As shown in fig. 1, the present embodiment provides an electronic apparatus 1 including: at least one processor 11 and a memory 12, one processor being exemplified in fig. 1. The processor 11 and the memory 12 are connected by a bus 10, and the memory 12 stores instructions executable by the processor 11 and the instructions are executed by the processor 11.
In an embodiment, as shown in fig. 2, the embodiment provides a terminal control system, which includes a cloud server 201 and a terminal 202. The cloud server 201 may be implemented by the electronic device 1, and the terminal 202 may be an unmanned vehicle, a robot, a smart arm, or the like. In this embodiment, the terminal 202 is described as an unmanned vehicle, the electronic device 1 may perform real-time communication with the unmanned vehicle through the internet, when the unmanned vehicle has a fault, the fault information may be uploaded to the cloud server 201 in real time, the cloud server 201 acquires the fault information sent by the terminal 202, and determines whether the terminal 202 has a condition for performing mechanical movement according to the fault information, and when the terminal 202 has the condition for performing mechanical movement, a control instruction corresponding to the terminal 202 is generated according to the fault information, and the control instruction is sent to the terminal 202. Thereby enabling guiding the malfunctioning terminal 202 for mechanical movement.
Please refer to fig. 3, which is a control method of the terminal 202 according to an embodiment of the present application, and the method may be executed by the electronic device 1 shown in fig. 1 as the cloud server 201, and may be applied to the terminal control system 20 shown in fig. 2, so that the cloud server 201 generates a control instruction for guiding the terminal 202 to perform mechanical movement according to the fault information uploaded by the terminal 202. The method comprises the following steps:
step 301: the cloud server 201 obtains the fault information sent by the terminal 202.
In this step, the terminal 202 may be an unmanned vehicle, and when an automatic driving system of the unmanned vehicle fails and the unmanned vehicle cannot control the vehicle to move forward through its own control system, corresponding failure information is generated and uploaded to the cloud server 201, and the cloud server 201 receives the failure information in real time. The failure information includes, but is not limited to: identity information and a fault code of the unmanned vehicle.
Step 302: the cloud server 201 determines whether the terminal 202 has a condition for performing mechanical movement based on the failure information.
In this step, after receiving the fault information, the cloud server 201 processes the fault information, and determines whether the terminal 202 has a condition for performing mechanical movement, if so, step 303 is performed, otherwise, step 304 is performed.
Step 303: the cloud server 201 generates a control instruction corresponding to the terminal 202 according to the fault information, and sends the control instruction to the terminal 202.
In this step, when the terminal 202 has the condition for performing the mechanical movement, it is described that the components of the terminal 202 for the mechanical movement can operate normally, and the mechanical movement cannot be controlled by the control system of the terminal 202 itself. For example, the components of the unmanned vehicle, such as wheels, a steering wheel, and a driving motor, which are used for mechanical movement, can also work normally, but an automatic driving system for sending a control instruction is broken, at this time, the cloud server 201 can generate a control instruction for controlling the terminal 202 according to the specific content corresponding to the fault information, and send the control instruction to the terminal 202.
Step 304: the cloud server 201 issues a prompt.
In this step, when the terminal 202 does not have the condition for performing mechanical movement, it is described that mechanical parts of the terminal 202 may be damaged, so that the terminal 202 cannot be moved normally. For example, the wheels of the unmanned vehicle are broken, and at this time, the cloud server 201 cannot guide the unmanned vehicle to mechanically move, and can send out a prompt in real time, so that the worker can timely perform on-site processing according to the prompt information.
In the method for controlling the terminal 202, the cloud server 201 obtains the fault information sent by the terminal 202 in real time, determines whether the terminal 202 has the capability of mechanical movement, and generates the control instruction for the terminal 202 when the terminal 202 has the capability of mechanical movement, so that after the control instruction is sent to the terminal 202, the terminal 202 with the fault can execute the corresponding mechanical action according to the control instruction.
Please refer to fig. 4, which is a control method of the terminal 202 according to an embodiment of the present application, and the method may be executed by the electronic device 1 shown in fig. 1 as the cloud server 201, and may be applied to the terminal control system 20 shown in fig. 2, so that the cloud server 201 generates a control instruction for guiding the terminal 202 to perform mechanical movement according to the fault information uploaded by the terminal 202. The method comprises the following steps:
step 401: the cloud server 201 obtains the fault information sent by the terminal 202. See the description of step 301 in the above embodiments for details.
Step 402: the cloud server 201 analyzes the fault code in the fault information.
In this step, the fault code in the fault information represents the specific fault content of the terminal 202, and the identity information and the fault code corresponding to the terminal 202 can be obtained at least by performing data analysis on the fault information.
Step 403: the cloud server 201 analyzes the fault component in the terminal 202 according to the fault code.
In this step, the fault code may characterize a specific faulty component of the terminal 202, and a specific fault attribute of the faulty component, and the like. By analyzing or looking up the fault code, the specific faulty component where the terminal 202 is faulty can be obtained. For example, by analyzing the fault code uploaded by the unmanned vehicle, the faulty component of the unmanned vehicle can be known.
Step 404: the cloud server 201 determines whether the faulty component is a preset mechanical component, where the preset mechanical component is a component used by the terminal 202 for mechanical movement.
In this step, the preset mechanical components can be set according to practical applications, which are generally necessary components for supporting the terminal 202 for mechanical movement, such as wheels, driving motors, steering gears, etc. of the unmanned vehicle. A preset mechanical component and its corresponding mechanical performance and mechanical function may be combined into an association table, and it is determined whether the faulty component determined in step 403 is in the preset association table, if so, step 412 is performed, and if not, step 405 is performed. Step 405: the cloud server 201 sends a collection instruction to the terminal 202.
In this step, when the faulty component is not a preset mechanical component, it indicates that the terminal 202 has a condition for performing mechanical movement, and the fault information may include current location information of the terminal 202, such as GPS positioning information. The cloud server 201 first establishes a high-bandwidth communication link with the terminal 202, for example, the unmanned vehicle still has a mechanical movement condition, the cloud server 201 may establish a high-bandwidth communication link with a controller whose vehicle end has a vehicle control authority, then, generate a corresponding information acquisition instruction, and send the acquisition instruction to the controller of the vehicle end through the communication link. The acquisition instruction at least includes the type of information to be acquired, an acquisition module which is responsible for acquiring the information and needs to be started, and the like.
Step 406: the terminal 202 collects the environmental information of the current position based on the collection instruction, and sends the environmental information to the cloud server 201.
In this step, the terminal 202 acquires the relevant information after receiving the acquisition instruction, and uploads the relevant information to the cloud server 201. For example, after receiving the acquisition instruction, the driverless vehicle may first perform initialization processing on the vehicle-end acquisition module. Assuming that the information to be acquired in the acquisition instruction is environmental information of the current position, the acquisition module may be a camera, an ultrasonic sensor, or other device installed at the vehicle end. The environmental information of the current position of the vehicle end is acquired through the acquisition module, and the environmental information is uploaded to the cloud server 201.
Step 407: the environmental information of the current location collected by the terminal 202 is received.
In this step, the terminal 202 acquires the environmental information of the current position of the vehicle end through the acquisition module, and uploads the environmental information to the cloud server 201, and the cloud server 201 can receive the environmental information in real time.
Step 408: the cloud server 201 determines a stop point of the terminal 202 according to the current position and/or the environment information.
In this step, the environment information may include at least: the environmental image information and the ultrasonic information of the terminal 202 at the current position. Taking an unmanned automobile as an example, the identification of the lane line of the current position of the vehicle end can be analyzed by performing image processing on the environmental image information of the current position of the vehicle end, and the roadside safety position, namely the parking point, closest to the vehicle is found.
Step 409: the cloud server 201 calculates a moving route of the terminal 202 from the current position to the stop point according to the environment information.
In this step, after finding the stop point, the cloud server 201 continues to perform image processing and analysis on the image information, and then finds a lane closest to the stop point, and calculates a lateral distance between the current position of the vehicle end and the lane. Therefore, the transverse distance of the vehicle moving to the lane can be obtained, and the moving route of the vehicle guide stop point can be further obtained.
Step 410: the cloud server 201 generates a control instruction corresponding to the movement route.
In this step, after the movement route of the vehicle is calculated, the cloud server 201 generates a control instruction corresponding to the movement route, and the control instruction can guide the terminal 202 to move to the stop point.
In one embodiment, the control instructions include, but are not limited to: one or more of a moving distance, a steering angle, and a moving speed of the terminal 202.
Step 411: the cloud server 201 sends the control instruction to the terminal 202.
In this step, the cloud server 201 may send the control instruction to the terminal 202 in real time through a communication link established with the terminal 202, so that the terminal 202 executes a corresponding mechanical action according to the control instruction.
In an embodiment, in the moving process of the unmanned vehicle, the cloud server 201 may detect the position of the obstacle in the image information by analyzing each frame of video data in the image information, and determine the moving angle of the vehicle by combining the obstacle information analyzed by the ultrasonic information, so as to avoid the obstacle, thereby ensuring that the vehicle moves to the stop point on the roadside safely.
Step 412: when the terminal 202 does not have the condition for performing the mechanical movement, the cloud server 201 issues a prompt. See the description of step 304 in the above embodiments for details.
An embodiment of the present invention further provides a non-transitory electronic device readable storage medium, including: a program that, when run on an electronic device, causes the electronic device to perform all or part of the procedures of the methods in the above-described embodiments. The storage medium may be a magnetic Disk, an optical Disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a Flash Memory (Flash Memory), a Hard Disk (Hard Disk Drive, abbreviated as HDD), a Solid State Drive (SSD), or the like. The storage medium may also comprise a combination of memories of the kind described above.
