Description

Technical Field

[0001] This utility model relates to the field of infrared meter reading probe technology, and in particular to a magnetically attached fixed infrared meter reading probe device. Background Technology

[0002] The working principle of an infrared meter reader is based on the macroscopic thermal phenomenon of radiation from an object. That is, an object will continuously emit electromagnetic waves into the surrounding environment at a certain temperature, and the frequency of the waves will change as the temperature rises. When the digital dial in the meter reading window emits a specific infrared signal, the infrared meter reader can sense these signals, read the numbers, and convert them into a highly readable data format. The data is then uploaded to the back-end management system through relevant software to realize functions such as online meter reading and remote monitoring.

[0003] Infrared meter reading probes are the core component of infrared meter readers, specifically designed for collecting and reading electricity meter data. They utilize infrared communication technology between the meter reading window and the meter panel to accurately and quickly transmit meter readings to the backend processing system. However, many existing infrared meter reading probes are fixed with screws during installation, making installation and disassembly inconvenient. Furthermore, the connecting cables on the probes lack adequate protection, leading to wear and tear over time and affecting transmission stability.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] The main purpose of this utility model is to provide a magnetically attached fixed infrared meter reading probe device, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A magnetically attached fixed infrared meter reading probe device includes a first mounting base and a second mounting base. An infrared LED is inserted and fixedly installed in the first mounting base, and a strong magnetic ring is installed at the upper end of the first mounting base. A phototransistor is inserted and fixedly installed in the second mounting base, and a transmission line is fixedly installed at the upper end of the phototransistor. A connecting line is fixedly installed at the lower ends of the first and second mounting bases.

[0008] Preferably, a handle is fixedly installed on both the lower left and lower right sides of the first mounting base. Several locking blocks are fixedly installed on the inner wall of the first mounting base. A powerful magnet is fixedly installed at the lower end of the infrared LED. The powerful magnet is fixedly installed inside the first mounting base. The locking blocks and slots are the same size and correspond in position. The infrared LED emits a modulated signal, and the reflective strip or encoder on the meter reflects part of the infrared light. The receiver of the probe, i.e., the phototransistor, detects the reflected signal and converts it into an electrical signal. Then, the phototransistor transmits the electrical signal to the meter reader via a transmission line. The meter reader decodes the signal and converts it into a reading.

[0009] Preferably, a second handle is fixedly installed on both the lower left and lower right sides of the second mounting base. Several second-type locking blocks are fixedly installed on the inner wall of the second mounting base. A second-type powerful magnet is inserted and fixedly installed at the lower end of the phototransistor. The second-type powerful magnet is fixedly installed inside the second mounting base. The second-type locking blocks and second-type locking slots are the same size and correspond to each other in position. Installation is achieved through magnetic attraction, making the installation and disassembly of the device relatively convenient.

[0010] Preferably, a protective shell is fixedly installed on the outer surface of the connecting wire. By providing a protective shell on the outer surface of the connecting wire, the connecting wire can be protected, reducing wear and tear on the connecting wire.

[0011] Preferably, the phototransistor is electrically connected to an external meter reader via a transmission line.

[0012] Preferably, the protective shell is made of silicone.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, a slot is made on the iron casing of the meter reader to accommodate the transmission line. The transmission line is then connected to the meter reader through the slot, and the phototransistor is quickly attracted to the iron casing by the second strong magnet. Next, a corresponding opening is made on the door of the casing for the water or electricity meter to be recorded. The size of the opening is not only compatible with the infrared LED, but the infrared LED also aligns with the reflective strip or coding disc on the marking through the opening. Then, the infrared LED is attracted to the door of the opening by the first strong magnet, and the installation is done by magnetic attraction, making the installation and removal of the device convenient. In addition, when the door of the opening is made of plastic, a strong magnetic ring can be placed on the back of the door. The first strong magnet will attract the strong magnetic ring, allowing the infrared LED to be compatible with different door materials.

[0015] The meter emits a modulated signal via an infrared LED. The reflective strip or encoder on the meter reflects part of the infrared light. The receiver of the probe, i.e., the phototransistor, detects the reflected signal and converts it into an electrical signal. Then, the phototransistor transmits the electrical signal to the meter reader via a transmission line. The meter reader decodes the signal and converts it into a reading.

[0016] By providing a protective shell on the outer surface of the connecting cable, the connecting cable can be protected and the wear and tear on the connecting cable can be reduced. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-4 As shown, a magnetically attached fixed infrared meter reading probe device includes a first mounting base 1 and a second mounting base 2. An infrared LED 3 is fixedly installed inside the first mounting base 1, and a strong magnetic ring 6 is installed on the upper end of the first mounting base 1. A phototransistor 4 is fixedly installed inside the second mounting base 2, and a transmission line 5 is fixedly installed on the upper end of the phototransistor 4. A connecting line 7 is fixedly installed on the lower ends of the first mounting base 1 and the second mounting base 2. The phototransistor 4 is electrically connected to an external meter reader through the transmission line 5.

[0026] A handle 11 is fixedly installed on the lower left and lower right sides of mounting base 1. Several locking blocks 10 are fixedly installed on the inner wall of mounting base 1. A powerful magnet 12 is fixedly installed through the lower end of infrared LED 3. The powerful magnet 12 is fixedly installed inside mounting base 1. The locking blocks 10 and the slots 13 are the same size and correspond to each other. The infrared LED 3 emits a modulated signal, and the reflective strip or encoder on the meter reflects part of the infrared light. The receiver of the probe, i.e., the phototransistor 4, detects the reflected signal and converts it into an electrical signal. Then, the phototransistor 4 transmits the electrical signal to the meter reader through the transmission line 5. The meter reader decodes the signal and converts it into a reading.

[0027] A second handle 21 is fixedly installed on the lower left and lower right sides of the second mounting base 2. Several second locking blocks 20 are fixedly installed on the inner wall of the second mounting base 2. A second strong magnet 22 is inserted and fixedly installed at the lower end of the phototransistor 4. The second strong magnet 22 is fixedly installed inside the second mounting base 2. The second locking blocks 20 and the second locking slots 23 are the same size and corresponding in position. The installation is carried out by magnetic attraction, which makes the installation and disassembly of the device relatively convenient.

[0028] A protective shell 30 is fixedly installed on the outer surface of the connecting wire 7; the protective shell 30 is made of silicone. By providing a protective shell 30 on the outer surface of the connecting wire 7, the connecting wire 7 can be protected and the wear and tear on the connecting wire 7 can be reduced.

[0029] It should be noted that this utility model is a magnetically attached fixed infrared meter reading probe device. First, a slot adapted to the transmission line 5 is made on the iron box housing the meter reader is installed in. At this time, the transmission line 5 is connected to the meter reader through the slot, and the phototransistor 4 is quickly attracted to the iron box housing by the second strong magnet 22 on it. Next, a corresponding opening is also made on the door of the box housing of the water meter or electricity meter to be recorded. The size of the opening is not only adapted to the infrared LED 3, but the infrared LED 3 also corresponds to the reflective strip or code disk on the mark through the opening. Then, the infrared LED 3 is attracted to the door of the box housing through the opening by the first strong magnet 12. The device is installed by magnetic attraction, making the installation and removal of the device easy. Removal is relatively convenient. In addition, when the door with the opening is made of plastic, the strong magnetic ring 6 can be placed on the back of the door. At this time, the strong magnet 12 and the strong magnetic ring 6 will attract each other, so that the infrared LED3 can adapt to different door materials. When meter reading is required, the infrared LED3 emits a modulated signal, and the reflective strip or encoder on the meter reflects part of the infrared light. The receiver of the probe, namely the phototransistor 4, detects the reflected signal and converts it into an electrical signal. Then, the phototransistor 4 transmits the electrical signal to the meter reader through the transmission line 5. The meter reader decodes the signal and converts it into a reading. Finally, the meter reader uploads the data to the background management system through relevant software to realize online meter reading and remote monitoring functions.
