[0044] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment.

The term "more than two" includes two or more than two situations.

[0046] Converter is a rotatable cylindrical steelmaking blast furnace. The converter can rotate around the tilting axis to achieve the tilting of the converter. For example, Figure 1 As shown, Figure 1 11 is the converter body, and 12 is the tilting axis of the converter.

[0047] In the process of converter operation, in order to realize real-time control of the converter, it is necessary to accurately obtain the real-time tilt angle value of the converter. When a tilt encoder is installed on the tilt shaft of the converter, the tilt encoder can obtain the real-time tilt angle value of the converter. In actual use, the tilt encoder is also fixed to the tilt shaft through a coupling, and the real-time tilt angle of the converter is determined by observing the rotation angle value of the tilt shaft.

[0048] The inclination encoder is fixed to the tilting shaft by mechanical fixing. During the continuous rotation of the tilting shaft, the mechanical parts may become loose due to factors such as aging and falling off. When the inclination encoder has a position deviation, there will be a large difference between the real-time tilting angle value measured and the actual tilting angle of the converter. If the converter is controlled based on the real-time tilting angle value at this time, the operation error is large and it is easy to cause an accident. For example, the actual tilt angle has reached the pouring angle value, but the real-time tilting angle value has not reached the pouring angle value, which may easily cause the material in the converter to not be poured at the specified time or position.

[0049] In order to solve the technical problem of inaccurate measurement results of the inclination angle of the converter, the present application provides the following embodiments to solve the above problem:

[0050] This embodiment provides a device for detecting the inclination angle of a converter. Figure 2 , which is a structural diagram of the device of this embodiment, including: an inclination encoder 21, an inclinometer 22 and a controller 23.

[0051] The inclination encoder 21 is used to be arranged at the active end of the converter tilting to obtain the first inclination angle of the converter.

[0052] In the inclination angle detection device (hereinafter referred to as the detection device) provided in this embodiment, since the converter mainly relies on the tilting axis for tilting, the position of the converter close to the tilting axis is used as the active end of the converter, and the position of the converter away from the tilting axis is used as the passive end of the converter.

[0053] In the detection device, an inclination encoder is installed at the active end of the converter, and the inclination encoder obtains the real-time tilting angle value of the converter during operation as the first inclination angle.

[0054] The inclinometer 22 is used to be arranged at the passive end of the converter tilting to obtain the second inclination angle of the converter.

[0055] On the basis of the converter being equipped with an inclination encoder, the detection device in this embodiment is further provided with an inclinometer. It is an instrument for measuring the inclination angle of an object. It is usually composed of a sensor, a signal processing circuit, a display device and other parts. The high-performance three-dimensional motion attitude measurement system based on MEMS technology includes a three-axis gyroscope and a three-axis accelerometer, which provide high-precision, high-dynamic, and real-time compensated three-axis attitude angles. When the converter tilts, the accelerometer installed inside the inclinometer on the converter will sense the change in the gravity component. By calculating and processing these data, the inclinometer can accurately measure the inclination of the converter. Specifically, the inclinometer measures the acceleration of gravity and the acceleration of the converter relative to the vertical direction, and uses the tiny mass block inside the accelerometer to sense the change in the direction of gravity, thereby calculating the inclination angle of the converter as the second inclination angle.

[0056] The controller 23 is connected to the inclination encoder 21 and the inclinometer 22, and is used to obtain the first inclination angle and the second inclination angle, and determine the actual inclination angle of the converter according to the first inclination angle and the second inclination angle.

[0057] During the tilting of the converter, the inclination encoder and the inclinometer respectively obtain the corresponding first inclination angle and second inclination angle for the converter. The controller is connected to the inclination encoder and the inclinometer respectively, directly obtains the first inclination angle and the second inclination angle from the inclination encoder and the inclinometer, and can further calculate the actual inclination angle of the converter based on the first inclination angle and the second inclination angle. The controller can be a programmable logic controller (PLC).

[0058] In the technical solution of this embodiment, in the process of measuring the inclination angle of the converter, an inclination encoder and an inclinometer arranged at different positions of the converter are used to respectively obtain a first inclination angle and a second inclination angle used to represent the actual inclination angle of the converter. After receiving the first inclination angle and the second inclination angle, the controller processes the first inclination angle and the second inclination angle, and finally obtains the actual inclination angle of the converter. By adopting the technical solution of this application, the actual inclination angle of the converter can be obtained by using the inclination encoder and the inclinometer together, reducing the possibility of abnormal inclination angle data of the converter due to mechanical failure of the inclination encoder or other factors, and maintaining the normal operation of the converter.

[0059] In a possible embodiment, the tilt angle detection device further includes:

[0060] A power module, the power module is connected to the inclinometer and is used to supply power to the inclinometer;

[0061] A transmission module, the transmission module is connected to the inclinometer and the controller respectively, and is used to transmit the second tilt angle to the controller;

[0062] A display device is connected to the controller and is used to display the second tilt angle obtained by the inclinometer.

[0063] In this embodiment, other modules connected to the inclinometer are further included so that the inclinometer can normally perform the function of obtaining the second tilt angle.

[0064] The power module is used to provide power to the inclinometer. In one embodiment, the power module can further provide power to the inclinometer encoder and controller to support the normal operation of the encoder and controller. Exemplarily, when the power module provides power to the inclinometer, the power module can be a DC regulated power supply to provide stable DC 24V power to the inclinometer.

[0065] The transmission module is used to support the transmission of the second tilt angle from the inclinometer to the controller. According to the transmission method, the transmission module may include a wired transmission module and a wireless transmission module. When the transmission module is a wired transmission module, the wired transmission module may adopt a cable transmission method for transmission, and the cable may be stored in a spring cable reel. The spring cable reel is mainly composed of a reel, a spring, a transmission shaft and other parts. Its working principle is to realize the retraction and release of the cable through the energy storage and release of the spring, so that the cable can automatically expand and contract with the movement of the equipment, maintain a certain tension, and avoid problems such as cable entanglement, knotting or excessive stretching.

[0066] The display is connected to the controller. After the controller acquires the second tilt angle, the controller sends the second tilt angle to the display, and displays the second tilt angle through the display. Exemplarily, the second tilt angle can be displayed by displaying a line graph.

[0067] For example, Figure 3 , which is a schematic diagram of the module structure of this embodiment, wherein 31 represents an inclinometer, 32 represents a spring cable reel, 33 represents a DC regulated power supply, 34 represents a PLC, and 35 represents a display.

[0068] In this embodiment, other related devices for supporting the operation of the inclinometer are further disclosed, which are used to support the normal operation of the inclinometer and enable the second inclination angle obtained by the inclinometer to play a greater role.

[0069] Based on the disclosure of an embodiment of a converter inclination angle detection device, the present application further discloses an embodiment of a converter inclination angle detection method. The method embodiment is applied to a controller in the converter inclination angle detection device, such as Figure 4 As shown, specifically including:

[0070] Step 401, obtaining a first tilt angle from a tilt encoder and a second tilt angle from an inclinometer.

[0071] During the activation process of the converter, the inclination encoder and the inclinometer are synchronously activated. In one embodiment, when the converter is not activated, the converter is in a position perpendicular to the ground, and the converter can be considered to be in zero position. When the converter is activated, the converter tilts according to the activation signal, and the angle value of the converter relative to the ground deviates. The controller can activate the inclination encoder and the inclinometer according to the activation signal of the converter. In another embodiment, the inclination encoder and the inclinometer can continuously monitor the converter, and when the converter is no longer in zero position, the inclination encoder and the inclinometer respond to the position change signal of the converter to activate and obtain the inclination angle of the converter.

[0072] After the inclination encoder and the inclinometer are activated, the inclination angle of the converter will be continuously obtained. For example, the inclination angle can be obtained at preset intervals. The preset interval of the inclination encoder and the preset interval of the inclinometer can be the same or different.

[0073] Step 402, determining the actual inclination angle of the converter according to the first inclination angle and the second inclination angle.

[0074] During the tilting of the converter, the inclination encoder and the inclinometer respectively obtain the corresponding first inclination angle and second inclination angle for the converter. The controller is connected to the inclination encoder and the inclinometer respectively, directly obtains the first inclination angle and the second inclination angle from the inclination encoder and the inclinometer, and can further calculate the actual inclination angle of the converter based on the first inclination angle and the second inclination angle.

[0075] In this embodiment, during the tilting process of the converter, the controller can simultaneously obtain the first tilt angle and the second tilt angle, and can further calculate the actual tilt angle of the converter based on the first tilt angle and the second tilt angle, and through multiple tilt angles, the accuracy of the final actual tilt angle is ensured.

[0076] In a possible embodiment, the process of determining the actual inclination angle may be: obtaining an average value of the first inclination angle and the second inclination angle, and taking the average value as the actual inclination angle of the converter.

[0077] After simultaneously acquiring the first inclination angle and the second inclination angle, the actual inclination angle can be jointly determined based on the average value of the first inclination angle and the second inclination angle. In addition to the average value calculation in this scheme, any inclination angle can be selected from the first inclination angle and the second inclination angle as the actual inclination angle of the converter, and the other inclination angle can be used as a reference inclination angle of the selected inclination angle. The reference inclination angle can be used to verify whether the selected inclination angle data is accurate. Exemplarily, the controller receives the first inclination angle and the second inclination angle, and the controller uses the second inclination angle as the actual inclination angle, and uses the first inclination angle as the reference inclination angle of the second inclination angle to verify whether the second inclination angle is reasonable.

[0078] In the process of verifying whether the second actual tilt angle is reasonable, in one embodiment, the controller may first obtain the tilt angle difference between the first tilt angle and the second tilt angle; and then determine whether the tilt angle difference is less than a first threshold;

[0079] If the inclination angle difference is less than the first threshold value, the first inclination angle or the second inclination angle is finally used as the actual inclination angle of the converter.

[0080] In this embodiment, the controller can calculate the difference between the first tilt angle and the second tilt angle as the tilt angle difference, and further determine whether the tilt angle difference is greater than the first threshold value. If the tilt angle difference is greater than the first threshold value, it can be considered that the difference between the first tilt angle and the second tilt angle is too large, and it can be considered that there may be an inclination data abnormality between the first tilt angle and the second tilt angle. Since the inclination encoder and the inclinometer use different working principles, the probability of both failing at the same time is small. Therefore, the accuracy of using the inclination encoder and the inclinometer to verify the abnormality with each other is high.

[0081] In one embodiment, if the tilt angle difference is greater than or equal to a first threshold, an alarm signal indicating an abnormality of the tilt encoder and / or the inclinometer is output.

[0082] When the difference in inclination angle is large, there is an abnormality in an inclination angle data between the first inclination angle and the second inclination angle. Therefore, when it is determined that the first inclination angle or the second inclination angle is abnormal, an alarm signal indicating the inclination encoder and / or the inclinometer is output. For example, when the second inclination angle is used as the actual inclination angle and the first inclination angle is used as the reference inclination angle, when the difference in inclination angle is large, it can be considered that the inclinometer is abnormal and an alarm signal is output; it can also be considered that both the inclinometer and the inclinometer encoder are abnormal and an alarm signal is output.

[0083] In one embodiment, when it is determined that at least one of the inclinometer or the inclination encoder is abnormal, this embodiment can further implement the determination of the abnormal sensor. The specific steps include:

[0084] Adjust the converter to a preset position, wherein the preset position corresponds to a reference inclination angle, and the reference inclination angle is a known angle value; obtain a first test inclination angle of the inclination encoder and a second test inclination angle of the inclinometer when the converter is in the preset position; obtain a first angle difference between the first test inclination angle and the reference inclination angle, and if the first angle difference is greater than a second threshold, determine that the inclination encoder is abnormal; obtain a second angle difference between the second test inclination angle and the reference inclination angle, and if the second angle difference is greater than a third threshold, determine that the inclinometer is abnormal.

[0085] When it is determined that at least one of the inclinometer or the inclination encoder is abnormal, the converter is adjusted to a preset position, which is a reference inclination angle that can be used for sensor testing. When adjusting the converter position, the adjustment process is not affected by the sensor abnormality and can be directly adjusted to the preset position manually or automatically. The preset position can be designed based on the actual working conditions of the converter. By way of example, in addition to the initial position of the converter, the preset position can also include a position where the converter is perpendicular to the ground.

[0086] When the converter reaches this position, since the angle value of this position is known, it is possible to verify whether the two sensors of the inclinometer or the inclination encoder are abnormal based on the known angle value. During the verification process, the first angle difference between the first test inclination angle obtained by the inclinometer and the reference inclination angle, and the second angle difference between the second test inclination angle obtained by the inclination encoder and the reference inclination angle are obtained at this position, and it is determined whether the first angle difference and the second angle difference are too high. If the first angle difference and / or the second angle difference are too high, it can be determined that the inclinometer or the inclination encoder is abnormal.

[0087] In one embodiment, in the process of determining whether the inclinometer or inclination encoder is abnormal, one or more preset positions can be selected, and combined with the comparison results of each preset position, it is determined whether the inclinometer or inclination encoder is abnormal, so as to achieve accurate verification of the inclinometer or inclination encoder.

[0088] In one embodiment, it also includes:

[0089] Obtaining a zero position interval of the converter corresponding to when the first inclination angle of the inclination encoder is zero, wherein the zero position interval includes an upper position limit value and a lower position limit value;

[0090] Obtaining the calibration tilt angle of the converter detected by the inclinometer when it is at the upper position limit and the lower position limit;

[0091] Based on the calibration inclination angle, the zero position interval of the converter corresponding to the first inclination angle of the inclination encoder being zero is calibrated.

[0092] The technical solution of this embodiment also includes the step of using an inclinometer to verify the inclination encoder. When the converter is in the initial position, the converter is 90° to the ground. This position is used as the 0 position of the converter. The converter can rotate forward and reverse at this position. The inclinometer encoder can rotate with the converter. The position of the inclinometer encoder perpendicular to the ground is used as the mechanical 0 position. When the inclinometer encoder starts to rotate, since the mechanical 0 position of the installed mechanical component is relatively wide, it is difficult for the inclinometer encoder to accurately determine the actual 0 position during the calibration process. The technical solution of this embodiment further discloses a related technical solution for calibrating the inclinometer encoder by using an inclinometer. In this solution, the zero position of the inclinometer encoder is used as an interval. The inclinometer is used to determine the inclination angle corresponding to the upper and lower limits of the zero position interval, so that the inclinometer encoder can determine the angle range corresponding to its own mechanical 0 position. Exemplarily, the inclinometer determines that the upper limit value of the zero position interval of the inclination encoder is 1°, and the lower limit value is -1°. The inclination encoder can determine that when the converter is in the range of (-1°, 1°), the inclination angle obtained by itself is 0°, and based on the interval range of (-1°, 1°), it can determine the exact inclination angle corresponding to the inclination encoder when the converter is in other positions.
