Description

Modular electromagnetic shielding combined through test system structure platform

Technical Field

The utility model relates to an automatic testing technique and modern electrical interconnection technical field involve quick expansion and accompany resource organization mode and the implementation scheme of guarantee electromagnetic shield test equipment system architecture and hardware architecture.

Background

In most applications, ATE automatic test equipment or ATS automatic test systems employ standard cabinet structure platforms to carry test resources and the installation of related equipment, and the electrical interconnection between the test resources or test equipment is implemented by means of interconnection cables disposed in the cabinets. The structural platform and the electrical signal interconnection technical scheme of the test system are designed according to the functional requirements of the determination system, and the test system and the equipment are usually subjected to field installation and debugging through a certain installation workflow. The device works in fixed places and work environments without the need for movement and rapid deployment. With modern electronic measurement and detection technologies, particularly in the field of measurement and control, under the promotion of the application of high-performance computer microprocessor technology, the application industries, application occasions and application environments of automatic detection equipment and a guarantee system are rapidly expanded to the fields of meeting diversified, generalized, modularized, motorized, combined and reconfigurable application requirements, such as measurement and control equipment, emission and control equipment, maintenance and guarantee equipment and the like in emergency field measurement and monitoring equipment, rescue communication guarantee equipment, field temporary measurement and control equipment and military electronic equipment, and undertake the task mission of rapid development, motorized use and accompanying guarantee. This presents new challenges for traditional test system architectures and interconnection solutions for electrical signals.

In order to meet the requirements, the current main technical scheme is to divide the test resources installed in the equipment cabinets (25-40U) into several small combined units according to functions, and install the combined units in small-sized portable transport protection boxes, for example, the solution of the amateur that adopts the ecscan transport protection box architecture ATE test system in the first 90 s of the last century. The method is characterized in that a structural platform is built on site by transporting protective boxes, and the protective boxes are connected in a sleeve type matched bolt locking mode; and then the test resources are communicated with the equipment by using external interconnection cables between the protective boxes to realize movable and transportable field test equipment, and the scheme is still a structural platform and equipment interconnection solution adopted by most of the conventional motorized measurement and control systems

In the prior art, only the structure platform for bearing and installing the equipment is changed from a cabinet structure to a structure of combining a plurality of portable cases, and the interconnection cable fixedly arranged in the original cabinet needs to be moved outside the combined unit to complete the direct interconnection between the equipment. Therefore, a large number of criss-cross external cables are interconnected among the combined unit chassis, and the interconnected cables are disassembled and assembled once when the combined unit chassis is moved and transferred each time, so that inconvenience is brought to the disassembly and assembly of the system. Particularly, in the transfer process of the equipment, a special cable packing box is required to be configured for external interconnection cables to carry out cable storage and protection management on cable connectors, and the external interconnection cables cannot be lost or damaged, otherwise, a test system cannot work; when the system is re-deployed, a specially trained technician is required to ensure that the system is familiar with the interconnection relationship and is responsible for interconnection identification and prevention of interface misplug accidents; the structural platform mode brings inconvenience to the use of the test system, and the efficiency of the motorized accompanying test is greatly reduced.

Secondly, because of the requirement of moving and lifting, the dead weight of the box body needs to be limited, the combined box used in the prior art adopts a large amount of light materials, but because of the problem of structural design, if the front and rear frame openings of the box body formed by extruding, bending, enclosing and welding the aluminum profile are adopted, the deformation resistance is poor when the structural design is heavy load, the bearing capacity is weak, the bearing capacity (under the condition that deformation is not generated) of each unit is limited within 80kg, the density of unit bearing equipment is reduced, the number of combined units of the test system can be increased, and the cost of the test system is improved. In addition, the combination stacking of the box body is close to a locking mechanism of a sleeve type matched bolt arranged on the shell, the gap is overlarge, and the combination stress point is on the shell of the box body, so that the combination stacking capacity is reduced, and the deformation resistance and the bearing capacity of the structural platform can not meet the requirement of through combination stacking.

The combination units of the combination system must adopt a certain combination scheme, and the stacking position of the combination units cannot be changed in use. The corresponding interconnection cables only adopt a one-to-one design, all cable lengths and connector types are different, and the interconnection cables among units are not changeable under the constraint of an electrical interconnection scheme, so that the reconfiguration of the function of the test system cannot be supported.
