the electromagnetic lock control circuit 30 is connected with the MCU detection circuit 20, receives the level signal output by the MCU module and controls whether to output a power supply or not;
the electromagnetic lock 40 is arranged beside the insertion and extraction slot of the OPS module 10; the electromagnetic lock 40 is connected with the electromagnetic lock control circuit 30 to receive the output power supply of the electromagnetic lock control circuit 30; when the electromagnetic lock control circuit 30 has power output, the electromagnetic lock 40 controls the bolt to retract, and the OPS module 10 is allowed to be pulled out; when the electromagnetic lock control circuit 30 has no power output, the electromagnetic lock 40 controls the bolt to extend, and the OPS module 10 is prohibited from being pulled out.
Specifically, the electromagnetic lock 40 includes one or more.
In fig. 1, the electromagnetic locks 40 include two electromagnetic locks 40, and the two electromagnetic locks 40 are symmetrically disposed above and below the OPS module 10, respectively. It will be appreciated that two electromagnetic locks 40 may also be provided to the left and right of the OPS module 10. Two electromagnetic locks 40 are provided to more firmly block the OPS module 10, preventing theft and preventing hot plug. Of course, more than two electromagnetic locks 40 may be provided.
When the electromagnetic lock 40 includes a plurality of electromagnetic locks, the power supply terminals of the plurality of electromagnetic locks 40 are respectively connected to the output power supply of the electromagnetic lock control circuit 30. As can be seen from fig. 1, when the electromagnetic lock 40 includes two electromagnetic locks, the output power of the electromagnetic lock control circuit 30 is connected to the power terminals of the two electromagnetic locks 40 respectively for supplying power.
Specifically, fig. 2 is a circuit diagram of the OPS module 10 of the present embodiment. When the OPS module 10 is powered off, the OPS module 10 outputs a low level signal through an output terminal 48; when the OPS module 10 operates, the OPS module 10 outputs a high level signal through the output terminal 48.
Specifically, referring to fig. 3, in this embodiment, the model of the MCU module is G032103CBR 6. An input end 28 of the MCU module receives the operating state level signal sent by the OPS module 10. At the same time, the other output 29 of the MCU module outputs a level signal opposite to the received level signal to the electromagnetic lock control circuit 30. Specifically, when the electronic device works and the OPS module 10 is shut down, the OPS module 10 outputs a low level signal to the end 28 of the MCU module through the output end 48, and the MCU module outputs a high level signal to the electromagnetic lock control circuit 30 through the output end 29; when the OPS module 10 works, the OPS module 10 outputs a high level signal to the end 28 of the MCU module through the output end 48, and the MCU module outputs a low level signal to the electromagnetic lock control circuit 30 through the output end 29; when the electronic device does not work, the MCU module does not work, and no level information is output to the electromagnetic lock control circuit 30.
Referring to fig. 4, the electromagnetic lock control circuit 30 includes: the circuit comprises a first resistor, a second resistor, an MOS switching tube and a triode; one end of the first resistor and the source electrode of the MOS switching tube are connected with a direct current power supply; the other end of the first resistor is respectively connected with a collector of the triode and a grid of the MOS switch tube; one end of the second resistor is connected with the level signal output by the MCU module, and the other end of the second resistor is connected with the base electrode of the triode; the drain of the MOS switch tube is connected to the power supply terminal of the electromagnetic lock 40.
In this embodiment, the MOS switch tube is a PMOS tube; the triode is an NPN type triode.
After the electromagnetic lock control circuit 30 receives the MCU _ DZ high level signal sent by the MCU module, the MOS transistor is turned on, the 12V _ PL outputs a 12V dc power to the electromagnetic lock 40, the electromagnetic lock 40 operates, the latch retracts, and the OPS module 10 can be normally pulled out. After the electromagnetic lock control circuit 30 receives the MCU _ DZ low level signal sent by the MCU module, the MOS transistor is turned off, no power is output from 12V _ PL, the electromagnetic lock 40 does not operate, and the lock tongue extends out to lock the OPS module 10.
In summary, the present invention includes the following application scenarios:
(1) when the electronic device does not work, the electromagnetic lock control circuit 30 has no power supply to output to the electromagnetic lock 40. According to the principle of the electromagnetic lock 40, when no power is supplied, the lock tongue of the electromagnetic lock 40 automatically extends out and locks the OPS module 10 under the action of a spring, so that the purpose of preventing the OPS module 10 from being stolen when the mobile phone is not started is achieved.
(2) When the whole machine is started, when the OPS module 10 normally works, the OPS module 10 can output a high level signal to the MCU module, when the MCU module receives the high level signal, the MCU module can output a low level signal to the corresponding electromagnetic lock control circuit 30, the electromagnetic lock control circuit 30 does not have a power supply to output the electromagnetic lock 40, at this moment, the electromagnetic lock 40 does not work, the spring bolt extends out to block the OPS module 10, when the OPS module 10 normally works, a user can not pull out the OPS module 10, and therefore hot plugging of the OPS module 10 is avoided.
(3) When the OPS module 10 needs to be pulled out, the OPS module 10 must be shut down first, and after the OPS module 10 is shut down, the signal level of the OPS module 10 self output becomes low, and after the MCU module receives the low level signal, the MCU module will output another high level signal to the corresponding electromagnetic lock control circuit 30, and the electromagnetic lock control circuit 30 outputs power to the electromagnetic lock 40, at this moment, the electromagnetic lock 40 works, the lock tongue retracts, and the screen display prompt can normally pull out the OPS module 10.
In a second aspect, the electronic device of the present invention includes the OPS module anti-theft and anti-hot-plug protection device. The electronic device can be a touch integrated device, an electronic whiteboard and the like.
