The present invention relates to an elevator signal detection system, and more particularly, to an elevator signal detection system enabling quick response by an administrator by detecting elevator operation information in case of emergency and transmitting the information to an out-of-car communication apparatus.

1 illustrates a conventional elevator drive control system.

In the conventional elevator driving system, the control panel 11 collects the elevator driving information from the elevator car 20 and the platform at the same time as the elevator driving control and performs the function of transmitting to the monitoring panel 31 and the like.

In addition, the monitoring panel 31 receives the elevator driving information from the control panel 11 and displays the corresponding information on its own display device and stores the information in a database, thereby enabling the administrator to search for the corresponding elevator driving information.

The elevator car 20 is provided with an emergency call device 21 and an in-car call device 23 interlocked therewith, and a main device 25 is provided separately so that the call device 23 and the disaster prevention room 30 or the guard room 35 are provided in the car. It performs a switching operation for the call connection between the extra-curricular communication device (33, 36) provided in the).

In addition to the machine room and the disaster prevention room 30, an extra-currency call device 33 is installed so that information can be smoothly exchanged in case of an emergency for elevator operation.

However, in the conventional elevator driving system, the in-car communication device 23 operates by inputting an emergency call signal. However, the conventional in-car call device 23 is operated completely separate from the entire elevator driving system except that it is linked to the emergency call signal input.

That is, in-car and out-of-car communication devices 23, 33, and 36 are connected to the main device 25 to exchange exhalation information previously stored in the DTMF signal to identify the exhalation when operating multiple elevators, but the operation control of the elevator is controlled by a control panel ( 11) and the elevator operation information is exchanged between the control panel 11 and the monitoring panel 31, and has a structure that operates independently without any relation to the intercom system.

However, the conventional elevator operating system of such a structure has the following problems.

In the conventional elevator driving system, the elevator driving information is detected by the control panel 11 and transmitted to the monitoring panel 31, and only when there is an administrator in the disaster prevention room 30, the elevator driving information is watched through the monitoring panel 31. There is a problem that can not confirm the elevator operating information in the guard room 36, or there is no way to notify the manager of the elevator operating status in the absence of the manager.

Therefore, the manager has a problem that it is difficult to properly respond to the situation because the manager can not confirm the operating state of the elevator except when the watch panel 31 can immediately watch.

Even when the emergency call device 21 operates, it is difficult to collect accurate information about the state of the elevator except for the explanation of the passenger, and the emergency call device 21 and the in-car communication device 23 do not operate normally. In case of emergency, emergency call becomes difficult.

In addition, the conventional in-car communication device 23 can be hooked up only by silent detection even when hooked up from the emergency room 30 or the out-of-door communication device (ie, interphone) 33, 36 of the guard room. It may be difficult to use the in-car communication device 23 according to a situation where passengers take a long time due to a long time.

The elevator signal detection system according to the present invention includes a main device 125 for performing a switching operation between an in-car call device 123, an out-of-car call device 133, 136, and an in-car and out-of-car call device 123, 133, 136. In addition, the control panel 111 for transmitting the elevator operation information to the main device 125, the signal detecting means for detecting the corresponding elevator lift operation information transmitted to the main device 125 and transmits to the extracurricular call device (133, 136), and the extra The communication device 133, 136 is provided with a notification device for notifying the elevator operation information.

Car elevator call device 123 of the present embodiment is installed inside the lift car 120, hooked off in conjunction with the operation of the emergency call button 121, the outside of the call device is automatically installed in the disaster prevention room 130 ( 133, 136, 138 are automatically dialed. At this time, the elevator manager or the guard of the guard room, etc. in response to the call signal by hooking off the off-call device (133, 136, 138) or pick up the handset is a call connection.

The claim of the present embodiment performs the switching operation for the call connection between the in-car call device 123 and the out-of-car call device 133, 136, 138, and enables a smooth call connection even when a plurality of in-car call devices or out-of-car call devices are connected.

The control panel 111 of the present embodiment is installed in the elevator machine room 110 and is electrically connected to the elevator car 120 and the platform to perform elevator operation control, and collect and manage elevator operation information. In addition, the control panel 111 of the present embodiment transmits the elevator operating information to the monitoring panel 131 installed in the disaster prevention room 130 so that the manager can monitor the elevator operating state through the monitoring panel 131.

Furthermore, the control panel 111 of the present embodiment transmits the elevator driving information to the main device 125 to enable the main device 125 to transmit the elevator driving information to the out-of-call communication devices 133, 136, and 138. To this end, the control panel 111 is provided with a DTMF generator for converting the elevator operation information into a DTMF signal and DTMF transmission means for transmitting the DTMF signal to the main device (125).

The signal detecting means provided in the main device 125 of the present embodiment transmits the elevator driving information DTMF signal for the corresponding unit in case of emergency to the extracurricular call device 133,136,138, and each extracurricular call device 133,136,138 demodulates the DTMF signal for operation. The information is displayed on its own display devices 133a, 136a, and 138a or transmitted to the manager in a voice message.

This is caused by an administrator such as when a passenger is trapped in an elevator operating system or when an emergency call button 121 is operated by a passenger, when there is a problem that interrupts normal operation of the elevator, or when an abnormality occurs in an emergency call system. If a prompt response is required, the elevator operation information is to be promptly delivered to the manager by voice or visual message.

Passengers often find it difficult to grasp the situation on their own in the event of an abnormality in the elevator. In this case, since it is only a case of conveying the information of the built-in (that is, the number of lifts in which wing) built in the in-car communication device 123, it is true that there is a great difficulty in promptly determining and responding to the situation. It was.

In addition, even if the elevator unit is known, the operating state of the elevator is possible only by watching the elevator operating information collected on the monitoring panel 131 or the like or by monitoring the internal situation of the elevator through CCTV, etc., except where the monitoring panel 131 is installed. The manager at the site is not able to grasp the operating condition of the elevator properly, so it is often difficult to respond quickly even when receiving a call from a passenger.

In order to solve these situations, the present invention is in addition to transmitting information on the lift unit (for example, unit 3 located in the 21 building as location information) to the outside call device 133, 136, 138. Elevator operation information such as whether the vehicle is stopped or not, power failure is detected and transmitted to the external call device.

As a result, the passenger can distinguish the emergency call due to a simple mishap, and the manager can grasp the emergency situation without having to watch the monitoring panel 131 in case a prompt response is required, such as a case where a passenger jamming stoppage is detected. do.

For this purpose, the out-of-door communication device 133, 136, 138 of the present embodiment is a DTMF demodulator for demodulating the elevator operation information DTMF signal transmitted from the main device 125, and display devices (133a, 136a, 138a) for extracting and displaying the elevator operation information. Or a speaker device for notifying by voice announcement.

The extracurricular call apparatus of the present embodiment includes a wireless telephone 138, and the wireless telephone is installed in the disaster prevention room, or the interphone connected to the disaster prevention room in a wired manner can be used in parallel with the wireless telephone 138 using the same number. Therefore, when the manager is temporarily absent, the elevator operation information DTMF signal is transmitted from the wired-connected intercom body to the wireless telephone (that is, the wireless interphone) carried by the administrator, and the administrator transmits the elevator operation information to the wireless telephone (138) before the call. It has a configuration that can be confirmed through the display device (138a) or the speaker.

In addition, even when there is no emergency call, the elevator operating information is automatically transmitted to the wireless telephone 138 in the event of an emergency, so that the manager can quickly respond.

When the in-car call device 123 is operated in conjunction with an emergency call by the in-car passenger, the manager can call off the out-of-car call device (including a wireless telephone) to talk to the passenger in the elevator. That is, the manager can initiate a call with the in-car call device 123 using an interphone or a wireless telephone (wireless interphone) in the disaster prevention room in case of emergency (included when the emergency call button is operated or the elevator abnormal signal is detected).

As shown in FIG. 8, the out-of-door communication device of the present embodiment has a configuration in which a specific control signal is generated through a key input device to transmit a claim value or directly to a control panel. To this end, each out-of-car communication apparatus is provided with a DTMF signal generating means and a means for transmitting a DTMF signal.

On the other hand, the extracurricular call device transmits this signal to the main device when a specific number (for example, a password) or a character or function key is input, and the claim value is decoded into a control signal and transmitted to the elevator control panel so that the control panel is reset or the elevator operates normally. Ensure that necessary actions are taken. In addition, the decoding of a signal including a signal for controlling the control panel transmitted from the out-of-door communication device may be performed by the control panel so as to control the operation of the control panel.

In addition, the control signal input may be directly input by a separate function key, by using a password composed of numbers, letters, or a combination thereof, or may be input through a previously stored text message.

In this embodiment, the signal detecting means exchanges DTMF signals with the in-car and out-of-door communication devices 133, 136, and 138 at regular intervals, and exchanges DTMF signals with the in-car and out-of-door communication devices 123, 133, 136, and 138 to determine whether the emergency call device is operating normally. Detect.

In the present embodiment, the signal detecting means includes a DTMF signal generator and a DTMF signal transmitting / receiving means, and compares the received DTMF signal with a reference value to detect the normal operation of the call device from time to time.

In addition, when an abnormal state of the emergency call system is detected (for example, when the response signal is different from the set value or there is no response signal), the detection result is transmitted to the external call device 133, 136, 138 to promptly check the emergency call device by the administrator. Make it possible.

The out-of-door call device 133, 136, 138 is provided with a notification device for delivering the detection result of the normal operation of the emergency call device to the manager, which is the same as the notification device for notifying the manager of the elevator operation information. That is, the notification device of the present embodiment may be a speaker for delivering an abnormal voice call device to the voicement or display devices 133a, 136a, and 138a for visual display.

In addition, the signal detecting means of the present embodiment, when the call is initiated between the in-vehicle call device 123 and the out-of-call call devices (133, 136, 138), and detects the hook-on state signal of the out-of-call call device (133, 136, 138) that is the other party of the call in the in-car call device Automatically hook on (123).

That is, the elevator in-car communication device 123 can start a call by operating the emergency call device 121, but it is difficult to terminate the call itself. That is, when the call is initiated by the in-car call device 123 hooked off by the operation of the emergency call device and the handset is started by the caller device 133, 136, 138, such as the disaster prevention room 130, the call receiver 133, 136, 138 put the handset or call The call can be ended by pressing the end button.

However, in the conventional emergency call system, the call is terminated when the passenger in the car cannot terminate the call and the call is not detected for a certain period of time due to the silence detection. If necessary, there is a problem that gives a great anxiety to the passenger, or the call is not terminated when the surroundings are noisy. In this embodiment, when the hook-up device (133, 136, 138) hook-on is detected, the in-car call device (123) is also automatically By hooking on, the passenger in the car can start a call at any time when a call is needed.

Signal detection means provided in the main device 125 of the present embodiment may be by the control unit of the main device (125). That is, the main unit 125 control unit detects whether the emergency call system and the in-car and out-of-door and out-of-door communication devices 123, 133, 136, and 138 normally operate according to a program stored in the main device memory, and detects whether the call is terminated at any time when the call is initiated. (133,136,138).

In addition, when the elevator abnormal signal is generated, it is possible to promptly respond to the administrator by transmitting the elevator operation information received from the control panel 111 to the out-of-call communication device (133, 136, 138) to display or notify by voice announcement.

That is, the controller of the main device 125 transmits the operation information converted into the DTMF signal for the exhalation elevator in which the abnormality received from the control panel 111 is transmitted to the out-of-door communication device 133, 136, 138 such as the disaster prevention room 130 or the guard room 135. Simultaneously with transmission, dialing to a remote call device such as a service center 150 enables rapid response.

In this case, the remote administrator can reset the elevator control panel or input the control signal necessary for normalizing the elevator operation through the remote communication device.In this case, the control signal input can be directly inputted with a separate function key, It is also possible to input a password composed of these combinations, and it is also possible for the signal detecting means to convert it into a decryption control signal and to transmit it to the control panel or to detect and decrypt a signal for controlling the control panel received at the remote communication apparatus from the control panel.

In another embodiment of the present invention shown in Figure 6, the control panel 111 does not transfer the elevator operation information to the main device 125, but to the corresponding exhalation machine room interphone 113. That is, the control panel 111 extracts the elevator driving information in case of emergency and converts the elevator driving information to a DTMF signal and transmits the same to the interphone 113 connected to the control panel 111.

In this embodiment, the interphone 113 connected to the control panel 111 transmits the elevator driving information converted into the DTMF signal via the claim value or directly to the out-of-car call apparatus 133, 136, 138.

In this case, it is also possible to use a conventional call line between the machine room interphone and the main device, and to transmit a signal by providing a data line separate from the call line, which is changeable according to an embodiment.

That is, since the former is rarely used for a call in a machine room interphone, it normally performs a function of receiving a control signal from a control panel and transmitting the signal to a main device, and in case of using a machine room interphone in the case of a machine room inspection, etc. It is possible to make it available for calling.

In addition, the latter means that a separate data transmission line can be established between the machine room interphone and the main device in order to more stably transfer the operation information of the elevator.

The out-of-door call device 133, 136, 138 demodulates the DTMF signal transmitted from the machine room interphone and displays it on the display devices 133a, 136a, 138a, or notifies the manager via voice speaker.

In another embodiment of the present invention shown in Figure 7, the elevator operation information is transmitted via the monitoring panel 130 via an interphone connected thereto or directly to the main device 125 or the outboard call device. Even in this case, the elevator driving information converted into the DTMF signal is transmitted to the out-of-call communication device 133, 136, 138 and displayed or notified to the manager as a voice message.

In another embodiment of the present invention, the transmission of elevator operation information and the transmission of various control signals between the control panel and the communication apparatus are transmitted by high frequency signals, not DTMF signals. That is, a communication method such as XDSL used for data communication is applied, and a device for modulating and demodulating it is installed in the control panel 111, the main device, and the out-of-car call device 133, 136, 138.

The following describes the operation of the elevator signal detection system of the preferred embodiment according to the present invention having the configuration as described above.

The signal detecting means periodically transmits DTMF signals to the in-car communication device 123 and the emergency call device according to the program stored in the memory (steps 200, 201, and 203).

Next, the DTMF signals generated and returned by these devices with respect to the transmitted DTMF signals are compared with the reference values to determine whether the internal and external call devices 123, 133, 136, 138 and the emergency call devices are operating normally (steps 205 and 207). .

If there is no signal conveyed due to disconnection of the line or the received signal is different from the set value, it is determined that the operation state is abnormal. In this case, the signal detecting means generates a DTMF signal of the corresponding information and transmits the DTMF signal of the corresponding information to the out-of-call communication apparatuses 133, 136, 138 and the monitoring panel 131 (steps 208 and 209).

The out-of-door call device 133, 136, 138 demodulates the received DTMF signal and displays a message on the display devices 133a, 136a, 138a indicating that an abnormality has occurred in the in-car call device 123 or the emergency call device. In addition, the speaker emits a voice message indicating that an abnormality has occurred in the specific call emergency call system through the speaker (210).

The manager receives the signal and takes action to make the emergency call system normal.

Next, the steps for controlling the call termination process are as follows.

According to the program stored in the memory of the present embodiment, the signal detecting means controller determines whether a call is initiated by an emergency call of a passenger (steps 211 and 212).

It is determined whether a predetermined time has elapsed after the call is started between the in-cabin call device 123 and the out-of-car call device 133, 136, 138 (S213).

When the predetermined time has elapsed, the signal detecting means control unit generates and transmits a DTMF signal for detecting the end of the call to the out-of-door communication apparatuses 133, 136, and 138 (steps 215 and 216).

The control unit detects the hook on / off state of the corresponding call device by comparing the DTMF signal returned from the out-of-call communication device 133, 136, 138 with the reference value (steps 217 and 218).

When the call device is in the hook-on state, the call device in the exhalation car is hooked on to allow the caller to re-send by the passenger or the manager (step 219).

The following describes an example of each step of signal detection means operation in case of emergency during elevator operation.

The elevator driving information DTMF signal is received from the control panel in the standby state (operation 230).

The signal detecting means, according to a program stored in the memory, when the passenger inputs an emergency call signal while using the elevator, or the elevator control panel 111 or the monitoring panel 131 determines that the stop failure or passenger trap has occurred as a result of detecting its own signal, the elevator When urgent action is necessary, such as when a fault signal is detected, the elevator driving information DTMF signal received from the control panel 111 is extracted and transmitted to the out-of-door communication device 133, 136, 138 (steps 233 and 235).

In addition, the signal detecting unit transmits the ring signal to the out-of-car communication apparatus in addition to transmitting the elevator driving information (step 237).

The out-of-door communication device 133, 136, 138 demodulates the DTMF signal of the received elevator driving information, displays it on the display devices 133a, 136a, 138a, and transmits the voice message to the manager through the speaker (step 238).

The manager checks the elevator operation information notified to the out-of-door call device 133, 136, 138, and can make a direct call with the passenger when there is an emergency call. Even when the manager is leaving the disaster prevention room 130, since the corresponding information is notified to the wireless telephone (wireless inter-phone) 138 possessed by the manager, the manager can immediately call the passenger by pressing a call button ( Step 239).

In addition, when an administrator is absent, the system can also be switched to a remote disaster prevention room, a service center, or the like automatically, so that a quick response by a remote service center can be performed.

When any one of the outside call devices 133, 136, 138 presses the call button or picks up the handset, the ring signal transmitted to the other outside call device is interrupted, and the main device 125 performs a switching operation so that the other exhalation elevator The emergency call by the in-car communication device 123 is switched to the standby state (step 251).

In addition, in the present embodiment, even when the passenger does not input the emergency call signal, if a signal requiring urgent action such as a passenger trapped failure is detected, the ring signal is transmitted to the out-of-car communication device 133, 136, 138 in addition to transmitting the elevator operation information. Is forwarded so that a call can be initiated between the manager and the passenger.

After checking the elevator operation information, the manager can input a signal for resetting the elevator control panel or input other control signals to the signal input device if it is determined necessary.

In this case, it is possible to send an urgent control signal to the main device even in a remote service center.

The signal detecting means receives these signals, decodes the input signal or password, converts them into control signals, and transmits them to the control panel. In the control panel, the signal detecting means receives and demodulates the DTMF signals received from the external communication device. It is also possible to operate in such a way as to reset to the control panel by switching to, and various methods can be applied according to the embodiment.

In another embodiment of the present invention, the elevator operation information is configured to be directly transmitted from the signal detection means provided in the control panel to the external car communication apparatus. To this end, the control panel comprises a DTMF generating means and a signal transmitting means for transmitting the DTMF signal to the elevator intercom system. Also in this case, the outside call device or the remote call device can directly transmit a signal for controlling the elevator control panel, and the control panel includes a means for receiving the corresponding DTMF signal from the outside call device and converting it into a control signal. The control panel is reset or the operation control of the control panel is performed based on the signal received from the control panel.

The scope of the present invention is not limited to the above embodiments, but is determined by the matters described in the claims, and it is obvious that the present invention includes various modifications and adaptations made by those skilled in the art in the same range as the matters described in the claims.

The elevator signal detection system of the present invention facilitates the maintenance check of the emergency call device by the manager because it checks the emergency call device and the call device inside and outside the car from time to time and transmits the corresponding signal to the call device outside the car. It allows for quick response in case of emergency and ensures the rescue of passengers in crisis.

In addition, since the elevator signal detection system of the present invention extracts and transmits the elevator operation information to the out-of-car communication apparatus at the time of detecting the elevator abnormal signal or detecting the emergency call signal, the manager is displayed or notified by voice announcement prior to the call with the passenger. It is possible to check the elevator operation information so that it can be quickly responded to, and it can be assured of the situation to passengers, etc., and can respond to mischief.

Furthermore, the elevator signal detection system of the present invention detects whether the call continues between the in-car call device and the out-of-car call device and hooks up the in-car call device when hooking on the call device. It allows you to respond quickly to urgent situations.

In addition, in the elevator signal detection system of the present invention, since the in-cabin call device employs a portable wireless interphone, it is possible to collect elevator operation information by an administrator from outside the management room, and in case of emergency, the call can be directly initiated with the passenger. Strengthen your response to emergencies.

In addition, since it is possible to directly reset the elevator control panel or perform the operation control in the out-of-door communication device or the remote communication device, it is possible to quickly respond to the case.
