[Previous technology] In order to ensure the quality, in the quality control or acceptance process, the product needs to be tested for characteristics. In order to measure multiple objects to be tested at one time, the quality control acceptance process is shortened. Figure 丨 the electronic signal transmission device 2. The electronic signal transmission device 2 acts as a test instrument 丨 丨 The electronic signal transmission path between the object to be tested 12, 13, and 14 allows the test instrument to be sequentially connected to each of the objects to be tested 12, 13, 14 to sequentially test each DUT 12, 13, 14. The electronic signal transmission device 2 uses a circuit card as an example, and includes a controller 21, and the number of mechanical relays 22, 23, and 24 that can be driven by the controller 21 and the number of mechanical relays 22 and 23 , 24 have the same number of input terminals 25, 26, 27, and an output terminal 28. The circuit architecture of each mechanical relay 22, 23, 24 can be schematically illustrated as having an inductor 22 丨, 23 丨, and a switch 222, 232, 242. One end of each inductor 221, 231, 241 is connected to the control state 21, and the other One end is grounded, and one of the switches 222, 232, and 242 is connected to the output terminal 28 in white, and the other end is connected to the corresponding input terminal 25, 26 > 27 ° To test, first connect the test instrument 11 to the output Terminal 28, and lead the test objects 12, 13, and 14 to the input terminals 25, 26, and 27, respectively. During the test, the 'controller 21 will sequentially control the opening of relays 22, 23, 24 200540439 5 off 222, 232, 242 for a period of time, mechanical relays 22, 23, 24, one by one, M' Measure the control of each test object 12, 13 and the number transmission device 2. The test instrument jj measures most test objects 12, 13, 14. In addition, the number of 24 can be adjusted as needed, and currently can measure 128 DUTs. 10 Furthermore, in conjunction with Figure 2, taking mechanical relay 22 as an example, when the controller wants to control the single-mechanical relay 22 to open, it will first output the high level component in the drive signal to the inductor 221, so that the inductor 221 is excited to drive the switch. It seems to be turned on and short-circuited; after the measurement is completed, a low level drive signal of A 202 is output to the inductor 221, so that the inductor 221 is no longer excited and the switch 222 is turned off (referring to an open circuit). Since the inductor 221 has a -constant reactance, it is high-level component 201. At the beginning of the excitation signal, it will not immediately change the state of the switch 222, and 15 allows the test instrument 11 to be connected to each DUT 12, 13 14 through corresponding leads. Of characteristics. By means of electronic communication, 22, 23, and 128 mechanical relays can be measured in a more efficient manner, that is, a single amount of buffering will have an impact on „222's cyan plate and lead to the switch 222 ’s reed Yan moves for a period of time before it becomes stable. Generally, the operation time of the aforementioned switch 222 is referred to as the startup time Tm. Then, the driving signal of the high-level component 201 is continuously used to keep the already stable switch 22 on for a period of time, which is called stable The time τ2 enables the test instrument 11 to measure using the stabilization time I. Therefore, the general drive signal south level component 201 time will be equal to the startup time plus the stabilization time L. After the stabilization time I for measurement ends, the drive signal becomes The low level is divided into 202, and the magnetic inductance 221 is no longer excited, so that the switch 222 is restored to close. Similarly, at the beginning of the driving signal becoming low level component 201, the state of opening 20 200540439 5 10 15 == will not be changed immediately. At this time, the opening of the || 222 will still affect the Dand of the switch 222 after entering the + who will enter the + to make the ear piece 222 tremble for a period of time _ generally will drive the low level of the drive signal 2〇ι knife open The time from when the switch 222 stabilizes to close is called the release time I. At present, the controller 21 sets the high and low level components of the driver 20 to 20%, and will set the startup time til, the stabilization time τ2, and the release time. Τ3 27 reduces measurement time. However, with the aging or damage of mechanical relays and η relays, the start-up time will be delayed, and even mechanical: electricity: ~ 3, 24 can not be turned on normally, so that the stabilization time D2 is shortened to the cry of the instrument] to Discontinued and completely blocked the transmission of electronic signals, leading to the misjudgment of test object 12, 13, and 14 in test 1. Therefore, whether the mechanical relays 3 and 24 are normal is of great importance to the correct measurement of the test system. : In order to avoid the influence caused by the aging or damage of the mechanical relays 22, 23, and 24. «Transmission device 2 works normally, and the relays 22, 23, and 24 are eliminated in batches after the reliable life time recommended by the component manufacturer. .

According to the manufacturer's suggestion, “let the electronic signal transmission device 2 be replaced in batches when it is used up to one million times” may waste most of the relays that are still in normal operation, causing serious resource frustration and greatly increasing the test cost.

In the invention, the electronic signal transmission device with a fault detection function of the present invention is used to separately One of the plurality of objects to be tested is connected to a test instrument, and the power The sub-signal transmission device includes a plurality of input terminals, an output terminal, and a plurality of: 15 mechanical relays, a-controller, and a fault detection module. Each of the input terminals is suitable for connecting to the waiting test object. Corresponding one; the output terminal is suitable to be connected to the test instrument; the number of each mechanical relay is consistent with the number of the input terminals, and the mechanical relays are connected in series: corresponding to the input terminals such as Hai Between the person and the input terminal, each of the mechanical relays cries when they are enabled by a forest platform t jealous w 4 丄 口 0 ^ W This situation is switched to a consistent state of energy, when each of the mechanical 鏖 ^ When in the disabled state, the corresponding input terminal is not connected to the input terminal. When each of the mechanical relays is in the enabled state, the pair: the input terminal is connected to the output terminal; the -control Timely enable the machinery: one of the relays is in the enabled state, and the fault control module is used to sense whether the mechanical relays that are enabled in the mechanical relays such as 200540439 are working normally and the sensing is detected. Enable a mechanical signal when the mechanical relay does not work normally ° 5 The function of the present invention can provide an electronic signal transmission device with a fault detection function to detect whether each mechanical relay works normally by using a fault detection module, so that when it is detected that the work is not working properly Generate a warning signal to inform the user of the occurrence of abnormality in real time, and the effect of ## is to extend the life of the product and reduce the test cost. [Embodiment Mode] 10 The foregoing and other technical contents, features, and effects of the present invention are described in The following is a detailed description of the detailed description of the fourth preferred embodiment with reference to the drawings. Α In view of the fact that the electronic signal transmission device has no way of knowing the state of its parts, it takes 15 to replace the entire batch after the reliable number of users has caused the test cost. The electronic signal transmission device with fault function in the present invention is to add a fault accumulation test module to the electronic signal transmission device to obtain the status of the part and output a warning signal when an abnormal state is detected. Immediately inform users to solve problems. 20 配 图 Figure 4, the preferred embodiment of the electronic signal transmission device 4 with faulty debt testing function of the present invention is applied to a test system, so that a plurality of test objects 31 32, 33 can be connected to the test instrument respectively 3〇. The signal transmission device 4 of this embodiment includes a plurality of input terminals 4m, 42, 43, and 44, and a plurality of input terminals 41 and 42, corresponding to the mechanical type 45, 46, 47, and _ flute # ... ^ Brother I system 48 and a fault detection module 5. It is 8 5 10 15 200540439 ^ See, the electronic signal transmission of this example is 4 sets to measure 3 2 cases. The number of input terminals and mechanical relays is also the same, and those who are familiar with the art should know that it can be measured. The number of objects to be measured can be adjusted according to the design requirements, and the number of input terminals and mechanical relays can be adjusted correspondingly. Each of the input terminals 41, 42, 43 is separately connected for the object under test. The output 44 is for the test instrument to be connected. The circuit of each mechanical relay 45, 46, 47 can be illustrated as having a sense 451, 461, 471 and a switch 452, bias, W. Each of the inductor states, such as 47i series, is connected to the _ controller 48 and the other end is grounded to be driven by the first controller 48 to be excited. Each of the switches 452, 462, and 472 is a switch of a normal door, and refers to an open (or open) switch. Each open: 452, 462, and 472 are connected in parallel with the corresponding inductors 45i, 46i, and 471, and are connected at one end through an output line 49 to the output terminal 44, and the other-terminals are respectively connected to the corresponding input terminals 41, 42, 43. Therefore, the mechanical relays 45, 46, and 47 of the second weekday inch (when the first fork controller 48 is enabled) are disabled (e). The mechanical relays 45, 46, and 47 are connected in series to the corresponding input terminal ^^ and output terminal ^. There is an open circuit between each of the input terminal 、, 43 and the output terminal 44. When the test is started, the controller 48 sequentially outputs drive signals to the inductances 451, 461, and 471 of each of the mechanical relays 45, 46, and 47 to cause them to be excited and drive the corresponding switches 452, flutter 2 and π to close in sequence and short-circuit. The mechanical relays 45, 46, and 47 are switched from the disabled state to the enabled state one by one, so that the object to be tested 3, 32, and 33 connected to the corresponding input terminals 41, 42, 43 can pass the corresponding mechanical relay 45. , 46, 47, the output line 49 and the output terminal 44 are connected to the testing instrument 30 to perform the characteristic test of the object to be tested 20 200540439 31, 32, 33. Figure 6 In this example, the driving signal output from the controller 48 to each mechanical type can be included.-According to the standard of each mechanical relay 31, 32, 33 The high time of Fengcheng knife 481, and the level component 482 provided by the manufacturer with the release time ^; for example, each millisecond (Teng c). The low is different from the known electronic newsletter ^^ 查 、 苏 # $, ^ ~ Special delivery settings, the electronic signal transmission in this embodiment is provided with an extra dark # 、 B 丨 4 ^ ZZ Γ ^ text Fault detection branch group 5 to sense whether these mechanical relays 10, 45, 46, 47 work normally when enabled by the first controller 48, and when the enabled mechanical relays 45 or 46 are sensed < 〇 Generate a warning signal when it is not working normally. 15 Each mechanical relay 45, 46, 47 has a -standard characteristic change value when it changes between the disabled state and the enabled state. This standard characteristic change value includes a standard start time, standard release time, standard resistance value when the mechanical relay $ 45, 46, 47 is enabled, and so on. 20 The fault detection module 5 of this example includes a sensor 5 i and a processing unit 52 storing the standard characteristic change value. The sensor 51 senses a change in the characteristics of the enabled mechanical relay 45 or 46 or 47, and outputs a sensing signal correspondingly. The processing unit 52 is electrically connected to the first controller 48 and the sensor 51 to receive a sensing signal and compare it with a standard characteristic change value so as to output the warning signal when an abnormality occurs. The processing unit 52 in this example is a microprocessor. As mentioned before (Figure 2), when the mechanical relays 45, 46 and 47 are switched between the disabled state and the enabled state, the resistance value R will change, and the current value J and voltage value V will also change accordingly. (R = v / I). Therefore, the sensor 5 1 can select the quantity 10 200540439 to measure at least _ | of the resistance value, current value, and voltage value of the enabled mechanical relay Wu 1, the package state 45 or 46 or 47. In the present embodiment, the fault preparation test module 5 selects to monitor the current value of the enabled mechanical type, the electric appliance 45 $ 46 or 47, and a current sensor is connected in series to the output line 49. Allegro Mi⑽system's model A1321 Hall sensor 511 has an output bandwidth of 30KHZ. Familiar with this technique # 者 #I know that the sensor of this example can also use other types of current sensors, such as capacitive sensors, inductive sensors, etc., and should not be limited to this embodiment Exposed. When current flows through, for example, output line 49, magnetic% is generated around the line, and Hall sensor 511 senses the output of the electromotive force driven by the magnetic field as a sensing signal. In this example, in order to strengthen the magnetic field strength, as shown in FIG. 5, the output line 49 is wound around a plurality of turns (such as 100 turns) on a Gapped Toroid 50 with a slotted 501 to amplify the magnetic field, and The Hall sensor 511 is placed in the slot 501 to sense a magnetic field. For example, suppose the output line 49 is wound around 100 circles on the ring and the current flowing through the output line 49 is 10 microamperes (mA). According to the formula provided by the manufacturer, the magnetic field B of the female ampere is equal to the number of coils n times 6.9 Gauss. / A (B = N * 6.9gauSS / A), so the magnetic field strength is 6 9 Gauss (100 * 6 9 gauss / A * 0.01 A = 6.9 gauss). According to the original product specifications, the sensitivity of the Hall sensor 511 is 5mV / Gauss, so the output voltage of the Hall sensor 511 is 34.5mV (5mV / Gauss * 6.9gauss = 34.5mV). Therefore, as the current value changes, the Hall sensor 511 can correspond to the output voltage that increases as the current value becomes larger as a sensing signal. ίο 15 20 Since the Hall sensor 511 in this example is an analog Hall sensor and the output signal is weak, it needs to additionally include an amplifier 512 connected to one of the Hall sensors 5 μm to receive the sensing signal and Amplify it; and connect it to the amplifier-analog-to-digital converter 513 to receive the amplified sensing signal ^ and digitize it to output to the processing unit 52. However, those skilled in the art know this, Digital Hall sensors can also be applied directly, such as Micr_s 200540439. In detail, as shown in Figure 6, when mechanical relays 45, 46, and 47 are not enabled, switches 452, 462, and 472 are open, and the resistance value is unlimited. Large, the current of the input line 49 is 0. When the first controller outputs the driving signal to enable the mechanical relays 45, 46, and 47, the high level of the driving signal is as high as the initial output for a period of time, and the switch 452 or the command or 472 is still not affected temporarily. The output line 49 also has no current; then the switch 452 < 4 «472 is received; when the inductance or 461 or 471 is excited and the face is moved, the value of the output line 49 will suddenly increase and decrease; after a period of time, the switch 452 gradually Stable conduction to the contact (referring to a short circuit), so that the current value on the output line 49 maintains the preset value A]; and the current value is maintained at the preset value within the stabilization time T! 2. Then drive the low-level component of the signal 482 to output, open M 452 also temporarily maintain the enabled state, and then start to vibrate, then resume the disabled state, so that the current value on the output line 49 returns to 0 β as the output line 49 As the current changes, the electric value of the sensor 511 also changes equivalently. The hall sensor of the company's factory model HAL810 directly integrates analog hall sensors, amplifiers and analog to digital sensors, and can directly output digital signals that can be processed by the processing unit 52. In this example, the processing unit 52 stores the mechanical relay 45, 46, 47 12 5 10 15 20 200540439. The quasi-start time is generally set between the start time τη and the start time plus one, and the value of the stabilization time & . In addition, the processing order ★ 52 is connected to the controller and 48 on the one hand, and also connected to the sensing g 51 to receive its output: In this example, the processing unit 52 is further connected to the lines of the inductors 451, 461, and 471 of different mechanical types _45, 46, and 47 with different pin positions. In this way, the processing of the early tl 52 can be fed from which pin of the driving signal to learn which mechanical relay 45, 46, 47 is enabled. In this way, when the first controller 48 outputs a driving signal to the machine to be enabled or the “electricity H 45 3 3 4 4 7” processing unit 52 can immediately know that the first controller starts driving the mechanical relay 45 or 46 or π. Yes, and start to calculate when the voltage value of the sensing signal fed from the sensor 51 can reach the preset voltage value corresponding to the preset value Al steadily, as: real ^ startup time T 丨]. K Guanji Then, the processing unit 52 compares the actual starting phase τ " with the standard starting date, and if it is greater than the standard starting time threshold, a warning signal is correspondingly rotated. In order to let the user know immediately that an abnormal situation occurs: For example, the electronic signal transmission device 4 further includes a warning light 53 connected to the processing unit 52: the warning light 53 is driven to emit light as a warning signal. Also in this embodiment, the early 52 can also use the driving signal and the sensing signal. To calculate the actual release time T13 of the enabled relay 45 or 46 or 47. In addition, although this embodiment compares the calculated actual start τ with the standard start time, those skilled in the art should know, Processing order 1 and 52 may also Count the actual start time μ refers to the start time.) Compare with the standard start time at any time to get the information of whether the real time being counted is faster than the standard start time. 13 200540439 The second action time has exceeded the standard start time, and an alert signal is generated earlier. In order to allow the test system to respond immediately, the processing unit 52 can also output 5 ... to at least one of the first controller 48 and the test instrument 30. In the example, the processing unit 52 outputs the warning signal to the test instrument in real time. 30 and the first controller 48, so that the abnormal situation is immediately known. Yiyi 30 and the first-controller are both available. 10 As described above, in this embodiment, the fault detection module 5 is used to monitor each machine, and the relay is relayed. The actual start of it when it is started. Is Tn not greater than the standard k. Therefore, when the mechanical relay cannot be converted to the enabled state due to aging or damage, the fault detection module does not fail. gp 拄 止 A ^ ^ θ 奵 应Alarm signal generating appliances: 5: 4 6 = Measurement: Under the condition of production capacity, provide mechanical relay ^ 4 normal or abnormal information to avoid the situation of misjudgement of the DUT due to the abnormality of the mechanical relay. 15 Repeatedly, since the fault detection module 5 can be used in this embodiment to accurately determine the actual start time I of the mechanical relays 45, 46, and 47, the expected high-level component or low-level component of the driving signal becomes / The length of the knife, 482, can be shorter than the original requirements. For example, the time of high 20 4: can be closer to the actual start time I and the standard start time can be set to ^ close to the actual start time τη, or the time to move the low level component can be close. The actual release time Ti3 'to speed up the test speed. Moreover, the current of output line 49 is also related to «H33. Even if the current of output line 49 is G, except for the mechanical relay 45, which is aging or damaged and cannot be caused normally. Can cause open circuit, 14 200540439 may be open circuit caused by abnormality of DUT 31, 32, 33, or poor contact between DUT 31, 32, 33 leading to input terminals 41, 42, 43 and so on . In order to correctly identify the actual reason, as shown in FIG. 7, in the second embodiment of the electronic signal transmission device 4 ′ of the present invention, the fault detection module 5 further includes a plurality of first switches 5 and 54 and a second switch 55. There are also three input terminals 41, 42, 43 and the first switch 54. Each of the first switches 54 is connected to the corresponding input terminals 41, 42, 43 with one end and grounded at the other end, and is normally disabled and not conductive, and can be changed from the disabled state to the enabled state by the processing unit 52. Enabled state, and the corresponding input terminals 41, 42, 43 are grounded. One end of the second open 10 off 55 is connected to the output 44, that is, to the output line 49, and the other is connected to the i power source. The second switch 55 is also normally disabled and not conductive, and can be enabled by the processing unit 52 to change from the disabled state to the enabled state, and the output terminal 44 is connected to the power source, so that the power source is fed into the output line 49. At the beginning of the test, the first switch 54 and the second switch 55 remain disabled 15, and the fault fairy can still determine whether the mechanical relay 6 47 is working normally from the sensing signal; when a mechanical relay (such as Mechanical relay, 45) may be abnormal, such as the actual start time τ " greater than the standard start time 'processing unit 52 controls the first switch 54 and the second on_55 connected to the mechanical relay 45 to become enabled and guide 2 〇 pass, a loop is formed; at the same time, the processing unit 52 notifies the first controller 48 to output the driving signal again. In this way, the output of the processing unit 52 by the sensor Η is still longer than the standard startup time. If yes, it should be mechanical relay 45 failure

The processing unit 52 outputs a second warning signal to inform the use of The person may lead to a message of poor connection or abnormality of the DUT 31. In conjunction with FIG. 8, the “fault detection unit 5” in the two yoke example electronic signal transmission devices 4 of the second and second brothers of the present invention is different from that of the first embodiment. The embodiment lies in that it further contains :: quasi-test object 56 And a plurality of third switches 57. The matching input terminal is 3 sets of 15 and the number of the third switches 57 is also three. The -end of each third switch 57 is connected to the corresponding input $ 41, 42, 43 , And the other-the end is usually connected to the corresponding objects 31, 32, 33, and can be controlled by the processing unit M to switch to the standard test object 5 6. So, when the test work started The three switches 57 are connected to the on-shore DUT 31, 32, and 33 'failure reading and testing module 5, and the self-sensing signal is still "= mechanical relay II 45, 46, 47 is ..." Workable: Once an abnormality is detected in a certain machine, if the actual start time τη is greater than the "start time", the processing unit 52 will drive the mechanical relay M to connect = 5 6 and process the early 5 2 chanting flute ». The first-controller 48 retransmits the driving signal to the mechanical relay. In the processing order, it is determined whether the mechanical relay 46 is positive 5 or not. The sensor signal of 1 is the first; if the machine is still different, it is determined that it is faulty and output-Brother-No. 1 '. Know the user mechanical relay # Therefore * Conversely, if the mechanical relay is normal this time, Then rule out: the problem of the failure of the mechanical 20 200540439 type relay 46, and research and judge whether it is an abnormality caused by the DUT 32 itself or the poor connection between the DUT 32 and the input point 42, so the processing unit 52 outputs A second warning signal to inform the user that the connection may be poor or the DUT 32 is abnormal. 5 Use the first and second switches 54, 55 or the third switch 57 and The design of the standard DUT 56 allows the fault detection module 5 ', 5 "to further analyze and accurately determine the cause of the abnormality when it detects an abnormality. Furthermore, although the processing unit 52 is implemented by a microprocessor in the foregoing embodiment, as shown in the embodiment of FIG. 9, the processing unit 52 may also be a program built in the -control II, and The output of the sensor 51 is directly connected to the second controller 48, to directly expand the function of the first controller 48. To sum up, in the electronic signal transmission device 4 4 4 of the present invention, the fault detection modules 5, 5, 5, 5 ,, 5, 5, and 15 are used for Hall sensing. Device 511 to detect the current change of the enabled mechanical relays 45 and 46 / let the processing units 52 and 52 immediately determine whether the mechanical relay 5 46 47 is normal, and immediately send an invitation when an abnormality is detected Signal to inform the user to reduce the probability of misjudgment of the test; and thus shorten the actual start time Tn and release time T3 to speed up the test process; and f and the second switch 54, 55 or the third switch 57 and the standard to be tested The 56th step analyzes the cause of the failure, so that the user is expected to be a mechanical relay d ^, or the failure caused by the object to be measured or the connection is bad. First, because the processing units 52 and 52, the warning signal will be immediately notified to the first controller 48, 48, the test instrument 30, the first controller 48, 48, and the test instrument 30 200540439 test instrument 30, which can eliminate the fault. Mechanical relays, and continue to use mechanical relays that can still operate normally until the faulty relay reaches a predetermined ratio, and then shut down to replace all those faulty; not only make full use of the effectiveness of each mechanical relay Life, reduce the cost of component replacement; can also significantly reduce the frequency of maintenance and replacement of relays, improve operating efficiency. However, the above are only the preferred embodiments of the present invention.
