Send data, cause bus short circuit, thus damage the phenomenon of some node；3, communication distance is restricted.And existing machine
Safety and the promptness of the process of room supervising device problem too high to carbonomonoxide concentration are the most inadequate.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that a kind of based on CAN communication bus machine room observing and controlling one
Carbonoxide monitoring device, based on CAN communication bus and utilize CAN communication mechanism carbon monoxide transducer is gathered data to be transferred to
Main frame, and automatically process.
This utility model is achieved in that carbon monoxide monitoring system based on CAN communication bus machine room observing and controlling, mainly
Including carbon monoxide transducer, CAN communication bus, main frame, exhaust equipment, power module, cable-network transmission module, clock together
Step module and data memory module, it is characterised in that: the some carbon monoxide transducers laid in machine room are all connected to same CAN
Communication bus, CAN communication bus is connected to main frame, and main frame gathers data to all of carbon monoxide transducer and is analyzed,
Main frame connects exhaust equipment master controller and automatically controlled window controller the most respectively, and exhaust equipment master controller connects in machine room respectively
Exhaust equipment, automatically controlled window controller connects automatically controlled window respectively.
Described main frame is also connected with wireless communication module, by wireless communication module to wireless communication terminal set in advance
Send carbon monoxide monitoring warning information, it is simple to the technical staff of wireless communication terminal side understands alarm situation in time, and makes
Process in time, solve carbon monoxide monitoring abnormal problem.
Described automatically controlled window is that relative position is arranged in machine room, it is ensured that preferably ventilation effect.
Described carbon monoxide transducer and the corresponding relation of exhaust equipment are one to one, or are many-one.
Described power module comprises mains power supply and UPS electric supply installation.
Described main frame uses model to be the single-chip microcomputer of SPCE061A.
Described carbon monoxide transducer uses model to be the sensor of GTH1000.
The corresponding relation of carbon monoxide transducer and exhaust equipment, carbon monoxide transducer collection is pre-set on main frame
During carbon monoxide Monitoring Data exception, main frame sends instruction to exhaust equipment master controller, exhaust equipment master controller control
Opening corresponding exhaust equipment startup work, meanwhile, automatically controlled window controller controls automatically controlled window and opens ventilation.
CAN communication is a kind of serial communication network supporting distributed controll or control in real time, compared with general communication mechanism
Relatively have the advantage that
1, the data communication between each node of network is real-time, does not has master-slave.Different nodes can be simultaneously received
Identical data is avoided needing the mode meeting main website poll to carry out information exchange as RS485 communication mechanism.
2, increase the safety of equipment room communication, prevent as RS485 when system is problematic, the while that multinode occurring
Send data, cause bus short circuit, thus damage the phenomenon of some node.Because CAN node has in the case of mistake is serious
It is automatically switched off output function, so that the operation of other nodes is unaffected in bus, thus ensures not have in a network
Because respective nodes goes wrong so that bus is in " deadlock " state.And the perfect communications protocol that CAN has can be by CAN
Controller chip and interface chip thereof realize, thus are substantially reduced system development difficulty, shorten the construction cycle, and these are only
Electrically the RS485 of agreement is incomparable.
3, communication distance farthest up to 10km(speed less than 5kps) communication distance less than 40m(speed up to 1mbps), because of
Employing two wire serial communicates, and error detecing capability is strong, can work in strong noise interference environment, and because using short frame structure, transmission
Speed is fast, and can hang node in theory does not has the upper limit.
The beneficial effects of the utility model are: 1, this carbon monoxide monitoring system carries out data biography based on CAN communication bus
Defeated, compare the communication buses such as common RS232 communication bus, RS485, it has, and data communication is real-time, motility good, peace
The features such as Quan Xinggao and communication distance are remote；2, exhaust equipment and automatically controlled window start automatically, reduce human error and labor workload；
3, main frame sends carbon monoxide monitoring warning information from trend wireless communication terminal, it is simple to the problem of carbon monoxide monitoring exception obtains
To processing in time, it is ensured that calculator room equipment stable operation.
