Fig. 2 is a micronic dust unit detection and control terminal structured flowchart.
Among the figure: 1, host node, 2, the Zigbee unit, 3, the Internet of Things network, 4, data collection station, 5, the micronic dust unit, 6, survey sensor, 7, power supply unit.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, gate perception observing and controlling intelligent node is mainly by two most of compositions: host node 1 and data collection station 4.Host node 1 all inserts in the Internet of Things network 3 of early gate through Zigbee unit 2 with micronic dust unit 4.
Present embodiment host node main body is the SCM system that connects the Zigbee radio communication unit, and The software adopted wherein is embedded, adapts to the situation that the micronic dust unit freely increases or reduces with perception.The single-chip microcomputer of host node adopts the 89C58 of STC, possesses 32K program storage, 1K RAM and 16KEEPROM, and chip integration becomes house dog, supports online programming, satisfies the functional requirement of host node fully.Software section adopts the embedded programming method, in the work period, accomplishes scanning to the micronic dust unit in this gate scope automatically, confirms, includes in the control tabulation.Automatically the entry and exit of perception micronic dust.
Host node is the core in the utility model, and it mainly accomplishes three functions: 1, through Internet of Things network and other node and Central Control Room contact, the monitoring system state oneself is independent operating or includes in system's team control determining; 2, the data that oneself collected send to Central Control Room through Internet of Things, receive and accomplish control command that Central Control Room sends, order and other system works are set, debug command such as self check; 3, perception terrain micronic dust exists, and carries out the micronic dust configuration automatically, detects micronic dust data measured, duty, Realtime Alerts processing etc.
Host node is installed in the terrain switch board, and it is supplied power by the alternating current 220V in the terrain switch board through the power rectifier treatment and supplied.Host node also supports common industrial fieldbus such as RS485/CAN directly to connect with Central Control Room with wired mode, to form bus redundancy with the Internet of Things network, backups each other.The data acquisition of host node is all carried out through Internet of Things, does not therefore connect input, but possess 7 relay outputs is arranged; These relays can insert in the gate control secondary circuit; With ascending, descending, the shut-down operation of realization gate, but the electricity operating breaker in the while may command secondary control loop, with in case of emergency; But disconnected power down operating breaker, the protection gate.
Communication between the host node of host node and other gate and the Central Control Room node; It is system-level principal goods networking network; The existence of each node through other node of perception comes total duty of non-decision-making system, and when can't find the existing of other point, just being provided with own is the independent operating state.In addition, if a node failure, can pass through a brief fault communication frame, issue other node and Central Control Room node, in time report to the police and processing to impel Central Control Room.In the duty, if a node failure, also can notify the micronic dust in self compass of competency, be set to the host node that closes on to impel these host nodes, the host node that closes on also can take over the work of these micronic dusts by certain rule.Like this, when indivedual terrain host nodes damage, still can guarantee the normal operation of system.
As shown in Figure 2, data acquisition middle-end 4 comprises micronic dust unit 5, and micronic dust unit 5 is connected to Zigbee radio communication unit and survey sensor 6, and by power supply unit 7 power supplies.Micronic dust unit 5 main bodys adopt ultra low-power microcontroller.The Zigbee unit be responsible for and host node between the foundation and the communication process of Internet of Things network.Power supply unit 7 is responsible for supplying power to the micronic dust unit.The access of power supply is mainly confirmed according to the type of survey sensor.To not needing big driving voltage and lower-powered survey sensor, perhaps do not need the micronic dust unit of survey sensor, can adopt powered battery.Gather the micronic dust of voltage/current data such as the load sensor that adopts Huygens's resistance bridge mode or through the voltage/current mutual inductor, can directly use powered battery.Because under off working state, can the entering dormant state be set by host node, and single-chip microcomputer employing low-power consumption low-voltage version, through test, a joint 9V square battery can make the work of this type micronic dust more than 1.5 years.For big driving voltage of need or the bigger sensor of power, then need insert the 220V AC power, behind voltage transformation, obtain suitable low-voltage DC.As adopt the jaw opening sensor of contact scrambler, because of power is required bigger, be not suitable for adopting powered battery.
Survey sensor is then selected according to installation site, micronic dust unit, and the micronic dust unit itself is general.When being installed in the aperture position and being used for aperture measurement, the corresponding jaw opening sensor of survey sensor then; When being installed in the fuel temperature measurement position, survey sensor corresponding temperature sensor then.Single-chip microcomputer is responsible for the pick-up transducers data, and through the host node contact of Internet of Things and this gate, reported data also receives the information that is provided with that host node is sent.Simultaneously,, the terrain data are judged, run in emergency circumstances, promptly directly send the emergent management code, and report and submit host node to the predetermined micronic dust unit that has topworks by promptly establishing rules then.When running into the host node fault, perception periphery host node, and the request of sending is automatically taken over and is ordered.Realize automatic perception observing and controlling.
Be to realize overall monitor to gate, be provided with altogether gatage, loading, voltage/current, on/sensors such as lower limit; Under the situation to hydraulic headstock gear, also be provided with, all can realize overall monitor parameters such as oil pressure, oil temperature, twin-tub corrections.And owing to adopted the scheme of deploying to ensure effective monitoring and control of illegal activities of the micronic dust of little power consumption, can be in the overall monitor that guarantees to realize under the basic consistent situation of budget gate with traditional product.
