Modularized automatic test assembly system of rely protection device and test method of modularized automatic test assembly system

InactiveCN102608464ASimple and convenient on-site test automationSimple and convenient operabilityElectrical testingInterface layerSystem structure
The invention discloses a modularized automatic test assembly system of a rely protection device and a test method of the modularized automatic test assembly system. The modularized automatic test assembly system comprises three layers of system structures: an interface layer, a logic layer and a data layer; the data layer comprises a database and the database is internally provided with a test template and a report template of the rely protection device; the test template is arranged for respectively representing all functions of different rely protection devices of different factories; the report template comprises a test report; a writing position of a test result of the test report is in a user defined mode; through the test template, the system further obtains the evaluation of the performance of the rely protection device; after a test is finished, a test report of the user defined mode can be automatically and immediately generated; and the system finishes an integrated function of testing and evaluating the rely protection device. The modularized automatic test assembly system of the rely protection device and the test method of the modularized automatic test assembly system, disclosed by the invention, have the beneficial effects that the function is complete, and the site problems that the site time testing time is long, a test environment is complicated, the artificial judgment can be wrong and the test report can not be written in time are solved.

A multi-function car digital instrument system

The invention relates to a multifunction automobile digital instrument system which comprises a liquid crystal screen and an embedded singlechip fixed on the back of the liquid crystal screen; sensor data is still read through a bus interface of the prior analogue instrument board, without changing the installation structure of the prior vehicle instrument board. The system is provided with all functions of the prior analogue instruments of an automobile, besides, the system is also provided with functions such as monitoring vehicle running state and fault diagnosis, monitoring driving state of drivers, monitoring vehicle discharge state, vehicle traveling recorder, video reversing radar, GPS navigation, GPRS wireless data transmission and so on. The multifunction automobile digital instrument system of the invention can greatly expand functions of the prior instrument board and make the prior instrument board to be the information processing center of modern automobiles. The application of the system contributes to improving the service life of vehicles, reducing accidental faults, improving the safety of running and driving of vehicles, reducing the cost of use and management of vehicles and realizing informatization of traffic guidance.

Space wedge type irreversible transmission device and whole active driving lifting mechanism

The invention discloses a space wedge type irreversible transmission device, which is a space wedge type friction overrun clutch by taking a poking part as an input member, and has total functions of a bidirectional overrun clutch with a poking pawl in the prior art. The transmission device comprises a rotating guide mechanism consisting of an annular guide piece and an intermediate piece with guide teeth, and a friction piece for receiving annular bag members of the two members, and an axial force enclosed space wedge mechanism is formed by the annular guide piece, the intermediate piece and the friction piece. The poking piece is connected to the intermediate piece and the guide piece in a non-rotational manner; and subsequent contact of the two members in a circumferential direction is realized by means of a connected circumferential gap so as to drive the two members to make de-wedge rotation, however, the two members are not driven by active rotation of the guide piece. By the irreversible transmission device, a whole active driving lifting mechanism for hoisting equipment can be obtained, ascending and descending motion of the mechanism needs to be driven by power, wedge non-return brake and power driving alternatively occur in a complementary mode, and any response or conversion time is not needed.
