Description

Technical Field

[0001] This utility model relates to the field of equipment inspection technology, and in particular to a convenient inspection device between equipment. Background Technology

[0002] With the rapid development of information technology, bank equipment rooms play a crucial role in banking systems, undertaking critical tasks such as data storage, processing, and transmission. The stability and security of the equipment in these equipment rooms directly impact the normal operation of banking services and data security. Therefore, regular inspections and maintenance of equipment rooms are of paramount importance.

[0003] During equipment room inspections and maintenance, operators typically carry equipment to inspect the rooms. However, in critical banking locations such as data center equipment rooms, where core equipment like server racks and servers are densely packed, current equipment room inspections at bank branches rely on manual methods or localized monitoring of certain equipment. This fails to provide a comprehensive understanding of the overall operating environment of the equipment rooms. Furthermore, the limited technical capabilities of grassroots branches hinder the timely detection of potential risks. Additionally, the existing inspection process requires the use of various devices, such as access control cards for access control, cameras for taking photos and recording videos, and manual system entry for inspection results, making all inspection operations cumbersome.

[0004] For example, the Chinese Patent Office published patent CN218770934U on March 28, 2023: a handheld inspection device, including an image acquisition module, a central processing module, a positioning module, a power supply module, an information transmission module, and a display and interaction module. The image acquisition module collects images of the power components of the line, and the images are transmitted to a backend server via the information transmission module for power component anomaly analysis to determine the integrity of the circuit. However, it only monitors the information of the power components of the line and cannot monitor the overall operating environment of the equipment. Furthermore, it requires storing and uploading videos or photos taken during the inspection process to a platform. If the lighting is insufficient, it requires taking photos or recording videos while under illumination, increasing the workload of the inspection personnel. Summary of the Invention

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0027] Example 1:

[0028] This embodiment is a convenient inspection device between equipment, and its overall structure is as follows: Figure 1 As shown, the device includes a main control unit 1, an NFC reader / writer 2, a sensor unit 3, a device operation display unit 4, a laser light 5, an infrared fill light 6, a SIM card 8, a TF card 9, an antenna 10, a power module, an encryption chip 14, a microphone 15, a speaker 16, a display screen 17, and a camera module 19. It features multiple functions including high-intensity illumination, video recording, photography, audio recording, voice intercom, WIFI / 4G full network compatibility / Bluetooth communication, and NFC card reading.

[0029] The power module includes a power supply 11, a voltage regulator module 18, a fuel gauge 12, and a charging detection circuit 13. The power supply is connected to the main control unit and the fuel gauge, the fuel gauge is connected to the charging detection circuit, the charging detection circuit is connected to the main control unit through a mini USB interface, and the voltage regulator module is connected to the power supply module and the main control unit.

[0030] The sensor unit includes an environmental detection sensor, a gyroscope, and an accelerometer. The accelerometer measures the linear acceleration of the inspection device, enabling it to sense changes in acceleration within three-dimensional space, such as acceleration, deceleration, and free fall. The gyroscope measures the rotational angular velocity of the inspection device, detecting changes in the rotational speed and angle of the object around various axes, such as tilting and flipping. Through the gyroscope and accelerometer, service center staff can obtain information about the inspectors' status during the inspection process, thus determining whether they are working diligently. For example, if the acceleration measured by the accelerometer is significantly greater than a threshold, it indicates that the inspectors are moving too fast, potentially leading to oversights.

[0031] Furthermore, accelerometers and gyroscopes are often used together to more comprehensively and accurately perceive the motion and attitude changes of inspection equipment. Accelerometers outline the static posture, while gyroscopes fill in the details of dynamic rotation. When inspectors quickly rotate the inspection device, the accelerometer produces errors due to inertial delay, which the gyroscope immediately fills in with angular velocity data; meanwhile, the cumulative error caused by gyroscope drift is continuously calibrated by the accelerometer's gravity vector. This complementary mechanism provides precise data support for the inspection device during positioning and imaging.

[0032] Environmental monitoring sensors include air sensors and temperature and humidity sensors. Air sensors are used to detect data such as smoke, dust particles, and harmful gases in the equipment room, while temperature and humidity sensors are used to detect temperature and humidity data in the equipment room. Because core equipment such as server racks and servers are densely packed in the equipment room, they generate a lot of heat during operation, and excessively high humidity can also cause damage to the equipment in the equipment room. Therefore, it is necessary to monitor the temperature and humidity in the equipment room.

[0033] In the above modules, the main control unit, power supply, encryption chip, and connecting cables between modules are integrated into a single housing. The main control unit is located above the power supply. The display screen, indicator lights of the device operation display unit, and microphone are all mounted on the front surface of the housing. The indicator lights of the device operation display unit are located below the display screen, and the microphone is located above the display screen. The speaker is mounted at the bottom of the housing, and the sensor unit is mounted at the top of the housing. A card slot is located on the right side of the housing for inserting SIM cards and TF cards. The camera module, NFC reader / writer, laser light, and infrared fill light are all mounted on the back of the housing. The camera module is mounted above the NFC reader / writer, located in the upper left corner of the back of the housing, while the laser light and infrared fill light are mounted below the camera module. The above installation method is only one installation method of the device-to-device convenient inspection device integrated into the housing provided in this embodiment. This embodiment mainly describes the circuit architecture of the device-to-device convenient inspection device and does not limit the appearance of the device, as long as it can be held handheld.

[0034] This embodiment provides a convenient equipment room inspection device, a handheld intelligent inspection device integrating the functions of various equipment. Inspection personnel can complete equipment room inspections with one hand. Addressing the shortcomings of existing inspection devices that cannot meet daily inspection needs, it integrates built-in air, temperature, and humidity sensors to collect data on temperature, humidity, smoke, dust particles, and harmful gases, comprehensively recording the environmental conditions of the equipment room. It features strong illumination and supplementary lighting functions, enabling clear image or video data acquisition without additional equipment. This solves the problem of convenient inspection, realizing intelligent daily inspection of equipment rooms, effectively reducing the workload of site personnel, compensating for professional deficiencies, and further improving the risk control level of equipment rooms in the site. Simultaneously, it can obtain the acceleration and angular velocity of the device during the inspection process through a gyroscope and accelerometer, providing accurate data support for the positioning unit, and can determine whether the staff is slacking off during the inspection based on the device's movement.

[0035] Example 2:

[0036] This embodiment, based on embodiment one, adds a GPS positioning module and an access control card module, providing a convenient inter-equipment inspection device. This embodiment is a convenient inter-equipment inspection device, and its overall structure is as follows: Figure 1 As shown, the device includes a main control unit 1, an NFC reader / writer 2, a sensor unit 3, a device operation display unit 4, a laser light 5, an infrared fill light 6, a GPS / BeiDou positioning unit 7, an access card module, a SIM card 8, a TF card 9, an antenna 10, a power module, an encryption chip 14, a microphone 15, a speaker 16, a display screen 17, and a camera module 19. It features strong light illumination, video recording, photography, audio recording, voice intercom, WIFI / 4G full network compatibility / Bluetooth communication, NFC card reading, and other functions.

[0037] For bank branches, in order to prevent unauthorized personnel from accidentally entering important equipment areas, access control systems are usually installed on the doors of equipment rooms. A paired access card is required to enter the equipment area. Current inspection devices do not have access card chips and require the use of a separate access card, which causes inconvenience for inspection personnel.

[0038] This embodiment includes an access control card module, which is associated with the access control system. During inspections, inspection personnel can log in and open the access control between devices according to their permissions without having to carry a separate access control card.

[0039] Furthermore, this embodiment includes a GPS positioning module. Service center staff can use the GPS positioning module to see which bank branch's equipment room the inspection personnel are currently inspecting, thus assigning inspection personnel to bank branches that haven't yet been inspected. Simultaneously, it can acquire the inspection personnel's inspection route, determine whether the inspection personnel have inspected all equipment in the current equipment room, and send a location signal when a fault is detected, enabling service center staff to immediately know which bank branch has the fault and thus assign maintenance personnel to that branch.

[0040] The power module includes a power supply 11, a voltage regulator module 18, a fuel gauge 12, and a charging detection circuit 13. The power supply is connected to the main control unit and the fuel gauge, the fuel gauge is connected to the charging detection circuit, the charging detection circuit is connected to the main control unit through a mini USB interface, and the voltage regulator module is connected to the power supply module and the main control unit.

[0041] The sensor unit includes an environmental detection sensor, a gyroscope, and an accelerometer. The accelerometer measures the linear acceleration of the inspection device, enabling it to sense changes in acceleration within three-dimensional space, such as acceleration, deceleration, and free fall. The gyroscope measures the rotational angular velocity of the inspection device, detecting changes in the rotational speed and angle of the object around various axes, such as tilting and flipping. Through the gyroscope and accelerometer, service center staff can obtain information about the inspectors' status during the inspection process, thus determining whether they are working diligently. For example, if the acceleration measured by the accelerometer is significantly greater than a threshold, it indicates that the inspectors are moving too fast, potentially leading to oversights.

[0042] Environmental monitoring sensors include photosensors, air sensors, and temperature and humidity sensors. Air sensors are used to detect data such as smoke, dust particles, and harmful gases in the equipment room, while temperature and humidity sensors are used to detect temperature and humidity data. Because core equipment such as server racks and servers are densely packed in the equipment room, generating a lot of heat during operation, and excessively high humidity can also cause damage to the equipment in the equipment room, it is essential to monitor the temperature and humidity in the equipment room.

[0043] This application provides a convenient equipment room inspection device, a handheld intelligent inspection device integrating various equipment functions. Inspection personnel can complete equipment room inspections with one hand. Addressing the shortcomings of existing inspection instruments that cannot meet daily inspection needs, it integrates built-in air, temperature, and humidity sensors to collect data on temperature, humidity, smoke, dust particles, and harmful gases, comprehensively recording the environmental conditions of the equipment room.

This solves the problem of convenient inspection, realizing intelligent daily equipment room inspections, effectively reducing the workload of branch personnel, compensating for professional deficiencies, and further improving the risk control level of branch equipment rooms. It integrates a communication SIM card. When a problem is detected during inspection, data analysis is used to list "Important Alarms," ​​"General Alarms," ​​and "Notification Alarms" according to risk level, notifying relevant personnel via SMS for timely and effective fault handling. It has equipment identification capabilities; by scanning the equipment label, the brand, serial number, purchase year, and maintenance status can be queried, providing repair information for faults discovered during inspections.
