[ background ] A method for producing a semiconductor device
In a computer device operating system, there is usually an information notification about the status of network connection, such as: whether the network connection state graphic representation is normal or not is displayed on the screen or whether the network connection state graphic representation is normal or not is displayed through the light-up information of the lamp number so as to indicate the network connection state of the computer device and the external device. Generally, in order to increase the number of network ports, the network port of the computer device is connected to an external Hub (Ethernet Hub), and then connected to the financial payment unit through the Hub to form a network connection.
Nowadays, an external hub is integrated into a computer device, so that a user does not need to prepare the hub in a troublesome way, and the convenience and the integrity of the computer device are greatly improved. The network port of the computer device is directly connected with the internal hub by a physical line and is connected to the external network gateway through the hub to form network connection. However, when the line is disconnected between the hub and the financial payment unit, because the network connection status detected by the computer device refers to the network connection status between the hub and the network port directly connected to the computer device, and the network port is directly connected to the built-in hub by the physical circuit, the computer device cannot detect the disconnection status between the network port and the built-in hub, and will not start the abnormal repairing procedure of the network connection in real time, so that the computer device cannot judge the disconnection status of the network by hardware in real time through the network port, the computer device will wait for a period of time and transmit and receive signals for many times by software, and will not receive correct responses, then will start to perform complex and time-consuming calculations with software to detect the situation that the network port cannot be connected to the network, and lead to the computer device to judge whether to successfully connect to the external network for a long time, which will result in that the disconnection status of the network cannot be detected in real time, further research and improvement by practitioners are highly needed.

Fig. 1 is a block diagram illustrating an embodiment of a network detection system according to the present invention.
[ detailed description ] embodiments
Referring to fig. 1, the embodiment of the network detection system of the present invention includes a main board unit 1, a processing unit 2 disposed on the main board unit 1, a main connection port unit 3 disposed on the main board unit 1 and connected to the processing unit 2, a hub 4 disposed on the main board unit 1 and connected to the main connection port unit 3, a financial payment unit 5 network gateway 51 connected to the hub 4, a financial payment device 52 connected to the hub 4, and a circuit unit 6 connected to the main connection port unit 3 and the financial payment unit 5 network gateway 51.
The main port unit 3 includes a main port 31 and a detection pin 32. The hub 4 comprises a network connection port 41 connected to the main connection port 31, a network communication module 42 connected to the financial payment unit 5 network gateway 51 financial payment device 52. The financial payment unit 5 includes a network gateway 51 connected to the network communication module 42 of the hub 4, and a financial payment device 52 connected to the network communication module 42 of the hub 4. The network communication module 42 has a first network communication port 421 connected to the network gateway 51 and a second network communication port 422 connected to the financial payment device 52. The network gateway 51 includes a first pin 511. The financial payment device 52 includes a second connection pin 521. In this embodiment, the main board unit 1 is a single main board, and the processing unit 2, the main connecting port unit 3 and the hub 4 are conveniently disposed on the main board unit 1, but not limited thereto, the main board unit 1 can be designed as a plurality of main boards according to actual requirements, and the processing unit 2, the main connecting port unit 3 and the hub 4 are respectively disposed on corresponding main boards according to the design.
The circuit unit 6 has an input module 61 connected to the financial payment unit 5, and an output 62 connected to the detection pin 32 of the main port unit 3. The input module 61 has a first input 611 connected to the first pin 511 of the network gateway 51 and a second input 612 connected to the second pin 521 of the financial payment device 52. The processing unit 2 is connected to the network connection port 41 of the hub 4 via the primary connection port 31 of the primary connection port unit 3 and connected to the network gateway 51 via the first network communication port 421 of the network communication module 42 to form a network connection. When the first network communication port 421 forms a network connection through the network gateway 51, the first connection pin 511 of the network gateway 51 transmits a connection normal status message to the first input end 611 of the circuit unit 6, and the circuit unit 6 generates a network connection message according to the received connection normal status message and transmits the network connection message to the detection pin 32 through the output end 62, and when the processing unit 2 detects that the detection pin 32 receives the network connection message, it will not send a network anomaly notification message and send a network normal notification message. When the processing unit 2 cannot form a network connection through the network gateway 51 via the first network communication port 421, the first network communication port 421 of the network connection port 41 of the hub 4 is abnormally connected with the network gateway 51 to cause a network connection disconnection, the processing unit 2 is connected with the network connection port 41 via the main connection port 31 and is connected to the financial payment device 52 via the second network communication port 422 of the network communication module 42 to form a network connection, and when the second network communication port 422 forms a network connection via the network gateway 51, the second connection pin 521 of the financial payment device 52 transmits the connection normal status information to the second input end 612 of the circuit unit 6, and the circuit unit 6 generates the network connection information and transmits the network connection information to the detection pin 32 via the output end 62 when receiving the connection normal status information, when the processing unit 2 detects that the detection pin 32 receives the network connection information, it sends out the network normal notification information. That is, as long as the circuit unit 6 receives the link normal status information via the first input end 611 or receives the link normal status information via the second input end 612, the circuit unit 6 generates the network connection information and transmits the network connection information to the detection pin 32 via the output end 62, and the processing unit 2 sends the network normal notification information when detecting that the detection pin 32 receives the network connection information; in contrast, if the detection pin 32 of the main port unit 3 does not receive the network connection information, the processing unit 2 cannot detect that the detection pin 32 receives the network connection information, and at this time, the processing unit 2 sends the network anomaly notification message. In this embodiment, it is preset that the processing unit 2 forms a network connection through the network gateway 51 via the first network communication port 421, and if the connection between the first network communication port 421 and the network gateway 51 is abnormal, the processing unit 2 automatically connects to the network connection port 41 via the main connection port 31 and connects to the financial payment device 52 via the second network communication port 422 to form a network connection, but not limited thereto.
When the first network communication port 421 of the network communication module 42 cannot form a network connection through the network gateway 51, the first connection pin 511 of the network gateway 51 transmits an abnormal status message to the first input end 611 of the circuit unit 6, and when the processing unit 2 cannot form a network connection through the financial payment device 52 via the second network communication port 422 of the network communication module 42, the second connection pin 521 of the financial payment device 52 transmits the abnormal status message to the second input end 612 of the circuit unit 6. At this time, it represents that the network connection is broken due to the abnormal connection between the first network communication port 421 of the hub 4 and the network gateway 51, and the second network communication port 422 of the hub 4 and the financial payment device 52 are also abnormal, which causes the network connection to be broken. Conversely, when the circuit unit 6 does not receive at least one of the connection normal state information, the network connection information is not generated and is not transmitted to the detection pin 32, and at this time, when the detection pin 32 of the main port unit 3 does not receive the network connection information, the processing unit 2 cannot detect that the detection pin 32 receives the network connection information and sends the network abnormality notification information. Further, in this embodiment, when the circuit unit 6 receives the abnormal state information via the first input end 611 and the abnormal state information via the second input end 612, the network disconnection information is generated and transmitted to the detection pin 32 via the output end 62, and when the processing unit 2 detects the network disconnection information received by the detection pin 32 of the main port unit 3, the network abnormality notification information is sent.
It should be particularly noted that, in the embodiment, the circuit unit 6 is a logic gate (Or gate ) state (not shown), the abnormal state information and the network disconnection information are both low level signals, the link normal state information and the network connection information are both high level signals, and since the circuit unit 6 is a logic gate (Or gate) state, the output end 62 of the logic gate generates the network connection information (high level signal) and transmits the network connection information (high level signal) to the detection pin 32 through the output end 62 only when the first input end 611 of the circuit unit 6 receives the link normal state information (high level signal) Or the second input end 612 receives the link normal state information (high level signal), and when the processing unit 2 receives the network connection information received by the detection pin 32, sending out normal notification information of the network; only when the first input end 611 of the circuit unit 6 receives the abnormal state information (low level signal) and the second input end 612 receives the abnormal state information (low level signal), the output end 62 of the logic gate circuit generates the network disconnection information (low level signal) and transmits the network disconnection information to the detection pin 32 through the output end 62, and the processing unit 2 sends the network abnormality notification information when receiving the network disconnection information received by the detection pin 32. In short, the processing unit 2 will send out the network normal notification message as long as there exists one of the first network communication port 421 of the hub 4 forming the network connection with the network gateway 51 or the second network communication port 422 forming the network connection with the financial payment device 52; conversely, the processing unit 2 will only send the network anomaly notification message if the first network communication port 421 of the hub 4 is disconnected from the network gateway 51 and the second network communication port 422 is disconnected from the financial payment device 52. In this embodiment, the first network communication port 421 of the network communication module 42 of the hub 4 is used to connect the network gateway 51 and the second network communication port 422 to the financial payment device 52, so that when the first network communication port 421 cannot form a network connection through the network gateway 51, the network connection can be formed by connecting the second network communication port 422 to the financial payment device 52, but not limited thereto. It can also be designed according to the actual requirement, that only the first network communication port 421 of the network communication module 42 of the hub 4 is used to connect to the network gateway 51, and when the first network communication port 421 forms a network connection through the network gateway 51, the first connection pin 511 of the network gateway 51 transmits the connection normal state information to the first input end 611 of the circuit unit 6, and the circuit unit 6 generates the network connection information according to the received connection normal state information and transmits the network connection information to the detection pin 32 through the output end 62, and when the processing unit 2 detects that the network connection information is received by the detection pin 32, the network normal notification information is transmitted; if the network connection information is not received by the detection pin 32 of the main port unit 3, the processing unit 2 cannot detect that the network connection information is received by the detection pin 32, and at this time, the processing unit 2 sends the network anomaly notification information, that is, because only the first network communication port 421 of the network communication module 42 of the hub 4 is used to connect the network gateway 51, when the first network communication port 421 cannot form a network connection through the network gateway 51, the first connection pin 511 of the network gateway 51 transmits the anomaly status information to the first input end 611 of the circuit unit 6, and the circuit unit 6 generates the network disconnection information and transmits the network disconnection information to the detection pin 32 through the output end 62, and when the processing unit 2 detects the network disconnection information received by the detection pin 32 of the main port unit 3, and sending the network abnormity notification information.

If the network connection information is not received by the detection pin 32 of the main port unit 3, and the processing unit 2 cannot detect that the network connection information is received by the detection pin 32, at this time, the processing unit 2 immediately sends the network abnormal notification information, further, when the circuit unit 6 cannot perform network connection through the network gateway 51 and cannot perform network connection through the financial payment device 52 at the same time, the first connection pin 511 of the network gateway 51 transmits the abnormal state information to the first input end 611 and the second connection pin 521 of the financial payment device 52 to transmit the abnormal state information to the second input end 612, and the circuit unit 6 receives the abnormal state information and the abnormal state information at the same time to generate the network disconnection information and transmit the network disconnection information to the detection pin 32 through the output end 62, when the processing unit 2 receives the network disconnection information through the main port unit 3, it immediately sends out the network abnormal notification information, so as to let the user immediately know the network disconnection status.
