielding of the noise source; the purpose of passive shielding is to prevent the sensitive devices from being interfered by the noise source, which is the shielding of the sensitive devices; the shielded cable 8 uses the principles of reflection, absorption and skin effect of metals on electromagnetic waves to effectively prevent external electromagnetic interference from entering the cable, and at the same time prevent the internal signals from radiating out and interfering with the operation of other devices.
[0045] The so-called skin effect refers to the distribution of current in the cross-section of a conductor tending to the surface distribution as the frequency increases. The higher the frequency, the smaller the skin depth, that is, the weaker the penetration ability of electromagnetic waves at higher frequencies.
[0046] In this embodiment, the control module 6 is electrically connected to the stacker 1 through the signal isolator 10; the control module 6 is electrically connected to the fire hydrant 2 through the signal isolator 10. In other implementation manners of this embodiment, there is a situation where the control module 6 is only electrically connected to the stacker 1 or the fire hydrant 2 through the signal isolator 10.
[0047] Specifically, the signal isolator 10 can effectively isolate the electrical relationship between the power supply and the signal between the signal source and the receiving end. The signal isolator 10 uses a converter to convert the analog signal into a digital signal, transmit it to the receiving end, and then convert the digital signal back into an analog signal by the converter, thereby realizing electrical isolation of the signal. The signal isolator 10 is a one-in-multiple-out isolator, which can convert the digital command of the control module 6 into an analog command and send it to the drive motor of the stacker 1 and the solenoid valve of the automatic fire hydrant 2. At the same time, the signal isolator 10 can also amplify and filter the analog signal.
[0048] Exemplarily, the high-rise warehouse fire protection system further includes an alarm device 9, and the alarm device 9 is electrically connected to the control module 6. Specifically, the input end of the alarm device 9 is electrically connected to the output end of the control module 6.
[0049] While sending commands to the stacker 1 and the automatic fire hydrant 2, the control module 6 also sends an alarm command to the alarm device 9, causing the speaker and the audible and visual alarm to emit audible and visual alarm signals, so as to give an immediate reminder in case of an abnormal situation, thereby enabling the staff to be informed of the danger as early as possible and realizing timely control of the fire situation.
[0050] In this embodiment, the alarm device 9 includes a speaker and an audible and visual alarm. In other implementation manners of this embodiment, the alarm device 9 only includes a speaker or an audible and visual alarm.
[0051] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
