Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a block diagram of an intelligent monitoring terminal of a base station oil engine according to an embodiment of the present invention, where the intelligent monitoring terminal may be disposed on a power distribution cabinet of a base station. Referring to fig. 1, the intelligent monitoring terminal 100 includes: a detection module 110, a main control module 120 and a wireless communication module 130 based on NB-IOT (Narrow Band-Internet Of Things). Wherein,
the detection module 110 is connected to a base station oil engine (not shown in the figure), and is configured to detect a power supply parameter of the base station oil engine to obtain a power supply parameter value; the power supply parameter values may include parameters such as starting time of power generation, ending time of power generation, power generation duration, three-phase current values, three-phase voltage values, power generation amount, oil engine frequency, active power, reactive power, apparent power and power factor.
The wireless communication module 130 includes a positioning module (not shown in the figure) for collecting the position information of the intelligent monitoring terminal;
the main control module 120 is connected with the detection module 110 and the wireless communication module 130;
the main control module 120 is configured to obtain a power supply parameter value and location information, and upload the power supply parameter value to a server of an operator based on an NB-IOT cloud platform through the wireless communication module 130, so that the server determines a regulation and control policy of oil engines corresponding to different base stations according to the power supply parameter value of the oil engines of different base stations.
For example, in this embodiment, the number of the detection modules is multiple, and the detection modules are respectively used for detecting different power supply parameters of the oil engine. The plurality of detection modules may include a voltage detection module, a current detection module, a frequency detection module, and the like. The detection modules can be connected with the oil engine respectively through oil engine connection terminals in the monitoring terminal and are used for directly detecting power supply parameters such as power generation voltage, power generation current and power generation frequency of the base station oil engine. After the detection module collects the power supply parameter value of the oil engine, the power supply parameter value of the oil engine can be sent to the main control module.
For example, the intelligent monitoring terminal of this embodiment may further include a commercial power connection terminal, and the plurality of detection modules may further perform detection on a plurality of power supply parameters of the commercial power through the commercial power connection terminal, for example, may detect a commercial power current, a commercial power voltage, and a commercial power incoming call or power off. After the detection module collects the power supply parameter value of the commercial power, the power supply parameter value of the commercial power can be sent to the main control module.
For example, in the intelligent monitoring terminal provided in this embodiment, the main control module may be connected to the multiple detection modules through an SPI (serial peripheral Interface) bus, and is configured to obtain multiple power supply parameter values detected by the multiple detection modules, and upload the multiple power supply parameter values to the server through the wireless communication module, so that the server determines the regulation and control strategies of the oil engines corresponding to different base stations according to the power supply parameter values of the oil engines of different base stations.
The intelligent monitoring terminal and the operator Internet of things cloud platform server realize remote communication through the wireless communication module. Preferably, the wireless communication module in this embodiment adopts a narrowband internet of things NB-IOT module, and the main control module can be connected with the NB-IOT module by a serial port. Specifically, the NB-IOT module includes a built-in NB-IOT communication protocol stack, an eSIM (Embedded-SIM) card, an antenna, and the like. Through the NB-IOT module, remote wireless communication between the intelligent monitoring terminal and the server can be realized. Meanwhile, the wireless communication module has the characteristics of low power consumption and wide coverage, so that the server can monitor the power supply information of a plurality of base stations in real time, the monitoring of the oil engine distribution points of the base stations in large batch is realized, for example, the technical characteristic of registering and logging on 5 ten thousand intelligent monitoring terminals based on NB-IOT can be supported, the monitoring of the oil engine distribution points of the base stations in large batch by operators is ensured, and the phenomenon that the oil engines generate electricity due to human factors is avoided. In addition, by using an NB-IOT PSM (deep sleep mode) power saving mode, the data are uploaded regularly every day, the number of times of daily information interaction with the cloud end is reduced, and the power consumption of the oil engine monitoring terminal of the base station can be saved.
For example, when monitoring of a base station oil engine is realized, an operator based on an NB-IOT cloud platform server may send a power supply parameter value acquisition instruction to an intelligent monitoring terminal according to operation information of a user, and after a main control module in the intelligent monitoring terminal acquires the power supply parameter value acquisition instruction through a wireless communication module, a detection module may be controlled to execute a detection operation of a power supply parameter. After the main control module obtains the power supply parameter value detected by the detection module, the power supply parameter value can be uploaded to an NB-IOT (NB-IOT) based cloud platform server by an operator, so that the server can monitor the power supply information of the base station oil engine.
Optionally, the main control module may also be configured to send the detection instruction to the detection module at regular time, for example, the main control module may be configured to send the detection instruction to the detection module at the same time every day, so as to implement the regular detection of the power supply to the base station.
Optionally, after the master control module obtains the power supply parameter value, the power supply parameter value is uploaded to the NB-IOT cloud platform-based server of the operator, and the power supply parameter value may be stored in a memory of the detection terminal for subsequent query. Specifically, the storage of the power supply parameter value may be performed by taking the storage frequency as a unit, and when the space occupied by the stored data reaches the maximum storage capacity, the data exceeding the storage capacity may be stored in a manner of overwriting the data stored first.
In this embodiment, after receiving the power supply parameter value, the operator may display the power supply parameter value and may perform certain analysis processing on the power supply parameter value based on the NB-IOT cloud platform server. For example, the power generation characteristics of the oil engine in a certain area, such as the number of power generation times, the power generation time, the power generation amount, the oil consumption and the like, can be calculated according to the power supply parameter values. The calculation result of the server can help an operator to preliminarily know the power supply information of oil engines of different base stations in a certain area. The area where the oil engine is located and the specific position information of the oil engine in the area can be acquired through a Global Positioning System (GPS) positioning module in the intelligent monitoring terminal and uploaded to the server. Preferably, in this embodiment, the GPS positioning module adopts a GPS and base station CELL/ID (CELL ID) combined positioning mode, the monitoring terminal can acquire CELL/ID information of the base station when the oil engine generates power and send GPS positioning information, and the server can determine the position of the power generation base station according to the acquired positioning information.
Further, based on the above calculation results, the server may perform secondary analysis on the calculation results, for example, may sort the generated energy, the generated time length, and the generated times of the oil engine in a certain area, and output a statistical table. In addition, the server can also determine the regulation and control strategy of the oil engine according to the power generation characteristics of the oil engine, for example, a suggestion that the position of the oil engine with the oil consumption higher than a set threshold value is arranged in an area with low power-off times of the commercial power can be provided, so that the oil engine resources can be reasonably utilized, and the waste of energy is avoided.
The intelligent monitoring terminal of the base station oil engine provided by the embodiment of the invention comprises a detection module, a wireless communication module and a main control module which is simultaneously connected with the detection module and the wireless communication module. Through setting up detection module, can detect the power supply parameter of base station oil engine, obtain the power supply parameter value. The main control module is used for acquiring the power supply parameter values and uploading the power supply parameter values to the server through the wireless communication module, so that the server can acquire the power supply information of the oil engines in real time, and can determine the regulation and control strategies of the oil engines corresponding to different base stations according to the power supply parameter values of the oil engines of different base stations. By adopting the technical scheme, the monitoring terminal automatically uploads the oil engine power generation data, false uploading of human factors to the oil engine power generation data is avoided, the accuracy of oil engine power generation monitoring is improved, and monitoring management of base station power generation is enhanced. Compared with the monitoring mode of power generation of the base station oil engine provided by the prior art, the technical scheme of the embodiment of the invention omits an FSU with higher manufacturing cost, and realizes the remote transmission of the power supply data of the base station by utilizing the remote communication between the operator based on the NB-IOT cloud platform server and the monitoring terminal, thereby achieving the effect of performing point distribution monitoring on a large batch of base station oil engines.
Example two
Fig. 2 is a block diagram of a structure of an intelligent monitoring terminal of a base station oil engine according to a second embodiment of the present invention, where the function of the intelligent monitoring terminal is optimized based on the second embodiment, and explanations of terms that are the same as or correspond to the second embodiment are not repeated herein. Referring to fig. 2, the intelligent monitoring terminal 200 provided in this embodiment includes: the system comprises a detection module 210, a main control module 220, a wireless communication module 230, a base station power distribution cabinet connecting terminal 240, an oil engine connecting terminal 250 and a commercial power connecting terminal 260. Wherein,
the detection module 210 is connected with the base station oil engine through the oil engine connection terminal 250, and is used for detecting power supply parameters of the base station oil engine to obtain power supply parameter values;
the main control module 220 is connected with the detection module 210 and the wireless communication module 230;
the main control module 220 is configured to obtain a power supply parameter value, and upload the power supply parameter value to the server through the wireless communication module 230, so that the server determines a regulation and control policy of the oil engines of different base stations according to the power supply parameter value of the oil engine of different base stations.
In this embodiment, the detection module may not only directly detect the power supply parameter information of the oil engine through the oil engine connection terminal 250, but also directly detect the commercial power supply parameter value through the commercial power connection terminal 260.
Illustratively, the detection module may comprise a frequency detection module, which may preferably be a FFT (fast fourier transform ) spectrum analyzer. The FFT spectrum analyzer is connected with the output end of the base station power distribution cabinet through the power distribution cabinet connecting terminal 240 and used for detecting the power supply frequency of the base station to obtain a power supply frequency value.
It should be noted that, because the maintenance-replacing personnel can switch the commercial power supply and the oil engine power supply through the switch of the base station power distribution cabinet, therefore, in order to avoid the deliberate operation of human factors to mistakenly use the commercial power supply as the oil engine to generate electricity, that is, the utility power is actually supplied to the base station, and the operator pays the maintenance company for the oil engine power generation, in order to avoid the above situation, when the operator receives the oil engine power generation notified by the operator, further power supply parameter value detection can be carried out in a mode that an operator remotely controls the monitoring terminal based on the NB-IOT cloud platform server, for example, the main control module may control the detection module to directly detect the power supply parameter information of the oil engine through the oil engine connection terminal in the embodiment, of course, the commercial power supply parameter value can be directly detected through the commercial power connecting terminal, so that whether the oil engine is in the power generation state or not is further confirmed. The setting can effectively avoid unnecessary oil engine power generation cost caused by misrepresentation of human factors, and ensure the accuracy of the oil engine power generation data.
Further, the main control module in this embodiment has a function of uploading the power supply parameter value to the server, and also has a function of determining the power supply mode according to the power supply parameter value. For example, the main control module may determine a power supply mode of the base station according to the power supply frequency value and the power supply voltage value, and upload the power supply mode to the server through the wireless communication module for reference by the server.
Specifically, the power supply mode of the base station may include a commercial power supply mode, an oil engine power generation mode, and a storage battery power supply mode. If the main control module determines that the current power supply mode is the oil engine power generation mode through the power supply frequency value, the detection module can be controlled to continue to detect the power supply parameter value of the oil engine through the oil engine connecting terminal, and whether the oil engine is in the working state is judged by obtaining the power supply parameter value, so that the accuracy of the oil engine power generation data is further improved. In addition, after the main control module uploads the judgment result to the server, the server can confirm the judgment result of the main control module on the power supply mode again according to the power supply parameter value uploaded by the main control module. The method has the advantages that false feedback of human factors to the oil engine power generation is avoided, accurate monitoring of the oil engine power generation is achieved, and therefore the oil engine power generation cost is effectively controlled.
In addition to the utility power supply mode and the oil engine power generation mode, the battery power supply mode in the present embodiment is generally a dc power supply, generally 48V. The storage battery power supply mode is generally used for supplying power to the base station when external alternating current is cut off, namely, the commercial power is cut off or the oil engine power generation mode cannot be started. And the commercial power supply mode and the oil engine power generation mode are both alternating current power supply, so that the storage battery can be charged through the alternating current-to-direct current module in the monitoring terminal before the storage battery is started to supply power.
