Description

Technical Field

[0001] The utility model relates to the technical field of bus communication line vehicle auxiliary equipment, and more specifically to the technical field of bus communication line vehicle tooling. Background Art

[0002] A bus-line tooling system is used in the development and commissioning of bus-based communication products (bus-based gas alarm controllers and bus-based gas detectors). Due to the shortcomings of bus communication, such as bus contention and signal interference, and the complexities of commercial and chemical field environments, bus communication system performance can be degraded, data transmission errors can occur, and the system can become unstable. In particular, when the number of detector installation points exceeds 64, field environments often experience communication anomalies such as false alarms, partial communication failures, continuous self-tests, and alternating fault reporting. Therefore, the design of a bus-line tooling system is necessary.

[0003] Defects of existing technology:

[0004] 1. The existing line car tooling adopts the method of using two independent integral combinations of the long line car and the detector tooling car;

[0005] 2. The long-line in-vehicle wiring has only two strands, which can only be used to connect the signal line or the power line of the bus-type gas alarm controller to the gas detector. As a result, the power supply or signal line is directly connected to the detector end, and the power supply and signal lines cannot be connected to the long line at the same time, which is inconsistent with the actual environment.

[0006] 3. The total length of a single-strand cable in a long-line vehicle is 2000m, with each 100m being a basic unit length. The two basic unit lengths are connected using spring-loaded (press-on) terminals for long-line connection, and quick-connect terminals welded to the PCB. However, the spring-loaded terminals often lose their ability to hold down the wiring and become damaged after a period of use. Furthermore, since the PCB is fixed to the vehicle, the reserved operating space is limited. Maintenance requires the PCB to be removed and all wiring disconnected, making maintenance and replacement difficult.

[0007] 4. Existing long-distance vehicles have one node every 100 meters for connecting detectors. When a node is connected to a large number of detectors, the wiring cannot be pressed in or the external pull wire clamp is used, resulting in wiring confusion or pulling on each other. When a node is connected to a small number of detectors, the target connection quantity cannot be met. Connecting multiple detectors to one point means the communication distance from the node to the detector end is 0 meters, which does not meet the on-site usage environment.

[0008] 5. If you want to achieve complex wiring such as fishbone type and star type, you need to manually break each node and connect them according to the wiring requirements, which will also lead to disordered wiring and a chaotic environment around the line car. If the wiring between nodes is too long, it will not be possible to restore the on-site wiring environment.

[0009] 6. With the increasing number of product models, the demand for compatibility, bus communication performance, and long-line capability testing is becoming more and more important. Complex wiring forms are inefficient and difficult to use.

[0010] 7. The existing detector tooling vehicle uses a whole detector and uses one connector for 16 detectors, with 64 detectors in the vehicle, distributed in 8 layers from the inside to the outside. It is bulky and difficult to carry, and cannot achieve on-site distributed wiring. After the detector ages, it is difficult to replace and maintain, and cannot be replaced for compatibility testing. The compatible products are limited. Utility Model Content

[0011] The purpose of this utility model is to solve the above technical problems by providing a bus communication line tooling, which can adjust the wiring form according to actual needs and apply electromagnetic interference and noise interference to the communication circuit to solve the problem that the gas monitoring system cannot work properly due to interference with the field bus.

[0012] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0013] The utility model provides a bus communication line vehicle tooling, comprising a communication line vehicle body and a running mechanism arranged at the bottom of the communication line vehicle body, wherein the communication line vehicle body comprises a shell, a box arranged below the shell, and a detection wiring assembly arranged inside the shell and integrating wiring and detectors;

[0014] The detection wiring assembly includes multiple detector wiring units arranged in parallel, and two adjacent detector wiring units are connected by detachable buckles; each detector wiring unit includes a detector panel and multiple detectors arranged in an array on the detector panel.

[0015] Specifically, detectors are fixed to detector panels, with multiple detectors arrayed on each panel. A single wiring harness assembly houses multiple detector panels, connected by snap-on fasteners for quick installation, removal, compatible replacement, and transport for inspection. The wiring and detectors are integrated, and a travel mechanism at the bottom allows for movement and fixation according to test environment requirements.

[0016] In one embodiment, each detector wiring unit includes a detector panel and sixteen detectors arranged in an array on the detector panel.

[0017] In one embodiment, each detector includes a detector main board, a front-stage module assembly, a detector power supply, and a signal line adapter terminal. The front-stage module assembly, the detector power supply, and the signal line adapter terminal are all installed on the detector main board, and the signal line is connected to the back line branch through the signal line adapter terminal.

[0018] Specifically, the signal line adapter terminal is used for detector and wiring connection.

[0019] In one embodiment, the front-stage module assembly includes a front-stage module base and a front-stage module plugged into the front-stage module base.

[0020] In one embodiment, the traveling mechanism includes at least three movable roller assemblies with brake mechanisms arranged at the bottom of the communication line vehicle body, and all movable roller assemblies are located at the bottom edge of the communication line vehicle body, and all movable roller assemblies are not collinear.

[0021] In one embodiment, the traveling mechanism is four movable rollers with brake mechanisms arranged at the four corners of the bottom of the communication line vehicle body.

[0022] In one embodiment, the box stores the main line and branch lines, which are connected through plug-in terminals for introduction and extraction, and at the same time play a certain role in counterweight and anti-dumping. One end of the long line corresponding to each detector is connected to the detector power and signal line adapter terminal, and the other end is connected to the branch line and then connected to the branch line and the main line in sequence through the plug-in terminals.

[0023] Specifically, plug-in terminals are soldered to the PCB to form a one-input, three-output adapter plate, which is then fixed to the upper surface of the enclosure. Lead wires are routed through wire troughs to each branch node, where plug-in terminals are used for connection. Because plug-in terminals are used between each node and each section of wiring is numbered, the wiring configuration can be changed as needed and quickly restored to the basic wiring diagram.

[0024] In one embodiment, an opening and closing door panel is provided on the back of the box body via a hinge, so as to remove part of the main line for water immersion test.

[0025] In one embodiment, the detector panel is provided with a transverse wire groove and a longitudinal wire groove.

[0026] Specifically, the detector panel is divided into sixty-four corresponding grids according to its position. Each grid is loaded with a single detector matching long line and the corresponding branch long line. The long line corresponding to the single detector and the branch long line are wound into circles separately and placed on the inside and outside of the panel respectively.

[0027] In one embodiment, a noise interference circuit is also included. The long line of the noise interference circuit surrounds the branch lines of each detector in an S shape and is stabilized. The two ends of the noise interference circuit are respectively connected to a three-phase four-wire socket and a plug. The three-phase four-wire socket is fixed on the side of the shell structure.

[0028] Working Principle: The scheme adopts irregular wiring method, which can impose electromagnetic interference in the bus loop and strong electrical noise interference on the bus loop, so as to restore and simulate the on-site working environment and interference as much as possible, and provide bus communication performance data support, problem analysis methods and problem-solving ideas for product research and development, debugging and technology upgrades.

[0029] The wiring details are as follows:

[0030] Starting from the controller communication board, there are 4 copper core wires: power supply (24V, GND), signal line (S1, S2), each using 2.5mm 2 , 1.0mm 2 Wire diameter, total length of single strand wire is 4040m.

[0031] The total length of the main line is 965m: it is divided into 5 sections and 5 nodes. Starting from the communication board, the lengths of the 5 sections are 400m, 300m, 100m, 100m, and 65m respectively. Of the 400m long first section, 150m can be soaked in water when needed.

[0032] The detectors are irregularly distributed, with branches further branching out from the main line nodes. Each branch is then connected to the detector via a certain length of wire, which fits the actual usage environment.

[0033] The noise interference circuit adopts a three-phase four-wire system, with a single-strand wire diameter of 6mm 2 The noise interference loop surrounds some branch loops. When the power supply of high-power equipment is introduced, the noise interference generated is applied to the communication loop in a radiation manner. At the same time, conventional electromagnetic interference can also be applied on the main line and branch line.

[0034] The beneficial effects of the utility model are as follows:

[0035] 1. The utility model has a reasonable design, optimizes the structure of the long-line vehicle and the detector tooling vehicle, and adopts an integral type; the detector panel is detachable, and each detector can be maintained separately.
