Its practical, high-accuracy so that the overload limitation of car number is possibly realized；(2) on the basis of elevator load person's number is obtained, realize
Security monitoring, it is to avoid the generation of casualty accident.
Brief description of the drawings
Fig. 1 is the block diagram of apparatus of the present invention.
Embodiment
As shown in drawings, the microprocessor (chip microprocessor) of apparatus of the present invention is connected to special thing by I/O port
Contact level profile measurement module realizes profile measurement, and connecting FLASH memory by SPI interface stores critical data, passes through
I/O port is connected to realize man-machine interaction respectively with keyboard input module, audible alarm module；Connected respectively by serial ports tactile
Touch liquid crystal display, GPRS module to realize man-machine interaction and remote communicating function, connected by I/O port with control output module
Connect, realize the control that raising is forbidden.
Special object contact surface profile measurement module by matrix arrangement microsensor or detecting element and monolithic
Machine (MCU) electrical connection is formed, and its output end (namely single-chip microcomputer output) is connected with microprocessor input.
GPRS module, touch LCD display are communicated with microprocessor, and wherein GPRS module can believe detection
Number it is delivered to by wireless network on Internet, so as to realize real-time monitoring of the remote computer to elevator operation.
Keyboard input module is used to switch over and confirm during parameter calibration.
Special object contact surface profile measurement module by the microsensor (piezoelectric transducer) of matrix arrangement or
Detecting element (microswitch) obtains corresponding detection signal, when there is personnel to be pressed in thereon, the microsensor of matrix arrangement
(piezoelectric transducer) or detecting element (microswitch) with regard to a matrix signal similar to object contact surface shape can be formed,
Monitoring host computer carries out operational analysis further according to these matrix signals, draws current carrying number.
Special object contact surface profile measurement module is analyzed the various activation signals collected, special with reference to human body
Counting algorithm of the present invention of seeking peace is calculated, judged and compared, and FLASH memory is stored data into time, in case adjust later
With and inquiry, and result is output on touch LCD display, when the number of carrying exceedes threshold value, passes through audible alarm in time
Module is alarmed, and will realize protection by controlling output module to cut off corresponding motor loop if necessary.
Before whether carry out number overloads judgement, electricity is first obtained by special object contact surface profile measurement module detection
The characteristic parameter of the contact shape of car ground loading personnel in terraced car, calculates car real-time further according to the inventive method
