Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced in other ways than those described herein, and it will be apparent to those of ordinary skill in the art that the present application is not limited to the specific embodiments disclosed below.

Next, the present application will be described in detail with reference to the drawings, and in the detailed description of the embodiments of the present application, the cross-sectional views illustrating the structure of the device are not enlarged partially according to the general scale for convenience of illustration, and the drawings are only examples, which should not limit the scope of the protection of the present application. In addition, the three-dimensional dimensions of length, width and depth should be included in the actual fabrication.

As described in the background section, it has become a research focus of those skilled in the art to provide an intelligent identification that can help to achieve a comprehensive supervision of asset devices.

The known asset device monitoring is usually implemented by an Identification device installed on the asset device, and the Identification device is usually implemented by an electronic tag or a sensing terminal, where the electronic tag mainly implements monitoring on the asset device by using a Radio Frequency Identification (RFID) technology, and the sensing terminal is a terminal with a built-in sensing unit and a communication unit, acquires sensing information of the asset device by the sensing unit, and uploads the sensing information to a server by the communication unit, thereby implementing monitoring on the asset device.

However, the existing identification devices have single functions, either only have RFID functions or only have sensing functions, and the existing electronic tags or sensing terminals have single functions, which brings inconvenience to the life cycle management of asset devices and the state management of asset devices, and the like, and cannot comprehensively supervise the asset devices, thereby affecting the supervision of the asset devices.

The endurance of the identification device is also crucial. In order to guarantee the cruising ability of the existing positioning tag, a double-battery design is generally adopted, one battery is used as a common power supply, and the other battery is used as a standby power supply. However, in particular operation, when switching between two batteries, there are two critical issues: 1. the problem of power-off time during battery switching; 2. short circuit between batteries when the batteries are switched. The specific reason is as follows: the existing identification equipment adopts discrete elements to build a battery switching circuit, uses an MOS tube as a battery switching circuit switch, compares the voltage of a common battery with the preset voltage by using a comparator, and realizes battery switching through the battery switching circuit according to the comparison result. Because the delay of the comparator is larger, when the battery is switched, if the switching speed is lower, the power-off time is longer when the battery is switched; if the switching speed is high, the two batteries are short-circuited, so that the normal work of the identification equipment is influenced, and the monitoring of the motion state of the asset equipment is further influenced.

And when the MOS tube is used as a switch, the battery switching circuit has larger leakage current and larger power consumption due to the existence of the body diode of the MOS tube, so that the power consumption of the identification equipment is larger, the low-power-consumption application cannot be realized, and the actual application of the identification equipment is influenced.

In addition, the existing identification equipment adopts discrete elements to build a battery switching circuit, so that the circuit structure is complex, the occupied area is large, the power consumption is high, the debugging is difficult, and the practical application of the intelligent identification of the multi-dimensional Internet of things is influenced.

Based on this, the embodiment of the present application provides a multidimensional internet of things intelligent identifier, which is used for monitoring asset devices, and as shown in fig. 1, the intelligent identifier includes: the system comprises a radio frequency identification electronic tag 10, an identity code (not shown in the figure), and a main control chip 20, an internet of things positioning module 30, an attitude sensing module 40, an electric leakage monitoring module 50 and a first temperature sensing module 60 which are positioned on a circuit board 11;

the internet of things positioning module 30 is connected with the main control chip 20, and the main control chip 20 controls the internet of things positioning module 30 to obtain positioning information of the asset equipment and upload the positioning information to a server;

the attitude sensing module 40 is connected with the main control chip 20, the main control chip 20 controls the attitude sensing module 40 to acquire attitude information of the asset equipment and upload the attitude information to a server, and the attitude information comprises an inclination angle and an acceleration of the asset equipment; it should be noted that the tilt angle of the asset device is a tilt angle of the asset device relative to a ground coordinate;

the leakage monitoring module 50 is connected to the main control chip 20, and the main control chip 20 controls the leakage monitoring module 50 to obtain the leakage voltage of the asset device and upload the leakage voltage to a server;

It should be noted that, as shown in fig. 1, in order to reduce the space occupied by the intelligent identifier of the multidimensional internet of things, the circuit board 11 includes an upper circuit board 111 and a lower circuit board 112, but this is not limited in this embodiment of the application, as the case may be. Wherein, upper circuit board 111 with lower floor's circuit board 112 is through row needle welded fastening, main control chip 20 gesture sensing module 40 with first temperature sensing module 60 is located on lower floor's circuit board 112, thing networking positioning module 30 with electric leakage monitoring module 50 is located on the upper circuit board 111. The circuit board may be made of acrylonitrile-butadiene-styrene plastic, polycarbonate plastic, polyamide plastic, polypropylene plastic, and the like, which is not limited in the embodiment of the present application and is determined as the case may be. It should be further explained that the internet of things positioning module, the main control chip, the posture sensing module, the electric leakage monitoring module and the first temperature sensing module are located on the circuit board, the main control chip and the connection between the internet of things positioning module is realized by the circuit board wiring, the main control chip and the connection between the posture sensing modules are realized by the circuit board wiring, the main control chip and the connection between the electric leakage monitoring module is realized by the circuit board wiring, the main control chip and the connection between the first temperature sensing module are realized by the circuit board wiring, which is not shown in fig. 1.

Specifically, in this embodiment of the present application, the intelligent identifier includes a radio frequency identification electronic tag (RFID electronic tag) and an identity code (two-dimensional code), and stores the asset device identity information, that is, each asset device has a unique RFID electronic tag and an identity code corresponding thereto, so as to identify the asset device, which can help to realize fast inventory of the asset device, and avoid the situation that the asset device is replaced and the account is inconsistent. Because each asset device is provided with the RFID electronic tag and the identity code which are uniquely corresponding to the asset device, when the asset device is strongly operated and detected, the field operating personnel can acquire the identity information of the asset device through the RFID electronic tag and the identity code, and the field operating personnel can conveniently perform corresponding processing on the asset device. And the identity information of the asset equipment stored by the RFID electronic tag and the identity code generally comprises a manufacturer, a place of manufacture, a date of departure and the like, so that the management of the life cycle of the asset equipment can be realized through the RFID electronic tag and the identity code. Meanwhile, the intelligent identification comprises the RFID electronic tag and the identity code, so that the intelligent identification has active and passive identification at the same time, and a user can select a proper identification method according to the requirement, thereby being beneficial to the practical application of the intelligent identification.

The intelligent identification further comprises an internet of things positioning module, an attitude sensing module, an electric leakage monitoring module and a first temperature sensing module, wherein the internet of things positioning module can acquire positioning information of the asset equipment and upload the positioning information to a server so as to position the asset equipment and avoid the loss of the asset equipment; the attitude sensing module can acquire attitude information of the asset equipment, upload the attitude information to a server, monitor whether the asset equipment is abnormal or not and monitor the motion state of the asset equipment; the leakage monitoring module acquires the leakage voltage of the asset equipment and uploads the leakage voltage to the server to monitor whether the asset equipment leaks electricity or not and further monitor whether the asset equipment is in a safe operation state or not, so that the intelligent identification has the functions of asset equipment positioning, transaction monitoring and safety monitoring while identity recognition can be realized, multiple functional modules are integrated, the asset equipment can be monitored from multiple dimensions, comprehensive supervision on the asset equipment is facilitated, and the leakage monitoring module can be widely applied to multiple fields of asset equipment management, such as field operation management, life cycle management, logistics management and the like of the asset equipment.

In addition, the intelligent identifier integrates multiple functional modules, so that the intelligent identifier has the capability of configuring the functions, but the embodiment of the application does not emphasize that the intelligent identifier has to have all the functions, because the more functions, the higher price is possible, so that in actual application, the functions can be selectively configured according to the actual requirements of customers, so as to meet the requirements of the customers on functions, cost and the like.

The intelligent identification further comprises a first temperature sensing module used for acquiring a first temperature signal of the environment where the asset equipment is located at fixed time, so that the main control chip can adjust the frequency of acquiring the first temperature signal and the frequency of acquiring the attitude information of the asset equipment according to the first temperature signal, the intelligent identification can adjust the working state of the intelligent identification according to the actual condition of the asset equipment, the power consumption waste is avoided, and the purpose of reducing the energy consumption is achieved. Specifically, when a first temperature signal acquired by the first temperature sensing module and a previously acquired first temperature signal have a severe change, which indicates that the temperature of the environment where the asset device is located has a large change, in order to ensure the safety of the asset device, it is necessary to increase the frequency of acquiring the first temperature signal and the frequency of acquiring the attitude information of the asset device, and monitor the temperature change of the environment where the asset device is located and the motion state of the asset device in real time, so as to take corresponding measures to ensure the safety of the asset device; when the first temperature signal acquired by the first temperature sensing module does not change much with the previously acquired first temperature signal, and is a series of approximately static values, it is indicated that the temperature of the environment where the asset device is located is stable, and the temperature of the external environment does not change drastically to affect the safety of the asset device, and at this time, the first temperature signal and the attitude information of the asset device do not need to be acquired frequently, and only the first temperature signal and the attitude information of the asset device need to be acquired at a low frequency, so that the intelligent identifier can adjust the working state according to the actual situation, and avoid power consumption waste. It should be noted that, when the intelligent identifier starts to work, a fundamental frequency for acquiring the first temperature signal and the attitude information of the asset device is set according to the geographical location of the asset device, and then adjustment is performed according to the actually acquired first temperature signal. And when the environment temperature of the asset equipment is higher or lower, the fundamental frequency of the acquired first temperature signal and the attitude information of the asset equipment is greater than the fundamental frequency when the environment temperature of the asset equipment is moderate.

It should be further noted that the operating state of the leakage monitoring module is also affected by the ambient temperature of the asset device, so that the leakage voltage obtained by the leakage monitoring module is inaccurate. In the embodiment of the present application, the main chip may further compensate the leakage voltage obtained by the leakage monitoring module according to the first temperature signal obtained by the first temperature sensing module, so as to ensure reliability of the leakage voltage, accurately monitor the leakage voltage of the asset device, help to ensure safety of the asset device, avoid influence on normal operation of the asset device due to leakage of the asset device, and avoid safety accidents caused by leakage of the asset device when the voltage of the asset device is high.

Meanwhile, the intelligent identification is not limited to the material of the shell, and the shell of the intelligent identification can be made into a shell supporting magnetic attraction, a binding belt, a rivet and other installation modes, so that the intelligent identification is convenient to install. In addition, although the intelligent mark is provided with a plurality of functional modules, the plurality of functional modules are integrated in a large environment that the volumes of various types of devices are gradually reduced, the volume of the intelligent mark is not increased, the volume of the intelligent mark is small, and the size of the intelligent mark can reach 200mm 39mm 24mm, so that the intelligent mark is convenient to use in practice.

On the basis of the above embodiments, in an embodiment of the present application, as shown in fig. 2, the internet of things positioning module 30 includes a narrow-band internet of things communication unit 31 and a dual-mode positioning unit 32, the dual-mode positioning unit 31 includes a beidou positioning antenna and a GPS positioning antenna, wherein the beidou positioning antenna is used for receiving beidou satellite positioning signals, the GPS positioning antenna is used for receiving GPS satellite positioning signals, so that fast positioning can be achieved by using the dual-mode positioning unit, and positioning accuracy is high, the main control chip 20 is respectively connected to the narrow-band internet of things communication unit 31 and the dual-mode positioning unit 32, and is used for controlling the dual-mode positioning unit 31 to obtain positioning information of the asset device, transmitting the asset setting positioning information to the internet of things communication unit 32, and controlling the narrow-band internet of things communication unit 32 to upload the positioning information of the asset device to a server, the method and the device can acquire the positioning information of the asset equipment in real time and accurately master the real-time dynamic state of the asset equipment so as to realize the visual supervision of the asset equipment. It should be noted that the main control chip is connected to the narrowband internet of things communication unit and the dual-mode positioning unit through circuit board routing, and a connection line connecting the main control chip to the narrowband internet of things communication unit and the dual-mode positioning unit is not shown in fig. 2.

When the attitude sensor monitors the attitude information of the asset equipment, the attitude sensor can discontinuously acquire the attitude information within a period of time and upload the acquired attitude information to the server, so that the motion state of the asset equipment is monitored, and the asset equipment is monitored conveniently. It should be noted that the intelligent identifiers are all in a sleep state in normal conditions, and positioning information, attitude information, leakage voltage and the like of the asset equipment are acquired at regular time through self program setting. However, in order to ensure supervision of the asset device, the intelligent identifier may also be awakened in an abnormal working state, for example, when the attitude sensor monitors that the attitude information of the asset device is abnormal, the intelligent identifier may be awakened from a sleep state, and at this time, the intelligent identifier may control the attitude sensing module to acquire the attitude information of the asset device through the main control signal, and may also control the internet of things positioning module to acquire the asset device positioning information through the main control chip, and control the leakage monitoring module to acquire the leakage voltage of the asset device, and upload the leakage voltage to the server.

And the intelligent identification obtains the attitude information of the asset equipment through the attitude sensor, namely obtains the attitude information of the intelligent identification, and can also be used for realizing transaction anti-theft alarm of the multidimensional Internet of things intelligent identification and preventing the multidimensional Internet of things intelligent identification from being stolen.

However, the present application is not limited to this, and in other embodiments of the present application, other device transaction triggering manners may be further provided to implement device transaction anti-theft alarm, which is specifically determined according to the situation. It should be noted that, in an embodiment of the present application, the attitude sensor includes a six-axis gyroscope, and the attitude information of the asset device is acquired by the six-axis gyroscope, but the present application does not limit this to this, and the attitude sensor is determined as the case may be.

In order to more clearly understand the multidimensional internet of things intelligent marker provided by the embodiment of the application, the working process of the intelligent marker will be described in detail below.

Specifically, as shown in fig. 9, fig. 9 is a working flow chart of the multidimensional internet of things intelligent identifier, first, the intelligent identifier starts to work through power-on or wake-up, and four wake-up modes are timing wake-up (also called RTC wake-up), anti-theft key press or lift-up wake-up, attitude sensing wake-up and leakage monitoring wake-up, which are respectively set by the intelligent identifier, where the attitude sensing wake-up means that the attitude sensing module detects that the acceleration change of the asset device exceeds a threshold value, which causes the level change of an output pin of the attitude sensing module, so as to wake up the intelligent identifier, and the leakage monitoring wake-up means that the leakage monitoring module monitors that the asset device has leakage, so as to wake up the intelligent identifier; the intelligent identification is awakened and then initialized, and an awakening mode is detected, namely, the intelligent identification is awakened in which mode, the next operation is carried out according to the difference of the awakening modes, if the intelligent identification is awakened by self-set timing awakening, the intelligent identification can acquire the current positioning information, temperature information, attitude information, electric leakage information and other data, upload the data to the server, then enter a dormant state, wait for the next timed awakening, acquire the current positioning information, temperature information, attitude information, electric leakage information and other data again, and upload the data to the server; if the intelligent identification is awakened through attitude sensing or electric leakage monitoring, the identification can acquire data such as current positioning information, temperature information, attitude information, electric leakage information and the like, upload the data to the server, repeat the operation for five times, enter a dormant state, wait for next attitude sensing awakening, electric leakage monitoring awakening or timing awakening, acquire data such as current positioning information, temperature information, attitude information, electric leakage information and the like again, and upload the data to the server; if the intelligent identification is awakened through the anti-theft key, the intelligent identification acquires positioning information, temperature information, posture information and the like, uploads the positioning information, the temperature information, the posture information and the like to the server, repeats five times, enters a dormant state, returns to a timing awakening working mode, waits for the next timing awakening, acquires data of the current positioning information, temperature information, posture information and the like again, and uploads the data to the server; after the intelligent identification uploads the collected data to the server, the server waits for issuing an instruction and data according to the uploaded data, if the server returns an OK instruction and does not issue data, the situation that the motion state of asset equipment is not abnormal is shown, the multidimensional Internet of things intelligent identification continues to work according to the current working mode, the multidimensional Internet of things intelligent identification is not modified in parameters, and directly enters a dormant state to wait for awakening next time; if the server issues instructions and data, the multidimensional Internet of things intelligent identification judges whether the server issues the instructions to be in compliance, namely whether the issued instructions meet the safety regulations of the multidimensional Internet of things intelligent identification is judged, if the issued instructions are in compliance, parameters are set according to the instructions and the issued data, if the issued instructions are not in compliance, the previous parameters are continuously used, the parameters are not modified, and then the server enters a dormant state to wait for next awakening.

It should be noted that reducing the power consumption of the identification device is also a key step in the development of the identification device. In the embodiment of the application, in order to reduce the power consumption of the intelligent identification of the multidimensional internet of things and optimize the working process, the intelligent identification mainly achieves the purpose through two aspects of static power consumption and dynamic power consumption.

In the aspect of static power consumption, power consumption reduction and workflow optimization are mainly realized by setting two modes of power gating and logic units with different thresholds. For the logics with different thresholds, the low-threshold logic unit has the characteristics of high speed and large leakage current, and the high-threshold logic unit has the characteristics of low speed and small leakage current, so that in order to reduce power consumption and optimize a working process, the low-threshold logic unit is used on a critical path of the intelligent identifier to optimize the working process and improve working efficiency, and the high-threshold logic unit is used on a non-critical path of the intelligent identifier to reduce leakage current and further reduce power consumption, so that the power consumption of the intelligent identifier can be reduced and the working process can be optimized. The identifiable critical path is a path related to asset equipment supervision and assurance of intelligent identification reliability, such as collection positioning information, temperature information, attitude information and leakage information, and other paths are non-critical paths, but the method is not limited to the above, and is specifically determined according to the situation.

For reducing the power consumption of the intelligent identification and optimizing the working process by adopting power gating, the principle is that the power gating controls the on and off of one or some working modules of the intelligent identification, so that the working modules work when acquiring data and are turned off at other times, and the power consumption of the intelligent identification is reduced and the working process is optimized. Specifically, taking the internet of things positioning module NB of the intelligent identifier as an example, as shown IN fig. 10, fig. 10 is a circuit diagram of a power gate of the internet of things positioning module, where SNB is a switching signal input terminal, NB3.3V-IN is a power input terminal, NB3.3V is a power output terminal, and is connected to the internet of things positioning module NB, R21 and R23 are resistors with fixed resistance values, Q4 is a triode, Q5 is a P-type field effect transistor, when a switching signal input by the switching signal input terminal SNB is a low level, the triode Q4 is turned off, a gate voltage of the P-type field effect transistor Q5 is pulled high by the resistor R23, so that the P-type field effect transistor Q5 is turned off, and the internet of things positioning module NB is not provided with a voltage signal input, so that the internet of things positioning module NB is turned off; when the switching signal of switching signal input end SNB input is the high level, triode Q4 switches on, and P type field effect transistor Q5 grid voltage is drawn low by resistance R23 for P type field effect transistor Q5 switches on, and thing networking orientation module NB has voltage signal input, makes thing networking orientation module NB open, and then can control opening and closing of thing networking orientation module NB.

In the aspect of dynamic power consumption, the power consumption is reduced and the work flow is optimized mainly by two modes of gating a clock and adjusting dynamic voltage. For realizing the reduction of power consumption and the optimization of the work flow by the gated clock, the principle is to close the function and the clock which can not be used temporarily by the intelligent identification by the gated clock, and further realize the reduction of the power consumption and the optimization of the work flow. And when the intelligent identification works, a large part of power consumption is generated by the turnover of the clock network, and the gated clock has a strong inhibiting effect on the turnover power consumption of the clock network, so that the power consumption can be reduced by the gated clock. Meanwhile, when the whole intelligent identification system is in a non-working state, all functions and clocks can be turned off through a gate control clock, so that the whole intelligent identification system is in a non-activated state, and the power consumption of the intelligent identification is reduced to a certain extent.

For realizing the reduction of power consumption and the optimization of a working process by dynamic voltage regulation, the principle is that the working voltage and the working frequency of different working modules are regulated to be reduced as much as possible to just meet the minimum requirements of the respective working modules by the dynamic voltage regulation to realize the reduction of the power consumption and the optimization of the working process, for example, when the intelligent identification carries out data transmission, the intelligent identification works under a high-voltage condition, and when the intelligent identification is in a dormant state, the intelligent identification works under a low-voltage condition to reduce the power consumption. In a specific application, the method is mainly used for temperature acquisition and acceleration acquisition, if the intelligent identification acquires data after a period of time, the acquired temperature data and acceleration data are approximate static values and do not exceed the standard, the acquired acceleration data are approximate static values and do not exceed the standard, the intelligent identification is in a stable state, namely the asset equipment is in a stable motion state, at the moment, the data acquisition frequency can be reduced through dynamic voltage regulation, for example, the data acquisition frequency is reduced from 100Hz to 1Hz, so that the power consumption can be saved, the acquisition of the temperature and the acceleration is not influenced, and the normal work of the intelligent identification is ensured. In addition, because the external environment temperature is too high or too low when the intelligent identification works, the work of the intelligent identification is influenced, when the intelligent identification collects temperature data, the initial data collection frequency is set according to the position of the intelligent identification on a map, the data collection frequency of a region with higher temperature or lower temperature is higher, after a period of data collection, if the collected temperature data change is more stable and does not exceed the standard, the data collection frequency can be reduced, for example, when the temperature data collected by the intelligent identification for one to two days are all exceeded, the data collection frequency can be reduced from one minute to ten minutes or more, and if the collected data change is larger and exceeds the allowable range, the data collection frequency is increased.
