Description

Technical Field

[0001] This invention relates to the field of substation engineering construction, specifically a substation on-site signature recognition terminal and its alarm method. Background Technology

[0002] As the construction of ultra-high voltage (UHV) power grids in China accelerates, the construction and management of UHV substations requires multiple signatures on on-site documents, including signatures from individuals in different units and positions. These signed documents are then compiled and stored by the construction management unit. Currently, the construction management unit cannot verify the authenticity of signatures on the documents, leading to difficulties in tracing project data later, unclear division of responsibilities, and hindering the sustainable development of the power grid.

[0003] Existing signature recognition technology requires transmitting multiple signatures for each document on-site to the system backend in the form of images for one-by-one recognition. Due to the large amount of signature data on-site at substations, with multiple signatures on each document and complex and diverse personnel signatures, taking photos of each signature individually can no longer meet the processing needs of large-scale signature images. Furthermore, if a signature that does not belong to the person is found on-site, it is impossible to notify the staff in a timely manner to retrieve and re-sign the completed signature confirmation form.

[0004] Therefore, a device is needed that can simultaneously recognize multiple signature photos and alert on-site staff to accomplish this task. Summary of the Invention

[0005] The purpose of this invention is to provide a substation on-site signature recognition terminal and its alarm method, which can recognize multiple signature documents while alerting to signatures that do not belong to the person, greatly improving on-site office efficiency and signature accuracy, and avoiding unclear division of engineering responsibilities.

[0006] To achieve the above objectives, the present invention employs the following technical solution:

[0007] The main structure includes a terminal body. The upper surface of the terminal body has several upward-facing grooves. Two first circular holes are respectively provided on the two sidewalls of one end of each groove. A connecting rod is fixed inside each first circular hole. A first slide rail is rotatably fitted onto the connecting rod. The bottom of the first slide rail near the connecting rod is arc-shaped. An opening is provided at the top of the first slide rail. A second slide rail is fitted inside the first slide rail. A camera is fixedly mounted at the top of the second slide rail. Cylindrical protrusions are respectively provided on both sides of the bottom of the second slide rail. The protrusions are elastically connected to the sidewalls of the second slide rail by springs. Second circular holes are symmetrically arranged on the two sidewalls of the first slide rail along its extension direction. A battery compartment is located at the bottom of the terminal body. A power switch and an identification switch are provided on the sidewalls of the terminal body. A control communication circuit board, a communication circuit, and a power circuit are located inside the terminal body.

[0008] Preferably, a through groove is provided at the bottom of the side wall away from the connecting rod in the groove, penetrating the side wall of the terminal body. A compression spring is provided in the through groove, and a button is fixedly provided at one end of the compression spring. The button passes through the through groove and is exposed on the outside of the side wall of the terminal body.

[0009] Preferably, the side wall of the first slide rail is provided with an elastic hook that cooperates with the through groove, and the length of the first slide rail is slightly less than the length of the groove.

[0010] Preferably, the groove has a plurality of slots arranged linearly along the extension direction of the groove, and a strip-shaped block is provided on the rear wall of the first slide rail, the strip-shaped block being rotatably connected to the side of the first slide rail near the opening.

[0011] Preferably, the control communication circuit board is equipped with a voice broadcast module.

[0012] Preferably, the communication loop uses a 4G / 5G module for data communication.

[0013] An alarm method for a signature recognition terminal in a substation includes the following steps:

[0014] S1: Collect on-site signatures;

[0015] S2: Compare the collected on-site signatures with the signatures in the background database;

[0016] S3: The voice broadcast module broadcasts the comparison results.

[0017] Preferably, the on-site signature collection specifically involves: using a camera to capture the on-site signature online.

[0018] Preferably, the step of comparing the collected on-site signatures with the signatures in the background database specifically involves: pre-entering the signature belonging to the individual into the background database, and then having the on-site collection terminal transmit the collected signature information to the background database for comparison via a communication loop set inside the terminal body.

[0019] Preferably, the voice broadcast module broadcasts the comparison results as follows: when the signature information collected on-site does not match the signature information entered in the background, a voice error is reported.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] To address the issue of numerous signatures per page in substation field documents, making individual scanning time-consuming and laborious, a substation field signature recognition terminal is proposed. This terminal features a mobile camera track, allowing for easy repositioning of the camera based on signature locations on the documents. This enables rapid scanning of multiple signatures, improving recognition efficiency. Furthermore, it provides voice alerts to on-site staff in cases where a signature does not match the actual signature, ensuring immediate identification of the responsible party and avoiding wasted time on secondary signatures.

[0032] Example: A substation on-site signature recognition terminal and its alarm method

[0033] like Figure 1-3 The main structure includes a terminal body. The upper surface of the terminal body has several upward-facing grooves. This attached diagram shows four grooves, but it is not limited to four; the number of grooves can be increased or decreased depending on the actual situation. Two first circular holes are respectively provided on the two sidewalls at one end of each groove. A connecting rod is fixed inside each of the first circular holes. The two ends of the connecting rod are respectively fixed into the two first circular holes. A first slide rail is rotatably fitted onto the connecting rod. The bottom of the first slide rail near the connecting rod is arc-shaped, and there is a gap between the bottom of the first slide rail and the end of the groove near the connecting rod. To allow the first slide rail to rotate around the connecting rod, an opening is provided at the top of the first slide rail. A second slide rail is fitted inside the first slide rail and can slide along the extension direction of the first slide rail. A camera is fixedly installed at the top of the second slide rail. To save camera... Considering cost and space requirements, this camera is a commercially available small camera. Cylindrical protrusions are provided on both sides of the bottom of the second slide rail. These protrusions are elastically connected to the sidewalls of the second slide rail via springs. Second circular holes are symmetrically arranged on both sidewalls of the first slide rail along its extension direction. When the second slide rail slides along the first slide rail, the protrusions engage with the second circular holes, locking the second slide rail relative to the first slide rail. To move the second slide rail, simply press the protrusions and slide the second slide rail. A battery compartment is located at the bottom of the terminal body, housing a removable lithium battery to power the entire terminal. A power switch and an identification switch are located on the sidewalls of the terminal body. A control communication circuit board, a communication circuit, and a power circuit are located within the terminal body.

[0034] A through groove is provided at the bottom of the side wall away from the connecting rod in the groove, penetrating the side wall of the terminal body. A compression spring is provided in the through groove, and a button is fixedly provided at one end of the compression spring. The button passes through the through groove and is exposed on the outside of the side wall of the terminal body. An elastic hook that cooperates with the through groove is provided on the side wall of the first slide rail. The length of the first slide rail is slightly less than the length of the groove. When the terminal completes the data collection, the first slide rail needs to be fixed to the terminal body. At this time, the second slide rail is slid to the bottom of the first slide rail, and then the first slide rail is rotated to place the elastic hook into the through groove, thereby locking the first slide rail and the second slide rail. When the terminal needs to perform a data collection operation, pressing the button will push the elastic hook out of the through groove.

[0035] The groove has several slots arranged linearly along its extension direction. A strip-shaped locking block is provided on the rear wall of the first slide rail. The strip-shaped locking block is rotatably connected to the side of the first slide rail near the opening. By rotating the strip-shaped locking block to engage with the slots in the groove, the first slide rail can be locked relative to the identification terminal body when it is in operation.

[0036] The control and communication circuit board is equipped with a voice broadcast module, and the communication circuit uses a 4G / 5G module for data communication.

[0037] An alarm method for a substation field signature recognition terminal includes the following steps:

[0038] S1: Collect on-site signatures;

[0039] S2: Compare the collected on-site signatures with the signatures in the background database;

[0040] S3: The voice broadcast module broadcasts the comparison results.

[0041] The on-site signature collection process specifically involves: using a camera to capture the signatures on-site online; comparing the collected on-site signatures with the signatures in the background database; pre-entering the signature belonging to the individual into the background database; and transmitting the collected signature information to the background database for comparison via a communication loop located within the terminal itself. The voice broadcast module broadcasts the comparison results specifically by issuing a voice error message when the on-site signature information does not match the signature information entered into the background database.
