The embedded multichannel fire-fighting of technical grade remote monitoring transmission equipment
Technical field
The present invention relates to a kind of fire-fighting remote monitoring transmission equipment, the embedded multichannel fire-fighting of particularly a kind of technical grade remote monitoring transmission equipment.
Background technology
It is the technology of core that fire-fighting remote monitoring transmission equipment, traditional design have adopted with the single-chip microcomputer, and by serial line interface transmission fire protection warning information, senior transmission equipment has adopted with single-chip microcomputer+10M Ethernet interface transmission means.Because aspects such as single-chip microcomputer speed is slow, capacity is little, disposal ability is low restriction, just storage after the warning, easy obliterated data in the transmission course, warning message fault such as overflow and happen occasionally, and have caused bigger economic loss to people.
Summary of the invention
Purpose of the present invention just is to provide a kind of system architecture advanced person, transfer of data in real time, efficiently and reliably, simultaneity factor is also integrated based on the audio-video monitoring of Ethernet coffret, the embedded multichannel fire-fighting of the technical grade of complete function remote monitoring transmission equipment can effectively address the above problem.
To achieve these goals, the technical solution used in the present invention is such: the embedded multichannel fire-fighting of technical grade of the present invention remote monitoring transmission equipment, comprise cabinet, the mainboard in the cabinet and the control panel on cabinet surface, also comprise power panel, power panel is connected with mainboard, for mainboard provides power supply, mainboard comprises master chip and extends out the Flash storage chip, master chip adopts CORTEX-M3 to examine 8962 chips, described control panel is provided with independent button and LED display lamp, and independent button is connected with mainboard with the LED display lamp, also is connected with the RS232 interface on the mainboard, jtag interface, RS485 interface and Ethernet interface.
As preferably, described power panel comprises active/standby electro-detection control and the switching device shifter that main electricity/power backup power supply and the main electricity of control/power backup power supply switch.
As preferably, also connect an alarming horn on the described mainboard.
Compared with prior art, the invention has the advantages that: the present invention is specially at the fire-fighting long distance control system, adopt the ARM chip as host CPU, the CORTEX-M3 that adopts examines 8962 chip frequency speeds and reaches 50MHZ, it is the ARM chip of a high integration, low-power consumption, Harvard structure, selected for use serial ports controller and ethernet controller integrated chip to make system design convenient, the high performance processor system that makes is handled in real time in the processing of data with in transmitting; This transmission equipment has adopted multiple task operating system and simple and easy ICP/IP protocol stack in Design of System Software on the basis of realizing the fire-fighting remote data transmission, adopted the storage transmit mechanism when data are handled, and guarantees the reliable and stable transmission of fire-fighting data; The power supply plan of system adopts main electricity preferential, suspend charging, active and standby electric automatic switching method, has guaranteed the reliability of system's power supply; Adopt wire transmission to adopt pattern in the past in the transmission plan, and wireless transmission has adopted the GPRS pattern, can adapt to different site environments.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, the embedded multichannel fire-fighting of technical grade of the present invention remote monitoring transmission equipment, comprise cabinet 4, the mainboard 2 in the cabinet 4 and the control panel 3 on cabinet 4 surfaces, also comprise power panel 1, power panel 1 is connected with mainboard 2, for mainboard 2 provides power supply, mainboard 2 comprises master chip and extends out the Flash storage chip, master chip adopts CORTEX-M3 to examine 8962 chips, described control panel 3 is provided with independent button and LED display lamp, independent button is connected with mainboard 2 with the LED display lamp, also be connected with the RS232 interface on the mainboard 2, jtag interface, RS485 interface and Ethernet interface, described power panel 1 comprise active/standby electro-detection control and the switching device shifter that main electricity/power backup power supply and the main electricity of control/power backup power supply switch, and also connect an alarming horn on the described mainboard 2.
Operation principle:
1. power management part: open transmission equipment master electricity power supply, system starts working, and control panel 3 shows the work at present states, and mainboard 2 adopts 24V input power supply; Unusual or the brownout of power backup shows the power backup fault, and power backup voltage is lower than the main electricity of 18V system control and is the power backup charging, and charging is higher than 27V and disconnects and charging; System detects automatically and switch to the power backup duty before system closing during main electric power down.
2. local state shows and hop, the duty of transmission equipment real time monitoring oneself:
2.1 this machine fault upload, system detects this machine faults such as equipment master electric fault, power backup fault with the timely active upload of information, and adopts acousto-optic hint, adopts 5 retransmission mechanism of shaking hands information that make correctly to upload;
2.2 wireline inspection, system detect in real time between own and the slave computer control the communication line state and with Surveillance center's line status, the glittering prompting of corresponding lamp when obtaining line fault, and the sound prompting of sounding a buzzer, wireline inspection to state in time be transferred to Surveillance center;
2.3 in-local shows and uploads, operating personnel press manual warning or other buttons will produce packet, the mode that information adopts storage to retransmit is uploaded Surveillance center, behaviour presses when button, the lamp flicker of button next door, obtain becoming Chang Liang after the answer confirmation of Surveillance center, have artificial affirmation or 60S back light to extinguish;
2.4 the storage of the information of controller and transmission, the how tame controller information of transmission equipment compatibility receives and uploads, transmission equipment receives by information such as the fire alarm of RS232 transmission, supervision, shielding, fault, actions, to receive the corresponding information lamp of information glittering when transmission equipment, and data are transferred to Surveillance center by GPRS or Ethernet, the information lamp becomes Chang Liang after obtaining the answer data of Surveillance center, obtains alert elimination button and confirms that back information lamp point goes out.
