Description

Technical Field

[0001] This invention relates to the field of external devices for automatic recovery of communication disconnection, and particularly to an external device for automatic recovery of communication disconnection based on state layering and its usage method. Background Technology

[0002] The external device for automatic recovery of communication disconnection based on state layering is an external communication self-healing hardware module. At its core, it adopts a communication layered state machine to identify and handle link faults in a graded manner, distinguishing between instantaneous disturbances, virtual link disconnections, protocol loss of connection, and hardware failures. It executes differentiated automatic recovery strategies according to the grade, realizing the autonomous reconstruction of the link without human intervention after communication disconnection.

[0003] While existing devices can determine whether communication is interrupted, troubleshooting which communication layer is causing the problem requires manual inspection and troubleshooting layer by layer. This not only increases the workload of manual labor but also increases communication interruption time. Existing devices can only make simple judgments about communication connectivity, resulting in a single fault handling method and low market competitiveness. Therefore, this application provides an external device and method for automatic recovery of communication disconnection based on state layering to meet the requirements. Summary of the Invention

A wire through hole is provided at the bottom of the housing. A strip groove is provided on the front of the backplane.

[0006] Preferably, a grooved base plate is fixedly connected to the bottom of the outer casing, a column is fixedly connected to the bottom of the grooved base plate, an output terminal is fixedly connected to the bottom of the access box, an output signal line is threaded to one end of the output terminal, a hard socket is fixedly connected to the side of the access box, and a wireless signal base station is threaded to one end of the hard socket.

[0007] Preferably, the automatic recovery module includes a first expansion dock and a second expansion dock. Both the first expansion dock and the second expansion dock are connected to a base plate by bolts and threads on the upper expansion dock. The top of the first expansion dock is provided with a first main line, and the top of the second expansion dock is provided with a second main line.

[0008] Preferably, the bottom of the second expansion dock is provided with a first layer of status transmission line, a second layer of status transmission line, a third layer of status transmission line and a fourth layer of status transmission line from left to right, and one end of the first layer of status transmission line is provided with a first layer of electrical signal sensing unit.

[0009] Preferably, one end of the second-layer state transmission line is provided with a second-layer electrical signal sensing unit, one end of the third-layer state transmission line is provided with a third-layer electrical signal sensing unit, and one end of the fourth-layer state transmission line is provided with a fourth-layer electrical signal sensing unit.

[0010] Preferably, the back of the first layer electrical signal sensing unit, the second layer electrical signal sensing unit, the third layer electrical signal sensing unit and the fourth layer electrical signal sensing unit are all provided with onboard ribbon cables, and the onboard ribbon cables are threadedly connected to the base plate by onboard ribbon cable bolts.

[0011] Preferably, the front side of the onboard cable is provided with a first processing unit, a second processing unit, a third processing unit and a fourth processing unit from left to right.

[0012] Preferably, the bottom of the first layer processing unit, the second layer processing unit, the third layer processing unit and the fourth layer processing unit are provided with a transmission short line and a feedback processing line from front to back, and one end of the transmission short line is provided with a third expansion dock.

[0013] Preferably, the third expansion dock is bolted to a base plate via a lower expansion dock, the bottom of the third expansion dock is provided with a third main line, and an access box is installed in the third expansion dock via the third main line.

[0014] A method for automatically restoring external devices after communication disconnection based on state layering includes the following steps: Step 1: The base plate is used to house the automatic recovery module and access box. The outer shell protects the automatic recovery module, access box, and other related components from external damage. The hinged door can be opened and closed. If manual operation is required, the door must be opened to operate the structural components on the base plate. The output signal line allows the communication content in the main device to be transmitted to the terminal device. This is physical line transmission. The wireless signal base station converts the communication content of the main device into a wireless signal and transmits it to the terminal. When the output signal line is working normally, the wireless signal base station also has a synchronous hot start. Once the output signal line is damaged and cannot transmit communication content, the wireless signal base station can transmit the wireless signal to the terminal device, thereby restoring communication to the disconnected device. The automatic recovery module can automatically detect the communication layer status and automatically repair it when abnormal, thereby reducing manual workload, reducing communication downtime, enriching the device's fault handling methods, and enhancing the device's market competitiveness. Step 2: When the main device is normal, the communication content of each level is normal. When passing through each layer of electrical signal sensing unit, there is an electrical signal passing through. At this time, the electrical signal sensing unit will not enable the processing unit to work through the onboard cable. The communication content of each level can enter the third expansion dock through the transmission short line, then enter the access box through the third main line, and then be transmitted to the terminal device through both wired and wireless transmission. However, once the main device is abnormal, the communication content of each level may also be abnormal. When the communication content is output to the second main line, it will enter the second expansion dock, and then enter the electrical signal sensing unit of each level through the transmission line of each level. When abnormal communication content passes through the electrical signal sensing units of each layer, there will be no electrical signal when the abnormal communication content passes through the corresponding layer's electrical signal sensing unit. At this time, the corresponding layer's electrical signal sensing unit can transmit the start signal to the corresponding layer's processing unit through the onboard cable. The corresponding layer's processing unit then starts working, mainly by activating the repair program written in advance within the processing unit. This allows it to actively repair or actively build a temporary channel to repair or restore the abnormal part of the communication content. The program code is transmitted to the first expansion dock through the feedback processing line of the corresponding layer's processing unit, and then transmitted to the main device via the first main line to repair the internal communication content. After repair, the repaired communication content can be directly transmitted to the access box in the same way as before, and then transmitted to the terminal device through both wired and wireless transmission methods.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, the automatic recovery module can automatically detect whether the main device output signal is abnormal. When an abnormality occurs, it can actively repair it, making the whole process automated. This can reduce the workload of manual labor to a certain extent, and also reduce the time of communication interruption.

[0016] The automatic recovery module can not only detect communication anomalies, but also repair them autonomously. This makes the device's fault handling methods more diverse, which can help improve the device's competitiveness in the market to some extent.

[0017] In summary, the present invention has the advantages of being able to autonomously detect and repair communication, being fully automated without human intervention, reducing the intensity of manual labor and the time of communication interruption, enriching the ways in which the device can handle faults, and enhancing the market competitiveness of the device.

The output signal line 11 allows the communication content in the main device to be transmitted to the terminal device. This is physical line transmission. The wireless signal base station 13 can convert the communication content of the main device into a wireless signal and transmit it to the terminal signal. When the output signal line 11 is working normally, the wireless signal base station 13 also has a synchronous hot start.

[0034] The front of the onboard cable 313 is provided with a first layer processing unit 314, a second layer processing unit 315, a third layer processing unit 316 and a fourth layer processing unit 317 from left to right.

[0035] The bottom of the first-layer processing unit 314, the second-layer processing unit 315, the third-layer processing unit 316, and the fourth-layer processing unit 317 are provided with a transmission short line 318 and a feedback processing line 319 from front to back, and a third expansion dock 320 is provided at one end of the transmission short line 318.

[0036] The third expansion dock 320 is connected to the base plate 2 by bolts and threads from the lower expansion dock. The bottom of the third expansion dock 320 is equipped with a third main line 321, and the third expansion dock 320 is equipped with an access box 4 through the third main line 321.

[0037] Both the first expansion dock 301 and the second expansion dock 302 are fixed to the base plate 2 by bolts from the upper expansion dock. The first main line 303 is installed between the first expansion dock 301 and the main equipment, and the second main line 304 is installed between the second expansion dock 302 and the main equipment. The first-layer status transmission line 305, the second-layer status transmission line 306, the third-layer status transmission line 307, and the fourth-layer status transmission line 308 are installed in the second expansion dock 302 and the corresponding first-layer electrical signal sensing unit 309, second-layer electrical signal sensing unit 310, and third-layer electrical signal sensing unit 310.

[0038] When the main device is normal, the communication content of each level is normal. When passing through each level of electrical signal sensing unit, there is an electrical signal passing through. At this time, the electrical signal sensing unit will not make the processing unit work through the onboard cable 313. At this time, the communication content of each level can enter the third expansion dock 320 through the transmission short line 318, and then enter the access box 4 through the third main line 321. Then it is transmitted to the terminal device through both wired and wireless transmission. However, once the main device is abnormal, the communication content of each level may also be abnormal. When the communication content is output to the second main line 304, it will enter the second expansion dock 302, and then enter the electrical signal sensing unit of each level through the transmission line of each level. When abnormal communication content passes through the electrical signal sensing units of each layer, there is no electrical signal when the abnormal communication content passes through the corresponding layer electrical signal sensing unit. At this time, the corresponding layer electrical signal sensing unit can transmit the start signal to the corresponding layer processing unit through the onboard ribbon cable 313. At this time, the corresponding layer processing unit starts working, mainly to start the repair program written in advance in the corresponding layer processing unit, so as to actively repair or actively build a temporary channel to repair or restore the abnormal part of the communication content. The program code is transmitted to the first expansion dock 301 through the feedback processing line 319 of the corresponding layer processing unit, and then transmitted to the main device through the first main line 303 to repair the internal communication content. After repair, the repaired communication content can be directly transmitted to the access box 4 in the same way as before, and then transmitted to the terminal device through both wired and wireless transmission.

[0039] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0040] A method for automatically restoring external devices after communication disconnection based on state layering includes the following steps: Step 1: The base plate 2 is used to house the automatic recovery module 3 and the access box 4. The outer shell 5 is used to protect the automatic recovery module 3, access box 4, and other related components from external damage. The opening and closing door 7 can be opened and closed by the hinge 6. If manual operation is required, the opening and closing door 7 must be opened to operate the structural components on the base plate 2. The output signal line 11 allows the communication content in the main device to be transmitted to the terminal device. This is physical line transmission. The wireless signal base station 13 can convert the communication content of the main device into a wireless signal and transmit it to the terminal signal. When the output signal line 11 is working normally, the wireless signal base station 13 also has a synchronous hot start. Once the output signal line 11 is damaged and cannot transmit communication content, the wireless signal base station 13 can transmit the wireless signal of communication to the terminal device, thereby allowing the communication disconnected device to restore communication. The automatic recovery module 3 can automatically detect the communication layer status and can automatically repair it when abnormal, thereby reducing the intensity of manual work, reducing the communication disconnection time, enriching the device's fault handling methods, and enhancing the device's market competitiveness. Step 2: When the main device is normal, the communication content of each level is normal. When passing through each level of electrical signal sensing unit, there is an electrical signal passing through. At this time, the electrical signal sensing unit will not make the processing unit work through the onboard cable 313. At this time, the communication content of each level can enter the third expansion dock 320 through the transmission short line 318, and then enter the access box 4 through the third main line 321. Then it is transmitted to the terminal device through both wired and wireless transmission. However, once the main device is abnormal, the communication content of each level may also be abnormal. When the communication content is output to the second main line 304, it will enter the second expansion dock 302, and then enter the electrical signal sensing unit of each level through the transmission line of each level. When abnormal communication content passes through the electrical signal sensing units of each layer, there is no electrical signal when the abnormal communication content passes through the corresponding layer electrical signal sensing unit. At this time, the corresponding layer electrical signal sensing unit can transmit the start signal to the corresponding layer processing unit through the onboard ribbon cable 313. At this time, the corresponding layer processing unit starts working, mainly to start the repair program written in advance in the corresponding layer processing unit, so as to actively repair or actively build a temporary channel to repair or restore the abnormal part of the communication content. The program code is transmitted to the first expansion dock 301 through the feedback processing line 319 of the corresponding layer processing unit, and then transmitted to the main device through the first main line 303 to repair the internal communication content. After repair, the repaired communication content can be directly transmitted to the access box 4 in the same way as before, and then transmitted to the terminal device through both wired and wireless transmission.

[0041] The technical solution provided by this invention: The base plate 2 is used to house and install the automatic recovery module 3 and the access box 4. The outer shell 5 is used to protect the automatic recovery module 3, the access box 4, and other related components from external damage. The opening and closing door 7 can be opened and closed via the hinge 6. If manual operation is required, the opening and closing door 7 must be opened to operate the structural components on the base plate 2. The output signal line 11 allows the communication content in the main device to be transmitted to the terminal device; this is physical line transmission. The wireless signal base station 13 can convert the communication content of the main device into a wireless signal and transmit it to the terminal signal. When the output signal line 11 is working normally, the wireless signal base station 13 also... It features synchronous hot start. If the output signal line 11 is damaged and unable to transmit communication content, the wireless signal base station 13 can transmit the wireless signal to the terminal device, allowing the disconnected device to resume communication. The automatic recovery module 3 can automatically detect the communication layer status and automatically repair any abnormalities, thereby reducing manual workload, shortening communication downtime, enriching the device's fault handling methods, and enhancing its market competitiveness. When the main equipment is normal, the communication content at each layer is normal, and electrical signals pass through each layer's electrical signal sensing unit. At this time, the electrical signal sensing units at each layer will not enable the processing units at each layer to operate via the onboard cable 313. At this point, the communication content of each level can enter the third expansion dock 320 through the transmission short line 318, then enter the access box 4 through the third main line 321, and then be transmitted to the terminal device through both wired and wireless transmission. However, if the main device malfunctions, the communication content of each level may also be abnormal. When the communication content is output to the second main line 304, it will enter the second expansion dock 302, and then enter the electrical signal sensing unit of each level through the transmission lines of each level. When abnormal communication content passes through the electrical signal sensing unit of each level, there will be no electrical signal when the abnormal communication content passes through the corresponding level electrical signal sensing unit. At this time, the electrical signal sensing unit of the corresponding level is... The startup signal can be transmitted to the corresponding layer processing unit via the onboard cable 313. At this time, the corresponding layer processing unit starts to work, mainly to start the repair program written in advance within the corresponding layer processing unit. This allows it to actively repair or actively build a temporary channel to repair or restore abnormal parts of the communication content. The program code is transmitted to the first expansion dock 301 via the feedback processing line 319 of the corresponding layer processing unit, and then transmitted to the main device via the first main line 303 to repair the internal communication content. After repair, the repaired communication content can be directly transmitted to the access box 4 in the same way as before, and then transmitted to the terminal device via both wired and wireless transmission.

The bottom of the third expansion dock (320) is provided with a third main line (321). The third expansion dock (320) is equipped with an access box (4) through the third main line (321).

10. The method for using an external device to automatically recover from communication disconnection based on state layering according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1: The base plate (2) is used to place and install the automatic recovery module (3) and the access box (4). The outer shell (5) is used to protect the automatic recovery module (3) and the access box (4) and other related components from external damage. The opening and closing door (7) can be opened and closed by the hinge (6). If manual operation is required, the opening and closing door (7) must be opened to operate the structural components on the base plate (2). The output signal line (11) can transmit the communication content in the main device to the terminal device. This is a physical line transmission. The wireless signal base station (13) can transmit the communication content of the main device to the terminal device. The communication content is converted into a wireless signal and transmitted to the terminal signal. When the output signal line (11) is working normally, the wireless signal base station (13) is also synchronously hot-started. Once the output signal line (11) is damaged and cannot transmit the communication content, the wireless signal base station (13) can transmit the wireless signal of the communication to the terminal device, so that the communication disconnected device can resume communication. The automatic recovery module (3) can automatically detect the communication layer status and can automatically repair it when abnormal, thereby reducing the intensity of manual work, reducing the communication disconnection time, enriching the means of handling device faults, and enhancing the market competitiveness of the device. Step 2: When the main device is normal, the communication content of each level status is normal. When passing through each level electrical signal sensing unit, there is an electrical signal passing through. At this time, each level electrical signal sensing unit will not make each level processing unit work through the onboard cable (313). At this time, the communication content of each level status can enter the third expansion dock (320) through the transmission short line (318) and then enter the access box (4) through the third main line (321). Then it is transmitted to the terminal device through two methods: line transmission and wireless transmission. However, once the main device is abnormal, the communication content of each level status may also be abnormal. When the communication content is output to the second main line (304), it will enter the second expansion dock (302) and then enter the electrical signal sensing unit of each level through the transmission line of each level status respectively. When abnormal communication content passes through the electrical signal sensing units of each layer, there is no electrical signal when the abnormal communication content passes through the corresponding layer electrical signal sensing unit. At this time, the corresponding layer electrical signal sensing unit can transmit the start signal to the corresponding layer processing unit through the onboard ribbon cable (313). At this time, the corresponding layer processing unit starts working, mainly to start the repair program written in advance in the corresponding layer processing unit, so as to actively repair or actively build a temporary channel to repair or open up the abnormal part in the communication content. The program code is transmitted to the first expansion dock (301) through the feedback processing line (319) of the corresponding layer processing unit, and then transmitted to the main device through the first main line (303) to repair the internal communication content. After repair, the repaired communication content can be directly transmitted to the access box (4) in the same way as before, and then transmitted to the terminal device through two methods: line transmission and wireless transmission.
