Abstract

The utility model discloses an elevator display device based on an ELD technology. The device consists of a power supply module, an elevator signal acquisition module, a central control module and an output drive module and also comprises an ELD terminal display output module, wherein the elevator display acquisition module is connected with the output module through a central processor; the output drive module is connected with the ELD terminal display output module; and the power supply module is connected with the central control module. The elevator display device has the advantages of high brightness and high contrast. Even in an outdoor sightseeing elevator or under the irradiation of a burning sun, the display device can cause passengers at any positions to still clearly see the contents displayed on the display with the characteristic that the visual angle is more than 179 degrees and approximate to a plane, and the temperature property set in the device can cause the device to still normally stably work at the high temperature of 85 DEG C and at the low temperature of minus 40 DEG C.

Description

A kind of elevator display apparatus based on the ELD technology

Technical field

The utility model relates to a kind of telltale, particularly be a kind of high-end elevator display unit of using.

Background technology

Along with the Chinese society rapid economy development, the raising of people's living standard, real estate presents the situation of high speed development, elevator is as the vehicle of coming in and going out in the building, obtained using widely, and elevator is more and more to the intelligent direction development, so its additional function also seems particularly important.

Elevator generally adopts LED, LCD as the man-machine system display interface, still because there are many unfavorable factors in LED, LCD on present stage, technology was used at present: show dull such as LED, brightness is not high, only be applicable to application than low side, and LCD brightness is not high, contrast ratio be not too clear, the visual angle is wide inadequately, and the installation environment to self requires high, although along with the development of technology, existing LCD brightness increases, and still can not reach desirable display effect out of doors.The visual angle problem can cause the passenger more for a long time, and the passenger who is in the small angle scope can't normally see content shown on the telltale clearly; And contrast ratio and brightness problem can cause out of doors occasion such as Sightseeing Lift normally to use; Because Sightseeing Lift directly is subjected to the irradiation of sunlight, and LCD is exposed to the sun under burning sun, high temperature can influence its result of use and service life in addition.

The utility model content

The utility model has overcome that above-mentioned brightness is not high, angular field of view is little and shortcoming such as contrast ratio is low, and a kind of high brightness, high-contrast are provided, and picture clearly is presented on high-resolution ELD elevator display unit in face of the passenger who is in any position.

To achieve these goals, the utility model is to realize by the following technical solutions:

A kind of elevator display apparatus based on the ELD technology, it is made up of power module, elevator signal acquisition module, Central Control Module (CCM), output driver module, and it comprises that also an EL terminal shows output module,

Described elevator signal acquisition module joins by central process unit and output module;

Described output driver module and ELD terminal show that output module joins;

Described power module and Central Control Module (CCM) join;

The utlity model has the advantage of high brightness, high-contrast, even Sightseeing Lift even under the irradiation of burning sun out of doors, also have visual angle characteristic greater than 179 ° of intimate planes, make the passenger be in any position can clearly see content shown on the telltale, its inner temperature performance that is provided with makes its normal and stable operation still under the condition of 85 ° of high temperature and-40 ° of low temperature.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is each module map of the utility model.

Fig. 2 is the utility model power module scheme drawing.

Fig. 3 is each module connection diagram of the utility model.

Fig. 4 is the whole block diagram that connects of the utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.

With reference to shown in Figure 1:

A kind of elevator display apparatus based on the ELD technology, it is made up of power module, elevator signal acquisition module, Central Control Module (CCM), output driver module, it comprises that also an ELD terminal shows output module, and the elevator signal acquisition module joins by central process unit and output module; Output driver module and ELD terminal show that output module joins; Described power module and Central Control Module (CCM) join.As shown in Figure 2, power module provides energy output for whole ELD elevator display unit, it is converted into the 12V direct current (DC) with the 220V alternating current by a voltage transformer earlier, and then be separately converted to the direct current (DC) of 5V and 3.3V by power module, used for whole elevator display unit, power module has adopted and the LM2575 of National company and LM1117 are converted into required DC 5V of system and DC 3.3V with the DC 12V of external switch power supply in the utility model.

With reference to figure 3, the elevator acquisition module is finished by the PIC16F578 8-digit microcontroller of MICROCHIP company, it is connected by serial communication mode by elevator control cabinet, finish real-time communication, gather the elevator real-time running state, the MB90F352 position Central Control Module (CCM) of Fuji Tsu's development will be sent to behind the data handing, central processing module is the core processing unit of whole ELD elevator display unit, it is by receiving the elevator real-time running data that transmits from the elevator signal acquisition module, make corresponding processing, be transferred to S1D13700 output driver module by EPSON company, after the output driver module receives the executive command of Central Control Module (CCM), executive command is translated into the discernible data of performance element show output module to drive the ELD terminal, the ELD terminal shows that output module adopts 5.7 cun EL of PLANAR company to shield as terminal display device, clearly is presented on the passenger who is in any one position in the elevator with outstanding display effect.

Fig. 4 is the whole block diagram that connects, power module provides energy source for the ELD elevator display unit, the elevator control cabinet bucket is crossed serial communication mode and is connected on the ELD elevator display unit, the utlity model has high brightness, the advantage of high-contrast, even Sightseeing Lift even under the irradiation of burning sun out of doors, also have visual angle characteristic greater than 179 ° of intimate planes, make the passenger be in any position still can clearly see content shown on the telltale, its inner intensity temperature performance that is provided with makes its normal and stable operation still under the condition of 85 ° of high temperature and-40 ° of low temperature.
