[0026] Please refer to Figures 1-8, a power data acquisition device for a base station: It includes a cabinet 1, one side of the cabinet 1 is provided with a cover plate 4, and the cover plate 4 is connected to the cabinet 1 by screws. A central processing unit is arranged in the cabinet 1. The central processing unit is connected with a metering module, the metering module is connected with a power transformer, the central processing unit is connected with a monitoring module, the central processing unit is connected with a storage module, the central processing unit is connected with a communication module, the central processing unit is connected with a display module, and the central processing unit is connected with a power supply module. The output end of the metering module is connected to the central processing unit. The power transformer is connected to the power data acquisition device by a pluggable terminal. The power transformer collects electrical characteristic parameters for 24 hours, transforms the collected signals for the sampled voltage and current signals, passes through a filter circuit, and filters to obtain an analog signal of 0 - 3V. After passing through the four processes of sampling, holding, quantization, and encoding by an A / D converter, it is converted into a digital signal. In the digital signal processing unit, calculations are performed through formulas to obtain the electricity consumption per second, which is accumulated, and finally the obtained electricity consumption value is transmitted to the central processing unit.

[0027] The monitoring module can identify abnormal states. 1. Remote signaling: AC voltage too high alarm, AC voltage extremely high alarm, AC voltage too low alarm, AC phase loss alarm, AC input power failure alarm, lightning arrester failure alarm, lightning arrester air switch off alarm, generator power generation status; 2. Remote measurement: equipment system time, line voltage Uab, line voltage Ubc, line voltage Uca, phase A voltage Ua, phase B voltage Ub, phase C voltage Uc, first - way phase A current Ia, first - way phase B current Ib, first - way phase C current Ic, zero - sequence current Io, first - way phase A active power Pa, first - way phase B active power Pb, first - way phase C active power Pc, first - way phase A reactive power Qa, first - way phase B reactive power Qb, first - way phase C reactive power Qc, first - way power factor PF, frequency F, first - way forward active electric energy, first - way forward reactive electric energy, first - way CT value, first - way PT value; 3. Remote control: used to start and stop the external standby power supply.

[0028] The storage module is used to store the data generated by the metering module and the monitoring module during the operation of the data acquisition device. The information is stored in a real - time storage mode. After the working power supply loses power, various historical data and set parameters should be permanently saved without loss. The historical data is automatically saved once at 0:00 every day by default, and the storage quantity of each item of data for each path (total active electric energy, total active power, three - phase current) is not less than 1000 pieces.

[0029] The central processing unit provides anti - theft power functions such as power factor, effective values of voltage and current, voltage - current phase angle, harmonic calculation, zero - line anti - theft power detection, automatic measurement of full - voltage loss with low power consumption, and open - circuit and short - circuit detection of secondary - side transformers.

[0030] The communication module is connected to the central processing unit and has both wireless and wired communication methods, including a 4G Internet of Things interface and an RS485 communication interface. It transmits the information of the power data acquisition device to the management platform.

[0031] The display module receives the display instructions transmitted by the central processing unit and displays the required data. It has working status indicators (including working, communication, and active power metering indicators) and fault indicators (such as phase sequence errors), and is used to show the power to the user. It can be switched through buttons to display and configure device parameters, and query real-time and historical data.

[0032] The power supply module starts to maintain the normal operation of the device after the mains power is cut off.

[0033] A number of partitions 6 are evenly arranged in the cabinet 1. The partitions 6 are used to place electronic components such as different modules. An exhaust component is provided at the bottom of the cabinet 1, which can discharge the high-temperature gas and dust inside the cabinet 1. A reciprocating lead screw 7 is provided at the top of the exhaust component. A lifting box 11 is fitted on the outer circumference of the reciprocating lead screw 7. The reciprocating lead screw 7 generally has two thread grooves with the same pitch and opposite helix directions, and the two ends are connected by a transition curve. When the reciprocating lead screw 7 rotates, the side of the helical groove pushes the slider placed in the helical groove to move axially back and forth. When the reciprocating lead screw 7 rotates, it will drive the matching lifting box 11 to slide up and down in the cabinet 1. The lifting box 11 is slidably connected to the cabinet 1. A cleaning and heat dissipation component is provided inside the lifting box 11, which can not only remove dust from the components inside the cabinet 1 but also dissipate heat synchronously.

[0034] The exhaust component includes a motor 9. The bottom of the motor 9 is connected to the cabinet 1. A connecting rod 17 is provided at the rear of the motor 9. When the motor 9 rotates, it drives the connecting rod 17 to rotate circumferentially. The connecting rod 17 is rotatably connected to a right-angle plate 10. The bottom of the right-angle plate 10 is fixed to the cabinet 1. A first bevel gear 14 is provided at the front of the connecting rod 17, and a first fan blade 18 is provided at the rear of the connecting rod 17. The connecting rod 17 drives the first bevel gear 14 and the first fan blade 18 to rotate. When the first fan blade 18 rotates, it will generate an air flow towards the rear side, which can blow out the hot air inside the cabinet 1. Two air intake grilles 2 are provided at the upper part of the cabinet 1. The air intake grilles can prevent foreign impurities from entering the inside of the cabinet 1. The two air intake grilles 2 are arranged symmetrically left and right. A baffle 5 is provided at the rear of the cover plate 4. The relatively cold air outside enters the inside of the cabinet 1 through the air intake grilles and is discharged through the baffle 5. When the air flow is discharged from the inside of the cabinet 1, it can blow up the baffle 5 to an inclined state. When heat dissipation is not required, the baffle 5 relies on its own gravity to return to the vertical state and fits against the rear side of the cover plate 4, which can prevent insects and moisture.

[0035] The top of the first bevel gear 14 meshes with the second bevel gear 15. When the first bevel gear 14 rotates, it drives the meshing second bevel gear 15 to rotate. A transmission rod 16 is provided at the top of the second bevel gear 15. The top of the transmission rod 16 is rotatably connected to the right-angled plate 10. The top of the transmission rod 16 is interconnected with the bottom of the reciprocating lead screw 7. The transmission rod 16 can drive the reciprocating lead screw 7 to rotate.

[0036] The cleaning and heat dissipation assembly includes a rack 8. The rack 8 is fixedly connected to the cabinet body 1. A driven gear 19 meshes with the front side of the rack 8. A transmission shaft 20 is provided on the right side of the driven gear 19. The transmission shaft 20 is rotatably connected to the lifting box 11. When the transmission shaft 20 moves along with the lifting box 11, the driven gear 19 will rotate under the action of the rack 8.

[0037] A number of driving bevel gears 23 are evenly arranged on the right side of the transmission shaft 20. The transmission shaft 20 drives the driving bevel gears 23 to rotate. Driven bevel gears 22 mesh with the front sides of the driving bevel gears 23. The driving bevel gears 23 drive the meshing driven bevel gears 22 to rotate. The driven bevel gears 22 are rotatably connected to the lifting box 11. A second fan blade 21 is provided at the rear side of the driven bevel gears 22, thereby driving the second fan blade 21 to rotate. When the lifting box 11 moves upward, the second fan blade 21 can be driven to rotate forward at this time, generating an air flow flowing forward, which can blow the components at the upper end of the partition board 6 and blow the dust on their surfaces. When the lifting box 11 moves downward, it will drive the second fan blade 21 to rotate in reverse, thereby generating an air flow flowing backward, which can adsorb the heat and dust of the components at the top of the partition board 6.

[0038] A regulating plate 12 is slidably connected to the front end of the lifting box 11. Two electric push rods 13 are provided on the outer side of the regulating plate 12. The two electric push rods 13 are arranged symmetrically left and right. The electric push rods 13 are interconnected with the regulating plate. The two electric push rods 13 can jointly control the height position change of the regulating plate 12. As Figure 5 shown, the regulating plate 12 covers most of the area of the front through hole of the lifting box 11 at this time. When the second fan blade 21 rotates, it is equivalent to reducing the size of the exhaust hole, increasing the flow rate of the air flow, and effectively cleaning the dust accumulated on the surface of the components. Then, as the lifting box 11 moves downward, the blown dust can be attracted backward and discharged through the exhaust assembly. In most cases, the electric push rods 13 will drive the regulating plate 12 to move upward without blocking the through hole of the lifting box 11, so as to increase the flow range of the air flow generated by the second fan blade 21 and enhance the heat dissipation effect. By intermittently controlling the telescoping of the electric push rods 13, the heat dissipation and dust removal of the components inside the cabinet body 1 can be realized.

[0039] A box body 3 is provided at the front end of the cabinet body 1. The box body 3 can be used for password verification, and then the device can be operated.
