Safe/non-safe statesThe state of security or non-security in the present invention refers to the state of the displayed merchandise, especially refers to the state of relationship between the displayed merchandise and the anti-theft device when the anti-theft device is installed, generally speaking, the merchandise is in the state that we consider it not to be stolen, called the security state, we consider the possible stolen state, called the non-security state, whether the anti-theft measure is intact, whether the displayed merchandise is under the protection of the anti-theft measure, if so, we consider it is the security state, if not, we consider it is the non-security state, that is, this security or non-security state can be the one relative to the anti-theft measure, for example, the anti-theft measure is to keep the displayed merchandise connected with the charging interface all the time, then the sensor detects the charging interface, whether it is connected with the merchandise all the time, if yes, the system is in a safe state, and if the connection is disconnected, the system is in a non-safe state; or, if the theft prevention measure is to keep the article in a charged state all the time, the sensor detects whether the charging cable of the article keeps power transmission, and if so, is in a safe state, and if not,then it is in an unsafe state; or, if the anti-theft measure is that the commodity is clamped by the clamping device, the sensor detects whether the commodity is in the clamping space or whether the commodity is in contact with or installed on the clamping device, if so, the commodity is in a safe state, and if not, the commodity is in a non-safe state; and so on.

Sensor with a sensor elementThe sensor of the present invention is a sensor for sensing a signal or a state, and the sensor is used for merchandise security, i.e. merchandise theft prevention, and the sensor of the present invention can be a sensing circuit, a device with a sensing element, or an element with a sensing function integrated on a connector, and the sensor can sense the signal and determine whether the merchandise is in a safe state or not through the signal. In the present invention, the sensor may be connected to the commodity. In fact, in the field of theft protection of goods, sensors are a widely used prior art, and generally speaking, elements capable of sending out a security signal indicating whether goods are in a safe or non-safe state may be called sensors.

Alarm device/siren/alarmIn the field of merchandise theft prevention, an alarm device is also a common theft prevention device, the alarm device is mainly used for performing alarm operation according to a safety signal sent by a safety device/a sensor/a cable and the like, a typical example of the alarm device is an alarm for sending an alarm prompt sound to prompt staff in a sales place that a merchandise may be in a safe or non-safe state. Generally speaking, this kind of alarming function of alarm device can be said to send alarm signal, and alarm signal for example warning prompt tone still can include light signal sometimes, is called audible-visual annunciator, the utility model discloses do not make improvement to the function and the principle of alarm device, the utility model discloses the improvement is circuit element and structure among the alarm device.

Safety deviceThe safety device of the utility model can comprise a traditional commodity anti-theft device, such as an anti-theft device, an anti-theft host, an alarm, and the like, and can also comprise other tracking devicesThe main function of the security device is to determine whether the merchandise is in a safe state, and if not, to issue a corresponding security prompt, such as an alarm or a security signal. This device can be an independent hardware, also can be with other components, for example the overall structure that sensor and alarm device combined, and safety device's main effect plays certain effect in certain link or certain several links of guaranteeing commodity safety, as long as can play the device of this kind of effect, we can all be called the utility model discloses a safety device to safety device is a concept for being known and applied in the trade in commodity theftproof field, the utility model discloses need not to change safety device's function and principle, only provides a safety device that has changed in the structure.
