Detailed description of the invention

Below in conjunction with accompanying drawing and preferred embodiment, technical scheme of the present invention is described in detail.

Wherein in an embodiment, shown in Figure 1, a kind of elevator outer-office calling electron plate floor ID method to set up, the method comprises the following steps:

S100 gathers the magnitude of voltage of wire in each outer-office calling electron plate corresponding position, and described wire to be arranged in elevator hoistways and to be connected to form loop with power supply.This step arranges at least one wire in elevator hoistways, and wire is connected to form loop with power supply, wherein the length of wire can need be carried out according to reality the actual conditions of elevator outer-office calling electron plate that No. ID, floor arranges and set, when the length of wire is less than the height of elevator hoistways, the setting of No. ID, floor then can be carried out to the part elevator outer-office calling electron plate in physics floor, when the length of wire is greater than or equal to the height of elevator hoistways, then can carry out the setting of No. ID, floor to whole elevator outer-office calling electron plates of physics floor.Because wire self exists certain resistance, the resistance of wire is relevant with the length L of the electricalresistivityρ of wire, wire and the cross-sectional area S of wire, as shown in formula (1),

$R=\frac{\mathrm{\ρ}L}{S}---\left(1\right)$

Therefore for the wire in elevator hoistways, wire can be approximately the resistance of multiple series connection, and each elevator outer-office calling electron plate is all connected with the resistance after series connection, the schematic diagram of elevator outer-office calling electron plate floor ID method to set up shown in Figure 2, suppose that the power supply U be connected with wire is positioned at top layer herein, therefore bottom outer-office calling electron plate is the low pressure side of wire, top layer outer-office calling electron plate is the high pressure side of wire, according to the correspondence position of each outer-office calling electron plate on wire, wire in elevator hoistways is approximately n+1 resistance, i.e. resistance R ₁, R ₂..., R _n, r, one end contact resistance R of bottom outer-office calling electron plate ₁with resistance R ₂node, one end contact resistance R of 2 layers of outer-office calling electron plate ₂with resistance R ₃node, other floors by that analogy, one end contact resistance R of top layer outer-office calling electron plate _nwith the node of resistance r, the other end of the outer-office calling electron plate of all floors is all connected with the master control board of elevator device by universal serial bus, as shown in Figure 2, i-th layer of outer-office calling electron plate magnitude of voltage U on wire correspondence position _ifor

$U_i=\frac{\underset{j=1}{\overset{i}{\Σ}}{R}_j}{r+\underset{j=1}{\overset{n}{\Σ}}{R}_j}U,i\≤n---\left(2\right)$

S110 carries out analogue to digital conversion respectively to magnitude of voltage described in each, obtains corresponding ADC value.Step S100 collects the magnitude of voltage of wire in each outer-office calling electron plate corresponding position, but owing to can not directly process gathered magnitude of voltage, and need magnitude of voltage to convert to digital quantity, therefore this step carries out analogue to digital conversion respectively to each collected magnitude of voltage, magnitude of voltage is converted into the ADC value that micro controller system etc. can process;

Described ADC value is stored in corresponding described outer-office calling electron plate as No. ID, floor by S120.Due to the magnitude of voltage that all correspondence one is unique of each outer-office calling electron plate in the present embodiment, namely the ADC value that all correspondence one is unique, therefore, after collected magnitude of voltage being converted to corresponding ADC value, using the ADC value of correspondence as No. ID, floor, and ADC value is stored in corresponding outer-office calling electron plate, the so far setting of No. ID, elevator outer-office calling electron plate floor completes.The pressure drop that the elevator outer-office calling electron plate floor ID method to set up that the present embodiment proposes utilizes the wire in elevator hoistways to cause due to the resistance self existed, gather the magnitude of voltage of different outer-office calling electron plate corresponding position on wire, the ADC value obtained after carrying out analogue to digital conversion to each magnitude of voltage is stored it as No. ID, the floor of the outer-office calling electron plate of correspondence, make to the setting of No. ID, floor that not only efficiency is high, accuracy is high, and it is irrelevant with the running state of elevator to carry out the setting of No. ID, floor, do not affect the normal operation of elevator.

$U_i=\frac{{\mathrm{\ρH}}_i/S}{\mathrm{\ρ}H/S}U=\frac{H_i}{H}U---\left(3\right)$

Wherein, H _iit is the height at i-th layer of outer-office calling electron plate place place, H is the length of wire, U is supply voltage value, therefore i-th layer of outer-office calling electron plate magnitude of voltage of corresponding position on wire can be converted to the height at corresponding i-th layer of outer-office calling electron plate place place according to formula (3), namely the i-th corresponding floor layer height, as shown in Figure 2, the micro controller system built-in due to outer-office calling electron plate is integrated with analog-to-digital conversion module, therefore when carrying out analogue to digital conversion, can be realized by the analog-to-digital conversion module that the built-in micro controller system of outer-office calling electron plate is integrated, only the magnitude of voltage collected need be sent to outer-office calling electron plate, micro controller system in outer-office calling electron plate just can complete analogue to digital conversion, specifically, for there is the micro controller system of 8 sampling precisions, can according to story height when carrying out analogue to digital conversion, the length of wire and the sampling precision of magnitude of voltage calculate and obtain ADC value corresponding to magnitude of voltage, as shown in formula (4), ADC value D _ifor

$D_i=\frac{U_i}{U}\·2^N=\frac{H_i}{H}\·2^N=\frac{H_i}{H}\·2^8---\left(4\right)$

Now, the ADC value obtained according to formula (4) is No. ID, the floor of the correspondence that outer-office calling electron plate stores.The magnitude of voltage collected is converted to corresponding story height by present embodiment, calculate according to the length of story height, wire and the sampling precision of magnitude of voltage again and obtain ADC value corresponding to magnitude of voltage, realize on the one hand converting analog signal to outer-office calling electron plate accessible digital signal, obtain No. ID, the floor of outer-office calling electron plate, being convenient to apparatus for controlling elevator can calculate No. ID, the floor stored with outer-office calling electron plate according to story height on the other hand, thus enables apparatus for controlling elevator identify the calling information of different outer-office calling electron plate.

For elevator device, in master control specification table, set the height H of i-th layer of outer-office calling electron plate corresponding position respectively _iafter the length H of wire and the sampling precision of magnitude of voltage, just direct derivation No. ID, the floor of every one deck outer-office calling electron plate can be gone out according to formula (1) ~ (4), as shown in table 1, and No. ID, the floor the derived floor ID one_to_one corresponding that store interior with each outer-office calling electron plate, main elevator control plate just can be communicated with each outer-office calling electron plate by No. ID, floor, thus identifies the calling information of each outer-office calling electron plate.

As a kind of concrete embodiment, the length of wire is identical with the height of elevator hoistways, thus while making the whole elevator outer-office calling electron plates in physics floor all can realize the setting of No. ID, floor, saves wire as much as possible, reduce costs.
