[0002] In fields such as industrial control, building automation, and environmental control, thorough testing is required before deploying control systems to the actual site to ensure their reliability, stability, and safety.

[0003] Currently, traditional integrated equipment generally involves stationary equipment and mobile testing, or mobile equipment combined with fixed testing fixtures. Some testing vehicles on the market only move the mobile equipment or separate the equipment and testing fixtures, resulting in a large footprint and low flexibility.

[0004] Therefore, in view of this, we will study and improve the existing structure to provide an integrated functional testing tooling cart, in order to achieve a more practical value. Utility Model Content

Technical problems to be solved In view of the problems existing in the prior art, the purpose of this utility model is to provide an integrated functional testing fixture trolley, which can greatly shorten the test preparation and turnaround time, improve the test efficiency, save valuable floor space in the workshop or laboratory, and greatly improve the flexibility of the entire device in use. 2. Technical Solution

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An integrated functional testing fixture trolley includes an aluminum profile trolley frame. Mounting plates are fixedly installed on the back and two sides of the aluminum profile trolley frame. A table is fixedly installed in the middle of the aluminum profile trolley frame. Mounting plates on the aluminum profile trolley frame above the table are assembled to form a high-level integrated equipment housing. Mounting plates on the aluminum profile trolley frame below the table are assembled to form a low-level integrated equipment cabinet. Multiple functional testing devices are fixedly installed inside both the high-level and low-level integrated equipment housings by bolts. The high-level and low-level integrated equipment housings are arranged parallel to each other vertically. Two directional wheels and two omnidirectional wheels are fixedly installed inside the aluminum profile trolley frame. The two directional wheels are arranged parallel to each other and distributed at the rear bottom of the aluminum profile trolley frame, while the two omnidirectional wheels are arranged parallel to each other and distributed at the front bottom of the aluminum profile trolley frame.

[0008] Furthermore, the aluminum profile trolley frame is made of 2mm thick 4040 aluminum profile, and the aluminum profile trolley frame is assembled using frame corner brackets.

[0009] Furthermore, the mounting plate is made of stainless steel 201, and the stainless steel plate is fixed to the mounting plate using nuts without pre-embedded nuts.

[0010] Furthermore, the tabletop is made of 18mm antistatic board and is installed using flat corner brackets and self-tapping screws.

[0011] Furthermore, inside the high-position integrated equipment box or the low-position integrated equipment cabinet, the bottom of each functional testing device is padded with a hard silicone plate.

[0012] Furthermore, the mounting plates of the high-position integrated equipment box and the low-position integrated equipment cabinet are each provided with a number of evenly distributed screw positioning holes. The mounting plate, tabletop, and hard silicone plate are all fixedly equipped with wire grooves.

[0013] Furthermore, the high-level integrated equipment cabinet has a front hinged flip-top structure, and there is a height difference between the flip-top of the high-level integrated equipment cabinet and the table. The low-level integrated equipment cabinet has a front-opening cabinet structure.

[0014] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: This solution integrates the testing fixtures with a mobile cart, enabling "the testing lab to move with the personnel." Testers can easily push the entire testing system to any equipment or workstation that needs to be tested, saving the time spent moving the equipment under test or the time spent by testers traveling between different fixed workstations. This greatly shortens the test preparation and turnaround time and improves testing efficiency. Then, through the upper and lower double-layer box design, a variety of testing equipment is compactly integrated into a vertical space.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0018] Please see Figure 1 - Figure 3 An integrated functional testing fixture trolley includes an aluminum profile trolley frame 1. Mounting plates 2 are fixedly installed on the back and two sides of the aluminum profile trolley frame 1. A table 3 is fixedly installed in the middle of the aluminum profile trolley frame 1. The mounting plates 2 on the aluminum profile trolley frame 1 and above the table 3 are combined to form a high-level integrated equipment box 101. The mounting plates 2 on the aluminum profile trolley frame 1 and below the table 3 are combined to form a low-level integrated equipment cabinet 102. Various functional testing equipment are fixedly installed inside the high-level integrated equipment box 101 and the low-level integrated equipment cabinet 102 by bolts. The high-level integrated equipment box 101 and the low-level integrated equipment cabinet 102 are arranged parallel to each other vertically. Two directional wheels 4 and two omnidirectional wheels 5 are fixedly installed inside the aluminum profile trolley frame 1. The two directional wheels 4 are arranged parallel to each other and distributed at the bottom rear end of the aluminum profile trolley frame 1. The two omnidirectional wheels 5 are arranged parallel to each other and distributed at the bottom front end of the aluminum profile trolley frame 1.

[0019] By installing the equipment in two separate upper and lower enclosures, functional zoning is achieved. Heavy or basic equipment such as power supplies and main control units can be placed in the lower integrated equipment enclosure 102, while instruments and interfaces that are frequently operated and observed can be placed in the upper integrated equipment enclosure 101, which is in line with ergonomics.

[0020] Tabletop 3 provides a convenient testing platform. The combination of directional wheels 4 and omnidirectional wheels 5 ensures flexible movement and stable straight-line propulsion of the trolley. The overall structure enables the mobility of the testing fixture, facilitating rapid deployment on the production floor or between different workstations.

[0021] See Figure 1 Specifically, the aluminum profile trolley frame 1 is made of 2mm 4040 aluminum profile, and the aluminum profile trolley frame 1 is installed using frame corner brackets to build the overall frame.

[0022] This ensures simple and flexible installation of the aluminum profile trolley frame 1 and even the entire tooling trolley.

[0023] Secondly, the use of specific-specification industrial aluminum profiles and frame corner bracket connections gives the aluminum profile trolley frame 1 the advantages of robust structure, light weight, and corrosion resistance. Simultaneously, this construction method offers extremely high flexibility and scalability; the frame can be easily modified, expanded, or adjusted without special tools to adapt to future changes in testing equipment or functional additions, thus improving the trolley's lifespan and versatility.

[0024] See Figure 1 Specifically, mounting plate 2 is made of stainless steel 201, and mounting plate 2 is installed by using nuts without pre-embedded nuts when fixing the stainless steel plate.

[0025] Stainless steel 201 offers excellent strength, rigidity, and corrosion resistance, effectively supporting various testing equipment. The use of pre-embedded nuts for installation means that mounting points can be flexibly adjusted as needed, rather than being fixed in the initial design, greatly enhancing the flexibility of equipment layout and facilitating later maintenance and equipment replacement.

[0026] See Figure 1 Specifically, the tabletop 3 is made of 18mm antistatic board, and the tabletop 3 is installed using flat corner brackets and self-tapping screws.

[0027] The anti-static board effectively prevents ESD damage to electrostatic sensitive components during testing, improving the reliability and safety of the test. The use of flat corner brackets and self-tapping screws for installation makes the installation and removal of the tabletop 3 very simple and secure, facilitating maintenance of the equipment inside the enclosure beneath the tabletop 3.

[0028] Specifically, inside the high-level integrated equipment enclosure 101 or the low-level integrated equipment cabinet 102, the bottom of each functional testing device is padded with a hard silicone plate.

[0029] Hard silicone sheets offer excellent shock absorption, cushioning, and insulation properties. They effectively absorb vibrations generated during equipment operation and impacts from carriage movement, protecting precision testing equipment from damage. Simultaneously, their insulating properties enhance electrical safety between devices.

[0030] See Figure 2 , Figure 3 Specifically, the mounting plates 2 of the high-position integrated equipment box 101 and the low-position integrated equipment cabinet 102 are provided with a number of evenly distributed screw positioning holes 201. Using the appropriate screws in conjunction with the screw positioning holes 201, the equipment can be easily fixed.

[0031] Cable channels are fixedly installed on mounting plate 2, tabletop 3, and hard silicone plate.

[0032] The wiring uses cable trays, which require pre-drilled holes in the stainless steel plate. The contactor is mounted using a guide rail. The stainless steel plate can be secured to the cable trays and guide rails using pop rivets, making it easy to install securely.

[0033] For aluminum profiles with concentrated wiring surfaces, double-layer plates can be used. The wiring is routed on the back of the stainless steel plate close to the equipment, and then covered with a stainless steel plate of the same size. This not only ensures electrical safety but also maintains the aesthetics of the trolley.

[0034] Specifically, the high-level integrated equipment cabinet 101 has a front hinged flip-top structure, and there is a height difference between the flip-top of the high-level integrated equipment cabinet 101 and the table 3. By increasing the height difference between the outer casing door and the lower casing, it is easier to test the opening and closing of the equipment door.

[0035] The low-level integrated equipment cabinet 102 has a cabinet structure with an open front.

[0036] It facilitates the storage and access of large or heavy equipment (such as high-power power supplies, industrial control computers, etc.), and makes it convenient to pick up, put down and wire the equipment.

[0037] Working principle: The aluminum profile trolley frame 1 is divided into a high-level integrated equipment cabinet 10 and a low-level integrated equipment cabinet 102 by a table panel 3. Based on testing requirements and ergonomic principles, different functional testing equipment (such as power supplies, industrial computers, signal generators, and measuring instruments) are bolted into these two cabinets respectively. Typically, heavier or less frequently operated equipment (such as main control computers and high-power power supplies) is placed in the lower cabinet, while equipment requiring frequent operation, observation, or wiring is placed in the upper cabinet, achieving functional zoning and preventing interference between them.

[0038] When testing is required at different workstations or in different workshops on the production site, operators can directly push the trolley. The layout of two directional wheels 4 at the front and two omnidirectional wheels 5 at the rear ensures stable direction and flexible turning during pushing. After the trolley moves to the target workstation, its position can be fixed by the brakes on the omnidirectional wheels to prevent slippage.

[0039] Testing Operation: Upon arrival at the workstation, operators can prepare for testing on the anti-static table 3, such as placing the device under test and connecting test cables. The high-level integrated equipment cabinet 10 adopts a front-hinged flip-top structure, allowing convenient operation of the test equipment inside the cabinet by opening the flip-top. The low-level integrated equipment cabinet 102 has a front-opening cabinet structure, facilitating the storage and retrieval of equipment and cable connections.

[0040] All connecting cables between devices are neatly laid out using cable trays provided on mounting plate 2, tabletop 3, and hard silicone plate to prevent cables from becoming tangled or twisted, and to avoid detachment or damage due to pulling. The hard silicone plate at the bottom of the equipment serves to absorb shock, cushion, and insulate, protecting the equipment during trolley movement and operation. The anti-static tabletop effectively prevents static electricity from damaging sensitive components.

[0041] The evenly distributed array of screw positioning holes 201 on the mounting plate 2 allows the installation position of the test equipment to be flexibly adjusted as needed. The aluminum profile trolley frame 1 and the modular design make the structure of the entire trolley easy to expand or modify to adapt to future updates of the test equipment or the addition of test functions.

[0042] Example 2 Based on the above embodiment 1, further description is provided.

[0043] Specifically, based on an integrated functional testing fixture cart, an integrated electromechanical equipment simulation testing system is provided. This system can reproduce complex industrial scenarios containing various types and quantities of actuators and environmental sensors through equivalent simulation without relying on real field equipment, achieving comprehensive, efficient, and safe testing and verification of control systems.

[0044] It includes: a central control unit, a multi-channel actuator simulation module, and an environmental parameter detection module; the central control unit is communicatively connected to the multi-channel actuator simulation module and the environmental parameter detection module, respectively; The multi-channel actuator simulation module includes: ① Wind turbine status simulation unit: It consists of a 40-channel relay array. The activation and deactivation status of each relay is used to simulate the "running" and "stopping" status of a wind turbine on site, thereby simulating the rotation conditions of 40 wind turbines.

[0045] ② Single-phase water pump simulation unit: It consists of 8 single-phase motors and is used to simulate the water supply and start-up / stop operations of 8 single-phase powered water pumps on site.

[0046] ③ Three-phase motor simulation unit: It consists of two three-phase water pumps / motors and is used to simulate the operation of two large three-phase power supply water pumps or motors on site. It can test the three-phase power control logic of the control system.

[0047] ④ DC driver simulation unit: It consists of two 48V DC motors and their drive circuits, and is used to simulate the motion state of dual-channel 48V DC drivers in the field.

[0048] The environmental parameter detection module integrates a temperature sensor, a humidity sensor, a carbon dioxide concentration sensor, and a negative pressure sensor, which are used to detect the corresponding physical parameters in the test environment in real time and simulate the actual environmental conditions on site.

[0049] In actual testing: ① This system integrates the detection of four different types of actuators (digital switch fans, single-phase AC equipment, three-phase AC equipment, and DC drive equipment) and four key environmental parameters into one unit. It simulates the fan using relays, resulting in extremely low cost and high reliability. By precisely matching different types of field pumps and drives with motors of different power and power supply types, a "one-stop" high-fidelity simulation of complex field conditions is achieved.

[0050] ② Testers can freely program and control any combination and timing logic of 40 relays, 8 single-phase motors, 2 three-phase motors and 2 48V DC motors through the central control unit to simulate various normal, abnormal and extreme working scenarios without operating real large and high-risk equipment. The testing process is safe and controllable.

[0051] This breaks the dependence of testing on the physical site, greatly improving the flexibility and efficiency of testing.

[0052] ③ The system deeply integrates actuator simulation with environmental parameter detection. For example, test cases can be written such that when 10 fans and 2 water pumps are started in a simulated manner, the system should detect temperature drops, negative pressure changes, etc. This achieves closed-loop verification of the control system logic, the test results are closer to reality, and potential control logic defects and environmental linkage problems are effectively discovered.

[0053] ④ It eliminates the huge cost and space required to build a real test bench, significantly shortening the cycle from development to verification of the control system, making it particularly suitable for scenarios such as R&D, factory inspection, and teaching and training.

[0054] Example 3 Further description is provided based on the above embodiments 1 and 2.

[0055] ① Equivalence of Digital Quantities to State Quantities (Wind Turbine Simulation): A "40-channel relay array" is used to simulate the "manual / stop / automatic" states of 40 wind turbines. The key is not the number of relays, but the establishment of a low-cost, high-reliability direct mapping relationship between the digital output points (DO) of the control system and the physical operating states of the wind turbines. The clicking sound, indicator light illumination, and current switching of a relay represent the start or stop of a large wind turbine. This provides an extremely cost-effective solution for testing the group control logic of a large number of switching devices in a control system.

[0056] ② Equivalent from Small Power to Large Power (Water Pump Simulation): This method uses "8 small-power single-phase motors" and "2 small-power three-phase water pumps" to simulate "8 single-phase water pumps" and "2 three-phase high-power motors" in the field, respectively. The core idea is to completely replicate the behavior of large water pumps / motors in terms of electrical control characteristics (such as start / stop current, phase sequence requirements, and contactor control logic) using small, safe, and low-cost motors. The test system does not need to concern itself with the head and flow rate of the simulated water pumps; it only needs to ensure that "they start and stop correctly according to instructions, and that the feedback signals (such as current and status) received by the control system are correct." This solves the safety, cost, and space challenges in testing high-power equipment.

[0057] ③ Dynamic simulation of DC drivers: Two 48V DC motors and their drive circuits are used to simulate a dual-path driver in the field. The key is to simulate the dynamic changes of the driver's start and stop, so as to test the correctness of the control system's control logic for complex motion control such as speed regulation and forward and reverse rotation.

[0058] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
