[0014] Figure 2 It is a structural schematic diagram of the access control device of the utility model. DETAILED DESCRIPTION

[0015] In order to further understand the structure, features and other purposes of the present invention, the preferred embodiments are described in detail with reference to the accompanying drawings as follows. The embodiments described in the drawings are only used to illustrate the technical solution of the present invention and are not intended to limit the present invention.

[0016] like Figure 1 As shown, an explosion-proof digital intercom with identity recognition includes an explosion-proof housing, in which a first narrowband wireless transceiver 1, an intercom controller 2, a button 3, a first programming interface 4, a microphone 5 and a speaker 6 are arranged.

[0017] exist Figure 1 In the explosion-proof digital intercom, the first narrowband wireless transceiver 1 is electrically connected and connected to the intercom controller 2 by signals, and the intercom controller 2 is electrically connected and connected to the button 3 by signals. The first narrowband wireless transceiver 1 is wirelessly connected to the access control device of the explosion-proof area. When the button 3 is pressed, the button 3 transmits an electrical signal to the intercom controller 2, and after receiving the electrical signal, the intercom controller 2 controls the first narrowband wireless transceiver 1 to transmit the intercom information. The access control device of the explosion-proof area can receive the intercom information and identify whether the intercom is an explosion-proof intercom. Therefore, the identity recognition function of the explosion-proof digital intercom is realized by setting the first narrowband wireless transceiver that transmits the intercom information to the access control device. The first programming interface 4 is electrically connected and connected to the intercom controller 2 by signals. The explosion-proof digital intercom is set through the first programming interface 4. For example, the intercom information is set to identify it as an explosion-proof intercom. The microphone 5 and the speaker 6 are respectively electrically connected and connected to the intercom controller 2 by signals to realize the intercom function of the intercom.

[0018] The access control device will only open after it recognizes that the intercom is an explosion-proof digital intercom that can be used to enter the explosion-proof area. The non-explosion-proof intercom cannot control the opening of the access control device by transmitting its information.

[0019] like Figure 2 As shown, the access control device includes a second narrowband wireless transceiver 11 that matches the first narrowband wireless transceiver 1. The access control device communicates wirelessly with the first narrowband wireless transceiver 1 of the intercom through the second narrowband wireless transceiver 11. The second narrowband wireless transceiver 11 is electrically connected and signal-connected to the access control controller 12. The access control controller 12 is electrically connected and signal-connected to the access switch 13. The second narrowband wireless transceiver 11 receives the intercom information transmitted by the first narrowband wireless transceiver 1, and transmits the intercom information to the access control controller 12. The access control controller 12 is used to identify the intercom information, and after successful identification, controls the access switch 13 to open, so as to open the access control device.

[0020] In addition, after successfully identifying the intercom information, the access control device can also control the second narrowband wireless transceiver 11 to transmit a feedback signal to the first narrowband wireless transceiver 1 of the intercom, and then the intercom controller 2 controls the speaker 6 to emit a prompt tone for the access control device to be turned on.

[0021] exist Figure 2 In the embodiment, the access control controller 12 is also electrically and signally connected to the access control speaker 14. When the access control controller 12 fails to identify the intercom information, the access control controller 12 controls the access control speaker 14 to sound an alarm, thereby realizing that when the intercom information is unsuccessful, the access control device prompts that the intercom is a non-explosion-proof intercom. The access control speaker 14 can also sound a prompt tone for the access control device to be turned on when the identification is successful.

[0022] exist Figure 2 In the embodiment, the access controller 12 is also electrically and signally connected to the second programming interface 15.
