Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1: an article safety protection device and system comprises a touch system, a control system, an alarm system and a power supply 6.
The touch system comprises a touch combination key 3, a surface sensing device 7, a gravity sensor 8 and a horizontal sensor 9, the control system comprises a control combination key 1, and the alarm system comprises an alarm 5.
The touch combination key 3, the alarm 5 and the power supply 6 are sequentially connected in series to form an upper loop.
The surface sensing device 7, the gravity sensor 8 and the horizontal sensor 9 are connected in parallel to form a triggering branch circuit, and the triggering branch circuit is sequentially connected with the control combination key 1, the alarm 5 and the power supply 6 in series to form a lower loop.
All the electric elements left in the upper loop and the lower loop after the trigger branch is removed form a plurality of control alarm branches, and the control alarm branches are connected in parallel and then connected in series with the trigger branch.
The control combination key 1 comprises 4 contacts at the front, the back, the left and the right, namely 4 contacts marked with a, b, c and d in the attached figure 1. The touch combination key 3 comprises 4 touch surfaces, namely 4 touch surfaces marked A, B, C, D in figure 1, in front, back, left and right. And 4 contacts of the control combination key 1 are arranged right above 4 contact surfaces of the touch combination key 3 and are in one-to-one correspondence.
The control combination key 1 further comprises a first conductive column 2, a setting switch and a key surface, wherein the first conductive column 2 is arranged at the center of the 4 contacts on the control combination key 1. The first conductive column 2 is connected with an alarm 5 in series through a conducting wire and then connected to one pole of a power supply 6. One end of the surface sensing device 7, the gravity sensor 8 and the horizontal sensor 9 which are connected in parallel are connected to the other pole of the power supply 6, and the other end of the surface sensing device is respectively communicated with 4 contacts on the control combination key 1 through leads. The number of setting switches is 4, and the setting switches are labeled k1, k2, k3, k4 in fig. 1. And the 4 setting switches respectively and independently control the 4 contacts a, b, c and d on the combination key 1 and the first conductive column 2 to be mutually electrically communicated or opened. The center of the key surface is electrically connected with the first conductive pillar 2, and the periphery is suspended and arranged right above the 4 contacts a, b, c, d of the control combination key 1.
When the setting switch controls 4 contacts on 1 or more than 1 control combination keys 1 to be electrically communicated with the first conductive column 2, the communicated contacts are used as the set contacts, the structure of the setting switch sequentially comprises a conductive layer and an insulating layer from top to bottom, and after the setting switch is set, the setting switch is arranged under the contacts of the control combination keys 1 and is arranged right above the contact surfaces of the touch combination keys 3, the setting switch only isolates one corresponding point on the corresponding contact surfaces right below the contacts, and an upper loop can be conducted to alarm when the contacts and the key surfaces right above the contact surfaces are not correctly pressed.
The touch combination key 3 further comprises a second conductive post 4. The second conductive pillar 4 is disposed coaxially with and electrically connected to the first conductive pillar 2. The second conductive column 4 is connected with the alarm 5 in series through a conducting wire and then connected to one pole of the power supply 6. The 4 touch surfaces on the touch combination key 3 are respectively connected to the other pole of the power supply 6 through wires.
When the user does not use the articles, the set points on the plurality of control alarm branches are set in sequence through the setting switches. The structure of the setting switch is sequentially a conducting layer and an insulating layer from top to bottom. And after the setting switch is set, the setting switch is arranged right below the contact of the control combination key 1 and right above the contact surface of the touch combination key 3.
Here, assuming that the set contacts on one of the control alarm branches are the a contact and the b contact, the two contacts c and d on the control combination key 1 are the non-set contacts. At this time, the setting switch k1 communicates the a-contact with the first conductive pillar 2, and the setting switch k2 communicates the b-contact with the first conductive pillar 2.
Based on the above assumption, when the user correctly presses the key surfaces directly above the a-contact and the b-contact when the user needs to unlock, the set contacts are released by the k1 and k2 being flicked. At this time, since the insulating layers of the setting switches k1 and k2 isolate the second conductive column 4 in the upper loop from the communication between the a contact surface and the B contact surface of the touch combination key 3 directly below the a contact and the B contact, the upper loop cannot be connected for alarming at this time, and since the set points, namely the a contact and the B contact, on the control combination key 1 in the lower loop are released after the upper loop is correctly pressed, the lower loop cannot be connected for alarming at this time.
Based on the above assumption, when the key surfaces directly above the a-contact and the b-contact are not correctly pressed, the set contacts are not released because k1 and k2 are not flicked. Because k1 and k2 only isolate two corresponding contacts on the A touch surface and the B touch surface which are corresponding to the positions right below the a contact and the B contact, and do not isolate the rest contacts on the A touch surface and the B touch surface, when the key surface right above the a contact and the B contact is not correctly pressed, the upper loop can be conducted to alarm, and the condition that articles are stolen is prompted to a user or the user is prompted to press the key surface incorrectly.
Based on the above assumption, under the condition that the key surface is not pressed, when one or more of the surface sensing device 7, the gravity sensor 8 and the horizontal sensor 9 in the triggering branch are triggered, the lower loop is conducted, and at the moment, the alarm 5 can also send out an alarm signal to prompt a user that the article is stolen. Wherein, the surface sensing device 7 can be triggered to be conducted when being pressed; the gravity sensor 8 is triggered and conducted when the device moves up and down; the level sensor 9 is triggered to be conducted when the device is not in a horizontal state after being moved, and the key surface is a metal key surface with an insulating coating coated on the outer surface.
The control combination key 1 is a multidirectional key with an automatic rebound function.
The surface sensing device 7 is disposed on the surface of the device.
Both the gravity sensor 8 and the level sensor 9 are arranged inside the device.
The alarm 5 is a sound and light alarm device.
The surface sensing device 7 sequentially comprises a surface layer 701, a middle layer 702 and a base layer 703 from top to bottom, the surface layer 701, the middle layer 702 and the base layer 703 are arranged in a suspended mode through elastic insulation supports, the surface layer 701 and the base layer 703 are made of conductive materials, the middle layer 702 is made of elastic materials containing conductive material particles, when the surface sensing device 7 is pressed and touched, electric signals are transmitted to the base layer 703 through the middle layer 702 from the surface layer 701, one end of the surface layer 701 is connected with the negative pole of the power supply 6, and one end of the base layer 703 is connected with the positive pole of the power supply 6.
The number of the control alarm branches is 20. When the user uses the device, the user needs to correctly press the set contacts on the 20 control combination keys 1 in sequence to relieve the alarm.
The invention has the functions of preventing the articles from being stolen and lost and preventing the system from being damaged, and solves the problem of article safety protection through simple and convenient operation. The invention can realize the function of misoperation alarm. When a user uses an article, the set contact can be disconnected by pressing the corresponding set contact, so that an alarm signal generated by the trigger branch circuit is relieved, and the operation is simple and convenient. Compared with the prior art, the code element is added, the code length is reduced, the operation is simplified, and the safety performance is ensured.
