[0033] An embodiment of the present application provides a detection line fault test device 116. Figure 1 It is a schematic diagram of a detection line fault test device provided by an embodiment of the present application. As Figure 1 shown, the test device includes: at least one test port 112; at least one detection port 111; a detection line 115, which is configured to be connected to the test port 112 at one end and to the detection port 111 or electrically connected to a detection device at the other end, and the detection device is used to obtain detection data that can characterize blood glucose concentration; the detection line 115 is composed of multiple single lines; a test module 110, which is connected to the test port 112, the detection port 111, and the detection line 115 to form a test circuit, and the test circuit is used to test the line state of the detection line 115; the test module 110 is used to send different input levels to the multiple single lines in the detection line 115 respectively, and to obtain the output levels corresponding to the multiple single lines in the detection line 115 respectively; and an output module 113, which outputs a signal indicating the line state of the detection line 115 in response to the test result of the test module 110. The detection device includes a sensor, and the sensor is used to obtain detection data that can characterize blood glucose concentration.

[0034] Specifically, as Figure 1 shown, the test device in the embodiment of the present application includes at least one test port 112. Through the test port 112, the test device can access the detection line 115 to be tested. During the test, the detection port 111 in the embodiment of the present application is connected to the input end of the detection line 115, and the test port 112 is connected to the output end of the detection line 115. Thus, through the test module 110, a test circuit is formed by connecting to the test port 112, the detection port 111, and the detection line 115. The detection line 115 in the test device is composed of multiple single lines. These single lines are used to transmit different signals. One end of the detection line 115 is connected to the test port 112, and the other end is connected to the detection port 111.

[0035] Furthermore, as Figure 1 shown, the test module 110 in the test device is responsible for sending different input levels, such as high level, low level, etc., to the multiple single lines in the detection line 115 respectively. At the same time, the test module 110 is also responsible for obtaining the output levels corresponding to the multiple single lines in the detection line 115 respectively. By comparing the input and output levels, the test module 110 can judge the line state of the detection line 115, such as whether it is open circuit, short circuit or normal state, etc. According to the test result of the test module 110, the output module 113 in the test device will output a corresponding signal to indicate the line state of the detection line 115. These signals can be digital signals, analog signals or optical signals, etc., and can be displayed or prompted to the user through devices such as a display screen, an indicator light, etc.

[0036] The test device in the embodiments of the present application can test multiple single wires in the detection line 115 simultaneously, improving the test efficiency. By comparing the input and output levels, the test module 110 can accurately judge the line state of the detection line 115, avoiding the errors that may occur in traditional manual testing.

[0037] After the detection line 115 is tested, if the detection line is normal, the connection port at the output end of the detection line 115 is electrically connected to the detection device, where the detection device is used to obtain detection data that can characterize the blood glucose concentration. Thus, the conversion from the detection by the detection line to the blood glucose concentration detection can be achieved.

[0038] In a feasible implementation manner, Figure 2 is a schematic diagram of a detection line fault test device provided by the embodiments of the present application. Figure 2 As shown, the multiple single wires at least include a blank electrode wire, a working electrode wire, a reference electrode wire, a counter electrode wire, and a shielding wire. The shielding wire is a metal wire wrapped outside the blank electrode wire, the working electrode wire, the reference electrode wire, and the counter electrode wire. The shielding wire is used to shield interference signals.

[0039] In one embodiment, a complete detection line 115 includes a working electrode wire, a blank electrode wire, a reference electrode wire, and a counter electrode wire. It is required that the ends of each of these four wires be connected, and there should be no short circuit between any two of them. In addition, it also includes a shielding wire wrapped outside these four wires. The shielding wire is a metal wire and is used to shield interference signals.

[0040] The test module 110 in the embodiments of the present application detects whether the working electrode wire, the blank electrode wire, the reference electrode wire, the counter electrode wire, and the shielding wire are short-circuited or open-circuited. After ensuring the normal line condition, the detection line 115 is used to test the multi-channel sensor 117.

[0041] In a feasible implementation manner, as Figure 1 shown, the test device further includes a user-side connection port for transmitting the test result of the detection line 115 to the user side 114.

[0042] In one embodiment, the user-side connection port can be interfaces such as USB, Ethernet, serial port, Bluetooth, etc. Through the user-side connection port, the test device can transmit the test result of the detection line 115 to the user side 114 in real time or in batches. After receiving the test result, the user side 114 can perform processing such as displaying, analyzing, and storing the test result.

[0043] Through the user-side connection port, the user can obtain the test result of the detection line 115 in real time. Secondly, the user side 114 has powerful data processing and analysis capabilities, and can quickly and accurately process and analyze a large number of test results, improving the test efficiency and quality.

[0044] In a feasible implementation, as Figure 1 shown, the line state of the detection line 115 includes a normal state and an abnormal state. The abnormal state includes an open circuit state and a short circuit state.

[0045] Specifically, the open circuit state means that a part or all of the detection line 115 is disconnected, resulting in the inability to transmit signals or power. The short circuit state means that a part or all of the detection line 115 has an abnormal low-impedance connection, resulting in an abnormal increase in current, which may damage equipment or cause dangers such as fires.

[0046] In a feasible implementation, as Figure 1 shown, the test module 110 is used to send a first level to the current single line to be tested in the detection line 115, and send a second level to other single lines in the detection line 115. Among them, the current single line to be tested is any single line in the detection line 115. Among them, the first level is different from the second level.

[0047] In one embodiment, the first level is generated by the test module 110 and sent to the current single line to be tested. The second level is a signal sent to other non-tested single lines in the detection line 115, and its function is to provide a comparison so that the test module 110 can accurately detect and analyze the response of the single line to be tested. The test module 110 evaluates the state of the detection line 115 by comparing the responses of different single lines to these two levels.

[0048] In the embodiment of the present application, by sending different level signals to different single lines, the test module 110 can more accurately evaluate the state of the detection line 115. The error rate generated during the manual detection of the detection line 115 is reduced.

[0049] In a feasible implementation, as Figure 1 shown, the signal corresponding to the open circuit state is: the input end of the current single line to be tested corresponds to the first level, and the input ends of other single lines in the detection line 115 respectively correspond to the second level. The level output by the output end of the current single line to be tested is different from the first level, and the levels output by the output ends of other single lines in the detection line 115 are different from the first level or the same as the second level.

[0050] Specifically, when performing an open circuit detection on the detection line 115, a first level is input to the input end of the current single line to be tested, and a second level different from the first level is input to other single lines in the detection line 115. Because in the case of an open circuit, current or signals cannot be transmitted from the input end to the output end. Therefore, when the current single line to be tested is in an open circuit state, its output end does not output the first level. For other single lines in the detection line 115, the output end will also not output the first level like the single line to be tested or correspondingly output the second level.

[0051] Taking the test module 110 in the test device as an example of the wire detection circuit board, the detection wire 115 includes 5 single wires, namely: shield wire, BE wire, WE wire, RE wire, and CE wire. The A end of the detection wire 115 is connected to the output end of the wire detection circuit board, and the B end of the detection wire 115 is connected to the input end of the wire detection circuit board. The wire detection circuit board is connected to the user terminal 114 through a USB cable.

[0052] In one embodiment, as Figure 2 shown, taking the detection of the line state of the shield wire as an example, the steps for detecting whether the shield wire is open are as follows: The detection circuit in the test module 110 sends a high level to the A end of the shield wire, a low level to the A end of the BE wire, a low level to the A end of the WE wire, a low level to the A end of the RE wire, and a low level to the A end of the CE wire. Then, the detection circuit will detect the B end level of the shield wire, the B end level of the BE wire, the B end level of the WE wire, the B end level of the RE wire, and the B end level of the CE wire. If the B end of the shield wire does not output the high level when the A end of the shield wire outputs a high level, it is determined that the shield wire is in an open state. At this time, the B ends of the BE wire, WE wire, RE wire, and CE wire do not output the high level correspondingly or output a low level correspondingly.

[0053] Similarly, when detecting the open circuit of the BE wire, WE wire, RE wire, and CE wire, the detection method is the same as that of the shield wire. A high level is input to the A end of the single wire to be detected, and low levels are input to the A ends of the other single wires respectively. Then, the output end levels of each single wire are detected to determine whether each single wire is in an open state. This is not elaborated in the embodiments of the present application.

[0054] In a feasible implementation manner, as Figure 1 shown, the signals corresponding to the short - circuit state are: the input end of the current single wire to be detected corresponds to a first level, and the input ends of the other single wires in the detection wire 115 correspond to a second level respectively. The output end of the current single wire to be detected corresponds to the first level, and the output ends of at least one other single wire in the detection wire 115 correspond to the first level.

[0055] Specifically, the input end of the current single wire to be detected corresponds to a first level, usually a high level, and the input ends of the other single wires in the detection wire 115 correspond to a second level, usually a low level. If the output end of the current single wire to be detected corresponds to the first level, and the output ends of at least one other single wire in the detection wire 115 also correspond to the first level, since the short - circuit state may cause the output ends of other single wires to be pulled up to the first level, it indicates that the current single wire to be detected is in a short - circuit state.

[0056] In one embodiment, as Figure 1 、 Figure 2As shown, taking the detection of the short - circuit line state of the shielded wire as an example, the detection circuit in the test module 110 sends a high level to the A - end of the shielded wire, a low level to the A - end of the BE wire, a low level to the A - end of the WE wire, a low level to the A - end of the RE wire, and a low level to the A - end of the CE wire. Then, the detection circuit detects the level at the B - end of the shielded wire, the level at the B - end of the BE wire, the level at the B - end of the WE wire, the level at the B - end of the RE wire, and the level at the B - end of the CE wire. If the level at the B - end of the shielded wire is high and the level at the B - end of one or more of the BE - end, WE - end, RE - end, and CE - end is also high, it is determined that there is a short - circuit between the shielded wire and other single wires.

[0057] Similarly, when detecting the short - circuit of the BE wire, WE wire, RE wire, and CE wire, the detection method is the same as that for the shielded wire. A high level is input to the A - end of the single wire to be detected, and low levels are respectively input to the A - ends of other single wires. Then, the levels at the output ends of each single wire are detected to determine whether each single wire is in a short - circuit state. This is not elaborated in this embodiment of the present application.

[0058] In a feasible implementation, as Figure 1 shown, the signals corresponding to the normal state are: the input end of the current single wire to be detected corresponds to the first level, and the input ends of other single wires in the detection line 115 respectively correspond to the second level. The output end of the current single wire to be detected corresponds to the first level, and the output ends of other single wires in the detection line 115 correspond to the second level.

[0059] Specifically, a first level, usually in a high - level state, is input to the input end of the single wire to be detected, and a second level, usually in a low - level state, is respectively input to the input ends of other single wires in the detection line 115. If the output end of the current single wire to be detected corresponds to the first level and the output ends of other single wires in the detection line 115 correspond to the second level, it indicates that the current single wire to be detected is in a normal state.

[0060] In one embodiment, as Figure 1 、 Figure 2 shown, taking the detection of the normal line state of the shielded wire as an example, the detection circuit in the test module 110 sends a high level to the A - end of the shielded wire, a low level to the A - end of the BE wire, a low level to the A - end of the WE wire, a low level to the A - end of the RE wire, and a low level to the A - end of the CE wire. Then, the detection circuit detects the level at the B - end of the shielded wire, the level at the B - end of the BE wire, the level at the B - end of the WE wire, the level at the B - end of the RE wire, and the level at the B - end of the CE wire. If the level at the B - end of the shielded wire is high, the level at the B - end of the BE wire is low, the level at the B - end of the WE wire is low, the level at the B - end of the RE wire is low, and the level at the B - end of the CE wire is low, then the current single wire to be detected is tested as being in a normal state.

[0061] Similarly, when performing a short - circuit detection on the BE line, WE line, RE line, and CE line, the detection method is the same as that for the shielded line. A high level is input to the A - end of the single line to be detected, and low levels are respectively input to the A - ends of other single lines. Then, the levels of the output ends of each single line are detected to determine whether each single line is in a normal state. This is not elaborated in the embodiments of this application.

[0062] In a feasible implementation manner, the embodiments of this application provide a multi - channel data detection system 119 including a test device. Figure 3 This is a schematic diagram of a multi - channel data detection system 119 provided by the embodiments of this application, as Figure 3 shown. The detection system includes: a sensor 117, connected to a detection port 111 through a detection line 115, for detecting detection data representing the concentration of an analyte solution; the test device further includes a data acquisition module 120, and the data acquisition module 120 is used to acquire all detection data; multiple sensors 117 correspond to the same data acquisition module 120; a user terminal 114, connected to the test device through a user - terminal connection port, and the user terminal is used to receive all detection data and the test results of the test device.

[0063] In one embodiment, the multi - channel data detection system 119 is used to acquire and analyze concentration data corresponding to an analyte in an electrochemical test cell 118. The detection system includes a sensor 117, and each electrochemical test cell 118 corresponds to a sensor 117. Multiple sensors 117 correspond to the same data acquisition module 120. In the embodiments of this application, the data acquisition module 120 and the test device can be integrated into one body. The data acquisition module 120 sends the detection data sent by multiple sensors 117 to the user terminal. The user terminal is connected to the test device through a user - terminal connection port. The user terminal can acquire the detection data sent by the data acquisition module 120 and is also used to acquire the test results of the detection line 115 sent by the test device.

[0064] Further, when the test result of the state of the detection line 115 meets the preset requirements, that is, in the normal state, one end of the detection line 115 is connected to the sensor 117 in the electrochemical test cell 118, and the other end is connected to the detection port 111. At this time, the detection line 115 is used to send the detection data acquired by the sensor 117 to the data acquisition module 120.

[0065] By integrating the data acquisition module 120 with the test device in the embodiments of this application, the high integration of the system is realized, and the complexity of the system is reduced. The detection system introduces the function of testing the state of the detection line 115. Only when the state of the detection line 115 meets the preset requirements, it is connected to the sensor 117 in the electrochemical test cell 118, thereby ensuring the accuracy and reliability of data transmission and avoiding false detection or missed detection caused by the failure of the detection line 115.

[0066] In a feasible implementation manner, the client 114 is provided with a test function module for detecting the state of the detection line 115. The test function module is used to start a preset line state test command to start the test device to test the state of the detection line 115.

[0067] In one embodiment, the client is provided with a short-circuit test function module for the detection line 115 and an open-circuit test function module for the detection line 115. The function module is provided with a test interface, which includes the name of the serial port line to be tested, and also displays whether the line is tested. After starting the preset line state test command, according to the arrangement of the serial port lines preset in the test interface, the state of the line to be tested is tested in sequence.
