In this embodiment, the signal source generating module 104 is configured to generate a preset signal and send the preset signal to the first external interface 101 and the signal determining module 104; a first external interface 101 for transmitting the preset signal to an external signal processing device 20; the second external interface 102 is used for receiving an input signal input from the outside and sending the input signal to the signal judgment module 104; the signal judgment module 104 is used for judging whether the preset signal is the same as the input signal or not under the condition of receiving the input signal, and if so, triggering the alarm module 105 to alarm for theft prevention; and the alarm module 105 is used for performing anti-theft alarm according to a preset mode.
In this embodiment, the preset signal generated by the signal source generating module 104 may be a random signal, and may be a signal generated according to a preset strategy, for example, a continuous waveform or a sequence of alternating high and low levels, a sine wave with a preset period and a periodic variation, or a waveform with every other period sequentially varies according to a preset waveform list, or a signal is generated randomly with every other period. Further, the preset signal includes: digital signals (e.g., 0101010) and analog signals (sine wave, square wave, triangle wave, etc. waveforms). In this embodiment, the waveform of the preset signal and the strategy of the change are not limited, and any one of the digital signal and the analog signal may be generated in this embodiment.
In this embodiment, the determining whether the signals are the same by the signal determining module 104 includes: if the digital signals are digital signals, judging whether the digital signals represented by the high and low levels of the digital signals are consistent, if so, for example, both the digital signals are 0101010, the two signals are the same, otherwise, the two signals are different; if the signals are analog signals, judging whether the waveforms of the two signals can be completely overlapped, if so, judging that the two signals are the same, otherwise, judging that the two signals are different.

The method is as follows: and carrying out signal deformation on the preset signal.
In this manner, for example, the signal change processing module may include electronic components such as a resistor and a capacitor, and the preset signal changes in an analog manner after passing through the electronic components, for example, a square wave is changed into a sine wave.

In this embodiment, the signal decision module 104 firstly processes the preset signal with the same signal processing policy negotiated with the signal processing device 20, for example, all signals are reversely converted, and under a normal condition, the signal processed by the signal decision module 104 and the input signal received by the second external interface 102 should be the same, and the input signal should be a signal processed by the external signal processing device 20 with the negotiated same signal processing policy. However, if the comparison result is different, it indicates that the external signal processing apparatus 20 has been disconnected from the device management apparatus 10, and the attacker is performing theft, for example, when a wire is connected between the first external interface 101 and the second external interface 102, the input signal will be different from the signal processed by the signal decision module 104.

As an optional implementation manner of this embodiment, the method provided in this embodiment further includes: and the equipment management device performs anti-theft alarm according to a preset mode under the condition that the input signal is not received. That is, when the attacker directly steals the device management apparatus and disconnects the device management apparatus 10 from the signal processing apparatus 20, the device management apparatus 10 does not receive the signal, and thus determines that the device management apparatus is stolen and gives an alarm. In this embodiment, the device management apparatus may generate the preset signal according to a predetermined period, for example, once every 5 seconds, at this time, if the device management apparatus has not received the input signal within 5 seconds, it determines that the device management apparatus has not received the input signal at this time, and immediately alarms.
As an optional implementation manner of this embodiment, the alarming according to a preset manner includes at least one of the following manners:
the first method is as follows: the equipment management device transmits the anti-theft alarm information to a third party monitoring platform in a wired or wireless communication mode;
in this aspect, the device management apparatus has a communication function, and the wireless aspect may include: bluetooth, WIFI, NFC, infrared or RFID and the like; the wired mode may include: the device management device can be notified to a remote user when an attacker steals the device management device by means of USB, audio RJ11, RJ45 or a serial port, so that the user can know that the device management device is stolen as soon as possible and take measures as soon as possible to reduce loss.
The second method comprises the following steps: the equipment management device gives out light and alarms;
in this manner, the device management apparatus may include a light emitting diode with which to illuminate an alarm.
The third method comprises the following steps: the device management apparatus sounds an alarm.
In this manner, the device management apparatus may include a buzzer, with which an alarm is sounded.
Through the anti-theft method applied to the equipment management device, the theft action of an attacker can be found quickly, an alarm is given, a user can know that the equipment management device is stolen in time, corresponding measures are taken, and personal loss is reduced.
Example 4
The embodiment provides an anti-theft method applied to a device management device. The method is applied to the antitheft system of the device management apparatus in embodiment 1. As shown in fig. 5, the method includes steps S201 to S205, in which:
steps S201 to S204 are the same as steps S101 to S104, and the present embodiment differs from embodiment 3 in that: in this embodiment, step S205 is: and under the condition that the equipment management device receives the input signal, the equipment management device adopts the same signal processing strategy as the signal processing device to carry out conversion processing on the preset signal, judges whether the processed signal is the same as the input signal or not, and alarms according to a preset mode if the processed signal is different from the input signal.
In this embodiment, the device management apparatus first processes the preset signal with the same signal processing policy negotiated with the signal processing apparatus, for example, all signals are reversely transformed, and in a normal case, the signal processed by the device management apparatus should be the same as the received input signal, and the input signal should be a signal processed by the external signal processing apparatus with the negotiated same signal processing policy. However, if the comparison result is different, it indicates that the signal processing apparatus has been disconnected from the device management apparatus 10, and the attacker is performing theft, for example, when a wire is connected between the first external interface 101 and the second external interface 102, the input signal will be different from the signal processed by the device management apparatus.
Through the anti-theft method of the equipment management device provided by the embodiment, the theft action of an attacker can be quickly found, and then an alarm is given, so that a user can timely know that the equipment management device is stolen, and then corresponding measures are taken, and personal loss is reduced.
