Referring to accompanying drawing 2, control circuit of the present invention comprises: microprocessor module is used for storage and executive control program; Serial interface module is used for converting differential signal to the fiduciary level signal; The power conversion module is used to telltale that power supply is provided; And the direction indicating module, be used to show the service direction of elevator; The floor display module is used to show elevator place floor; Fully loaded indicating module is used to show the overload indication of elevator; Urgent indicating module is used to show the emergency services indication of elevator; Wherein microprocessor module is with the power conversion module, serial interface module and application controls module couple together, external power supply outputs to the microprocessor module first input end through the power conversion module, link to each other with microprocessor second input end by serial interface module simultaneously, finish outward sign conversion and with the I/O of microprocessor module, the mouth of microprocessor module links to each other with direction indicating module, floor display module, fully loaded indicating module, urgent indicating module respectively, and then finishes various controls and demonstration to elevator.
Example 3 micro controller modules
Referring to accompanying drawing 3, microprocessor module comprises central processing unit, clock generator, program store, data memory and input/output interface.These submodules in the microprocessor module all are in order to finish storage and the executive control program that microprocessor itself will be finished, in this module, need to carry out following steps: on universal serial bus, search clock sync signal, make that to set up clock between telltale and the elevator main controller synchronous.Because except that telltale, also comprise other a plurality of remote controllers on the universal serial bus, so a plurality of remote controllers that are connected on the universal serial bus all have own unique address code.When set up between telltale and the elevator main controller clock synchronously after, just on universal serial bus, search address code corresponding, i.e. address synchronization with it according to the address code of telltale.After address synchronization had been set up, telltale began to read data from universal serial bus, i.e. data sync.After data sync was finished, the needed various data of telltale all were kept in the middle of the data memory by microprocessor module.Next, microprocessor module can output to data information stored on floor indicator and the various indicating device under the control of program.
The function of micro controller module: storage and executive control program comprise: receive from the elevator main controller
Command information changes elevator floor and indicated number.
Example 4 communication interface moduless
Referring to accompanying drawing 4, communication interface modules function: serial signal conversion.The bus differential signal is converted to the level signal of standard.
Example 5 power transfer module
Referring to accompanying drawing 5, power conversion functions of modules: for telltale provides power supply.The direct current 30V power supply of outside input through twice step-down, is transformed into the direct current 5V power supply of standard.
Example 6 direction indicating modules
Referring to accompanying drawing 6, direction indicating module function: show the service direction of elevator, and overload indication and emergency services indication etc.The high-brightness LED luminary is adopted in the indication of this module, has therefore used ULN2003 as actuator.
