[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described here can be implemented in an order other than that illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions.

[0044] like Figure 1 As shown, the utility model provides a surge protection device with state monitoring and bypass linkage functions, the surge protection device comprising:

[0045] Surge protection module 101, bypass linkage module 102, monitoring module 103, backup path 106, protection end network port 104 and surge end network port 105; protection end network port 104 is used to connect to the near-end protection device; surge end network port 105 is used to connect to the remote device;

[0046] The monitoring module 103 is connected to the surge protection module 101 and the bypass linkage module 102 respectively;

[0047] The protection end network port 104 is connected to one end of the bypass linkage module 102;

[0048] The surge end network port 105 is connected to the other end of the bypass linkage module 102;

[0049] The monitoring module 103 is used to send an activation instruction to the bypass linkage module 102 when the working state of the surge protection module 101 is a failure state or is about to fail;

[0050] The bypass linkage module 102 is used to connect to the surge protection module 101 before receiving the activation instruction; after receiving the activation instruction, disconnect from the surge protection module 101 and connect to the backup path 106.

[0051] The surge protection module 101 is used to directly resist surges and protect the connected circuits from the impact of high voltage electricity. The monitoring module 103 detects the working state of the surge protection module 101 based on the key performance parameters of the surge protection module 101. The working state of the surge protection module 101 includes a normal state, an imminent failure state, and a failure state. The key performance parameters of the surge protection module 101 include the voltage, leakage current, discharge times, discharge energy, discharge energy peak, and temperature parameters of the surge protection module 101.

[0052] When the monitoring module 103 detects that the working state of the surge protection module 101 is in a normal state, one end of the bypass linkage module 102 is connected to one end of the surge protection module 101, and the other end of the bypass linkage module 102 is connected to the other end of the surge protection module 101. When the monitoring module 103 detects that the working state of the surge protection module 101 is in a failed state or a state about to fail, the monitoring module 103 sends an activation instruction to the bypass linkage module 102. After receiving the activation instruction, the bypass linkage module 102 disconnects from the surge protection module 101 and connects to the backup path 106. Thus, by automatically disconnecting the circuit from the surge protection module 101 and connecting to the backup path 106 when it is detected that the surge protection module 101 is in a state about to fail or a failed state, the internal circuit in the surge protection device can still be connected even if the surge protection module 101 fails, thereby avoiding data loss caused by the failure of the surge protection module 101.

[0053] like Figure 2 As shown, in an optional embodiment, the monitoring module 103 includes: a detection module 201, a data processing module 202 and a watchdog module 203;

[0054] The detection module 201 is connected to the surge protection module 101 and the data processing module 202 respectively;

[0055] The data processing module 202 is connected to the watchdog module 203;

[0056] The watchdog module 203 is connected to the bypass linkage module 102;

[0057] The detection module 201 is used to monitor the performance parameters of the surge protection module 101;

[0058] The data processing module 202 is used to determine the working state of the surge protection module 101;

[0059] The watchdog module 203 is used to send an activation instruction to the bypass linkage module 102 when the surge protection module 101 is in a failed state or is about to fail.

[0060] The detection module 201 collects performance parameters of the surge protection module 101 and feeds the collected performance parameters back to the data processing module 202. The data processing module 202 analyzes and processes the performance data to determine the working status of the surge protection module 101.

[0061] The watchdog module 203 specifically includes a timer circuit, which is connected to the data processing module 202 and the bypass linkage module 102 respectively. When the timer counts down to 0, the watchdog module 203 sends an activation instruction to the bypass linkage module 102. When the data processing module 202 determines that the working state of the surge protection module 101 is normal, it sends a restoration instruction to the timer circuit in the watchdog module 203, so that the count of the timer is restored to a preset value, and restarts to count down from the preset value, so as to avoid the watchdog module 203 triggering the activation instruction when the working state of the surge protection module 101 is a normal working state.

[0062] When the data processing module 202 determines that the working state of the surge protection module 101 is a failure state or is about to fail, the data processing module 202 no longer sends a recovery instruction to the timer in the watchdog module 203, so that the timer counts down to zero, triggering the action of sending an activation instruction to the bypass linkage module 102.

[0063] like Figure 3 As shown, in an optional embodiment, the bypass linkage module 102 includes a first relay 302 and a second relay 303; the backup path 106 includes a connecting line 301;

[0064] The input end of the first relay 302 is connected to the protection end network port 104;

[0065] The input end of the second relay 303 is connected to the surge end network port 105;

[0066] Before the bypass linkage module 102 receives the activation instruction, the output end of the first relay 302 is connected to one end of the surge protection module 101; the output end of the second relay 303 is connected to the other end of the surge protection module 101;

[0067] After the bypass linkage module 102 receives the activation instruction, the output end of the first relay 302 is connected to one end of the connection line 301 ; the output end of the second relay 303 is connected to the other end of the connection line 301 .

[0068] When the surge protection module 101 is in normal working state, the bypass linkage module 102 does not receive the activation instruction, the output end of the first relay 302 is connected to one end of the surge protection module 101, and the output end of the second relay 303 is connected to the other end of the surge protection module 101, so that the surge protection module 101 is connected to the bypass linkage module 102, which plays a role in preventing surges from damaging other devices in the circuit.

[0069] When the surge protection module 101 is in a failed state or is about to fail, the bypass linkage module 102 receives an activation instruction and switches the output end of the first relay 302 from being connected to one end of the surge protection module 101 to being connected to one end of the connection line 301. The output end of the second relay 303 is connected to the other end of the surge protection module 101 and is switched to being connected to the other end of the connection line 301. Thus, when the surge protection module 101 is in a failed state or is about to fail, the bypass linkage module 102 automatically switches from the branch where the surge protection module 101 is located to the backup path 106, so that the network message data can directly enter from the protection end network port 104 and output from the surge end network port 105 to ensure the data transmission function.

[0070] like Figure 4 In an optional embodiment, the bypass linkage module 102 further includes a first relay 302 and a second relay 303; the backup path 106 includes a fault indicator light 401;

[0071] The input end of the first relay 302 is connected to the protection end network port 104;

[0072] The input end of the second relay 303 is connected to the surge end network port 105;

[0073] The bypass linkage module 102 is connected to the detection module 201;

[0074] Before the bypass linkage module 102 receives the activation instruction, the output end of the first relay 302 is connected to one end of the surge protection module 101; the output end of the second relay 303 is connected to the other end of the surge protection module 101;

[0075] After the bypass linkage module 102 receives the activation instruction, the output end of the first relay 302 is connected to one end of the fault indicator light 401 ; the output end of the second relay 303 is connected to the other end of the fault indicator light 401 .

[0076] The fault indicator light 401 in the bypass linkage module 102 is connected to the detection module 201 in the monitoring module 103. When the surge protection module 101 is in a failed state or is about to fail, the bypass linkage module 102 receives an activation instruction and switches the output end of the first relay 302 from being connected to one end of the surge protection module 101 to being connected to one end of the fault indicator light 401. The output end of the second relay 303 is connected to the other end of the surge protection module 101 and switched to being connected to the other end of the fault indicator light 401. Thus, when the surge protection module 101 is in a failed state or is about to fail, the surge protection module 101 can be removed and the fault indicator light 401 can be turned on. Since the bypass linkage module 102 is connected to the detection module 201, the detection module 201 can obtain the state of the fault indicator light 401, so that the detection module 201 can determine in real time whether the state of the fault indicator light 401 is turned on, so that when the fault indicator light 401 is turned on, the detection module 201 can remind the staff that the surge protection module 101 is in a failed state or is about to fail.

[0077] It should be noted that the fault indicator light 401 has different colors when it is turned on and when it is turned off.

[0078] In the utility model, the protection end network port 104 is connected to the 1st pin, the 2nd pin, the 3rd pin and the 6th pin of one end of the network cable, and the surge end network port 105 is connected to the 1st pin, the 2nd pin, the 3rd pin and the 6th pin of the other end of the network cable, so as to realize data transmission between the protection end network port 104 and the surge end network port 105 through the connection network cable. The 4th pin and the 5th pin of the protection end network port 104 are used as the positive pole of the power supply, and the 7th pin and the 8th pin of the surge end network port 105 are used as the negative pole of the power supply. In an optional embodiment, the utility model specifically connects the input end of the first relay 302 to the 4th pin of the protection end network port 104, and connects the input end of the second relay 303 to the 7th pin of the surge end network port 105. When the surge protection module 101 is in a failed state or is about to fail, a potential difference is formed between the 4th pin of the protection end network port 104 and the 7th pin of the surge end network port 105, so as to ensure that the fault indicator light 401 can work normally.

[0079] like Figure 5 , In an optional embodiment, the surge protection device further includes: a communication module 501;

[0080] The communication module 501 is connected to the data processing module 202;

[0081] The communication module 501 is used to integrate the performance parameters and working status of the surge protection module 101 into the Internet of Things.

[0082] The communication module 501 is connected to the client, the Internet and the cloud, so that the communication module 501 can integrate the real-time data and status reports of the data processing module 202 and the surge protection module into the Internet, providing convenience for remote monitoring and control and increasing the flexibility of management and operation and maintenance.

[0083] It should be noted that when the backup path 106 includes a fault indicator light 401, the communication module 501 is also used to integrate the status of the fault indicator light 401 into the Internet of Things, so as to remind the staff through the status of the fault indicator light 401 that the surge protection module 101 is in a failed state or is about to fail.

[0084] A surge protection module 101, a bypass linkage module 102, a monitoring module 103, a backup path 106, a protection end network port 104 and a surge end network port 105 are arranged in the surge protection device. The protection end network port 104 is used to connect the near-end protection device, and the surge end network port 105 is used to connect the remote device. The monitoring module 103 is connected to the surge protection module 101 and the bypass linkage module 102 respectively, the protection end network port 104 is connected to one end of the bypass linkage module 102, and the surge end network port 105 is connected to the other end of the bypass linkage module 102. The monitoring module 103 is used to send an activation instruction to the bypass linkage module 102 when the working state of the surge protection module 101 is a failure state or is about to fail. The bypass linkage module 102 is used to connect to the surge protection module 101 before receiving the activation instruction, and disconnect from the surge protection module 101 after receiving the activation instruction, and connect to the backup path 106. Therefore, when it is detected that the surge protection module 101 is in a state of being about to fail or in a failed state, the connection between the circuit and the surge protection module 101 is automatically disconnected and connected to the backup path 106, so as to realize automatic removal of the surge protection module 101 that is in a failed state or is about to fail, so that the line in the surge protection device after the surge protection module 101 is removed maintains the path, thereby avoiding data loss caused by the failure of the surge protection module 101.
