The invention discloses an intelligent urine volume accurate metering device for critically ill patients, relates to the technical field of urine volume monitoring, and solves the problem that the urine volume of existing patients is monitored by visual inspection of urine bag scales by nurses, and a fixed time is required for pouring and measuring. Large errors and other issues. An intelligent precise urine volume measurement device for critically ill patients, including a catheter connection tube, a temporary urine placement mechanism is installed on the outside of the bottom end of the catheter connection tube, and a urine volume weighing device is installed on the upper end of the temporary urine placement mechanism. system, the urine volume weighing system includes a connection mounting plate, a locking knob, a connection seat, a weighing body, a display screen, a connection rod, a guide rod and a limit plate, and two Connecting seat. By temporarily storing and monitoring the urine, the present invention is convenient for improving the monitoring accuracy of urine volume, reducing the error of manual measurement, convenient for storing the urine, reducing the number of times of urine dumping, and reducing the workload of medical staff.

The invention discloses a real-time detection and control system and method for displacement and deformation of a foundation pit support body. A data collector collects the inclined angle data, measured by each probe, of each measuring point in a corresponding measuring oblique pipe in the foundation pit support body, and the inclined angle data of each measuring point is sent to a central data processor, the central data processor calculates the displacement data corresponding to each measuring point according to the inclined angle data, coming from the data collector, of each measuring point, thus obtaining the deformation curve of each measuring oblique pipe and the corresponding compensation data of each support point; a D / I conversion instrument converts the compensation data into a current loop signal so as to control the support of a PLC (programmable logic controller) or other industrial controllers for the foundation pit support body and perform ream-time compensation, the aim that the foundation pit support (such as steel support) is subjected to continuous real-time automatic axial force compensation all day long for 24 hours is realized according to the deformation condition, collected in real time, of the measuring oblique pipe, the measuring precision and efficiency are improved compared with those of manual measurement, and the construction quality, efficiency and safety of a foundation pit are improved.

The invention provides automatic laser scanning galvanometer correcting equipment and laser galvanometer equipment. The correcting equipment comprises a control box, a scanning head, stepping motor control modules, photoelectric sensors, two guide rails, conveying belts and sensitive paper, wherein the two guide rails are arranged in parallel. The control box is connected with the scanning head, the stepping motor control modules and the photoelectric sensors. Each stepping motor control module is arranged on the corresponding guide rail and used for driving the corresponding conveying belt to move. Under control of the control box, the scanning head can be driven by the stepping motor control modules and the conveying belts to move along the guide rails in the axial direction. The sensitive paper is arranged between the two parallel guide rails. Each photoelectric sensor is arranged at the starting end of the corresponding guide rail. According to the automatic laser scanning galvanometer correcting equipment and the laser galvanometer equipment, a corrected figure is obtained in a linear-scanning manner; the obtained corrected figure is distortionless, rich in feature points, precise in correction and small in error; the mode that the guide rails are combined with the scanning head is adopted, so that an obtained image is large in view field; and the large-format laser galvanometer machining equipment can be corrected, and the structure of original laser machining equipment does not need to be changed.

The invention discloses an automobile part detecting device which comprises a device body, a water tank device and a control center. A control panel is arranged in front of a display panel and is connected with the display panel electrically. A first sliding block is arranged on the top inside a hardness detecting device and is connected with the hardness detecting device movably. An infrared measuring device is arranged at the left of the upper surface of the device body and is in close contact with the device body. A gravity sensing device is arranged at the right end of a lifting bench andis fixedly connected with the lifting bench. Because of the gravity sensing device, when an automobile part passes by the gravity sensing device, the weight of the automobile part triggers the gravitysensing device and thus the hardness detecting device starts to work; and an automatic control transmission device conveys the automobile part to the inside of the device body for detection by a conveying board. Therefore, automobile part detection is carried out in order and missing detection or empty detection is avoided.
