The elevator Bluetooth terminal 3B can also receive the processing result sent back by the elevator controller. For example, the elevator Bluetooth terminal and the elevator controller can communicate in a 232 mode or a 485 mode.

In the present embodiment, referring to fig. 3, the mobile terminal apparatus 4 is a mobile terminal. For example, the mobile terminal may be a smart phone or a smart wearable device. From a production point of view, the mobile terminal device 4 may not be included in the control system of a contactless elevator ride public elevator.

The mobile terminal 4 may run a program for calling and selecting a target floor, i.e. a boarding program, and may specifically be a runnable Application (APP) or applet. By way of example, the applet may be a WeChat applet or a Payment Boolean applet. The APP may be installed into the mobile terminal 4 by system implantation, pre-installation or post-installation, etc.

The mobile terminal 4 can establish connection with the elevator Bluetooth terminal 3B through Bluetooth. The elevator user inputs floor selection information through the mobile terminal 4, and the mobile terminal 4 forwards the information to the corresponding elevator controller through Bluetooth, so that the functions of calling the elevator and selecting the floor are realized.

In the present embodiment, referring to fig. 7, the elevator bluetooth terminal 3B includes a first elevator bluetooth terminal 3B1 and a second elevator bluetooth terminal 3B 2; the call elevator controller 11 and the first elevator Bluetooth terminal 3B1 are installed near the elevator entrance of the elevator for calling; the floor control elevator controller 12 and the second elevator Bluetooth terminal 3B2 are installed in the elevator car of the elevator and used for floor selection; in order to be suitable for a scene that a plurality of people take the elevator at the same time, the elevator Bluetooth terminal 3B can provide a plurality of Bluetooth communication channels, can communicate with a plurality of mobile terminals at the same time, and meets the requirement that a plurality of people take the elevator at the same time.

The method of the present embodiment for taking a public elevator without contact will be described with reference to fig. 1.

Step L1, a first signal sent by the mobile terminal device is received.

In this embodiment, step L1 is performed by elevator bluetooth terminal 3B.

The elevator Bluetooth terminal 3B can send out elevator information within a preset range near the elevator, and particularly sends out the elevator information in a broadcasting signal mode. When the elevator user walks to the elevator within the preset range, the APP or the applet of the mobile terminal 4 can scan the broadcast signal sent by the elevator Bluetooth terminal 3B installed on the elevator, and can display the accessible floors for selection on the screen according to the equipment information contained in the received broadcast signal, or directly input the destination floors to be accessed on the mobile terminal 4 by the elevator user on the display interface. Wherein, the equipment information contained in the broadcast signal is the information of the elevator which can be taken.

After elevator user's input ended, the APP or the applet of mobile terminal 4 looked for the idle passageway that elevator bluetooth terminal 3B provided, let mobile terminal 4 and elevator bluetooth terminal 3B establish and be connected, start point-to-point communication. The mobile terminal 4 establishes connection with the elevator Bluetooth terminal 3B to indicate that the elevator Bluetooth terminal 3B is a service terminal device capable of taking an elevator; the elevator Bluetooth terminal 3B which can take the elevator is relative to other elevator Bluetooth terminals 3B, and the elevator Bluetooth terminal 3B indicates that an elevator user is currently allowed to take the elevator through the elevator Bluetooth terminal 3B. The operation of the elevator user on the mobile terminal device, namely the mobile terminal 4, enables the mobile terminal 4 to send a first signal to the elevator Bluetooth terminal 3B which can take the elevator; the first signal includes the elevator taking requirement information, such as the information of the floor or the uplink and downlink information which the elevator user wants to go to. The elevator Bluetooth terminal 3B receives the first signal sent by the mobile terminal 4.

Step L2, an elevator control signal is generated based on the first signal.

In the present embodiment, step L2 is performed by elevator bluetooth terminal 3B.

After receiving the first signal, the elevator Bluetooth terminal 3B generates an elevator control signal in an open authority mode based on the first signal. The elevator control signal is generated in an open permission mode, that is, any mobile terminal 4 can communicate with the elevator bluetooth terminal 3B, and an operation request (for example, a request for going to a destination floor) of any mobile terminal 4 can reach the elevator bluetooth terminal 3B and form the elevator control signal.

After the bluetooth communication channel is established, the APP or applet of the mobile terminal 4 sends the destination floor information input by the elevator user to the elevator bluetooth terminal 3B. After receiving the information, the Bluetooth module of the elevator Bluetooth terminal 3B can automatically disconnect the connection with the mobile terminal 4, and an access is freed for other elevator users to use, and meanwhile, the received information is sent to the elevator controller 1 in an elevator control signal mode through an RS485 mode to be processed. The elevator controller 1 receives an elevator control signal.

And L3, controlling the car corresponding to the target elevator object to move to a specified position according to the elevator control signal, and feeding back the control result to the user through the mobile terminal device or the elevator button.

In the embodiment, the step L3 is executed by the elevator controller 1, the elevator controller 1 receives an elevator control signal, and performs a corresponding action according to information contained in the elevator control signal, specifically, the elevator controller 1 controls a key trigger unit corresponding to a target elevator object according to the elevator control signal to start a designated key corresponding to the target elevator object, so that a car corresponding to the target elevator object moves to a designated position, for example, an elevator corresponding to the elevator Bluetooth terminal 3B is an elevator to be taken by an elevator user, namely, the target elevator object, after receiving the elevator control signal, the elevator controller 1 simulates that a person presses a key down according to a target floor contained in the elevator control signal and according to actual needs, the relay corresponding to an upper call key, the relay corresponding to a lower call key or the relay corresponding to the target floor key for a certain time, so as to drive the original elevator system, namely, so that the car corresponding to the elevator terminal 3B goes to a corresponding floor, and realize elevator taking, in other embodiments, the step L3 is executed by the original elevator system, and the elevator controller 1 feeds back a control result to the user (e.g. the elevator user) through the mobile terminal 4 to give a prompt that the elevator user successfully operates the.

Step L3 can be divided into a call process and a floor control process.

For the calling process, the calling elevator controller 11 controls the key trigger unit 2 corresponding to the calling elevator controller 11 to start the appointed key corresponding to the calling elevator controller 11 according to the first elevator control signal received from the first elevator Bluetooth terminal 3B 1. Wherein the first elevator control signal is for calling. Specifically, the call elevator controller 11 compares the floor where the call elevator controller 11 is set in advance with a target floor, and if the floor where the call elevator controller 11 is located is smaller than the target floor, the control key triggering unit 2 absorbs a relay corresponding to the upper call key; if the floor where the elevator calling controller 11 is located is larger than the target floor, the control key triggering unit 2 attracts a relay corresponding to the lower calling key, and the fact that a person presses the upper calling key or the lower calling key is simulated. In this way, the car corresponding to the call elevator controller 11 can be moved to the floor where the call elevator controller 11 is located, that is, the first designated position.

For the floor control process, the floor control elevator controller 12 receives a second elevator control signal sent by a second elevator bluetooth terminal 3B 2; illustratively, after the car moves to the first designated position to open the door, the cloud server 3A sends a second elevator control signal to the floor control elevator controller 12 located within the car. Wherein the second elevator control signal is used for floor control. The floor-controlled elevator controller 12 controls the key triggering unit 2 corresponding to the floor-controlled elevator controller 12 to start the designated key corresponding to the floor-controlled elevator controller 12 according to the second elevator control signal. Specifically, the floor control elevator controller 12 controls the key trigger unit 2 to attract the relay corresponding to the target floor key for a certain time, and simulates that someone presses the target floor key. Therefore, the elevator system can be driven to enable the elevator car corresponding to the floor control elevator controller 12 to move to the corresponding floor, namely the second appointed position, so that the elevator can be taken.

In the present embodiment, the designated positions include a first designated position and a second designated position. The first designated location is also the floor where the elevator user is located; the second designated location is then also the floor to which the elevator user wants to go.

On the same floor, a subsequent elevator user may not call again if it happens that the elevator user has made a call. If the destination floor has been selected after the arrival of the car at the same floor, the subsequent elevator users can no longer take floor control.

According to the above, the present embodiment achieves the purpose of taking public elevators without contact by inputting the destination floor on the mobile terminal 4 instead of pressing the elevator key through the APP or the applet unified throughout the society (the user can install the APP or the applet by himself, for example, by scanning the two-dimensional code), and can cultivate the new life habit of using the elevator safely and healthily throughout the society, thereby solving the problem of spreading infectious viruses through the elevator key. The device can also be used off-line and can be used in situations where the elevator control is not able to connect to an external network.

The embodiment is suitable for wide occasions, is suitable for places such as residential areas, hotels, office buildings and the like, and can be used in open public places such as hospitals and business circles. The elevator can be changed into an elevator which can be taken without pressing an elevator key through the embodiment as long as the elevator is used openly or is used in the open use time period in the whole society. This embodiment allows the elevator user to travel to each floor in a contactless manner without knowing the destination floor of the elevator user in advance.

The system stack of this embodiment is on former traditional button elevator, and all traditional button elevators can all install additional, will have the button trigger unit 2 of relay switching value and overlap with former elevator system, realize keeping apart with former elevator system, do not have the influence to former elevator system's function, can ensure the original security of elevator.

Second embodiment

The present embodiment is different from the first embodiment in that the control method for a contactless riding public elevator of the present embodiment further includes a step L0 of sending a second signal to wake up an elevator riding program on the mobile terminal device, and in the present embodiment, the step L0 is specifically to send the second signal to wake up the elevator riding program on the mobile terminal device to receive an elevator riding signal for riding an elevator.

Step L0 is performed before step L1 step L0 is performed by the elevator bluetooth terminal 3B, i.e., the second signal is sent by the elevator bluetooth terminal 3B.

Accordingly, the mobile terminal 4 performs steps C1 and C2.

And step C1, receiving a second signal sent by the accessible elevator or the accessory equipment thereof in the nearby preset range. The mobile terminal 4 receives a second signal sent by a device such as the elevator bluetooth terminal 3B within a predetermined range, wherein the second signal is a bluetooth Beacon signal. Wherein the bluetooth beacon signal may come from a bluetooth beacon device 5' as shown in fig. 9(a), which is disposed on an elevator door frame or on an elevator hall ceiling, etc. In this scenario, the elevator bluetooth terminal 3B is an accessory that can take an elevator. In other embodiments, the second signal is emitted by an available elevator within a predetermined range near the mobile terminal 4, such as the original elevator system.

Part or all of the APP functions (part or all of the programs) are implanted into the operating system layer of the mobile terminal device, namely the mobile terminal 4; some or all of the APPs implanted in the operating system are still running when the mobile terminal 4 is off-screen and standby, and may scan a second signal such as a bluetooth Beacon or voice. That is, a part of the partial or all programs implanted in the operating system of the mobile terminal 4 may be the first program when the mobile terminal 4 is off standby or scans the second signal all the time.

And step C2, waking up the elevator taking program according to the second signal to generate a first signal. Specifically, the elevator taking program is awakened according to the second signal to receive an elevator taking signal for taking the elevator, and then the first signal is generated.

The elevator taking program is awakened to receive a signal for taking the elevator, such as a call signal input by a user or a floor selection signal, and generate a first signal. When the first program of the mobile terminal 4 scans the second signal, such as a bluetooth Beacon or a voice signal with a specified characteristic, the mobile terminal 4 exits the standby state and receives a signal for taking the elevator, specifically, the elevator taking program receives an elevator taking signal for taking the elevator, for example, an input interface is automatically called to allow the user to input a destination floor.

The elevator bluetooth terminal 3B transmits a bluetooth broadcast of a specific type, i.e. a second signal, outwards. The second signal contains specific information as well as elevator information such as elevator controller type (containing key information), elevator open status information and elevator key layout information. The second signal may be used to determine the target elevator object and may be used to decide the manner in which the mobile terminal 4 receives the ride signal for riding the elevator, such as a voice input or a touch screen input.

The mobile terminal 4 in the screen-off state wakes up the elevator taking program on the mobile terminal 4 according to the second signal to receive an elevator taking signal for taking the elevator.

The boarding procedure is implanted in the operating system layer of the mobile terminal 4. After scanning the second signal, automatically waking up the elevator taking program to receive an elevator taking signal for taking the elevator, and directly entering an input interface to allow a user to select a key to be pressed; even though the mobile terminal 4 is locked, such as a screen lock, the locked state does not need to be released. For example, the mobile terminal 4 displays an input interface on the display screen according to the second signal, specifically, lets the user select a key according to the key information display interface received from the second signal, such as: for the calling process, displaying up and down keys for selection; for the layer selection process, displaying numbers and letters for input; then, the mobile terminal 4 generates a first signal according to a signal received from the display screen, such as a touch signal, and automatically sends the first signal to the elevator bluetooth terminal 3B that can take the elevator. The scheme is also suitable for the situation that the user is using the mobile terminal 4, for example, the user is using the mobile terminal 4 to send a short message, the mobile terminal 4 can also receive the second signal and awaken the elevator taking program according to the second signal to receive the signal for taking the elevator, and then the first signal is generated.

In other embodiments, after automatically waking up the elevator taking program, the elevator taking program of the mobile terminal 4 sends a signal to remind the user of inputting a voice signal, for example, by sending a sound, vibration or light signal; that is, voice input is prompted to allow the user to directly speak the name of the key to be pressed. The elevator taking program of the mobile terminal 4 generates a first signal according to the received voice signal; specifically, the elevator taking program automatically recognizes the key number represented by the voice signal, then generates a first signal and automatically sends the first signal when the mobile terminal 4 is in the screen-off state. In this way, the user can take the elevator without taking out the mobile terminal 4.

In other embodiments, step C2 specifically includes: although the mobile terminal 4 is released from the screen-off state, the elevator taking program is not implanted into the operating system layer of the mobile terminal 4, and cannot receive an elevator taking signal for taking an elevator; the previous elevator taking program is not run in the operating system of the mobile terminal 4, and after a user assistant program such as a voice assistant program on the mobile terminal 4 receives the second signal, the elevator taking program on the mobile terminal 4 is started; if the mobile terminal 4 is locked, for example, the screen lock, the locked state needs to be released first; the user assistant program is the first program; then, the elevator taking program of the mobile terminal 4 generates a first signal in the manner described above, for example, receives the input from the user to send the first signal to the elevator bluetooth terminal 3B capable of taking the elevator.

In other embodiments, the second signal is a Near Field Communication (NFC) signal, such as a magnetic field signal. Specifically, the control system for the contactless elevator comprises a sensor; the mobile terminal 4 approaches the sensor, and the sensor wakes up the elevator taking program on the mobile terminal 4 through the near field communication signal.

The second signal and the aforesaid information about the elevator that can be multiplied may be contained in the same signal (for example, a broadcast signal) or may be contained in two signals respectively.

This embodiment can accomplish opening APP and subsequent processes under the condition that mobile terminal 4 is not unlocked, can avoid the inconvenience that the unblock and need click mobile terminal 4 many times and bring.

Third embodiment

The difference between this embodiment and the second embodiment is that, referring to fig. 5, this embodiment further includes the second server device 6, and the second server device 6 executes step L1.

Referring to fig. 6, in the present embodiment, the second server device 6 is an information code reading device 6A.

The first signal is an information code, specifically a two-dimensional code, specifically as shown in fig. 9(b) at 5 ″. The boarding procedure of the mobile terminal 4 converts information input by the user, such as a key number, into a two-dimensional code. The user presents the information code to an information code reading device 6A such as a two-dimensional code reading device. The information code reading device 6A receives the information code, i.e., the first signal, transmitted by the mobile terminal device. Wherein the information code is represented in the form of an optical signal. The information code reading device 6A recognizes information such as key information in the information code, and gives the information code to the elevator controller 1, and the elevator controller 1 drives the elevator.

The information code reading device 6A acquires the calling and floor selection signals by identifying the information codes, converts the signals into information which can be received by the elevator controller and sends the information to the elevator controller for processing. The information code reading device 6A can also receive the processing result sent back by the elevator controller. For example, the information code reading device 6A and the elevator controller 1 may communicate using 232 mode or 485 mode.

In the present embodiment, the elevator controller 1 includes a call elevator controller 11 and a floor control elevator controller 12; referring to fig. 8, the information code reading device 6A includes a first information code reading device 6A1 and a second information code reading device 6A 2; the call elevator controller 11 and the first information code reading device 6a1 are installed near the elevator entrance of the elevator for calling; the floor-controlled elevator controller 12 and the second information code reading device 6a2 are installed in the car of the elevator for floor selection.

The information code is a two-dimensional code for taking the elevator. The first information code reading device 6a1 at the elevator entrance reads the elevator two-dimensional code presented by the user, the first information code reading device 6a1 analyzes the elevator two-dimensional code information, the obtained departure floor information and destination floor information are converted into signals which can be identified by the elevator controller 1 and are transmitted to the elevator calling controller 11 through RS232 or RS485, and the elevator calling controller 11 determines whether to call up or down according to the departure floor and the destination floor. After the car of the target elevator object reaches the departure floor, the user enters the elevator, the second information code reading device 6a2 reads the two-dimensional code for taking the elevator presented by the user, and the second information code reading device 6a2 converts the acquired target floor into a signal which can be recognized by the floor control elevator controller 12 and transmits the signal to the floor control elevator controller 12 through RS232 or RS 485.

According to the above, the purpose of the elevator taking is achieved by generating the elevator taking two-dimensional code information and reading the elevator taking two-dimensional code on the information code reading device 6A instead of pressing the elevator key, so that the problem that the infectious virus is spread through the elevator key is solved. The embodiment also has the advantages of the second embodiment, and the embodiment can be used without networking, and can be applied to various occasions.

Fourth embodiment

The present embodiment is different from the second embodiment in that the control method of the contactless ride-on public elevator of the present embodiment further includes step P1 and step P2.

And a step P1 of judging whether there are a plurality of elevators capable of riding in the preset range. The determination may be specifically realized by receiving an input signal.

In the present embodiment, step P1 is performed by mobile terminal 4. The input signal is in particular a second signal.

In step P2, when there are a plurality of elevators capable of riding within the predetermined range, the target elevator object is determined from the plurality of elevator objects based on the information on the capable of riding. The second signal contains information about available elevators.

Specifically, a target elevator object is determined from a plurality of elevator objects based on an input signal. The mobile terminal 4 sets the elevator object corresponding to the input signal having the strongest signal among the received plurality of input signals as the target elevator object. The arrangement of a plurality of elevators near the mobile terminal 4 can cause the mobile terminal 4 to scan a plurality of second signals or a plurality of elevator Bluetooth terminals, and the mobile terminal 4 judges which elevator the mobile terminal 4 is closer to according to the strength of the received Bluetooth signals, wherein the stronger the signal is, the closer the distance is, and the closest elevator is automatically taken as a target elevator object, namely, a riding and operating object. In other embodiments, the target elevator object is randomly determined from a plurality of elevator objects based on the input signal.

In other embodiments, receiving a second input signal is also included. Step P2 specifically includes: a target elevator object is determined from the plurality of elevator objects based on the second signal and the second input signal. Specifically, a plurality of candidate second signals are determined based on the second input signal, and the elevator object corresponding to the second signal with the strongest signal in the plurality of candidate second signals is used as the target elevator object. For example, in some situations with multiple elevators, the elevators are zoned, such as into high floor zone elevators and low floor zone elevators; the second signal is a broadcast signal sent by the elevator Bluetooth terminal 3B, and the second input signal is a destination floor input by an elevator user on the mobile terminal 4; the mobile terminal 4 determines an elevator subarea corresponding to the destination floor according to the second input signal, such as a high-floor area, so as to determine a plurality of candidate second signals from all the scanned second signals; then, the elevator object corresponding to the second signal with the strongest signal is selected from the plurality of candidate second signals as the target elevator object.

Fifth embodiment

The present embodiment differs from the fourth embodiment in that:

step P1 specifically includes: receiving a first position signal sent by an elevator Bluetooth terminal 3B; the first position signal is the input signal;

step P2 specifically includes: based on the first position signal, the elevator object which can be taken by the elevator and is closest to the elevator user is taken as the target elevator object.

Specifically, the information of the position or floor where the calling elevator controller 11 is installed is recorded by the calling elevator controller 11, and the information can be specifically set on the calling elevator controller 11; the first position signal is position information of each call elevator controller 11 stored by the cloud server; the cloud server serving as the third server device sends the first position signal to the mobile terminal 4; the mobile terminal 4 locates its own position through APP or applet, and then determines which elevator object the mobile terminal 4 is closest to based on the first position signal and its own position, thereby determining the target elevator object, i.e. which elevator the elevator user will take.

In other embodiments, the mobile terminal 4 sets the elevator-capable object corresponding to the second signal with the maximum intensity as the target elevator object based on the intensity of the second signal.

According to the embodiment of the invention, the floor selection signal and/or the calling signal are sent out through intelligent semantic recognition and a wireless network or Bluetooth, so that the elevator can be taken without pressing an elevator key.

The embodiment of the invention can also be used for elevators which have been set up before and need to be authorized to enter, such as elevators in a cell, so that the elevators are open to the outside, such as to persons living outside the cell.

Sixth embodiment

In practice, it often happens that when the target elevator travels to the first designated floor, the person calling the elevator fails to enter the elevator for various reasons, and at this time the elevator should not travel to the second designated floor and stop and open the elevator door at that floor. For this reason, the present embodiment adopts the following method:

when the target elevator object arrives at the first appointed floor determined by the first position signal and carries passengers, the following steps are also executed: t1: confirming that the mobile terminal equipment enters a car of a target elevator object; t2: the control target elevator object lights a button (also referred to as a button of the second designated floor) corresponding to the second designated floor on the elevator floor selection keypad.

Wherein, the step T1 can be implemented by one or a combination of the following ways:

mode 1: as shown in fig. 10(a), a communication device 6a is provided in the elevator car, and when the mobile terminal 4 receives a third signal sent by the communication device in the elevator car, it is determined whether the intensity value of the third signal is greater than a certain proportion of the intensity value of the designated signal, for example, greater than a certain proportion of the intensity value of the second signal, and if so, it is determined that the mobile terminal 4 has entered the car of the target elevator object. The communication device 6a may here likewise be a bluetooth Beacon device. When the user got into the elevator, the signal of the outer bluetooth Beacon equipment of elevator also can weaken also be the second signal, and the signal of the bluetooth Beacon equipment in the elevator car then can strengthen. It can therefore be assumed that the user has entered the elevator car when the intensity value of the third signal is greater than a certain proportion of the intensity value of the second signal, i.e. of the designation signal. The proportional value can be determined according to the actual condition of the elevator and the installation positions of the two Bluetooth Beacon devices, and the proportional value can be larger than 100% and can also be smaller than 100%. Therefore, the ladder taking process is simpler.

The designated signal may also be other signals whose signal strength changes with changing distance.

The determination may be made by the mobile terminal 4 or may be made by the server apparatus 3.

Mode 2: the mobile terminal 4 determines a position signal through a positioning device in the car of the target elevator object, and confirms whether the mobile terminal 4 enters the car of the target elevator object according to the position signal; such as: the distance between the position and the car is 0 or less than a certain value.

Usually, GPS cannot be used for positioning in the car, and the positioning device can use a WIFI device or still use a Bluetooth Beacon device. The schematic diagram is shown in fig. 10 (a).

The determination may be performed by the mobile terminal 4 or may be performed in the cloud.

Mode 3: the mobile terminal 4 senses a human body step signal, and confirms whether the mobile terminal 4 enters the car of the target elevator object or not according to the step signal. The algorithm is similar to a pedometer, and through a gyroscope and a vibration sensor which are installed on the mobile terminal 4, the mobile terminal 4 can sense whether a user enters an elevator car or not, and because people can cause different vibration when entering the car compared with the vibration when walking on the ground.

Mode 4:

as shown in fig. 10(b), the second two-dimensional code presenting device 7a is provided in the elevator car, and the mobile terminal 4 can confirm that the mobile terminal 4 has entered the car of the target elevator object once scanning is completed by scanning the second two-dimensional code presented by the second two-dimensional code presenting device in the elevator car.

Mode 5:

as shown in fig. 10(c), the two-dimensional code scanning device 7b is provided in the elevator car, and the entry of the mobile terminal 4 into the car of the target elevator object is confirmed by a signal generated by the two-dimensional code scanning device installed in the car scanning the third two-dimensional code appearing on the mobile terminal 4. This approach may be referred to as "inverse scan two-dimensional code".

Seventh embodiment

The method in the embodiment is used for realizing the elevator scheduled use, so that the whole elevator taking process is not contacted and is not operated, and a user does not need to contact an elevator button and a mobile phone. Which comprises the following steps:

when a user wants to use a certain elevator, the APP can be opened in advance when the user does not arrive at the elevator position, the target elevator is searched in the APP (such as the number or other descriptions of the target elevator are input), after the target elevator is inquired, the elevator taking instruction format of the target elevator is downloaded from the cloud through the Internet, and the reservation is set in the APP. Through the elevator taking command format, the elevator taking can be set to be realized in a way that if the mobile terminal 4 arrives near the target elevator and is awakened by the target elevator, the elevator is automatically sent to realize the operation-free elevator taking, or if the mobile terminal 4 arrives near the target elevator and is awakened by the target elevator, the elevator is automatically sent to realize the operation-free elevator taking. The instruction includes information from which floor to which destination floor. Generally, the operation-free elevator is suitable for elevators which are frequently taken, such as residential elevators in homes, office elevators in offices, or elevators which are frequently visited in hospitals, libraries, shopping malls, and the like.

After reservation, when a user reaches a certain distance near a target elevator of a starting floor, the mobile terminal 4 receives a wake-up signal sent by the target elevator, the mobile terminal 4 automatically wakes up, automatically sends an elevator taking instruction to the elevator, automatically controls the elevator to light a call calling button, the elevator automatically reaches the floor, confirms that the user has entered an elevator car, automatically lights a floor selection button of a target floor, and sends the user to the target floor. This mechanism is implemented by only requiring a first Beacon device to be located near the elevator call buttons as in figure (9a) and a second Beacon device to be located as in figure (10a), and the modification to the elevator is not significant relative to the other embodiments.

The method of this embodiment may also be used for pre-authorizing a user. For an elevator with a pre-authorization mechanism, the floor where the user has authority to call, the elevator which has authority to use, and the floor which has authority to reach can be recorded in advance. When a user carries a mobile terminal 4 which is registered in the system and is preauthorized to reach the vicinity of an elevator which is authorized to take and is on the floor which is authorized to call, the mobile terminal 4 is automatically awakened, an elevator taking instruction is automatically sent to the elevator, the elevator is automatically controlled to light a call calling button, the elevator automatically reaches the floor, a floor selecting button of a target floor is automatically lightened after the user is confirmed to enter the elevator car, and the user is delivered to the target floor.

The above embodiments can be not only independently applied, but also organically combined together according to the field environment and the customer requirements, which supplement each other. The combination of the embodiments can be applied to places such as hospitals and banks, which have higher security level and can not be connected with external networks at will, and can also be applied to relatively quiet places such as cells and office buildings. One embodiment applies to calls and another to floor control.

Those skilled in the art will appreciate that all or part of the processes of the embodiments methods may be performed by a computer program, which may be stored in a computer-readable storage medium and executed to perform the processes of the embodiments methods. And the aforementioned storage medium includes: various media capable of storing program codes, such as ROM or RAM, magnetic or optical disks, etc.

The foregoing is a more detailed description of the invention in connection with specific/preferred embodiments and is not intended to limit the practice of the invention to those descriptions. It will be apparent to those skilled in the art that various substitutions and modifications can be made to the described embodiments without departing from the spirit of the invention, and these substitutions and modifications should be considered to fall within the scope of the invention.
