Embodiment
With reference to the accompanying drawings the utility model is done and is further described:
Referring to accompanying drawing 1, Fig. 2, Fig. 3 are applied to the parameter display board of lifting means; Mainly by display module, driver module and the signal input module three parts composition that is linked in sequence is characterized in that; Described display board also is provided with filtration module,, described filtration module is connected on the signal input module.
Resistance in series A and resistance B form described filtration module again by electric capacity A, electric capacity B parallel connection.
Electric capacity A is that 33 μ, electric capacity B are 0.1 μ in the described filtration module; Resistance A is 5.1 Ω, and resistance B is 10K.
After power filtering module receives the power supply of external switch power supply, through supplying power to the utility model after the filtration module filtering.
Filtering is exactly to reduce the fluctuation composition in the input voltage as much as possible, is transformed near permanent steady direct current and makes more smooth working of chip.The method of filtering adopts passive element electric capacity, utilizes it to voltage, and the energy storage characteristic of electric current reaches the purpose of filtering.Because capacity cell has the energy storage effect in circuit, when the voltage that the capacitor C of parallel connection supplies with at power supply raises, can store portion of energy, and when supply voltage reduces, discharge energy, make load voltage level and smooth.
Referring to accompanying drawing 2, Fig. 4, described display module comprises two groups, and every group is made up of five eight sections charactrons, and each charactron works independently, and each shows of numerical value.
Described five eight sections charactrons are selected LG8012BH positive charactron altogether; The anode of described five eight sections charactrons connects together and links to each other with the positive source of filtration module output; Each section that the negative electrode of described five eight sections charactrons is corresponding is used for linking to each other with coding chip, and each eight sections charactrons are controlled respectively by coding chip.
When the negative electrode of a certain field light emitting diode was low level, respective field was just lighted.When the negative electrode of a certain field was high level, respective field did not just work.
Referring to accompanying drawing 2, Fig. 5, described driver module is made up of two resistance and chip MC14543B; Two resistance wherein are connected between each incoming line and the ground wire; The input side of this chip is connected in the middle of two resistance; The power pin VDD of this chip connects the 12V power supply, and this chip outgoing side pin A, B, C, D, E, F, G meet pin A, B, C, D, E, F, the G of eight hop count sign indicating number display tubes respectively.Chip MC14543B has and latchs, decoding, driving action.Use this chip to decipher, drive charactron and show the PLC input signal, and with data latching in chip, thereby make charactron continue to show, reduce the PLC resource and use.Described two resistance are 3.3K.
Referring to accompanying drawing 2, accompanying drawing 6, described signal input module is made up of 37 contact pin CD1-37P, receives far-end PLC through data line, controlled by far-end PLC.
The utility model device is used for elevator system, can show the lifting degree of depth clearly, parameters such as pulling speed, thus make whole control process have ornamental, controllability.Adopt eight sections charactrons, clear display.Practice thrift cost, four output points of PLC are controlled the demonstration of charactron through coding chip MC14543B.
With regard to wherein one group (4 INADDs) implementation procedure of this use new device is analyzed as follows: numeral " 0-9 " changes binary-coded decimal in PLC inside into through program, and whether PLC exports high level according to four corresponding OPADDs of binary-coded decimal control then.For example, when detecting input, four INADDs that install are respectively: 0,0; 1;, when promptly 4 INADDs are distinguished corresponding low level, low level, high level, low level, make corresponding demonstration " 2 " at 0 o'clock through eight sections charactrons of coding chip control of digital display plate.Because of input signal is provided by PLC, input signal is the 24V level, in order to reach and chip coupling, adopts after two 3.3K electric resistance partial pressure dividing potential drops through not gate, to eight hop count sign indicating number tube cathodes low level is provided, and control is lighted.
Binary-coded decimal is adopted in the signal input; Accomplish the counting of 0-15 by 4 output points of PLC; This method can be saved the use of output point; In order to save the use of PLC output point greatly, device adopts four PLC output points to control the demonstration of two charactrons simultaneously, and for example: PLC DQ5.0, DQ5.1, DQ5.2, four output points of DQ5.3 are controlled the demonstration of charactron LG3 and LG8 simultaneously.LD sheet through 4543 selects the pin decision to which charactron output data.
Below be the 0-9 state of corresponding D C B A respectively, 0 represents low level, and 1 represents high level.
