Description

Technical Field

[0001] This utility model relates to the field of mining power information acquisition technology, specifically a modular intelligent meter reading terminal suitable for underground environments. Background Technology

[0002] In underground working environments such as mines, accurate measurement of energy consumption and resource usage is crucial. Given the large number and dispersed locations of meters in mining areas, mobile communication signals (GPRS / GSM / SMS / CDMA / 3G / 4G / 5G, etc.) are extremely poor in most surface locations. This is especially true underground, where mobile communication is unavailable and the complex, interconnected tunnels make traditional mobile signal-based smart meter reading systems unsuitable, thus requiring manual meter reading. Traditional manual meter reading typically involves staff visiting meters at the beginning or end of the month to manually read the meters. This method can only record basic data and is insufficient for recording detailed electricity consumption data. Furthermore, abnormal electricity usage necessitates on-site inspection and analysis by specialized personnel. Manual reading is also prone to errors and omissions. Therefore, we propose a modular smart meter reading terminal suitable for underground environments. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a modular intelligent meter reading terminal suitable for underground environments. Compared with traditional meter reading methods, it does not require manual recording, avoids the phenomenon of misreading or missing records, improves the accuracy of meter reading, and can record detailed electricity consumption data, which makes it easier for staff to analyze the electricity consumption and determine whether there are any abnormalities in electricity consumption, thus effectively solving the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular intelligent meter reading terminal suitable for underground environments, comprising an explosion-proof box, wherein a meter, a battery module, a processor module, and a memory module are respectively installed inside the explosion-proof box. The battery module, processor module, and memory module are all connected to an aviation socket located inside the explosion-proof box via aviation plugs. An explosion-proof door is hinged to the explosion-proof box, and a sealing gasket corresponding to the explosion-proof box is provided on the inner surface of the explosion-proof door. A locking device for locking the explosion-proof door is provided on the explosion-proof box.

[0005] As a preferred embodiment of this utility model, the inner surface of the explosion-proof box is provided with two positioning rods, and the two sides of the memory module are symmetrically provided with two positioning blocks corresponding to the positioning rods, and the side surface of the positioning blocks is provided with positioning holes.

[0006] As a preferred technical solution of this utility model, the inner surface of the explosion-proof box is provided with two elastic clamping plates. The two clamping plates are symmetrically arranged on both sides of the memory module, and the end of the clamping plate facing the memory module is provided with a wedge block for clamping the memory module.

[0007] As a preferred embodiment of the present invention, the memory module has a data transmission interface on its side surface, and an elastic band is provided on the side surface of the memory module and the upper side of the data transmission interface, with a dust plug for preventing dust from the data transmission interface at the end of the elastic band.

[0008] As a preferred embodiment of this invention, the side surface of the memory module is provided with a marking area.

[0009] As a preferred embodiment of this utility model, the locking device includes a rotating rod rotatably mounted on the side plate of the explosion-proof box, an elongated fixing block fixedly mounted at the end of the rotating rod, and an elongated through hole corresponding to the fixing block on the side surface of the explosion-proof door.

[0012] As a preferred embodiment of this utility model, two mounting blocks are symmetrically arranged on the upper and lower surfaces of the explosion-proof box, and mounting holes are provided on the side surfaces of the mounting blocks.

[0013] Compared with existing technologies, the advantages of this invention are as follows: By recording detailed meter data in the processor module and storing it separately in its built-in memory and memory module, staff can carry a portable data storage device such as a laptop or PDA when reading meters on-site. This device connects to the memory module via a data cable to download the detailed electricity consumption data for the current month from that meter. Compared with traditional meter reading methods, manual recording is unnecessary, avoiding errors and omissions, improving meter reading accuracy, and allowing for detailed recording of electricity consumption data. This facilitates staff analysis of electricity usage and identification of any abnormalities. The memory module is installed via an aviation connector. If data transmission takes a long time, it can be removed and used to transmit data to the portable data storage device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a modular intelligent meter reading terminal suitable for underground environments, including an explosion-proof box 1. The explosion-proof box 1 houses a meter 2, a battery module 3, a processor module 4, and a memory module 5. The processor module 4 can be a commonly used microprocessor with storage capabilities, such as a PLC controller or a microcontroller, preferably an 80C51 series microcontroller. The processor module 4 records detailed data from the meter 2 and stores it in its built-in memory and the memory module 5. When reading meters on-site, staff can carry a portable data storage device, such as a laptop or PDA, and connect it to the memory module 5 via a data cable to download the detailed electricity consumption data for the current month from the meter 2. Compared with traditional meter reading methods, this eliminates the need for manual recording, avoids errors and omissions, improves meter reading accuracy, and allows for the recording of detailed electricity consumption data, facilitating staff analysis of electricity usage and identification of any abnormalities.

[0021] The battery module 3, processor module 4, and memory module 5 are all connected to the aviation socket inside the explosion-proof box 1 via aviation plugs, ensuring circuit reliability. The memory module 5 is installed via aviation plugs; if data transmission takes a long time, it can be removed and used to transmit data to a portable data storage device. Simultaneously, staff can carry the memory module 5 to another nearby meter for data recording. Staff can plan their recording route based on the distribution of nearby meters 2, thus transmitting data while moving, greatly improving work efficiency.

[0022] When the staff removes the memory module 5, the data from the meter 2 is temporarily stored in the memory built into the processor module 4.

[0023] The battery module 3 is preferably a UPS (uninterruptible power supply) to maintain the normal operation of the meter 2, processor module 4 and memory module 5 and protect them from damage.

[0024] An explosion-proof door 11 is hinged to the explosion-proof box 1. Both the explosion-proof box 1 and the explosion-proof door 11 are made of thick steel plates and have explosion-proof function. The inner surface of the explosion-proof door 11 is provided with a sealing gasket 12 corresponding to the explosion-proof box 1 for moisture and dust protection, so that this meter reading terminal can be used in the complex environment underground.

[0025] In a preferred embodiment, two mounting blocks 18 are symmetrically arranged on the upper and lower surfaces of the explosion-proof box 1. The side surface of the mounting block 18 is provided with mounting holes 19. The explosion-proof box 1 is installed on the inner wall of the mine and fixed by means of screws or mounting rods passing through the mounting holes 19.

[0026] In a preferred embodiment, the inner surface of the explosion-proof box 1 is provided with two positioning rods 6, and the two sides of the memory module 5 are symmetrically provided with two positioning blocks 7 corresponding to the positioning rods 6. The side surface of the positioning block 7 is provided with positioning holes. The memory module 5 is fitted onto the positioning rods 6 through the positioning holes on the two side positioning blocks 7, which facilitates the accurate positioning of the memory module 5 by the staff during installation and connects its aviation plug to the corresponding aviation socket inside the explosion-proof box 1. The operation is simple and convenient.

[0027] In a further preferred embodiment, the inner surface of the explosion-proof box 1 is provided with two elastic clamping plates 10. The two clamping plates 10 are symmetrically arranged on both sides of the memory module 5. The end of the clamping plate 10 facing the memory module 5 is provided with a wedge-shaped block for clamping the memory module 5. When the memory module 5 is installed, the two wedge-shaped blocks and the clamping plates 10 are pushed outward. After the memory module 5 is installed in place, the clamping plates 10 are reset and clamped by the wedge-shaped blocks, ensuring the installation stability of the memory module 5. When it is necessary to remove the memory module 5, the ends of the two clamping plates 10 can be manually pushed outward to remove it.

[0028] In a preferred embodiment, the side surface of the memory module 5 is provided with a data transmission interface, which can be selected as a commonly used USB interface or a Type-C interface, for connecting with and transmitting data to devices carried by staff; an elastic band is provided on the side surface of the memory module 5 above the data transmission interface, and a dust plug is provided at the end of the elastic band to protect the data transmission interface from dust.

[0029] Optionally, an Ethernet signal module or a wireless transmission module, such as a commonly used Bluetooth module or Wi-Fi module, can also be installed in processor module 4. Workers can then connect to meter 2 wirelessly and transmit data. Workers do not need to read the meter on-site; they can connect to the storage module via the Ethernet signal module underground and download detailed daily electricity consumption data from that meter, subsequently uploading it to the server for statistical analysis.

[0030] In a preferred embodiment, the side surface of the memory module 5 is provided with a marking area 8, where paper with corresponding numbers or information can be pasted to facilitate the installation of the memory module 5 by workers to match the corresponding numbers and install it into the corresponding explosion-proof box 1.

[0031] In a preferred embodiment, the explosion-proof enclosure 1 is equipped with a locking device for locking the explosion-proof door 11. Specifically, the locking device includes a rotating rod 14 rotatably mounted on the side plate of the explosion-proof enclosure 1. An elongated fixing block 15 is fixedly mounted at the end of the rotating rod 14. The side surface of the explosion-proof door 11 has an elongated through hole 13 corresponding to the fixing block 15. When the explosion-proof door 11 is closed, the fixing block 15 rotates to a position coinciding with the through hole 13. After the explosion-proof door 11 is closed, the fixing block 15 protrudes to the outside of the through hole 13. At this time, rotating the fixing block 15 by 90 degrees can lock the explosion-proof door 11, which, together with the sealing gasket 12, plays a role in sealing and protection.

[0032] In a further preferred embodiment, a rotating handle 16 is fixedly provided on the outer surface of the fixing block 15. The rotating handle 16 is relatively thin, making it convenient for workers to grip and rotate the fixing block 15.

[0033] Optionally, a lock hole 17 is provided on the side surface of the rotating handle 16. After the explosion-proof door 11 is closed, a lock can be placed on the lock hole 17, so that the explosion-proof door 11 cannot be opened, thus preventing unauthorized personnel from opening the explosion-proof door 11 for operation and improving the security of the meter reading terminal.
