Embodiment 1

[0021] Example 1: See Figure 1, Figure 2, Figure 4, Figure 6, Figure 7

[0022] The present embodiment 1 self-service commodity anti-theft system consists of commodity electronic detectors, decoders or unlockers, hand-held detectors, supporting materials, and additional remote control devices 4 and display screens 2.7.

[0023] As shown in Fig. 1, the commodity electronic detector consists of a transmitter 1, a receiver 2 and a soft label or hard label 3 on the commodity. The remote control device 4 is made up of a remote control transmitter 4.1 and a remote control receiving circuit 4.2 mounted on the receiver 2 printed board. The display screen 2.7 is provided with three display lamps 2.71, 2.72, 2.73 indicating the level of interference; at the same time, a power indicator lamp 2.70 is provided, which is the light-emitting diode D2 in FIG. 7 .

[0024] See Fig. 2, be provided with antenna 2.1, high-frequency receiver 2.2, detector 2.3, amplifying comparator 2.4, digital an...

Embodiment 2

[0032] Embodiment 2: See Figure 8

[0033] The only difference between Embodiment 2 and Embodiment 1 is that the digital potentiometer W 4.2 The second type of control circuit 4.23b is used to replace the dedicated integrated block 9511. The second type of control circuit 4.23b is a general type, consisting of a pulse control gate circuit i, a decoding integrated block ii (model CD40193), and a resistor row R 1 -R 16 Composed of the electronic switch iii (model 4067). Access the digital potentiometer W in the amplifying comparator 2.4 (Figure 3-Figure 4) through the IN and OUT interfaces in Figure 8 4.2 The position is connected with pins 11 and 10 of the decoding integrated circuit 4.21 in FIG. 7 through nodes C and D in FIG. 8 respectively.

Embodiment 3

[0034] Embodiment 3: see Figure 9, the only difference between this embodiment 3 and embodiment 2 is the resistor row R 1 -R 16 is in series, while Example 2 resistor row R 1 -R 16 is in parallel. The rest are exactly the same as Example 2.

Abstract

A burglar proof system of self-service commodity is prepared for adding remote control unit and display screen on said system, forming remote control emitter by coding control and modulation oscillation circuit as well as emission circuit, forming remote control receiving circuit by receiving head and decoding integrated circuit and digital potentiometer being used to replace existed mechanical potentiometer, setting said emitter and said receiving circuit at two sides of exit on department store for detecting out stolen commodity.

Description

[0001] (1) Technical field: a self-service commodity anti-theft system and its use method, which is a wireless anti-theft alarm system for commodities. It belongs to alarm device category (G08B), display category (G09F) and remote control regulation category (G05B). (two) background technology: [0002] The existing commodity anti-theft system is an important anti-loss means for shopping malls, supermarkets, clothing stores, etc., and can be equipped with commodity electronic detectors, decoders or unlockers, hand-held detectors, and supporting materials. As shown in Figure 1, the commodity electronic detector is equipped with a transmitter 1 and a receiver 2, which are respectively placed on both sides of the exit of the shopping mall or supermarket. There are soft labels or hard labels 3 on the commodities. Secure with pins or locks. When the customer pays, the cashier decodes the soft label with a decoder or removes the hard tag from the product with an unlocker. After the...
