Detailed Description
The invention will be described in further detail with reference to the accompanying drawings and specific examples.
A record replay system for a police plan making process comprises a man-machine interaction module, a log recording module, a playback driving module and a command interpretation module.
The man-machine interaction module receives user input and visually presents the plan to the user.
The log recording module records the operations in the user planning process in a specified format in a log file.
And the playback driving module sequentially takes out the operation instructions in the log according to the time sequence and gives the operation instructions to the command interpretation module for execution, so as to drive the multi-disc process to advance.
The command interpretation module executes the operation command and triggers the human-computer interface module to update the interface information display, thereby realizing playback of the planning process.
The operation instruction OP is divided into a view instruction and a data instruction. The view instruction refers to an instruction capable of causing a change in view without affecting the contents of the plan itself, and the data instruction refers to an instruction capable of causing a change in the contents of the plan itself.
The view instructions include three instructions of scale, roam, and rotate. The zoom instruction is in the form of scale (cof), c is a zoom factor, the standard size zoom factor of the view is 1, cof > 1 represents an enlarged view, and 0 < cof < 1 represents a reduced view; the roaming instruction is in the form of (raom, lon, lat), lon and lat represent coordinates of a display center point of the newly-placed electronic map; the rotation instruction is in the form of rotation, and deg is a rotation angle, and indicates that the electronic map deg is rotated clockwise by 0 degrees in the north direction.
The data instruction corresponds to the operation of the pre-proposal, the command interpretation module regards the pre-proposal as a tree structure and consists of a series of tree nodes, and the data instruction is divided into three instructions of adding (add), deleting (del) and updating (update) to the tree nodes. The adding instruction is in the form of (add,/root/. Degree/b/c, 'xx') which is the path of the newly added node in the tree structure, wherein val is the initial value corresponding to the newly added node, and if (add,/root/. Degree/b/c, 'xx') is the new child node c under the node b, the initial value is set as xx, and root is the root node of the tree structure; the delete instruction is in the form of (del, node) indicating deletion of node, e.g., (de, l/roo/t./b/c) indicating deletion of child node c of node b; the update instruction is in the form of update, node, newval, and indicates that the value of node is modified to newval.
As shown in fig. 1, the man-machine interface module displays different node mappings in the plan tree structure as different primitives in the view, and after the command interpretation module interprets the command, the man-machine interface module is invoked to display. The specific method comprises the following steps:
(1) Editing a plan: the user makes a plan, operates the plan through a man-machine interface, adjusts the view angle through a shortcut tool (zoom-in, zoom-out, roaming and rotation) provided by the interface, organizes the plan into a tree structure, and the plan elements correspond to nodes in a plan tree, and the new addition, modification and deletion of the plan elements correspond to the addition, update and deletion of the tree nodes. The man-machine interface module forwards the operation call to the command interpretation module in the planning process of the plan;
(2) Recording user operation behaviors through a log file: the command interpretation module interprets the operation call as an operation instruction OP in text form, interprets the adjustment of the view angle by the user as an angle instruction, and interprets the editing operation of the plan elements by the user as a data instruction. The zoom-in and zoom-out views are interpreted as scale instructions, the roaming is interpreted as a rom instruction, the rotation of the view is interpreted as a rotate instruction, the new operation of the plan elements is interpreted as add instructions, the modification operation of the plan elements is interpreted as update instructions, and the deletion of the plan elements is interpreted as del instructions. The command interpretation module transmits the operation command to the log recording module to record the operation command into the operation log, and the log recording module appends the operation command with the operation time to the end of the operation log file in the form of (time, OP) tuple, wherein the time represents the number of seconds from the beginning of planning the plan to the current passing time.
(3) Playback of user operation behavior by a timer-driven system: the user designates replay plans to carry out plan making process rewinding, the playback driving module initializes a timer, the second number increases from 0 to every second, and simultaneously reads an operation instruction with the operation time equal to the current second number in the log file and gives the operation instruction to the command interpretation module for processing;
(4) Interpreting the operation instruction and graphically displaying: the command interpretation module interprets the operation command, invokes the corresponding view angle operation on the view angle command to adjust the view angle, converts the data command into operation call modification plan tree node information, and simultaneously updates the human-computer interaction module to update the interface display.
(5) Ending playback: the playback driving module reads the end of the log file, and the plan making replay process is finished.
