Referring to fig. 1, a flow chart of a safety control method based on electromagnetic emission according to an embodiment of the invention is shown. The safety control method based on electromagnetic emission depicted in fig. 1 comprises the following steps:
s1, receiving an electromagnetic circuit detection instruction, and performing electromagnetic circuit detection on a pre-built initial electromagnetic emission device according to the electromagnetic circuit detection instruction to obtain an electromagnetic circuit detection signal, wherein the initial electromagnetic emission device comprises: the device comprises a transmitting tube, a magnet, an armature, a power supply, a control circuit, a cooling device, a sensing device and a feedback device.
It can be understood that the electromagnetic circuit detection instruction refers to an instruction sent by a user and used for detecting whether the control circuit is a normal connection circuit, and when the control circuit has short circuit, open circuit and other phenomena, the normal electromagnetic emission is affected. And the electromagnetic circuit detection signal value carries out circuit constant voltage detection and circuit constant current detection on the control circuit to obtain a constant voltage resistance change curve and a constant current resistance change curve. Therefore, the normal performance of the control circuit can be further judged according to the detected constant voltage resistance change curve and the detected constant current resistance change curve.
In the embodiment of the present invention, the electromagnetic circuit detection is performed on the pre-built initial electromagnetic emission device according to the electromagnetic circuit detection instruction to obtain an electromagnetic circuit detection signal, including:
identifying a power supply positive circuit end and a power supply negative circuit end of the initial electromagnetic emission device;
according to the power supply positive circuit end, the power supply negative circuit end and the preset detection duration, performing circuit constant voltage detection and circuit constant current detection on a control circuit of the initial electromagnetic emission device to obtain an electromagnetic line current change curve and an electromagnetic line voltage change curve;
calculating a constant voltage resistance change curve according to a preset constant voltage value and the electromagnetic line current change curve, and calculating a constant current resistance change curve according to a preset constant current value and the electromagnetic line voltage change curve;
and summarizing the constant voltage resistance change curve and the constant current resistance change curve to obtain the electromagnetic line detection signal.
Further, the positive power supply circuit end and the negative power supply circuit end refer to a circuit end of the control circuit connected with the positive power supply and a circuit end connected with the negative power supply. The detection duration may be determined according to actual needs, for example: and 1 hour.
It can be understood that the circuit constant voltage detection and the circuit constant current detection respectively refer to a current variation test performed on the control circuit by using a preset constant voltage and a voltage variation test performed on the control circuit by using a preset constant current. The constant voltage value refers to the voltage of the constant voltage detection of the circuit, and the constant current value refers to the current of the constant current detection of the circuit.
In detail, the constant voltage resistance change curve and the constant current resistance change curve refer to change curves of line resistance when circuit constant voltage detection and circuit constant current detection are performed.
S2, judging whether the electromagnetic line detection signal is normal or not.
In the embodiment of the present invention, the determining whether the electromagnetic line detection signal is normal includes:
acquiring a circuit normal temperature resistance value of the control circuit;
calculating the constant voltage resistance change curve and the dynamic resistance integral error of the constant current resistance change curve according to the normal temperature resistance value of the circuit by utilizing a pre-constructed error integral formula;
judging whether the dynamic resistance integral error is larger than a preset error threshold value or not;
if the dynamic resistance integral error is larger than the error threshold, the electromagnetic line detection signal is abnormal;
and if the dynamic resistance integral error is not greater than the error threshold, the electromagnetic line detection signal is normal.
The circuit normal temperature resistance value refers to the circuit resistance of the control circuit at normal temperature.
In detail, the error integration formula is as follows:
wherein μ represents a dynamic resistance integration error, t 1 The initial detection time t of the constant voltage resistance change curve or the constant current resistance change curve is represented 2 The termination detection time of the constant voltage resistance change curve or the constant current resistance change curve is represented, k (t) represents a resistance time weight function, r u Representing the change value of the resistance with time, i in the constant voltage resistance change curve c The change value of the resistance with time in the constant current resistance change curve is shown, and t is time.
It can be appreciated that the control circuit needs to maintain the line resistance in a certain fluctuation range under different currents and different voltages, so as to improve the safety of electromagnetic emission. Therefore, the control circuit can be used for circuit constant voltage detection and circuit constant current detection, so that a corresponding constant voltage resistance change curve and a corresponding constant current resistance change curve are obtained. And if the errors of the constant voltage resistance change curve and the constant current resistance change curve are kept within the error threshold range, the control circuit is qualified.
It can be understood that the calculating the dynamic resistance integration errors of the constant voltage resistance change curve and the constant current resistance change curve according to the normal temperature resistance value of the circuit by using the pre-constructed error integration formula includes:
identifying a constant voltage starting resistor and a constant current starting resistor of the constant voltage resistance change curve and the constant current resistance change curve;
calculating a resistance time weight function according to the normal temperature resistance value, the constant voltage starting resistance and the constant current starting resistance of the circuit by utilizing a pre-constructed resistance time weight formula, wherein the resistance time weight formula is as follows:
wherein p represents a weight adjustment factor,represents the constant voltage starting resistance, ">Represents the constant current initial resistance, r 0 The normal temperature resistance value of the circuit is represented, and t represents time;
and calculating the dynamic resistance integral error by utilizing the error integral formula according to the resistance time weight function, the constant voltage resistance change curve and the dynamic resistance integral error of the constant current resistance change curve.
Further, since the temperature of the control circuit is raised during the constant voltage detection and the constant current detection of the circuit, the resistance calculation of the control circuit is affected, and the longer the power-on time is, the higher the temperature of the control circuit is, the weighted regulation and control of the dynamic resistance integral error are required by the resistance time weight function, and the temperature change effect caused by the extension of the test time is reduced. The constant voltage starting resistor and the constant current starting resistor refer to resistance values of starting points of the constant voltage resistance change curve and the constant current resistance change curve respectively. Since the current temperature may be greatly different from the normal temperature, a factor of the difference between the current temperature and the normal temperature needs to be added to the calculation of the resistance time weight function.
It can be understood that, when the testing time of the circuit constant voltage detection and the circuit constant current detection is longer, the difference between the current temperature and the normal temperature is higher, the smaller the corresponding resistance time function weight is, so that the influence of different temperatures on the electromagnetic line detection signal is relatively fixed. The quality evaluation calculation of the control circuit is more accurate.
And if the electromagnetic line detection signal is abnormal, executing S3, and prompting that the control circuit is abnormal.
And if the electromagnetic line detection signal is normal, executing S4, and debugging the installation position of the micro switch on the initial electromagnetic emission device to obtain the installation position of the micro switch.
It will be appreciated that the microswitch mounting position is related to the armature loading tip position so that the micro-air switch is depressed and closed by the armature.
In the embodiment of the present invention, the step of performing the adjustment of the installation position of the micro switch on the initial electromagnetic emission device to obtain the installation position of the micro switch includes:
setting an installation test position set of the micro switch;
sequentially extracting the installation test positions in the set of the installation test positions;
fixing the micro switch at the installation test position to obtain a micro switch test position;
filling the armature in a preset armature filling terminal position, and judging whether the micro switch is pressed by the armature and is in a closed state;
if the micro switch is not pressed by the armature and is in a closed state, returning to the step of sequentially extracting the installation test positions in the set of the installation test positions;
and if the micro switch is pressed by the armature and is in a closed state, taking the micro switch testing position as the micro switch mounting position.
It can be understood that the installation test position set refers to a plurality of preset installation positions near the filling end position of the armature, and the position of the micro switch needs to be continuously adjusted because the micro switch needs to be pressed and closed by the armature, and finally a proper installation position of the micro switch is found.
And S5, installing the pre-built micro switch at the installation position of the micro switch to obtain the target electromagnetic emission device.
It can be appreciated that the mounting position of the micro switch can be shown with reference to fig. 3.
And S6, placing the micro switch in the target electromagnetic emission device in a closed state to obtain a control closed circuit.
It can be explained that it is necessary to test whether the micro-switch is functioning properly before electromagnetic emission is performed, so that it is necessary to close the test function.
S7, judging whether the control closed circuit is a passage or not.
In an embodiment of the present invention, referring to fig. 2, the determining whether the control closed circuit is a path includes:
s71, identifying a positive end and a negative end of a micro switch of the control closed circuit, and measuring whether the positive end and the negative end of the micro switch are passages or not;
s72, if the positive end of the micro switch and the negative end of the micro switch are the paths, the control closed circuit is the path;
and S73, if the positive end of the micro switch and the negative end of the micro switch are not the paths, the control closed circuit is not the paths.
It should be understood that the positive end of the micro switch and the negative end of the micro switch refer to the end of the micro switch connected with the positive electrode of the power supply and the end of the micro switch connected with the negative electrode respectively.
And if the control closed circuit is not a passage, executing S8, and prompting that the control closed circuit is abnormal.
And if the control closed circuit is a passage, executing S9, and placing the micro switch in an open state to obtain a control open circuit.
Further, the micro-control switch should have the armature pressed closed, so it needs to be opened before the armature is filled.
And S10, filling the armature at a preset armature filling end position, and pressing the micro switch in the control breaking circuit by using the armature to obtain a control pressing circuit.
It can be appreciated that the micro switch is pressed by the armature at the end position of the armature loading, so that the communication of the control circuit is realized, and a control pressing circuit is obtained, and the pressing of the micro switch by the control pressing circuit can be shown by referring to fig. 4.
In an embodiment of the present invention, the loading the armature at a preset armature loading end position includes:
filling the armature at the armature filling terminal to obtain an armature to be corrected;
judging whether the armature to be corrected can pass through the transmitting tube or not;
if the armature to be corrected cannot pass through the transmitting tube, carrying out position correction on the armature until the armature to be corrected passes through the transmitting tube;
if the armature to be corrected can pass through the transmitting tube, the armature is completely filled at the armature filling terminal position.
Further, in order to avoid the occurrence of the offset of the emitter tube, it is necessary to further ensure that the armature can pass through the emitter tube after ensuring that the armature is accurately mounted at the armature loading tip position. Thus requiring further correction of the armature.
Further, the determining whether the armature to be corrected can pass through the transmitting tube includes:
calculating the orifice deviation value of the armature to be corrected and the emitting tube;
if the orifice deviation value is 0, the armature to be corrected can pass through the emitting tube;
if the orifice deviation value is not 0, the armature to be corrected cannot pass through the emitting tube.
It is understood that the conduit deviation value refers to the ratio of the area of the deviation of the armature from the conduit inlet cross section to the conduit inlet cross section of the emitter conduit. The deviation area can be observed along the axial direction of the emission pipe to obtain the area of the armature outside the section of the emission pipe.
S11, receiving an electromagnetic emission instruction sent by a user according to the control pressing circuit, starting electromagnetic emission according to the electromagnetic emission instruction, and completing safety control based on the electromagnetic emission.
Further, the above-described safety control scheme, in which the armature is cylindrical, when the armature is spherical, also if the spherical armature is not fully loaded in place, if the fire button is pressed, it can also lead to unexpected firing results or even accidents. When the spherical armature is filled, the first step is to place the spherical armature at a preset filling position, and then install a ring magnet outside a transmitting tube on the cross section of the sphere center of the spherical armature so as to accurately fix and suspend the spherical armature at the preset filling position. The second step requires making a perpendicular to the axis of the emitter tube on the sphere center where the ball-type armature is located at the predetermined loading position, and then cutting two photoelements symmetrically on the left and right sides at two intersections of the perpendicular and the emitter tube wall, as shown in fig. 5.
