This is explained with reference to a specific example.

The embodiment relates to the level detection of the low-power-consumption Bluetooth and the input/output (GPIO for short) based on a single chip microcomputer.

To bluetooth low energy BLE: bluetooth Low Energy (BLE), also known as Bluetooth Low energy (Bluetooth), is a personal area network technology designed and sold by the Bluetooth technical alliance, and is intended to be used for emerging applications in the fields of medical care, exercise and fitness, beacons, security, home entertainment and the like. Bluetooth low energy is intended to significantly reduce power consumption and cost while maintaining equivalent communication range compared to classical bluetooth.

Level detection based on singlechip GPIO: the pin of the single chip microcomputer GPIO is controlled by a program and can be freely used, and the GPIO can be used as General Purpose Input (GPI), General Purpose Output (GPO) or General Purpose Input and Output (GPIO). For an input, the pin potential can be determined high or low by reading some register.

GPIO has the following advantages:

low power consumption: GPIO has much lower power loss (about 1 muA-20 muA).

And (5) small packaging: GPIO devices provide minimum package size

The cost is low: cost is determined and singlechip

And (3) rapid development: no extra code and document need to be written, and no maintenance work is needed.

The portable bag in the embodiment can be vertically implanted with the Norman conducting wires from top to bottom, and the number of the conducting wires can be determined by actual conditions according to the size, the material and the like of the portable bag.

The upper end of the wire (the top end of the backpack) is connected with the power supply module in a unified way, and a stable level is provided for the single chip microcomputer GPIO (level detection unit) at the lower end (the bottom end of the backpack).

The singlechip is placed at the bottom end of the backpack, and the lower end of each wire is connected with the GPIO of the singlechip.

The positions of the power supply and the single chip microcomputer can be exchanged without limitation. For example, as shown in fig. 2, the arrows in fig. 2 are represented as wires, and the direction of the arrows is represented as the direction of current flow.

Since all wires are distributed vertically throughout the backpack and are independent.

All GPIOs of the singlechip are set as input when in normal, and all GPIOs can detect a high level signal at the moment.

When the backpack is cut by the knife, the cut part can cause the corresponding conducting wire to be disconnected, so that the corresponding GPIO can not detect the original high-level signal and can detect the low-level signal.

At this time, the occurrence of the cutter theft can be judged.

In the embodiment, whether the zipper is disconnected or not can be determined by detecting the level signal. The metal zipper is a conducting wire, one end of the metal zipper is connected with a power supply, and the other end of the metal zipper is connected with the GPIO of the single chip microcomputer. When normal, the zipper is completely closed, and the corresponding GPIO can detect a high-level signal. When the zipper is illegally opened, the zipper is not completely connected, and the corresponding GPIO cannot detect the original high-level signal. At this time, the zipper theft can be judged. The detection time may be set by the user in this embodiment. If the user needs to rest on the vehicle, the second level signal needs to be detected in real time from the first time to the second time. The detection may be cancelled after waking up. So as not to send the second message by itself using the zipper.

The direction in which the theft occurred can be determined from the direction in which the portable bag was damaged. Because each wire is detected by an independent GPIO, each wire has certain position attribute. When the left side of the backpack is cut off by the knife, the wire on the left side is also cut off at the same time, and the corresponding GPIO cannot detect a high-level signal, so that the user can know that the left side of the user is stealing. The user may preset the orientation of the portable bag to determine the orientation or location of each individual GPIO.

The location information is transmitted through BLE broadcasting through specific data information, and the BLE information can be received by users and other people through mobile phones or other BLE devices.

The above single chip microcomputer may be an integrated circuit SoC chip with a low power consumption bluetooth BLE function, such as RTL8762C, nRF52 series, MTK7697, and the like, such an SoC has a BLE function in addition to the basic functions of a general single chip microcomputer, and can communicate with other bluetooth devices according to a BLE protocol, and a broadcast mechanism of BLE is adopted here.

Figure 3 is a broadcast information transmission diagram based on BLE. In the figure, ABCDEFGH in a mobile phone diagram is used as a user backpack, an arrow in the figure 3 is an anti-theft broadcast transmitting direction of BLE, a triangular exclamation mark in the figure 3 is a backpack position where theft occurs, and an anti-theft data format of BLE broadcast is an LTV format (Length-Type-Value) to form a BLE AD Structure, and the Length of the BLE AD Structure is less than 31 bytes. The anti-theft data format is shown in fig. 4.

Type data format: the entire broadcast data needs to have the following types of AD Structure

Example of broadcast data: 0x 070 xF 10 x 000000010 x 030 xF 10 x 010 x 030 xF 20x 120x 030 xF 20x 210 x 030 xF 30 x 020 x 070 xF 40 xC 00000000 x 030 xF 50 x00

The specific meanings are as follows:

the system flow is shown in fig. 5.

The anti-theft function in this embodiment may be manually turned on by the user. The user needs to set device parameters (such as device types, colors, materials and the like) when the function is started for the first time, software stores data according to the device parameters set by the user (subsequent users do not need to set again), the SoC initializes corresponding hardware (such as clocks, GPIO, a BLE protocol stack and the like), the SoC detects whether all GPIO levels are normal or not, if normal, the GPIO levels are abnormal continuously detected until the user is manually closed, the theft type is judged according to the ID of the GPIO, data is stolen, broadcast information is constructed according to 4.5.3 according to the device information set by the user before, an alarm is sent through a loudspeaker (the loudspeaker can be a mobile phone loudspeaker) according to the selection of the user, and the SoC sends the constructed BLE broadcast information until the user is manually closed.

Suppose a in fig. 3 steals the user and cuts the left side of the user's backpack with a knife. At the moment, the SoC detects the left side level abnormality through the GPIO level, and anti-theft broadcast data information is constructed through previous user input information. And transmitting the anti-theft broadcast information through BLE. The user mobile phone receives the broadcast information and can judge that the backpack is stolen according to the equipment ID, and can judge that the left side of the backpack is cut off according to the theft type and the theft data, so that the user can quickly lock the suspect A according to the position. The user mobile phone judges whether a loudspeaker is needed to give an alarm according to the user setting, and if so, the mobile phone gives out a sound alarm with large volume. The surrounding person B, C, D, E, F, G, H can know that: your accessory is sending a theft, asking for caution. The suspect is cutting a yellow cortical backpack and please note. Meanwhile, the approximate distance between the theft occurrence place and the mobile phone can be calculated according to the transmission power in the broadcast data and the signal strength received by the mobile phone.
