It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0041] Figure 1 It is a schematic structural diagram of a multi-source heterogeneous data transmission device provided by an embodiment of the present utility model. As Figure 1 shown, the multi-source heterogeneous data transmission device includes: an accommodating box 10, a transmission component disposed inside the accommodating box 10, and a protection component disposed outside the accommodating box 10.

[0042] The accommodating box 10 includes a box body and a box door that are opposed to each other ( Figure 1 not shown in the figure), and the box body and the box door are rotatably connected by a hinge (such as a hinge) so that the operation and maintenance personnel can open / close the accommodating box 10 through the box door.

[0043] A sealing gasket 12 is provided between the box body and the box door, and the sealing gasket 12 is used to improve the airtightness of the accommodating box 10 and ensure that the inside of the accommodating box 10 is in a sealed state after the box door is closed.

[0044] Optionally, a handle can be provided on the cabinet door to facilitate the opening / closing of the cabinet door.

[0045] Optionally, there are several pairs of threaded holes 11 on the side of the cabinet door and the cabinet body away from the hinge (if there is a handle on the cabinet door, it is the side close to the handle), so that the maintenance personnel can tighten the cabinet body and the cabinet door with bolts after the cabinet door is closed, thereby further improving the tightness of the accommodation box 10.

[0046] The protection component includes a display circuit 21, a pressure sensor 22 and a valve 23.

[0047] The interior of the accommodation box 10 is in a sealed state. The valve 23 is communicated with the interior of the accommodation box 10. For example, a hole is opened on the accommodation box 10, and a connecting pipe is welded in the hole. The valve 23 is communicated with the connecting pipe. The valve 23 is used to add inert gas to the interior of the accommodation box 10.

[0048] The pressure sensor 22 is electrically connected to the display circuit 21; the pressure sensor 22 is communicated with the interior of the accommodation box 10. For example, a hole is opened on the accommodation box 10, and a connecting pipe 24 is welded in the hole. One end of the pressure sensor 22 is communicated with the connecting pipe 24. The pressure sensor 22 is used to detect the gas pressure inside the accommodation box 10; the display circuit 21 is used to display according to the gas pressure.

[0049] Since the interior of the accommodation box 10 is in a sealed state and the valve 23 can add inert gas to the interior of the accommodation box 10, the influence of external air, water vapor and dust on the internal electronic components can be avoided, and the electrical performance, service life and safety of the internal electronic components in the accommodation box 10 can be improved. At the same time, the pressure sensor 22 can detect the gas pressure inside the accommodation box 10, and the display circuit 21 can display according to the gas pressure, thereby realizing the monitoring of the gas pressure of the inert gas, enabling the maintenance personnel to replenish the gas in time when the gas pressure of the inert gas is too low.

[0050] Optionally, the display circuit 21 can be arranged in the protection box 25 of the accommodation box 10, so that the protection box 25 can protect the display circuit 21 and prevent the display circuit 21 from being exposed to the external environment.

[0051] Inert gas is also called noble gas and has very stable chemical properties, so it is very difficult to react with other elements. Optionally, the inert gas includes the following six elements: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn).

[0052] Preferably, the inert gas includes sulfur hexafluoride and / or nitrogen. Both sulfur hexafluoride and nitrogen have high electrical insulation properties, which can effectively prevent the flow of current. At the same time, when the current is interrupted, they have good arc extinguishing ability and can quickly extinguish the arc, thus achieving the safe disconnection of the current. In addition, the heat conduction ability of sulfur hexafluoride is better than that of air, close to that of helium and hydrogen with better heat conduction ability. Its insulation strength in a uniform electric field is 2.5 times that of air. When the gas pressure is 0.2 MPa, the insulation strength of sulfur hexafluoride is equivalent to that of insulating oil.

[0053] The transmission component includes a power supply unit 31 and at least two circuit boards 32 ( Figure 1 as shown in one circuit board 32). The power supply unit 31 supplies power to each circuit board 32, the pressure sensor 22, and the display circuit 21 respectively, so as to ensure the normal operation of the multi-source heterogeneous data transmission device.

[0054] The inner wall of the accommodation box 10 is provided with at least two pairs of fixing structures 13. One pair of fixing structures 13 is used to fix one circuit board 32; at least two circuit boards 32 are used to transmit multi-source heterogeneous data. Refer to Figure 1 It can be seen that usually one pair of fixing structures 13 is respectively arranged on the left and right sides of the side wall of the accommodation box 10. The fixing structure 13 and the side wall of the accommodation box 10 are fixed by adhesive / fasteners, so as to ensure that the circuit board 32 is parallel to the horizontal plane.

[0055] Since this solution uses at least two circuit boards 32 to transmit multi-source heterogeneous data, that is, uses a split design to transmit data. When a failure occurs, the corresponding circuit board 32 can be replaced, avoiding the problem of replacing the entire circuit board when an integrated circuit board fails, and reducing the maintenance cost. At the same time, there is no need for bolt fixation between the circuit board 32 and the fixing structure 13, which is convenient for maintenance personnel to disassemble and improves the maintenance efficiency.

[0056] In one embodiment, the number of circuit boards 32 is 5;

[0057] The 5 circuit boards are respectively: a data receiving circuit board, a data processing circuit board, a data storage circuit board, a data sending circuit board, and a control circuit board.

[0058] Specifically, the data receiving circuit board can receive multi-source heterogeneous data by wireless or wired means and send the multi-source heterogeneous data to the data processing circuit board. Optionally, the data receiving circuit board can support the priority marking function of data.

[0059] The data processing circuit board can process multi-source heterogeneous data (for example, if the data receiving circuit board marks the priority of the data, the data processing circuit board can also sort the multi-source heterogeneous data according to the priority to ensure that key data can be processed first), such as format conversion, encryption, etc.

[0060] The data storage circuit board can store multi-source heterogeneous data, that is, it provides a buffering function for multi-source heterogeneous data, ensuring the continuity and stability of data transmission. Optionally, the data storage circuit board can support the functions of fast retrieval and access of data.

[0061] The data sending circuit board can send the processed multi-source heterogeneous data to the target device.

[0062] The control circuit board is used to manage and coordinate the work of the data receiving circuit board, the data processing circuit board, the data storage circuit board, and the data sending circuit board, monitor the working states of each circuit board, and ensure the stability and security of the operation of the multi-source heterogeneous data transmission device.

[0063] Furthermore, the data receiving circuit board and the data sending circuit board may or may not have antennas. When the data receiving circuit board and the data sending circuit board do not have antennas, the transmission component may further include an antenna 33. The antenna 33 is disposed outside the accommodation box 10 and is electrically connected to the data receiving circuit board and the data sending circuit board respectively through the accommodation box 10.

[0064] Figure 2 It is a schematic structural diagram of a fixing structure provided by an embodiment of the present utility model. As Figure 2 shown, the fixing structure 13 includes a card slot 131, a movable plate 132, and an elastic member 133.

[0065] One end of the elastic member 133 is fixed in the card slot 131, and the other end of the elastic member 133 is connected to the movable plate 132; the extending direction of the movable plate 132 is parallel to the extending direction of the card slot 131; the movable plate 132 moves along a first direction (i.e., Figure 2 the up and down direction in Figure 2 ), under the action of an external force or the elastic member 133, wherein the first direction is perpendicular to the insertion direction of the circuit board 32 (i.e.,

[0066] the left and right direction in

[0067] It can be understood that when the circuit board 32 is not inserted into the gap between the movable plate 132 and the card slot 131, the elastic member 133 is not squeezed (in a relaxed state), and the gap between the movable plate 132 and the card slot 131 is small; after the circuit board 32 is inserted into the gap between the movable plate 132 and the card slot 131, the elastic member 133 is squeezed, and the movable plate 132 fixes the circuit board 32 under the action of the elastic member 133. Figure 2 Optionally, continuing to refer to

[0068] In a possible implementation, the display circuit 21 includes a display screen and related circuits, and the gas pressure can be directly displayed on the display screen.

[0069] In another possible implementation, Figure 3 is a circuit structure diagram of a display circuit provided by an embodiment of the present invention. As Figure 3 shown, the display circuit (as shown by the part within the dashed box in Figure 3 ) includes a first resistor R1, a second resistor R2, a third resistor R3, and a light-emitting diode VL.

[0070] The first output terminal of the power supply unit 31 is connected to the first pin of the pressure sensor 22. The second pin of the pressure sensor 22 is connected to one end of the first resistor R1. The other end of the first resistor R1 is connected to one end of the second resistor R2 and one end of the third resistor R3. The other end of the second resistor R2 is connected to the positive electrode of the light-emitting diode VL. The negative electrode of the light-emitting diode VL, the other end of the third resistor R3, and the third pin of the pressure sensor 22 are all connected to the second output terminal of the power supply unit 31; the first input terminal and the second input terminal of the power supply unit 31 are connected to an external power supply.

[0071] Optionally, the external power supply can be a 220V AC power supply.

[0072] Optionally, the resistance value of the first resistor R1 is 10 kΩ, the resistance value of the second resistor R2 is 7 kΩ, and the resistance value of the third resistor R3 is 1 kΩ.

[0073] Assume that the normal air pressure of the inert gas is 0.5 MPa. Figure 3 The working principle of the shown display circuit is as follows: After the power supply unit 31 is powered on, it outputs a stable 12V DC voltage. When there is no leakage of the inert gas in the accommodation box 10 (i.e., the air pressure of the inert gas is about 0.5 MPa), the voltage signal output by the second pin of the pressure sensor 22 is relatively large, and at this time, the light-emitting diode VL is in the lit state; when there is a leakage of the inert gas in the accommodation box 10 (i.e., the air pressure of the inert gas is less than about 0.5 MPa), the voltage signal output by the second pin of the pressure sensor 22 is relatively small. After being divided by the first resistor R1 and the second resistor R2, and the voltage is reduced and the current is limited by the third resistor R3, the voltage entering the light-emitting diode VL is lower than the starting voltage of the light-emitting diode VL, and the light-emitting diode VL does not emit light. Thus, it prompts the operation and maintenance personnel to replenish the gas in a timely manner.

[0074] In yet another possible implementation, the number of the display circuits 21 can be at least two. When the number of the display circuits 21 is two, the resistance value of the first resistor of one display circuit 21 is not equal to the resistance value of the first resistor of the other display circuit 21.

[0075] Exemplarily, Figure 4It is the circuit structure diagram of another display circuit provided by the embodiment of the present utility model. As Figure 4 shown, the display circuit (the part shown by the dotted line box in Figure 4 ) includes two first resistors R1, two second resistors R2, two third resistors R3 and two light-emitting diodes VL.

[0076] The first output terminal of the power supply unit 31 is connected to the first pin of the pressure sensor 22. The second pin of the pressure sensor 22 is connected to one end of the first resistor R1. The other end of the first resistor R1 is connected to one end of the second resistor R2 and one end of the third resistor R3. The other end of the second resistor R2 is connected to the positive electrode of the light-emitting diode VL. The negative electrode of the light-emitting diode VL, the other end of the third resistor R3 and the third pin of the pressure sensor 22 are all connected to the second output terminal of the power supply unit 31. The first input terminal and the second input terminal of the power supply unit 31 are connected to an external power supply.

[0077] Optionally, the external power supply can be an AC power supply of 220V.

[0078] Optionally, the resistance value of one first resistor R1 is 10 kΩ, the resistance value of the other first resistor R1 is 5 kΩ, the resistance values of the two second resistors R2 are both 7 kΩ, and the resistance values of the two third resistors R3 are both 1 kΩ.

[0079] Figure 4 The working principle of the shown display circuit is similar to that of the above Figure 3 shown display circuit. Different from the Figure 3 shown display circuit, since the resistance values of the first resistors of the two display circuits 21 are not equal, the voltages entering the two light-emitting diodes VL at the same moment are not equal, resulting in different air pressure magnitudes of the inert gas corresponding to the two light-emitting diodes VL when changing from emitting light to not emitting light. Therefore, two-stage alarm can be realized. That is, when there is no leakage of the inert gas in the accommodation box 10, both light-emitting diodes VL emit light; when there is a slight leakage of the inert gas in the accommodation box 10 (i.e., lower than the first threshold but higher than the second threshold), one light-emitting diode VL emits light and one light-emitting diode VL does not emit light; when there is a serious leakage of the inert gas in the accommodation box 10 (i.e., lower than the second threshold), both light-emitting diodes VL do not emit light.

[0080] In one embodiment, the model of the pressure sensor 22 is PCM300.

The protection component includes a display circuit, a pressure sensor, and a valve; the transmission component includes a power supply unit and at least two circuit boards.
