[0003] In the prior art, the detection is usually to connect a transmission line to a detector, give an analog signal through the detector, and determine whether the IO channel is faulty by detecting whether the detection controller can receive the signal, or output a signal through the device and receive the signal through the detector to detect the IO channel. However, during the actual operation of detection, the line needs to be disconnected from the original device and then connected to the test probe. As a result, even if the line is not faulty after the device is detected, a short-circuit fault caused by poor contact between the line and the device will occur when the line is reinstalled. Moreover, when the detection device detects the line in a hidden corner, due to the fixed length of the wire, it is very difficult for the wiring head to be precisely matched with the device, seriously affecting the detection efficiency. Content of the Utility Model

[0046] The following will describe in detail the specific implementation manners of the embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the embodiments of the present utility model, and are not used to limit the embodiments of the present utility model.

[0047] In the embodiments of the present utility model, unless otherwise stated, the orientation terms such as "upper, lower, left, right" usually refer to the orientation or positional relationship based on the drawings, or the orientation or positional relationship in which the product of the present utility model is usually placed when in use.

[0048] The terms "first", "second", "third", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0049] The terms "parallel", "perpendicular", etc. do not mean that the components are required to be absolutely parallel or perpendicular, but can be slightly inclined. For example, "parallel" only means that its direction is more parallel relative to "perpendicular", and does not mean that the structure must be completely parallel, but can be slightly inclined.

[0050] The terms "horizontal", "vertical", "hanging", etc. do not mean that the components are required to be absolutely horizontal, vertical or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0051] In addition, terms such as "substantially", "basically", etc. are intended to indicate that the relevant content does not require absolute precision, but can have a certain deviation. For example: "substantially equal" does not only mean absolute equality. Since it is difficult to achieve absolute "equality" in actual production and operation processes, there is generally a certain deviation. Therefore, in addition to absolute equality, "substantially equal" also includes the above-mentioned situation of having a certain deviation. Taking this as an example, in other cases, unless otherwise specified, terms such as "substantially", "basically", etc. have meanings similar to the above.

[0052] In the description of the present utility model, it should also be noted that, unless otherwise clearly specified and defined, the terms "arranged", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0054] As Figures 1 - 3 shown, this embodiment provides an integrated IO channel test device, and the integrated IO channel test device includes:

[0055] A housing 1, inside which a circuit board 2 is arranged;

[0056] Two cable winding mechanisms 4, arranged inside the housing 1, respectively used for winding the input cable 10 and winding the output cable 20;

[0057] The input cable 10 and the output cable 20 are respectively wound on the corresponding cable winding mechanisms 4. The fixed ends of the input cable 10 and the output cable 20 are connected to the circuit board 2, and the connection ends of the input cable 10 and the connection ends of the output cable 20 pass through the housing 1 and are externally connected to the terminal clamp 3;

[0058] A cable limiting mechanism 5, arranged inside the housing 1, used for limiting the input cable 10 and the output cable 20, so that the lengths of the input cable 10 and the output cable 20 extending out of the housing 1 remain unchanged.

[0059] Specifically, in this embodiment, the housing 1 can be set as a square structure with an internal accommodation space. The circuit board 2 is arranged in the internal accommodation space. The input cable 10 and the output cable 20 connected to the circuit board 2 pass through the housing 1 and are connected with a terminal clamp 3, and are connected to the device under test through the terminal clamp 3. By arranging the terminal clamp 3 at the connection ends of the input cable 10 and the output cable 20, rapid connection and disassembly with the device under test can be achieved, and moreover, the stability of the contact part can be ensured. In addition, due to different test environments, the extended lengths of the input cable 10 and the output cable 20 required are different. Therefore, two cable winding mechanisms 4 are arranged in the housing 1, which are respectively used for winding the input cable 10 and winding the output cable 20. Part of the input cable 10 and part of the output cable 20 are respectively wound on the corresponding cable winding mechanisms 4. The cable winding mechanism 4 can generate a continuous inward winding force. Therefore, a cable limiting mechanism 5 is arranged in the housing 1. When the input cable 10 and the output cable 20 are pulled outwards so that the extended lengths of the input cable 10 and the output cable 20 reach the requirements, the input cable 10 and the output cable 20 are limited by the cable limiting mechanism 5 to keep the extended lengths of the input cable 10 and the output cable 20 unchanged. Correspondingly, a test button is arranged on the housing 1, and the test is started or ended by pressing the test button; the circuit board 2 includes a circuit main board and a signal simulation module, and its specific circuit structure is the prior art known to those skilled in the art and will not be elaborated here.

[0060] Further, as Figure 5 shown, an LED lamp core 31 and a push-button switch 32 are arranged on the terminal clamp 3, and the LED lamp core 31 can be controlled to be lit or extinguished by pressing the push-button switch 32.

[0061] Specifically, in this embodiment, since the device under test is in a dark corner with poor lighting, when wiring, it is impossible to accurately and quickly clamp on the interface or pin of the device. Therefore, an LED lamp core 31 and a push-button switch 32 are arranged on the terminal clamp 3. When it is necessary to light the LED lamp core 31, the push-button switch 32 is pressed for lighting, which can greatly improve the installation efficiency and convenience.

[0062] Further, as Figure 1 shown, the cable winding mechanism 4 includes:

[0063] A winding roller 41 rotatably arranged in the housing 1;

[0064] A torsion spring 42 arranged in the winding roller 41 for generating a winding force.

[0065] Specifically, in this embodiment, the winding roller has an annular structure, which can accommodate the cable and is rotatably arranged in the housing 1 through a bearing. At the same time, in order to provide a winding force for the winding roller 41, a torsion spring 42 is arranged on the winding roller 41. The torsion force provided by the torsion spring 42 is used as the winding force of the winding roller 41, so that the winding roller 41 always winds the input cable 10 and the output cable 20.

[0066] In one embodiment, the input cable 10 and the output cable 20 are rotatably connected to the circuit board through an electronic rotary connector or a wire rotary joint (such as a slip ring, etc.) to match the cable rotation brought by the cable winding mechanism 4 for taking in and paying out the cable.

[0067] In another embodiment, the winding roller 41 is arranged to include a first winding roller and a second winding roller connected to each other. The diameter of the first winding roller is larger than that of the second winding roller, and the second winding roller is close to the circuit board. The input cable 10 and the output cable 20 are sequentially connected to the first winding roller and the second winding roller, and a section of cable is reserved between the second winding roller and the circuit board 2. When the input cable 10 or the output cable 20 is pulled outwards, since the diameter of the first winding roller is much larger than that of the second winding roller, the cable pulled out of the housing will already have a longer length, while the length of the cable pulled out on the second winding roller is shorter. Similarly, when the input cable 10 or the output cable 20 is wound inwards, since the diameter of the first winding roller is much larger than that of the second winding roller, the cable wound into the housing will already have a longer length, while the length of the cable wound on the second winding roller is shorter.

[0068] Further, as Figure 4 shown, a limiting groove 101 is vertically arranged on the housing 1;

[0069] The cable limiting mechanism 5 includes:

[0070] A limiting rod 51, which is slidably arranged in the limiting groove 101. The top end of the limiting rod 51 extends out of the limiting groove 101 and is located outside the housing 1. Two limiting holes 511 are arranged on the limiting rod 51, and the input cable 10 and the output cable 20 pass through the corresponding limiting holes 511;

[0071] A spring 52, which is arranged at the bottom end of the limiting groove 101, and the top end of the spring 52 is connected to the bottom end of the limiting rod 51.

[0072] Specifically, in this embodiment, the limiting groove 101 has a certain depth, and a first through hole for the input cable 10 to pass through and a second through hole for the output cable 20 to pass through are arranged on the corresponding side wall of the housing 1. The limiting groove 101 passes through the first through hole and the second through hole. The limiting rod 51 can be arranged as a round rod or a square rod, and the shape of the limiting groove 101 matches that of the limiting rod 51.

[0073] Meanwhile, a limiting rod 51 is slidably arranged in the limiting groove 101. A spring 52 is arranged at the bottom end of the limiting groove 101 below the limiting rod 51. The bottom end of the limiting rod 51 is connected to the top end of the spring 52, so that the spring 52 generates an upward elastic force to give an upward force to the limiting rod 51. In order to realize the limiting and fixing of the input cable 10 and the output cable 20, two limiting holes 511 are arranged on the limiting rod 51. The input cable 10 passes through the corresponding limiting holes 511 and the first through hole, and the output cable 20 respectively passes through the corresponding limiting holes 511 and the second through hole. Meanwhile, under the action of the upward force applied by the spring 52 to the limiting rod 51, the input cable 10 is respectively clamped with the limiting groove 101 of the limiting rod 51 and the first through hole, and the output cable 20 is respectively clamped with the limiting groove 101 of the limiting rod 51 and the second through hole, realizing the limiting of the input cable 10 and the output cable 20, and keeping the extended lengths of the input cable 10 and the output cable 20 unchanged.

[0074] When it is necessary to adjust the extended lengths of the input cable 10 and the output cable 20, by pressing down the limiting rod 51, the first through hole and the second through hole are aligned with the corresponding limiting holes 511 (at the same height). By pulling the input cable 10 and the output cable 20 outwards, the lengths of the input cable 10 and the output cable 20 are extended or the input cable 10 and the output cable 20 are relaxed. By means of the cable winding mechanism 4, the cables are retracted, and the extended lengths of the input cable 10 and the output cable 20 are shortened. After reaching the set requirements, the limiting rod 51 is released, and the clamping of the input cable 10 and the output cable 20 is realized again.

[0075] Furthermore, the inner surface of the limiting hole 511 is arranged in a serrated structure.

[0076] Specifically, in this embodiment, in order to ensure the limiting effect on the cable, the inner surface of the limiting hole 511 is arranged in a serrated structure, so as to increase the contact pressure and improve the limiting effect, and avoid the input cable 10 and the output cable 20 from sliding under the action of the winding force of the cable winding mechanism 4.

[0077] Furthermore, as Figure 1 shown, the integrated IO channel test device further includes:

[0078] Two dust-proof sleeves 6 are arranged on the outer surface of the housing 1. The wiring ends of the input cable 10 and the output cable 20 pass through the corresponding dust-proof sleeves 6 and are externally connected to the wiring clips 3. When the cable winding mechanism 4 tightens the input cable 10 and the output cable 20, the wiring clips 3 are located in the corresponding dust-proof sleeves 6.

[0079] Specifically, in the present embodiment, in order to protect the connection clamp 3, prevent a large area of dust from accumulating on the connection clamp 3 when it is not used for a long time, or prevent it from being wetted by rain, and at the same time prevent the connection clamp 3 from being knocked and causing injury to equipment or personnel, and improve the service life and safety of the connection clamp 3, two dust-proof sleeves 6 are provided on the housing 1. When the cable winding mechanism 4 tightens the input cable 10 and the output cable 20, the connection clamp 3 is located within the corresponding dust-proof sleeve 6. The two dust-proof sleeves 6 can be arranged horizontally and fixed on the housing 1.

[0080] Furthermore, finger grooves 61 are oppositely arranged on each dust-proof sleeve 6.

[0081] Specifically, in the present embodiment, when the cable winding mechanism 4 tightens the input cable 10 and the output cable 20, the connection clamp 3 is located in the internal space of the corresponding dust-proof sleeve 6. In order to facilitate the removal of the connection clamp 3 from the internal space of the dust-proof sleeve 6, finger grooves 61 are oppositely arranged on the side of the dust-proof sleeve 6 to facilitate the removal of the connection clamp 3.

[0082] Furthermore, as Figure 1 shown, the integrated IO channel test device further includes:

[0083] A display screen 7, arranged on the outer surface of the housing 1, and the display screen 7 is connected to the circuit board 2 for displaying the input information and output information of the circuit board 2.

[0084] Specifically, in the present embodiment, by arranging the display screen 7 on the outer surface of the housing 1 and connecting the circuit board 2 to the display screen 7, the input information and output information of the circuit board 2 can be visually displayed to test and judge whether it is normal.

[0085] Furthermore, as Figure 2 shown, the integrated IO channel test device further includes:

[0086] A storage battery 8, arranged inside the housing 1 and connected to the circuit board 2;

[0087] A power output socket 81, arranged on the housing 1 and connected to the output end of the storage battery 8;

[0088] A charging interface 82, arranged on the housing 1 and connected to the input end of the storage battery 8.

[0089] Specifically, in this embodiment, the storage battery 8 is set as a rechargeable battery. While supplying power to the circuit board 2, it can also be used as a mobile power source to supply power to external devices through the power output socket 81, and can be charged through the charging interface 82, improving the convenience of use. Correspondingly, a power on / off control button is provided on the housing 1 to control the power on / off state between the storage battery 8 and the circuit board 2.

[0090] Furthermore, a carrying handle 9 is provided at the top of the housing 1.

[0091] Specifically, in this embodiment, providing a carrying handle 9 at the top of the housing 1 can facilitate the taking and placing of the integrated IO channel test device.

[0092] In a specific embodiment, for the DCS (Distributed Control System) in a thermal power plant, the IO channels (Input / Output Channels) refer to the signal transmission lines connecting the on-site sensors, actuators and the DCS controller, which are used to convert the physical parameters of the on-site equipment (such as temperature, pressure, liquid level, flow rate, etc.) into electrical signals and input them into the controller, and convert the control instructions output by the controller into signals for driving the on-site equipment to act. Ensuring the accuracy and reliability of the IO channels is the key to ensuring the normal operation of the entire DCS system. A specific test method is provided, including:

[0093] For the detection of the input channels, connect the terminal clamp 2 of the output cable 20 of the integrated IO channel test device to the DCS input channel to be tested, ensure that the terminal clamp 3 is tightened, press the test button on the integrated IO channel test device, and start sending analog signals to the DCS input channel through the circuit board 2. The display screen 7 will display the current output signal value and the test status in real time. Observe the numerical change of the corresponding input channel on the DCS controller or the human-machine interface (HMI), and confirm whether it is consistent with the analog signal output by the integrated IO channel test device. If there is a deviation, record and analyze the reason. According to the test plan, gradually change the analog signal value output by the device, repeat the above steps, and verify the response of the DCS input channel under different signal conditions. After completing all test items, stop the DCS output signal, disconnect the connection between the terminal clamp 3 and the DCS output channel, and retract the terminal clamp 3 into the dust-proof sleeve 6.

[0094] For the detection of the output channel, connect the terminal clamp 2 of the input cable 10 of the integrated IO channel test device to the DCS output channel to be tested. Set relevant output instructions through the DCS controller or HMI to make the channel to be tested generate the expected output signal. The integrated IO channel test device starts to receive and display the signal value of the DCS output channel. Observe the signal parameters displayed on the display screen 7 and compare them with the expected output. According to the test plan, adjust the output signal value through the DCS system. The integrated IO channel test device synchronously collects and displays the changed signal to verify the linearity, stability and response speed of the DCS output channel. After completing all test items, stop the DCS output signal, disconnect the connection between the terminal clamp 3 and the DCS output channel, and retract the terminal clamp 3 into the dust-proof sleeve 6.
