The terminology used herein is for the purpose of describing embodiments of the utility model only and is not intended to be limiting of the utility model.

Referring to fig. 1, fig. 1 is a block diagram of an intelligent detection device according to an embodiment of the present utility model. As shown in fig. 1, the smart detection device includes: a power module 110, a first detection module 120, a second detection module 130, and a main control module 140. The power module 110 is connected to the first detection module 120 and the main control module 140, and the first detection module 120 and the second detection module 130 are connected to the main control module 140.

In the embodiment of the utility model, the intelligent detection device is applied to the cargo transportation box body, wherein the cargo transportation box body is of a sealing structure, and the intelligent detection device shown in the figure 1 is arranged on the cargo transportation box body. The first detection module 120 is isolated from the external environment and is in a closed state by installation, so that when the intelligent detection device is removed from the cargo transportation box, the closed space of the first detection module 120 is destroyed, and light is irradiated. Meanwhile, the second detection module 130 is isolated from the external environment but is communicated with the inside of the cargo transportation box body by installation, so that the second detection module 130 can detect the illumination condition of the inside of the cargo transportation box body. The utility model can detect that the intelligent detection equipment is disassembled, alarm in time when the intelligent detection equipment is disassembled, monitor the internal illumination environment of the cargo transportation box body and strengthen the safety management and protection of the cargo in the transportation process.

Specifically, the power module 110 is configured to supply power to the first detection module 120 and the main control module 140;

the first detection module 120 is configured to output a first signal to the main control module 140 when illumination is detected, where the illumination light source includes a solar light source or an electric light source.

The second detection module 130 is configured to start performing detection according to the control signal sent by the main control module 140, so as to continuously output a voltage signal to the main control module 140.

Referring to fig. 2, fig. 2 is a flowchart of steps performed by the main control module according to an embodiment of the present utility model, including but not limited to steps S201 to S203.

Step S201, when a first signal is detected, first position information of the intelligent detection equipment is collected, and alarm information and the first position information are sent to a data center platform.

Step S202, or, ADC sampling is carried out on the voltage signal to obtain the illuminance inside the cargo transportation box body, and the illuminance is sent to the data center platform.

Step S203, or when receiving the location information request sent by the data center platform, the second location information where the intelligent detection device is currently located is collected, and the second location information is sent to the data center platform.

In the embodiment of the present utility model, since the main control module 140 is connected to the first detection module 120, when receiving the first signal sent by the first detection module 120, the first location information where the intelligent detection device is currently located can be collected, and meanwhile, corresponding alarm information is generated. The alert information and the first location information may then be sent to a data center platform. Therefore, the time and the geographic position of the disassembled intelligent detection equipment can be obtained, and the alarm tracing function of the disassembled intelligent detection equipment is realized.

In the embodiment of the utility model, since the main control module 140 is connected with the second detection module 130, the voltage signal output by the second detection module 130 during working can be subjected to ADC sampling, so that the illuminance inside the cargo transportation box can be obtained and sent to the data center platform. Can monitor the illumination in the cargo transportation box body to strengthen the safety control and the protection to the goods in the transportation.

It should be noted that, the main control module 140 may further monitor whether the cargo transportation box is opened by performing ADC sampling on the voltage signal output by the second detection module 130 during operation, and the obtained illuminance in the cargo transportation box.

It can be appreciated that when the cargo itself in the cargo transportation box needs illumination for the fresh-keeping of the cargo, at this time, the light source is provided in the cargo transportation box, and the illuminance in the cargo transportation box can be detected by the second detection module 130, so that whether the cargo transportation box is opened or not can be detected according to the change of the illuminance. Meanwhile, whether the goods are normally preserved or not can be determined according to the change of illuminance, and the goods can be timely known and processed when the preservation lamp source is damaged, so that the goods are prevented from going bad and rotting.

In the embodiment of the utility model, the main control module 140 can be in communication connection with the data center platform, so that data interaction between the main control module 140 and the data center platform can be realized. The main control module can collect second position information of the intelligent detection equipment when receiving a position information request sent by the data center platform, and send the second position information to the data center platform. Therefore, the real-time tracking of the cargo transportation box body or the cargo flow track can be realized.

It is understood that the main control module 140 may also collect location information in real time and send the collected location information to the data platform center. The position information can be acquired according to the preset interval time length, and the acquired position information is sent to the data platform center. The preset interval duration may be written into the main control module 140 through a program in advance, or the data center platform may send an instruction for acquiring the position information of the interval duration to the main control module 140.

In the embodiment of the utility model, the data center platform can be a goods supervision platform or a logistics information monitoring platform. After receiving the information (including time information, location information, alarm information, etc.) sent by the main control module, the data center platform can record and store the information, and can also send the information to a third party platform, such as each logistics site, or other goods related parties, such as merchants, buyers, etc.

In one embodiment of the utility model, the main control module comprises a location information acquisition unit and a communication unit. The position information acquisition unit is used for acquiring the current position information of the intelligent detection equipment in real time. The communication unit is used for establishing communication connection with the data center platform so as to perform data interaction with the data center platform.

The main control module is provided with the position information acquisition unit and the communication unit, and the position information of the intelligent detection equipment can be acquired in real time through the position information acquisition unit, so that the real-time tracking of the flow track of the cargo transportation box body can be realized. The communication unit is connected with the data center platform in a communication way, so that data interaction with the data center platform can be realized, the detected alarm information, position information, time information and the like are sent to the data center platform, and the data center platform performs unified supervision and storage.

In one embodiment of the utility model, the main control module is further configured to:

and sending a control signal to the second detection module according to the preset interval duration so as to control the second detection module to execute detection once per interval duration.

In the embodiment of the utility model, the control program for the main control module to send the control signal to the second detection module can be written in the main control module in advance, so that the main control module can control the output of the control signal according to the control program. Considering that the cargo transportation box body is in a dark condition under most conditions in the transportation process, the illumination environment in the cargo transportation box body can not be monitored in real time in order to save the electric energy consumption. The embodiment of the utility model presets the interval duration, so that the main control module can send a control signal to the second detection module according to the preset interval duration to control the second detection module to execute detection once per interval duration. Through detecting at intervals, the illumination intensity inside the cargo transportation box body can be effectively monitored, and meanwhile, the energy consumption of the intelligent detection equipment can be saved.

For example, the main control module may be configured to send a control signal to the second detection module every 4 hours to control the second detection module to perform detection every 4 hours, so that the data center platform may acquire data of the illuminance inside the cargo transportation box every 4 hours. The main control module can also be arranged to send a control signal to the second detection module every 30 minutes to control the second detection module to perform detection every 30 minutes, so that the data center platform can acquire the data of the illuminance inside the cargo transportation box every 30 minutes.

It should be noted that, the setting of the interval duration may be set according to the actual situation and the requirement. For example, in the case that no fresh-keeping lamp is provided in the cargo transportation box, this indicates that the cargo does not need to be kept fresh, and at this time, the supervision meaning of the illuminance in the cargo transportation box to the cargo is not very great, so that the interval duration can be set longer. And when the condition that is provided with the fresh-keeping lamp in the cargo transportation box body, indicate that the cargo needs to be fresh-keeping, at this moment, the illuminance in the cargo transportation box body is very important to the supervision of cargo, therefore, can set up that the interval duration is shorter.

It can be understood that when the fresh-keeping lamp is not arranged in the cargo transportation box body, namely, the cargo does not need to be kept fresh, and the cargo transportation box body is in a dark environment in a normal state, the second detection module can be controlled to not work through the main control module. I.e. no control signal is sent to the second detection module, so that the second detection module does not work.

In one embodiment of the utility model, the main control module is further configured to:

and when an illuminance detection request sent by the data center platform is received, a control signal is sent to the second detection module so as to control the second detection module to start to execute detection.

The embodiment of the utility model can control the work of the second detection module by sending the illuminance detection request to the main control module by the data center platform. Similarly, the data center platform may send an illuminance detection request to the main control module after preset fixed time intervals, so as to control the second detection module to perform detection once at fixed time intervals. The illumination intensity inside the cargo transportation box body can be effectively monitored, and meanwhile, energy consumption is saved.

In an embodiment of the present utility model, referring to fig. 3, fig. 3 is a flowchart illustrating steps of ADC sampling a voltage signal by a main control module provided by the embodiment of the present utility model to obtain illuminance inside a cargo transportation box, including but not limited to steps S301 to S302.

Step S301, corresponding photocurrent is calculated according to the voltage obtained by ADC sampling.

Step S302, corresponding illuminance is determined according to the corresponding relation between the photocurrent and the illuminance.

According to the embodiment of the utility model, the main control module performs ADC (analog-to-digital converter) sampling on the voltage signal output by the second detection module, so that a corresponding voltage value can be obtained. Then, according to the current calculation, the formula is as follows: photocurrent i (uA) =vout (mV)/Rss (kΩ) can be calculated to obtain a corresponding photocurrent, and then the corresponding illuminance can be determined according to the correspondence between the photocurrent and the illuminance. Thus, the master control module may send the illuminance to the data center platform after calculating the illuminance.

Referring to fig. 4, fig. 4 is an exemplary graph of photocurrent versus illuminance according to an embodiment of the present utility model. Referring to fig. 4, when a photoelectric value is calculated from a voltage value, illuminance corresponding to the photoelectric value can be obtained.

It should be noted that, in the embodiment of the present utility model, the relational expression of the illuminance and the photocurrent may be determined in advance through experiments, so that after the current value is calculated according to the voltage value, the illuminance may be directly calculated according to the relational expression of the illuminance and the photocurrent.

In one embodiment of the present utility model, referring to fig. 5, fig. 5 is a circuit diagram of a main control module provided in an embodiment of the present utility model. Referring to fig. 5, the main control module includes a main control chip U2A and a main antenna terminal RF1. A first pin (i.e., pin 46) of the main control chip U2A is connected to a first pin (i.e., pin 2) of the main antenna terminal RF1, and both a second pin (i.e., pin 1) and a third pin (i.e., pin 3) of the main antenna terminal are grounded GND. The pin 36 of the main control chip U2A is connected to the power supply voltage VBAT output by the power supply module.

The main control chip U2A of the embodiment of the utility model adopts the EC600U module, and the EC600U module has a position acquisition function and a communication function, can acquire longitude and latitude information of the current position of the cargo transportation box body, and then sends the longitude and latitude information to the data center platform so as to position the position of the intelligent detection equipment. And meanwhile, the generated alarm information, the calculated illuminance information and the like can be sent to a data center platform.

In one embodiment of the present utility model, referring to fig. 6, fig. 6 is a circuit diagram of a first detection module according to an embodiment of the present utility model. Referring to fig. 6, the first detection module includes: the first transistor Q1, the second transistor Q2, the first photoresistor R2, the first resistor R3, the second resistor R8 and the third resistor R9. The first end of the first photoresistor R2 is used for being connected with a power supply voltage VBAT output by the power supply module, and the second end of the first photoresistor R2 is connected with the first end of the first resistor R3, the first end of the second resistor R8 and the first end of the third resistor R9. The second end of the first resistor R3 is grounded GND. The second end of the second resistor R8 is connected to the base of the first transistor Q1. The collector of the first triode Q1 is connected with the second pin (i.e. pin 53) of the main control chip U2A, and the emitter of the first triode Q1 is grounded GND. The second end of the third resistor R9 is connected to the base of the second transistor Q2. The collector of the second triode Q2 is connected to the third pin (i.e., pin 74) of the main control chip U2A, and the emitter of the second triode Q2 is grounded GND.

Illustratively, when the intelligent detection device is mounted on the cargo transportation box, the intelligent detection device needs to be sealed with an external contact surface through a cover plate so as to protect the intelligent detection device from water and the like. Thereby the first detection module is in a closed state.

The working principle of the first detection module in the embodiment of the utility model is as follows:

in the dark state under the airtight condition, the resistance value of the first photoresistor R2 becomes large, so the voltage of the base electrode of the second triode Q2 is low level, and the second triode Q2 is not conducted. When the outer cover plate of the intelligent detection device is detached, namely, someone needs to detach the intelligent detection device on the cargo transportation box body, light rays can irradiate on the first photoresistor R2. At this time, the resistance of the first photoresistor R2 becomes smaller, so that the voltage of the base electrode of the second triode Q2 becomes larger, the collector electrode and the emitter electrode of the second triode Q2 are conducted, and the level of the collector electrode of the second triode Q2 is pulled down. Since the collector of the second transistor Q2 is connected to the third pin (i.e., pin 74) of the main control chip U2A of the main control module, the main control module can detect the low level signal output from the first detection module. Therefore, when the low-level signal is detected, corresponding alarm information can be generated, meanwhile, the first position information of the intelligent detection equipment is collected, and then the alarm information and the first position information are sent to the data center platform. The alarm information may include corresponding alarm time information. Therefore, the first detection module can timely alarm when detecting that the intelligent detection equipment is disassembled, and the alarm tracing function when the intelligent detection equipment is disassembled is realized.

In one embodiment of the present utility model, referring to fig. 7, fig. 7 is a circuit diagram of a second detection module according to an embodiment of the present utility model. Referring to fig. 7, the second detection module includes a second photo resistor R12 and a fourth resistor R11. The first end of the second photoresistor R12 is connected with the fourth pin (i.e. pin 14) of the main control chip U2A, and the second end of the second photoresistor R12 is connected with the first end of the fourth resistor R11. The second terminal of the fourth resistor R11 is grounded GND.

The connection part Lux1 between the second end of the second photoresistor R12 and the first end of the fourth resistor R11 is connected to the fifth pin (i.e. pin 20) of the main control chip U2A.

For example, when the intelligent detection device is mounted on the cargo transportation box, since the second detection module is used to detect the illumination condition inside the cargo transportation box, the second detection module must be isolated from the external environment but communicate with the inside of the cargo transportation box. For example, the second detection module can be arranged at the position of the vent hole of the cargo transportation box body, so that the second detection module can be communicated with the inside of the cargo transportation box body through the vent hole.

The working principle of the second detection module in the embodiment of the utility model is as follows:

the second photoresistor R12 is controlled by the main control chip U2A of the main control module outputting a high level from the fourth pin (i.e., pin 14). The high level output by the fourth pin (i.e. pin 14) is connected to the ground through the fourth resistor R11 after passing through the second photoresistor R12, so as to form a loop, and the second photoresistor R12 starts to work. When the light inside the cargo transportation box is darkened, the resistance value of the second photoresistor R12 becomes larger, and the voltage at Lux1 in fig. 7 becomes smaller, so that the voltage data collected by the fifth pin (i.e., pin 20) of the main control chip U2A of the main control module becomes smaller. When the internal light of the cargo transportation box is lightened, the resistance value of the second photoresistor R12 is reduced, and the voltage at the Lux1 position in fig. 7 is increased, so that the voltage collected by the fifth pin (i.e., pin 20) of the main control chip U2A of the main control module is increased. Therefore, according to the principle that the resistance values of the second photoresistor R12 under different illuminance are different, the second detection module outputs corresponding voltage signals to the main control module, and the main control module is used for ADC sampling, so that the illuminance of the interior of the shipment transportation box body can be calculated. And then the illuminance is uploaded to a data center platform, so that the illuminance of the internal environment of the cargo transportation box body can be mastered remotely.

In the embodiment of the present utility model, the second detection module is powered by the output level of the fourth pin (i.e. pin 14) of the main control chip U2A of the main control module, i.e. the fourth pin (i.e. pin 14) of the main control chip U2A is connected to the location lux_con shown in fig. 7. When illuminance detection is required, the main control chip U2A outputs a high level through the fourth pin (namely the pin 14) so as to normally supply power to the second detection module, and then the second detection module can normally work. The power supply mode has the function of reducing the power consumption of the whole intelligent detection equipment; meanwhile, the function of controlling the second detection module through the main control module is also achieved, and the circuit cost is reduced.

In one embodiment of the present utility model, referring to fig. 8, fig. 8 is a circuit diagram of a power module according to an embodiment of the present utility model. Referring to fig. 8, the power module includes a wireless power interface P1 and a rectifying and filtering circuit. The first end of the rectifying and filtering circuit is connected with the wireless power interface P1. The second end of the rectifying and filtering circuit is used for outputting a supply voltage VBAT to supply power for the main control module and the first detection module.

In the embodiment of the present utility model, the wireless power interface P1 may be connected to a battery or other wireless power source. The rectifying and filtering circuit is formed by connecting a plurality of capacitors in parallel. The power module is used for supplying power to the first detection module and the main control module.

Referring to fig. 9, the smart detection apparatus includes a power module 901, a first detection module 902, a second detection module 903, and a main control module 904.
