Description

The present invention relates to a stop floor control system for an elevator .

  The so-called keyless entry system, which can unlock the electric lock device without using the unlock key, unlocks the actuator on the condition that the authentication ID of the authentication ID output from the portable device possessed by the user is authenticated. Some are configured to be locked and use passive transmission to output an authentication ID from the portable device to the authentication unit.

  Passive transmission is different from active transmission in which a user directly operates a portable device to output an authentication ID from the portable device to an authentication unit or an authentication ID receiving unit connected to the authentication unit. The authentication ID is automatically output to the passive transceiver in response to a response request signal output from the passive transceiver connected to.

  When such passive transmission is used in an environment where there are a plurality of portable devices around the same passive transmission / reception unit, authentication IDs from a plurality of portable devices that are simultaneously output in response to a single response request signal. As a reception system equipped with such a workaround, the one described in Patent Document 1 is known.

  In this conventional example, when the portable device receives a response request signal from the base station (passive transceiver device), it outputs an authentication ID at a different timing for each portable device and is received by the passive transceiver device. Avoid simultaneous reception.

  However, since the conventional example described above needs to set the response delay time as an eigenvalue for each portable device, it is necessary to determine in advance the passive transmission / reception device and the corresponding portable device. There is a problem of lacking.

The present invention has been made to eliminate the above drawbacks, and uses a portable device authentication ID receiving system that can accurately obtain authentication IDs from a plurality of portable devices without reducing versatility. The purpose is to provide a stop floor control system for the elevator .

According to the present invention, the object is
A portable device 2 that outputs an authentication ID for authenticating the locking and unlocking authority to the electric lock device 1;
A passive transmission / reception device 3 that transmits a response request signal that can be communicated with a group of portable devices 2;
An authentication unit 8 for authenticating the authentication ID of each portable device 2 acquired in the passive transmission / reception device 3;
After the residence floor is extracted from the control signal storage unit 10 that stores the authentication ID of the portable device 2 owner and the residence floor in association with each other, the stop floor control section of the elevator (E) uses the residence floor information as stop floor information. 11 and a control signal output unit 9 for automatically stopping the elevator (E) on the residence floor of the portable device 2 owner,
The portable device 2 transits between a response ready state in which a response signal is transmitted in response to reception of a response request signal from the passive transmission / reception device 3 and a response reject state in which no response signal is returned in response to the response request signal. Is possible,
And the said passive transmission / reception apparatus 3 receives only the strongest response signal of the receiving strength from the portable device 2 after outputting a response request signal at a predetermined interval, acquires the authentication ID in the response signal, and In response to the response request signal from the passive transmission / reception device 3, the mobile device 2 that has output the response signal having the strongest reception strength outputs a transition signal to the response reject state including the return time information to the response ready state, and the return time. This is achieved by providing a stop floor control system to the elevator that stops the response signal output from the portable device 2 for the time indicated by the information.

  In the present invention, when the response request signal output from the passive transmitting / receiving device 3 is received, the portable device 2 that outputs the authentication ID for authenticating the operation authority for the electric lock is provided with a response signal including the authentication ID. A request response unit 4 for outputting and a response stop control unit 5 for controlling output of a response signal from the request response unit 4 are provided. The response request signal output from the passive transmission / reception device 3 is a broad signal for communication with a relatively wide range of portable devices 2 such as manufacturers and sales areas, and the portable device that has received the response request signal from the passive transmission / reception device 3. 2 each simultaneously transmit a response signal including an authentication ID preset for each portable device 2.

  The passive transmission / reception device 3 receives only the response signal having the maximum reception intensity from among the response signals transmitted from the respective portable devices 2, and then enters the response rejection state with respect to the portable device 2 to be received. Outputs a transition signal. The portable device 2 that has received the transition signal to the response rejection state responds to the response request signal from the passive transmission / reception device 3 on and after the next cycle in order to stop outputting the response signal for the response request signal for a predetermined time. The passive transmitting / receiving apparatus 3 can sequentially receive the remaining portable devices 2 having the highest reception intensity.

  Therefore, in the present invention, it becomes possible to reliably acquire the authentication IDs of all the portable devices 2 existing in the communicable range with the passive transmission / reception device 3 without interference. In addition, it is not necessary to set response delay information or the like when the response request signal issued by the passive transmission / reception device 3 is received in the portable device 2, and it is possible to set a wide range by simply setting a response unit for the response request signal in common. ID acquisition of the portable device 2 by the passive transmission / reception device 3 becomes possible.

  Transmission of the transition signal from the passive transmission / reception device 3 to the portable device 2 can be realized by including the ID information specific to the portable device 2 set in advance in each portable device 2 in the transition signal, and the transition signal is received. Each portable device 2 stops outputting the response signal in response to the response request signal when the ID information in the transition signal designates its own station.

Although the ID information of the portable device 2 is also possible to separately set, it is also possible to use the authentication ID.

The portable device 2 is
A request responding unit 4 that outputs a response signal including an authentication ID in response to the response request signal output from the passive transceiver 3,
A response stop control unit 5 that stops transmission of a response signal from the request response unit 4 for a predetermined time when a transition signal to a response rejection state output from the passive transceiver 3 is received. it can.

Further, the passive transceiver 3 is
A request signal transmission unit 6 that outputs response request signals that can be received by a group of portable devices 2 at predetermined intervals;
From the response signal including a plurality of authentication IDs received within a predetermined time after the response request signal is output, only the maximum strength signal is acquired as an input signal, and a transition to the response failure state is made toward the portable device 2 that has transmitted the input signal. A stop signal output unit 7 that outputs a signal and stops the response to the response request signal from the portable device 2 can be configured.

  According to the present invention, it is possible to accurately acquire authentication IDs from a plurality of portable devices 2 without reducing versatility.

It is a block diagram which shows the apparatus control system of this invention. It is a block diagram which shows the detail of FIG. It is a timing chart of an equipment control system. It is a flowchart of a passive transmission / reception apparatus. It is a flowchart of a portable device.

  1 and 2 show an apparatus control system (Sc) of the present invention configured as a stop floor control system for an elevator (E) in an apartment house. This system is configured to sequentially read the authentication ID of the portable device 2 possessed by the passenger in the elevator (E) and automatically stop the elevator (E) on the residence floor of the portable device 2 owner. An authentication ID receiving system (Sr) for receiving the authentication ID from 2, an authentication unit 8 for authenticating the authentication ID acquired by the authentication ID receiving system (Sr), and a control signal output unit for the elevator (E) 9.

  The control signal output unit 9 outputs stop floor information to the stop floor control unit 11 that stops the basket 12 at a desired stop floor by operating the stop floor operation panel 13 disposed in the basket or the like on which the user gets. As shown in FIG. 2, it has a stop floor information generation unit 9b controlled by the control unit 9a and a control signal storage unit 10. The control signal storage unit 10 is a portable device for operating to unlock and unlock the electric lock device 1 of the arrival floor of the elevator (E) where the control signal output unit 9 is installed and the occupants of the arrival floor. The stop floor information generation unit 9b receives the authentication establishment signal from the authentication unit 8 and responds to the owner of the portable device 2 from the control signal storage unit 10 when the authentication ID of the device 2 is stored. After searching for the residence floor to be performed, it is output to the stop floor control unit 11 as stop floor information, and the basket 12 is stopped at the residence floor.

  The authentication ID receiving system (Sr) includes the portable device 2 and the passive transmission / reception device 3 described above.

  In this example, the portable device 2 is used to lock and unlock the electric lock device 1 installed on the door of each door, and is controlled by the control unit 2a to authenticate the operation authority for the electric lock device 1. It has ID storage part 2b which stores ID for authentication, and the lock / unlock operation button 2c for performing transmission operation to the electric lock apparatus 1 of authentication ID.

  In the electric lock device 1, the electric lock device 1 can transition between the locked and unlocked states of the door by controlling appropriate actuators, and the authentication ID transmitted from the portable device 2 is controlled by the control unit 1a. When authenticated in the unit 1b, the actuator is driven to perform transition drive between the unlocked and unlocked states.

  In addition to the so-called active mode by operating the locking / unlocking operation button 2c as described above, the locking / unlocking operation of the electric lock device 1 by the portable device 2 is based on the passive mode that does not require the user to operate the portable device 2. be able to. In order to enable operation in the passive mode, the electric lock device 1 is provided with a request signal transmission unit 1c that outputs a response request signal toward the portable device 2, and the portable device 2 includes a response including an authentication ID. A request response unit 4 that outputs a signal is provided. The request signal transmission unit 1c can be configured to always output a response request signal. However, it is possible to save power by using an appropriate operation such as detection by a human detection sensor or pressing of a request button by a user as an output trigger. You can also plan.

  Therefore, in this example, when the portable device 2 is brought within the communicable range with the response request signal while the response request signal is output from the electric lock device 1, the portable device 2 responds via the request response unit 4. A response signal is output in response to the request signal. The electric lock device 1 that has received the response signal from the portable device 2 extracts the authentication ID included in the response signal, performs an authentication operation in the authentication unit 1b, and performs a predetermined locking / unlocking operation when authentication is established. .

  Further, in this example, the request response unit 4 is a narrow-range response that outputs a response signal only in response to a response request signal from the electric lock device 1 that cannot be authenticated, with the correspondence relationship being determined in advance via the authentication ID. It is configured as a broad request response unit 4 that outputs a response signal in response to a response request signal issued by all the electric lock devices 1 having the same manufacturer, model or sales area, etc. The signal transmission unit 6 is also configured as a broad signal transmission unit that outputs a response request signal that can respond in addition to the portable device 2 paired in advance.

  As described above, when the electric lock device 1 and the portable device 2 communicate using the broad signal in the passive operation, the number of portable devices 2 that respond to the response request signal from the electric lock device 1 increases. Since there are many opportunities for signal collision and the like, the electric lock device 1 avoids the above problem by selecting and taking in only the signal having the strongest signal strength among the received response signals by the gate unit 1d.

  On the other hand, the passive transmission / reception device 3 includes a request signal transmission unit 6 that outputs a response request signal similar to the request signal transmission unit 1c arranged in the electric lock device 1 described above, and a gate unit 3b, and has an elevator (E ).

  The request signal transmission unit 6 can be configured to be activated at all times in accordance with the operation of the elevator (E) or to be activated when an appropriate sensor detects that a user has been on the basket. Yes, after activation, a response request signal is output at a predetermined time interval (t_req).

  The response signal from each portable device 2 in response to the response request signal is taken in only the signal having the maximum signal intensity via the gate unit 3b, and then the authentication ID included in the response request signal is sent to the ID acquisition unit 3c. It is stored and notified to the authentication unit 8.

  The passive transmission / reception device 3 is provided with a stop signal output unit 7, and the portable device 2 is provided with a response stop control unit 5. When the authentication ID is stored in the ID acquisition unit 3c, the stop signal output unit 7 generates a transition signal (stop signal) to the response failure state including the acquired authentication ID, and outputs it to the portable device 2. The output signal from the stop signal output unit 7 is a broad output that can be communicated with each portable device 2 in the same manner as the output signal from the request signal transmission unit 6, and each portable device 2 that has received the stop signal is included in the stop signal. It is confirmed whether or not the authentication ID matches the authentication ID of the local station, and if the match is confirmed, the response stop control unit 5 is notified of receipt of the stop signal. Upon receiving the stop signal, the response stop control unit 5 stops outputting the response signal from the request response unit 4 for a predetermined time.

  FIG. 3 shows an operation sequence of the device control system (Sc). The passive transmission / reception device 3 transmits a response request signal at a predetermined timing (t_req) in the activated state. As described above, the response request signal is output as a broad signal that can be communicated with each other even if each dwelling unit, condominium building, condominium installation area, and the like are different.

  When the portable device 2 within the communication range receives the response request signal, the portable device 2 transmits the response signal in response to each response request signal and is received by the passive transmission / reception device 3. The reception intensity of the response signal in the passive transmission / reception device 3 is increased in order of increasing proximity to the reception antenna (not shown) of the passive transmission / reception device 3 due to the influence of attenuation or the like in the space. Are selected and taken in, and the ID acquisition unit 3c extracts the authentication ID.

  FIG. 3 shows that the response signal (Sres_1) to the first response request signal (Sreq_1) is the largest from the portable device 2B with the authentication ID 2 surrounded by a thick line, and the authentication ID is obtained. The passive transmission / reception apparatus 3 generates a stop signal at the stop signal output unit 7 and transmits the stop signal to each portable device 2. The stop signal includes the authentication ID (2) of the portable device 2B, and the portable device 2 that has received the stop signal determines whether or not the authentication ID included in the stop signal is that of its own station. If the local station is addressed to the name, the response stop control unit 5 of the portable device (in this case, portable device 2B) sets the stop flag from “OFF” to “ON”, and is in the “ON” state. Is held for a predetermined time (t_stp) set in advance.

  The portable device 2 is configured to transmit a response signal only when the stop flag is “OFF”. As a result, the portable device 2B is applied from the passive transmission / reception device 3 until the stop flag is inverted to “ON”. The output of the response signal corresponding to the request signal is stopped.

  In addition, the passive transmission / reception device 3 that has acquired the authentication ID from the response signal (Sres_1) from the portable device 2 outputs the authentication ID to the authentication unit 8, and the authentication unit 8 authenticates the authentication ID. The authentication ID is output to the signal output unit 9. Upon receiving the authenticated authentication ID, the control signal output unit 9 searches the control signal storage unit 10 for the authentication ID, and outputs a control signal including stop floor information to the stop floor control unit 11 of the elevator (E) upon discovery. Thus, the passenger can be added to the stop floor without operating the stop floor operation panel.

  Further, when the acquired authentication ID is not authenticated by the authentication unit 8 as in the response signal (Sres_2) to the second response request signal (Sreq_2), it is not a resident of the apartment house or the elevator (E) Since it is considered that the resident does not have a dwelling unit on the destination floor, no stop floor information is output.

  After that, when an appropriate number of response request signals (Sreq_r) are output in the same procedure, the output of the response signals from the portable device 2 is regulated in descending order of reception strength, so the previous response request signals (Sreq_r (rk)), the response signal (Sres_ (rk)) whose reception level was not maximum becomes the maximum reception level, and the authentication ID is acquired. As a result, the authentication IDs of all portable devices 2 are acquired. The

  The holding time (t_stp) of the “ON” state of the stop flag may be set in advance in the portable device 2, or the transmission request timing (t_req) of the response request signal, the capacity limit of the elevator (E), etc. It is also possible to include the value in the stop signal and transmit it from the control signal output unit 9.

  FIG. 4 shows an operation flow of the passive transceiver 3. In the activated state, the passive transmission / reception device 3 outputs a response request signal at a time interval of (t_req), and at the start of the control, first, the timer for measuring the response request signal transmission timing has not timed out. If the time is up, a response request signal is transmitted from the request signal transmission unit 6 (step P2), and a response signal from the portable device 2 is awaited.

  Thereafter, when a response signal from the portable device 2 is received (step P3), the ID acquisition unit 3c extracts the authentication ID from the response signal (step P4), and outputs the authentication ID to the stop signal output unit 7 ( Step P5). Upon receiving the authentication ID, the stop signal output unit 7 generates and transmits a stop signal including the authentication ID (step P6), and then starts a timer that measures the timing of response request new signal transmission (step P7). .

  On the other hand, as shown in FIG. 5, the portable device 2 first detects whether or not the timer for measuring the set time of the stop flag has expired when the control is started (step M1). If it is, the stop flag is reset (step M2). If the time is not up, reception of the signal is waited without inverting the stop flag (step M3).

  When the signal received in step M3 is from the passive transmission / reception device 3 (step M4), it is determined whether or not the stop flag is in the set state (step M5). After the response signal is transmitted in the reset state (step M5) M6), return to the starting point of the control routine, and when in the set state in step M5, return to the starting point of the control routine without transmitting a response signal.

  On the other hand, if the received signal is not a response request signal in step M4, it is determined whether or not the received signal is a response stop signal (step M7). In order to determine whether or not the authentication ID included in the response stop signal matches that of the own station (step M8), and if the match is confirmed, a timer is started (step M9). ), A stop flag is set (step M10), and the control point is moved to the start point of the routine.
