[0002] A geomagnetic detection device is a device buried underground for detecting whether there is a vehicle parked above the ground. Some geomagnetic detection devices also have the function of monitoring the parking posture of vehicles. Geomagnetic detection devices are generally applied in the field of vehicle parking detection and also in the field of traffic condition detection.

[0003] In the field of traffic condition detection, the detection data of the geomagnetic detection device may involve multiple applications. Generally, the detection data of the geomagnetic detection device is selected to be transmitted to a database deployed in the cloud. The database is connected to the servers of multiple parties related thereto for the servers of multiple parties to call the data in the database to achieve the monitoring of traffic condition information by multiple parties.

[0004] In the process of transmitting the detection data of the geomagnetic detection device to the database and the servers of multiple parties, it is easy to be intercepted by a malicious third party. The malicious third party can easily decipher the data information according to the established communication protocol, obtain the detection data of the geomagnetic detection device, and even tamper with the detection data of the geomagnetic detection device, which is not conducive to the security, privacy, application security, and authenticity of traffic condition-related data.

Detailed implementation manners

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0034] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.

[0035] In the present application, the traffic condition-related data are directly sent to multiple servers from the distributed network constructed by the geomagnetic detection device respectively, and the sent data is in an encrypted state, greatly improving the security of data transmission.

[0036] Referring to Figure 1 and Figure 2 , an embodiment of the present application discloses a geomagnetic detection device 1 of a highly secure multi-signal machine dockable. The geomagnetic detection device 1 includes a geomagnetic detection module 11, a key access module 12, a multi-party communication module 13 and a microprocessor 14. Among them, the microprocessor 14 is respectively connected to the geomagnetic detection module 11, the key access module 12 and the multi-party communication module 13.

[0037] When in use, the geomagnetic detection device 1 is buried underground. The geomagnetic detection module 11 is the main functional module of the geomagnetic detection device 1, which is used to detect the condition information above the ground, that is, whether there are vehicles above the ground at the location, the attitude of the vehicle, etc. This condition information is included in the detection data output by the geomagnetic detection module 11. The geomagnetic detection module 11 is a conventional technology in the related art. The geomagnetic detection device 1 in the present disclosure does not involve the improvement of the geomagnetic detection module 11, so the geomagnetic detection module 11 will not be further introduced. The detection data output by the geomagnetic detection module 11 is sent to the microprocessor 14.

[0038] The key access module 12 is used to access key certificate information for the microprocessor 14 to encrypt the detection data according to the key certificate information. The key access module 12 is specifically embodied as a communication module for the microprocessor 14 to connect to the cooperating key acquisition module 2, and then access the key certificate information obtained by the key acquisition module 2. The key access module 12 can be a wired communication module, such as an optical fiber interface, a USB interface, a LAN interface, etc., or a wireless communication module, such as a Bluetooth module, a WiFi module, a mobile communication module, etc. Since the data of wireless communication is easily intercepted, in this disclosure, the key access module 12 is specifically selected as a wired communication module to enable the microprocessor 14 to be connected to the key acquisition module 2 by wired communication.

[0039] The key acquisition module 2 can specifically be selected as a computer for loading key certificate information. To improve the reliability of the key certificate information, the key acquisition module 2 can be connected to the blockchain network. The key certificate information is stored in the blockchain network, and the network is accessible to multiple servers 3 cooperating with the geomagnetic detection device 1. All the multiple servers 3 can adjust the key certificate information, and the adjustment records of the key certificate information are traceable and unmodifiable, so as to improve the reliability of the key certificate information.

[0040] The multi-party communication module 13 enables the geomagnetic detection device 1 to connect to multiple servers 3 and other geomagnetic detection devices 1 cooperating with it. The multi-party communication module 13 can include wired communication interfaces, such as optical fiber interfaces, Ethernet interfaces, USB interfaces, LAN interfaces, etc. The multi-party communication module 13 can also include wireless communication modules, such as NB-LOT modules, WiFi modules, Bluetooth modules, mobile communication modules, GNSS modules. Similarly, to reduce the possibility of the data transmitted between the geomagnetic detection devices 1 and between the geomagnetic detection device 1 and the multiple servers 3 being intercepted, the multi-party communication module 13 specifically includes three LAN interfaces. One of the three LAN interfaces is used to connect to the multiple servers 3 cooperating with it, and the other is used to connect to the geomagnetic detection device 1 cooperating with it.

[0041] When applying the geomagnetic detection device 1 to detect the traffic condition information of the road, a batch of geomagnetic detection devices 1 are distributed and buried in the road. Among all the cooperating geomagnetic detection devices 1, the geomagnetic detection devices 1 that are close to each other geographically are connected through the multi-party communication module 13, so that all the cooperating geomagnetic detection devices 1 form a distributed system. In this distributed system, all the geomagnetic detection devices 1 are directly or indirectly connected. The multiple servers 3 cooperating with it are connected to one of the geomagnetic detection devices 1 in this distributed system, and thus can be connected to all the geomagnetic detection devices 1.

[0042] In this distributed system, all geomagnetic detection devices 1 are divided into multiple preset geographical ranges according to geographical locations. The size of the preset geographical range is determined by the time delay of signal transmission, aiming to ensure that when a geomagnetic detection device 1 in a preset geographical range receives detection data from other geomagnetic detection devices 1, the occurrence times of all the detection data can be considered as occurring simultaneously within an allowable error. There is at least one geomagnetic detection device 1 in each preset geographical range for processing the detection data within the corresponding preset geographical range, so as to construct traffic structured data reflecting traffic condition information based on the detection data within the preset geographical range.

[0043] Specifically, the detection data carries the terminal identifier of the geomagnetic detection device 1, and the terminal identifier can reflect the geographical location of the corresponding geomagnetic detection device 1. When the microprocessor 14 receives the detection data, it can determine the detection data belonging to its own preset geographical range according to the terminal identifier, decrypt these detection data with the secret key certificate information, and then add a timestamp to the decrypted detection data to generate traffic structured data. After generating the traffic structured data, the microprocessor 14 encrypts the traffic structured data according to the secret key certificate information and sends the traffic structured data to the servers 3 of multiple parties through the multi-party communication module 13.

[0044] It should be understood that considering the computational pressure of the encryption process of traffic structured data, multiple pieces of traffic structured data with adjacent timestamps can be encrypted together to form an encrypted traffic structured data packet, and the traffic structured data reflecting traffic condition information is sent to the servers 3 of multiple parties in the form of the traffic structured data packet; considering the sending pressure of traffic structured data, the generated traffic structured data may not be sent out immediately, and the generated traffic structured data can be temporarily stored in a distributed database composed of the storage space of the geomagnetic detection device 1, and the traffic structured data is sent sequentially according to the timestamp.

[0045] The storage space of the geomagnetic detection device 1 can be included in the microprocessor 14 or in the memory connected to the microprocessor 14. In this disclosure, the microprocessor 14 is connected to a memory 15, and the memory 15 is used to store traffic structured data.

[0046] In addition, to ensure the reliability of the traffic structured data processing process and avoid the efficiency waste caused by repeated processing of the same detection data, at least two preset numbers of geomagnetic detection devices 1 can be provided in each preset geographical range to execute the process of constructing traffic structured data based on the detection data. The preset number can specifically be selected as two.

[0047] Of course, to ensure the lifespan of the microprocessor 14, the task of constructing traffic structured data based on the detection data can be distributed to the microprocessors 14 of all the geomagnetic detection devices 1 within the preset geographical range, or the microprocessors 14 of all the geomagnetic detection devices 1 within the preset geographical range can perform this processing task in sequence, so as to avoid premature damage of a single microprocessor 14 due to excessive load.

[0048] Similarly, to ensure the reliability of the storage process of traffic structured data and avoid waste of storage space caused by duplicate storage of the same traffic structured data, a piece of traffic structured data can be stored in at least two preset numbers of memories 15 in the distributed system. The preset number is also specifically selected as two.

[0049] After the geomagnetic detection device 1 sends the traffic structured data to multiple servers 3, the multiple servers 3 can decrypt the traffic structured data according to the key certificate information obtained from the blockchain network to obtain the traffic condition information therein, and utilize the traffic structured data to control terminal devices such as traffic lights.

[0050] After the server 3 successfully receives the traffic structured data, it will feedback a successful reception instruction encrypted according to the same key certificate information to the distributed system formed by the geomagnetic detection device 1. The successful reception instruction carries the timestamp information of the traffic structured data. After the distributed system formed by the geomagnetic detection device 1 receives the successful reception instruction, it deletes the corresponding traffic structured data information in the distributed system according to the timestamp information carried by the successful reception instruction to ensure the reuse of the storage space of the distributed system.

[0051] The geomagnetic detection device 1 with high security and multi-signal machine docking in the present disclosure has the following advantages:

[0052] 1. It can realize the construction of a distributed system with functions such as acquisition, processing, and storage of detection data, without relying on a cloud database as an intermediate node between the geomagnetic detection system and multiple servers 3 to store traffic condition-related data, reducing the data transmission nodes, and thus reducing the possibility of data leakage.

[0053] 2. The data of the interaction between the geomagnetic detection devices 1 and the interaction between the geomagnetic detection device 1 and multiple servers 3 are all in an encrypted state, and the traffic structured data temporarily stored in the distributed system constructed by the geomagnetic detection device 1 is in an encrypted state, which is conducive to better ensuring the security of the data.

[0054] 3. It can improve the reliability of the traffic structured data processing process and the storage process, and the storage space of the distributed system can be reused. The processing pressure of each geomagnetic detection device 1 is basically the same, which is beneficial to ensuring the good operation of the entire distributed system.

[0055] The embodiment of the present application also discloses a geomagnetic detection system constructed based on the above-mentioned geomagnetic detection device 1.

[0056] Refer to Figure 2 , the geomagnetic detection system includes a distributed system formed by a plurality of geomagnetic detection devices 1, and also includes multiple servers 3, and the multiple servers 3 are connected to the distributed system.

[0057] It can be understood that the geomagnetic detection system can already be implemented by those skilled in the art based on the above disclosure of the geomagnetic detection device 1. For the sake of simplicity of the specification, no repeated description is made here.

[0058] The above description is only a preferred embodiment of the present application and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of disclosure involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the foregoing disclosure concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in the present application.
