Description

System and method for locking elevator doors when visitors bring out and bring in different items

An elevator control system and a method thereof, particularly a system and method for locking an elevator door when the articles carried out by a visitor are different from those brought in.

Elevator is a transportation tool that moves vertically to transport pedestrians or goods, and is a general term for vertical transportation tools in buildings. The elevator has a car running between at least two vertical rows or rigid guide rails with an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. According to statistics, elevators are also the most used vertical transportation tools in modern times.

When you want to take the elevator, you need to call the elevator car. Generally speaking, the call method of the elevator car is usually to press the up and down buttons set next to the elevator, so that the elevator control system receives the call signal and records the call. When the elevator car moves to the pressed button After the floor is reached, the elevator control system can clear the call in the record.

Since people and goods can be easily transported through elevators, it is easy for criminals to take advantage of the opportunity to transport stolen precious metals or large furniture through elevators during periods of low traffic. At present, most elevators are equipped with monitors, and some elevators have a more secure security mechanism, such as the need to use proximity cards or passwords to start the elevator, etc., but if the building is neglected or the building is not fixed Residents, deliberate criminals can still control the elevator to transport people or items.

To sum up, it can be seen that there has been a long-standing problem in the prior art that the elevator cannot be used by criminals for stealing, so it is necessary to propose an improved technical means to solve this problem.

In view of the problem that the prior art cannot ensure that the elevator is not used by criminals as a thief, the present invention discloses a system and method for locking the elevator door when the items brought out by the visitor are different from those brought in, wherein:

The system disclosed by the present invention for locking the elevator door when the articles carried out by the visitor are different from those brought in, at least comprises: a feature acquisition module for acquiring the biological characteristics of the caller when the elevator car is called; an identity determination module , used to judge whether the caller is a visitor according to biometric features, and when judging whether the caller is a visitor, whether the caller is visiting or leaving, and when judging that the caller is a visitor, confirming that the caller has visited The target home; the item detection module is used to detect the items carried by the caller when the caller is visiting, and used to detect the items carried by the caller when the caller is leaving; item comparison The module is used to compare the items taken out and the items brought in; the prompt module is used to prompt the resident or administrator of the target house when the item comparison module judges that the items taken out are more than those brought in; the receiving module , used to receive the confirmation message sent by the resident; the operation control module is used to control the car door of the car to keep open when the item comparison module judges that the items carried out are more than the items carried in, and to control the door of the car to remain open in the receiving mode. After receiving the confirmation message, the group controls the car door to close and operate normally.

The method disclosed by the present invention for locking the elevator door when the articles carried out by the visitor are different from those brought in, the steps of which at least include: obtaining the biological characteristics of the caller when the car of the elevator is called; judging that the caller is a visitor according to the biological characteristics, And after judging that the caller is a visitor, detect the items brought in by the caller, and confirm the target home that the caller visited; judge that the caller is a visitor according to the biometrics, and after judging that the caller is leaving, detect the caller again When it is judged that the items carried out are more than those brought in, the car door of the control car will remain open, and the resident or administrator of the target house will be prompted; after receiving the confirmation message sent by the resident, the car of the car will be controlled The door is closed and functioning normally.

The system and method disclosed by the present invention are as above, and the difference between the system and the prior art lies in that when the caller of the elevator is determined to be a visitor, the present invention detects the items carried by the caller before and after visiting the occupant, and determines that the items carried out are relatively small. When a lot of items are brought in, the car door of the elevator will be kept open, and the occupant will be notified at the same time, until the occupant confirms, the elevator and the car door will be controlled to operate normally, so as to solve the problems existing in the previous technology, and can improve the security effect and remind visitors.

Next, an embodiment is used to explain the operation system and method of the present invention, and please refer to "Fig. 2A" for the flow chart of the method for locking the elevator door when the visitor brings out and brings in different articles. In this embodiment, it is assumed that the elevator to which the present invention is applied is installed in a building, and the elevator includes two cars, but the present invention is not limited thereto.

First, occupants of all homes in the building can upload their biometrics to the building's server storage first. In this embodiment, assuming that the biometric feature is a fingerprint, the resident can upload the fingerprint to the server in the building using the communication device installed in the administrator's room or home.

Afterwards, when a caller calls the elevator car, the feature obtaining module 110 may obtain the biometric feature of the caller (step 210). In this embodiment, it is assumed that the feature acquisition module 110 can sense the fingerprint of the caller when the caller presses the call button through the fingerprint sensor disposed in the call button of the elevator.

After the feature obtaining module 110 obtains the biometrics of the caller (step 210 ), the identity determining module 120 may determine the identity of the caller according to the biometrics obtained by the feature obtaining module 110 (step 220 ). In this embodiment, it is assumed that the identity judging module 120 can judge whether the identity of the caller is a resident or a visitor, that is, whether the caller is a resident or a visitor.

If the identity judging module 120 judges that the identity of the caller is a visitor, the identity judging module 120 can further judge whether the caller is visiting or leaving, that is, whether the caller is visiting or whether it is leaving. In this embodiment, it is assumed that the identity judging module 120 can judge whether the caller is a visitor according to the location where the caller calls the elevator and the number of times the caller calls the elevator within a certain period of time. For example, when the caller calls at the entrance of the building elevator, and the identity judging module 120 judges that the caller is calling the elevator for the first time, then the identity judging module 120 can base on the caller's visit.

After the identity determination module 120 determines that the caller is visiting, the item detection module 130 may detect the items carried by the caller (step 230 ). In this embodiment, it is assumed that the item detection module 130 includes one or more near-end communication units, and different kinds of near-end communication units use different near-end communication technologies such as RFID and NFC, wherein each near-end communication unit is respectively Set at different heights of the elevator car door. When the caller enters the car, the near-end communication unit can detect the articles carried by the caller through the near-end communication technology, and at the same time read and store the information of the visited articles on the caller.

After the identity judging module 120 judges that the caller is visiting and the caller exits the elevator car, the identity judging module 120 can confirm the target home visited by the caller (step 240 ). In this embodiment, it is assumed that the identity judging module 120 can be connected to a monitoring system installed in the building, and obtains a screen from the monitoring system that can capture the caller's monitor, and judges the caller's visit according to the obtained screen. The target home that the caller entered.

Afterwards, when the caller leaves the visited target home and presses the call button to call the elevator car, the feature obtaining module 110 can obtain the biological feature of the caller (step 210 ), and the identity judging module 120 can obtain the biometric feature according to the feature The biometric features obtained by the module 110 determine the identity of the caller (step 220). In this embodiment, it is assumed that the identity judging module 120 can judge that the caller is a visitor according to the biometric characteristics of the caller being recorded only once, and can judge that the caller is leaving according to the location where the caller called the elevator is in the building, Then, after the elevator car moves to the floor where the caller is located and the car door is opened, the article detection module 130 can detect the carried out articles carried by the caller when the caller passes through the car door (step 250 ). In this embodiment, the item detection module 130 can detect the carried-out item in the same way as the detection of the carried-in item, so it will not be described further.

After the item detection module 130 detects the carry-out items carried by the caller, the item comparison module 140 can compare the carry-out items carried by the caller detected by the item detection module 130 with the carry-in items thing. When the item comparison module 140 determines that the items carried out are less than the items carried in, the prompting module 150 can display a text message and/or play a voice message to prompt the caller, so as to prevent the caller from forgetting the items in the target home. go.

And if the item comparison module 140 determines that the carried-out items are more than the carried-in items, the operation control module 190 can control the car door of the elevator car to remain open and not closed, which means that the control car door cannot be closed using the keys inside the car At the same time, the prompting module 150 can generate a prompting message and send the prompting message to the resident of the target house and/or the administrator room of the building confirmed by the identity determination module 120, so as to prompt the resident of the target house and/or the administrator of the building (step 260). In this embodiment, it is assumed that the prompting module 150 can generate a prompting message indicating that the caller has taken out the item from the target house, and can transmit it to the communication device installed in the target house and/or the administrator room through a wired or wireless network, Make the communication device display the prompt message and play the prompt sound or play the prompt message by voice, and the prompt module 150 can also read the communication data corresponding to the resident and/or administrator of the target house, and use the short message, instant message, Provide reminder messages to the occupants of the target residence and/or the building administrator by means of email, push broadcast, etc.

In practice, after the item detection module 130 detects the carry-out item carried by the caller (step 250 ), the operation control module 190 can first determine whether the receiving module 160 is as shown in the flow of “FIG. 2B”. Receive the confirmation message sent by the occupant of the target home (step 253), if so, control the operation of the elevator car normally, that is, the door of the elevator car that normally controls the elevator car is closed and moved to the floor the caller wants to go to (step 253) 273), if not, as described above, the operation control module 190 can control the door of the elevator car to remain open and not closed, and the prompting module 150 can prompt the occupant of the target home and/or the administrator of the building (step 260) .

In addition, when the identity judging module 120 judges that the caller is a visitor and judges that the caller is leaving, the operation control module 190 can also, as shown in the flow of "Fig. 2C", firstly detect the status of all the cars of the elevator. Use status (step 255 ), and select a car with no passengers according to the status of use, and control the selected car without passengers to move to the floor where the caller is located (step 257 ), after that, compare the load-by-item The module 140 compares the outgoing articles and incoming articles carried by the caller detected by the article detecting module 130 .

Returning to "Fig. 2A", after the operation control module 190 controls the door of the elevator car to remain open and not closed, and the prompt module 150 prompts the resident of the target home and/or the administrator of the building (step 260), the target The resident of the home can receive the prompt message and can choose to send a confirmation message back to the receiving module 160 . In this embodiment, the resident of the target house can operate the communication device provided in the target house or the computing device that has received the prompt message to send back a confirmation message.

After the receiving module 160 receives the confirmation message returned by the resident of the target home, the operation control module 190 can control the door of the elevator car to close normally, and control the elevator car to operate normally (step 270 ), that is, control the The elevator car moves to the floor the caller wants to go to, eg the first floor.

In this way, through the present invention, it can be detected whether the caller takes out the items of the visited person's home without the consent of the visited person before the caller enters the elevator car or when entering the elevator car, so as to improve the security effect.

In addition, when the identity determination module 120 determines that the caller is a resident according to the biometrics acquired by the characteristic acquisition module 110 (step 220 ), as shown in the flow of “FIG. 2D”, the physiological detection module 170 may detect The physiological state of the caller is measured (step 281 ). The data processing module 180 can read out the historical physiological data of the caller according to the biometrics obtained by the feature obtaining module 110 and compare the data detected by the physiological detection module 170 The physiological state and the read historical physiological data are used to determine whether the physiological state of the caller is abnormal, and the prompting module 150 can prompt the caller when the data processing module 180 determines that the physiological data of the caller is abnormal (step 285 ).

The data processing module 180 can also read out the historical boarding record of the caller according to the biometric feature acquired by the feature acquiring module 110 (step 291 ), and determine the floor that the caller wants to go to according to the read out historical boarding record, and automatically. After the elevator car is controlled to move to the floor the caller wants to go to, the car door of the car is opened (step 295 ).

To sum up, it can be seen that the difference between the present invention and the prior art is that when it is judged that the caller of the elevator is a visitor, the items carried by the caller before and after visiting the resident are detected, and when it is judged that the items carried out are more than those carried in At the same time, the car door that controls the elevator is kept open, and the occupant is notified until the occupant confirms the technical means of controlling the normal operation of the elevator and the car door. This technical means can solve the problem of the prior art that cannot ensure that the elevator is not blocked by criminals. As a problem of theft and use, it can achieve the technical effect of improving the security effect and reminding visitors that the missing items have not been brought back.

Furthermore, the method of locking the elevator door when the visitor brings out and brings in different articles of the present invention can be implemented in hardware, software, or a combination of hardware and software, and can also be implemented in a computer system in a centralized manner or in a computer system. A decentralized implementation in which different components are spread across several interconnected computer systems.
