Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the invention relates to an alarm processing method which is applied to a five-party remote intercom terminal. The specific flow is shown in figure 1.
Step 101: and acquiring an alarm signal.
Specifically, an intercom button is arranged on a car intercom auxiliary machine in the elevator, when a user presses the intercom button for a long time (for example, presses 3S for a long time), an alarm signal is generated, and the five-party remote intercom terminal acquires the alarm signal. In practical application, after the car intercom auxiliary machine is triggered to generate an alarm signal, the alarm signal is transmitted to the machine room intercom main machine through the power line, and the machine room intercom main machine transmits the alarm signal to the five-party remote terminal.
Step 102: and detecting the current running state of the elevator, and judging the validity of the alarm signal according to the running state.
Specifically, after the five remote talkback terminals acquire the alarm signal, the alarm signal is not directly transmitted to an elevator manager, but the current operation state of the elevator is detected first, and the operation state of the elevator is used as a basis for judging the validity of the alarm signal. The specific judgment process is shown in fig. 2:
substep 1021: and judging whether the elevator stops running or not.
Specifically, the data of the running state of the elevator is obtained, and whether the elevator is in the running state or in the stopped state is judged according to the data of the current running state of the elevator. When the elevator is in a down state, substep 1022 is performed; when the elevator is in a normal operating state, substep 1024 is performed.
Substep 1022: and judging whether the car door is opened or not.
Specifically, the opening state data of the elevator car door is acquired, and whether the car door is opened or not is judged according to the opening state data of the car door. When the car door of the elevator is in an open state, executing a substep 1023; when the car door is in the closed state, the sub-step 1025 is performed.
Substep 1023: and judging whether the parking position is normal or not.
Specifically, the position data of the current stop of the elevator car is obtained, and whether the elevator car stops at the normal stop floor or the abnormal position between two floors is judged according to the position data of the current stop of the elevator car. When the elevator car stops at the normal stop floor, the substep 1025 is executed; when the elevator car stops at an abnormal position between two floors, substep 1024 is performed.
Substep 1024: and judging that the alarm signal is invalid.
Sub-step 1025: and judging that the alarm signal is effective.
As can be seen from the description of the substep 1021 to the substep 1025, the elevator stops and the car door is closed, the elevator stops and the car door is opened but stops at an abnormal position between two floors, and the two conditions belong to an abnormal operation state of the elevator, and at the moment, the alarm signal is judged to be an effective alarm signal; the elevator normally runs, the elevator stops and the car door is opened but stops at a normal stop floor, the two conditions all belong to the normal running state of the elevator, and the alarm signal is judged to be an invalid alarm signal at the moment. The alarm signal is judged by fusing the current running state of the elevator so as to further ensure the authenticity of the alarm signal and prevent false triggering.
It should be noted that the description of sub-step 1021 to sub-step 1025 is only for providing a feasible solution, and does not limit the specific implementation manner of the present invention.
Step 103: and selectively filtering the alarm signal according to the effectiveness of the alarm signal.
Specifically, when the five remote talkback terminals judge that the alarm signal is valid, the alarm signal is transmitted to an elevator manager so that maintenance personnel can carry out emergency rescue at the first time; and when the alarm signal is judged to be invalid, the alarm signal is filtered out and is not reflected, so that false triggering can be prevented, and waste of manpower and material resources is avoided.
In the embodiment, when the alarm signal generated by triggering the car interphone auxiliary of the elevator is acquired, the alarm signal is not immediately transmitted to the elevator manager, but the running state of the elevator is detected, and the effectiveness of the acquired alarm signal is judged by checking the current running state of the elevator. When the alarm signal is invalid, filtering the invalid alarm signal to prevent false alarm; and when the alarm signal is judged to be effective, the alarm signal is transmitted to an elevator manager. The alarm signal is judged by fusing the elevator running state information, so that the false triggering rate of alarm is effectively reduced, the waste of manpower and material resources is avoided to a certain extent, and the elevator running is effectively managed.
A second embodiment of the present invention relates to an alarm processing method applied to five remote intercom terminals in an elevator. The second embodiment is substantially the same as the first embodiment, and mainly differs therefrom in that: in the second embodiment of the invention, the power supply condition of alternating current commercial power for supplying power to the elevator is considered, when the alternating current commercial power is powered off, the elevator is stopped, and the five-party remote talkback terminal judges that the alarm signal is effective according to the power failure information of the alternating current commercial power; when the alternating current commercial power is supplied normally, the validity of the alarm signal is continuously judged according to the running state of the elevator. The validity of the alarm signal is analyzed by fusing the power supply state of the alternating current mains supply and the running state of the elevator, so that the authenticity of the alarm signal is further ensured, an elevator manager treats an alarm event in a timely manner and takes measures to deal with elevator faults in time.
In the present embodiment, an elevator remote management system used in the alarm processing method is shown in fig. 3: the five-party remote talkback terminal is connected with the machine room talkback host through a power line, the machine room talkback host is connected with the car talkback auxiliary machine through a cable, and after the car talkback auxiliary machine is triggered to generate an alarm signal, the machine room talkback host forwards the alarm signal to the five-party remote talkback terminal. The five-party remote talkback terminal is connected with the backup power supply to acquire an alternating current mains supply power-down signal, and is connected with the elevator main control board to acquire the elevator running state information. And the five remote talkback terminals are finally connected with the machine room router through the internet access to establish an interactive link with the cloud platform.
The alarm processing method in the present embodiment has a specific flow as shown in fig. 4:
step 201: and acquiring an alarm signal.
Specifically, an intercom button is arranged on a car intercom auxiliary machine in the elevator, when a user presses the intercom button for 3 seconds, an alarm signal is generated, and the five-party remote intercom terminal acquires the alarm signal. In practical application, after the car intercom auxiliary machine is triggered to generate an alarm signal, the alarm signal is transmitted to the machine room intercom main machine through the power line, and the machine room intercom main machine transmits the alarm signal to the five-party remote terminal.
Step 202: and judging whether the power supply is normal or not.
Specifically, the five-party remote intercom terminal acquires power supply state information of alternating current mains supply from the backup power supply, and judges the power supply state of the alternating current mains supply according to the power supply state information. When the ac mains supply is normal, step 203 is executed; when the ac mains supply is abnormal, step 204 is executed. The validity of the alarm signal is judged by fully fusing the power supply state of the alternating current mains supply and the running state of the elevator in the step, so that the problem that the validity of the alarm signal cannot be judged according to the running state of the elevator due to the fact that the running state of the elevator cannot be obtained due to power failure of the alternating current mains supply is avoided, the validity of the alarm signal is further ensured, and false triggering is prevented.
In practical application, if the situation of power failure of the alternating current mains supply is very short, the five-party remote intercom terminal immediately acquires the running state information of the elevator to evaluate the validity of the alarm signal again after detecting that the alternating current mains supply is normal in the time of causing danger to trapped people.
Step 203: and judging whether the elevator runs abnormally.
Specifically, the current running state of the elevator is detected, and when the running state of the elevator is abnormal, step 204 is executed; when the running state of the elevator is normal, step 205 is executed. The process of step 203 in this embodiment is the same as step 102 in the first embodiment, and the implementation manner has the same effect, and therefore, the description is omitted here.
Step 204: and judging that the alarm signal is invalid, and filtering the alarm signal.
Specifically, when the alarm signal is judged to be invalid, the false triggering is considered to occur, the five-party remote intercom terminal filters the alarm signal and does not respond, so that the false triggering can be prevented, and the waste of manpower and material resources is avoided.
Step 205: and judging that the alarm signal is effective, and processing the alarm signal.
Specifically, when the five-party remote talkback terminal judges that the alarm signal is effective, the alarm signal is subjected to digital processing to obtain alarm information and call information, and the five-party remote talkback terminal sends the alarm information and the call information to the cloud platform through a wireless route to establish real-time talkback communication between the cloud platform and the car interphone.
In addition, after the five-party remote intercom terminal uploads alarm information and conversation information to the cloud platform, real-time interphones of other positions in the five-party intercom system, such as car roofs, pits and machine rooms, can also be added to perform real-time intercommunication with the cloud platform, so that multi-party conversation is realized, multi-party personnel can be coordinated to participate in rescue in time, elevator faults can be dealt with in time, and user safety is guaranteed.
In practical application, five long-range terminals of talkbacking are distributed with the ID number that corresponds, the accessible ID binds corresponding elevator at the cloud platform, receive alarm information at the cloud platform after, can learn the identity information of elevator through the analysis to the ID number, with the direct detailed position information that provides trouble elevator to elevator maintenance personnel is accurate, effectively shorten stranded personnel's rescue time and elevator trouble speed of repaiying promptly, avoid appearing leading to the untimely problem of rescue because of stranded personnel are nervous or the unclear specific position information that can't provide the elevator of description.
In the embodiment, when the five-party remote intercom terminal acquires the alarm signal generated by triggering the car intercom auxiliary machine of the elevator, the alternating current mains supply power failure condition and the elevator running state information are subjected to fusion analysis, the validity authenticity of alarm information is further ensured, the false triggering rate of alarm is effectively reduced, the waste of manpower and material resources is avoided to a certain extent, the running of the elevator is effectively managed, meanwhile, the function of uploading the elevator fault condition to a cloud platform to inform relevant personnel under the condition that the machine room is not answered by people is realized, and therefore the safety of the elevator is improved.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
A third embodiment of the present invention relates to a five-party remote intercom terminal, as shown in fig. 5, including: an alarm signal receiving module 301, an elevator running state obtaining module 302, a main control module 303 and a network transmission module 304.
And the alarm signal receiving module 301 is configured to obtain an alarm signal, where the alarm signal is generated when the car intercom auxiliary of the elevator is triggered. The input end of the alarm signal receiving module 301 is electrically connected with the machine room talkback host, and when the talkback button of the car talkback auxiliary in the elevator is triggered to generate an alarm signal, the alarm signal receiving module 301 receives the alarm signal and transmits the alarm signal to the main control module 303.
The elevator state obtaining module 302 is configured to obtain current operation data of the elevator, and transmit the operation data to the main control module 303, so that the main control module can analyze the current operation state information of the elevator. Specifically, after the main control module obtains the alarm signal, the alarm signal is not immediately processed, but the elevator state obtaining module 302 is triggered to obtain the current operation state data of the elevator, so as to prevent false alarm.
And the main control module 303 is used for judging the validity of the alarm signal according to the current running state information of the elevator, and selectively filtering the alarm signal according to the validity of the alarm signal. The main control module 303 can judge the alarm signal by fusing the current running state of the elevator, so as to further ensure the authenticity of the alarm signal and prevent false triggering. Under the condition that the alarm information is judged to be effective, the main control module 303 processes the alarm signal and immediately transmits the alarm signal to an elevator manager through the network transmission module 304 so that maintenance personnel can carry out emergency rescue at the first time; under the condition that the alarm information is judged to be effective, the main control module 303 filters the invalid alarm signal, so that the false triggering rate of alarm is effectively reduced, the waste of manpower and material resources is avoided to a certain extent, and the effective management of the elevator operation is realized. In practical application, the MCU can be selected as a main control module to operate.
And the network transmission module 304 is used for providing a communication channel between the car interphone and the cloud platform when the main control module judges that the alarm signal is effective. When the master control module 303 judges that the alarm signal is effective, the alarm signal is processed, the alarm signal is converted into a network port digital signal and transmitted to the cloud platform, and after the cloud platform acquires the alarm signal, real-time talkback communication with the car auxiliary machine is established through the network transmission module 304, so that a user can realize real-time talkback without adopting a traditional dialing mode, the operation is convenient, and related personnel can be informed of the fault condition of the elevator under the condition that no person in a machine room answers.

It should be understood that this embodiment is an example of a terminal device corresponding to the first embodiment, and may be implemented in cooperation with the first embodiment. The related technical details mentioned in the first embodiment are still valid in this embodiment, and are not described herein again in order to reduce repetition. Accordingly, the related-art details mentioned in the present embodiment can also be applied to the first embodiment.

In addition, in order to highlight the innovative part of the present invention, elements that are not so closely related to solving the technical problems proposed by the present invention are not introduced in the present embodiment, but this does not indicate that other elements are not present in the present embodiment.
The fourth embodiment of the invention relates to a five-party remote intercom terminal. The fourth embodiment is substantially the same as the third embodiment, and mainly differs therefrom in that: in a fourth embodiment of the present invention, the alarm signal receiving module includes an analog signal isolating unit and an analog signal processing unit, so that a more accurate alarm signal is obtained for the main control module to perform analysis processing; in addition, a power failure detection module is additionally arranged, environmental factors of elevator operation are fully considered, and authenticity of an alarm signal is further guaranteed.
As shown in fig. 6, the five-party remote intercom terminal in this embodiment includes: an alarm signal receiving module 301, an elevator running state obtaining module 302, a main control module 303 and a network transmission module 304. The five-party remote intercom terminal provided in the embodiment can convert the analog signal of the existing five-party intercom device into a network digital signal and has an alarm filtering function, and has important significance in realizing effective real-time intercom of the car intercom auxiliary and the remote cloud platform.
The alarm signal receiving module 301 includes an analog signal isolating unit 3011 and an analog signal processing unit 3012. When the trapped person in the elevator pushes the talk-back button of the car talk-back auxiliary 100 for 3 seconds, the car talk-back auxiliary 100 generates an alarm signal and transmits the alarm signal to the machine room talk-back main 200, and the machine room talk-back main 200 transmits the alarm signal to the alarm signal receiving module 301. In this embodiment, the analog signal isolation unit 3011 is disposed between the machine room intercom host 200 and the analog signal processing unit 3012 for electrical isolation to ensure electrical safety; and by arranging the analog signal processing unit, the analog signals which are easily interfered by various noises are converted to obtain digital signals, so that the subsequent transmission and analysis are facilitated.
The elevator running state obtaining module 302 is connected to the elevator main control board 400, and is configured to obtain current running data of the elevator, and transmit the running data to the main control module 303, so that the main control module 303 can analyze the current running state information of the elevator. The elevator running state acquisition module 303 and the elevator main control board 400 and the elevator main control module 303 adopt a serial communication mode, the communication mode can save communication cost in long-distance communication, and programming is simple and easy to realize. In practical application, serial interfaces are arranged on the elevator running state acquisition module 302, the main control module 303 and the elevator main control board 400 so as to facilitate communication connection.
And the main control module 303 is used for judging the validity of the alarm signal according to the current running state information of the elevator and the power failure information of the alternating current mains supply, and selectively filtering the alarm signal according to the validity of the alarm signal. When the main control module 303 receives the alternating current mains supply power-off alarm signal transmitted by the power-off detection module, the main control module 303 judges that the alarm signal is invalid; when the main control module 303 does not receive the ac mains power failure signal, the main control module 303 then queries the current operation state of the elevator through the elevator operation state acquisition module 302. When the elevator stops and the car door is closed, the elevator stops and the car door is opened but stops at an abnormal position between two layers, and the two conditions belong to the abnormal operation state of the elevator, the master control module 303 judges that the alarm signal is an effective alarm signal; and the elevator normally runs, the elevator stops and the car door is opened but stops at the normal stop floor, and the two situations both belong to the normal state of the elevator, and at the moment, the master control module 303 judges that the alarm signal is an invalid alarm signal.
Under the condition that the alarm information is judged to be effective, the main control module 303 processes the alarm signal to generate alarm information and a call signal, and immediately transfers the alarm information and the call signal to an elevator manager through the network transmission module 304, so that maintenance personnel can perform emergency rescue at the first time. And under the condition that the alarm information is judged to be effective, the main control module 303 filters the invalid alarm signal, so that the false triggering rate of alarm is effectively reduced, the waste of manpower and material resources is avoided to a certain extent, and the effective management of the elevator operation is realized. The main control module 303 can judge the alarm signal by fusing the power supply state of the alternating current commercial power and the current operation state of the elevator, so as to further ensure the authenticity of the alarm signal and prevent false triggering.
In addition, in practical application, the five remote intercom terminals are allocated with corresponding ID numbers, and corresponding elevators can be bound on the cloud platform through the IDs. After the cloud platform receives alarm information, the identity information of the elevator can be obtained through analysis of the alarm information, detailed position information of a fault elevator can be directly provided for elevator maintenance personnel accurately, rescue time of trapped people and emergency repair speed of elevator faults are effectively shortened, and the problem that rescue is untimely due to the fact that the trapped people are nervous or the specific position information of the elevator cannot be provided without clear description is avoided. In addition, in the ordinary maintenance work, elevator managers can check the online condition of the elevator through binding the unique identity ID of the five remote talkback terminals, and upgrade and maintain the elevator remotely.
And the network transmission module 304 comprises an ethernet PHY and an ethernet interface, and is used for providing a channel for communication between the car intercom auxiliary unit and the cloud platform when the main control module determines that the alarm signal is valid. When the master control module 303 determines that the alarm signal is valid, the alarm signal is processed to generate alarm information and a call signal, the alarm information and the call signal are transmitted to the machine room router 600 in the form of a network port digital signal, and finally an interaction channel is established with the cloud platform 700. In practical application, the communication connection can also be established with the cloud platform in a wireless transmission mode.
The power failure detection module 305 is electrically connected to the backup power supply 500, and is configured to detect power supply change information of the ac mains after the main control module 303 obtains the alarm signal, and transmit the power failure change information to the main control module 303. Through the power failure information of the fusion alternating current commercial power, the environment factor of the running of the elevator is fully considered, the authenticity of the alarm signal is further ensured, and false triggering is prevented.
In practical application, after the alarm information and the call information are uploaded to the cloud platform by the five-party remote intercom terminal, the real-time intercom of the intercom at other positions in the five-party intercom system, such as a car roof, a pit and a machine room, can also be added to the real-time intercom with the cloud platform, so that multi-party call is realized, and multi-party personnel can be coordinated to participate in rescue in time. It should be noted that, the five-party remote intercom terminal in the embodiment has no requirement on the SIM card of the 4G router for the call function, and only the flow function needs to be activated, so that the communication cost can be greatly saved.
In the embodiment, the five-party remote intercom terminal can isolate, convert and analyze analog signals in the existing five-party intercom system, finally converts the analog signals into digital signals of an Ethernet interface, then is connected with a router of a machine room through a terminal network port, and finally establishes interaction with a cloud platform; the five-party remote talkback terminal can fuse the alternating current mains supply power failure information and the elevator running state information to selectively filter the alarm signal, effectively reduces the false triggering rate of alarm, avoids the waste of manpower and material resources to a certain extent, and achieves the purpose of effectively managing the elevator; meanwhile, the elevator fault condition is transmitted to the cloud platform to inform relevant personnel of rescue under the condition that no person in the machine room answers, so that the safety of the elevator is improved.
