It should be understood that the data thus used can be interchanged, where appropriate, so that the embodiments of the present application described herein can be carried out in sequences other than those illustrated or described herein. Moreover, the terms "comprise" and "have", and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or apparatus that comprises a list of steps or units is not necessarily limited to those steps or units that are clearly listed, but can include other steps or units that are not clearly listed or inherent to such processes, methods, products, or apparatuses.

[0040] Fig. 1 is a structural schematic diagram of a multi-source heterogeneous data transmission device provided by an embodiment of the present application. As shown in Fig. 1, the multi-source heterogeneous data transmission device comprises a containing box 10, and a transmission assembly arranged in the containing box 10 and a protection assembly arranged outside the containing box 10.

[0041] The containing box 10 comprises a box body and a box door (not shown in Fig. 1) that are opposite to each other and are rotatably connected by a hinge (such as a hinge), so that an operation and maintenance personnel can open / close the containing box 10 through the box door.

[0042] A sealing rubber 12 is arranged between the box body and the box door, and the sealing rubber 12 is arranged to improve the air tightness of the containing box 10, so as to ensure that the inside of the containing box 10 is in a closed state after the box door is closed.

[0043] Optionally, a handle can be arranged on the box door to facilitate the opening / closing of the box door.

[0044] Optionally, a plurality of pairs of threaded holes 11 are arranged on the side of the box door and the box body away from the hinge (if a handle is arranged on the box door, the side is the side close to the handle), so that the operation and maintenance personnel can tighten the box body and the box door by bolts after the box door is closed, thereby further improving the air tightness of the containing box 10.

[0045] The protection assembly comprises a display circuit 21, a pressure sensor 22, and a valve 23.

[0046] The inside of the containing box 10 is in a closed state, the valve 23 is in communication with the inside of the containing box 10, for example, a hole is arranged on the containing box 10, a connecting pipe is welded in the hole, and the valve 23 is in communication with the connecting pipe. The valve 23 is arranged to add inert gas to the inside of the containing box 10.

[0047] The pressure sensor 22 is electrically connected with the display circuit 21. The pressure sensor 22 is in communication with the inside of the containing box 10. For example, a hole is formed on the containing box 10, and a connecting pipe 24 is welded in the hole. One end of the pressure sensor 22 is in communication with the connecting pipe 24. The pressure sensor 22 is arranged to detect the gas pressure in the inside of the containing box 10. The display circuit 21 is arranged to display according to the gas pressure.

[0048] Since the inside of the containing box 10 is in a closed state, the valve 23 can add inert gas to the inside of the containing box 10. Therefore, 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 of the containing box 10 are improved. At the same time, the pressure sensor 22 can detect the gas pressure in the inside of the containing box 10, and the display circuit 21 can display according to the gas pressure. Therefore, the gas pressure of the inert gas is monitored, and the operation and maintenance personnel can supplement the inert gas in time when the gas pressure of the inert gas is too low.

[0049] Optionally, the display circuit 21 can be arranged in the protective box 25 of the containing box 10. Therefore, the protective box 25 can protect the display circuit 21, and the display circuit 21 is not exposed to the external environment.

[0050] The inert gas is also called noble gas, which has very stable chemical properties, and is 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) and radon (Rn).

[0051] Preferably, the inert gas includes sulfur hexafluoride and / or nitrogen. Both sulfur hexafluoride and nitrogen have high electrical insulation performance, which can effectively prevent current from flowing. In addition, sulfur hexafluoride has better heat conduction capacity than air, which is close to the heat conduction capacity of helium and hydrogen. The insulation strength of sulfur hexafluoride 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.

[0052] The transmission assembly includes a power supply unit 31 and at least two circuit boards 32 (one circuit board 32 is shown in FIG. 1). The power supply unit 31 supplies power to each circuit board 32, the pressure sensor 22 and the display circuit 21, thereby ensuring the normal operation of the multi-source heterogeneous data transmission device.

[0053] The inner wall of the accommodating box 10 is provided with at least two pairs of fixing structures 13, and one pair of fixing structures 13 is arranged to fix one circuit board 32; and the at least two circuit boards 32 are arranged to transmit multi-source heterogeneous data. As shown in FIG. 1, one pair of fixing structures 13 is arranged on the left and right side walls of the accommodating box 10 respectively, and the fixing structures 13 and the side walls of the accommodating box 10 are fixed by adhesive / fasteners, so as to ensure that the circuit board 32 is parallel to the horizontal plane.

[0054] Since the present scheme adopts at least two circuit boards 32 to transmit multi-source heterogeneous data, that is, adopts a separate design to transmit data, when a fault occurs, the corresponding circuit board 32 can be replaced, thereby avoiding the problem that when an integrated circuit board fails, the entire circuit board needs to be replaced, and the maintenance cost is reduced. Meanwhile, the circuit board 32 and the fixing structure 13 do not need to be fixed by bolts, which is convenient for maintenance personnel to disassemble, and the maintenance efficiency is improved.

[0055] In an embodiment, the number of circuit boards 32 is 5;

[0056] The five 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.

[0057] Specifically, the data receiving circuit board can receive multi-source heterogeneous data in a wireless or wired manner, and send the multi-source heterogeneous data to the data processing circuit board. Optionally, the data receiving circuit board can support a priority marking function of data.

[0058] The data processing circuit board can process the multi-source heterogeneous data (for example, if the data receiving circuit board marks the priority of data, the data processing circuit board can also sort the multi-source heterogeneous data according to the priority, so as to ensure that the key data can be processed preferentially), such as format conversion, encryption, etc.

[0059] The data storage circuit board can store the multi-source heterogeneous data, that is, provides a buffering function for the multi-source heterogeneous data, and ensures the continuity and stability of data transmission. Optionally, the data storage circuit board can support a quick retrieval and access function of data.

[0060] The data sending circuit board can send the processed multi-source heterogeneous data to a target device.

[0061] The control circuit board is arranged 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 state of each circuit board, and ensure the stability and safety of the multi-source heterogeneous data transmission device.

[0062] Further, the data receiving circuit board and the data sending circuit board can have or not have an antenna. When the data receiving circuit board and the data sending circuit board do not have an antenna, the transmission assembly further comprises an antenna 33. The antenna 33 is arranged outside the accommodating box 10 and is electrically connected with the data receiving circuit board and the data sending circuit board through the accommodating box 10.

[0063] Fig. 2 is a structural schematic diagram of a fixing structure according to an embodiment of the present application. As shown in Fig. 2, the fixing structure 13 comprises a clamping groove 131, a movable plate 132 and an elastic member 133.

[0064] One end of the elastic member 133 is fixed in the clamping groove 131, and the other end of the elastic member 133 is connected with the movable plate 132. The extending direction of the movable plate 132 is parallel to the extending direction of the clamping groove 131. The movable plate 132 moves along a first direction (i.e. the up-down direction in Fig. 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. the left-right direction in Fig. 2).

[0065] It can be understood that when the circuit board 32 is not inserted into the gap between the movable plate 132 and the clamping groove 131, the elastic member 133 is not compressed (in a relaxed state), and the gap between the movable plate 132 and the clamping groove 131 is small. After the circuit board 32 is inserted into the gap between the movable plate 132 and the clamping groove 131, the elastic member 133 is compressed, and the movable plate 132 fixes the circuit board 32 under the action of the elastic member 133.

[0066] Optionally, continuing to refer to Fig. 2, a guide member 134 is arranged on the side of the movable plate 132 close to the slot of the clamping groove 131. The guide member 134 is arranged to guide the circuit board 32 to be inserted into the gap between the movable plate 132 and the clamping groove 131.

[0067] In a possible implementation, the display circuit 21 comprises a display screen and related circuits, and the gas pressure can be directly displayed on the display screen.

[0068] In another possible implementation, Fig. 3 is a circuit structure diagram of a display circuit according to an embodiment of the present application. As shown in Fig. 3, the display circuit (the part shown in the dashed line box in Fig. 3) comprises a first resistor R1, a second resistor R2, a third resistor R3 and a light-emitting diode VL.

[0069] The first output end of the power supply unit 31 is connected with the first pin of the pressure sensor 22, the second pin of the pressure sensor 22 is connected with one end of the first resistor R1, and the other end of the first resistor R1 is connected with 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 with the positive electrode of the light-emitting diode VL, and 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 with the second output end of the power supply unit 31; the first input end and the second input end of the power supply unit 31 are connected with an external power supply.

[0070] Optionally, the external power supply can be a 220V alternating current power supply.

[0071] Optionally, the resistance value of the first resistor R1 is 10 kilo-ohms, the resistance value of the second resistor R2 is 7 kilo-ohms, and the resistance value of the third resistor R3 is 1 kilo-ohm.

[0072] Supposing that the normal pressure of the inert gas is 0.5MPa, the working principle of the display circuit shown in FIG. 3 is as follows: the power supply unit 31 outputs stable 12V direct current after being powered, when the inert gas in the containing box 10 does not leak (i.e. the pressure of the inert gas is about 0.5MPa), the voltage signal output by the second pin of the pressure sensor 22 is relatively large, at this time, the light-emitting diode VL is in the lighting state; when the inert gas in the containing box 10 leaks (i.e. the pressure of the inert gas is less than about 0.5MPa), 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, the voltage entering the light-emitting diode VL is lower than the starting voltage of the light-emitting diode VL due to the voltage reduction and current limitation of the third resistor R3, and the light-emitting diode VL does not emit light. Thus, the operation and maintenance personnel can be prompted to supplement the gas in time.

[0073] In another possible implementation manner, 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.

[0074] For example, FIG. 4 is a circuit structure diagram of another display circuit provided by the embodiment of the application. As shown in FIG. 4, the display circuit (the part shown in the dashed box in FIG. 4) includes two first resistors R1, two second resistors R2, two third resistors R3 and two light-emitting diodes VL.

[0075] The first output end of the power supply unit 31 is connected with the first pin of the pressure sensor 22, the second pin of the pressure sensor 22 is connected with one end of the first resistor R1, and the other end of the first resistor R1 is connected with 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 with 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 with the second output end of the power supply unit 31; the first input end and the second input end of the power supply unit 31 are connected with an external power source.

[0076] Optionally, the external power source can be a 220V alternating current power source.

[0077] Optionally, the resistance value of one first resistor R1 is 10 kilo-ohms, the resistance value of the other first resistor R1 is 5 kilo-ohms, the resistance value of the two second resistors R2 is 7 kilo-ohms, and the resistance value of the two third resistors R3 is 1 kilo-ohm.

[0078] The working principle of the display circuit shown in Fig. 4 is similar to that of the display circuit shown in Fig. 3. Different from the display circuit shown in Fig. 3, because the resistance values of the first resistors of the two display circuits 21 are not equal, the voltage entering the two light-emitting diodes VL at the same time is not equal, thus the gas pressure of the inert gas corresponding to the change of the two light-emitting diodes VL from emitting light to not emitting light is not the same, and thus two-stage alarm can be realized. That is, when the inert gas in the containing box 10 does not leak, both of the light-emitting diodes VL emit light; when the inert gas in the containing box 10 leaks slightly (i.e. lower than the first threshold value but higher than the second threshold value), one light-emitting diode VL emits light and the other light-emitting diode VL does not emit light; when the inert gas in the containing box 10 leaks seriously (i.e. lower than the second threshold value), both of the light-emitting diodes VL do not emit light.

[0079] In an embodiment, the model of the pressure sensor 22 is PCM300.
