Fig. 2 is the circuit diagram of the utility model based on the coalcutter phonetic warning system of CAN bus.
Embodiment
Shown in Fig. 1-2, the utility model mainly comprises based on the coalcutter phonetic warning system of CAN bus: CAN bus transceiver, primary controller, voice storage module, power amplifier module and power module, and concrete outside installation is as follows:
The CAN bus transceiver is connected with primary controller respectively with voice storage module, and the output terminal of voice storage module connects power amplifier module, and the output terminal of power amplifier module connects explosion-proof loudspeaker.Total system have four lead-in wire: CANH, CANL ,+24V and GND.
As shown in Figure 2, in the present embodiment, CAN bus transceiver U1 adopts SN65HVD230, primary controller U2 adopts C8051F040, voice storage module U4 adopts ISD4002-120P, and power module U3 adopts LM2576, and power amplifier module adopts TDA2030, the concrete annexation of each several part is as follows: the reception of CAN transceiver SN65HVD230 receives with the CAN transmission with the CAN of primary controller C8051F040 respectively with transmitting terminal and is connected, and realizes the transmission of CAN signal; Port P0.2～P0.6 of primary controller C8051F040 respectively with ISD4002-120P /INT ,/SS, MOSI, MISO, SCLK be connected, realization is to the control of voice storage chip ISD4002-120P, and select to be stored in voice signal in the voice storage chip by corresponding C AN signal, be connected with TDA2030 by the AUDOUT pin, the power amplification of the signal of realizing, and export by loudspeaker.
The CAN bus is adopted in the coalcutter communication, and the sensor external information of coalcutter primary controller by installing, and testing result sent on the CAN bus according to agreement, receiving the various failure messages of coalcutter by the CAN bus, the CAN bus transceiver is connected with the CAN bus.Like this, phonetic warning system just can send warning message according to the data on the CAN bus.
