Also, like reference numerals are used to refer to like parts throughout the drawings. In the drawings:

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention, but do not limit the invention to only some, but not all embodiments.
The inventor finds that, in the current weather bureau, a multi-host and multi-display system generally adopts a large-scale matrix type architecture, and is integrated and controlled by one KVM switch, and the KVM console connected by a wire is used for realizing the KVM control of the whole weather bureau system.
However, this control method can only be wired to the KVM switch through the KVM console, i.e. the user cannot implement KVM switch control anywhere, which must be implemented on the KVM switch, which is inconvenient. For example: the displayer corresponding to a certain seat end displays a thunderstorm weather meteorological chart, when the seat end needs to control the displayer to display an actual video chart of a thunderstorm area, a user needs to perform switching operation by himself or by informing a specially-assigned person to go to a KVM switcher, the displayer can display the required actual video chart, the control mode is inconvenient, and the working efficiency of the user is reduced.
In addition, if a problem occurs in the KVM switch or a problem occurs in a certain path of resource data, the KVM cannot realize the switching control.
Based on the above problems, the inventor has diligently studied, tested and creatively proposed the wireless KVM control system of the present invention to solve the above problems.
Referring to FIG. 1, a schematic diagram of a wireless KVM control system according to an embodiment of the present invention is shown, the system comprising: the system comprises distributed input nodes, distributed output nodes, a switch, a wireless router, a main server, a mobile terminal and a plurality of display devices; the main server is connected with the switch through the distributed input nodes, the main server is used for providing multi-channel resource data, each channel of resource data is transmitted to the switch through one distributed input node, and each channel of resource data represents one resource data required for analyzing weather phenomena. It should be noted that, in the embodiment of the present invention, the main server is a server that can receive all resource data required for analyzing weather phenomena, the types of the resource data may be one type or multiple types, and the host (or the server) that stores each type of resource data can send its own resource data to the main server, so that all resource data can be summarized, and managed by the main server, the transmission efficiency of the whole resource data can be improved, and the use by a user is facilitated. Of course, the host of each resource may send its own resource data to the switch through the distributed input nodes without using the master server.
In the embodiment of the invention, the switch is connected with the plurality of display devices through the distributed output nodes and is used for transmitting the multi-path resource data to the plurality of display devices in a network mode, so that the plurality of display devices display the corresponding resource data, and each path of resource data is transmitted to one display device through one distributed output node. In the current weather bureau, because a KVM switch is used, the transmission of the resource data is generally performed in a manner of a video cable (for example, DVI, HDMI, etc.), but in the present application, because the KVM switch is not used, a switch is used, so the resource data is transmitted between the switch and the distributed input nodes and between the switch and the distributed output nodes through a network, and in order to ensure the efficiency and quality of the resource data transmission, a preferred choice is to use a gigabit switch and at least two six types of network cables, wherein one of the six types of network cables is used for the resource data transmission between the switch and the distributed input nodes, and the other six types of network cables are used for the resource data transmission between the switch and the distributed output nodes. Of course, there are several distributed input nodes connected to the switch, and there are several six types of network cables, and similarly, there are several distributed output nodes connected to the switch, and there are several six types of network cables. For example: the number of the distributed input nodes is 6, the number of the distributed output nodes is 6, then a six-type network cable is connected between each distributed input node and the switch, the number of the six-type network cables is 6, a six-type network cable is also connected between each distributed output node and the switch, the number of the six-type network cables is 6, and the whole switch is required to be connected with 12 six-type network cables.
In the embodiment of the invention, the wireless router is respectively connected with the switch and the mobile terminal and is used for realizing data interaction between the mobile terminal and the switch in a wireless mode, and the data in the wireless mode comprises: a control instruction issued by the mobile terminal; the main server is connected with each distributed input node through a USB line and a data line, and the corresponding resource data is transmitted between each distributed input node and the switch, and meanwhile, the control instruction sent by the mobile terminal through the switch is transmitted through the USB line. Since the present application does not use a wired KVM console and KVM switch, but instead uses a mobile terminal and a switch, the mobile terminal needs to be able to perform data interaction with the switch. A wireless router is added in the whole system, and the mobile terminal performs data interaction with the switch through the wireless router.
In the embodiment of the invention, the wireless router and the switch can be in a wireless connection mode or a wired connection mode, but the wireless router and the mobile terminal need to be in a wireless connection mode, so that the mobile terminal can obtain resource data and issue a control instruction at any position. Of course, it can be understood that the wireless router has a wireless signal coverage, if the wireless router exceeds the signal coverage, an intermediate wireless base station or the like is required to expand the wireless signal coverage, otherwise, the mobile terminal cannot obtain the resource data and issue the control command.
In the embodiment of the invention, a main server transmits multi-channel resource data to a distributed input node through a data line (or a video line); six types of network cables are multiplexed between the distributed input nodes and the switch to transmit control commands and multi-channel resource data. In order to realize the control of the mobile terminal on the resource data, a KVM control program is arranged in both the main server and the mobile terminal, and the mobile terminal issues a control instruction to the main server through the KVM control program so as to realize the wireless KVM control of the mobile terminal on the display of the plurality of display devices for displaying the respective corresponding resource data.
Specifically, the mobile terminal obtains the multi-channel resource data from the switch and displays the multi-channel resource data on a screen of the mobile terminal, and certainly, data interaction between the mobile terminal and the switch is realized by a wireless router. The user can see the resource data on the screen of the mobile terminal, and since the mobile terminal can receive all the resource data, the user can switch to display different resource data through the KVM control program on the mobile terminal, and at the same time, the user can also control the resource data by using the KVM control program, for example: the data of a certain weather map is modified, the position of a certain geographic image is marked, and the like, so that a user can directly perform touch operation on the mobile terminal, and the control on the resource data can be simply and quickly realized.
After receiving the touch operation of a user, the mobile terminal generates a corresponding control instruction according to the touch operation and issues the control instruction to the distributed input nodes through the wireless router and the switch, wherein the control instruction comprises: the number of the at least one distributed input node is multiple, so that the control of which resource data needs to be sent to the distributed input node transmitting the resource data, and the number of the distributed input node needs to be sent in the control instruction issued by the mobile terminal.
After receiving the control instruction, the distributed input node sends the control instruction to the main server, and the control instruction can be essentially understood to be equivalent to the operation of a keyboard and a mouse, so the control instruction needs to be transmitted to the main server through a USB (universal serial bus) line. The main server receives and analyzes the control instruction through the KVM control program to obtain a correct control instruction, then executes corresponding control operation according to the analyzed control instruction, and finally sends the resource data subjected to the control operation to the corresponding distributed input nodes to be transmitted to the switch and the mobile terminal through the distributed input nodes.
In the embodiment of the present invention, in order to expand the control function of the entire system, both the distributed input node and the distributed output node are provided with: 232 control interface, 485 control interface, infrared control interface, and other controllable interfaces that may be used to connect external control devices, such as: the 232 control interface can be externally connected with serial communication equipment, and the infrared control interface can be externally connected with infrared detection equipment and the like.
In the embodiment of the invention, the distributed output node can be equal to the current seat end, and in consideration of some complex operations, the operation on the mobile terminal is possibly not convenient in a keyboard and mouse mode, so that the distributed output node is also provided with: the distributed output nodes can be externally connected with a keyboard and a mouse through the USB interface, so that a user can complete the operation through the keyboard and the mouse on the distributed output nodes when needing to perform complex operations, and the working efficiency of the user is further improved.
In the embodiment of the invention, after receiving the function operation performed by a user through a keyboard and a mouse, the distributed output node generates a corresponding seat end instruction according to the function operation, issues the seat end instruction to the switch through multiplexing six types of network cables, and then issues the seat end instruction to the distributed input node through the switch, and after receiving the seat end instruction, the distributed input node also needs to send the seat end instruction to the main server through a USB cable. And after receiving and analyzing the seat end instruction, the main server executes corresponding functional operation according to the analyzed seat end instruction. And finally, the main server sends the resource data subjected to the function operation to the corresponding distributed input nodes, so that the resource data are transmitted to the switch and the mobile terminal through the distributed input nodes and then transmitted to a plurality of display devices through the distributed output nodes for display, and the modified resource data can be displayed on the mobile terminal and the display devices.
In the embodiment of the present invention, in order to meet the actual working requirement, the distributed output node includes: a permission level; the whole system also comprises: and the leader terminal has the highest authority level. Because the distributed terminal output nodes are equal to the agent terminals, the authority levels need to be divided according to the working properties of the distributed output nodes, the distributed output nodes have different access authorities and control authorities according to the authority levels, and the distributed output nodes with higher levels have the authority of the distributed output nodes with lower access and control levels. For example: the distributed output nodes with the higher user operation permission level can access and control the distributed output nodes with the lower user operation permission level, and naturally, the distributed output nodes with the lower user operation permission level cannot access and control the distributed output nodes with the higher user operation permission level, and the distributed output node with the lowest user operation permission level cannot issue a control instruction to the main server. For example: in actual work, some new interns cannot arrange to operate some important resource data, and need to learn from the basis, so that the interns can operate distributed output nodes with lower or lowest authority levels, and even if the interns fail to operate, the operation of the whole system and the analysis of weather and weather are not influenced basically. These problems can be avoided well by the restriction of the permission level. If the intern needs to perform resource data control, the intern needs to send a control instruction to be issued to the mobile terminal first, or to the superior management terminal, or to the leader terminal, so as to allow other non-interns to check the control instruction, ensure the control instruction to be correct, and not affect the normal work of the whole system and the analysis of weather and weather.
Therefore, in the embodiment of the present invention, the following are set: the distributed output node with the lowest authority level cannot directly issue a control instruction to the main server; the distributed output node with the lowest authority level sends a control instruction required to be issued to the mobile terminal, or sends the control instruction to a superior management terminal, or can also send the control instruction to the leader terminal; and the mobile terminal receives and audits the control instruction to be issued, and under the condition that the audit is passed, the mobile terminal sends the control instruction to be issued by the distributed output node with the lowest authority level to the main server, and the main server performs control operation on the resource data according to the control instruction according to the same method.
If the control command is generated by the leader terminal, the control command can be directly issued to the main server and does not need to be sent to the mobile terminal or the superior management terminal, because the control command does not need to be checked.
In the embodiment of the invention, a special condition is provided, when an emergency alarm event occurs, so that all users can know the emergency alarm event in time to analyze, deal with and process in time. Therefore, when an emergency alarm event occurs, the distributed output node of any authority level pushes the resource data corresponding to the emergency alarm event to the other distributed output nodes so that the resource data corresponding to the emergency alarm event can be respectively displayed by the display devices connected with the other distributed output nodes, or when the emergency alarm event occurs, the distributed output node of any authority level pushes the resource data corresponding to the emergency alarm event to the leader terminal so that the resource data corresponding to the emergency alarm event can be displayed by the leader terminal. Therefore, all users can know the emergency alarm event in time, and then analyze, deal with and process the emergency alarm event in time.

The 9 output nodes are also connected with 9 display screens (display screen 1, display screen 2 …, display screen 9 in fig. 2) through 9 video lines. It should be noted that, fig. 2 exemplarily shows 9 display screens, which may also be a large display screen that simultaneously displays 9 video frames, that is, the 9 video frames are spliced on the large display screen, and this function may also be implemented by a user operating a KVM control program of a tablet computer.
