Exemplarily, intelligent vehicle-mounted robot mainly comprises bluetooth chip, MCU and LCD display screen, and the bluetooth chip carries out the bluetooth as slave unit and cell-phone APP end and is connected and realize the data transmission function, and the bluetooth chip uses the mode of broadcast to make cell-phone APP end can initiatively search for according to intelligent vehicle-mounted robot's the name of binding.

It should be noted that the expression animation list includes a plurality of expression animations, and the mobile phone APP obtains and displays the expression animation list from the cloud.
In specific implementation, a user can select expression animations to be displayed by the intelligent vehicle-mounted robot according to an expression animation list displayed on a mobile phone screen, and the mobile phone APP terminal responds to selection operation of the user based on the expression animation list, so that the expression animations required to be transmitted to the intelligent vehicle-mounted robot by the mobile phone APP terminal are determined.
In this embodiment, because the memory space of cell-phone APP end is limited, can't save too much expression animation image and lead to can't provide too much expression animation for the user, and through obtaining expression animation list from the high in the clouds, can provide richer expression animation for the user, intelligent vehicle-mounted robot's expression animation shows also more diversified, and then effectively improves user's whole experience sense.
Step S20: after the intelligent vehicle-mounted robot verifies the transmission starting protocol, whether the intelligent vehicle-mounted robot is successfully verified or not is judged according to the received first data protocol sent by the intelligent vehicle-mounted robot.
It should be noted that, after receiving the transmission start protocol sent by the mobile phone APP, the intelligent vehicle-mounted robot checks the transmission start protocol, and the checking mode may be, but is not limited to, any one or more of parity check, CRC check, LRC check, gray code check, sum check, and xor check, and the checking method of the protocol is not limited herein.
Step S30: and if the received first data protocol sent by the intelligent vehicle-mounted robot is the request data protocol, judging that the intelligent vehicle-mounted robot is successfully verified.
In the specific implementation, the intelligent vehicle-mounted robot receives the start transmission protocol sent by the mobile phone APP terminal and checks the start transmission protocol, if the check is successful, the intelligent vehicle-mounted robot sends a request data protocol to the mobile phone APP terminal, and the mobile phone APP terminal can judge whether the intelligent vehicle-mounted robot successfully checks the start transmission protocol according to the received data protocol, namely, the mobile phone APP terminal can determine that the start transmission protocol is checked successfully after receiving the request data protocol.
Specifically, the request data protocol format is: the protocol header, the protocol length, the protocol type, the animation type, the image sequence number, the check bit and the protocol tail, and the request data protocol are as shown in the following table 2:
| protocol header | Protocol length | Type of protocol | Animation type | Image sequence number | Check bit | Protocol tail |

| 0xEE | 0x06 | 0x21 | 0～0xFFFF | - | - | 0xFE |
TABLE 2
In a specific implementation, whether the first data protocol is the request data protocol may be determined according to a protocol type in the received first data protocol, for example, the protocol type of the request data protocol is 0x21, and if the protocol type in the first data protocol received by the mobile phone APP end is 0x21, the first data protocol may be determined to be the request data protocol.
In one embodiment, if it is received that a first data protocol sent by the intelligent vehicle-mounted robot is a first error protocol, it is determined that the intelligent vehicle-mounted robot fails to verify; and judging whether the steps S10-S40 need to be repeatedly executed according to the sending flag in the first error protocol.
Specifically, the first error protocol format is: protocol header, protocol length, protocol type, error type, send flag, check bits, and protocol trailer, the first error protocol is as shown in table 3 below:
TABLE 3
It should be noted that the first data protocol may be determined to be a first error protocol according to a protocol type in the received first data protocol, for example, the protocol type of the first error protocol is 0x11, and if the protocol type in the first data protocol received by the mobile phone APP end is 0x11, the first data protocol may be determined to be the first error protocol and it may be determined that the verification of the intelligent vehicle-mounted robot fails. After determining that the verification of the intelligent in-vehicle robot fails, whether steps S10 to S40 need to be repeatedly performed may be determined according to a transmission flag in the first error protocol. Illustratively, if the transmission flag in the first error protocol is 0x00, the transmission protocol is stopped, and if the transmission flag in the first error protocol is 0x01, the steps S10 to S40 are repeatedly performed, that is, the transmission start transmission protocol is retransmitted. The reason for starting the transmission protocol check failure may also be determined according to the error type in the first error protocol, for example, when the error type in the first error protocol is 0x00, the reason for the check failure is a case that a protocol error occurs in the starting transmission protocol, when the error type in the first error protocol is 0x01, the reason for the check failure is a check error occurring in the check process, and when the error type in the first error protocol is 0x02, the reason for the check failure may be other reasons.
In specific implementation, the intelligent vehicle-mounted robot receives the start transmission protocol sent by the mobile phone APP terminal and checks the start transmission protocol, if the check fails, the intelligent vehicle-mounted robot sends a first error protocol to the mobile phone APP terminal, and the mobile phone APP terminal can judge whether the start transmission protocol needs to be sent again according to the sending mark received in the first error protocol.
In this embodiment, whether to resend the start transmission protocol is determined by the sending flag in the first error protocol, and the reason for the verification failure is determined by the error type in the first error protocol, so that the situation that the emotive animation image cannot be successfully transmitted due to the failure of one verification can be avoided, the re-verification can be performed according to the reason for the verification failure, and the possibility of the failure of the second verification is reduced.
Step S40: dividing the n frames of expression animation images into a plurality of image data packets, and transmitting the plurality of image data packets by using an image data protocol, so that the intelligent vehicle-mounted robot finishes expression animation display based on the plurality of image data packets.
Specifically, the format of the image data protocol is: the protocol header, the protocol length, the protocol type, the total number of packets, the packet sequence number, the image data, the check bits and the protocol trailer, and the image data protocol is as shown in the following table 4:
| protocol header | Protocol length | Type of protocol | Total number of packets | Packet sequence number | Image data | Check bit | Protocol trailer |
| 1Byte | 2Byte | 1Byte | 2Byte | 2Byte | 0x1～0x1EA | 1Byte | 1Byte |
| 0xEE | 0x07～0x1F0 | 0x02 | a | 0～a-1 | - | - | 0xFE |
TABLE 4
In a specific implementation, n frames of expression animation images can be divided into a image data packets, one image data packet corresponds to one image data protocol, and the corresponding image data packet can be determined according to a packet sequence number in the image protocol. And after the intelligent vehicle-mounted robot receives the a image data protocols, analyzing the image data protocols, and finishing expression animation display according to the data obtained by analysis.
In the embodiment, a starting transmission protocol of an expression animation is sent to an intelligent vehicle-mounted robot, and after the intelligent vehicle-mounted robot verifies the starting transmission protocol, whether the intelligent vehicle-mounted robot successfully verifies is judged according to a received first data protocol sent by the intelligent vehicle-mounted robot; if the first data protocol sent by the intelligent vehicle-mounted robot is the request data protocol, judging that the intelligent vehicle-mounted robot is successfully verified; dividing the n frames of expression animation images into a plurality of image data packets, and transmitting the plurality of image data packets by using an image data protocol, so that the intelligent vehicle-mounted robot finishes expression animation display based on the plurality of image data packets. According to the method and the device, transmission accidents in the transmission process can be found in time, expression animations can be transmitted to the intelligent vehicle-mounted robot completely, and therefore the intelligent vehicle-mounted robot can achieve the estimation effect when the expression animations are displayed.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for transmitting an expression animation according to a second embodiment of the present invention.
Based on the first embodiment, the method for transmitting expression animation in this embodiment divides n frames of expression animation images into a plurality of image data packets, and transmits the plurality of image data packets by using an image data protocol, including:
step S401: dividing n frames of expression cartoon images into a plurality of image data packets.
It should be noted that n frames of animation images can be equally divided into a plurality of image data packets, and the size of each image data protocol is ensured to be the same as much as possible, so that the transmission time of each image data protocol is ensured to be consistent as much as possible, and it is prevented that whether a transmission accident occurs in the process of transmitting the image data protocols cannot be judged through the transmission time when the size difference of the image data protocols is too large.
Step S402: and generating a corresponding image data protocol according to the plurality of image data packets.
It should be noted that each image data packet has a corresponding image data protocol.
Specifically, the corresponding image data packet may be determined according to a packet sequence number in the image data protocol, and differences between different image data protocols mainly lie in differences between the packet sequence number and the image data.
Step S403: and transmitting the image data protocol in sequence based on the packet sequence number in the image data protocol.
It should be noted that when dividing the n frames of expression animation images into a plurality of image data packets, the n frames of expression animation images are divided according to the expression animation image sequence, for example, the 1 st to 5 th frames of expression animation images may be divided into the image data packet with the packet number 0, the 6 th to 10 th frames of expression animation images may be divided into the image data packet with the packet number 1, and so on, to complete the division of the n frames of expression animation images into a plurality of image data packets.
Step S404: and receiving a second data protocol of the intelligent vehicle-mounted robot.
In specific implementation, after the intelligent vehicle-mounted robot receives the image data protocol each time, the intelligent vehicle-mounted robot sends a second data protocol to the mobile phone APP terminal. When the intelligent vehicle-mounted robot receives the image data protocol and successfully verifies the image data protocol, sending a receiving completion protocol to the mobile phone APP terminal; and when the intelligent vehicle-mounted robot receives the image data protocol but fails in verification, sending a second error protocol to the mobile phone APP terminal.
Specifically, the format of the receiving end partial protocol is as follows: the protocol header, the protocol length, the protocol type, the image sequence number, the flag bit, the check bit and the protocol trailer, and the receiving partial protocol are as shown in the following table 5:
TABLE 5
The situation after the intelligent vehicle-mounted robot receives the image data protocol can be determined according to the flag bit in the received component protocol. For example, when the flag bit in the received component protocol is 0x00, it may be determined that the image data packet is successfully transmitted, when the flag bit in the received component protocol is 0x01, it may be determined that the image data packet is incomplete, that is, there is a problem that the image data packet received by the intelligent vehicle-mounted robot is incomplete due to partial data loss in the transmission process of the image data protocol, when the flag bit in the received component protocol is 0x02, it indicates that the intelligent vehicle-mounted robot has a failure in analyzing the image data packet, and when the flag bit in the received component protocol is 0x03, it indicates that the intelligent vehicle-mounted robot has a failure in analyzing the image after analyzing the image data packet.
In specific implementation, after receiving each image data protocol, the intelligent vehicle-mounted robot sends a received sub-protocol to the mobile phone APP terminal, and if the flag bit in the second data protocol is 0x01, it indicates that the image data protocol is successfully sent, and the image data packet received by the intelligent vehicle-mounted robot is complete, the intelligent vehicle-mounted robot successfully analyzes the image data packet, and the intelligent vehicle-mounted robot successfully analyzes the image data in the image data packet. After the image data protocol is successfully sent, the intelligent vehicle-mounted robot continues to send a request data protocol to continue to request the mobile phone APP terminal to send the next image data protocol until the intelligent vehicle-mounted robot receives all the image data protocols.
Step S405: and if the second data protocol is a second error protocol, determining a corresponding image data packet according to a packet sequence number in the second error protocol, and retransmitting the corresponding image data packet.
Specifically, the format of the second error protocol is: protocol header, protocol length, protocol type, error type, send flag, packet sequence number, check bit, and protocol trailer, the second error protocol is as shown in table 6 below:
TABLE 6
It should be noted that, when the sending flag in the second error protocol is 0x00, the mobile phone APP will stop sending the protocol, and when the sending flag in the second error protocol is 0x01, the mobile phone APP will resend the image data protocol corresponding to the packet number. The reason for the protocol check failure may also be determined according to the error type in the second error protocol, for example, when the error type in the second error protocol is 0x00, the reason for the check failure is a case that a protocol error occurs in the image data protocol, when the error type in the second error protocol is 0x01, the reason for the check failure is a check error that occurs in the checking process, when the error type in the second error protocol is 0x02, the reason for the check failure is a packet number error in the image data protocol (the image data protocol is transmitted in sequence according to packet numbers, and the packet number in the image data protocol received by the intelligent vehicle-mounted robot at the current time is the next sequence number of the packet number in the image data protocol received at the previous time), and when the error type in the second error protocol is 0x03, the reason for the check failure is another reason.
In specific implementation, when the sending flag in the second data protocol is received to be 0x01, the image data protocol corresponding to the packet serial number is sent again until the intelligent vehicle-mounted robot receives all the image data protocols and calculates the data positions according to the packet serial numbers to re-splice the expression animations.
In this embodiment, when dividing the n frames of expression animation images into a plurality of image data packets, the sizes of the image data packets are ensured to be consistent as much as possible, so that the transmission time of each image data protocol is ensured to be consistent, and whether a transmission accident occurs in the process of transmitting the image data protocol is timely discovered through the transmission time; the image data protocols are sent in sequence based on the packet serial numbers in the image data protocols, whether the currently transmitted image data protocols are wrong or not can be determined in time according to the packet serial numbers, the image data protocols are prevented from being transmitted more or less, and therefore the intelligent vehicle-mounted robot is ensured to receive all the image data protocols, and the expression animations can be transmitted to the intelligent vehicle-mounted robot completely; the image data protocol with transmission errors can be determined according to the packet sequence number in the second error protocol, the corresponding image data protocol can be rapidly determined according to the packet sequence number, and therefore the overall transmission time for transmitting the expression animation is effectively prolonged.
