Example one
As shown in fig. 1, which is only one embodiment of the present invention, the present invention provides a stage security alarm method, including the steps of:
s1: a height sensor and a signal transmitter are arranged on the lifting plate;
and a height sensor is arranged at the edge of the top of the lifting plate, the signal emitter is electrically connected with the height sensor, the height sensor is a Honeywell PPT/PPT-R sensor, and the height of the top of the corresponding lifting plate is converted by measuring the included angle between the sliding arm and the datum line.
It should be noted that all install altitude sensor and signal transmitter around the lifter plate, every direction has a set of altitude sensor and signal transmitter at least in four directions, conveniently sends early warning signal to each different direction.
S2: the height sensor senses the height relative to the stage plane;
here, the height sensor is installed on the fixed stage plate, and the height count value of the height sensor are obtained at the same time, so as to obtain the height difference value of the height sensor sensing relative to the stage plane, if the height difference value of the height sensor sensing relative to the stage plane is positive, it indicates that the lifting plate is higher than the fixed plate and higher than the stage horizontal panel, otherwise, if the height difference value of the height sensor sensing relative to the stage plane is negative, it indicates that the lifting plate is lower than the fixed plate and lower than the stage horizontal panel.
S3: judging whether the height of the height sensor is higher than the plane height of the stage, if so, informing a signal transmitter to transmit a signal to a first preset range around the lifting plate; otherwise, executing step S4;
if the height sensor senses that the height difference value relative to the stage plane is a positive value, the lifting plate is higher than the fixed plate, the lifting plate is higher than the horizontal plane of the stage, a bulge is formed on the lifting plate on the stage at the moment, and a performer needs to step upwards if the performer does not find the rising lifting plate to possibly trip from the outer side of the lifting plate, otherwise, the performer needs to pay attention to the height difference if the performer does not find the rising lifting plate to possibly fall from the edge of the lifting plate from the inner side of the lifting plate. At this time, the notification signal emitter sends an early warning signal to a first preset range around the edge of the lifting plate.
Of course, the first predetermined range value is set before step S3 is executed.
S4: judging whether the height of the height sensor is lower than the level height of the stage, if so, informing a signal transmitter to transmit signals to a second preset range around the lifting plate; otherwise, executing step S3;
if the height difference value of the height sensor sensing relative to the stage plane is a negative value, the lifting plate is lower than the fixed plate, the lifting plate descends compared with the stage plane, a cavity is formed at the lifting plate on the stage at the moment, and a performer needs to be reminded of taking care of the cavity if the performer does not find that the descending lifting plate possibly falls down from the cavity from the outer side of the lifting plate. At this time, the notification signal emitter sends an early warning signal to a second preset range around the edge of the lifting plate.
Also before step S4 is performed, a second predetermined range value is set.
S5: the sole of the performer is provided with a signal receiver and an alarm, and the signal receiver receives the signal sent by the signal transmitter and informs the alarm to send out an alarm.

Only upon receiving the alarm signal from the signal transmitter in step S3 or step S4, step S5 is performed.
It should be noted that, in steps S3 and S4, if the height of the lift plate is greater than the height of the stage surface, the lift plate is directly determined to be raised in step S3, and the alarm notification of step S5 is executed; if the height of the lifting plate is smaller than the height of the stage surface, the step S3 is not executed, the step S4 is skipped to judge that the lifting plate descends, and the step S5 of alarm notification is executed; if the height of the lifting plate is equal to the height of the stage surface, which indicates that the lifting plate is not lifted temporarily, the steps S3 and S4 are executed in sequence and circularly until the height of the lifting plate is not equal to the height of the stage surface, the step S3 or the step S4 is executed correspondingly, and then the alarm notification of the step S5 is executed.
The stage safety alarm method is simple, convenient, intelligent and reasonable, intelligently judges the state of the lifting stage, timely sends out early warning signals to the periphery, and the shoe edge of a performer receives the early warning signals to inform the shoe body to send out an alarm so as to prevent the performer from falling off at the lifting stage in an abnormal state.
Example two

Or, in two determination modes of step S3 and step S4, the signal emitters respectively emit signals with different frequencies, and finally, in step S5, the oscillation frequency of the alarm is also different, so as to remind the performer to pay attention to the raised lifting plate or the depressed lifting plate.
Then, regarding the first predetermined range value and the second predetermined range value, if the lifting plate is lifted, the lifting height of the lifting plate is not high, the performer can conveniently identify the lifting plate, and the danger degree is not high even if the performer trips or falls down, otherwise, if the lifting plate is lowered, the bottom end of the lifting plate is generally a first floor, the lamplight is dim, the environment is complex, the falling danger degree is high, and an empty stage cavity is difficult to find, and more reaction time needs to be reserved, then the first predetermined range value should be smaller than the second predetermined range value, when the stage is lowered, the notification warning range is enlarged, the performer is reminded as soon as possible, and the safety degree is higher.
In addition, when step S5 is executed, signal receivers are arranged around the sole of the performer, and each signal receiver is connected with an alarm,
finally, when step S5 is executed, the signal receiver receives the signal from the signal transmitter, acquires the signal receiver closest to the signal transmitter, and notifies the alarm connected to the signal receiver to issue an alarm. When being convenient for like this send out the police dispatch newspaper, remind unusual lifter plate place direction, remind the performer to pay close attention to this direction, be careful dangerous.
