It should be noted that the flow charts shown in the drawings are only exemplary and do not necessarily include all the contents and operations/steps, nor do they necessarily have to be executed in the order described. For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.
In a first embodiment, as shown in fig. 1 and 2, in order to deal with the situation that after face verification of authorized staff is performed, unauthorized personnel actively cooperate to pass through an access control to maliciously destroy facilities of a nuclear power plant, the invention constructs a passing verification method of the nuclear power plant, which is applied to the access control of the nuclear power plant to verify the identity of personnel entering the nuclear power plant, and preferably selects one access control. Specifically, the method comprises the following steps:
step S1: after the verification personnel are judged to be authorized personnel, the access control is controlled to be released;
step S2: acquiring biological characteristic data of the passer through second characteristic acquisition equipment after the entrance guard, comparing the biological characteristic data of the authorized personnel, and judging whether the passer is consistent with the verification personnel;
step S3: if not, an alarm signal is generated.
In this embodiment, the step S1 includes: step S0: the method comprises the steps that biological characteristic data of a verifier are collected through a first characteristic collecting device before entrance guard, and are compared with the pre-stored biological characteristic data of an authorized person, and whether the verifier is the authorized person is judged. Accordingly, step S1: after the verification personnel are judged to be authorized personnel, the access control is controlled to be released; and after judging that the verification personnel is not authorized personnel, controlling the entrance guard to be locked and generating an alarm signal.
In this embodiment, the pre-stored biometric data of the authorized person and the biometric data of the verified person collected by the first feature collecting device may be one or more of face feature data, pupil feature data, fingerprint feature data, and voiceprint feature data, respectively.
Since the unauthorized person does not actively perform active authentication such as fingerprint and voiceprint after entering the nuclear power plant, the biometric data of the authorized person acquired by the second feature acquisition device is other passive authentication such as face feature data and/or pupil feature data.
Moreover, it should be noted that the biometric data of the verifying person collected by the first feature collecting device may be the same as or different from the biometric data of the passer collected by the second feature collecting device, so that it is designed to compare the collected biometric data of the passer with the biometric data of the authorized person, rather than with the biometric data of the verifying person.
Preferably, the first feature acquisition device and the second feature acquisition device are both face acquisition cameras, and face feature data are obtained through shooting face images and analyzing.

Specifically, after the person to be authenticated is judged to be the authorized person, the biological characteristic data of the authorized person is extracted, preparation is made for subsequent authentication of the person to be authenticated in advance, after the biological characteristic data of the person to be authenticated is acquired by the second characteristic acquisition device, whether the person to be authenticated is judged to be the authorized person can be immediately judged according to the extracted and prestored biological characteristic data of the authorized person, and the biological characteristic data of the authorized person is various, so that whether the person to be authenticated and the person to be authenticated belong to the authorized person can be verified in various modes, namely whether the person to be authenticated is consistent with the person to be authenticated. In addition, when the second characteristic acquisition equipment does not acquire the biological characteristic data of the passer, a signal that the passer does not pass can be output.
In some embodiments, although the entrance guard generally allows only one person to pass through, sometimes two persons can pass through, so that, in order to avoid that an unauthorized person passes through with an authorized person and passes through the verification that the authorized person escapes through the second feature collecting device, the step S2 is preceded by: detecting the number of the passing personnel through the detection equipment after the entrance guard, judging whether the number of the passing personnel is larger than one person, if so, generating an alarm signal, and if not, executing the step S2.
In this embodiment, the existing nuclear power personnel can only send an alarm by means of a password keyboard when being held in the nuclear power plant, for example, the normal pass verification password is 1234, the pass verification password for generating the alarm signal is 01234, and when the processing device receives the password of 01234, the processing device generates the alarm signal. The invention can secretly collect the biological characteristic data of the passer through the second characteristic collecting device after the entrance guard, compare the biological characteristic data with the biological characteristic data of the authorized person, judge whether the passer is consistent with the verification person, and if not, generate an alarm signal. In order to ensure the life safety of personnel, the alarm signal is a hidden signal, namely, the alarm signal is not an audible and visual alarm, and the like, and the alarm signal is sent to a security system or security equipment, so that security personnel can know the alarm event, and the requirement that the personnel can secretly send the alarm signal when stressed is met.
