Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1, a flowchart illustrating steps of a monitoring method for rental equipment according to a first embodiment of the invention is shown. It is to be understood that the flow charts in the embodiments of the present method are not intended to limit the order in which the steps are performed. The following description is made by way of example with the computer device or server 2 as the executing agent. The details are as follows.
Step S100, renting equipment operation information sent by a plurality of terminal equipment is received, wherein the renting equipment operation information comprises a current value of the renting equipment and an equipment identifier corresponding to the renting equipment, one terminal equipment corresponds to one renting equipment, and the terminal equipment acquires the current value of the renting equipment in a current mutual inductance mode.
Specifically, terminal equipment is the equipment bracelet, and the equipment bracelet includes power supply battery, current transformer and communication module, and the equipment bracelet can upload lease equipment operation information to the server through NB IoT mode or 2G mode. When the equipment bracelet is installed on the leasing equipment, the bracelet identification and the equipment identification are pre-recorded in the server, and the binding relationship or the association relationship between the bracelet identification and the equipment identification is established. The current transformer is connected with the three-phase power of the leasing equipment, the conductor in the magnetic flux is changed through the electromagnetic induction principle, electromotive force can be generated, and the principle of measuring the current change in the conductor is achieved by measuring the magnetic flux around the electrified lead. The communication module and the current transformer are used for carrying out electric signal transmission through cables. The configuration information is according to the equipment bracelet of the collection operational information that every leased equipment corresponds, and every equipment bracelet all is equipped with the bracelet sign. The communication module can include an NB IoT module and a 2G module, and collects the position information of the leasing equipment based on the NB IoT or 2G base station positioning technology. And the communication module performs data interaction with the communication base stations and performs cross positioning according to the positions of the communication base stations performing interaction, so as to determine the position information of the rental equipment. The management terminal is an administrator terminal corresponding to the server (i.e., the management platform).
Referring to fig. 2, before the step S100, the method includes a step S10:
step S11, sending a current acquisition instruction to the terminal device according to configuration information, wherein the configuration information comprises a current value of the rental device and associated information of the terminal device and the device identifier acquired according to a preset period, and storing the associated information to a block chain platform.
Specifically, the preset period is customized, such as 2 minutes. The communication module and the current transformer are used for carrying out electric signal transmission through cables. The configuration information is according to the equipment bracelet of the collection operational information that every leased equipment corresponds, and every equipment bracelet all is equipped with the bracelet sign. Uploading the associated information to the blockchain can ensure the security and the fair transparency to the user. The user equipment may download the association information from the blockchain to verify whether the association information is tampered. The blockchain referred to in this example is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, and the like. A block chain (Blockchain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next block. The blockchain may include a blockchain underlying platform, a platform product service layer, an application service layer, and the like.
And step S12, receiving the current value sent by the terminal equipment based on the current acquisition instruction.
Specifically, the device bracelet may upload the electrical rental device operation information to the server in an NB IoT manner or a 2G manner.
Illustratively, after the step S100, the method includes:
and inquiring a pre-configured current upper limit threshold according to each equipment identifier, and when the current value corresponding to each rental equipment is greater than or equal to the current upper limit threshold, judging that the rental equipment has a fault and triggering alarm information.
Specifically, after receiving the current value, the server queries a preconfigured current upper limit threshold according to the device identifier, and when the current value is greater than or equal to the current upper limit threshold, it is determined that the rental device has a fault, and an alarm message is triggered.
Exemplarily, the equipment bracelet can also detect the current loop among the current transformer through the current loop detection module among the current transformer in real time, when detecting the disconnection of current loop, triggers to demolish alarm information to management terminal through the communication module. In addition, the equipment bracelet can also detect the electric quantity of power supply battery through the communication module, when detecting that the electric quantity is less than preset electric quantity threshold value, triggers the warning information that battery electric quantity is low excessively.
Exemplarily, referring to fig. 3, after the step S100, a step S110 is included:
step S111, counting the current value quantity of each rental device collected in the preset time period, and comparing the current value quantity of each rental device with the preset quantity corresponding to each rental device.
Specifically, the current value cache that the equipment bracelet will gather through communication module is in local to according to the cycle of preconfiguring with cache on server a plurality of current values and bracelet sign of local. And when the server receives the current values of the various leasing equipment, counting the received number. The total current quantity to be received in the periodic time is stored in the server in advance, and the total current quantity of each leasing device is consistent.
Step S112, if the current value quantity is smaller than the preset quantity, indicating that the rental equipment has current value missing, and triggering prompt information of the current value missing.
Specifically, by comparing the current value number with the preset number, it is known whether there is a current value missing, which can be understood as packet loss. When the current value number is smaller than the preset number, the packet loss phenomenon is indicated.
And S113, positioning the missing current value according to the prompt information and the timestamp corresponding to the current value.
Specifically, each current value corresponds to a timestamp, the server determines whether current values are missing or not according to the number of the received current values and the preset number, if so, the missing current values are located according to the timestamps corresponding to the current values, and prompt information indicating the missing current values is triggered, so that packet loss detection is realized.
Step S120, inquiring a preset current threshold interval of the rental equipment corresponding to the equipment identifier in each running state according to the equipment identifier, and determining the running state of each rental equipment according to the current threshold interval corresponding to the current value, wherein the running state comprises a working state, a standby state and a shutdown state.
In particular, each operating state is preconfigured with a respective current threshold interval. For example, when the current value is greater than 3 amperes, the rental equipment is determined to be in the working state, when the current value is less than or equal to 3 amperes, the rental equipment is determined to be in the standby state, and when the current value is 0, the rental equipment is determined to be in the shutdown state.
The preset current threshold interval is obtained by the server through statistical analysis according to a single rental device and/or a plurality of historical current values corresponding to a plurality of rental devices of the same device type. The server can use the similarity between the current values as a label to perform unsupervised learning to obtain the current threshold value intervals.
Step S140, counting a status ratio of each rental device corresponding to each operating status within a preset time period.
Specifically, a preset time period is preset, the preset time period refers to monitoring the accumulated time length of the day, and the time length of each running state in the preset time period is counted to calculate the state ratio.
Exemplarily, referring to fig. 4, the step S140 includes:
step S141, acquiring a corresponding acquisition record of each rental device in a preset time period, wherein the acquisition record comprises a plurality of acquisition times and an operation state corresponding to each acquisition time.
Specifically, an acquisition record is generated for the acquisition of the current value within a preset time period, and the running state is determined according to the corresponding current value during each acquisition.
Step S142, counting the number of acquisition times corresponding to each operation state, so as to calculate the state occupation ratio of each operation state according to the number of acquisition times corresponding to each operation state.
Specifically, if the sampling is performed n times within a preset time, and the interval time t of each sampling is consistent, when the sampling number of the operating state is m (m ═ n), the state ratio corresponding to the operating state is m/n.
For example, the acquisition frequency of the device bracelet is 15 minutes, for example, 4 times of acquisition within 60 minutes, where the first and second acquisition time nodes are in an operating state, the third acquisition time node is in a standby state, and the fourth acquisition time node is in an off state, the calculated operating state ratio is 2 × 15/60-50%, the standby state ratio is 15/60-25%, and the off state ratio is 15/60-25%.
Exemplarily, referring to fig. 5, after the step S140, a step S150 is included:
and step S151, when the state occupation ratio corresponding to the working state of the rental equipment is smaller than the corresponding operation rate threshold value, inquiring the operation rate of the rental equipment in the last preset days.
Specifically, the operation rate threshold is calculated based on the historical monitoring time corresponding to the device identifier, the historical time corresponding to each operating state, and the currently calculated state time, and the operation rate threshold is the working state ratio. When the server detects a preset trigger condition, inquiring the total monitoring time length corresponding to the equipment identifier and the running time length corresponding to each running state, calculating the state ratio of each running state according to each running time length and the historical monitoring time length, and comparing the calculated state ratio with the corresponding preconfigured state ratio threshold. The preset trigger condition, such as the current system time, is 24 points.
Step S152, if the operation rate of the latest preset days is smaller than the operation rate threshold value, the user corresponding to the rental equipment is judged to be a high-risk user.
Specifically, when the work rate is calculated in the last preset number of days, that is, the duty ratio of the working state is smaller than the work rate threshold, it is determined that the user corresponding to the rental device is a high-risk user.
Step S153, if the work rate of the continuous preset days is larger than or equal to the work rate threshold value, determining that the user corresponding to the rental equipment is a high-risk user.
Specifically, when the operation rate of the rental equipment for the continuous preset number of days is greater than the operation rate threshold value, it is indicated that false operation exists, or it is indicated that the risk of rental equipment transfer exists, and the user corresponding to the rental equipment is determined to be a high-risk user.
For example, when a tenant rents a plurality of leased devices, the server calculates the operating rate for each leased device, and obtains the current operating rate by performing weighted average on the operating rates.
Exemplarily, the equipment bracelet communication module collects the position information of the rental equipment, and uploads the collected current value, the collected position information and the bracelet identification of the equipment bracelet communication module to the server. The server inquires pre-stored target position information according to the equipment identifier bound by the bracelet identifier, calculates the position offset of the leasing equipment according to the position information and the target position information, and feeds back transferred risk prompt information of the equipment to the management terminal when the position offset is greater than the preset offset.
It can be understood that, when the position offset amount is greater than the preset offset amount, the server may further continue to calculate the state ratio in the above manner, and when the position offset amount and/or the state ratio meet the preset risk determination condition, feed back the risk prompt information to the management terminal.
And step S160, pushing the state ratio to the user terminal for displaying.
Specifically, the server may push the state duration and the corresponding state duty ratio corresponding to each operation state to the user terminal for comparison and display. And the server receives the current value and the timestamp reported by the equipment bracelet, dynamically updates the time interval corresponding to the equipment identifier and the running state according to the timestamp and the currently determined running state, and pushes the time interval corresponding to each running state to the user terminal for displaying.
Exemplarily, referring to fig. 6, the step S160 includes:
step S161, receiving a trigger condition of the user, where the trigger condition includes a terminal display condition.
Specifically, when the user needs to analyze and display the rental device, the trigger condition is sent to the server to perform corresponding operation.
And S162, performing statistical analysis on the current value of the rental equipment according to the trigger condition and the position area and/or the equipment type corresponding to the rental equipment to generate an industry report, and pushing the generated industry report to a specified terminal for displaying.
Specifically, when the server detects a specified trigger condition, the server performs statistical analysis on the current value of the rental equipment according to the location area (such as province, city, area and the like) and/or the equipment type to generate an industry report, and pushes the generated industry report to a specified terminal for display. Wherein, the appointed terminal is corresponding to a government department, a statistical bureau or an appointed financial institution.
For example, the server calculates, according to the device type deployed in each province, the leased devices corresponding to each device type and the current values corresponding to each leased device, the running state distribution of each leased device and/or each device type in each province. Therefore, the start-up situation of various rental equipment in each area can be known, so that equipment deployment and strategy making can be conveniently carried out according to the start-up situation.
