The invention discloses a monitoring system for crack growth conditions of a pressure vessel containing vertical internal crack defects, which belongs to the technical field of safety analysis of pressure vessels. The monitoring system comprises a sensor unit and an arithmetic unit. The sensor unit is connected with the arithmetic unit and sends monitored information to the arithmetic unit. The arithmetic unit comprises a strain value calculation module, which is connected with the sensor unit, acquires the data of the outer surface of the container detected by the sensor unit and calculates a corresponding strain value according to the data; a depth calculation module, which is connected with the strain value calculation module, acquires the strain value and calculates the depth of an internal crack of the container according to the strain value; a stress intensity factor calculation module, which is connected with the depth calculation module, acquires the value of the crack depth and calculates the value of a stress intensity factor at the tip of the crack according to the value of the crack depth; and a determination module, which is connected with the stress intensity factor calculation module, acquires the value of the stress intensity factor at the tip of the crack and compares the value with a fracture toughness value of a material from which the pressure vessel is made; wherein comparison results output by the determination module characterize the state of the crack and indicate whether the pressure vessel should be on service. According to the invention, the growth state of the crack is obtained through rational detection and calculation; and the safe service situation of the pressure vessel is determined, and high reliability is obtained.

The invention discloses a diagnosis method, a cloud server and a system of a universal energy station equipment, wherein the method includes: obtaining the relevant state parameters of each process equipment according to the type of each process equipment of a plurality of process equipment; judging each process equipment Whether the relevant status parameters of the equipment meet the preset conditions; if the preset conditions are met, the current operating status of each process equipment is obtained according to the relevant status parameters of each process equipment; according to the current operating status of each process equipment and related status parameters Predict the running trend within the preset time, and get the diagnosis result according to the running trend within the preset time. This method can obtain the diagnosis result according to the running trend within the preset time, so that various performance indicators of the equipment can be monitored in real time, and the purpose of online diagnosis of the pan-energy station equipment based on the industrial cloud can be realized, the accuracy of the diagnosis can be improved, and the accuracy of the diagnosis can be improved. The real-time performance can effectively ensure the reliability of monitoring and reduce operating costs.

The invention belongs to the technical field of bare stranded wire take-up, and particularly relates to an anti-scratch branching device. The device comprises a suspension frame, an adhesive tape releasing roller is rotationally matched with an extension rod located on the wire inlet side of a take-up roller, and an adhesive tape taking-up roller is rotationally matched with an extension rod located on the wire outlet side of the take-up roller; and a take-up tangent point is located on the advancing path of an adhesive tape, the advancing height of the adhesive tape located on the wire inletside of the take-up roller is lower than that of a bare stranded wire, and the advancing speed of the adhesive tape is consistent with that of the bare stranded wire. The device further comprises a monitoring sensor used for monitoring the position of the take-up tangent point, the monitoring sensor sends current take-up tangent point position information, and therefore the controller controls a movable block and a sliding block at a suspension frame to generate corresponding actions so as to keep the take-up tangent point on the advancing path of the adhesive tape all the time. According to the invention, the scratch-free function of bare stranded wires, especially aluminum wires, during take-up can be realized simply, conveniently and quickly; and the device is compact in structure, reliable and stable in work, capable of achieving the purpose of automatic production and beneficial to actual production and application.

An elevator all-element health and safety monitoring system, characterized in that: the system includes a phased array visible light and infrared integrated monitoring module (1-1), a sound pickup module (1-2), an intelligent processing module (1-2) 3) and an external control module (1‑4); the present invention realizes the identity recognition of the occupants inside the elevator, the detection of fever characteristics, and the changing characteristics of facial expressions and neck dynamics caused by cough symptoms through a phased array visible light and infrared integrated monitoring module , to realize real-time monitoring of the health status of the occupants in the elevator, so as to effectively control the legacy of the virus in the elevator and the mutual infection between the sick people; through the fusion of the cough symptom facial and neck dynamic change characteristics and sound characteristics acquired by the video, Based on the fusion of multi-feature information, the cough symptom assessment of the occupants in the elevator is realized, and the all-factor health assessment of the personnel is realized in combination with the fever characteristics. The assessment accuracy is high and the monitoring reliability is effectively guaranteed.
