Integrated equipment quality appraisal

integrated equipment takes modular integration and intelligent control as its core principles. By integrating sensing, processing, execution and other functional units, it realizes multi-system collaborative operation and is widely used in smart cities, industrial automation, new energy and other fields. In smart cities, it integrates traffic signal control, environmental monitoring and emergency response functions; in industrial scenarios, it integrates production control, quality inspection and equipment operation and maintenance modules; in the new energy field, it serves as an integrated solution for energy storage, inverter and grid connection. Compared with traditional discrete equipment, integrated equipment has the characteristics of efficient collaboration, energy saving and consumption reduction, and convenient operation and maintenance. It is a key equipment for Industry 4.0 and new infrastructure construction.

Zhongke Testing is a product quality appraisal service organization registered with the court. It can provide integrated equipment quality appraisal services. It has a professional appraisal team and advanced instruments and equipment to provide fair and accurate appraisal results for integrated equipment quality appraisal.

As the complexity of integrated equipment increases, quality dispute cases gradually increase. The judicial dispute focuses on:

1. Performance index dispute: whether the system response time meets the standard and whether the data collection accuracy meets the design value;

2. Integration defects: incompatible communication protocols between modules and insufficient electromagnetic compatibility leading to malfunctions;

3. Software algorithm loopholes: control logic errors and fault diagnosis model misjudgment rates exceeding 5%;

4. Environmental adaptability issues: abnormal function after high and low temperature cycles, and substandard vibration resistance.

Integrated equipment quality appraisal technical methods include:

1. Appearance inspection: Check the appearance of the equipment for scratches, deformation, rust and other defects.

2. Functional test: Functional test of the device, including starting, running, stopping, alarming, etc.

3. Component testing: dismantle the equipment and test key components, including accuracy measurement, material composition analysis, etc.

4. Data analysis: Collect equipment operation data and analyze whether its performance indicators meet the requirements.

A smart factory of the applicant signed an "Intelligent Manufacturing Integrated Equipment Procurement Contract" with a technology company of the respondent, agreeing to purchase 3 sets of equipment integrating robotic arms, visual inspection and MES systems. After being put into production, the equipment frequently experienced mechanical arm malfunctions and abnormal detection data, resulting in product scrap rates exceeding 10%. The factory believed that the equipment had a design defect and demanded compensation for losses. The technology company argued that the problem was caused by improper operation, and both parties took it to court.

Identification analysis results:

The quality analysis expert group discussed and comprehensively analyzed the relevant information of the "integrated equipment", contract technical agreement, on-site investigation case materials and other data, and made the following quality analysis opinions:

The robotic arm of the integrated equipment involved in the case is incompatible with the communication protocol version of the visual inspection module (TCP/IP 1.1 misuse) 1.0), the data packet loss rate reaches 8%; the electromagnetic compatibility is insufficient, and the harmonics of the frequency converter cause the detection camera image to be blurred. The motion control algorithm does not consider the dynamic response delay of the robotic arm, and the path planning error exceeds 2mm; the visual detection threshold setting is unreasonable, and the misjudgment rate of good products reaches 5%.

Technology Company failed to conduct protocol compatibility testing and electromagnetic compatibility design in accordance with the contract, and the error in algorithm parameter setting was the main reason for equipment problems.

Integrated equipment quality appraisal report should include the following content:

1. Appraisal purpose and basis.

2. Model, specification, manufacturer and other information of the equipment being identified.

3. Identification method.

4. Identification results (including whether there are quality problems, causes of problems, etc.).
