3 external communications of communication board all adopt isolation method to carry out, and greatly improve the reliability of product.
Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
A kind of intelligent fire is met an urgent need multifunctional communication plate, comprise main control unit, CAN communication unit, externally communication unit, memory cell, clock unit, acoustics unit, keyboard scan unit, liquid crystal display and lamp display unit, main control unit is connected with CAN communication unit, external communication unit, memory cell, clock unit, acoustics unit, keyboard scan unit, liquid crystal display and lamp display unit respectively.External communication unit is connected external communication signal by RS232 with RS485 communication interface, adopts isolation method to realize reliable communication.The communication that this interface is used as external equipment connects, embedded software interface.Also software function can be improved according to the actual needs of client.
CAN communication unit is the CAN communication of enhancement mode, has 2 groups of CAN interface communications, and interface adopts isolation method to carry out communication, greatly improves the reliability of product.Two groups of CAN communication are used as to realize inner communication function, and the reliability of communication is very high.
This communication board is used as controller and uses, and therefore possesses eeprom memory, can store necessary logout, possess storage and display that real-time clock carries out the time simultaneously.This product possesses sound equipment control simultaneously, can connect the sound equipment of 5W/8 Ω, realize the control of 4 kinds of tones.
Main control unit adopts the arm processor of 32 to control, and realizes communication and the control operation of unit in Fig. 1.
Keyboard adopts scan mode to carry out, and maximumly can connect 64 buttons.Scanning adopts 4ms once to scan, and improves reliability and real-time.
This communication board supports the graphic lcd display of 240*64, operation and event can be shown, and coordinates keyboard unit to realize man-machine interaction.
And this communication board can control by connecting lamp, for the state of display lamp.
This communication board adopts independent DC5V to power.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from utility model design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
