Description

Technical Field

[0001] This invention relates to the field of DCS communication equipment, and more particularly to a fault detection device for instrument control DCS communication. Background Technology

[0002] DCS typically adopts a hierarchical structure, with each level consisting of several subsystems. Each subsystem achieves several specific and finite objectives, forming a pyramid structure.

[0003] Existing communication equipment based on instrumentation and control DCS often experiences faults. During fault detection, it is necessary to ensure the stable connection of the connectors of each detection circuit. Due to the complexity of the circuits in DCS communication equipment, short-circuiting is usually used to determine whether components in the circuit are damaged in order to achieve fast detection speed. However, existing fault detection equipment requires precise positioning of the connectors in the circuit during short-circuiting operations, which is done manually. This can easily lead to poor contact or even overheating. Moreover, in cases of severe overheating, it may cause injury or danger. Therefore, a fault detection device based on instrumentation and control DCS communication is designed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a fault detection device based on instrumentation and control DCS communication, which is easy to inspect and has good safety.

[0005] This invention provides a fault detection device based on instrumentation and control DCS communication, comprising:

[0006] The DCS communication circuit has multiple connector holes evenly spaced at the top and bottom of the front side. Each connector hole has a circuit connector mounted on its inner wall. Each circuit connector is electrically connected to a connecting wire. Each connecting wire extends outward through the outer surface of the DCS communication circuit. Each circuit connector has a detection groove on its front side.

[0007] A current detector is provided, with a display screen embedded on its front side and an adjustment knob also mounted on the front side. Two symmetrical sockets are opened at the bottom of the current detector, and plugs are inserted into the inner walls of the two sockets. A detection line is fixedly connected to the bottom end of the plug, and a detection connector is mounted at the other end of the detection line. A detection clip is mounted at the end of the detection connector, and the detection connector and the detection clip are respectively fitted to the inner wall of one of the connector holes and the detection groove. The detection connector is equipped with a fastening mechanism.

[0008] Preferably, the end of the detection connector is provided with a fixing groove, the end of the detection line passes through the detection connector and is electrically connected to a metal detection piece, the metal detection piece is fixedly connected to the inner wall of the fixing groove, and the detection card block is fixedly connected to the bottom end of the metal detection piece.

[0009] Preferably, the fastening mechanism includes a fixed collar, which is fixedly installed at the end of the detection connector. There is an annular cavity between the fixed collar and the detection connector. A movable collar is slidably connected to the inner wall of the annular cavity. Three positioning grooves are formed on the inner wall of the annular cavity, and the three positioning grooves are arranged in a circular array. A positioning slider is slidably connected to the inner wall of each of the three positioning grooves. A positioning spring is fixedly connected between the outer surface of the positioning slider and the inner wall of the positioning groove.

[0010] Preferably, the inner wall of the annular cavity is further provided with three fastening grooves, the three fastening grooves are respectively located below the three positioning grooves, and the three fastening grooves are all connected to the joint hole. Fastening blocks are slidably connected on the inner wall of the fastening grooves, and the ends of the three fastening blocks are tightly fitted to the inner wall of the joint hole.

[0011] Preferably, the outer surfaces of the three fastening blocks are provided with inclined extrusion grooves, the ends of the movable collar are fixedly connected to the three extrusion blocks, the ends of the extrusion blocks are provided with inclined surfaces, and the inclined surfaces are in close contact with the inner walls of the inclined extrusion grooves, and the movable collar is also equipped with a moving component.

[0012] Preferably, the moving component includes a moving sleeve that fits against the outer surface of the fixed collar and is fixedly connected to the end of the movable collar. The moving sleeve is movably sleeved on the outer surface of the detection line. Two fixing blocks are symmetrically fixedly connected to the outer surface of the fixed collar, and the outer surface of the moving sleeve fits against the two fixing blocks.

[0013] Preferably, the moving component further includes two moving slots, which are respectively opened inside two fixed blocks. A fixed shaft is fixedly connected to the inner wall of the moving slot, and a transmission gear is movably sleeved on the outer circular surface of the fixed shaft. A first rack and a second rack are respectively meshed on both sides of the transmission gear, and the first rack and the second rack are slidably connected to the inner wall of the moving slot.

[0014] Preferably, the outer wall of the other side of the first rack is fixedly connected to the outer circular surface of the movable sleeve, and the end of the second rack extends outward through the outer surface of the fixed block and is fixedly connected to the movable block.

[0015] Compared with the prior art, the fault detection device for instrument control DCS communication of the present invention has the following beneficial effects:

[0016] 1. This fault detection device based on DCS communication for instrument control, during short-circuit operation, first inserts the two plugs at the ends of the two detection lines into the two sockets at the bottom of the current detector, and then inserts the two detection connectors at the other ends of the two detection lines into the two connector holes. Then, rotate the detection connectors to adjust their positions so that the detection clips at the ends of the detection connectors can be inserted into the detection slots on the circuit connectors. At this time, a loop is formed between the two detection lines and the two circuit connectors. The current value is then displayed on the screen of the current detector, thereby enabling fault detection of the circuit connecting the two circuit connectors.

[0017] 2. This fault detection device based on DCS communication uses a fastening mechanism to insert the detection connector into the connector hole and allow the detection card block to be inserted into the detection slot on the circuit connector. When the movable collar is released, the three compressed positioning springs rebound, pushing the three positioning sliders to slide in the three positioning grooves respectively. This causes the movable collar to move towards the three fastening blocks, making the inclined surface of the pressing block's end fit tightly against the inner wall of the inclined pressing groove. This pushes the three fastening blocks outward, making the ends of the three fastening blocks fit tightly against the inner wall of the connector hole. Under the action of friction, the positions of the three fastening blocks are fixed, thereby fixing the positions of the detection connector and the detection card block. This ensures that during fault detection, the detection card block will not detach from the detection slot on the circuit connector, and the detection card block is accurately positioned on the circuit connector, preventing poor contact or even overheating.

[0018] 3. This fault detection device based on DCS communication uses a movable component. When the position of the movable collar needs to be moved, pressing two movable blocks causes them to move towards two fixed blocks, which in turn pushes the second rack to slide into the movable groove. Since the first and second racks are meshed on both sides of the transmission gear, the transmission gear rotates. At the same time, the transmission gear drives the first and second racks to slide in opposite directions. When the two first racks slide simultaneously, the movable sleeve moves outward, which in turn moves the movable collar. Attached Figure Description

[0030] To further understand the present invention, embodiments of the present invention are described below in conjunction with examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, and not for limiting the present invention.

[0031] Example 1

[0032] This invention discloses a fault detection device based on DCS communication.

[0033] Please refer to the appendix. Figure 1-4 ,include:

[0034] DCS communication circuit 1 has multiple connector holes 101 evenly spaced at the top and bottom of the front side of DCS communication circuit 1. Circuit connectors 102 are installed on the inner walls of the multiple connector holes 101. The multiple circuit connectors 102 are electrically connected to connecting wires 103. The multiple connecting wires 103 extend outward through the outer surface of DCS communication circuit 1. Detection grooves 104 are opened on the front side of the multiple circuit connectors 102.

[0035] The current detector 2 has a display screen 201 embedded on its front side and an adjustment knob 202 mounted on its front side. Two symmetrical sockets 203 are opened at the bottom of the current detector 2. A plug 204 is inserted into the inner wall of each socket 203. A detection line 205 is fixedly connected to the bottom of the plug 204. A detection connector 206 is mounted at the other end of the detection line 205. A detection clip 207 is mounted at the end of the detection connector 206. The detection connector 206 and the detection clip 207 are respectively attached to the inner wall of one of the connector holes 101 and the detection groove 104. The detection connector 206 is equipped with a fastening mechanism.

[0036] The end of the test connector 206 is provided with a fixing groove 208. The end of the test line 205 passes through the test connector 206 and is electrically connected to a metal detection piece 209. The metal detection piece 209 is fixedly connected to the inner wall of the fixing groove 208, and the test card block 207 is fixedly connected to the bottom end of the metal detection piece 209. The current in the circuit connector 102 can be transmitted to the test line 205 through the test card block 207 and the metal detection piece 209 by the metal detection piece 209.

[0037] Working principle: When a fault occurs in DCS communication circuit 1 during use, the current detector 2 is used to short-circuit the circuit to determine whether the components in DCS communication circuit 1 are damaged.

[0038] During the short-circuit operation, firstly, insert the two plugs 204 at the ends of the two test wires 205 into the two sockets 203 at the bottom of the current detector 2, and then insert the two test connectors 206 at the other ends of the two test wires 205 into the two connector holes 101. Then, rotate the test connectors 206 to adjust their position so that the test clips 207 at the ends of the test connectors 206 can be inserted into the test slots 104 on the circuit connectors 102. At this time, a circuit is formed between the two test wires 205 and the two circuit connectors 102. Then, the current value is displayed on the display screen 201 on the current detector 2, thereby enabling fault detection of the circuit connecting the two circuit connectors 102.

[0039] Example 2:

[0040] This invention discloses a fault detection device based on DCS communication.

[0041] Please refer to the appendix. Figure 1-4 ,include:

[0042] DCS communication circuit 1 has multiple connector holes 101 evenly spaced at the top and bottom of the front side of DCS communication circuit 1. Circuit connectors 102 are installed on the inner walls of the multiple connector holes 101. The multiple circuit connectors 102 are electrically connected to connecting wires 103. The multiple connecting wires 103 extend outward through the outer surface of DCS communication circuit 1. Detection grooves 104 are opened on the front side of the multiple circuit connectors 102.

[0043] The current detector 2 has a display screen 201 embedded on its front side and an adjustment knob 202 mounted on its front side. Two symmetrical holes 203 are opened at the bottom of the current detector 2. A plug 204 is inserted into the inner wall of each of the two holes 203. A detection line 205 is fixedly connected to the bottom of the plug 204. A detection connector 206 is mounted at the other end of the detection line 205. A detection card 207 is mounted at the end of the detection connector 206. The detection connector 206 and the detection card 207 are respectively attached to the inner wall of one of the connector holes 101 and the detection groove 104. The detection connector 206 is equipped with a fastening mechanism.

[0044] The detection connector 206 is inserted into the connector hole 101 via the fastening mechanism, allowing the detection block 207 to be inserted into the detection groove 104 on the circuit connector 102. At this point, the movable collar 302 is released, and the three compressed positioning springs 305 rebound, pushing the three positioning sliders 304 to slide in the three positioning grooves 303 respectively. This causes the movable collar 302 to move towards the three fastening blocks 307, ensuring that the inclined surface at the end of the pressing block 308 is tightly fitted against the inner wall of the inclined pressing groove 309. This pushes the three fastening blocks 307 outward, so that the ends of the three fastening blocks 307 are tightly fitted with the inner wall of the connector hole 101. Under the action of friction, the position of the three fastening blocks 307 is fixed, thereby fixing the position of the detection connector 206 and the detection card block 207. This ensures that during the fault detection process, the detection card block 207 will not detach from the detection slot 104 on the circuit connector 102. The detection card block 207 is accurately positioned on the circuit connector 102, preventing poor contact or even overheating.

[0045] Please refer to the appendix. Figure 5-6The fastening mechanism includes a fixed collar 3, which is fixedly installed at the end of the detection connector 206. There is an annular cavity 301 between the fixed collar 3 and the detection connector 206. A movable collar 302 is slidably connected to the inner wall of the annular cavity 301. Three positioning grooves 303 are provided on the inner wall of the annular cavity 301, and the three positioning grooves 303 are arranged in a circular array. Positioning sliders 304 are slidably connected to the inner walls of the three positioning grooves 303. A positioning spring 305 is fixedly connected between the outer surface of the positioning slider 304 and the inner wall of the positioning groove 303.

[0046] Please refer to the appendix. Figure 6 The inner wall of the annular cavity 301 is also provided with three fastening grooves 306. The three fastening grooves 306 are respectively located below the three positioning grooves 303, and the three fastening grooves 306 are all connected to the connector hole 101. Fastening blocks 307 are slidably connected on the inner wall of the fastening grooves 306. The ends of the three fastening blocks 307 are all tightly fitted with the inner wall of the connector hole 101. The lower surface of the ends of the three fastening blocks 307 are all set as arc-shaped, so that when the detection connector 206 is inserted into the connector hole 101, the three fastening blocks 307 can be pushed into the three fastening grooves 306 without affecting the insertion of the detection connector 206 into the connector hole 101.

[0047] Please refer to the appendix. Figure 7 The outer surfaces of the three fastening blocks 307 are all provided with inclined extrusion grooves 309. The ends of the movable collar 302 are fixedly connected to three extrusion blocks 308. The ends of the extrusion blocks 308 are opened with bevels, and the bevels are closely fitted with the inner walls of the inclined extrusion grooves 309. The movable collar 302 is also equipped with a moving component.

[0048] Working principle: Before inserting the test connector 206 into the connector hole 101, the movable collar 302 is first pulled outward by the moving component, causing the movable collar 302 to slide in the annular cavity 301. This causes the three positioning sliders 304 to slide in the three positioning grooves 303 respectively, compressing the three positioning springs 305. This also causes the pressing block 308 at the end of the movable collar 302 to move, so that the three pressing blocks 308 no longer press the pressing groove 309 on the outer surface of the fastening block 307. Moreover, the lower surface of the end of the three fastening blocks 307 is set as arc, so that when the test connector 206 is inserted into the connector hole 101, the three fastening blocks 307 can be pushed into the three fastening grooves 306 without affecting the insertion of the test connector 206 into the connector hole 101. At this time, the test connector 206 can be inserted into the connector hole 101, and the test card 207 can be inserted into the test groove 104 on the circuit connector 102.

[0049] At this time, the movable collar 302 is released, and the three compressed positioning springs 305 rebound, pushing the three positioning sliders 304 to slide in the three positioning grooves 303 respectively. This causes the movable collar 302 to move towards the three fastening blocks 307, so that the inclined surface at the end of the extrusion block 308 fits tightly against the inner wall of the inclined extrusion groove 309, and pushes the three fastening blocks 307 outward, so that the ends of the three fastening blocks 307 fit tightly against the inner wall of the connector hole 101. Under the action of friction, the position of the three fastening blocks 307 is fixed, thereby fixing the position of the detection connector 206 and the detection card block 207. This ensures that during the fault detection process, the detection card block 207 will not detach from the detection groove 104 on the circuit connector 102. The detection card block 207 is accurately positioned on the circuit connector 102, preventing poor contact or even overheating.

[0050] After the test is completed, the movable collar 302 is pulled upward again by the moving component, which causes the pressing block 308 at the end of the movable collar 302 to move as well. This causes the three pressing blocks 308 to stop pressing the pressing groove 309 on the outer surface of the fastening block 307, and the ends of the three fastening blocks 307 to stop pressing the inner wall of the connector hole 101. At this time, the test connector 206 and the test card block 207 can be taken out.

[0051] Example 3:

[0052] This invention discloses a fault detection device based on DCS communication.

[0053] Please refer to the appendix. Figure 1-4 ,include:

[0054] DCS communication circuit 1 has multiple connector holes 101 evenly spaced at the top and bottom of the front side of DCS communication circuit 1. Circuit connectors 102 are installed on the inner walls of the multiple connector holes 101. The multiple circuit connectors 102 are electrically connected to connecting wires 103. The multiple connecting wires 103 extend outward through the outer surface of DCS communication circuit 1. Detection grooves 104 are opened on the front side of the multiple circuit connectors 102.

[0055] The current detector 2 has a display screen 201 embedded on its front side and an adjustment knob 202 mounted on its front side. Two symmetrical sockets 203 are opened at the bottom of the current detector 2. A plug 204 is inserted into the inner wall of each socket 203. A detection line 205 is fixedly connected to the bottom of the plug 204. A detection connector 206 is mounted at the other end of the detection line 205. A detection clip 207 is mounted at the end of the detection connector 206. The detection connector 206 and the detection clip 207 are respectively attached to the inner wall of one of the connector holes 101 and the detection groove 104. The detection connector 206 is equipped with a fastening mechanism.

[0056] Please refer to the appendix. Figure 8-10 The movable collar 302 is also equipped with a moving component, which includes a movable sleeve 4. The movable sleeve 4 is in contact with the outer surface of the fixed collar 3, and the movable sleeve 4 is fixedly connected to the end of the movable collar 302. The movable sleeve 4 is movably sleeved on the outer surface of the detection line 205. Two fixing blocks 401 are symmetrically fixedly connected to the outer surface of the fixed collar 3, and the outer surface of the movable sleeve 4 is in contact with the two fixing blocks 401.

[0057] When the movable collar 302 needs to be moved, the two movable blocks 406 are pressed, causing them to move toward the two fixed blocks 401 respectively. This pushes the second rack 405 to slide into the movable groove 402. Since the first rack 404 and the second rack 405 are meshed on both sides of the transmission gear 403, the transmission gear 403 is rotated. At the same time, the transmission gear 403 drives the first rack 404 and the second rack 405 to slide in opposite directions. When the two first racks 404 slide at the same time, the movable sleeve 4 can be moved outward, thereby moving the movable collar 302.

[0058] Please refer to the appendix. Figure 9-10 The movable component also includes two movable slots 402, which are respectively opened inside the two fixed blocks 401. A fixed shaft is fixedly connected to the inner wall of the movable slot 402, and a transmission gear 403 is movably sleeved on the outer circular surface of the fixed shaft. A first rack 404 and a second rack 405 are respectively meshed on both sides of the transmission gear 403, and the first rack 404 and the second rack 405 are slidably connected to the inner wall of the movable slot 402.

[0059] Please refer to the appendix. Figure 10 The outer wall of the first rack 404 is fixedly connected to the outer circular surface of the movable sleeve 4, and the end of the second rack 405 extends outward through the outer surface of the fixed block 401 and is fixedly connected to the movable block 406.

[0060] Working principle: During use, when it is necessary to move the position of the movable collar 302, press the two movable blocks 406, so that the two movable blocks 406 move toward the two fixed blocks 401 respectively, thereby pushing the second rack 405 to slide into the moving groove 402. Since the transmission gear 403 is meshed with the first rack 404 and the second rack 405 on both sides respectively, the transmission gear 403 is driven to rotate. At the same time, the transmission gear 403 drives the first rack 404 and the second rack 405 to slide in opposite directions. When the two first racks 404 slide at the same time, the moving sleeve 4 can be driven to move outward, thereby driving the movable collar 302 to move.

[0061] Furthermore, the movable sleeve 4 can only move outward when both first racks 404 slide simultaneously, thus avoiding accidental contact with one of the movable blocks 406, which would cause the movable sleeve 4 to move outward.

[0062] In summary: When a fault occurs in the DCS communication circuit 1 during use, the current detector 2 is used to short-circuit to determine whether the components in the circuit of the DCS communication circuit 1 are damaged. In the short-circuit operation, first insert the two plugs 204 at the ends of the two detection lines 205 into the two sockets 203 at the bottom of the current detector 2 respectively.

[0063] Before inserting the test connector 206 into the connector hole 101, press the two movable blocks 406 to move them toward the two fixed blocks 401, which in turn pushes the second rack 405 to slide into the moving groove 402. Since the first rack 404 and the second rack 405 are meshed on both sides of the transmission gear 403, the transmission gear 403 is rotated. At the same time, the transmission gear 403 drives the first rack 404 and the second rack 405 to slide in opposite directions. When the two first racks 404 slide at the same time, the moving sleeve 4 can be moved outward, which in turn drives the movable collar 302 to move.

[0064] When the movable collar 302 slides in the annular cavity 301, the three positioning sliders 304 slide in the three positioning grooves 303 respectively, compressing the three positioning springs 305, and driving the pressing block 308 at the end of the movable collar 302 to move as well, so that the three pressing blocks 308 no longer press the pressing groove 309 on the outer surface of the fastening block 307, and the lower surface of the end of the three fastening blocks 307 is set as arc, so that when the detection connector 206 is inserted into the connector hole 101, the three fastening blocks 307 can be pushed into the three fastening grooves 306, without affecting the insertion of the detection connector 206 into the connector hole 101. At this time, the detection connector 206 can be inserted into the connector hole 101, and the detection card block 207 can be inserted into the detection groove 104 on the circuit connector 102;

[0065] At this time, the movable collar 302 is released, and the three compressed positioning springs 305 rebound, pushing the three positioning sliders 304 to slide in the three positioning grooves 303 respectively. This causes the movable collar 302 to move towards the three fastening blocks 307, so that the inclined surface at the end of the extrusion block 308 fits tightly against the inner wall of the inclined extrusion groove 309, and pushes the three fastening blocks 307 outward, so that the ends of the three fastening blocks 307 fit tightly against the inner wall of the connector hole 101. Under the action of friction, the position of the three fastening blocks 307 is fixed, thereby fixing the position of the detection connector 206 and the detection card block 207. This ensures that during the fault detection process, the detection card block 207 will not detach from the detection groove 104 on the circuit connector 102. The detection card block 207 is accurately positioned on the circuit connector 102, preventing poor contact or even overheating.

[0066] At this time, a loop is formed between the two detection lines 205 and the two circuit connectors 102. The current value is then displayed on the display screen 201 on the current detector 2, so that fault detection can be performed on the circuit connecting the two circuit connectors 102.

[0067] After the test is completed, press the two movable blocks 406 again, so that the two movable blocks 406 move toward the two fixed blocks 401 respectively, thereby pushing the second rack 405 to slide into the moving groove 402. At the same time, the second rack 405 slides in the opposite direction. When the two first racks 404 slide at the same time, the moving sleeve 4 can be driven to move outward, thereby driving the movable collar 302 to move. The pressing block 308 at the end of the movable collar 302 also moves, so that the three pressing blocks 308 no longer press the pressing groove 309 on the outer surface of the fastening block 307, and the ends of the three fastening blocks 307 no longer press the inner wall of the connector hole 101. At this time, the test connector 206 and the test card block 207 can be taken out.
