The front-end device control method of the present application is further described below with reference to fig. 3 to 5.
The http front-end device control request 21 sent by the traffic police terminal is sent to the request parser 23 through the http gateway, and the request parser 23 parses the terminal identifier, the target device identifier, and the first format operation instruction 30. The first format operation instruction 30 may include a rotation operation, a lens control operation, a termination operation, a preset bit operation, a lock operation, and the like, according to the type of the control request. Taking the http front-end device control request 21 sent by the traffic police terminal as an example, the following contents are provided:
after the analysis, the expression "100.51.175.12: 7000" represents the IP address and port of the traffic police terminal in the terminal identifier, and the descriptions of other various parameters are shown in table 1:
where "type = ptz" indicates that the first format operation instruction 30 carried by the http front-end device control request 21 is a rotation operation instruction, "direct = u" indicates that the operation sub-command corresponding to the rotation operation instruction is an upward rotation, and "speed = 120" indicates that the speed of the upward rotation is 120 degrees per second. When the first format operation instruction 30 is a lens control operation instruction, the corresponding command type and assignment are aperture control "type = aperture", magnification control "type = zoom", or focus control "type = focus", respectively. When the first format operation instruction 30 is a termination operation instruction, the corresponding command type and assignment are termination rotation "type = stopPtz", termination focus "type = stopFocus", termination iris control "type = stoptask", termination zoom control "type = stopZoom", and the like, respectively. When the first format operation instruction 30 is a preset bit operation instruction, the corresponding command type and assignment are a set preset bit "type = preset", a call preset bit "type = presetCall", a delete preset bit "type = presetDelete", or the like, respectively. When the first format operation instruction 30 is a lock operation instruction, the corresponding command type and assignment may be any one of the command types and assignments described above, and corresponding lock control is performed through an operation sub-command following the operation command.
After the first format operation instruction 30 is obtained through analysis, the operation instruction generator 24 obtains a second format operation instruction 40 corresponding to the first format operation instruction 30 according to the first format operation instruction 30 and a preset format conversion table, where the first format operation instruction 30 is an english operation instruction, and the second format operation instruction 40 is a 16-system hardware operation instruction. In one embodiment, the steps specifically include: an operation terminal 41 for generating a second format operation instruction 40 according to the operation command 31 corresponding to the first format operation instruction 30; generating an operation code of the second format operation instruction 40 according to the operation sub-command corresponding to the operation command 31; generating a check bit 43 of the second format operation instruction 40 according to the operation terminal 41 and the operation code; the operation terminal 41, the operation code and the check bit 43 are combined to generate the second format operation instruction 40.
The assignment value of the operation command 31 is ptz, and the operation command is converted into the operation header 41 of the second format operation instruction 40 according to a preset format conversion table, which is used as the 1 st bit of the second format operation instruction 40, and the specific numerical value is 0xA 5.
The operation command 31 corresponds to a plurality of operation subcommands, and the number and type of the operation subcommands are different according to the different complexity of the request content, so that the more complicated the request content is, the more the number and type of the corresponding operation subcommands are, and the more accurate the control of the front-end device is. Each operation subcommand corresponds to a one-bit opcode that translates into a second format operation instruction 40.
In one embodiment, the step of generating the operation code comprises: classifying the plurality of operation subcommands corresponding to the operation command 31, determining the positions of the operation codes corresponding to the various operation subcommands in the second format operation instruction 40 according to a preset sequence, and sequentially generating the operation code corresponding to each operation subcommand. As shown in fig. 4, taking four types of operation subcommands as an example, the various types of operation subcommands are sorted in the front-back order in the http front-end device control request 21, and sequentially include a first operation subcommand 321, a second operation subcommand 322, a third operation subcommand 323, and a fourth operation subcommand 324. The first operation sub-command 321 is used to define the rotation direction of the target device, and is correspondingly converted into the first operation code 421, and is located at the 2 nd bit of the second format operation instruction 40, and the value of the 16 th digit of the first operation code 421 is different according to the rotation direction. The second operation subcommand 322 is used to define the vertical speed and the horizontal speed of the target device, and is correspondingly converted into the second operation code 422, which is located at the 3 rd bit of the second format operation instruction 40. And in turn, the third operation subcommand 323 is converted into the third operation code 423 located at the 4 th bit of the second format operation instruction 40, the fourth operation subcommand 324 is converted into the fourth operation code 424 located at the 5 th bit of the second format operation instruction 40, until all the operation subcommands corresponding to the operation command 31 are converted. Then, a check bit 43 is added after the operation terminal 41 and the operation code, and the calculation formula of the check bit is as follows: (upper 4 bits of byte 1 + lower 4 bits of byte 1 + upper 4 bits of byte 2)% 16, where byte 1 is the 1 st bit of the second format operation instruction 40 and byte 2 is the 2 nd bit of the second format operation instruction 40. And combining the operation terminal 41, the operation code and the check bit to generate a second format operation instruction 40.
In an embodiment, the step of generating the second format operation instruction 40 includes: after the first format operation instruction 30 is obtained, a preset format conversion table is searched to obtain an operation wharf 41 corresponding to the operation command 31 of the first format operation instruction 30 and an operation code corresponding to the operation subcommand, a check bit 43 corresponding to the first format operation instruction 30 is obtained through calculation, and a second format operation instruction 40 is generated according to the search result and the calculation result. For the operation command 31 and each operation sub-command of the first format operation command 30, a unique operation terminal or operation code is corresponding to the operation command in a preset format conversion table, the format conversion table can be stored in a data server in advance, after the first format operation command 30 is analyzed and enters the operation command generator 24, the operation command generator 24 performs corresponding search from the format conversion table, then performs format conversion, and then calculates to obtain a corresponding check bit to detect whether the data is in error in the conversion process, and finally generates the second format operation command 40 according to the search result and the calculation result.
After generating the second format operating instructions 40, the sip request generator 25 generates the sip front-end device control request 80 based on the target device identification and the second format operating instructions 40. In one embodiment, the steps specifically include: generating a sip request header 60 according to the target device identifier; generating a sip message body 70 according to the second format operation instruction 40; the sip request header 60 and sip message body 70 are combined to generate the sip frontend device control request 80. The data server includes a front-end device storage unit in which access addresses of a plurality of front-end devices registered in the intelligent transportation system and other related information are stored, and the sip request generator 25 acquires a target device access address 50 from the front-end device address storage unit based on a target device identification, and then generates a sip request header 60 based on the address. Then, the second format operation instruction 40 is processed to generate an sip message body 70, and finally, the sip request header 60 and the sip message body 70 are combined to generate an sip front-end device control request 80.
After the sip frontend device control request 80 is generated, the sip frontend device control request is sent to the sip gateway 26, then the target device access address 50 is obtained from the frontend device address storage unit according to the target device identification, and the sip frontend device control request 80 is sent to the target device 27 based on the sip protocol. The target device 27, upon receiving the request, determines whether the front-end pan/tilt head or the front-end camera performs a corresponding control operation according to the specific content of the request. When the request relates to the adjustment of the focal length of the lens and the enlargement and reduction of the picture, the front-end camera executes corresponding operation, and when the request relates to the adjustment of rotation, preset positions and the like, the front-end holder executes corresponding operation. The traffic police terminal sends different types of control requests, so that the front-end equipment executes different control operations, multi-azimuth video data can be acquired, the accuracy of illegal data identification is improved, and the video acquisition requirements under different scenes are met.
In the above embodiment, the http front-end device control request 21 sent by the traffic police terminal is a no-response request, that is, after the request is sent to the target device 27, the target device 27 directly responds and executes the corresponding control operation, without returning a control response to the traffic police terminal.
