During detection, a card detection identification device is adopted to carry out card reading identification on an operator passing through a shielding channel, the number uniqueness of active identification cards carried by the operator is judged according to the number of the read IDs of the active identification cards, if the IDs of the active identification cards are unique, the identity information stored by the active identification cards is transmitted to a system server for subsequent step detection, otherwise, the operator is judged not to meet the identity uniqueness; adopting a portrait recognition device to carry out facial recognition and comparison on an operator passing through a shielding channel, judging identity information of the operator, sending the judged identity information to a system server, comparing the identity information transmitted by a card detection recognition device with the identity information of the portrait recognition device by the system server, and judging that the operator meets identity uniqueness if the identity information is the same as the identity information of the portrait recognition device; otherwise, judging that the operator does not meet the identity uniqueness.
Specifically, in a detection period, namely when the infrared detection module detects a detection signal that someone enters the shielding channel, the card readers start to read cards until the detection signal of the infrared detection module disappears, the ID read by each card reader when the duration of the detection signal reaches or exceeds a set time threshold is obtained, the same IDs in all the card readers are counted, the counted number is the number of the card readers reading the ID, and the IDs with the counted number of 1 are rejected, namely the IDs read by only one card reader are rejected; the misreading of remote cards, i.e., cards outside the shielded channel, is prevented.
And then screening out the valid ID in each card reader, and judging the ID read at least three times continuously in one detection period in each card reader as the valid ID. Comparing the effective IDs in each card reader, and if all the effective IDs are the same ID, judging that the identity uniqueness of the operator is met; otherwise, judging that the operator does not meet the identity uniqueness. Specifically, one detection cycle is the duration of the detection signal when the infrared detection module detects that someone enters the shielding channel and the duration of the detection signal reaches or exceeds a set time threshold.
when detecting the object, the steps are as followsCan also be used forThe exchange sequence is carried out, namely effective IDs in each card reader are screened out firstly, specifically, when the infrared detection module detects a detection signal that someone enters the shielding channel, the card readers start to read the card until the detection signal of the infrared detection module disappears, the ID read by each card reader when the duration of the detection signal reaches or exceeds a set time threshold is obtained, and the ID read by each card reader for at least three times continuously is judged as the ID read in each card readerA valid ID.
Then counting the same effective IDs in all the card readers, wherein the counted number is the number of the card readers reading the effective IDs, and eliminating the effective IDs with the counted number of 1, namely the effective IDs read by only one card reader; comparing the remaining valid IDs, and if all the valid IDs are the same ID, judging that the identity uniqueness of the operator is met; otherwise, judging that the operator does not meet the identity uniqueness.
In another embodiment, on the basis of the above embodiments, when the card reader reads the card, it is further required to read RSSI data of each active identification card, that is, received signal strength, all the card readers synchronously scan and have the same scanning frequency, each active identification card is in one detection period, the RSSI data read each time is Rmn, where m is the number of the card reader reading the active identification card, and n is the nth scanning card reading time of the card reader in one detection period; if the number of the final different effective IDs is more than 2, the following steps are continuously adopted for further detection:
Grouping the different effective IDs in pairs, selecting a card reader with relatively large RSSI data to be read from the card reader which simultaneously reads the group of effective IDs for each group of effective IDs, and acquiring RSSI data which are respectively scanned and read by the effective IDs in the group at least three time points on the card reader, wherein the RSSI data are respectively Rma, Rmb and Rmc, namely n is respectively equal to a, b and c; dividing the difference between Rma and Rmb of each effective ID by the difference between Rma and Rmc to obtain the relative change rate of the signal intensity of each effective ID; if the difference value of the signal intensity relative change rates of the two effective IDs in the group is smaller than a set change rate threshold value, judging that the operator simultaneously carries two active identification cards corresponding to the group of effective IDs; otherwise, the operator is judged not to simultaneously carry the two active identification cards corresponding to the group of effective IDs.
If all groups judge that the operator does not simultaneously carry two active identification cards corresponding to the group of valid IDs, judging that the operator meets identity uniqueness; otherwise, judging that the operator does not meet the identity uniqueness.
Because the active identification card is usually fixed on the staff, if the staff carries a plurality of cards on one's body simultaneously, the relative position of these cards is fixed, along with staff's removal, its signal strength's rate of change is close, like this, can further avoid the influence of external active identification card signal to the testing result.
By adopting the detection system, a downhole operator sequentially passes through the shielding channel by one person, and the shielding channel is utilized to shield the emission signal of the external active identification card, so that the card detection identification device in the shielding channel can only receive the emission signal of the active identification card carried by the operator in the shielding channel, and whether the operator carries a plurality of active identification cards or not can be judged according to the received ID of the active identification card, if only one active identification card signal is detected, the operator only carries one active identification card, namely, the number uniqueness is met, otherwise, the number uniqueness is not met; meanwhile, the system server is utilized to judge whether the identity information of the operator is consistent with the identity information of the active identification card, whether the operator has a tape missing behavior, a tape multi-tape behavior or a tape replacement behavior can be comprehensively judged, the operator is judged to meet the identity uniqueness only when the identity information of the operator is consistent with the identity information of the carried active identification card and the number uniqueness of the carried active identification card is met, the entrance guard release device releases the operator, and otherwise the operator is forbidden. Therefore, the shielding channel shields the external active identification card signal, the identification difficulty of the card detection identification device is reduced, the identification speed of the card detection identification device is increased, the passing efficiency of an operator is improved, identity consistency judgment is carried out through the portrait identification device, and the operator can be prevented from taking the place of the active identification card.
The above description is only exemplary of the present invention and should not be taken as limiting, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
