Description

Technical Field

[0001] The present invention relates to a timing device and method, and particularly to a timing device and method for measuring the switching action of a high-speed on-off switch. Background Art

[0002] A high-speed on-off switch is a device or equipment that can achieve on-off switching within an extremely short time (millisecond level and below). With its fast, stable, and reliable characteristics, it has been widely used in multiple industries such as aviation, aerospace, rail transit, power, metallurgy, and mining. The response speed and stability of the switch, especially the action time during its opening and closing processes, are key parameters for measuring the performance of the high-speed on-off switch. This parameter is of great significance for protecting electrical equipment, improving system stability, optimizing energy utilization, enhancing equipment performance, and meeting special requirements, etc.

[0003] However, currently, the measurement of the action time of the high-speed on-off switch mainly relies on a system built with relevant instrument tools such as oscilloscopes, signal generators, and multimeters. During the test, the oscilloscope is connected to the output end of the switch, and the signal generator is connected to the input end. By capturing the waveforms during the closing and opening processes of the switch with the oscilloscope, the action time of the switch is then analyzed and calculated. Since this timing method involves a relatively large number of standard instruments, the test preparation time is long, seriously affecting the test efficiency. Summary of the Invention

[0090] The timing counter executes the stop signal, stops and ends the timing;

[0091] 6) The acquisition time module calculates the time during the on-off switching action according to the number of clock pulses counted between the start and stop of the timing counter, and completes the timing of the high-speed on-off switch switching action.

[0092] In this embodiment, the specific signal processing process for measuring the switching action time of the high-speed on-off switch is as follows:

[0093] (1) Configure the "on" or "off" information:

[0094] Send an "on" or "off" instruction from the human-machine interface of the host computer to the program control information module in the time acquisition module, so as to complete the configuration of the "on" or "off" status information in the configuration information module; the configuration result is reflected by the indicator lights LED1 and LED2 of the status display module;

[0095] (2) Judge the consistency between the switch signal and the "on" or "off" status information:

[0096] After receiving the switch signal and the "on" or "off" status information, the specific logic operation logic of the logic judgment module is as follows:

[0097] After the program control information module receives the "on" status information, the program control information module outputs a high-level signal , and after the configuration information module receives the signal, it judges as a high-level state and outputs a high-level signal . When the high-speed on-off switch is not operating, the switch output terminal access interface outputs a high-level signal through the isolation chip when the high-speed on-off switch is "on" . At this time, the signals and perform a XNOR logic operation, that is , is true. At this time, the XNOR gate logic circuit outputs a high-level signal . After the second level matching module of the status display module receives the high-level signal , it outputs a high level , thus lighting up the indicator light LED1, proving that the high-speed on-off switch is currently in the "on" state, that is, the switch signal is consistent with the "on" status information.

[0098] Similarly, when the high-speed on-off switch is not operating, the switch output terminal access interface outputs a low-level signal through the isolation chip when the high-speed on-off switch is "off" . At this time, the signals and perform a XNOR logic operation, that is , is false. At this time, the XNOR gate logic circuit outputs a low-level signal . After the second level matching module of the status display module receives the low-level signal , it outputs a low level , thus lighting up the indicator LED2, proving that the high-speed on-off switch is currently in the "off" state, that is, the switch signal is inconsistent with the "on" state information.

[0099] After the program control information module receives the "off" state information, the program control information module outputs a low-level signal , the configuration information module receives After the signal, it is judged as the low-level state and outputs a low-level signal , when the high-speed on-off switch does not act, the switch output terminal accesses the interface. When the high-speed on-off switch is "on", a high-level signal is output through the isolation chip , at this time the signal and Perform the XNOR logic operation, that is , is false, and at this time the XNOR gate logic circuit outputs a low-level signal , the second level matching module of the status display module receives the low-level signal Outputs a low level , thus lighting up the indicator LED2, proving that the high-speed on-off switch is currently in the "on" state, that is, the switch signal is inconsistent with the "off" state information.

[0100] Similarly, when the high-speed on-off switch does not act, the switch output terminal accesses the interface. When the high-speed on-off switch is "off", a low-level signal is output through the isolation chip , at this time the signal and Perform the XNOR logic operation, that is , is true, and at this time the XNOR gate logic circuit outputs a high-level signal , the second level matching module of the status display module receives the high-level signal Will output a high level Thus lighting up the indicator LED1, proving that the high-speed on-off switch is currently in the "off" state, that is, the switch signal is consistent with the "off" state information.

[0101] (3) When the "on" or "off" state (switch signal) of the measured high-speed on-off switch is consistent with the configured "on" or "off" state information, a pre-trigger signal is sent to the pre-trigger module through the program control information module of the human-computer interaction interface of the host computer, or a pre-trigger signal is sent to the pre-trigger module through the trigger switch on the MCU single-chip microcomputer;

[0102] The program control information module outputs a signal , the pre-trigger module receives the signal and generates a high level At this time, prepare for the upcoming switch action switching time test and wait for the arrival of the trigger signal; by designing a pre-trigger mechanism, it is possible to prevent the timing counter from starting due to external interference at the trigger signal input interface;

[0103] (4) The trigger signal of the high-speed on-off switch is matched by the first level matching module and then outputs a high level ; The output signal of the pre-trigger module is high level , and the signal output by the OR gate logic circuit is true, the three signals are ANDed by logic operation. , the result is true, the timing counter receives the signal If it is in true state, the timing counter will be started;

[0104] (5) When the high-speed on-off switch action is switched, the input interface of the switch output receives the change of the excitation signal. There are two types of changes in the excitation signal:

[0105] The first switch changes from "off" to "on", and the signal connected to the interface at the input end of the device switch will change from the original low level to a high level after passing through the isolation chip. This signal is recorded as , at this time the signal The low level signal output by the configuration information module After XOR logic operation, the signal is true, that is , the timing counter stops receiving the signal When the timer is in the true state, the timer counter stops running. At this time, the timer counter completes the timing work, and the signal And the high level signal output by the configuration information module After the exclusive OR logic operation, the signal is false, the indicator light of the status display module switches from indicator light LED1 to indicator light LED2;

[0106] The second is that the switch changes from "on" to "off". The signal connected to the interface at the input end of the device switch will change from the original high level to a low level after passing through the isolation chip. This signal is recorded as , at this time the signal And the high level signal output by the configuration information module After XOR logic operation, the signal is true, that is , the timing counter stops receiving the signal When the timer is in the true state, the timer counter stops running. At this time, the timer counter completes the timing work, and the signal And the high level signal output by the configuration information module The signal becomes false after the XNOR logical operation and the indicator light of the status display module switches from indicator light LED1 to indicator light LED2;

[0107] Both steps (4) and (5) are for controlling the timer counter. Currently, the timer counter clocks of ordinary MCU single-chip microcomputers have reached the hundreds of megahertz level, and the test accuracy can reach 100 nanoseconds. Moreover, the timer counter clocks of some high-end MCU single-chip microcomputers can reach the gigahertz level, and the test accuracy of this method can reach the nanosecond level;

[0108] (6) The test time value is sent to the human-machine interface of the host computer through the program control information module:

[0109] The acquisition time module calculates the time during the on-off switching action based on the number of clock pulses counted between the start and stop of the timer counter, stores the time during the on-off switching action in a register, and transmits it through the bus to the program control information module. The program control information module sends the time during the on-off switching action to the human-machine interface of the host computer for display through remote communication.

[0110] Embodiment 2

[0111] Compared with Embodiment 1, the difference in Embodiment 2 is that step 1) is: using the status switch connected to the MCU single-chip microcomputer as the input of the "on" or "off" instruction in the configuration information module, thereby completing the configuration of the "on" or "off" status information in the configuration information module.

[0112] As described above, the above are only the specific implementation manners of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
