Description

Technical Field

[0001] The present invention relates to the technology of switch machine notch monitoring, in particular to a method for a notch sensor that can be displayed and calibrated inside a switch machine. Background Art

[0002] The notch of a switch machine reflects the close-fitting degree of the switch rail, which is related to the train operation safety. A notch displacement sensor, also known as a notch sensor, is mainly divided into an image-type notch sensor and a magnetoelectric notch sensor, and is a device that collects and outputs a notch value or a notch image. The notch sensor transmits the notch image or displacement data to the monitoring and analysis device inside the switch machine, and then uploads it to the indoor processing and analysis module and the data display and alarm module through a communication module. The indoor data display and alarm module draws real-time data curve graphs and alarms for abnormal data of multiple switch machines. This solution is mostly used in the current notch monitoring system.

[0003] To achieve notch calibration, it is necessary for outdoor maintenance personnel and indoor operators to cooperate, or add a wireless module and a handheld device. During the installation and maintenance of the existing image-type notch sensor, on-site staff need to debug the notch sensor, such as adjusting the installation position and installation angle. After the on-site staff adjust the notch, they notify the indoor staff to use the current picture as the initial position. Sometimes the uploaded picture is not clear or cannot be recognized, and the on-site staff need to readjust the position again. It is often necessary to adjust and confirm back and forth, and the work efficiency is very low. Luo Tong proposed a wireless display unit and a switch machine notch monitoring system. By adding a wireless display module, including a wireless communication module and a handheld intelligent mobile terminal, the notch image collected by the notch sensor is uploaded wirelessly to the handheld intelligent mobile terminal, and the on-site personnel can directly calibrate and confirm it, saving the inconvenience of indoor calibration and outdoor adjustment.

[0004] Most magnetoelectric sensors are of an integral structure and integrally potted. When a fault occurs in the notch sensor on-site, the notch sensor often needs to be replaced as a whole. Since the potting glue is hard after curing and has a good confidentiality effect, the replaced notch sensor cannot be repaired, and it is difficult to locate the cause of the problem, which is not helpful for the establishment of a product fault library. The magnetoelectric notch sensor uses a wireless module to communicate wirelessly with a handheld device, and the staff can view the notch value on-site with the handheld device and set and calibrate the notch sensor.

[0005] The use of handheld devices brings convenience as it allows the notch value to be viewed without opening the switch machine cover. However, there are also some drawbacks. First, it increases the complexity of the system. Maintenance personnel need to carry various tools, including the handheld device required to view and calibrate the notch. As a result, the handheld device is often mechanically damaged when packed with other tools, and in severe cases, it can affect the usage function. Second, according to the railway standard "TB / T 3386 - 2023 Switch Notch Monitoring System Equipment", the notch value of the switch machine should have an outdoor on-site display function, and the handheld device does not belong to the components of the switch notch monitoring system equipment. Third, the display function is not comprehensive. For hydraulic switch machines, if it could also display the oil pressure value during the switching process and the maximum oil pressure value after the switching is completed, maintenance personnel could judge whether the transmission of the switch machine is abnormal based on these pressure values.

[0006] There are also two forms of the in-machine display function of notch information: One is to integrate the display function on the monitoring and analysis device inside the switch machine, sharing the main control unit with the monitoring and analysis device. Therefore, it is relatively convenient to obtain data from various sensing devices inside the machine. Since the monitoring and analysis device itself has powerful functions and many peripheral interfaces, its volume is relatively large, and the orientation of the display interface is restricted by the installation location, resulting in inconvenience for maintenance personnel to view.

[0007] The other is to use an independent display module to implement the display function. For a switch notch monitoring device without an in-machine display function, an external independent display module is added to communicate with the monitoring and analysis device, thereby obtaining various maintenance data for convenient viewing when the staff opens the cover. Compared with the first solution, the layout of the display interface is more flexible and convenient. However, it also brings the drawbacks of increasing system complexity and increasing cables. At the same time, this solution still requires a handheld device to perform notch calibration and parameter settings. Summary of the Invention

[0008] The purpose of the present invention is to provide a method for a notch sensor that is convenient to use and allows maintenance personnel to easily view information, which can be displayed and calibrated inside the switch machine.

[0009] The purpose of the present invention is achieved as follows. It relates to a method for a notch sensor that can be displayed and calibrated inside the switch machine, characterized in that: on the surface of the magnetoelectric notch displacement sensor, there are a display screen, buttons, status indicators, and a detection unit. The display screen, buttons, and status indicators are respectively electrically connected to the detection unit, and the detection unit is electrically connected to the interface of the magnetoelectric notch displacement sensor. The detection unit obtains the data information of the magnetoelectric notch displacement sensor and controls the display screen through receiving commands from the buttons to display the notch value and turnout status information in real time.

[0010] Further, the detection unit calibrates the notch value through the display screen and keys, communicates with the acquisition extension, and queries the temperature and humidity parameters in the switch machine. When the magnetoelectric notch displacement sensor works on a hydraulic switch machine, it further queries the oil pressure and oil level information of the hydraulic switch machine.

[0011] The display screen displays the indication values of parameters such as the notch value and the temperature and humidity value.

[0012] The keys include an up arrow, a down arrow, a Menu menu key, and an enter key. The menu page is operated through the up arrow, down arrow, Menu menu key, and enter key in the keys. The menu page includes functions such as calibrating the notch value, setting the machine number and turnout number, calibrating the total notch value, querying the temperature, humidity, external locking force, oil pressure, and oil level corresponding to the maintenance data of the switch machine. Through the menu page, the turnout maintenance personnel can intuitively understand and master the movement situation and health status of the switch machine.

[0013] The keys are on one side of the display screen. The up arrow and down arrow are used to move the current selection cursor in the menu key. When entering numbers such as calibrating the notch value and setting the machine number, the up arrow and down arrow are used to adjust each digit value, and the enter key is used to confirm.

[0014] The status indicator lights are divided into multiple colors to indicate the status of the current turnout notch and the notch sensor. Green indicates that the turnout has entered the normal position or reverse position state and the sensor can read the notch value. Yellow indicates that the turnout is in the process of conversion. Red indicates that the notch sensor data is incorrect. The indicator light not being on indicates that the notch sensor is not powered on.

[0015] The specific calibration method of the present invention is as follows: The outdoor staff opens the switch machine cover, requests to move the turnout back and forth once, so that the locking column falls into the notch. At this time, the notch value is observed manually, the Menu key on the surface of the notch sensor is operated, and the cursor is moved to "calibrate the notch value" by using the up and down arrows, and the enter key is pressed to enter the calibration of the notch value.

[0016] The up arrow and down arrow are used to adjust the numerical size, and the enter key is used to confirm each digit. When the last digit is confirmed, the display screen will show the prompt message "calibration successful" and automatically switch to the main page, displaying the just-calibrated value, completing the calibration in one direction.

[0017] The beneficial effects of the present invention are as follows: the gap sensor in the present invention integrates the functions of measurement, display and calibration, has a compact size, and is suitable for installation in various types of switch machines; when the gap sensor is installed for the first time, or when recalibration is required due to gap adjustment, the staff can directly use the buttons of the gap sensor to calibrate the gap value. The calibration method has a simple process and high work efficiency, which not only avoids the need for indoor manual positioning of the gap during image gap sensor calibration, and the complex process of indoor and outdoor confirmation and waiting, but also reduces the burden of carrying a handheld device on the road; at the same time, the status indicator light can be used to understand the current status of the turnout gap and the gap sensor, providing useful information for the establishment of a fault library for the gap sensor and turnout maintenance work; the device uploads the measurement data of the gap displacement sensor to the acquisition extension, and can obtain the measurement values ​​of other sensors connected to the acquisition extension by inquiry, and intuitively display them on the display screen of the gap sensor, which is an effective solution to the problem that the current magnetoelectric gap sensor cannot meet the outdoor field monitoring function of the gap value.
