[0033] As a common vertical conveying equipment, the bucket elevator is widely used in many fields such as mining, metallurgy, chemical industry and building materials. Among them, the efficient and stable operation of the bucket elevator is crucial for the continuity and reliability of the production process in various fields.
[0034] During the operation of the bucket elevator, the running speed of the bucket elevator is generally monitored by manual inspection to determine whether the bucket elevator is running normally, so as to realize the operation fault and hidden danger detection of the bucket elevator. However, manual inspection depends on experience and is prone to missed detection and misjudgment, so that the accuracy of the detected running speed is low. Therefore, how to improve the accuracy of the bucket elevator speed detection is an urgent problem to be solved.
[0035] To solve the above technical problems, the application provides a bucket elevator speed detection device and a bucket elevator control system.
[0036] Please refer to Figure 1 The application provides a bucket elevator speed detection device, which can include:
[0037] The following module is arranged on the rotating part of the bucket elevator and is used to follow the rotation of the rotating part.
[0038] The pulse generation module is used to generate a pulse signal according to the position of the following module, so as to obtain the speed detection result of the bucket elevator according to the pulse signal.
[0039] It should be noted that the application takes the bucket elevator as an example for illustration. Different types of bucket elevators have different transmission mechanisms, and different transmission mechanisms drive the corresponding transmission components to operate through different rotating components. The rotating component can include a belt tail wheel or a transmission sprocket.
[0040] It can be understood that the following module can be arranged at any position of the rotating component, and the pulse generation module is fixedly arranged towards the following module. During the operation of the bucket elevator, as the position of the following module changes, the pulse generation device can generate a pulse signal according to whether the following module is detected, so as to realize the rotation speed detection of the rotating component according to the period or frequency of the pulse signal, and obtain the speed detection result of the bucket elevator. For example, the following module is arranged on the transmission surface of the rotating component.
[0041] Therefore, the application provides a bucket elevator speed detection device. During the operation of the bucket elevator, the following module follows the rotation of the rotating part of the bucket elevator, and the pulse generation module generates a pulse signal according to the position of the following module, so as to obtain the speed detection result of the bucket elevator according to the pulse signal, thereby realizing the automatic detection of the running speed of the bucket elevator. Compared with manual inspection, the application does not have the problems of missed detection and misjudgment, and improves the accuracy of the bucket elevator speed detection.
[0042] In a feasible embodiment, the following module can include a magnetic piece or a light shielding piece.
[0043] Correspondingly, the pulse generation module can include any one of an electromagnetic induction switch, a Hall switch and a photoelectric switch.
[0044] It should be noted that the magnetic member can be a magnetic component or a magnet, and the position of the magnetic member can be detected by using electromagnetic principles.
[0045] In actual use, if the magnetic member is a magnetic component, the pulse generation module can be an electromagnetic induction switch. The magnetic component is arranged on the rotating component of the elevator, and the electromagnetic induction switch is arranged towards the magnetic component. When the magnetic component rotates with the rotating component, the magnetic field changes, and an induced electromotive force is generated in the induction coil inside the electromagnetic induction switch, thereby generating a pulse signal.
[0046] If the magnetic member is a magnet, the pulse generation module can be a Hall switch. The magnet is arranged on the rotating component of the elevator, and the Hall switch is arranged towards the magnetic component. When the magnet rotates with the rotating component and passes through the Hall switch, the output voltage of the Hall switch changes, thereby outputting a pulse signal.
[0047] In addition, the light shielding member can be a light shielding mark, and correspondingly, the pulse generation module can be a photoelectric switch. The light shielding mark is arranged on the rotating component of the elevator, and the photoelectric switch is arranged towards the light shielding mark. When the light shielding mark rotates with the rotating component, the light shielding mark periodically blocks the light path between the light source and the photoelectric detector in the photoelectric switch, so that the light signal received by the photoelectric detector is a pulse signal.
[0048] Therefore, the embodiment provides an elevator speed detection circuit. Only a magnetic member or a light shielding member needs to be arranged on the rotating component of the elevator, so that the speed detection of the rotating component can be realized. Compared with arranging an encoder or the like on the rotating component, the arrangement of the magnetic member or the light shielding member is simple and small in size, and the speed detection process of the elevator can be simplified.
[0049] In a feasible implementation, the elevator speed detection device can further include:
[0050] The protection switch module is connected with the pulse generation module and the feeder controller respectively, and is configured to output a switch signal to the feeder controller according to the pulse signal, so that the feeder controller controls the working state of the feeder according to the switch signal.
[0051] It should be noted that the protection switch module can output a switch signal to the feeder controller according to the pulse signal, so that the rotating speed of the rotating component of the elevator is transmitted to the feeder controller, so that the feeder controller controls the feeding, shutdown or adjustment of the operating parameters of the feeder according to the rotating speed of the rotating component, so as to realize the control of the working state of the feeder according to the pulse signal. The protection switch module can be a relay switch.
[0052] In an example, as shown in Figure 2 The pin 3 of the switching device 1SQ is connected with the live wire L11 through the circuit breaker QF2, the pin 13 of the relay switch 1KA is connected with the zero wire N, and the pin 14 of the relay switch 1KA is connected with the pin 4 of the switching device 1SQ, as shown in Figure 3 During the working process of the elevator, the switching device 1SQ detects the follow-up module, generates a pulse signal through the pin 3 and the pin 4 of the switching device 1SQ according to whether the follow-up module is detected, triggers the coil of the relay switch 1KA to act, thereby controlling the on-off state of the pins 11 and 12 of the relay switch 1KA, generating a switching signal, and outputting to the feeder controller 11EMB1, so that the feeder controller 11EMB1 can control the working state of the motor 11EM1 according to the received switching signal, so as to realize the control of the working state of the corresponding feeder.
[0053] Therefore, the embodiment provides an elevator speed detection device, which transmits the speed detection result of the elevator to the feeder controller through a relay, realizes the control of the working state of the feeder according to the speed of the elevator, ensures the safe operation of the elevator, and avoids equipment damage, material blockage or safety accidents caused by out-of-control speed.
[0054] In a feasible implementation manner, the elevator speed detection device can further include:
[0055] The acquisition module is connected with the pulse generation module, and is configured to acquire the pulse signal, and perform analog-digital conversion on the pulse signal to obtain the speed detection result of the elevator.
[0056] It should be noted that the acquisition module can acquire the pulse signal, perform analog-digital conversion on the pulse signal, and obtain the frequency, period and other digital quantities of the pulse signal as the speed detection result of the elevator. The acquisition module can include a data acquisition card or a data acquisition chip, etc.
[0057] In the embodiment, the acquisition module can include a data acquisition card.
[0058] It should be noted that the data acquisition card can automatically acquire the pulse signal, and send the speed detection result and the pulse signal to the upper computer for analysis and processing. The data acquisition card can use industrial Ethernet or wireless communication technology to upload the acquired data to the upper computer in real time.
[0059] In a feasible implementation manner, the elevator speed detection device further includes:
[0060] The central control module is connected with the acquisition module, and is configured to compare the received speed detection result with a preset speed range to obtain the running state of the elevator.
[0061] It should be noted that the central control module is composed of an industrial computer and can run a special speed monitoring software. The speed detection result sent by the data acquisition card is compared with a preset speed range to obtain the running state of the elevator, and it is determined whether the elevator is running normally. The running state can include a normal state and an abnormal state, and the preset speed range can be set according to the actual running requirements of the elevator.
[0062] In addition, the central control module can also use machine learning algorithms and pattern recognition techniques to learn historical speed detection results, historical running states and other historical data to improve the accuracy of the running state detection of the elevator.
[0063] In the embodiment, the central control module can include:
[0064] The human-computer interaction unit is configured to display at least one of the pulse signal, the speed detection result and the running state.
[0065] It can be understood that the speed detection software in the central control module can include a human-computer interaction interface. The central control module can display at least one of the pulse signal, the speed detection result and the running state by controlling the human-computer interaction unit to display the human-computer interaction interface of the speed detection software, which is convenient for users to monitor and manage.
[0066] In a feasible implementation, the central control module is further configured to perform audible and visual alarm and / or send alarm information to a user terminal when the running state is an abnormal state.
[0067] It should be noted that when the running state is an abnormal state, the elevator may have a running fault, and the central control module can perform alarm to remind the user to troubleshoot, etc.
[0068] It can be understood that the alarm mode can be to control the audible and visual alarm to perform audible and visual alarm, or to send alarm information to the user terminal to perform remote alarm, or to combine the audible and visual alarm and the remote alarm. The alarm signal can be a short message.
[0069] Therefore, the embodiment provides an elevator speed detection device. The pulse signal of the pulse generation module is collected by the data acquisition card and sent to the central control module to realize real-time monitoring of the speed of the elevator, timely discovery of speed abnormality, good integration with existing elevator control systems and equipment, seamless connection and collaborative work.
