The software system includes: the software-defined remote control operating system comprises a real-time operating system as a bottom-layer environment, the operating system environment is Type2 virtualization, and not only is compatible with existing non-real-time applications (advanced algorithms such as graphic processing, a database, machine vision, artificial intelligence and the like) provided, but also the scanning period of an internal program of the operating environment system of the high-real-time application can be preset time (the preset time can be set by a user according to actual conditions, such as 1 millisecond, and the embodiment does not limit the preset time), shared memory communication between the non-real-time operating environment and the real-time system operating environment is provided, the non-real-time operating environment can be independently restarted, and the requirement of fusion of multiple types of services can be met.

The 1 AI server 102 can control a plurality of operation platforms 101 and intelligent analysis of personnel intrusion, and can improve the safety production on site. In the present embodiment, the ground station 10 is configured with two AI servers 102, one of which serves as a backup server.

In the present embodiment, the on-board terminal 11 includes a crown block 111 and a second switch 112.

The first switch 103 and the second switch 112 can receive and forward data to the terminal device through message exchange, and in this embodiment, the first switch 103 and the second switch 112 are machines for performing message exchange between the ground station 10 and the vehicle-mounted terminal 11.

The console is used for sending the control instruction to the AI server through the first switch after acquiring the control instruction input by the user.

The control command may be a command for controlling the overhead traveling crane, which is input from the user on the operation console, based on the actual operation state of the overhead traveling crane. For example, the control command may be a parking command, that is, a crown block is remotely controlled to perform a parking operation.

Specifically, a user inputs a control instruction in an operation console in the ground station, and after the operation console obtains the control instruction input by the user, the control instruction is sent to the AI server in the ground station through the first switch.

The AI server is used for sending the control instruction to the overhead traveling crane through the first switch and the second switch.

Specifically, the AI server is connected with the overhead traveling crane through the first switch and the second switch, and after receiving the control command sent by the console, the AI server sends the control command to the overhead traveling crane at the vehicle-mounted end through the first switch and the second switch.

The overhead traveling crane is used for receiving the control instruction sent by the AI server and executing the control instruction.

Specifically, the overhead traveling crane receives the control instruction sent by the AI server, and executes the control instruction to complete the operation content corresponding to the control instruction. In the actual operation process, each overhead traveling crane is provided with 1 wireless receiving device, the working frequency of the wireless receiving device is 5.8GHZ, and a PF antenna or an external antenna is arranged inside the overhead traveling crane.

The embodiment of the invention designs a crown block remote control system, which comprises a ground station and a vehicle-mounted end, wherein an operation console in the ground station sends a control instruction to an AI server in the ground station through a first switch in the ground station after acquiring the control instruction input by a user; an AI server in the ground station sends a control instruction to an overhead traveling crane in the vehicle-mounted end through a first switch in the ground station and a second switch in the vehicle-mounted end; and the crown block in the vehicle-mounted end receives the control command sent by the AI server in the ground station and executes the control command to complete the interaction between the ground station and the vehicle-mounted end.

Furthermore, the overhead traveling crane is also used for acquiring the field video data and sending the field video data to the operation console through the first switch and the second switch.

It should be explained that the field video data may be environmental video data around the overhead traveling crane collected by a camera arranged on the overhead traveling crane when the overhead traveling crane performs work at the work site.

Specifically, the overhead traveling crane acquires field video data when performing operation on an operation field, and transmits the field video data to an operation console in the ground station through the first switch and the second switch.

Further, the AI server is also used for a virtual real-time operating system and a non-real-time operating system, and the number of the real-time operating systems is the same as the number of the operating stations.

In this embodiment, the AI server may be an AI server of an X86 architecture, and multiple real-time operating systems are virtualized by using a unified X86 architecture hardware platform, where the number of the real-time operating systems is the same as the number of the operating stations, so that resource allocation as needed is realized, and a cooperative control integrated management and control platform of the ground station and the overhead traveling crane in the vehicle-mounted terminal is created. The non-real-time operating system can be a Windows system, a Unix system, a Linux system and other systems, and the most common operating system in the learning process is a general operating system, namely the Windows system, the Unix system, the Linux system and other systems, which are developed from a time-sharing operating system. The basic design principle of the time-sharing operating system is as follows: the average response time of the system is shortened as much as possible, the throughput rate of the system is improved, and service is provided for as many user requests as possible in unit time. Thus, compared to a real-time operating system, a non-real-time operating system pays more attention to the average performance of the system, and in terms of response time, the non-real-time operating system pays more attention to the average response time of all tasks, that is, it pays more attention to the average response time of all tasks and does not pay more attention to the response time of a single task, and for a single task, pays more attention to the average response time of each execution and does not pay more attention to the response time of a specific execution. Windows, the most commonly used general-purpose operating system, supports systems to manage multi-user, multi-process system resources. Different from a kernel preemption mechanism of a real-time operating system, the kernel of the time-sharing operating system cannot be preempted, and no matter what task the priority is, the task can be executed only after the current CPU task is finished or the current task is actively quitted. Therefore, the most direct difference between the non-real-time operating system and the real-time operating system is that: when the kernel is in a relatively consumed state, the processing delay of the non-real-time operating system is increased, and even the final time limit of the execution of the task with the highest priority cannot be guaranteed.

Specifically, the AI server may virtualize a real-time operating system and a non-real-time operating system, where the number of real-time operating systems is the same as the number of operating stations.

In the actual operation process, the AI server is a 6-core server, a real-time operating system is virtualized by 2 cores, a non-real-time operating system is virtualized by 4 cores, each core can virtualize 7 real-time operating systems, and the number of the virtualized real-time operating systems is the same as that of the operating platforms.

In this embodiment, the non-real-time operating system may be configured to identify live video data acquired by the overhead traveling crane, and the specific identification content may include: personnel intrusion, helmet identification, vehicle identification, smoke and fire identification, work clothes identification, off duty identification, smoking identification and the like.

The reminding information may be information for reminding the user by the AI server according to an identification result obtained by identifying the live video data. Illustratively, the reminding information can be reminding words, alarm sound or the like.
