The invention discloses an earth pressure balance shield machine hob wear monitoring device and method based on image analysis. The hob cutter box assembly is opposite. The invention has the advantages of simple structure, convenient installation, clear field of vision, good protection effect and washing effect, and provides a stable and reliable structural basis for image analysis and processing. The on-line measurement of tool wear can be realized through the wear monitoring method, and at the same time through monitoring Video directly observes the hob status, which improves the safety, convenience, economy and reliability of hob wear monitoring.

The invention discloses a switch for communication engineering, which comprises a switch body. The switch body is provided with a plurality of card slots on the top edge of the side wall near the communication cable socket. The top of the switch body is provided with a horizontal groove, and the grooves communicate with multiple The card slot, the limit rod is fixedly clamped in the groove, and a plurality of limit blocks are fixedly connected on the side wall of the limit rod, wherein each limit block is clamped in the corresponding card slot, and the limit rod Both ends are fixedly connected with tough plastic belts, and the switch body is fixedly connected with a horizontal column on a symmetrical side wall away from the communication cable socket, and one end of the column is fixedly connected with a clamping ball. The present invention can realize the clamping of the communication cables, and can efficiently and quickly clamp multiple communication cables, so as to ensure the installation and maintenance of the communication cables, and also reduce the possibility of poor contact between the cables and the switch body during the pulling process. In this case, the normal use of the switch body is guaranteed.

The invention provides a method and system for predicting a central zone temperature of a cross temperature measurement device of a blast furnace throat. The method comprises the steps that a course variable of a blast furnace throat temperature related to the central zone temperature of the cross temperature measurement device of the blast furnace throat is collected; the collected course variable is pre-processed, and noise peak jumping data and high-frequency noise data are removed; and a central zone temperature prediction model is used to predict the central zone temperature of the cross temperature measurement device of the blast furnace throat. The system comprises a collection module, a pre-processing module and a prediction module. According to the invention, input and output historical data selected by the prediction model of the central zone temperature is used to predict future central zone temperature output of the cross temperature measurement device; relations between the temperature output and control input can be expressed accurately; when a central temperature sensor of the cross temperature measurement device needs to be repaired or is damaged, a basis can be provided for a blast furnace operator to make accurate judgments and adjust systems of upper and lower parts of a blast furnace in time; and further, steady, efficiency and safe running of the blast furnace can be implemented.

The invention relates to the field of the Internet of Things monitoring devices, in particular to an Internet of Things monitoring system of a pipeline valve. The Internet of Things monitoring systemof the pipeline valve comprises a valve, an outer connecting pipe, a fixing structure, a sealing structure, a rotating structure, an alarming structure and a camera, wherein through arrangement of therotating structure, the pressure of water can be utilized to drive the rotating structure to rotate when the connecting part of the outer connecting pipe and the valve is broken and water leakage occurs, so that 360-degree rotation of the camera can be realized, then omnibearing monitoring can be carried out conveniently, namely when the water flows out of a water outlet pipe, the plurality of impellers distributed on a rotating shaft in an annular array mode can rotate under the action of the water pressure, so that the rotating shaft can be driven to rotate, a first gear fixed outside the rotating shaft synchronously drives a second gear to rotate, the outer diameter of the first gear is smaller than the outer diameter of the second gear, the mechanical principle that the small gear isused for driving the big gear wheel, so that the water pressure can be ensured to drive the impellers to rotate.

The invention discloses a multiloop combination-switch lever-type mechanical interlocking mechanism which comprises an isolation switch spindle, an isolation switch, an interlocking slide block, a first lever rotary type mechanism, a connecting rod, a second lever rotary type mechanism, an interlocking block, a first main-chamber large cover, a second main-chamber large cover, a third main-chamber large cover, an opening mechanism. The isolation switch spindle is fixed on the isolation switch and passes through the interlocking slide block. The interlocking slide block is slidingly connected with the connecting rod. The second lever rotary type mechanism is slidingly connected with the interlocking block. The first lever rotary type mechanism is slidingly connected with the connecting rod. The first main-chamber large cover, the second main-chamber large cover and the third main-chamber large cover are arranged in series. The first main-chamber large cover and the third main-chamber large cover are fixed with the interlocking block. The opening mechanism is connected with the first main-chamber large cover, the second main-chamber large cover and the third main-chamber large cover. In the multiloop combination-switch lever-type mechanical interlocking mechanism of the invention, a lever work principle is adopted. And the mechanism is suitable for being installed and used in multiloop combination-switch equipment.
