Description

  The present invention relates to a door opening / closing frequency confirmation device that can easily grasp the number of times of opening and closing the door (the number of times the electric lock is used) without requiring mechanical wear or adjustment of a contact portion.

  Conventionally, in order to avoid the intrusion of suspicious people at the entrances and exits of rooms and entrance doors of general housing, apartment buildings such as condominiums, tenant buildings, hotels, etc. By inputting a specific locking / unlocking signal, for example, a driving means such as a motor or a solenoid is driven to electrically advance and retract the dead bolt, thereby locking and unlocking the lock. Also, this type of electric lock automatically opens and closes the deadbolt based on the user's predetermined operation when the door is opened, and automatically closes the deadbolt after a predetermined time (for example, several seconds) when the door is closed. A type that locks by protruding is generally used.

  By the way, when an operation failure occurs in the electric lock, it is difficult to determine whether the cause is an operation failure due to a wiring failure or a component failure in the apparatus, or an operation failure due to the lifetime of the durability. For this reason, it is important to accurately grasp the number of times the electric lock is used (≈the number of times the door is opened and closed). Therefore, in general, the number of operations of the electric lock (or the number of times of opening and closing the door) is counted by a mechanical counter in order to perform appropriate maintenance and replacement work before the endurance life of the electric lock.

  However, when such a mechanical counter is used, it must be installed so as to protrude from the door or door frame, and the design is impaired. In addition, problems such as failure due to aging may occur in the component parts of the counter, and there is a problem that reliability is lacking.

  Therefore, the mechanical counter having the above-described problems has hardly been actually used. As a result, the number of times the door was opened and closed could not be grasped, and sudden failures and malfunctions could not be prevented or prevented (predicted) when the frequency of use was higher than the number of times assumed by the manufacturer. Even when maintenance service is performed, the number of times that the electric lock is used (≈ the number of times the door is opened and closed) is not known, so that appropriate judgment and response cannot be taken.

  Therefore, the applicant of the present application can confirm the number of times of locking / unlocking operation without impairing the design, and can easily determine whether the cause of the malfunction is caused by the lifetime of the durability number. As a result, a device for detecting the number of times of locking / unlocking operation disclosed in Patent Document 1 below was developed.

FIG. 4 is a schematic configuration diagram of a locking / unlocking operation frequency confirmation device disclosed in Patent Document 1 below. As shown in the figure, the locking / unlocking operation frequency confirmation device 100 locks and unlocks the lock by moving the dead bolt 103 forward and backward with respect to the locking hole 102a of the strike 102 which is a lock receiver provided on the door frame 101 side. It detects the number of times of locking / unlocking of the locking mechanism 104. When the dead bolt 103 protrudes, it detects the protruding operation and outputs a detection signal, and counts the detection signal output from the detection unit 105. The counting display unit 106 displays the count value as the number of times of locking / unlocking operation of the locking / unlocking mechanism 104.

  Thus, in the locking / unlocking operation frequency confirmation device disclosed in Patent Document 1, the number of locking / unlocking operations is counted based on the detection signal when a dead bolt protruding when the electric lock is locked is detected. For this reason, there has been a possibility that the number of locking / unlocking operations cannot be accurately detected when mechanical wear or failure of the detection portion for detecting the protrusion of the deadbolt or poor contact occurs.

  Therefore, the present invention has been made in view of the above problems, and mechanical wear and adjustment of the contact portion are unnecessary, and the number of times the door is opened and closed (the number of times the electric lock is used) can be easily grasped. An object of the present invention is to provide a door opening / closing frequency confirmation device.

  In addition, about acquisition of the locking / unlocking information in the electric lock apparatus 20, an authentication method, and description and processing operation of each part which comprises the electric lock apparatus 20, such as drive control of a locking / unlocking mechanism, are the same as that of a general electric lock apparatus. Therefore, the description thereof is omitted.

  As shown in FIG. 2, the door opening / closing frequency confirmation device 1 of this example includes an acceleration detection unit 2, a storage unit 3, a display unit 4, a counting unit 5, an input / output unit 6, and a control unit 7 in a single housing. And is built in the electric lock device 20.

  The acceleration detection unit 2 connects a weight part with a thin beam part to a fixed part, and a piezoresistive element is provided in the beam part. When acceleration is applied to the weight part, the beam part bends and the weight part applies acceleration. It is composed of a piezoresistive acceleration sensor (uniaxial acceleration sensor) that electrically detects movement in the direction to detect the generation and magnitude of acceleration. The acceleration detection unit 2 detects a change in the resistance value caused by the distortion of the piezoresistive element generated by the acceleration generated when the door 10 is opened and closed, and converts the detected resistance value into an electric signal to open and close the door 10. Detect the resulting acceleration. And if the acceleration detection part 2 detects the acceleration according to opening / closing of the door 10, it will output the acceleration information based on this acceleration to the control part 7. FIG.

The storage unit 3 is composed of, for example, a magnetic or optical storage medium or a semiconductor memory such as a ROM or a RAM. The storage unit 3 stores opening / closing number information indicating the total number of times of opening and closing the door 10 output from the counting unit 5, various driving data for driving each unit of the door opening / closing number confirmation device 1, and the like. Incidentally, when storing the number of times of opening and closing information by storing in the storage unit 3 with the input date and time, it can be opened and closed history information even with this storing is.

  The display unit 4 is configured by a display device such as an LED, for example. When display control information corresponding to the number of times the door 10 is opened / closed is input from the control unit 7, the display content based on the control information is identified and displayed in stages (for example, The door 10 is opened and closed less than 100,000 times: blue, less than 150,000 to less than 150,000 times: yellow, and more than 150,000 times: red. In addition, as an installation position of the display part 4, it installs in the position which an operator can confirm at the time of a maintenance, and maintains a design property at the time of normal, and the clearance gap between a door frame and the door 10 is maintained. It is preferable that the display can be observed.

  The counting unit 5 counts the number of times door opening / closing information is input from the control unit 7 and outputs the counted value to the storage unit 3 as opening / closing number information. That is, the number of times the door opening / closing information counted by the counting unit 5 is input corresponds to the number of times the door 10 is opened and closed, and the number of opening / closing times output to the storage unit 3 indicates the total number of times the door 10 is opened and closed.

  The input / output unit 6 is for performing wired communication using, for example, a wired cable or wireless communication using infrared transmission / reception, for example, with a dedicated device 30 for information acquisition (such as a portable terminal capable of transmitting / receiving various types of information). Consists of various communication interfaces. For example, when the opening / closing frequency information is requested from the dedicated machine 30 operated by the operator during maintenance of the door 10 or the electric lock device 20, the input / output unit 6 is controlled by the control unit 7 and is stored in the storage unit 3. Is output to the dedicated machine 30.

  The control unit 7 is configured by a microcomputer such as a CPU, a ROM, or a RAM. The control unit 7 performs processing control for obtaining door opening / closing information from the acceleration information input from the acceleration detection unit 2, control for outputting the door opening / closing information to the counting unit 5, and the number of times the door opening / closing information is input by the counting unit 5. Control for counting, control for storing the number of times of opening / closing from the counting unit 5 in the storage unit 3, display contents corresponding to the total count of the number of times of opening / closing stored in the storage unit 3 (for example, the number of times of opening and closing the door 10 is 100,000 times) Less than: blue, less than 150,000 to less than 150,000 times: yellow, more than 150,000 times: red) control for outputting display control information to the display unit 4, and communication of the number of times of opening and closing performed with the dedicated machine 30 Each part which comprises the door opening / closing frequency confirmation apparatus 1, such as control, is integratedly controlled.

Here, processing control for obtaining door opening / closing information from acceleration information will be described. In general, the opening and closing operation of the door 10 is an opening and closing operation of the door 10. When the acceleration of the door 10 at the time of opening and closing is compared, in order to prevent the user from being caught in the door 10 when the door is closed, the door closer However, when the door is opened, the door 10 is opened by the user's will, so that the acceleration tends to be faster than when the door is closed.
Therefore, as a process control for obtaining the door opening / closing information from the acceleration information, for example, the following processing method 1 ) can be considered.

1) Since the open door and the closing is satisfied closing of the door 10 as a pair, determines that the door 10 for each different acceleration information by the acceleration detection unit 2 is detected twice has been opened and closed, the opening and closing of the door 10 In order to count what has been done, door opening / closing information is output to the counting unit 5. That is, it is determined that the door 10 has been opened and closed by detecting two different accelerations, that is, opening and closing.

  In each of the processing methods described above, in order to prevent erroneous detection as an acceleration generated when the door 10 is opened / closed when the door 10 vibrates or moves differently from the opening / closing operation due to, for example, an earthquake or mischief, The process which removes the noise component which can be considered to be the cause of this, or the adjustment process which gives a width to a threshold value is performed.

  Next, the processing operation in the door opening / closing frequency confirmation device 1 described above will be described. Here, as an example of the process for obtaining the door opening / closing information from the acceleration information, the case where the acceleration of the door 10 at the time of opening the door is detected and the number of times of opening / closing the door 10 is detected based on the acceleration information corresponding to the acceleration will be described as an example. To do.

  When the user unlocks the electric lock device 20 and opens the door 10, the acceleration detection unit 2 detects the acceleration generated when the door 10 is opened, and sends the acceleration information corresponding to the detected acceleration to the control unit 7. Output. The control unit 7 determines whether or not the input acceleration information is acceleration information when the door is opened. At this time, if the control unit 7 determines that the acceleration information is when the door 10 is opened, the control unit 7 outputs door opening / closing information indicating that the door 10 is opened / closed to the counting unit 5.

  The counting unit 5 counts the number of times the door opening / closing information is input from the control unit 7 and outputs the counted value to the storage unit 3 as opening / closing number information indicating the number of times the door 10 is opened / closed. And the memory | storage part 3 memorize | stores the opening / closing frequency information output from the counting part 5. FIG. Further, the control unit 7 outputs display control information to the display unit 4 to display the display contents based on the opening / closing frequency information, and performs identification display according to the opening / closing frequency of the door 10.

  Further, when performing maintenance of the door or the electric lock device 20, when the operator requests the opening / closing frequency information to the door opening / closing frequency confirmation device 1 via the dedicated machine 30, the opening / closing frequency information stored in the storage unit 3 is dedicated. To the machine 30.

  As described above, the door opening / closing frequency confirmation device 1 includes the acceleration detection unit 2 for detecting the acceleration generated when the door 10 is opened and closed, modularized and installed in the electric lock device 20, and the detected door. It is determined whether the door 10 has been opened or closed based on acceleration information corresponding to the acceleration at the time of opening and closing. When it is determined that the door 10 has been opened and closed, the number of times door opening / closing information indicating that the door 10 has been opened and closed is counted, and the number of times of opening and closing that is the counted number is stored as the number of times the door 10 has been opened and closed.

  That is, the door opening / closing frequency confirmation device 1 of the present example is configured to detect the number of times the door 10 is opened / closed by the acceleration detection unit 2 using an acceleration sensor instead of a conventional mechanical counter. For this reason, there is no fear that problems such as wear of the detection unit and contact failure of the detection unit occur, and maintenance is free, and the number of times of opening and closing the door 10 can be accurately detected. Then, depending on the number of times the objective door 10 is opened and closed, maintenance can be performed before the failure, and the customer's profit can be protected. In addition, the maintenance company can propose replacement according to the number of times of opening and closing by periodically reading the number of times of opening and closing the door 10.

  Furthermore, since the door opening / closing frequency confirmation device 1 is modularized in a single housing and built in the electric lock device 20, it can be installed without impairing the aesthetic appearance.

  In addition, display contents corresponding to the number of times the door 10 is opened and closed are identified and displayed stepwise on the display unit 4 based on the number of times of opening and closing. For this reason, not only the customer himself can grasp the maintenance time, but also the maintenance agent confirms the display content displayed on the display unit 4 when performing various maintenance such as maintenance inspection and parts replacement of the door and the electric lock device 20. Thus, the number of times the door 10 is opened and closed can be grasped, and appropriate maintenance corresponding to the number of times the door 10 is opened and closed can be performed.

  Furthermore, since the input / output unit 6 for performing communication with the outside is provided, when it is desired to obtain the detailed opening / closing frequency of the door 10, the detailed door is extracted by extracting the opening / closing frequency information using the dedicated machine 30. 10 times of opening and closing can be acquired, and can be handled as an important inspection item when the maintenance contract is executed.

  By the way, in embodiment mentioned above, although the example which modularized the door opening / closing frequency confirmation apparatus 1 and installed in the electric lock apparatus 20 demonstrated, it should just be a location which can detect the acceleration produced at the time of opening and closing of the door 10, For example, it can be provided in the components of the door 10 such as the door 10 main body, a door knob or a door closer.

  In addition, as an example of the lock provided on the door, the electric lock device 20 of the automatic locking type when the door is closed and the number of times of opening and closing the door 10 are substantially the same has been described as an example. The type of the electric lock device 20 such as the required electric lock device 20 is not particularly limited. Further, in addition to the electric lock device 20, as shown in FIG. 3, for example, a general lock unit 40 that artificially locks and unlocks a thumb turn or a cylinder lock provided on a door can also be employed.

  In this case, since the door opening / closing frequency confirmation device 1 cannot secure a power source necessary for driving, for example, a commercial power source (AC 100 V) is used as an external power source to supply power to each unit, or a predetermined power source for the door 10 It is necessary to provide a power supply unit 8 composed of a battery unit provided in the location and the door opening / closing frequency confirmation device 1.
