Abstract
Description
Technical Field
[0001] This utility model relates to the field of wireless data collection, and in particular to a wireless data acquisition device. Background Technology
[0002] Currently, merchants typically rely on manual statistics to know the status of items on their shelves, such as the number of items sold (i.e., the number of times an item has been retrieved) and whether an item has been sold out (i.e., the shelf vacancy rate). This manual statistical method is relatively inefficient; it also cannot track the time it takes for customers to retrieve items each time; and it is not conducive to conducting comprehensive data statistics for merchants to accurately analyze customer preferences.
[0003] In view of the above problems, it is necessary to study a wireless data acquisition device for collecting the number of times goods are acquired and the time of each acquisition, and for wireless transmission to send the data to a cloud server for statistical analysis and processing. Utility Model Content
[0004] The purpose of this invention is to provide a wireless data acquisition device for collecting data on the number of times goods are acquired and the time of each acquisition, and for wireless transmission to send the data to a cloud server for statistical analysis.
[0005] To achieve the above objectives, the solution of this utility model is:
[0006] A wireless data acquisition device includes a metering unit, a control unit, and a power supply unit. The power supply unit supplies power to the metering unit and the control unit, and the control unit has a wireless transmission function. The metering unit includes a resistor R1 and a photodiode D1. The first end of the resistor R1 is connected to the power supply terminal of the metering unit, the second end of the resistor R1 and the positive terminal of the photodiode D1 are connected to the output terminal of the metering unit, the negative terminal of the photodiode D1 is connected to the ground terminal of the metering unit, the power supply terminal of the metering unit is connected to the output terminal of the power supply unit, the ground terminal of the metering unit is grounded, and the output terminal of the metering unit is connected to the control unit.
[0007] The control unit uses a Bluetooth communication module U1 or a WiFi communication module.
[0008] The Bluetooth communication module U1 is model number BM-1010.
[0009] The power supply terminal of the metering unit is connected to the output terminal of the power supply unit via an electronic switch unit. The input terminal of the electronic switch unit is connected to the output terminal of the power supply unit. The output terminal of the electronic switch unit is connected to the power supply terminal of the metering unit. The control terminal of the electronic switch unit is connected to the control unit.
[0010] The electronic switching unit includes a MOS transistor Q1, the drain, source, and gate of which are respectively connected to the input, output, and control terminals of the electronic switching unit.
[0011] The power supply unit is a battery-powered unit.
[0012] The power supply unit includes a battery BAT1 and a diode DD1. The positive terminal of the battery BAT1 is connected to the positive terminal of the diode DD1, the negative terminal of the diode DD1 is connected to the output terminal of the power supply unit, and the negative terminal of the battery BAT1 is grounded.
[0013] The power supply unit also includes battery BAT2, battery BAT3, diode DD2 and diode DD3. The positive terminal of battery BAT2 is connected to the positive terminal of diode DD2, the positive terminal of battery BAT3 is connected to the positive terminal of diode DD3, the negative terminals of diode DD2 and diode DD3 are connected to the output terminal of the power supply unit, and the negative terminals of battery BAT2 and battery BAT3 are grounded.
[0014] The batteries BAT1, BAT2 and BAT3 are button batteries.
[0015] The output voltage of the power supply unit is 3V.
[0016] After adopting the above scheme, the wireless data acquisition device of this utility model can be used to collect the number of times goods are acquired and the time of each acquisition. When a user acquires an item, the user will block the photodiode D1 of the measuring unit once, thereby causing the output level of the measuring unit to change once, so that the control unit knows that the item has been acquired once. In addition, the control unit can obtain the time of each acquisition by timing the duration of the output level of the measuring unit. In this way, this utility model can collect the number of times goods are acquired and the time of each acquisition by cooperating with the measuring unit. In addition, the control unit has a wireless transmission function, so the control unit can send the number of times goods are acquired and the time of each acquisition to the cloud server in real time for data statistical analysis and processing, so that users can obtain the status of goods and understand user preferences in a timely manner through the cloud server. Attached Figure Description
[0017] Figure 1 This is the circuit schematic diagram of this utility model. Detailed Implementation
[0018] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0019] like Figure 1As shown, this utility model discloses a wireless data acquisition device, which includes a metering unit, a control unit, and a power supply unit. The power supply unit supplies power to the metering unit and the control unit, and the control unit has a wireless transmission function. The metering unit includes a resistor R1 and a photodiode D1. The first end of the resistor R1 is connected to the power supply terminal of the metering unit, the second end of the resistor R1 and the positive terminal of the photodiode D1 are connected to the output terminal of the metering unit, the negative terminal of the photodiode D1 is connected to the ground terminal of the metering unit, the power supply terminal of the metering unit is connected to the output terminal of the power supply unit, the ground terminal of the metering unit is grounded, and the output terminal of the metering unit is connected to the control unit. When the photodiode D1 receives light and is turned on, the output terminal of the metering unit outputs a low-level signal; when the photodiode D1 does not receive light and is turned off, the output terminal of the metering unit outputs a high-level signal.
[0020] This invention's wireless data acquisition device can be used to collect data on the number of times goods are acquired and the time of each acquisition. When a user acquires an item, the user blocks the photodiode D1 of the measuring unit once, causing the output level of the measuring unit to change once. This allows the control unit to detect that the item has been acquired once. Furthermore, the control unit can obtain the time of each acquisition by timing the duration of the output level of the measuring unit. Thus, this invention, through the cooperation of the control unit and the measuring unit, can collect data on the number of times goods are acquired and the time of each acquisition. In addition, the control unit has a wireless transmission function, allowing it to send the number of times goods are acquired and the time of each acquisition to a cloud server in real time for data statistical analysis and processing. This enables users to obtain the status of goods and understand user preferences through the cloud server.
[0021] In this embodiment of the invention, the control unit employs a Bluetooth communication module U1, specifically the BM-1010 Bluetooth communication module from Shanghai Zhixiang Technology Co., Ltd. It should be noted that the control unit is not limited to using the Bluetooth communication module U1; it can also employ a WiFi communication module. The control unit establishes communication with the cloud server through a gateway.
[0022] In an embodiment of this invention, the power supply terminal of the metering unit can be connected to the output terminal of the power supply unit via an electronic switch unit. The input terminal of the electronic switch unit is connected to the output terminal of the power supply unit, and the output terminal of the electronic switch unit is connected to the power supply terminal of the metering unit. The control terminal of the electronic switch unit is connected to the control unit. When the wireless data acquisition device of this invention is not in use, the control unit controls the electronic switch unit to turn off, thereby de-energizing the metering unit and reducing power consumption. When the wireless data acquisition device of this invention is in use, the control unit controls the electronic switch unit to turn on, thereby energizing the power supply unit to supply power to the metering unit. The electronic switch unit may include a MOSFET Q1, the drain, source, and gate of which are respectively connected to the input terminal, output terminal, and control terminal of the electronic switch unit.
[0023] In embodiments of this invention, the power supply unit is a battery-powered unit, meaning that this invention uses a battery to power the control unit and the metering unit. Specifically, the power supply unit may include a battery BAT1 and a diode DD1. The positive terminal of battery BAT1 is connected to the positive terminal of diode DD1, the negative terminal of diode DD1 is connected to the output terminal of the power supply unit, and the negative terminal of battery BAT1 is grounded. Diode DD1 prevents reverse connection of battery BAT1. Further, the power supply unit may also include batteries BAT2 and BAT3, diodes DD2 and DD3. The positive terminal of battery BAT2 is connected to the positive terminal of diode DD2, the positive terminal of battery BAT3 is connected to the positive terminal of diode DD3, the negative terminals of diodes DD2 and DD3 are connected to the output terminal of the power supply unit, and the negative terminals of batteries BAT2 and BAT3 are grounded. Thus, batteries BAT1, BAT2, and BAT3 improve the battery life of the power supply unit. Batteries BAT1, BAT2, and BAT3 can be button batteries, and the output voltage of the power supply unit can be 3V.
