Specifically, the voice control signal can be obtained by acquiring data acquired by a microphone in the vehicle.
The target person specifically refers to a person currently located in the vehicle, and may be any person, a designated person (e.g., a person in a driver seat), or a person satisfying a specific condition.
The duty status information refers to status information used for representing whether the current status of the target person meets the duty requirement of the task required to be performed by the target person. The on-duty status information may specifically include compliance with and non-compliance with the on-duty requirement. When the execution state information meets the duty requirement, the current state of the target person is matched with the execution requirement of the task required to be executed by the target person; and when the execution state information does not meet the requirement on duty, indicating that the current state of the target person does not match the execution requirement of the task required to be executed by the target person. The duty status information may be directly obtained based on the identity of the target person, or may also be obtained information related to the duty status of the target person (e.g., health status information and/or work task scheduling information of the target person), and the current duty status information of the target person is determined according to the information related to the duty status of the target person.
When the duty status information meets the duty requirement, executing step S20; when the execution state information is that the on-duty requirement is not met, the vehicle can be locked to prohibit the personnel who are not met the on-duty requirement from operating the vehicle-mounted equipment.
And step S20, controlling the operation of the vehicle-mounted equipment according to the voice control signal.
Specifically, a control instruction in the voice control signal is extracted, the control instruction is sent to the corresponding vehicle-mounted equipment, and the vehicle-mounted equipment executes the control instruction after receiving the control instruction so as to operate according to the requirement of the control instruction.
According to the control method of the vehicle-mounted equipment, when the on-duty state of the target person in the vehicle is determined to meet the on-duty requirement through the execution state information, the vehicle-mounted equipment is controlled to operate according to the voice control signal of the target person, instead of directly controlling the vehicle-mounted equipment to operate according to the acquired voice control signal, so that the situation that the current person who does not meet the on-duty requirement performs illegal operation and control on the vehicle-mounted equipment is effectively avoided, the use safety of the vehicle is effectively improved, and the execution effect that the target person needs to complete a task is guaranteed.
In this embodiment, before step S10, when the vehicle is started, the identity information of a person in the vehicle may be obtained, the identity information is verified, when the identity information is successfully verified, the person corresponding to the identity information is taken as the target person, and when the identity information is failed to be verified, alarm information is sent. The identity information of personnel in the vehicle can be acquired through means of face recognition, voiceprint recognition, certificate information acquisition and the like, the identity information is compared with prestored identity information in a prestored database, and when prestored identity information which is consistent with the acquired identity information in comparison exists, the identity information is verified successfully; and when the pre-stored identity information which is consistent with the obtained identity information in comparison does not exist, the identity information verification fails. The process of sending the alarm information specifically comprises the steps of sending the identity information failed in verification to a background command center through a private network wireless link, and carrying out emergency handling by specific vehicle management personnel. In addition, the vehicle can be locked while the alarm information is sent, and the illegal person is prohibited from controlling the current vehicle.

In addition, in this embodiment, in order to further improve the safety of the control of the vehicle-mounted device, when more than one person whose identity information is successfully verified currently exists in the vehicle, a person corresponding to the successfully verified identity information is used as a candidate, and among the more than one person, a person currently in a login state in a setting system corresponding to the vehicle is used as the target person. One vehicle corresponds to one setting system. When the vehicle is started, the setting system is started, the personnel using the vehicle can log in the system based on the identity information which is pre-recorded, it needs to be explained that only one personnel (such as a driver) in the vehicle is allowed to log in the system by one vehicle at the same time, and based on the fact, the personnel currently logging in the system is taken as a target personnel among a plurality of personnel with successful identity authentication. Based on this, it is equivalent to that the vehicle-mounted equipment only responds to the voice control command sent by the target person through double verification, and further improvement of the use safety of the vehicle is realized.
Further, in this embodiment, step S20 specifically includes: extracting a control instruction in the voice control signal, and determining target vehicle-mounted equipment corresponding to the control instruction; acquiring encrypted and stored vehicle-mounted equipment data corresponding to the vehicle; decrypting the vehicle-mounted equipment data and extracting equipment identification information of the target vehicle-mounted equipment; and sending the control instruction to the target vehicle-mounted equipment through a safety protocol according to the equipment identification information so as to enable the target vehicle-mounted equipment to execute the control instruction.
