Embodiment 1

[0041] like figure 1 , figure 2 , image 3 The illustrated embodiment is a digital product display device, including a housing, the housing includes a base 1, a bracket 2 mounted on the base, and a bracket 3 positioned at the upper end of the bracket; the bracket includes an insert 31 1. A cylinder 32 with an open upper end on the insert and a supporting plate 33 provided on the cylinder, the upper end surface of the support arm is an inclined surface inclined forward, and the insert is inserted into the upper part of the support arm;

[0042] The insert is connected to one end of the metal rope 4, and the other end of the metal rope is connected to the wire take-up device 5 inside the support arm; the cylinder is provided with a first main control chip 6, a contact switch 7 and a side wall of the cylinder. The charging port 8, the contact switch passes through the hole provided on the supporting plate and is exposed outside the outer surface of the supporting plate.

Embodiment 2

[0054] The current detection device in Embodiment 2 is a current sensor provided on the charging line, and the current sensor is electrically connected to the first main control chip. Other structural parts in Embodiment 2 are the same as in Embodiment 1.

[0055] like Image 6 As shown, all steps in embodiment 1 are included in embodiment 2, and also include the following steps:

[0056] Step 500, setting the interval for sending digital signals in the first main control chip, when the second main control chip has not received the digital signal after 3 times the interval, it means that the metal rope is cut off and the digital signal cannot be sent; The second main control chip controls the alarm to send out sound and light alarm information to alarm.

Abstract

The invention discloses a digital product display unit and a method for controlling the same. The digital product display unit comprises a shell; the shell comprises a base, a support arm and a bracket, the support arm is arranged on the base, and the bracket is arranged at the upper end of the support arm; the bracket comprises an insertion piece, a barrel and a support plate, the barrel is arranged on an opening at the upper end of the insertion piece, the support plate is arranged on the barrel, the upper end surface of the support arm is a forwardly oblique plane, and the insertion piece is inserted into the upper portion of the support arm; the insertion piece is connected with one end of a metal rope, and the other end of the metal rope is connected with a take-up device arranged inside the support arm; and a first main control chip, a contact switch and a charging port are arranged in the barrel, the charging port extends out of a side wall of the barrel, the first main control chip is electrically connected with the metal rope, and a current detecting device is arranged on a charging wire connected with the charging port. The digital product display unit and the method have the advantages that a digital product placed on the digital product display unit can be comprehensively protected against thievery, transmitted alarm signals are stable and reliable, and false alarm is prevented.

Description

technical field [0001] The invention relates to the field of digital display equipment, in particular to a digital product display capable of alarming various abnormal situations and a control method thereof. Background technique [0002] A digital product display is a device used to display digital products. Digital products such as mobile phones and computers are relatively expensive. How to prevent the digital products placed on the digital product display from being stolen is a problem that the digital product display needs to solve. [0003] The usual digital product display is equipped with an abnormal alarm function. When the contact switch on the supporting board of the digital product display is turned on, it means that the digital product is separated from the supporting board. According to the action of the contact switch, it is judged whether the digital product is stolen. [0004] The alarm control method has the disadvantage of being single and unable to alarm...
