Research On The ZZJZ Portable Hotbox Alarm & Axis Position Detection Device

With the increasing amount of passenger rail, and constantly improve transport efficiency, as well as accelerating the speed of trains running on road safety put forward higher requirements. "KZS/M-type focus Hotbox alarm" (hereinafter referred to as the "Axis newspaper") promotion, effective solution to the train running bearing temperature monitoring issues, traffic safety has become an important safeguard. Therefore, the performance of centralized alarm, sensor installation status is correct or not, it is directly related to the accuracy of data collection Hotbox.Currently, the manufacturer of factory inspection, testing instrument performance segment side, and will not be sufficient to solve the current car centralized fault alarms that may occur during the installation process, especially for the repair of vehicles segment, yet there is no better test methods and means to ensure that the installation and maintenance of the reliability of the process, there is no use of reliable records.In the preliminary investigation KZS/M-type focus Hotbox alarm management, use the status quo, based on the research and development of "ZZJZ newspaper axial axis portable detection device" (hereinafter referred to as "ZZJZ device"), can be effectively and quickly detected concentration Hotbox alarm failure detection quality of digital temperature sensor detects the correctness of the shaft position sensor is installed, record test data, thus further improving road safety, while reducing the workload of workers.This paper developed ZZJZ portable axle shaft position detection device reported full advantage of current advanced mechatronics technology, the entire detection device into the host, the extension of two parts, where the host is the core of the detection device, including LCD modules, power modules clock module, interface modules, keyboards, communications module for connecting shaft newspaper DB-15 connector (female) for connecting the system of DB-15 connector (pin), IC card interface (wild card) and memory modules (card) and the like. Host main board provides rapid detection axis reported, supporting testing and axial sensor test data records and query and dump functions; extension under the car to provide a single digital sensor (DS18B20) temperature measurement function; host communication can be realized axial extension detection.Currently widespread installation centralized vehicle axle temperature alann, has become an important guarantee traffic safety, to report to work the shaft, the correct installation of the sensor have put forward higher requirements, and lack of effective domestic are simple detection devices. Successful development ZZJZ portable detection device, greatly enhance maintenance efficiency and shorten the working time, to avoid the traditional manual inspection inefficient, error prone and other circumstances. Before, KZS/ M-type railway coaches focus Hotbox alarm can not directly locate the fault location, use of the device can help workers to directly determine the location of the fault, really can effectively eliminate hidden dangers, and reduce operating costs, shorten detection time, the detection process traceability, I believe can be widely promoted.
