Abstract
A stage lifting mechanism safety control system comprises lifting table control equipment and a reminding device. A control unit starts a pressure sensing unit when receiving orders from a lifting order input unit. The pressure sensing unit senses pressure of an object on the pressure sensing unit, sends a first signal to the control unit when the pressure of the object is less than or equal to preset pressure value, and sends a second signal to the control unit when the pressure of the object is larger than the preset pressure value. The control unit sends starting signals to the reminding device through a wireless receiving and sending unit when receiving the second signal from the pressure sensing unit. The control unit controls a lifting mechanism instantly according to lifting control orders when receiving the first signal from the pressure sensing unit. The reminding device continuously sends reminding messages after receiving the starting signals from the wireless receiving and sending unit, and stops sending the reminding messages after sending the reminding messages and after preset reminding time.
Description
Technical field
The present invention relates to Stage Design field, more particularly, the present invention relates to a kind of stage lift structure safety control system.
Background technology
Stage is the space that actor performance provides in theater, and it can make the performance concentrating on performer of spectators and obtain desirable appreciation effect.Stage is made up of one or more platform usually, and what they had can be elevated.The type of stage has picture-frame stage, extended position stage, circular ring type stage and rotary-type stage.
Lifting platform is one of most widely used equipment in stage machinery equipments under stage, in professional theatre, dance drama institute, threatre, all be equipped with a large amount of various types of lifting platform, even in some threatre based on turntable, be also configured with lifting platform or the elevator of different size in cydariform turntable.In the well-known music hall in many worlds, be provided with the lifting platform for band, chorus or large-scale musical instrument.Some tests small theatre, in order to realize the change of stage form, has been covered with the lifting platform by modular design under whole platform.For Grand National Theatre, in theatre equipments under stage, just have lifting platform 45, in the cydariform turntable of drama field, be provided with two pieces of lifting platforms and tridecyne elevator, music hall platform has three pieces of lifting platforms and one piece of piano lifting platform.The design of certain experiment small theatre, then arrange 24 lifting platforms.
For the lifting platform on stage, there is various effect.Such as, the main lifting platform arranged at the main Performance Area of stage is mainly used to move fast shift the scenes.According to the needs of the story of a play or opera, lifting platform can produce some unexpected atmosphere and effects.Lifting platform can also be utilized as the instrument storing performance platform blanket, stage props made from cloth, pliable plastic, or other soft materials sheet etc.
But, along with stage lift structure universal of such as lifting platform or lift and so on, along with the security incident produced also can not be ignored.
Such as, if lifting platform drops to below stage surface, so the position of lifting platform can form cavity or passage, if the host on stage or deduction personnel do not note cavity of entering into, then can fall down cavity and injured.Again such as, if the host on stage or deduction personnel are just standing in the region of lifting platform and stage ground, and now lifting platform declines suddenly or rises, then the host on stage or deduction personnel may fall down injured.
Therefore, it is desirable to provide a kind of technical scheme that can improve the security of stage lift structure.
Summary of the invention
Technical problem to be solved by this invention is for there is above-mentioned defect in prior art, provides a kind of stage lift structure safety control system that can improve the security of stage lift structure.
According to the present invention, provide a kind of stage lift structure safety control system, it comprises: lifting platform control appliance; Wherein, described lifting platform control appliance comprises: control unit, elevating mechanism and lifting instruction input unit; Wherein, the lifting instruction of input for inputting lifting instruction, and is passed to described control unit by described lifting instruction input unit; Described control unit is used for controlling described elevating mechanism when receiving described lifting instruction from described lifting instruction input unit according to the described lifting instruction received.
Preferably, described stage lift structure safety control system also comprises: alarm set; And described lifting platform control appliance also comprises: that be arranged in stage ground with pressure sensing cells that the is neighboring region in lifting platform region and wireless transmit/receive units; Described wireless transmit/receive units and described alarm set carry out radio communication; Described control unit is used for starting described pressure sensing cells when receiving described lifting instruction from described lifting instruction input unit; Described pressure sensing cells senses the pressure of the object on it when starting, and send the first signal when object pressure is less than or equal to scheduled pressure value to described control unit, send secondary signal when object pressure is greater than scheduled pressure value to described control unit; Described pressure sensing cells is automatically closed after sending the first signal to described control unit; Described control unit sends enabling signal by described wireless transmit/receive units to described alarm set when receiving secondary signal from described pressure sensing cells; Described control unit when receiving the first signal from described pressure sensing cells, and controls described elevating mechanism according to elevating control instruction at once; Described alarm set, after receiving enabling signal from wireless transmit/receive units, sends prompting message constantly, and stops sending prompting message after sending prompting message after predetermined reminder time; Wherein, described prompting message is one or more in passage of scintillation light, buzzer and vibration.Preferably, described first scheduled time is ten five seconds or other appropriate time.
Preferably, described predetermined reminder time is ten five seconds or other appropriate time.
According in stage lift structure safety control system, before the lifting signal inputted according to user at control unit controls the lifting of elevating mechanism, first can have when people at station, lifting platform edge and send enabling signal to alarm set, make alarm set send alerting signal in the given time in advance in the lifting of elevating mechanism, the host or the deduction personnel that carry alarm set like this can know that elevating mechanism is about to be elevated; Like this, host or deduction personnel can avoid standing in the position that lifting platform and stage fixed bottom boundary join, and the follow-up conscious cavity avoiding the lifting platform falling into decline to be formed, thus improve the security of host or deduction personnel.And sending the first signal to described control unit with before representing lifting platform edge there has not been people at station at pressure sensing cells, control unit makes elevating mechanism not carry out elevating movement, thus effectively prevent the generation of security incident.
