[0002] The elevator five-way intercom system is an emergency call and fault assistance device inside the elevator. It is normally used in scenarios where passengers are trapped, elevator doors cannot be opened or closed, there is an emergency stop, or a fault alarm sounds, allowing passengers inside the elevator car to call the control room for assistance. According to the company's elevator safety management requirements, the user unit needs to inspect the elevators daily and conduct a test once a day. The operating procedure is as follows: Press the emergency call button inside the car; the control room should immediately ring / display a message with clear voice, no background noise, and no interruptions.
[0003] Problems and shortcomings of existing technologies: 1. When there are many buildings and a large number of elevators, labor costs increase significantly, requiring a large number of maintenance and on-call personnel. 2. Test records are not traceable, and it is easy for items to be missed during the testing process, making it impossible to guarantee 100% testing coverage. 3. Testing requires occupying the elevator car, which may lead to complaints from residents during peak hours. 4. Whether the call is clear, whether there is static or howling, etc., is entirely based on the tester's subjective judgment. Summary of the Invention
[0004] Based on this, a testing device for an elevator five-way intercom system is provided. This testing device helps save manpower and improves testing efficiency and accuracy.
[0005] The specific plan is as follows: A testing device for an elevator five-way intercom system includes: a control module, a callback module, a voltage detection module, and a recording and playback module. The voltage detection module is used to detect the voltage value on the system bus. The control module is used to determine whether to start timing based on the detection result of the voltage detection module. The callback module determines whether the intercom device needs to be activated based on the timing results from the control module. The recording and playback module is used to play the recorded audio information according to the control signal from the control module.
[0006] In one embodiment, a power supply module is also included, which provides operating voltage to the control module, the callback module, and the voltage detection module.
[0007] In one embodiment, When the voltage detection module detects that the voltage value on the system bus is lower than the set voltage value, the control module starts timing. When the voltage detection module detects that the voltage value on the system bus has recovered to the set voltage value, the control module stops timing.
[0008] In one embodiment, when the timing of the control module is less than a set time value, the callback module activates the intercom device.
[0009] In one embodiment, after the callback module activates the intercom device, the recording and playback module plays the recorded audio information.
[0010] In one embodiment, the elevator five-way intercom system test device is connected in parallel to the system bus via an optical isolator.
[0011] In one embodiment, the intercom device is an intercom device inside the car, an intercom device in the machine room, or an intercom device in the pit.
[0012] In one embodiment, activating the intercom device includes shorting the call button on the intercom device.
[0013] In one embodiment, the audio information played by the recording and playback module is transmitted to the central control room via an intercom device, and the central control room records the received audio information into an audio file and saves it.
[0014] A testing method for an elevator five-way intercom system, using the aforementioned elevator five-way intercom system testing device, specifically includes the following steps: S100, central control room intercom device S200: When the voltage detection module detects that the voltage value on the system bus is lower than the set voltage value, the control module starts timing. When the voltage detection module detects that the voltage value on the system bus has recovered to the set voltage value, the control module stops timing. If the timing time of the control module is less than the set time value, the callback module activates the intercom device. After the S300 callback module activates the intercom device, the recording and playback module plays the recorded audio information. The audio information played by the S400 recording and playback module is transmitted to the central control room via the intercom device. The central control room records the received audio information into an audio file and saves it. S500: Determine the test results based on the playback quality of the saved audio files.
[0015] The beneficial effects of this application are as follows: After applying the testing device of this application, operators are no longer required to enter the machine room, car, car top, and pit.

[0019] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0020] like Figure 1 As shown in the figure, an embodiment of this application provides a testing device for an elevator five-way intercom system. The testing device includes: a control module, a callback module, a voltage detection module, and a recording / playback module. The voltage detection module detects the voltage value on the system bus. The control module determines whether to start timing based on the detection result of the voltage detection module. The callback module determines whether to activate the intercom device based on the timing result of the control module. The recording / playback module plays recorded audio information according to the control signal from the control module. It also includes a power supply module, which provides operating voltage to the control module, callback module, and voltage detection module.
[0021] Specifically, such as Figure 1 As shown, the control module can be a microcontroller circuit. The callback module can be a callback circuit, the voltage detection module can be a voltage detection circuit, and the recording / playback module can be a recording / playback circuit.
[0022] In one embodiment, the voltage detection module is used to detect the voltage of the system bus. When the voltage detection module detects that the voltage value on the system bus is lower than the set voltage value, the control module starts timing. When the voltage detection module detects that the voltage value on the system bus has recovered to the set voltage value, the control module stops timing.
[0023] It should be noted that the elevator five-way intercom system has a two-wire bus, which serves as both communication and power supply lines. When in use, the system bus voltage is around 8V-11V, and when not in use, the system bus voltage is 18V.
[0024] The voltage setting is 18V. When the voltage detection module detects that the voltage on the system bus is lower than 18V, the control module starts timing. When the voltage on the system bus returns to 18V, the control module stops timing.
[0025] Based on the above, in one embodiment, when the timing of the control module is less than a set time value, the callback module activates the intercom device.
[0026] For example, if the set time is 3 seconds, and the time taken by the control module from the start of the timer to the stop of the timer is less than 3 seconds, the callback module will activate the intercom device. The purpose of activating the intercom device is to test it.
[0027] Specifically, if the intercom system in the car is equipped with the testing device described in this application, the central control room can dial the intercom system. At this time, the system bus voltage is approximately 8V-11V, less than 18V. When the voltage detection module detects that the voltage value on the system bus is lower than 18V, the voltage detection module outputs a low level. This low level triggers the control module to interrupt and start timing. When the voltage detection module detects that the voltage value on the system bus has returned to 18V, the control module stops timing. If this time is less than 3 seconds, it is determined that the intercom system needs to be tested, and the callback module activates the intercom system.
[0028] It should be noted that if the central control room dials the intercom device in the car and hangs up within 3 seconds, the timing time of the control module will be less than 3 seconds.
[0029] In one embodiment, activating the intercom device includes shorting the call button on the intercom device.
[0030] Specifically, the call-back circuit includes a resistor, an NPN transistor, and a 5V relay. Its working principle is as follows: the normally open contact of the call-back circuit is connected in parallel with the button on the intercom inside the elevator car. When the normally open contact of the call-back circuit closes, it is equivalent to pressing the call button on the intercom inside the elevator car.
[0031] Based on the above, in one embodiment, after the callback module activates the intercom device, the control module controls the recording and playback module to play the recorded audio information.
[0032] Specifically, the recorded audio information includes: "Elevator five-way intercom test begins in Unit XX, Building XX. Please leave your test message..." The specific audio information can be set according to specific needs. This audio information is pre-recorded and stored in the playback module. When playback is required, the recording and playback module directly plays this audio information.
[0033] Based on the above, the audio information played by the recording and playback module is transmitted to the central control room via an intercom device. The central control room records the received audio information into an audio file and saves it. After recording, the central control room can play the recording and judge whether the test is qualified based on the recording quality.
[0034] In one embodiment, such as Figure 2 As shown, the elevator five-way intercom system test device is connected in parallel to the system bus via an optocoupler isolator.
[0035] Specifically, since the device of this application can be connected in parallel to the system bus through an optocoupler during installation, the device of this application will not affect the normal operation of other mechanisms of the elevator five-way intercom system. The device of this application does not change the original structure of the elevator five-way intercom system, and only uses an optocoupler for detection. The recording and playback are completely isolated, making it safe and reliable to use.
[0036] In one embodiment, the intercom device is an intercom device inside the car, an intercom device in the machine room, or an intercom device in the pit.
[0037] Specifically, the testing device of this application can be installed in the intercom system inside the car, the intercom system in the control room, or the intercom system in the pit. This allows for testing of intercom systems in various locations.
[0038] Embodiments of this application also provide a testing method for an elevator five-way intercom system, employing the aforementioned elevator five-way intercom system testing device, such as... Figure 3 As shown, the specific steps include: S100, Central Control Room Intercom Device.
[0039] S200: When the voltage detection module detects that the voltage value on the system bus is lower than the set voltage value, the control module starts timing. When the voltage detection module detects that the voltage value on the system bus has recovered to the set voltage value, the control module stops timing. When the timing time of the control module is less than the set time value, the callback module activates the intercom device.
[0040] After the S300 callback module activates the intercom device, the recording and playback module plays the recorded audio information.
[0041] The recorded audio information played by the S400 recording and playback module is transmitted to the central control room via the intercom device. The central control room records the received audio information into an audio file and saves it.
[0042] S500: Determine the test results based on the playback quality of the saved audio files.
[0043] The method described in this application eliminates the need for operators to enter the machine room, car, car top, and pit. Testing of intercom devices in these locations can be performed remotely from the central control room. This method is highly efficient, fast, and convenient, significantly improving testing efficiency and accuracy while significantly reducing testing costs. Furthermore, after dialing a specific intercom device and hanging up within a designed time, the central control room can dial another intercom device. The recording mechanism in the central control room will automatically record the audio information transmitted from the corresponding intercom device, and so on, efficiently obtaining test audio from multiple intercom devices. The central control room can then analyze each recorded audio to determine the test results for the corresponding intercom device. Based on the test results, it can assess whether the intercom device is functioning properly. If the intercom device is malfunctioning, repairs can be performed.
[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
