Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Example 1
Fig. 1 shows a schematic frame diagram of a pan/tilt head control system in the present embodiment. As shown in fig. 1, the pan/tilt head control system includes a control center 11, a serial port converter 12 connected to the control center 11, a transmitting optical transceiver 13 and a local pan/tilt head 16 connected to the serial port converter 12, a receiving optical transceiver 14 connected to the transmitting optical transceiver 13 through an optical fiber, and a remote pan/tilt head 15 connected to the receiving optical transceiver 14. Specifically, the serial port converter 12 is a 232-to-422 serial port converter, and the control center 11 is connected to the 232-to-422 serial port converter through a 232 serial port line; the 232-to-422 serial port converter is connected with the transmitting optical terminal 13 and the local holder 16 through 422 serial port lines; the receiving optical transceiver 14 is connected with the far-end pan-tilt 15 through a 485 serial port line. The local cradle head 16 can perform bidirectional communication with the control center 11 through the serial port converter 12, and signals are communicated between the transmitting optical terminal 13 and the receiving optical terminal 14 in a unidirectional manner. In this embodiment, the serial port converter 12, the transmitting optical transceiver 13, and the local pan/tilt head 16 are disposed at positions close to the control center 11; the far-end cradle head 15 and the receiving optical transceiver 14 are arranged at a position far away from the control center 11, such as 10 km or more; the transmitting optical transceiver 13 and the receiving optical transceiver 14 are connected by an optical fiber.
As shown in fig. 2, the method for upgrading the pan/tilt head of the pan/tilt head control system includes the following steps:
s1: the control center 11 sends the current frame upgrading data to the sending optical transceiver 13 and the local cloud deck 16 through the serial port converter 12; the sending optical transceiver 13 sends the current frame upgrading data to the far-end pan-tilt 15 through the receiving optical transceiver 14. The control center 11 includes but is not limited to a PC, the PC uses a 232 serial port capable of sending an XMODEM protocol, the 232 serial port on the PC is connected to a 232-to-422 serial port converter through a 232 serial port line, the 232-to-422 serial port converter is connected to the sending optical transceiver 13 and the local pan/tilt head 16 through a 422 serial port line, and the receiving optical transceiver 14 is connected to the far-end pan/tilt head 15 through a 485 serial port line. In this embodiment, the serial parameter configurations of the local cradle head 16 and the remote cradle head 15 are the same, and the serial parameter configurations include a baud rate, a data bit, a stop bit, a parity bit, and the like, so as to ensure that the verification results of the local cradle head 16 and the remote cradle head 15 for verifying the received same current frame upgrade data are the same.
S2: the local pan/tilt head 16 receives the current frame upgrade data, checks the current frame upgrade data to generate a positive response signal or a negative response signal, and sends the positive response signal or the negative response signal to the control center 11 through the serial port converter 12. Because the control center 11 is connected with the local cloud deck 16 through the serial port converter 12, the local cloud deck 16 checks the received current frame upgrading data; if the verification is qualified, positive response information (namely ACK response) is returned to the control center 11 through the serial port converter 12; if the verification is not qualified, a negative response signal (i.e. NAK response) is returned to the control center 11 through the serial port converter 12.
In this embodiment, the control center 11 sends the current frame of upgrade data to the local pan-tilt 16 and the remote pan-tilt 15 having the same serial parameter configuration through the serial converter 12, and since the serial parameter configurations of the local pan-tilt 16 and the remote pan-tilt 15 are the same, when the local pan-tilt 16 and the remote pan-tilt 15 receive the same current frame of upgrade data, the verification results of the verification performed on the received same current frame of upgrade data by the local pan-tilt 16 and the remote pan-tilt 15 should be the same. That is, based on the same current frame of upgrade data, if the local cradle head 16 returns a positive response signal after verification, the far-end cradle head 15 returns a positive response signal to the receiving optical transceiver 14; if the local cradle head 16 returns a negative response signal after verification, the remote cradle head 15 returns a negative response signal to the receiving optical transceiver 14, but the positive response signal or the negative response signal returned by the remote cradle head 15 cannot be sent to the sending optical transceiver 13 through the receiving optical transceiver 14, so as to be sent to the control center 11. When the control center 11 cannot receive the positive response signal or the negative response signal sent by the remote pan/tilt head 15, the verification result of the remote pan/tilt head 15 verifying the received current frame upgrade data may be estimated based on the received positive response signal or the received negative response signal sent by the local pan/tilt head 16.
S3: the control center 11 receives the positive response signal or the negative response signal; when receiving the positive response signal, sending the next frame of upgrading data as the current frame of upgrading data; and repeatedly transmitting the current frame upgrading data when the negative response signal is received. Specifically, if the control center 11 receives a positive response signal returned by the local pan/tilt 16 through the serial port converter 12, the local pan/tilt 16 and the remote pan/tilt 15, which have the same presumed serial port parameter configuration, both receive the current frame of upgrade data and the current frame of upgrade data is verified to be qualified, so that the control center 11 sends the next frame of upgrade data as the current frame of upgrade data, and the step is repeated until all the upgrade data are sent to the local pan/tilt 16 and the remote pan/tilt 15. If the control center 11 receives a negative response signal returned by the local pan-tilt 16 through the serial port converter 12, it is estimated that both the local pan-tilt 16 and the remote pan-tilt 15 with the same serial port parameter configuration receive the current frame of upgrade data but the current frame of upgrade data is not qualified for verification, so that the control center 11 repeatedly sends the current frame of upgrade data to determine that both the local pan-tilt 16 and the remote pan-tilt 15 receive the current frame of upgrade data qualified for verification.
Further, after the control center 11 sends a plurality of current frame upgrade data to the local pan/tilt 16 and the remote pan/tilt 15 until all the upgrade data are sent, a text end signal (EOT signal) may be sent to the local pan/tilt 16 and the remote pan/tilt 15 to remind that all the upgrade data of the local pan/tilt 16 and the remote pan/tilt 15 have been sent, so that the local pan/tilt 16 and the remote pan/tilt 15 may be upgraded based on all the received current frame upgrade data; after receiving the end of text signal (EOT signal), the local cradle head 16 may send an affirmative response signal (ACK response) to the control center 11 through the serial port converter 12 to notify the control center 11 that the end of text signal (EOT signal) has been received, thereby determining that the local cradle head 16 has received all the upgrade data, and presuming that the remote cradle head 15 has received all the upgrade data.
S4: the far-end pan-tilt 15 receives the current frame upgrading data, and completes the upgrading of the far-end pan-tilt 15 based on all the current frame upgrading data. Specifically, the remote pan/tilt 15 receives all current frame upgrade data continuously sent by the control center 11, runs a Bootloader program on the remote pan/tilt 15, and executes all the received current frame upgrade data to complete the upgrade of the remote pan/tilt 15. In the method for upgrading the pan/tilt head of the pan/tilt head control system provided in this embodiment, the local pan/tilt head 16 and the remote pan/tilt head 15 may receive the same current frame upgrading data when the serial port converter 12, the transmitting optical transmitter/receiver 13, the receiving optical transmitter/receiver 14, the local pan/tilt head 16, and the remote pan/tilt head 15 are intact. Under the condition that the hardware and Bootloader program of the remote platform are intact, if the remote pan-tilt 15 receives all the current frame upgrading data which is from the control center 11 and checked to be correct, the upgrading can be successful.
S5: the local pan/tilt 16 receives the current frame update data, and completes the update of the local pan/tilt 16 based on all the current frame update data. Specifically, the local pan/tilt 16 receives all current frame upgrade data continuously sent by the control center 11, runs a Bootloader program on the local pan/tilt 16, and executes all the received current frame upgrade data to complete the upgrade of the local pan/tilt 16. In this embodiment, under the condition that the hardware of the local pan/tilt head 16 and the Bootloader program are intact, if the local pan/tilt head 16 receives all the current frame update data from the control center 11 without error check, the update may be successful.
Specifically, the far-end pan-tilt 15 receives the current frame of upgrade data and completes the upgrade in the 485 serial port communication mode. In this embodiment, the far-end pan-tilt 15 is in communication connection with the receiving optical transceiver 14 through a 485 serial port line, so that the far-end pan-tilt 15 receives the current frame upgrade data in the 485 serial port communication mode, and the far-end pan-tilt 15 completes the upgrade based on all the received current frame upgrade data in the 485 serial port communication mode. The remote cradle head 15 is upgraded in the 485 serial communication mode, and maintenance personnel can continue upgrading in the 485 serial communication mode on site under the condition that the local cradle head 16 assists in upgrading failure. Further, the local pan/tilt head 16 receives the current frame upgrade data and completes the upgrade in the 422 serial port communication mode, so as to ensure that the transmission of the current frame upgrade data is not interfered.
In order to ensure that the local pan-tilt 16 and the far-end pan-tilt 15 can receive the same current frame of updating data, the local pan-tilt 16 and the far-end pan-tilt 15 are in a receiving state at the same time when the control center 11 needs to send the current frame of updating data. It can be understood that, if the local pan/tilt head 16 and the remote pan/tilt head 15 are not in the receiving state at the same time, the local pan/tilt head 16 and the remote pan/tilt head 15 may receive different current frame upgrading data, and based on the different current frame upgrading data, the verification results of the local pan/tilt head 16 and the remote pan/tilt head 15 are different, so that the control center 11 cannot determine whether the remote platform receives the current frame upgrading data without error.
As shown in fig. 1, the control center 11 uses a 232 serial port for sending the XMODEM protocol and is connected to the 232-to-422 serial port converter through a 232 serial port line, and the control center 11 can send the current frame upgrade data to the 232-to-422 serial port converter. After the 232-to-422 serial port converter receives the current frame of upgrade data, the current frame of upgrade data is transmitted to the transmitting optical transceiver 13 and the local pan/tilt 16, which are provided with the receiving end RX, through the transmitting end TX. The transmitting optical transceiver 13 transmits the received current frame upgrade data to the receiving optical transceiver 14 through an optical fiber, and the receiving optical transceiver 14 transmits the current frame upgrade data to a far-end pan-tilt 15 provided with a receiving end RX through a transmitting end TX. The local pan/tilt 16 checks the current frame of the upgrade data after receiving the current frame of the upgrade data, and sends a positive response signal or a negative response signal to the receiving end RX of the 232-to-422 serial converter through the transmitting end TX of the local pan/tilt 16, and the 232-to-422 serial converter sends the positive response signal or the negative response signal to the control center 11. After receiving the positive response signal or the negative response signal, the control center 11 determines whether to send the next frame of upgrade data as the current frame of upgrade data or to repeatedly send the current frame of upgrade data, and then directly sends all the upgrade data again. The local pan-tilt 16 and the remote pan-tilt 15 complete the equipment upgrade based on all the received current frame upgrade data.
In the method for upgrading the pan/tilt head of the pan/tilt head control system provided in this embodiment, the local pan/tilt head 16 capable of bidirectionally communicating with the serial port converter 12 is added to the existing pan/tilt head control system, so that the control center 11 sends the current frame upgrade data to the local pan/tilt head 16 and the remote pan/tilt head 15, and the current frame upgrade data is verified by the local pan/tilt head 16, so that the remote pan/tilt head 15 can receive all the current frame upgrade data without error, thereby completing the upgrade of the remote pan/tilt head 15. In the cloud platform upgrading method of the cloud platform control system, the remote cloud platform 15 is upgraded by the aid of the local cloud platform 16, the remote cloud platform 15 is intelligently upgraded, and a maintainer does not need to upgrade and maintain on site in the process, so that labor cost and time cost are saved.
Example 2
Fig. 1 shows a schematic frame diagram of a pan/tilt head control system in the present embodiment. As shown in fig. 1, the pan/tilt head control system includes a control center 11, a serial port converter 12 connected to the control center 11, a transmitting optical transceiver 13 and a local pan/tilt head 16 connected to the serial port converter 12, a receiving optical transceiver 14 connected to the transmitting optical transceiver 13 through an optical fiber, and a remote pan/tilt head 15 connected to the receiving optical transceiver 14. Specifically, the serial port converter 12 is a 232-to-422 serial port converter, and the control center 11 is connected to the 232-to-422 serial port converter through a 232 serial port line; the 232-to-422 serial port converter is connected with the transmitting optical terminal 13 and the local holder 16 through 422 serial port lines; the receiving optical transceiver 14 is connected with the far-end pan-tilt 15 through a 485 serial port line. The local cradle head 16 can perform bidirectional communication with the control center 11 through the serial port converter 12, and signals are communicated between the transmitting optical terminal 13 and the receiving optical terminal 14 in a unidirectional manner. In this embodiment, the serial port converter 12, the transmitting optical transceiver 13, and the local pan/tilt head 16 are disposed at positions close to the control center 11; the far-end cradle head 15 and the receiving optical transceiver 14 are arranged at a position far away from the control center 11, such as 10 km or more; the transmitting optical transceiver 13 and the receiving optical transceiver 14 are connected by an optical fiber.
The control center 11 is configured to send the current frame upgrade data to the sending optical transceiver 13 and the local pan/tilt 16 through the serial port converter 12; the sending optical transceiver 13 sends the current frame upgrading data to the far-end pan-tilt 15 through the receiving optical transceiver 14. The control center 11 includes but is not limited to a PC, the PC uses a 232 serial port capable of sending an XMODEM protocol, the 232 serial port on the PC is connected to a 232-to-422 serial port converter through a 232 serial port line, the 232-to-422 serial port converter is connected to the sending optical transceiver 13 and the local pan/tilt head 16 through a 422 serial port line, and the receiving optical transceiver 14 is connected to the far-end pan/tilt head 15 through a 485 serial port line. In this embodiment, the serial parameter configurations of the local cradle head 16 and the remote cradle head 15 are the same, and the serial parameter configurations include a baud rate, a data bit, a stop bit, a parity bit, and the like, so as to ensure that the verification results of the local cradle head 16 and the remote cradle head 15 for verifying the received same current frame upgrade data are the same.
And the local cloud deck 16 is configured to receive the current frame upgrade data, check the current frame upgrade data to generate a positive response signal or a negative response signal, and send the positive response signal or the negative response signal to the control center 11 through the serial port converter 12. Because the control center 11 is connected with the local cloud deck 16 through the serial port converter 12, the local cloud deck 16 checks the received current frame upgrading data; if the verification is qualified, positive response information (namely ACK response) is returned to the control center 11 through the serial port converter 12; if the verification is not qualified, a negative response signal (i.e. NAK response) is returned to the control center 11 through the serial port converter 12.
In this embodiment, the control center 11 sends the current frame of upgrade data to the local pan-tilt 16 and the remote pan-tilt 15 having the same serial parameter configuration through the serial converter 12, and since the serial parameter configurations of the local pan-tilt 16 and the remote pan-tilt 15 are the same, when the local pan-tilt 16 and the remote pan-tilt 15 receive the same current frame of upgrade data, the verification results of the verification performed on the received same current frame of upgrade data by the local pan-tilt 16 and the remote pan-tilt 15 should be the same. That is, based on the same current frame of upgrade data, if the local cradle head 16 returns a positive response signal after verification, the far-end cradle head 15 returns a positive response signal to the receiving optical transceiver 14; if the local cradle head 16 returns a negative response signal after verification, the remote cradle head 15 returns a negative response signal to the receiving optical transceiver 14, but the positive response signal or the negative response signal returned by the remote cradle head 15 cannot be sent to the sending optical transceiver 13 through the receiving optical transceiver 14, so as to be sent to the control center 11. When the control center 11 cannot receive the positive response signal or the negative response signal sent by the remote pan/tilt head 15, the verification result of the remote pan/tilt head 15 verifying the received current frame upgrade data may be estimated based on the received positive response signal or the received negative response signal sent by the local pan/tilt head 16.
A control center 11 for receiving a positive response signal or a negative response signal; when receiving the positive response signal, sending the next frame of upgrading data as the current frame of upgrading data; and repeatedly transmitting the current frame upgrading data when the negative response signal is received. Specifically, if the control center 11 receives a positive response signal returned by the local pan/tilt 16 through the serial port converter 12, the local pan/tilt 16 and the remote pan/tilt 15, which have the same presumed serial port parameter configuration, both receive the current frame of upgrade data and the current frame of upgrade data is verified to be qualified, so that the control center 11 sends the next frame of upgrade data as the current frame of upgrade data, and the step is repeated until all the upgrade data are sent to the local pan/tilt 16 and the remote pan/tilt 15. If the control center 11 receives a negative response signal returned by the local pan-tilt 16 through the serial port converter 12, it is estimated that both the local pan-tilt 16 and the remote pan-tilt 15 with the same serial port parameter configuration receive the current frame of upgrade data but the current frame of upgrade data is not qualified for verification, so that the control center 11 repeatedly sends the current frame of upgrade data to determine that both the local pan-tilt 16 and the remote pan-tilt 15 receive the current frame of upgrade data qualified for verification.
Further, after the control center 11 sends a plurality of current frame upgrade data to the local pan/tilt 16 and the remote pan/tilt 15 until all the upgrade data are sent, a text end signal (EOT signal) may be sent to the local pan/tilt 16 and the remote pan/tilt 15 to remind that all the upgrade data of the local pan/tilt 16 and the remote pan/tilt 15 have been sent, so that the local pan/tilt 16 and the remote pan/tilt 15 may be upgraded based on all the received current frame upgrade data; after receiving the end of text signal (EOT signal), the local cradle head 16 may send an affirmative response signal (ACK response) to the control center 11 through the serial port converter 12 to notify the control center 11 that the end of text signal (EOT signal) has been received, thereby determining that the local cradle head 16 has received all the upgrade data, and presuming that the remote cradle head 15 has received all the upgrade data.
And the far-end cloud platform 15 is used for receiving the current frame upgrading data and finishing the upgrading of the far-end cloud platform 15 based on all the current frame upgrading data. Specifically, the remote pan/tilt 15 receives all current frame upgrade data continuously sent by the control center 11, runs a Bootloader program on the remote pan/tilt 15, and executes all the received current frame upgrade data to complete the upgrade of the remote pan/tilt 15. In the pan/tilt head upgrading device of the pan/tilt head control system provided in this embodiment, under the condition that the serial port converter 12, the transmitting optical transceiver 13, the receiving optical transceiver 14, the local pan/tilt head 16, and the remote pan/tilt head 15 are intact, the local pan/tilt head 16 and the remote pan/tilt head 15 may receive the same current frame upgrading data. Under the condition that the hardware and Bootloader program of the remote platform are intact, if the remote pan-tilt 15 receives all the current frame upgrading data which is from the control center 11 and checked to be correct, the upgrading can be successful.
And the local cloud platform 16 is used for receiving the current frame upgrading data and finishing the upgrading of the local cloud platform 16 based on all the current frame upgrading data. Specifically, the local pan/tilt 16 receives all current frame upgrade data continuously sent by the control center 11, runs a Bootloader program on the local pan/tilt 16, and executes all the received current frame upgrade data to complete the upgrade of the local pan/tilt 16. In this embodiment, under the condition that the hardware of the local pan/tilt head 16 and the Bootloader program are intact, if the local pan/tilt head 16 receives all the current frame update data from the control center 11 without error check, the update may be successful.
Specifically, the far-end pan-tilt 15 receives the current frame of upgrade data and completes the upgrade in the 485 serial port communication mode. In this embodiment, the far-end pan-tilt 15 is in communication connection with the receiving optical transceiver 14 through a 485 serial port line, so that the far-end pan-tilt 15 receives the current frame upgrade data in the 485 serial port communication mode, and the far-end pan-tilt 15 completes the upgrade based on all the received current frame upgrade data in the 485 serial port communication mode. The remote cradle head 15 is upgraded in the 485 serial communication mode, and maintenance personnel can continue upgrading in the 485 serial communication mode on site under the condition that the local cradle head 16 assists in upgrading failure. Further, the local pan/tilt head 16 receives the current frame upgrade data and completes the upgrade in the 422 serial port communication mode, so as to ensure that the transmission of the current frame upgrade data is not interfered.
In order to ensure that the local pan-tilt 16 and the far-end pan-tilt 15 can receive the same current frame of updating data, the local pan-tilt 16 and the far-end pan-tilt 15 are in a receiving state at the same time when the control center 11 needs to send the current frame of updating data. It can be understood that, if the local pan/tilt head 16 and the remote pan/tilt head 15 are not in the receiving state at the same time, the local pan/tilt head 16 and the remote pan/tilt head 15 may receive different current frame upgrading data, and based on the different current frame upgrading data, the verification results of the local pan/tilt head 16 and the remote pan/tilt head 15 are different, so that the control center 11 cannot determine whether the remote platform receives the current frame upgrading data without error.
As shown in fig. 1, the control center 11 uses a 232 serial port for sending the XMODEM protocol and is connected to the 232-to-422 serial port converter through a 232 serial port line, and the control center 11 can send the current frame upgrade data to the 232-to-422 serial port converter. After the 232-to-422 serial port converter receives the current frame of upgrade data, the current frame of upgrade data is transmitted to the transmitting optical transceiver 13 and the local pan/tilt 16, which are provided with the receiving end RX, through the transmitting end TX. The transmitting optical transceiver 13 transmits the received current frame upgrade data to the receiving optical transceiver 14 through an optical fiber, and the receiving optical transceiver 14 transmits the current frame upgrade data to a far-end pan-tilt 15 provided with a receiving end RX through a transmitting end TX. The local pan/tilt 16 checks the current frame of the upgrade data after receiving the current frame of the upgrade data, and sends a positive response signal or a negative response signal to the receiving end RX of the 232-to-422 serial converter through the transmitting end TX of the local pan/tilt 16, and the 232-to-422 serial converter sends the positive response signal or the negative response signal to the control center 11. After receiving the positive response signal or the negative response signal, the control center 11 determines whether to send the next frame of upgrade data as the current frame of upgrade data or to repeatedly send the current frame of upgrade data, and then directly sends all the upgrade data again. The local pan-tilt 16 and the remote pan-tilt 15 complete the equipment upgrade based on all the received current frame upgrade data.
In the pan-tilt control system provided in this embodiment, the local pan-tilt 16 capable of bidirectionally communicating with the serial port converter 12 is added to the existing pan-tilt control system, so that the control center 11 sends the current frame upgrade data to the local pan-tilt 16 and the remote pan-tilt 15, and the remote pan-tilt 15 can receive all the current frame upgrade data without error through the verification of the local pan-tilt 16 on the current frame upgrade data, so as to complete the upgrade of the remote pan-tilt 15. In the holder control system, the remote holder 15 is upgraded by the aid of the local holder 16, the remote holder 15 is intelligently upgraded, and a maintainer does not need to upgrade and maintain on site in the process, so that labor cost and time cost are saved.
