The invention discloses an automatic assembling line of a liquefied petroleum gas cylinder valve and relates to an improvement on production equipment of a liquefied petroleum gas cylinder valve. The automatic assembling line is characterized by consisting of a loading working platform, a valve core assembling working platform, a connecting piece assembling working platform, a valve rod assembling working platform, a rubber pad assembling working platform, an oil coating working platform, a nut assembling working platform, a nut screwing working platform, a paper pad assembling working platform, a hand wheel assembling working platform, a spring assembling working platform, a round nut assembling working platform, a finished product blanking working platform and a line body. The automatic assembling line has the beneficial effects that a workpiece is clamped and conveyed by adopting a mode of automatic loading of a vibrating disc and stepping transmission so as to be transferred in a reciprocating manner of returning to the original position; and after the assembly of all the working platforms is finished in circulation, the blanking of the workpiece in next circulation is carried out, and the movement of the mechanism is more accurate by utilizing a cylinder and a linear guide rail. A sensor is adopted to sense whether the workpiece exists, a signal is transmitted to a PLC (programmable logic computer) and the PLC sends an instruction to execute the actions of all the working platforms and carry out closed-loop control.

The invention relates to an intelligent logic verification system and method of power five-prevention, and belongs to the field of power system operation. The system comprises an input unit, a storageunit, a checking unit and an output unit, the input unit is used to log in a historical operation ticket or input a new operation sequence, and establishes an initial operation ticket model; the storage unit stores the historical operation ticket and a new operation ticket, and uses the stored operation tickets as a simulation test sample; the checking unit comprises forward and backward checkingunits, the forward checking unit carries out forward simulation operation of the operation sequence of the operation ticket, checks whether the anti-error logic of the forward operation of the operation ticket is correct, and if YES, the next unit is entered; the backward checking unit carries out backward disordered simulation operation on the operation sequence of the operation ticket, and checks whether the anti-error logic can pass, and if NO, the next unit is entered; and the output unit generates an operation ticket from the initial operation ticket model that passes checking, and stores the generated operation ticket in the storage unit synchronously.

An industrial robot suitable for use in a mechanical production workshop, comprising a housing (1); the bottom of the housing (1) is provided with driving wheels (2); a first push rod (3) is fixedly connected to the top of the inner wall of the housing (1); a first hinge seat (4) is fixedly connected to the bottom of the first push rod (3); a testing plate (5) is hinged to the bottom of the first hinge seat (4); the bottom of the testing plate (5) is provided with movable columns (6); a second push rod (7) is fixedly connected to the top of the inner wall of the housing (1); a marking brush plate (8) is movably connected to the bottom of the second push rod (7); a speed sensor (9) is provided on the front surface of the second push rod (7); a sliding groove (10) is provided at the top of the housing (1); sliding blocks (11) are slidably connected to the inner wall of the sliding groove (10); and a screw rod (12) is fixedly connected to one side of each of the sliding blocks (11). The present invention solves the problem that the existing steel plate or steel material flatness testing methods mostly perform manual measurement using a measurement tool, have slow testing efficiency and a poor testing effect, and are inconvenient for a user to use.

The invention discloses a method for detecting and analyzing radiated electromagnetic interference of wiring harnesses of a power conversion system of an automobile. In the method, reasonable detecting steps are designed for detecting primary radiated interference wiring harnesses and detecting the distribution frequency band and size of the radiated electromagnetic interference generated by eachof the wiring harnesses, so as to direct engineering technical personnel to eliminate the radiated electromagnetic interference of the wiring harnesses of the power conversion system and to conveniently implement the excellent electromagnetic compatibility design for the wiring harnesses of the power conversion system. The method disclosed by the invention has the advantages that the steps are compact and the implementation is convenient.

The present invention provides a data analysis system and method, using a third-party data platform, intelligent face recognition and sign-in terminal, data access server, data analysis server and other systems, based on room type data, combined with water and electricity consumption, Takeaway situation, access control situation, and house registration situation are the four dimensions, establish the relationship with the target households, and combine historical data with the cross-entropy loss function of logistic regression, iterate weight parameters and intercept parameters, and automatically obtain accurate data analysis As a result, the target households were found in a timely manner. Compared with the traditional "door-to-door visits and public reports", the coverage rate is higher and the accuracy is better, and the households will not be disturbed by false reports.

The invention relates to the technical field of unmanned ships and provides a frogman pre-warning method and system based on an unmanned ship. The frogman pre-warning method based on the unmanned shipcomprises the steps of enabling a first unmanned ship to generate a dispatching instruction according to a coverage area range parameter and detection equipment of the first unmanned ship and a received coverage area range parameter of detection equipment of each unmanned ship; and transmitting a dispatching message carrying the corresponding dispatching instruction to one or more unmanned shipsaround the first unmanned ship. According to the frogman pre-warning system based on the unmanned ship, the motility of each unmanned ship and the detection ability of each unmanned ship in a water area are sufficiently utilized; when one unmanned ship detects a frogman, a first area range detection network can be constructed around the unmanned ship within a short time; the existence of the frogman within the area range can be effectively checked to prevent cooperative diving of multiple frogmen.
