In the following, nouns involved in the embodiments of the present application are explained for the convenience of readers' understanding.

(1) Blockchain

In the blockchain platform, there are two kinds of databases, one is the chain database for storing blocks and transaction data, and the other is the user database for synchronizing user table transaction data. Databases in the blockchain platform include relational database management systems (MySQL) and lightweight databases (SQLite).

A blockchain is a chain of blocks one after another. Certain information is stored in each block, and they are connected into a chain according to the time sequence of their generation. This chain is saved in all servers, as long as one server in the whole system can work, the whole blockchain is safe. These servers are called nodes in the blockchain system, and they provide storage space and computing power support for the entire blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes, and these nodes are usually in the hands of different subjects, so it is extremely difficult to tamper with the information in the blockchain thing. Compared with traditional networks, blockchain has two core features: one is that data is difficult to tamper with, and the other is decentralization. Based on these two characteristics, the information recorded in the blockchain is more authentic and reliable, which can help solve the problem of people's mutual mistrust.

The blockchain platform is based on the underlying trust list mechanism. The trust list is configured in the configuration file to support multiple transaction types, and all changes to the state on the chain are completed through transactions. The blockchain platform supports national secret algorithms. The blockchain platform supports account-level CA certificates. After the CA verification function is enabled, accounts without certificates cannot initiate transactions. Built-in smart contract Ethereum (Ethereum, EVM) virtual machine, and expands the curly braces language (Solidity) command; supports table transaction synchronization, after the table-related transaction consensus is passed, it can be automatically synchronized to the database, or can be re-written when needed Synchronize; support table data query function, transaction data is synchronized to the database for user retrieval, and users with query authority can perform complex queries on data.

The blockchain platform supports the hypertext transfer protocol (Hyper Text Transfer Protocol, HTTP) interface and the full-duplex communication protocol (Websocket) interface in the format of the remote procedure call transfer protocol (Json-Rpc), and implements it based on the full-duplex communication protocol interface Object-oriented programming language (Java), development platform (Node.js) application programming interface (API) in two languages and signature libraries in multiple languages.

According to the degree of centralization, blockchain is divided into three branches: public chain, alliance chain and private chain. The public chain is a completely decentralized blockchain type. In the public chain, there is no central server, and there is no official organization or management agency. All nodes on the chain can freely conduct transactions without being controlled by other nodes. Each Consistency is maintained between nodes through a consensus mechanism. Private chain is a type of centralized blockchain. All permissions are controlled by centralized organizations and institutions. It is generally applied to internal systems of enterprises. Its operating rules are set according to the specific requirements of enterprises. The consortium chain is a type of multi-centralized blockchain, which allows authorized nodes to join the network. Each node usually has a corresponding entity organization. Each organization manages one or more nodes, and its data only allows the system Different institutions in the country can read, write and send according to their permissions. The appropriate blockchain branch can be selected according to the actual production environment.

(2) Smart contract

A smart contract is a digital contract stored on a blockchain that is automatically executed when pre-determined terms and conditions are met. Since the blockchain is open, transparent, and difficult to tamper with, putting smart contracts on the blockchain can effectively reduce the cost of trust between devices. The verification nodes on the blockchain verify the signature of the event to ensure its validity. After most verification nodes reach a consensus on the event, the smart contract is successfully executed.

(3) Traffic operation monitoring and dispatching center

The Transportation Operations Coordination Center (TOCC) revolves around the construction of a comprehensive transportation coordination system, implements traffic operation monitoring, forecasting and early warning, provides traffic information services to the public, carries out dispatch coordination of various modes of transportation, and provides traffic Information assurance for administrative management and emergency response.

Road network monitoring is the core component of the comprehensive traffic operation monitoring and coordination system. It has realized the three major road networks covering urban roads, expressways, and national and provincial arterial lines; the three major urban transportation modes of rail transit, ground public transportation, and taxis; The comprehensive operation monitoring and coordinated linkage of the three major intercity transportation modes of passenger transportation and civil aviation passenger transportation have played a prominent role in government decision-making, industry supervision, business operations, and people's travel in comprehensive transportation. Urban road network monitoring and early warning mainly obtains the real-time operation status of the urban road network through the monitoring and analysis of road network index, road network speed, congested road sections, real-time road conditions and road events, and provides early warning when the traffic index reaches a certain condition.

In the current traffic system, it is the traffic lights that play the core command role. Traffic lights are generally set at road intersections or at places with crosswalks. Traffic lights are used to command vehicles and pedestrians on the road. Vehicles and pedestrians The indication of traffic lights can ensure the safety of vehicles and pedestrians through the intersection. However, in the current traffic system, the switching rules of traffic lights are pre-set, so it will complete the alternate lighting and extinguishing of signal lights according to the preset program, and for intersections, the traffic flow and the flow of people They are not fixed and have a time period. If vehicles and pedestrians always follow the instructions of traffic lights, it is easy to reduce the efficiency of traffic intersections. In addition, traditional traffic lights are designed above the ground, which will be affected by multiple effects in extreme weather, such as heavy rain, mountain fog, etc., and cannot convey traffic signals over long distances.

Most of the existing traffic guidance devices are laid with dedicated lines and powered by municipal power. When traffic accidents or disasters occur in remote areas, it is difficult for the traffic guidance devices to receive signals and the maintenance cost is too high.

When the existing traffic guidance device adjusts the state of the signal light, manual confirmation is required to change the state of the signal light, and the adjustment of the state of the signal light is inefficient. Most of the existing traffic guidance devices are three-dimensional designs above the ground, which cannot remotely prompt vehicles.

In view of this, the application provides a vehicle guidance system. First, the information collection unit in the road traffic device collects the target real-time data of the monitoring point, and sends the target real-time data to the monitoring and early warning device through the information communication device, and then , the monitoring and early warning device determines the target guidance strategy based on the target real-time data. The target guidance strategy is sent to the vehicle guidance unit through the information communication device, and the road traffic device executes the target guidance strategy through the vehicle guidance unit. Compared with the problem of difficult signal reception of existing traffic guidance devices, the vehicle guidance system provided by this application sends real-time target data of monitoring points to monitoring and early warning devices through information communication devices, and sends target guidance strategies to road traffic devices Therefore, the vehicle guidance system provided by this application can greatly improve the efficiency and quality of information transmission.

Since the monitoring and early warning device of the present application determines the target guidance strategy based on the real-time data of the target, the road traffic device The target guidance strategy is executed by the vehicle guidance unit. Therefore, the vehicle guidance system provided by the present application can greatly save labor resources and improve the efficiency of the vehicle guidance system changing strategies.

Fig. 5 is a flow chart of a vehicle guidance method provided by an embodiment of the present application. As shown in Figure 5, the method includes the following steps:

S501. The road traffic device collects the target real-time data of the monitoring point through the information collection unit.

Exemplarily, the target real-time data identifies the road condition of the monitoring point. The target real-time data is image data and video data.

S502. The road traffic device sends the target real-time data to the monitoring and early warning device through the information communication device. Correspondingly, the monitoring and early warning device receives target real-time data from the road traffic device.

In a possible implementation manner, the road traffic device determines the location information of the monitoring point, and sends the location information of the monitoring point to the monitoring and early warning device through the first communication unit.

Exemplarily, the first communication unit obtains the latitude and longitude information of the monitoring point based on its own satellite positioning capability.

S503. The monitoring and early warning device determines a target guidance strategy based on the real-time data of the target.

Among them, the target guidance strategy is used to control the vehicle guidance unit to conduct vehicle guidance.

Exemplarily, the target guidance strategy is to perform vehicle guidance by changing the light color state of the LED device as an example.

When the target real-time data shows that the road is relatively congested, determine the target guidance strategy to indicate that the light color status of the LED device is orange. In the case that the target real-time data is that the road is slow-moving, the target guidance strategy is determined to indicate that the light color status of the LED device is yellow. When the real-time data of the target indicates that the road is clear, determine the target guidance strategy to indicate that the light color status of the LED device is green.

It is understandable that since the monitoring and early warning device is based on the blockchain smart contract technology, the target guidance strategy can be automatically changed according to the real-time data of the target at the monitoring point.

S504. The monitoring and early warning device sends the target guidance strategy to the vehicle guidance unit of the road traffic device through the information communication device. Correspondingly, the vehicle guidance unit of the road traffic device receives the target guidance strategy from the monitoring and early warning device.

Exemplarily, the monitoring and early warning device is based on the block chain network technology, and the target guidance strategy is encrypted on the chain.

S505. The road traffic device executes the target guidance strategy through the vehicle guidance unit.

The roadside block chain server receives the target guidance strategy sent by the information communication device to the vehicle guidance unit. And the roadside blockchain server decrypts the target guidance strategy.

Exemplarily, the target guidance strategy is to perform vehicle guidance by changing the light color state of the LED device as an example. When the target real-time data shows that the road is severely blocked, in response to the target guidance strategy, the light color status of the LED device is red. When the target real-time data shows that the road is relatively congested, in response to the target guidance strategy, the light color state of the LED device is orange. When the real-time data of the target is that the road is slow-moving, in response to the target guidance strategy, the light color state of the LED device is yellow. When the real-time data of the target indicates that the road is clear, the light color state of the LED device is green in response to the target guidance strategy.

Based on the above technical solution, the road traffic device collects the real-time target data of the monitoring point through the information collection unit, and sends the real-time target data to the monitoring and early warning device through the information communication device, and then determines the target guidance strategy based on the real-time target data. and guide the vehicle
