[0022] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Please refer to Figures 1 to 9 An embodiment of the present invention discloses a gas fire extinguishing system monitoring device 00.

[0024] In one embodiment, such as Figures 1-5 As shown, the gas extinguishing system monitoring device 00 includes a housing 1 and a flip cover 2 that is rotatably connected to the housing 1. When the flip cover 2 is closed on the housing 1, the flip cover 2 and the housing 1 together form a box with a hollow cavity. A main board 60 is installed in the hollow cavity of the housing 1. The flip cover 2 is connected to the housing 1 via a hinge 8, and the flip cover 2 can be flipped open and closed relative to the housing 1 via the hinge 8.

[0025] The touchscreen display 3 is mounted on the flip cover 2, and an interface socket 4 is fixed to the back of the touchscreen display 3. Multiple connection interfaces 5 are provided on several sides of the interface socket 4. One of these connection interfaces 5 is a high-definition multimedia interface, which has contact posts 54. The touchscreen display 3 is connected to the contact posts 54 of the high-definition multimedia interface via a ribbon cable 7. The touchscreen display 3 is also electrically connected to the motherboard 60 inside the housing 1 via the ribbon cable 7, the contact posts 54 of the high-definition multimedia interface, and the motherboard 60 inside the housing 1. Simultaneously, the port side of the high-definition multimedia interface extends outward from the side of the interface socket 4 for connecting an external display to achieve video signal output. The remaining connection interfaces 5 on the interface socket 4 are electrically connected to the motherboard 60 inside the housing 1, and also extend outward from the side of the interface socket 4 for connecting external devices, such as USB flash drives, monitors, and host computers.

[0026] In use, external devices exchange data with the motherboard 60 through the corresponding connection interfaces 5 on the side of the interface socket 4. Users input control commands via the touchscreen display 3, which are transmitted to the motherboard 60 via the ribbon cable 7 and the contact pins 54 of the high-definition multimedia interface. The motherboard 60 then executes the corresponding control operations according to preset logic. Simultaneously, external devices (such as USB flash drives, monitors, and host computers) exchange data with the motherboard 60 through the corresponding connection interfaces 5 on the side of the interface socket 4. The touchscreen display 3 receives device status information sent by the motherboard 60 and displays it in real time.

[0027] Since all connection interfaces 5 are centrally located on the interface socket 4 on the back of the touch screen 3 and extend outward from the side of the interface socket 4, the cables of each connection interface 5 are routed in the same direction, avoiding the messy wiring problem caused by the interfaces being scattered in different positions of the housing 1 in the prior art. This facilitates centralized cable management and subsequent maintenance. At the same time, maintenance personnel only need to open the flip cover 2 to check and plug and unplug all connection interfaces 5 from the side of the interface socket 4, without having to operate them separately in different positions of the housing 1, which significantly improves maintenance convenience. The flip cover 2 is connected to the housing 1 by a hinge 8, which is simple and reliable in structure and suitable for scenarios such as the gas extinguishing system monitoring device 00, which is opened and closed occasionally and does not require frequent operation.

[0028] In one embodiment, such as Figure 5 and Figure 6 As shown, multiple connection interfaces 5 are distributed on at least three sides of the interface socket 4. By distributing multiple connection interfaces 5 on at least three sides of the interface socket 4, the side space of the interface socket 4 is fully utilized. Compared with concentrating all interfaces on the same side, this avoids the difficulty of plugging and unplugging cables due to overcrowding of interfaces. At the same time, each side of the interface socket 4 can be independently routed, which helps to organize the internal cable layout.

[0029] Specifically, the multiple connection interfaces 5 are divided into a first group of connection interfaces 515, a second group of connection interfaces 525, and a third group of connection interfaces 535. The first group of connection interfaces 515 is located on the first side of the interface socket 4. The first group of connection interfaces 515 includes at least one of the following: a power interface 62, a high-definition multimedia interface (HDMI), a universal serial bus interface (USB), a serial communication interface (RS232), an Ethernet interface, and a bus interface (RS485 / CAN). All of the first group of connection interfaces 515 extend outward from the first side of the interface socket 4. The second group of connection interfaces 525 is located on the second side of the interface socket 4. The second group of connection interfaces 525 includes at least one of the following: a cellular communication interface (4G), a satellite positioning interface (BDGPS), a near-field wireless communication interface (WIFI BT), a speaker interface (SPK), a microphone interface (MIC), a general purpose input / output interface (GPIO), and a physical button interface (KEY). All of the second group of connection interfaces 525 extend outward from the second side of the interface socket 4. The third set of connection interfaces 535 is located on the third side of the interface socket 4. This third set of connection interfaces 535 includes at least one of a debug interface (DEBUG), a universal asynchronous receiver / transmitter (UART), and a universal serial bus interface (USB 2.0), and all of these interfaces extend outward from the third side of the interface socket 4. By grouping multiple sets of connection interfaces 5 onto different sides of the interface socket 4, different types of connection interfaces 5 are distributed on different sides according to their function or usage frequency. This allows maintenance personnel to quickly locate the required connection interface 5 based on the side where the interface is located after the flip cover 2 is opened, further improving the convenience of maintenance and repair.

[0030] In one embodiment, the gas extinguishing system monitoring device 00 further includes a power supply module 62, a backup power supply 62, and at least one circuit board 61. The power supply module 62 is housed within the housing 1. Its input terminal is connected to an external main power supply 62 (such as AC power), and its output terminal is electrically connected to the main board 60 and the touch screen 3, respectively. It converts the external main power supply 62 into the operating voltage required by the main board 60 and the touch screen 3, and provides operating power to them. The backup power supply 62 is also housed within the housing 1 and is electrically connected to the power supply module 62. When the external main power supply 62 is supplying power normally, the power supply module 62 charges the backup power supply 62, keeping the backup power supply 62 fully charged. When the external main power supply 62 fails, the power supply module 62 automatically switches to the backup power supply mode, and the backup power supply 62 provides working power to the motherboard 60 and the touch screen 3, so as to ensure that the gas extinguishing system monitoring device 00 can still maintain normal operation after the main power supply 62 fails. This ensures that in emergency situations such as fires, even if the main power supply 62 fails, the gas extinguishing system monitoring device 00 can still continuously monitor the fire situation in the protected area and promptly initiate the fire extinguishing procedure.

[0031] The circuit board 61 is housed within the casing 1 and electrically connected to the main board 60. It connects to external field devices such as smoke detectors, heat detectors, emergency start / stop buttons, manual / automatic switch boxes, gas release alarms, audible and visual alarms, input / output modules, and solenoid valves. The circuit board 61 provides power 62 and communication signals to the external field devices, ensuring their normal inspection, alarm, startup, and feedback. By installing the circuit board 61, the gas extinguishing system monitoring device 00 can monitor the operating status of external field devices within the protected area in real time. In the event of a fire, it sends start commands to actuators such as solenoid valves via the circuit board 61, achieving automatic fire extinguishing control.

[0032] The electrical connections of the gas extinguishing system monitoring device 00 are as follows: the touch screen 3 is electrically connected to the main board 60 via the ribbon cable 7 and the contact post 54 of the high-definition multimedia interface; each connection interface 5 on the side of the interface socket 4 is electrically connected to the main board 60; the circuit board 61 is electrically connected to the main board 60 and the external field equipment; the power supply module 62 is electrically connected to the main board 60 and the touch screen 3; and the backup power supply 62 is electrically connected to the power supply module 62.

[0033] The signal flow of the gas extinguishing system monitoring device 00 is as follows: User-input touch commands are collected by the touchscreen display 3 and transmitted to the mainboard 60 via the ribbon cable 7 and the contact post 54 of the high-definition multimedia interface. The mainboard 60 processes the commands according to preset logic and then sends the control commands to external field devices via the loopback board 61. Simultaneously, the status information collected by the external field devices is reported to the mainboard 60 via the loopback board 61. The mainboard 60 then transmits the processed device status information to the touchscreen display 3 for real-time display via the ribbon cable 7 and the contact post 54 of the high-definition multimedia interface. External devices exchange data with the mainboard 60 through the connection interface 5 on the side of the interface socket 4.

[0034] The power supply direction is as follows: the external main power supply 62 is converted by the power supply module 62 and then supplied to the motherboard 60 and the touch screen 3 respectively; when the main power supply 62 is de-energized, the backup power supply 62 is automatically activated and continues to supply power to the motherboard 60 and the touch screen 3 through the power supply module 62.

[0035] In one embodiment, there are two motherboards 60, namely a first motherboard 60 and a second motherboard 60, which are redundant to each other. During normal operation, the first motherboard 60 serves as the primary motherboard 60, undertaking all computational and control tasks, while the second motherboard 60 serves as the backup motherboard 60, synchronizing the data and status of the first motherboard 60 in real time. When the first motherboard 60 fails, the second motherboard 60 automatically takes over the control functions, ensuring the continuous operation of the gas extinguishing system monitoring device 00 without interruption, thereby avoiding the safety hazard of the entire system being paralyzed due to the failure of a single motherboard 60.

[0036] In one embodiment, the bottom and / or top of the housing 1 are provided with inlet holes, and removable plugs are provided at the inlet holes. The inlet holes are used for external cables to pass through the housing 1 to connect to the mainboard 60 or other electrical components inside the housing 1. The plugs are placed over the inlet holes at the factory to keep the housing 1 closed and prevent dust and foreign objects from entering the housing 1. When it is necessary to insert external cables, the plugs are removed from the inlet holes, exposing the inlet holes for the cables to pass through. The gas extinguishing system monitoring device 00 keeps the housing 1 closed during factory transportation and before installation to prevent dust and foreign objects from entering the housing 1 and contaminating or damaging electrical components. During on-site installation, the plugs at the corresponding inlet holes can be selectively removed according to actual wiring requirements, while the plugs are retained at unused inlet holes, thus meeting both factory protection and flexible on-site wiring needs.

[0037] In one embodiment, the top area of ​​the touch display screen 3 is provided with touch buttons, including at least one of a reset button, a self-test button, a mute button, and a home button. The reset button sends a reset command to the motherboard 60 to restore the controller to its initial state; the self-test button triggers a system self-test program to check whether each functional module of the controller is working properly; the mute button silences the alarm sound; and the home button returns the touch display screen 3 to the main monitoring interface. Each touch button is electrically connected to the motherboard 60, and the user can send corresponding control commands to the motherboard 60 by touching the corresponding button area. By placing the touch buttons in the top area of ​​the touch display screen 3, the buttons and the display screen are integrated into one unit, allowing the user to perform button operations while viewing information on the display screen, eliminating the need to switch between the display screen and separately configured physical buttons.

[0038] In one embodiment, the flip cover 2 is provided with a speaker hole 21, and a speaker is provided inside the housing 1, with the speaker's sound-emitting end positioned corresponding to the speaker hole 21. The speaker is electrically connected to the main board 60. When the main board 60 detects an alarm signal, the speaker emits an alarm sound. The alarm sound is transmitted through the speaker's sound-emitting end to the speaker hole 21 and then emitted outward through the speaker hole 21 to alert on-site personnel. The speaker being positioned inside the housing 1 and the speaker hole 21 being positioned on the flip cover 2 reduces the risk of dust intrusion and mechanical damage; the speaker's sound-emitting end being positioned corresponding to the speaker hole 21 ensures that the alarm sound can be effectively emitted through the speaker hole 21 on the flip cover 2.

[0039] In one embodiment, such as Figure 7As shown, the gas extinguishing system monitoring device 00 also includes a locking assembly 9, which is used to lock the flip cover 2 onto the housing 1 to prevent the flip cover 2 from being opened without authorization. The locking assembly 9 is disposed between the flip cover 2 and the housing 1. Specifically, one part of the locking assembly 9 is located on the flip cover 2, and the other part is located on the housing 1. The two parts cooperate with each other to achieve locking when the flip cover 2 is closed. The locking assembly 9 includes a fastening member 91, a rotating locking member 92, and a locking hole 93. The fastening member 91 is fixedly disposed on the inner edge of the flip cover 2 and moves with the flip cover 2 as it flips. The rotating locking member 92 is rotatably disposed on the housing 1, located at the front edge of the housing 1 corresponding to the fastening member 91. The locking hole 93 is disposed on the rotating locking member 92, and the opening of the locking hole 93 faces the outside of the housing 1 to facilitate the insertion of a key. When the flip cover 2 is flipped to the closed position relative to the housing 1, the fastening member 91 moves with the flip cover 2 to a position corresponding to the rotating locking member 92. The rotating locking member 92 engages with the fastening member 91, locking the flip cover 2 onto the housing 1 and preventing it from opening. When the key is inserted into the locking hole 93 and turned, the key drives the rotating locking member 92 to rotate, disengaging the rotating locking member 92 from the fastening member 91, allowing the flip cover 2 to be flipped open. By controlling the opening of the flip cover 2 with a key, only personnel with the key can open the flip cover 2, preventing unauthorized personnel from accidentally operating or touching internal electrical components, thus improving equipment safety.

[0040] In one embodiment, such as Figure 8 As shown, the fastening component 91 is a sheet-like bent piece, roughly "L"-shaped, including a fixing part 911 and a hook part 912. The fixing part 911 is flat, and its surface is attached to the inner surface of the flip cover 2. The fixing part 911 is fixedly connected to the flip cover 2, for example, by welding or bolting, to ensure that the fastening component 91 does not loosen or shift during long-term opening and closing of the flip cover 2. The hook part 912 is formed by bending one end of the fixing part 911. The end of the hook part 912 is slightly raised, forming a hook-shaped structure for engaging with the rotating locking component 92. By providing the hook part 912, the fastening component 91 can form a stable engagement with the rotating locking component 92, ensuring the reliability of the locking when the flip cover 2 is closed. The fastening component 91 adopts a sheet-like bent piece structure, which is simple to manufacture and has a low cost.

[0041] In one embodiment, such as Figure 9As shown, the rotating locking member 92 includes a rotating body 921 and a toggle part 922. The rotating body 921 is generally cylindrical or disc-shaped and is rotatably mounted on the housing 1 via a pivot. The rotating body 921 can rotate freely within the housing 1 about its axis. A locking hole 93 is provided on the rotating body 921. The locking hole 93 is an irregularly shaped hole that matches the key. After the key is inserted, it can form a circumferential limiting fit with the rotating body 921. When the key is turned, the rotating body 921 rotates accordingly. The toggle part 922 is provided on the rotating body 921 and extends outward from the outer circumference of the rotating body 921. It swings as the rotating body 921 rotates. When the flip cover 2 is closed, the toggle part 922 engages with the hook part 912 of the fastening member 91, locking the flip cover 2 onto the housing 1. When the key is inserted into the locking hole 93 and turned, the key drives the rotating body 921 and the actuating part 922 to rotate together. After the actuating part 922 rotates with the rotating body 921, it disengages from the hook part 912 of the fastening member 91, and the flip cover 2 can be flipped open. The locking and unlocking of the flip cover 2 is achieved by the engagement and disengagement of the actuating part 922 and the hook part 912, which is simple and reliable. The actuating part 922 and the hook part 912 are engaged by an engagement method, which eliminates the need for an additional spring or locking tongue structure, simplifying the number of parts in the locking assembly 9.
