Abstract
The utility model relates to a multimedia player RS485 signal intrinsically-safe processing device for mining. An RS485 signal processing unit, a non intrinsically safe RS485 interface A, an intrinsically safe RS485 interface B and a DC power supply are connected to form the device; the RS485 signal intrinsically-safe processing device is installed in a flameproof shell; the RS485 signal processing unit through the non intrinsically safe RS485 interface A is connected with an industrial personal computer in the flameproof shell, and is connected with a 7-core flameproof cavity penetrating terminal through the intrinsically safe RS485 interface B; and an intrinsically safe interface C is placed in an intrinsically safe box and is connected with the7-core flameproof cavity penetrating terminal. The beneficial effects of the utility model are that: the isolation between the non intrinsically safe RS485 interface and the intrinsically safe RS485 interface on the device; when the RS485 interface on the industrial personal computer of the mine-used flameproof and intrinsically safe multimedia player is short-circuited, the intrinsically sage RS485 interface C in the intrinsically safe box does not generate sparks, so as to guarantee the safety of the RS485 intrinsically safe interface when used in the inflammable and explosive situations in mines.

Summary of the invention
The purpose of this utility model is, a kind of essential safe type treating apparatus of the RS485 signaling interface with signal isolation features is provided, and the flame proof of realizing between mine flameproof and intrinsic safety type multimedia player by this treating apparatus is connected.
The purpose of this utility model is achieved through the following technical solutions: mining multimedia player RS485 signal essential safe type treating apparatus, it is characterized in that, connected and composed by RS485 signal processing unit, non-intrinsically safe safety-type RS485 interface A, essential safe type RS485 interface B and direct supply;
RS485 signal essential safe type treating apparatus is arranged in explosion-proof casing, RS485 signal processing unit connects the industrial computer in explosion-proof casing by non-intrinsically safe safety-type RS485 interface A, wear chamber terminal by essential safe type RS485 interface B connection-core flame proof, essential safe type interface C is placed in intrinsic safety case, and essential safe type interface C connects 7 core flame proofs and wears chamber terminal.
The beneficial effects of the utility model: 1. utilize this RS485 signal essential safe type treating apparatus, can realize the isolation between the essential safe type RS485 interface on non-intrinsically safe safety-type RS485 interface and this device on this essential safe type treating apparatus being connected with the RS485 interface on mine flameproof and intrinsic safety type multimedia player industrial personal computer component.
2. essential safe type RS485 interface B wears chamber terminal by 7 core flame proofs and is connected with intrinsic safety case essential safe type RS485 interface C; like this RS485 interface on mine flameproof and intrinsic safety type multimedia player industrial personal computer component be short-circuited and other situation under; can not cause intrinsic safety case essential safe type RS485 interface C flashing; ensure the security that essential safe type RS485 interface uses under inflammable, the explosive complex situations of mine, also protected the essential safe type peripheral hardware being connected with essential safe type RS485 interface C.
3. can be in the situation that mine flameproof and intrinsic safety type multimedia player system be charged, in intrinsic safety case, pass through essential safe type RS485 interface C, the essential safe type peripheral hardware that direct connection possesses RS485 communication function uses, facilitate user in the situation that system is charged, directly connection or disconnection possess the essential safe type peripheral hardware of RS485 communication function.
