Detailed Description
In order to enable those skilled in the art to better understand the present invention, the following description will make clear and complete descriptions of the technical solutions according to the embodiments of the present invention with reference to the accompanying drawings. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the invention. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
In use of a daily bluetooth input device, if the input device is already connected to the device 1, then the device 1 must first be operated to disconnect the input device from the device in order to disconnect the input device from the device 2, after which the input device can only be disconnected from the device 2, and if the user often switches between the device 1 and the device 2, frequent cross-disconnects of the device 1 and the device 2 are required, which is relatively inconvenient for the user and thus less experienced.
In order to solve the above problems, referring to fig. 1, on the one hand, an embodiment of the present invention provides a signal detection method of a multifunctional detector, capable of switching connection between a plurality of devices, including the steps of:
referring to fig. 1, 3 and 4, the present invention provides a signal detection method of a multifunctional detector, comprising the steps of:
s101, receiving a detection setting signal input by a user;
s102, controlling the output relay to isolate the detection signal of the output terminal element to the tested terminal element according to the detection setting signal;
s103, receiving a test feedback signal which is output by a tested terminal element and is input through an input relay in an isolated manner;
s104, judging whether the tested terminal element is abnormal according to the detection setting signal and the test feedback signal, and outputting a normal or abnormal prompt.
Specifically, as shown in fig. 4, before the tested element is tested, the output cable is connected to the test signal output end of the tester and the tested element, and is connected to the test signal output end of the tester and the tested element or the test bench through the input cable. Thus, the tester signal can be sent to the tested element and receive the feedback signal fed back. After the connection between the detector and the element under test is made by means of a cable. And the user outputs a corresponding detection setting signal through a human-computer interface. For example, on a man-machine interface, the number of loops of the detection terminal is set, the cycle time of each loop is detected, the type of the detected element is the default NPN type, and the PNP type needs to be selected on the interface. In this way, the detection parameters can be set. After the user sets the detection parameters, the detection setting signals input by the user are received and saved in step S101. The user selects the detected terminal element, correctly places the terminal element on the detection frame, and firmly inserts the OUT and the MIL terminal of the IN. The start key of the operation box is pressed, the PLC input end receives an operation instruction, and the operation program starts. Step S102, according to the detection setting signal, controlling the output relay to isolate the detection signal of the output terminal element to the tested terminal element;
during testing, a test signal is output to the output relay through the PLC, and the test signal is output to the terminal test board or the tested element terminal after signal isolation through the output relay. Therefore, the isolation of signals between the PLC controller and the terminal test board or the tested element terminal can be realized, and the interference of an external power supply or signals to the PLC controller or the burnout of the PLC controller is avoided. For example, when a power supply signal of a device under test terminal is short-circuited, a large current is easily generated, and the controller of the device under test terminal is easily burned out by the large current, and the controller is easily burned out by acquiring a surge signal. After the output relay circuit is used for isolation, the large current or surge signal generated by the short circuit of the power signal of the tested element terminal can not influence the PLC controller, so that the PLC controller can be protected. After outputting the test signal to the element terminal to be tested, a feedback signal of the element terminal needs to be received. In step S103, receiving a test feedback signal outputted from a tested terminal element and isolated from an input via an input relay; the terminal test bench or the tested element terminal feedback signal can be isolated from the PLC controller and input to the PLC controller through the input relay circuit similarly to the output signal. Avoiding the interference of external power supply or signal to the PLC controller or burning the PLC controller. After receiving the feedback signal of the isolation input, the PLC controller can perform fault detection on the tested piece according to the feedback signal. The signal or power supply is isolated between the measuring part and the PLC controller through the relay for input and output. Therefore, the large current generated by the power supply of the tested piece can not affect the PLC controller, so that the power supply of the tested piece can be tested through the PLC controller, and signals can not be tested only. When the active terminal is detected, a 24V power supply and an NPN or PNP signal are received at the receiving power side, and when one of the detected terminals is detected without a signal, the program calculates according to the sequence and the period of the detection process. When the passive terminal is detected, a power supply direct connection plug is arranged on the side of the receiving power supply, the signal connection end is also plugged in sequence, NPN or PNP signals are detected, the operation interface is determined through setting, and when one detected terminal has one signal-free detection, the program calculates according to the sequence and the period of the detection process. In step S104, it is determined whether the tested terminal element is abnormal according to the detection setting signal and the test feedback signal, and a normal or abnormal prompt is output. When the input of the detection signal is abnormal, the PLC calculates, displays the unqualified word on the operation screen, and can control the alarm lamp and the alarm to sound simultaneously through the output of the PLC so as to prompt an operator to treat unqualified terminals. When detecting that each power supply of the terminal is normal, each signal feedback is normal, a character prompt can be provided on an operation interface, and a normal warning and sounding sound is output. At this time, the inspector dials out the inspection connection wires in order from the terminals. The terminal is replaced with a new one, and the above steps are performed.
In the signal detection method of the multifunctional detector, step S101 is performed to receive a detection setting signal input by a user; s102, controlling the output relay to isolate the detection signal of the output terminal element to the tested terminal element according to the detection setting signal; s103, receiving a test feedback signal which is output by a tested terminal element and is input through an input relay in an isolated manner; s104, judging whether the tested terminal element is abnormal according to the detection setting signal and the test feedback signal, and outputting a normal or abnormal prompt. In this way, in the testing process of the tested element terminal, the input and output signals are isolated by controlling the relay, the large current generated by the power supply of the tested element can not influence the PLC controller, and the power supply, the signals and the like of the tested element can be tested by the PLC controller.
Further, in one embodiment of the present invention, the detection setting signal includes: and when the number of the test loops is multiple, respectively controlling the output relay to sequentially isolate and output the detection signals of all paths of terminal elements to the tested terminal elements, sequentially receiving the test feedback signals which are isolated and input by the input relay, respectively judging whether each path of test feedback signals is normal or abnormal, and sequentially outputting normal or abnormal prompts.
Specifically, when a plurality of loop signals need to be set, the output relay needs to be controlled to output each path of test signals in sequence, and when each path of signal output is normal, the signal is indicated to be in a normal state by the indicator lamp. Thus, the user can acquire the normal output state of each signal, and when the output signal is abnormal, the user can also indicate through the indicator lamp. Thus, when the feedback signal is detected, it is possible to determine whether the output signal is faulty or whether the element to be tested is faulty. The fault position of the tested element terminal can be positioned by sequentially receiving the test feedback signals which are isolated and input through the input relay, respectively judging the normal or abnormal state of each path of test feedback signals and sequentially outputting normal or abnormal prompts, so that a user can conveniently find the fault position of the tested element terminal.
Further, in an embodiment of the present invention, the detection setting signal further includes: the device comprises a detected element terminal type signal, wherein when the element terminal type is NPN type signal terminal, a test feedback signal which is isolated and input by an input relay is received and is a normal signal when the test feedback signal is an in-phase signal; when the element terminal type is PNP type signal terminal, the test feedback signal which is isolated and input by the input relay is received as an inverted signal and is a normal signal; when the element terminal type is an active terminal, the control relay outputs one path of power supply in an isolated manner so as to supply power for each connecting terminal, and the test feedback signals received and input through the input relay are normal signals when all paths of power supply signals are in-phase signals.
Specifically, by setting the detected element terminal type signal, it is possible to realize fault detection for different types of detected element terminals. For example, an NPN-type signal terminal and a PNP-type signal terminal may be included. Because the output signals of the different types of terminals are different under the action of the test signals, the terminals can be set by the type signals of the tested element terminals in order to be compatible with various tested element terminals. Thus, in step S104, it is determined whether the tested terminal element is abnormal according to the detection setting signal and the test feedback signal, and a normal or abnormal prompt is output, so that signal determination errors can be avoided. Meanwhile, the device can be compatible with testing of terminals of different types of tested elements.
Further, in an embodiment of the present invention, the detection setting signal further includes: and the periodic time signals respectively control the output relay to sequentially isolate and output each path of terminal element detection signals to the tested terminal element in a set time period, sequentially receive test feedback signals which are isolated and input by the input relay in the set time period, respectively judge the normal or abnormal state of each path of test feedback signals, and sequentially output normal or abnormal prompts.
Specifically, the signal condition of each terminal can be effectively detected through the PLC program. The detection time and the detection mode required by each terminal are strictly operated according to the program, when each terminal is tested, the program outputs each path of test signal in a set time period and receives each path of feedback signal respectively, so that the test of one tested terminal can be completed in the set time period, and the test efficiency of the tested element terminal is ensured.
Referring to fig. 2, in one embodiment of the present invention, the method for detecting a signal of the multifunctional detector includes the steps of:
s201, receiving a detection setting signal input by a user;
s202, controlling the output relay to isolate the detection signal of the output terminal element to the tested terminal element according to the detection setting signal;
s203, receiving a test feedback signal which is output by a tested terminal element and is input through an input relay in an isolated manner;
s204, judging whether the tested terminal element is abnormal according to the detection setting signal and the test feedback signal, and outputting a normal or abnormal prompt.
S205, when the test feedback signals of a plurality of continuous time periods are in abnormal states, judging whether the test feedback signals of all paths are identical in sequence;
s206, stopping normal or abnormal prompt if the test feedback signals of each of the multiple continuous time periods are the same;
s207, stopping controlling the output relay to isolate the detection signal of the output terminal element and entering a standby state when all paths of test feedback signals exceeding a set continuous time period are the same;
specifically, in this embodiment, steps S201 to S204 are the same as those of the previous embodiment, and the detailed description is not repeated here. After receiving the feedback signals of the respective paths input through the input relay. In step S205, when the test feedback signals of multiple continuous time periods are all in an abnormal state, determining whether each path of test feedback signals are the same in sequence; the situation that the test element terminal is not replaced or the test bench is not provided with the element terminal may occur, at this moment, in a plurality of test period time, the feedback signals are all fault signals, through S206, if the test feedback signals of each path of the plurality of continuous time periods are all the same, normal or abnormal prompt is stopped, the test bench is not replaced with a new test terminal, no test terminal is installed on the test bench is obtained, and thus, in each test period, the test feedback signals of each path are the same and are all abnormal feedback signals, and at this moment, abnormal signal alarm can be stopped. In step S207, when the test feedback signals of each path exceeding the set continuous time period are the same, the control output relay is stopped to isolate the detection signal of the output terminal element, and the standby state is entered; since the user is not connected to a new component under test terminal through the test station. At this time, a standby state can be performed, thereby saving electric energy and ensuring the service life of the detecting instrument.
