The TCU, i.e., Transmission Control Unit, i.e., automatic Transmission Control Unit, is commonly used in automatic transmissions such as AMT, AT, DCT, CVT, and the like. Automatic speed change control is realized, and driving is simpler.
Along with social development, the application of intelligent technologies in various fields is a necessary social product in a great trend. Along with the increasing popularization of the intelligent control technology concept, the intelligent control technology system is applied to production and manufacturing so as to solve the problem of increasing labor cost, improve the production efficiency, reduce the quality loss caused by quality factors such as artificial uncontrollable and the like, increase the reliability of product quality and the like. There is also a trend towards the intellectualization of TCU testing and also of burn-in testing of TCUs.
The current aging test system comprises the following components:
the non-intelligent aging test management system comprises: each aging test board in the aging cabinet is an independent aging test system, and after being loaded into the test board, a specially-assigned person is required to confirm the aging test state of the aging test system in real time. When a plurality of (dozens or even hundreds) products are aged simultaneously, corresponding human resources need to be increased, and the increase of the number of aged products managed by personnel inevitably leads to product quality risks and causes quality hidden troubles.
The existing intelligent aging test management: at present, intelligent systems are also available, which control the on-off of a plurality of node interface circuits through a special controller system to connect products to be monitored, and when the state of a certain product needs to be monitored, the controller sends an instruction to connect the corresponding node interface circuits. When the aging amount of the products is increased, the monitoring products are circularly connected with the corresponding node interface circuits through the controller, so that the monitoring is not real-time. Moreover, each product needs to occupy one node, so that the requirement on the controller is high, the number of interface circuits (mostly adopting relays) of the node is correspondingly increased, and the later maintenance cost is correspondingly increased; the TCU product aging experimental process is an inspection process for simulating whether a product can work normally or not in a specified environment temperature, and is also an important inspection means for verifying the quality reliability of the product.
The existing aging test system has the following defects:
1. the requirements on the skill and responsibility of the inspector are high. When the number of aging tests is increased, the increase of human resources is inevitably caused, and staff are easy to fatigue, so that hidden danger of product quality is caused;
2. the products in the aging cabinet are aged simultaneously, each aging process is independent, and the real-time aging state of the products needs to be confirmed by inspectors in sequence and cannot be considered end to end. Therefore, when the product is bad, the product with the fault cannot be disposed in time;
3. for the existing intelligent aging test system, when the aging quantity of products is increased, the requirement on the quantity of nodes accessed by a controller is increased, interface circuits on the nodes are also required to be correspondingly increased, and the later maintenance cost is higher.
