[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention rather than all structures are shown in the drawings.

[0037] Figure 1 Schematic diagram of the structure of the first electronic red flag status monitoring system for railway port freight yards provided by an embodiment of the present invention, as Figure 1 shown, the electronic red flag status monitoring system 100 for railway port freight yards includes: a first signal sending device 10, located on the side of the electronic red flag 200 for railway port freight yards away from the railway line, for sending a first distance signal to the electronic red flag 200 for railway port freight yards; a second signal sending device 20, located on the side of the electronic red flag 200 for railway port freight yards away from the railway line, and arranged with the first signal sending device 10 along a first direction (such as Figure 1 the Y direction shown in the figure), for sending a second distance signal to the electronic red flag 200 for railway port freight yards; the first direction Y is parallel to the extending direction of the electronic red flag 200 for railway port freight yards; a control device 30, electrically connected to the first signal sending device 10 and the second signal device 20 respectively, for obtaining the first distance signal and the second distance signal, and determining the status of the electronic red flag for railway port freight yards according to the first distance signal, the second distance signal, and a preset distance.

[0038] Specifically, the electronic red flag status monitoring system 100 for railway port freight yards is located on the side of the electronic red flag 200 for railway port freight yards away from the railway line, that is to say, the electronic red flag 200 for railway port freight yards is located between the electronic red flag status monitoring system 100 for railway port freight yards and the railway line, so that the electronic red flag status monitoring system 100 for railway port freight yards can monitor the status of the electronic red flag 200 for railway port freight yards.

[0039] Specifically, the state of the electronic red flag 200 at the railway port freight yard can be in an upright state, an inclined state, an evacuation state, etc. The state monitoring system 100 of the electronic red flag at the railway port freight yard monitors whether the electronic red flag 200 at the railway port freight yard is erected in place to ensure the warning effect and control of the electronic red flag at the railway port freight yard on the safety of the railway line. It should be noted that when the electronic red flag 200 at the railway port freight yard is not erected in place, there is a risk that the electronic red flag 200 at the railway port freight yard will intrude into the railway line, which will in turn affect the normal parking of freight trains. Therefore, it is necessary to monitor the state of the electronic red flag 200 at the railway port freight yard in real time.

[0040] Specifically, the electronic red flag 200 at the railway port freight yard includes a back plate 201. Both the first signal sending device 10 and the second signal sending device 20 are located on one side close to the back plate 201. Along the first direction Y, the distance between the first signal sending device 10 and the second signal sending device 20 is known. If there is a point O on the line connecting the first signal sending device 10 and the second signal sending device 20, the distance between the first signal sending device 10 and the point O is L1, the distance between the second signal sending device 20 and the point O is L2, and the first signal sending device 10 sends a first distance signal S1 to the back plate 201, and the second signal sending device 20 sends a second distance signal S2 to the back plate 201. In the first right triangle formed by the first signal sending device 10, the point O, and the back plate 201, according to the Pythagorean theorem, the control device 30 can determine the first current distance D1 between the point O and the back plate 201; in the second right triangle formed by the second signal sending device 20, the point O, and the back plate 201, according to the Pythagorean theorem, the control device 30 can determine the second current distance D2 between the point O and the back plate 201. Furthermore, the control device 30 can calculate the average value of the first current distance D1 and the second current distance D2, thereby obtaining the current distance between the state monitoring system of the electronic red flag at the railway port freight yard and the electronic red flag at the railway port freight yard.

[0041] Specifically, the preset distance can be understood as the distance between the electronic red sign in the railway port freight yard and the electronic red sign status monitoring system of the railway port freight yard when the electronic red sign in the railway port freight yard is erected in place, that is, the distance between point O and the backboard 201 when the electronic red sign in the railway port freight yard is erected in place. If the current distance is equal to the preset distance, it indicates that the current electronic red sign in the railway port freight yard is erected in place. If the current distance is greater than or less than the preset distance, it indicates that the current electronic red sign in the railway port freight yard is in a withdrawn or tilted state, and there is a risk that the electronic red sign in the railway port freight yard invades the railway line. At this time, the electronic red sign status monitoring system of the railway port freight yard can send an alarm signal for the operation and maintenance personnel to adjust the status of the electronic red sign in the railway port freight yard, so as to ensure that the electronic red sign in the railway port freight yard is erected in place, and to ensure the warning effect and control of the electronic red sign in the railway port freight yard on the safety of the railway line.

[0042] It should be noted that the electronic red sign status monitoring system of the railway port freight yard can monitor the status of the electronic red sign in the railway port freight yard in real time.

[0043] In the electronic red sign status monitoring system of the railway port freight yard provided by the embodiment of the present invention, there is a point on the connection line between the first signal sending device and the second signal sending device, and the distance from the first signal sending device to this point is known, and the distance from the second signal sending device to this point is known. Then, according to the distance from the first signal sending device to this point and the first distance signal, the Pythagorean theorem control device can determine the first current distance between this point and the backboard. Then, according to the distance from the second signal sending device to this point and the second distance signal, the Pythagorean theorem control device can determine the second current distance between this point and the backboard. By calculating the average value of the first current distance and the second current distance, the distance between the electronic red sign status monitoring system of the railway port freight yard and the electronic red sign in the railway port freight yard can be obtained, and it can be judged whether the electronic red sign in the railway port freight yard is erected in place according to the current distance and the preset distance, so as to realize the monitoring of the status of the electronic red sign in the railway port freight yard.

[0044] Optionally, Figure 2 FIG. is a schematic structural diagram of the second electronic red sign status monitoring system of the railway port freight yard provided by the embodiment of the present invention. As Figure 2 shown, the electronic red sign status monitoring system 100 of the railway port freight yard further includes an image detection device 40; the image detection device 40 is used to detect the third distance signal between the electronic red sign 200 in the railway port freight yard and the electronic red sign status monitoring system 100 of the railway port freight yard; the control device 30 is also electrically connected to the image detection device 40, and is used to obtain the third distance signal, and determine the status of the electronic red sign in the railway port freight yard according to the first distance signal, the second distance signal, the third distance signal and the preset distance.

[0045] Specifically, the image detection device 40 may include a camera. By collecting the image information of the electronic red sign 200 at the railway port freight yard and analyzing the edges, contours, and feature points of the electronic red sign 200 in the image, the distance between the electronic red sign 200 at the railway port freight yard and the camera can be detected. Furthermore, the third distance signal between the electronic red sign 200 at the railway port freight yard and the electronic red sign status monitoring system 100 at the railway port freight yard can be detected. The control device 30 can obtain the third distance signal, calculate the average value of the first current distance, the second current distance, and the obtained third distance signal, and determine the average value of the three as the current distance between the electronic red sign status monitoring system at the railway port freight yard and the electronic red sign at the railway port freight yard. Whether the electronic red sign at the railway port freight yard is erected in place is determined according to the current distance and the preset distance. In this way, the accuracy of the distance detection between the electronic red sign status monitoring system at the railway port freight yard and the electronic red sign at the railway port freight yard can be improved, and further the detection accuracy of the status of the electronic red sign at the railway port freight yard can be improved.

[0046] It should be noted that for the convenience of the image detection device 40 to collect the image of the electronic red sign 200 at the railway port freight yard, the image detection device 40 can be arranged on one side close to the back plate 201 of the electronic red sign 200 at the railway port freight yard, and there is no other shielding object in front of the image detection device 40.

[0047] It should be noted that the control device can also determine the dispersion degree of the three distance values according to the variance of the first current distance, the second current distance, and the third distance signal, or determine the deviation degree between the three distance values and the average value of the three according to the standard deviation of the first current distance, the second current distance, and the third distance signal. In this way, the fluctuation situation of the three distance values can be obtained.

[0048] Optionally, continue to refer to Figure 1 , the electronic red sign status monitoring system 100 at the railway port freight yard further includes a housing 50 and a support device 60; both the first signal transmission device 10 and the second signal transmission device 20 are located inside the housing 50 and are both on the side close to the electronic red sign 200 at the railway port freight yard; the support device 60 includes a horizontally distributed part 601 and a vertically distributed part 602 connected to each other, and the vertically distributed part 602 is located between the housing 50 and the horizontally distributed part 601.

[0049] Specifically, both the first signal transmission device 10 and the second signal transmission device 20 are located inside the housing 50. In this way, the housing 50 can protect the first signal transmission device 10 and the second signal transmission device 20 and prevent the external environment from polluting or damaging the two signal transmission devices. The two transmission devices are located on the side close to the electronic red sign 200 at the railway port freight yard to facilitate the detection of the status of the electronic red sign at the railway port freight yard.

[0050] Specifically, the support device 60 is used to support the housing 50 to ensure the stability of the electronic red flag status monitoring system for the railway port freight yard. The support device 60 includes a horizontally distributed part 601 and a vertically distributed part 602 which are connected. The horizontally distributed part 601 can be understood as a bearing pad. The vertically distributed part 602 is located between the horizontally distributed part 601 and the housing 50 to support the housing 50, which is beneficial for the two transmitting devices to detect the status of the electronic red flag in the railway port freight yard.

[0051] Optionally, continue to refer to Figure 1 , along the first direction Y, the extension dimension of the housing 50 is smaller than that of the electronic red flag 200 in the railway port freight yard; along the second direction X, the distance between the housing 50 and the electronic red flag 200 in the railway port freight yard is greater than the extension dimension of the electronic red flag 200 in the first direction Y; the second direction X intersects with the first direction Y.

[0052] Specifically, the first signal transmitting device 10 and the second signal transmitting device 20 can be respectively located at the edge positions of the housing 50. Along the first direction Y, the extension dimension of the housing 50 is smaller than that of the electronic red flag 200 in the railway port freight yard. In this way, it can ensure that the distance between the first signal transmitting device 10 and the second signal transmitting device 20 in the first direction Y is appropriate, preventing the distance between the first signal transmitting device 10 and the second signal transmitting device 20 from being too close or too far, which may affect the detection accuracy of the electronic red flag 200 in the railway port freight yard.

[0053] Specifically, along the second direction X, the distance between the housing and the electronic red flag 200 in the railway port freight yard is greater than the extension dimension of the electronic red flag 200 in the first direction Y. In this way, it can prevent the electronic red flag 200 in the railway port freight yard from causing damage to the housing 50 when it changes from an upright state to an inclined or withdrawn state.

[0054] Optionally, continue to refer to Figure 1 , the electronic red flag status monitoring system 100 for the railway port freight yard further includes a power supply device ( Figure 1 not shown in the figure); the power supply device is electrically connected to the first signal transmitting device 10, the second signal transmitting device 20 and the control device 30 respectively, and is used to supply power to the first signal transmitting device 10, the second signal transmitting device 20 and the control device 30.

[0055] Specifically, the power supply device supplies power to the first signal transmitting device 10, the second signal transmitting device 20 and the control device 30, which can further ensure the normal operation of the first signal transmitting device 10, the second signal transmitting device 20 and the control device 30.

[0056] Specifically, the power supply device includes a lithium battery, and the lithium battery has the advantages of small volume and long service life.

[0057] Optionally, continue to refer to Figure 1 , the first signal transmitting device 10 includes a first ranging radar; the second signal transmitting device 20 includes a second ranging radar.

[0058] Specifically, the first ranging radar sends a first distance signal to the electronic red sign at the railway port freight yard, and the second ranging radar sends a second distance signal to the electronic red sign at the railway port freight yard, so as to determine the status of the electronic red sign at the railway port freight yard through the first distance signal and the second distance signal subsequently.

[0059] Optionally, continue to refer to Figure 1 , along the first direction Y, the extension dimension of the electronic red sign status monitoring system 100 at the railway port freight yard is equal to the extension dimension of the electronic red sign 200 at the railway port freight yard.

[0060] Specifically, along the first direction Y, the extension dimension of the electronic red sign status monitoring system 100 at the railway port freight yard is equal to the extension dimension of the electronic red sign 200 at the railway port freight yard, that is to say, the height of the electronic red sign status monitoring system 100 at the railway port freight yard is the same as that of the electronic red sign 200 at the railway port freight yard. In this way, it is beneficial for the electronic red sign status monitoring system 100 at the railway port freight yard to monitor the status of the electronic red sign 200 at the railway port freight yard and improve the monitoring accuracy.

[0061] Exemplarily, when the height of the electronic red sign status monitoring system 100 at the railway port freight yard is greater than or less than the height of the electronic red sign 200 at the railway port freight yard, the distance signals sent by the first signal transmitting device 10 and the second signal transmitting device 20 are difficult to reach the electronic red sign 200 at the railway port freight yard, which will further affect the monitoring result of the status of the electronic red sign at the railway port freight yard.

[0062] In summary, for the electronic red sign status monitoring system provided by the embodiment of the present invention, there is a point on the line connecting the first signal transmitting device and the second signal transmitting device, and the distance from the first signal transmitting device to this point is known, and the distance from the second signal transmitting device to this point is known. Then, according to the distance from the first signal transmitting device to this point and the first distance signal, the first current distance between this point and the backplane can be determined by the Pythagorean theorem control device. Then, according to the distance from the second signal transmitting device to this point and the second distance signal, the second current distance between this point and the backplane can be determined by the Pythagorean theorem control device. By calculating the average value of the first current distance and the second current distance, the distance between the electronic red sign status monitoring system at the railway port freight yard and the electronic red sign at the railway port freight yard can be obtained, and it can be judged whether the electronic red sign at the railway port freight yard is set up in place according to the current distance and the preset distance, and thus the status of the electronic red sign at the railway port freight yard can be monitored.

[0063] Based on the same inventive concept, an embodiment of the present invention further provides a method for monitoring the electronic red flag status of a railway port freight yard, which is applied to the system for monitoring the electronic red flag status of a railway port freight yard provided in the above embodiment. Figure 3 It is a schematic flowchart of the first method for monitoring the electronic red flag status of a railway port freight yard provided by an embodiment of the present invention. As Figure 3 shown, the method includes:

[0064] S101. Obtain a first distance signal through a first signal sending device and obtain a second distance signal through a second signal sending device.

[0065] Specifically, continue to refer to Figure 1 , both the first signal sending device 10 and the second signal sending device 20 are located on one side close to the backplane 201. The first signal sending device 10 sends a first distance signal S1 to the backplane 201, and the second signal sending device 20 sends a second distance signal S2 to the backplane 201.

[0066] S102. Determine the electronic red flag status of the railway port freight yard according to the first distance signal, the second distance signal, and a preset distance.

[0067] Specifically, continue to refer to Figure 1 , the distance between the first signal sending device 10 and the second signal sending device 20 is known. If there is a point O on the line connecting the first signal sending device 10 and the second signal sending device 20, and the distance between the first signal sending device 10 and the point O is L1, the distance between the second signal sending device 20 and the point O is L2, and the first signal sending device 10 sends a first distance signal S1 to the backplane 201, and the second signal sending device 20 sends a second distance signal S2 to the backplane 201. In the first right triangle formed by the first signal sending device 10, the point O, and the backplane 201, according to the Pythagorean theorem, the control device 30 can determine the first current distance D1 between the point O and the backplane 201; in the second right triangle formed by the second signal sending device 20, the point O, and the backplane 201, according to the Pythagorean theorem, the control device 30 can determine the second current distance D2 between the point O and the backplane 201. Furthermore, the control device 30 can calculate the average value of the first current distance D1 and the second current distance D2, so as to obtain the current distance between the system for monitoring the electronic red flag status of the railway port freight yard and the electronic red flag of the railway port freight yard.

[0068] Specifically, the preset distance can be understood as the distance between the electronic red sign of the railway port freight yard and the state monitoring system of the electronic red sign of the railway port freight yard when the electronic red sign of the railway port freight yard is erected in place, that is, the distance between point O and the backplane 201 when the electronic red sign of the railway port freight yard is erected in place. If the current distance is equal to the preset distance, it indicates that the current electronic red sign of the railway port freight yard is erected in place. If the current distance is greater than or less than the preset distance, it indicates that the current electronic red sign of the railway port freight yard is in the state of evacuation or tilt, and there is a risk that the electronic red sign of the railway port freight yard invades the railway line. At this time, the state monitoring system of the electronic red sign of the railway port freight yard can send an alarm signal for the operation and maintenance personnel to adjust the state of the electronic red sign of the railway port freight yard, so as to ensure that the electronic red sign of the railway port freight yard is erected in place, and to ensure the warning effect and control of the electronic red sign of the railway port freight yard on the safety of the railway line.

[0069] The method for monitoring the state of the electronic red sign of the railway port freight yard provided by the embodiment of the present invention obtains the first current distance between a point in the middle of the two transmitting devices and the backplane through the first signal transmitting device, and the second current distance between the point in the middle of the two transmitting devices and the backplane through the second signal transmitting device. By calculating the average value of the first current distance and the second current distance, the distance between the state monitoring system of the electronic red sign of the railway port freight yard and the electronic red sign of the railway port freight yard can be obtained, and it is judged whether the electronic red sign of the railway port freight yard is erected in place according to the current distance and the preset distance, so as to realize the monitoring of the state of the electronic red sign of the railway port freight yard.

[0070] Optionally, Figure 4 is a schematic flowchart of the second method for monitoring the state of the electronic red sign of the railway port freight yard provided by the embodiment of the present invention. Figure 4 On the basis of the above embodiment, the operations after obtaining the first distance signal through the first signal transmitting device and obtaining the second distance signal through the second signal transmitting device are described. As Figure 4 shown, the method includes:

[0071] S201. Obtain a first distance signal through the first signal transmitting device and obtain a second distance signal through the second signal transmitting device.

[0072] S202. Obtain a third distance signal through the image detection device.

[0073] Specifically, continue to refer to Figure 1, the image detection device 40 may include a camera. By collecting the image information of the electronic red sign 200 at the railway port freight yard and analyzing the edges, contours, and feature points of the electronic red sign 200 in the image, the distance between the electronic red sign 200 at the railway port freight yard and the camera can be detected. Furthermore, the third distance signal between the electronic red sign 200 at the railway port freight yard and the electronic red sign status monitoring system 100 of the railway port freight yard can be detected, and the control device 30 can obtain the third distance signal.

[0074] S203. Determine the status of the electronic red sign at the railway port freight yard according to the first distance signal, the second distance signal, the third distance signal, and the preset distance.

[0075] Specifically, the control device obtains the first current distance between a point in the middle of the two transmitting devices and the backplane through the first signal transmitting device, and the second current distance between this point in the middle of the two transmitting devices and the backplane through the second signal transmitting device. The control device calculates the average value of the first current distance, the second current distance, and the obtained third distance signal, and determines the average value of the three as the current distance between the electronic red sign status monitoring system of the railway port freight yard and the electronic red sign at the railway port freight yard. According to the current distance and the preset distance, it is determined whether the electronic red sign at the railway port freight yard is set up in place. In this way, the accuracy of the distance detection between the electronic red sign status monitoring system of the railway port freight yard and the electronic red sign at the railway port freight yard can be improved, and further the detection accuracy of the status of the electronic red sign at the railway port freight yard can be improved.

[0076] The method for monitoring the status of the electronic red sign at the railway port freight yard provided by the embodiment of the present invention obtains the third distance signal through the image detection device.
