Civil air defense door posture detection device and detection method

Abstract

A civil air defense door posture detection device and a detection method. The device comprises an posture detection unit and a control unit which are integrated; the posture detection unit comprises aposture sensor, and the control unit comprises a processor, a memory, a signal input interface and a switching value signal interface; the posture sensor collects a real-time posture parameter electrical signal and transmits to the processor through the signal input interface, the memory stores original posture parameters, preset alarm parameters, real-time posture parameters, and corner-suspending state information parameters of a civil air defense door compared and judged by the processor, and transmits to the switching value signal interface for amplification, and all the parameters are converted into a switching value signal to control an external station or train signal system to send a corresponding control signal. The detection unit and the control unit of the device form an organic whole, the structure is simple, the impact on the appearance integrality of the civil air defense door is small, installation position restraints are avoided, the installation and replacement are convenient, the service life is long, real-time posture monitoring on the civil air defense door is realized, no monitoring dead zone exists, and the monitoring accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of air defense doors, and in particular relates to an automatic detection device and method for the state of air defense doors. Background technique [0002] After installation, the air defense door in the rail transit area of ​​rail transit is under its own gravity or other external forces, such as man-made damage or the continuous action of the tunnel piston wind, which will cause the performance of the door leaf connector to decrease, resulting in the change of the door leaf posture, such as the door leaf falling (hanging angle), the door leaf Left and right (horizontal) deviation, serious door leaf deviation may cause the door leaf to invade into the driving area (railway area), which brings great potential safety hazard to train running safety. [0003] At present, it is common to install horizontal displacement sensors and vertical displacement sensors for attitude detection of civil air defense doors....

Problems solved by technology

[0002] After the installation of the civil air defense door in the middle rail area of ​​rail transit, under its own gravity or other external forces, such as man-made damage or continuous action of tunnel piston wind, the performance of the door leaf connector will decrease, resulting in a change in the door leaf posture, such as the door leaf falling (hanging angle), the door leaf Left and right (horizontal) deviation, serious deviation of the door leaf may cause the door leaf to invade the driving area (track area), which brings great safety hazards to the safety of train driving

[0003] At present, it is common to install horizontal displacement sensors and vertical displacement sensors for attitude detection of civil air defense doors. This method has the following main shortcomings: First, the displacement sensor needs to have high external conditions, that is, it needs a certain area and is relatively flat and If the complete reference datum plane falls outside the reference datum plane, it is easy to form a monitoring blind spot, and the displacement sensor loses its accuracy or function; second, the displacement sensor is mainly realized by optical means, and its life span is generally only 1-5 years, while the civil air defense door The design life of the door often reaches several decades, and it needs to be replaced very frequently in theory, and the time cost and expense cost of the later replacement are relatively high; the third is to prevent false alarms of the air defense door hanging angle (displacement deviation) in the prior art and often adopt at least two The displacement sensors (two horizontal displacement sensors, two vertical displacement sensors) are mutually verified in pairs (two horizontal displacement sensors are mutually verified, and two vertical displacement sensors are mutually verified) to improve the accuracy rate and increase the application cost virtually. ; Fourth, the use of the displacement sensor must be aligned with two surfaces, one is the tunnel wall, and the other is the ground, that is, the vertical displacement sensor must be aligned with the ground, and the horizontal displacement sensor must be aligned with the tunnel wall, resulting in a relatively fixed installation position of the displacement sensor. The requirements are relatively high; and there are corresponding requirements for the flatness of the wall surface and the ground, which increases the difficulty of construction
