Description

Technical Field

[0001] The present invention belongs to the technical field of suspended single-track switches, and particularly relates to a control system, method, and storage medium for a power push rod of a suspended single-track switch. Background Art

[0002] As a new type of rail transit system, the suspended monorail has the characteristics of strong climbing ability, small turning radius, good passenger experience, and strong cross-regional ability compared with other rail transit systems. In the suspended monorail transit system, the key equipment, the switch, is usually driven by a power push rod to move each device to complete the switch operation. The reliability of the power push rod plays a crucial role in the normal operation of the system.

[0003] In the related art, a travel switch is set on the linear driving stroke of the power push rod. The movement position of the push rod is detected by the travel switch, and the start and stop of the power push rod are controlled according to the movement position of the push rod. However, since the travel switch is a mechanical contact switch, the failure rate is relatively high. Once a failure occurs, the suspended single-track switch cannot work properly, affecting the normal operation of the line. Summary of the Invention

[0039] In an embodiment of the present invention, a suspension single-rail switch power push rod control system includes a power push rod, a controller, a first displacement detection device, a second displacement detection device, and a data conversion and transmission device. Among them, the first displacement detection device and the second displacement detection device are both arranged on the power push rod.

When the second displacement detection device is in a normal state, it automatically switches to the second displacement detection device to control the power push rod to work, thereby reducing the probability of failure of the suspension single-rail switch and improving the safety of the switch, ensuring the normal operation of the line. Description of the Drawings

[0040] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the following will briefly introduce the drawings required for description in the embodiments. Obviously, the following drawings are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0042] Figure 2 It is a schematic flow chart of a suspension single-rail switch power push rod control method provided by an embodiment of the present invention;

[0043] Figure 3 It is a schematic flow chart of another suspension single-rail switch power push rod control method provided by an embodiment of the present invention.

[0044] Reference Signs:

[0045] 1: Power push rod; 2: Controller; 3: First displacement detection device; 4: Second displacement detection device; 5: Data conversion and transmitter. Specific embodiments

[0046] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0047] Figure 1 It is the main structural view of a suspension single-track turnout power push rod control system provided by an embodiment of the present invention. Refer to Figure 1 This suspension single-track turnout power push rod control system includes a power push rod, a controller, a first displacement detection device, a second displacement detection device, and a data conversion and transmitter. Among them, the first displacement detection device and the second displacement detection device are both arranged on the power push rod. The first displacement detection device and the second displacement detection device are respectively used to detect the push rod movement position of the power push rod and control the movement of the power push rod. The first displacement detection device, the second displacement detection device are electrically connected to the data conversion and transmitter. The data conversion and transmitter is used to receive the detection signals sent by the first displacement detection device and the second displacement detection device, convert the detection signals according to preset conditions and send them to the controller. The controller is electrically connected to the first displacement detection device, the second displacement detection device, and the data conversion and transmitter respectively.

[0048] First of all, it should be noted that the suspension single-track turnout power push rod control system provided by the embodiments of this application is applied to an internally movable rail turnout type suspension single-track turnout. More specifically, it is applied to the power push rod, which is the driving mechanism of various lifting, turnout, flipping, locking and other devices in the suspension single-track turnout. Since the internally movable rail turnout type suspension single-track turnout needs to simultaneously perform actions such as lifting and turning the movable rail, flipping and locking the compensating rail when the train passes, and the above devices all use a multi-link mechanism to realize the transmission and operation of the actions. Therefore, a power push rod is arranged in each device, and through the push of one or more power push rods, the smooth turnout of the suspension single-track turnout is realized, and the comfort of vehicle passing is improved. By arranging backup displacement detection devices on the power push rod of the suspension single-track turnout in the embodiments of this application, the push rod movement position of the power push rod can be effectively detected and the movement of the power push rod can be controlled by the control method sent by the controller, thereby improving the running stability of the movable push rod.

[0049] Secondly, it should be noted that the controller in the suspension single-track switch power push rod control system provided by the embodiments of the present application may include a processor, a memory for storing control instructions, and a signal receiving and transmitting device. The controller can be connected to the data conversion transmitter and the power push rod by wire, or can be connected by wireless communication methods such as Bluetooth, WIFI, 3G, 4G, 5G, etc., as long as it is ensured that the time for the controller to receive signal data, process signal data, and then send signal data is short enough and does not affect the switching operation of the suspension single-track switch. The embodiments of the present invention do not make specific limitations on this. When the controller controls the push rod, it receives the detection signal sent by the first displacement detection device or the second displacement detection device through the data conversion transmitter, determines the current movement position of the power push rod, and then sends a movement instruction to the power push rod according to the device control conditions preset in the memory. After receiving the movement instruction, the power push rod executes the movement instruction to control the movement of the power push rod.

[0050] Thirdly, it should be noted that in the suspension single-track switch power push rod control system provided by the embodiments of the present application, the types of the first displacement detection device and the second displacement detection device may be the same or different. For example, both the first displacement detection device and the second displacement detection device can be analog displacement sensors or travel switches, or the first displacement detection device is a rotary displacement detection sensor and the second displacement detection device is a travel switch. The purpose of setting two sets of displacement detection devices is to reduce the risk of out-of-control during the operation of the power push rod through two sets of redundant control systems and improve the overall operation stability of the suspension single-track switch.

[0051] In a possible implementation manner, the first displacement detection device is a rotary displacement detection sensor or an analog displacement sensor. And when the first displacement detection device is a rotary displacement detection sensor, the second displacement detection device is an analog displacement sensor or a travel switch; when the first displacement detection device is an analog displacement sensor, the second displacement detection device is a rotary displacement detection sensor or a travel switch. That is, by setting different types of the first displacement detection device and the second displacement detection device, a small-probability event of simultaneous failure of the two sets of displacement detection devices in the same operating environment can be prevented.

[0052] Finally, it should be noted that both the rotary displacement detection sensor and the analog displacement sensor are types of displacement detection sensors. In the case of technological breakthroughs, new types of displacement detection sensors may appear. Therefore, in the embodiments of the present invention, the types of displacement detection sensors for the first displacement detection device and the second displacement detection device are not specifically limited, as long as they can be set on the power push rod and perform high-precision displacement detection on the movement of the power push rod.

[0053] In an embodiment of the present invention, a suspension single-track switch power push rod control system includes a power push rod, a controller, a first displacement detection device, a second displacement detection device, and a data conversion and transmission device. Among them, the first displacement detection device and the second displacement detection device are both arranged on the power push rod. The first displacement detection device and the second displacement detection device are respectively used to detect the push rod movement position of the power push rod. The first displacement detection device, the second displacement detection device are electrically connected to the data conversion and transmission device. The data conversion and transmission device is used to receive the detection signals sent by the first displacement detection device and the second displacement detection device, and convert and send the detection signals to the controller according to preset conditions. The controller includes a processor and a memory for storing instructions executable by the processor. The controller is electrically connected to the power push rod and the data conversion and transmission device. Since the first displacement detection device and the second displacement detection device that are redundant to each other are arranged on the suspension single-track switch power push rod in the embodiment of the present invention, when the first displacement detection device is in a normal state, the power push rod is controlled by the first displacement detection device. When the second displacement detection device is in a normal state, it is automatically switched to the second displacement detection device to control the power push rod to work, thereby reducing the probability of failure of the suspension single-track switch and improving the safety of the switch, ensuring the normal operation of the line.

[0054] Figure 2 It is a schematic flowchart of a control method for a suspension single-track switch power push rod provided by an embodiment of the present invention. Refer to Figure 2 In the control system of the suspension single-track switch power push rod, the method includes:

[0055] Step 201: Obtain a first detection signal and a second detection signal. The first detection signal is the detection signal of the first displacement detection device sent by the data conversion and transmission device, and the second detection signal is the detection signal of the second displacement detection device sent by the data conversion and transmission device. The first detection signal and the second detection signal at least include detection signal type information, operating state information, and push rod position information.

[0056] Step 202: Determine the control mode of the suspension single-track switch power push rod according to the first detection signal and the second detection signal.

[0057] Step 203: Control the movement of the power push rod according to the control mode of the suspension single-track switch power push rod.

[0058] The embodiments of the present application are applied to a suspension single-rail switch power push rod control system. Through this suspension single-rail switch power push rod control system, when controlling the suspension single-rail switch power push rod, the detection signals of the first displacement detection device and the second displacement detection device sent by the data conversion transmitter can be obtained. According to the detection signal type information, operating status information, and push rod position information included in at least the first detection signal and the second detection signal, the control mode of the suspension single-rail switch power push rod is determined, and the movement of the power push rod is controlled according to the control mode of the suspension single-rail switch power push rod. Since the embodiments of the present invention determine the control mode of the suspension single-rail switch power push rod according to the detection signals of the first displacement detection device and the second displacement detection device, when the first displacement detection device is in a normal state, the first displacement detection device controls the power push rod to work. When the second displacement detection device is in a normal state, it is automatically switched to the second displacement detection device to control the power push rod to work, thereby reducing the probability of faults occurring in the suspension single-rail switch, improving the safety of the switch, and ensuring the normal operation of the line.

[0059] Optionally, before obtaining the first detection signal and the second detection signal, it further includes:

[0061] When the push rod position information included in the detection signal sent by the first displacement detection device is consistent with the push rod position information included in the detection signal sent by the second displacement detection device, according to the detection signal type of the detection signal sent by the first displacement detection device and the detection signal type of the detection signal sent by the second displacement detection device, through the first preset rule, the first detection signal and the second detection signal are determined, and the first detection signal and the second detection signal are sent to the controller;

[0062] When the push rod position information included in the detection signal sent by the first displacement detection device is inconsistent with the push rod position information included in the detection signal sent by the second displacement detection device, stop sending the detection signal to the controller and output an alarm message.

[0063] Optionally, the first preset rule specifically includes:

[0064] When the detection signal type of the detection signal sent by the first displacement detection device is an analog signal, convert the detection signal sent by the first displacement detection device into a bus communication signal, and determine the converted detection signal sent by the first displacement detection device as the first detection signal;

[0065] When the detection signal type of the detection signal sent by the first displacement detection device is a bus communication signal, determine the detection signal sent by the first displacement detection device as the first detection signal;

[0066] When the detection signal type of the detection signal sent by the second displacement detection device is an analog signal, convert the detection signal sent by the second displacement detection device into a bus communication signal, and determine the detection signal sent by the second displacement detection device after conversion as the second detection signal;

[0067] When the detection signal type of the detection signal sent by the second displacement detection device is a bus communication signal, then determine the detection signal sent by the second displacement detection device as the second detection signal.

[0068] Optionally, determine the control mode of the suspended single-rail turnout power push rod according to the first detection signal and the second detection signal, including:

[0069] Determine the operation status information of the first detection signal and the operation status information of the second detection signal;

[0070] According to the operation status information of the first detection signal and the operation status information of the second detection signal, determine the control mode of the suspended single-rail turnout power push rod according to the second preset rule.

[0071] Optionally, the second preset rule specifically includes:

[0072] If the operation status information of both the first detection signal and the second detection signal is normal, then determine that controlling the power push rod according to the detection signal of the first displacement detection device is the first control mode;

[0073] If the operation status information of the first detection signal is normal and the operation status information of the second detection signal is abnormal, then determine to control the power push rod according to the detection signal of the first displacement detection device, and output an alarm signal for the second detection device being abnormal as the second control mode;

[0074] If the operation status information of the first detection signal is abnormal and the operation status information of the second detection signal is normal, then determine to control the power push rod according to the detection signal of the second displacement detection device, and output an alarm signal for the first displacement detection device being abnormal as the third control mode;

[0075] If the operation status information of both the first detection signal and the second detection signal is abnormal, then determine to disconnect the control of the first displacement detection device and the second detection device, and output an alarm signal for both the first displacement detection device and the second detection device being abnormal as the fourth control mode.

[0076] Optionally, control the movement of the power push rod according to the control mode of the suspended single-rail turnout power push rod, including:

[0077] When the control mode of the suspension single-rail switch power push rod is the first control mode, the first displacement detection device is turned on, the second displacement detection device is turned off, and the movement of the power push rod is controlled according to the detection signal of the first displacement detection device;

[0078] When the control mode of the suspension single-rail switch power push rod is the second control mode, the first displacement detection device is turned on, the second displacement detection device is shielded, and the movement of the power push rod is controlled according to the detection signal of the first displacement detection device;

[0079] When the control mode of the suspension single-rail switch power push rod is the third control mode, the first displacement detection device is shielded, the second displacement detection device is turned on, and the movement of the power push rod is controlled according to the detection signal of the second displacement detection device;

[0080] When the control mode of the suspension single-rail switch power push rod is the fourth control mode, the first displacement detection device and the second displacement detection device are shielded, and the movement of the power push rod is stopped.

[0081] All the above optional technical solutions can be combined arbitrarily to form optional embodiments of the present application, and the embodiments of the present application will not be elaborated herein one by one.

[0082] Figure 3 It is a schematic flowchart of another control method for the suspension single-rail switch power push rod provided by the embodiment of the present invention. Refer to Figure 3 . This is applied to the suspension single-rail switch power push rod control system. The method includes:

[0083] Step 301: The data conversion transmitter obtains the detection signal sent by the first displacement detection device and the detection signal sent by the second displacement detection device.

[0084] Among them, the data conversion transmitter is a device for converting and transmitting the data received from the first displacement detection device and the second displacement detection device. Since the bus communication mode can simplify the electrical circuit and improve the anti-interference ability of data transmission, in actual applications, the bus transmission method is mostly used for transmission. When the controller of the first displacement detection device or the second displacement detection device is a detection device without the bus communication mode, such as an analog displacement detection sensor, the signal it sends is an analog signal, which is not compatible with the bus communication mode. Therefore, it is necessary to convert the detection signal and uniformly convert it into the bus communication mode.

[0085] Step 302: When the push rod position information included in the detection signal sent by the first displacement detection device is consistent with the push rod position information included in the detection signal sent by the second displacement detection device, determine the first detection signal and the second detection signal according to the types of the detection signals sent by the first displacement detection device and the second displacement detection device through a first preset rule, and send the first detection signal and the second detection signal to the controller.

[0086] That is to say, when the data conversion transmitter receives the detection signals sent by the first displacement detection device and the second displacement detection device, it is necessary to first determine whether the push rod position information included in the detection signal sent by the first displacement detection device is consistent with the push rod position information included in the detection signal sent by the second displacement detection device. When the push rod position information included in the detection signal sent by the first displacement detection device is consistent with the push rod position information included in the detection signal sent by the second displacement detection device, then determine the type of the detection signal, and determine whether to convert the detection signal according to the type of the detection signal. When the push rod position information included in the detection signal sent by the first displacement detection device is inconsistent with the push rod position information included in the detection signal sent by the second displacement detection device, stop sending the detection signal to the controller and output an alarm message.

[0087] It should be noted that the push rod position information included in the monitoring signals sent by the first displacement detection device and the second displacement detection device represents the position of the current power push rod. For example, when the length of the push rod is 50 cm, when the push rod is in the retracted state, the push rod position information shows 0 cm; when the push rod moves to 25 cm, the push rod position information shows 25 cm; when the push rod is fully extended, the push rod position information shows 50 cm. The above data are only exemplary data, and the embodiments of the present invention do not make specific limitations thereto. When the push rod position information included in the detection signal sent by the first displacement detection device is consistent with the push rod position information included in the detection signal sent by the second displacement detection device, it indicates that the detection data of the two match. At this time, then determine the type of the detection signal, and determine whether to convert the detection signal according to the type of the detection signal. If they are inconsistent, stop sending the detection signal to the controller and output an alarm message.

[0088] When determining the type of the detection signal and determining whether to convert the detection signal according to the type of the detection signal, the conversion transmitter will detect the types of the detection signals and convert the signals in the non-bus communication mode into the bus communication mode in real time according to the first preset rule.

[0089] Among them, the first preset rule can be obtained from user input or from other devices. The first preset rule determines the conversion logic of the data conversion transmitter for the detection signal. Specifically, the first preset rule includes:

[0090] When the detection signal type of the detection signal sent by the first displacement detection device is an analog signal, convert the detection signal sent by the first displacement detection device into a bus communication signal, and determine the converted detection signal sent by the first displacement detection device as the first detection signal;

[0091] When the detection signal type of the detection signal sent by the first displacement detection device is a bus communication signal, determine the detection signal sent by the first displacement detection device as the first detection signal;

[0092] When the detection signal type of the detection signal sent by the second displacement detection device is an analog signal, convert the detection signal sent by the second displacement detection device into a bus communication signal, and determine the converted detection signal sent by the second displacement detection device as the second detection signal;

[0093] When the detection signal type of the detection signal sent by the second displacement detection device is a bus communication signal, then determine the detection signal sent by the second displacement detection device as the second detection signal.

[0094] That is to say, according to the first preset rule, when the data conversion transmitter performs data conversion, if the detection signal types of the first displacement detection device and the second displacement detection device are already bus communication signals, directly determine their detection signals as the first detection signal and the second detection signal. If the detection signal types of the first displacement detection device and the second displacement detection device are not bus communication signals, then convert the detection signal and determine the converted detection signal as the first detection signal or the second detection signal.

[0095] Step 303: Obtain the first detection signal and the second detection signal. The first detection signal is the detection signal of the first displacement detection device sent by the data conversion transmitter, and the second detection signal is the detection signal of the second displacement detection device sent by the data conversion transmitter. The first detection signal and the second detection signal at least include detection signal type information, operating status information, and push rod position information.

[0096] Among them, the detection signal type information refers to the information of the original detection signal type sent by the displacement detection device and the displacement detection device type. The detection signal type information is sent by the displacement detection device and is fixed information.

[0097] Among them, the operation status information refers to the information indicating the current operation status of the displacement detection device. The operation status information of the displacement detection device includes normal or abnormal. When the displacement detection device works normally, the operation status information is normal; when the displacement detection device does not work properly, the operation status information is abnormal.

[0098] Step 304: Determine the operation status information of the first detection signal and the operation status information of the second detection signal.

[0099] It should be noted that when determining the operation status information of the first detection signal and the operation status information of the second detection signal, the operation status information in the first detection signal and the operation status information in the second detection signal can be directly accessed, and the access results can be used as the determination results. For example, if the operation status information accessed in the first detection signal is normal and the operation status information accessed in the second detection signal is normal, it is determined that the operation status information of the first detection signal and the operation status information of the second detection signal are both normal.

[0100] Step 305: Determine the control mode of the suspension single-track switch power push rod according to the operation status information of the first detection signal and the operation status information of the second detection signal according to the second preset rule.

[0101] It should be noted that after determining the operation status information of the first detection signal and the operation status information of the second detection signal, the control mode of the suspension single-track switch power push rod can be determined according to the operation status information of the two. During the determination process, the determination method such as the second preset rule can be executed, or other multi-condition or composite rules can be executed. The embodiments of the present invention do not make specific limitations on this.

[0102] Specifically, the second preset rule includes:

[0103] If the operation status information of both the first detection signal and the second detection signal is normal, it is determined that the power push rod is controlled according to the detection signal of the first displacement detection device as the first control mode;

[0104] If the operation status information of the first detection signal is normal and the operation status information of the second detection signal is abnormal, it is determined that the power push rod is controlled according to the detection signal of the first displacement detection device, and an alarm signal indicating that the second detection device is abnormal is output as the second control mode;

[0105] If the operation status information of the first detection signal is abnormal and the operation status information of the second detection signal is normal, it is determined that the power push rod is controlled according to the detection signal of the second displacement detection device, and an alarm signal indicating that the first displacement detection device is abnormal is output as the third control mode;

[0106] If the operating status information of both the first detection signal and the second detection signal is abnormal, determine to disconnect the control of the first displacement detection device and the second detection device, and output an alarm signal that both the first displacement detection device and the second detection device are abnormal, which is the fourth control method.

[0107] It should be noted that when the first displacement detection device or the second displacement detection device is abnormal, an alarm signal is generated. The alarm signal carries the number of the abnormal displacement detection device. The controller sends the alarm signal to the terminal, and the terminal reminds the user that the displacement detection device is abnormal, so as to timely repair the displacement detection device.

[0108] Step 306: Control the movement of the power push rod according to the control mode of the suspended single-rail switch power push rod.

[0109] Specifically, when controlling the movement of the power push rod according to the control mode of the suspended single-rail switch power push rod, the following method can be executed:

[0110] When the control mode of the suspended single-rail switch power push rod is the first control mode, turn on the first displacement detection device, turn off the second displacement detection device, and control the movement of the power push rod according to the detection signal of the first displacement detection device;

[0111] When the control mode of the suspended single-rail switch power push rod is the second control mode, turn on the first displacement detection device, shield the second displacement detection device, and control the movement of the power push rod according to the detection signal of the first displacement detection device;

[0112] When the control mode of the suspended single-rail switch power push rod is the third control mode, shield the first displacement detection device, turn on the second displacement detection device, and control the movement of the power push rod according to the detection signal of the second displacement detection device;

[0113] When the control mode of the suspended single-rail switch power push rod is the fourth control mode, shield the first displacement detection device and the second displacement detection device, and stop the movement of the power push rod.

[0114] The embodiments of the present application are applied to a suspension single-rail switch power push rod control system. Through this suspension single-rail switch power push rod control system, when controlling the suspension single-rail switch power push rod, the detection signals of the first displacement detection device and the second displacement detection device sent by the data conversion and transmission device can be obtained. According to the detection signal type information, operating state information, and push rod position information included in at least the first detection signal and the second detection signal, the control mode of the suspension single-rail switch power push rod is determined, and the movement of the power push rod is controlled according to the control mode of the suspension single-rail switch power push rod. Since the embodiments of the present invention determine the control mode of the suspension single-rail switch power push rod according to the detection signals of the first displacement detection device and the second displacement detection device, when the first displacement detection device is in a normal state, the first displacement detection device controls the power push rod to work. When the second displacement detection device is in a normal state, it automatically switches to the second displacement detection device to control the power push rod to work, thereby reducing the probability of faults occurring in the suspension single-rail switch, improving the safety of the switch, and ensuring the normal operation of the line.
