Description

Technical Field

[0001] The present application relates to a roadside monitoring system, and more particularly to a roadside equipment surge protection monitoring system and a road-cloud system. Background Art

[0002] The roadside system V2X equipment includes RSU, MEC, radar, camera, pan / tilt motor, traffic light, etc., which are installed on roadside poles on both sides of the road. The power supply of each device comes from the AC and DC power supplies in the roadside pole bracket box.

[0003] The lightning surge protection function of the roadside system is achieved through lightning rods, PE ground connection, multi-level surge protectors in the pole box, backup protectors, and surge protection designs of the internal terminals of each V2X product. Since the roadside V2X equipment is in a long-term power supply operation state, and the surge protection capabilities of various products vary, the failure of the surge protector cannot be known, so it is impossible to prevent the further deterioration after the failure of the surge protector, resulting in passive power failure or damage to the V2X equipment related to the power supply system, which causes the V2X product to be disconnected or malfunction. Only then can the relevant personnel determine that the roadside system has failed due to lightning surge, and then more manpower and material resources are needed to check and replace the disconnected and damaged equipment, which will affect the normal use of the roadside system.

[0022] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0023] This embodiment provides a roadside equipment surge protection monitoring system, which can be applied to a roadside system to perform surge monitoring on the equipment in the roadside system, and the roadside equipment of the surge protection monitoring system is used as the target roadside equipment. The roadside equipment uses the vehicle to everything (V2X) technology to monitor the road surface and exchange vehicle-to-vehicle data.

[0024] like Figure 1 As shown, the surge protection monitoring system includes: a surge protector 1, connected to the power supply end of the target roadside equipment. The surge protector 1 includes a surge protection device 11, a tripping device 12 and a remote signal switch 13. When the surge protection device 11 fails, the tripping device 12 is triggered to produce a mechanical action, and the mechanical action of the tripping device 12 drives the remote signal switch 13 to produce a mechanical disconnection.

[0025] The surge protector 1 can adopt the currently available devices, wherein the surge protection device 11 has the function of surge protection. The existing surge protector 1 provided with the tripping device 12 and the remote signal switch 13 is used in the monitoring system of this embodiment. Alternatively, the tripping device 12 and the remote signal switch 13 can also be designed according to the existing technology to trigger the tripping device 12 to produce mechanical action when the surge protection device 11 fails, and the tripping device 12 produces mechanical action to drive the remote signal switch 13 to produce mechanical disconnection.

[0026] For example, the surge protection device 11 is composed of a fuse resistor and a switch. When the current is too large, the fuse resistor is disconnected, causing the switch to be disconnected.

[0027] For example, the trip device 12 may be an electromagnet device, and when the switch is disconnected, the magnetism of the trip device 12 disappears, causing the remote signal switch 13 to be mechanically disconnected. Alternatively, the trip device 12 may be a spring, which is in a stretched state under normal conditions and contracts when the surge protection device 11 fails.

[0028] The remote signal switch in the surge protector is connected to the transceiver loop signal path of the target roadside device. There can be one surge protector 1 or at least two. When there is one surge protector 1, the remote signal switch 13 in the surge protector 1 is directly connected to the transceiver loop signal path of the target roadside device. When the remote signal switch 13 is disconnected, the transceiver loop signal path is disconnected, and a surge protection failure alarm signal is generated. The failure alarm signal can be sent to the cloud platform through the communication module.

[0029] When there are at least two surge protectors 1, the remote signal switches 13 in each surge protector 1 are connected in series and connected to the transceiver loop signal path of the target roadside equipment. When any remote signal switch 13 is disconnected, the transceiver loop signal path is disconnected, and a surge protection failure alarm signal is generated.

[0030] One implementation method is: the target roadside equipment is an edge computing unit (Multi-Access / Mobile Edge Computing, referred to as MEC). The remote signal switch 13 is specifically connected to the external protection IO interface of the MEC, and forms a transceiver loop signal path with the MEC. The MEC can be the MEC in the original roadside system, or it can be a separately set MEC. The remote signal switch in a surge protector 1 is connected to the MEC to form a transceiver loop signal path, or the remote signal switches 13 in at least two surge protectors 1 are connected in series and connected to the MEC to form a transceiver loop signal path. When any remote signal switch 13 is disconnected, the transceiver loop signal path is disconnected, and the MEC recognizes this signal change and generates a surge protection failure alarm signal.

[0031] The technical solution provided in this embodiment is that the roadside equipment surge protection monitoring system includes a surge protector connected to the power supply end of the target roadside equipment; wherein the surge protector includes a surge protection device, a tripping device and a telesignaling switch. When the surge protection device fails, the tripping device is triggered to produce a mechanical action, driving the telesignaling switch to disconnect; the telesignaling switch in the surge protector is connected to the transceiver loop signal path of the target roadside equipment; when the telesignaling switch is disconnected, the transceiver loop signal path is disconnected, and a surge protection failure alarm signal is issued, which can timely identify the degradation or failure of the surge protector, so that the operator can go to the roadside system to check the surge protector and replace it in time.

[0032] Based on the above technical solution, Figure 2 As shown, the monitoring system also includes: a failure indicator device 14, which has a normal mark and a failure mark, and displays a normal mark in a normal state; after the trip device produces a mechanical action, it drives the failure indicator device to display a failure mark. Based on this scheme, a surge protector 1 including a trip device 12, a remote signal switch 13, and a failure indicator device 14 in the existing technology can be used. Or it can also be implemented according to known technical designs,

[0033] This embodiment provides a specific implementation method: the failure indication device 14 includes: a first indicator card and a second indicator card of different colors, the first indicator card is used as a failure mark, and the second indicator card is used as a normal mark. Under normal device conditions, the second indicator card blocks the first indicator card, and the operator can only see the second indicator card, indicating that the surge protector is normal. When the trip device 12 produces a mechanical action, it drives the second indicator card to move away, revealing the first indicator card. When the operator sees the first indicator card, he believes that the surge protector has failed. For example: if the first indicator card is red and the second indicator card is green, the operator will regard green as the normal surge protector and red as the failure of the surge protector.

[0034] For example, the failure indicator device 14 is implemented by an electromagnet or a spring. When the trip device is normal, the failure indicator device 14 is powered on to generate magnetic force to attract the second indicator card to the position where the first indicator card is blocked, and the second indicator card is exposed. The operator observes the green second indicator card and believes that no surge protection failure has occurred. When the trip device produces mechanical action, the failure indicator device 14 is powered off, the magnetic force disappears, the second indicator card is removed, and the first indicator card is exposed. The operator observes the red first indicator card and believes that a surge protection failure has occurred.

[0035] The surge protector 1 is provided with remote signal terminals, and a remote signal switch 13 is connected between the remote signal terminals. When the remote signal switch 13 is closed, the remote signal terminals are connected; when the remote signal switch 13 is opened, the remote signal terminals are disconnected. The remote signal switch 13 adopts a mechanical on-off mechanism, which can be realized by using known technology.

[0036] Furthermore, the overcurrent fuse in the above-mentioned surge protection device 11 is connected in parallel to the power supply end of the target roadside equipment. When the surge protection of the surge protector 1 fails, it will not affect the normal power supply of the target roadside equipment, nor will it affect the normal operation of the target roadside equipment.

[0037] Furthermore, it also includes: a communication module and an antenna, and the communication module is electrically connected to the MEC and the antenna respectively. MEC sends the surge protection failure alarm signal to the cloud platform through the communication module and the antenna, and generates a surge protector abnormality alarm on the cloud platform, so as to realize remote monitoring of the surge protection failure of the target roadside equipment, and timely know whether the lightning surge protection capability of the target roadside equipment is in a normal state, so as to facilitate timely notification of relevant personnel to install and replace the surge protector, thereby avoiding the risk of further power failure or deterioration and damage of the V2X target roadside equipment in the event of a surge protector failure, and reducing the project maintenance cost. The communication module can be specifically integrated on the circuit board of the MEC.

[0038] In the above scheme, the remote signal switch 13 in each surge protector 1 is connected in series to the signal loop path of DI and DO of MEC in a hand-in-hand manner to achieve an "and" relationship. For example: the initial state of the remote signal switch is closed, and the communication on the transceiver loop signal path is normal; as long as any surge protection device 11 fails, the remote signal switch is disconnected, and the communication on the transceiver loop signal path is abnormal. The remote cloud platform can receive the abnormal alarm signal and then send the information to the operator. The operator can lock the device with abnormal surge protection in time, and then lock the target roadside device with failed surge protection by observing the failure indication device 14, and complete the replacement in time to avoid further deterioration of the fault.

[0039] Based on the above technical solution, this embodiment provides a road-cloud system, including: a pole box, a target roadside device and an external roadside device. The pole box is arranged on a roadside pole, and the target roadside device is arranged in the pole box. The external roadside device is located outside the pole box, for example, on a roadside pole.

[0040] The Road-Cloud system also includes a roadside equipment surge protection monitoring system provided by any of the above contents, which is correspondingly connected to the power supply end of the target roadside equipment.

[0041] Figure 1 and Figure 2 An implementation method is as follows: the target roadside equipment and the surge protection monitoring system are both arranged in the pole box. The target roadside equipment is integrated with a communication module, the communication module is arranged in the pole box, the antenna is arranged outside the pole box, and the antenna is connected to the communication module through a coaxial line. The communication module is specifically an MEC communication module, which is integrated on the circuit board of the MEC. The antenna is specifically a 4G / 5G antenna. The road-cloud system also includes a cloud platform, and the antenna is connected to the cloud platform in communication.

[0042] Another implementation method: the external roadside equipment is provided with a communication module, the target roadside equipment is connected to the communication module of the external roadside equipment via a network cable, and the communication module is connected to the cloud platform via an antenna.

[0043] When the roadside pole only includes a vertical pole, the above-mentioned pole holding box and external roadside equipment are all arranged on the vertical pole. Figure 3 and Figure 4 As shown, another implementation is: the roadside pole includes: a vertical pole and a cross bar arranged on the top of the vertical pole, and the pole box is arranged on the vertical pole; some target roadside equipment is arranged in the pole box, and the remaining target roadside equipment is arranged on the cross bar. The surge protection monitoring system can be integrated in the pole box, or partially arranged in the pole box, and the rest is arranged on the cross bar. The communication module and the antenna are arranged on the cross bar, and the communication module is connected to the MEC located in the pole box through an Ethernet cable. The communication module is specifically an RSU communication module, which is integrated on the circuit board of the RSU. The antenna is specifically a 4G / 5G antenna. RSU is the abbreviation of Road Side Unit.

[0044] The above-mentioned communication module can adopt the communication module in the road side system in the existing technology, and the connection with MEC and antenna and the data communication method can be implemented by referring to the existing technology.
