DETAILED DESCRIPTION

[0016] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0017] See also Figure 1-Figure 11 The present invention provides an electrical automation control cabinet, comprising a cabinet body 1, wherein the cabinet body 1 is divided into an upper chamber 11 and a lower chamber 12 by a partition, a partition frame 2 is provided on the back of the upper chamber 11, and a plurality of longitudinally arranged installation areas 21 are formed inside the partition frame 2; like Figure 1 As shown, the partition frame 2 includes a pair of vertically arranged vertical frames 22 and a horizontal frame 23 arranged between the pair of vertical frames 22; strip-shaped threading grooves 24 are evenly arranged on the partition frame 2 around the installation area 21; like Figure 1-Figure 5As shown, a dry powder delivery component 3 is arranged in each partition frame 2, and the dry powder delivery component 3 includes a shell 31 and a storage bin 32 arranged in the shell 31, the bottom of the shell 31 is open, and the bottom of the storage bin 32 is evenly provided with injection ports 33, and one end of the storage bin 32 is connected to an air intake pipe 34; the lower chamber 12 also includes a compression tank 4, which stores compressed carbon dioxide, and the output port of the compression tank 4 is connected to a vertical pipe 5 through a pipeline, and the vertical pipe 5 is arranged on one side of the upper chamber 11, the air intake pipe 34 of the dry powder delivery component 3 is connected to the vertical pipe 5 through a connecting pipeline 6, and each connecting pipeline 6 is evenly provided with a solenoid valve 7, and a main solenoid valve (not shown) is arranged at the output port of the compression tank 4; a camera 8 is also installed on the inner wall of the cabinet 1.

[0018] The partition frame 2 of the present invention divides the cabinet 1 into a plurality of installation areas 21, wherein the electrical components in adjacent installation areas 21 can be connected by means of strip-shaped wire threading grooves 24, which, on the one hand, avoids the exposure of the wires affecting the aesthetics, and on the other hand, avoids the spread of fire after the electrical components catch fire; During the use of the control cabinet, the camera 8 can monitor the installation area 21 in real time. When the camera 8 captures a fire in a certain installation area 21, the main solenoid valve (not shown) is opened first, and then the solenoid valve 7 corresponding to the fire is opened. At this time, the carbon dioxide gas in the compression tank 4 will quickly pass through the vertical pipe 5, the corresponding connecting pipeline 6 and the air inlet pipe 34 and enter the storage bin 32, and the storage bin 32 stores dry powder. After entering the storage bin 32, the carbon dioxide will be discharged from the injection port 33 along with the dry powder, so that the mixed gas formed by the dry powder and carbon dioxide is sprayed above the installation area 21 onto the burning electrical components, thereby extinguishing the fire in the installation area 21, preventing the fire from spreading, and improving the safety performance in the control cabinet.

[0019] In this embodiment, a strip-shaped opening is provided on the front side of the partition frame 2, and the dry powder delivery assembly 3 can be inserted into the partition frame 2 through the strip-shaped opening in a sideways sliding manner.

[0020] like Figure 6-Figure 8As shown, in the present embodiment, the storage bin 32 comprises a first tube body 321 and a second tube body 322 which are sleeved with each other, and the first tube body 321 and the second tube body 322 are sealed at opposite ends thereof, one sealed end of the first tube body 321 is connected to the air intake pipe 34, the first tube body 321 is fixedly assembled in the shell 31, the second tube body 322 is slidably matched with the shell 31 and can only slide at the first position and the second position along the axial direction of the first tube body 321, a preload spring 323 is arranged between the sealed end of the second tube body 322 and the shell 31, the injection port 33 comprises a first arc-shaped groove 331 which is uniformly arranged on the lower half of the first tube body 321 along the length of the first tube body 321, and a second arc-shaped groove 332 which is uniformly arranged on the lower half of the second tube body 322 along the length of the second tube body 322, when the second tube body 322 is in the first position, the first arc-shaped groove 331 is misaligned with the second arc-shaped groove 332 (refer to Fig. 9 As shown in FIG. 1 ), when the second tube body 322 is in the second position, the first arc-shaped groove 331 corresponds to the second arc-shaped groove 332 (refer to FIG. 1 ). Fig.10 as shown).

[0021] Based on the above design, during the use of the control cabinet, under the action of the preload spring 323, the second tube body 322 is in the first position. At this time, the first arc-shaped groove 331 and the second arc-shaped groove 332 are misaligned, and the dry powder is sealed and stored in the space surrounded by the first tube body 321 and the second tube body 322 to prevent the dry powder from being damp and hardened during storage. When carbon dioxide enters the first tube body 321 through the air intake pipe 34, under the gas pressure of carbon dioxide, the second tube body 322 will automatically move from the first position to the second position and further compress the preload spring 323. At this time, the first arc-shaped groove 331 corresponds to the second arc-shaped groove 332, that is, the injection port 33 is opened, and the mixed gas formed by the dry powder and carbon dioxide is sprayed onto the burning electrical components above the fire in the installation area 21, which can extinguish the fire in the installation area 21 and prevent the fire from spreading, thereby improving the safety performance in the control cabinet.

[0022] In this embodiment, the first arc-shaped groove 331 is arranged corresponding to the strip-shaped threading groove 24 on the horizontal frame 23 to prevent the mixed gas formed by the dry powder and carbon dioxide from being blocked by the partition frame 2 after being discharged.

[0023] like Figure 7 As shown, in this embodiment, the air intake pipe 34 is L-shaped, and includes a first air intake section 341 coaxial with the first tube body 321, and a second air intake section 342 perpendicular to the first air intake section 341; A rotating tube 9 is coaxially arranged in the first tube body 321, and one end of the rotating tube 9 extends into the first air inlet section 341 to form a rotating section 91, and the outer wall of the rotating section 91 is tightly fitted with the inner wall of the first air inlet section 341, and a rotating column 92 is fixedly connected in the rotating section 91, and a spiral channel 93 is evenly penetrated through the rotating column 92 along the circumferential direction. A positioning ring 94 is provided at one end of the first tube body 321 close to the air inlet pipe 34, and a bearing 95 is installed between the positioning ring 94 and the rotating tube 9, and a row of jet holes 96 along the length direction of the rotating tube 9 are provided on the outer wall of the rotating tube 9, and the jet holes 96 correspond to the first arc-shaped groove 331.

[0024] Based on the above design, the carbon dioxide is guided through the spiral channel 93 of the rotating column 92, and the rotating tube 9 is rotated by the impact of the carbon dioxide. When the rotating tube 9 rotates, the jet direction of the jet hole 96 on the rotating tube 9 is changed, so that the carbon dioxide entrained dry powder is discharged from the first arc groove 331 and the second arc groove 332, and the gas flow direction is changed, forming a swing wind effect (refer to Fig.11 As shown in the figure, the spray range of the mixed gas can be increased to quickly extinguish the fire, thereby improving the safety performance of the control cabinet.

[0025] like Figure 1 As shown, in this embodiment, the cabinet 1 on both sides of the upper chamber 11 is provided with air outlet grooves 13, and the cabinet 1 on both sides of the lower chamber 12 is provided with air inlet grooves 14. The bottom end of the vertical frame 22 passes through the partition and extends into the lower chamber 12, and an air intake fan (not shown) is installed at the bottom end of the vertical frame 22. When in use, the air intake fan guides air into the partition frame 2, so that the air is discharged from the strip-shaped wire grooves 24 around the installation area 21, dissipating heat for electrical components and circuits, and preventing heat accumulation during the operation of electrical components, which may cause fires in electrical components.

[0026] The present invention also provides a safety monitoring system using the above-mentioned electrical automation control cabinet, including a temperature sensor, a humidity sensor and a smoke sensor arranged in the cabinet body 1, and also including a wireless monitoring automatic fire extinguishing control unit; the wireless monitoring automatic fire extinguishing control unit includes a CPU logic control module, a logic execution control module, a 485 communication interface module, a data storage module, a wireless transmission module, a GPRS communication output module, a power supply management module and a human-machine interface module.

[0027] Among them, the wireless monitoring automatic fire extinguishing control unit collects real-time data of temperature, humidity and smoke through the wireless transmission module, and detects, calculates and judges through the CPU logic control module, and saves it in the storage module.

[0028] After the CPU logic control module performs calculations and judgments, if there is a dangerous situation, it will immediately notify the relevant leaders in the form of text messages through the GPRS communication output module, and quickly transmit the alarm information to the centralized control center through the 485 communication interface module. The logic execution control module drives the external sound and light alarm to promptly and effectively remind the current on-duty personnel to deal with it in time and minimize the loss. When the external power outage occurs, the backup power supply starts immediately to provide power for the wireless monitoring automatic fire extinguishing control unit to ensure the normal output of the alarm information. The human-machine interface uses a touch screen Chinese character display, which is easy to operate.

[0029] Specifically: like Fig.12 As shown, D3 is the CPU logic control module (hereinafter referred to as CPU) of the wireless monitoring automatic fire extinguishing control unit, the power supply is 3.3V, and the 48th pin is the power supply pin; C4, C6 and G1 form an oscillator circuit, which provides the CPU with a reference oscillation frequency of 8MHz, ensuring that the CPU can multiply to an accurate 200MHz operation, ensuring the speed and accuracy of CPU calculations; C7, C8, C9, C10, C11, C12, C13 are power supply filter circuits; D5 is the wireless transmission module of the wireless monitoring automatic fire extinguishing control unit. It is a wireless receiving circuit. After the temperature, humidity and smoke information of the monitoring area is sent by the external monitoring unit, it is transmitted to the CPU through pins 6, 7, 8 and 9. After the CPU receives the information from D5, it makes a judgment through high-speed calculation and now stores the result in D4 (data storage module) for reference. At the same time, it makes corresponding logical control according to the judgment result.

[0030] When the CPU determines that there is a fire alarm, it sends information to the 1 and 3 interfaces of D8 (logic execution module) through the 16 and 17 control interfaces. After receiving the instructions from the CPU, D8 controls the KA1 and KA2 relays to close through the 14 and 16 feet, and controls the external sound and light alarm to sound a fire alarm.

[0031] When the CPU determines that there is a fire alarm, while completing the above alarm, it sends information to the 6th and 7th pins of TX1 (GPRS communication output module) through the 19th and 20th pin control interface. After TX1 receives the instruction from the CPU, it sends the alarm information to the relevant person in charge through the antenna connected to the transmitting pin 19th pin, thus completing the entire monitoring alarm purpose.

[0032] Power supply management module: like Fig.14 As shown, P2 is the external power input interface, and pin 1 of P2 is the ground terminal of the entire system controller. Pin 1 of P2 is connected to the input pin 8 of D15 (PW4203 switching power management chip) through anti-reverse diodes D11 and D12 and filtered by capacitor C17.

[0033] D13 prevents voltage backflow; resistor R37 and light-emitting diode RED form a power display circuit. RED lights up to indicate power is available, and RED off to indicate no external power supply; RONR1 and RONR2 form a reference feedback voltage circuit. D15 monitors the midpoint voltage of the two resistors through pin 4 to control the output voltage; L1 and RPROG1 form an oscillation voltage regulation circuit, which is connected to pins 2 and 7 of D15 to form a circuit for adjusting the output voltage; when the voltage is adjusted to 12V, it is output from pin 3 of D15, and after filtering by C23 and C24 and D16 to prevent reverse power supply, it outputs VOUT, achieving the function of automatic voltage regulation of the power supply.

[0034] P3 is an external power switch, which plays a role in controlling the start and stop. When P3 is closed, the power supply VOUT (+12v) is connected to the input pin 1 of the voltage regulator U1 (78M05) after being filtered by C18 and C20. After being stabilized to +5v by U1, it is output from the 3rd pin of U1, filtered by C21 and C22, and then to the input pin 3 of the voltage regulator N1 (AMS1117-3.3V). After being stabilized to +3.3V by N1, it is filtered by C25 and C26 and used as the power supply for the CPU. In this way, after two-stage voltage stabilization, the 12V has completed the different working voltage levels required by this system controller.

[0035] In this embodiment, the wireless monitoring automatic fire extinguishing control unit quickly transmits the alarm information to the centralized control center through 1RS485 communication (A3, B3), and 2RS485 communication (A4, B4) is reserved. The working principle of RS485 is as follows: Fig.13 As shown (taking A3 and B3 as examples): The power supply system of RS485 is U2. The power supply management module inputs 5V voltage into pins 1 and 2 of U2, and outputs it from pins 3 and 4 after internal conversion to provide power for RS485.

[0036] When the CPU detects an abnormality, the TX and RX interfaces send and receive information, which is connected to the internal power supply 3.3V through the pull-up resistors R40 and R41 to ensure signal stability. The signal is isolated from the external interface through the photoelectric isolation E5 and E6 to ensure that the CPU will not be damaged.

[0037] The CPU's send and receive data is transmitted to pins 1 and 4 of D18 (SP485 chip) via pin 1 of E5 and pin 4 of E6. R44 and R45 are pull-up resistors to stabilize the voltage to 5V. R47 and R49 are bias resistors for the base and collector of the automatic send and receive transistor Q6.

[0038] Pins 5 and 8 of the D18 (SP485) chip are power supply pins; pins 6 and 7 are external communication interfaces, R52 and R53 are pull-up and pull-down resistors of the external interface to ensure the stability of communication; R56 and R57 are connected in series with the external interface circuit to prevent short circuit of the communication line; V4 and V6 are transient diodes, which play the role of voltage clamping of the communication line, that is, to prevent high voltage and lightning strikes.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
