Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
With reference to shown in Figure 1, the utility model diesel-driven generator fuel consume monitoring system, comprise some diesel-driven generators, diesel-driven generator is connected with flow sensor, also comprise fuel consumption meter, fuel consumption meter links to each other with flow sensor, the data on flows that fuel consumption meter acquisition stream quantity sensor detects, and fuel consumption meter links to each other with host computer by Zigbee.Shown in Figure 1ly be provided with three diesel-driven generators, can certainly be independent one, Liang Tai, four or more, the utility model is not limited.
Diesel-driven generator is connected with flow sensor in the utility model, and these flow sensors can detect the diesel oil amount that diesel-driven generator consumes.In addition, in order further to improve measuring accuracy, fuel consume monitoring system in the utility model can also comprise fuel tank, fuel tank is connected with oil inlet pipe and flowline, flowline is connected with the oiler of some diesel-driven generators by fuel delivery line, and the oiler of oil inlet pipe, flowline, diesel-driven generator is connected with flow sensor.The advantage of She Zhiing is that it does not need to dismantle oil feed line as prior art like this, so detection method is simple, and cost is lower.As shown in Figure 1, be equipped with the flow sensor except the oiler at three diesel-driven generators like this, be provided with flow sensor at oil inlet pipe and the flowline of fuel tank.The oil inlet pipe of fuel tank and the flow sensor of flowline can be used for the detection to the each volume read-out of fuel tank and oil tank fuel total reduction.So just can increase the detection parameter, compare by the flow sensor that is connected with diesel-driven generator, can further improve measuring accuracy.
The utility model is the limited flow type of sensor not, and existing flow sensor mainly can be divided into following a few class by structural principle: positive displacement, vane type, differential pressure type, impulse type, momentum-type, ultrasonic sensor etc.Most of sensors can both be continuously, accumulative total is measured, but flow range and the flow error measured have nothing in common with each other, and the environment that is suitable for is also different with condition.
Commonly used is speed mode flow sensor and volumetric flow sensor now.To measure the flow sensor that rate of flow of fluid obtains fluid flow, be called the speed mode flow sensor.Its kind is a lot, and development in recent years is also very rapid, relatively typical case and commonly used turbine flow transducer, vortex flow sensors, electromagnetic flow transducer, ultrasonic flow sensor and thermal flow rate sensor etc. are arranged.
Utilize the mechanical measurement element that fluid continuously is divided into single known volume part, repeatedly be full of one by one and the number of times that discharges this volume segment fluid flow is measured the flow sensor of fluid volume total amount according to measuring chamber, be called volumetric flow sensor.
As preferably, the utility model can adopt turbine flow transducer.The principle of turbine flow transducer is when the fluid sensor housing of flowing through, because the blade of impeller has certain angle with the flow direction, the impulse force of fluid makes the blade moment that rotates, the blade rotation of overcome friction square and fluid resistance, stabilization of speed after equalising torque.Under certain condition, rotating speed is directly proportional with flow velocity, because the magnetic conductivity of blade, it is in the signal supervisory instrument magnetic field of (being made up of permanent-magnet steel and coil), the blade cuts magnetic induction line of rotation, the periodic magnetic flux that changes coil, and making the coil two ends induce electric impulse signal, this signal is formed with the continuous rectangular wave pulse with certain amplitude through the amplification shaping of amplifier, but final teletransmission demonstrates instantaneous delivery or the total amount of fluid to Displaying Meter.
The preferred turbine flow of the utility model is suitable for measuring the low liquid of viscosity (as oil) very much, have that accuracy of measurement height, range ability are wide, good linearity, can bear the big advantage of working pressure, measuring accuracy reaches as high as, and is the highest class sensor of precision in the like product.
Further, the characteristic of considering turbine flow transducer directly is subjected to the influence of fluid flow state, and the forward and backward straight length that certain-length is installed respectively of place turbine flow transducer is in order to stablize the fuel oil fluidised form.
The utility model is based on the Zigbee technology.Zigbee be a kind of low rate, low-power consumption, closely with the communication technology of self-organization, it is low in energy consumption, cost is low, time delay is short, network capacity is big, data transmission is reliable, have and exempt to permit wireless communication frequency band, transmission as safe as a house.Based on above characteristics, the Zigbee network becomes the first-selection of wireless sensor network, and it is suitable for making up sensor network under industrial environment very much.
The equipment of Zigbee can be divided into two classes by function: have complete function full-function device (Full Function Device, FFD) and have only partial function the simplification function device (Reduce Function Device, RFD).Full-function device not only can be communicated by letter with simplifying function device or other full-function devices, and can control topology of networks.Simplify function device and can only can not control network topology structure with full-function device communication.The application of simplifying function device is simple, is easy to realize, does not need to send lot of data simultaneously, and once can only one of association simplify function device, therefore, only needs to use less resource and storage space.
In the equipment of in the LR-WPAN network, supporting, can be divided into three kinds of device types again by the status in network: network coordinator, router and terminal device.
The Zigbee telegon: be in the top layer of network structure, telegon is always in running order, must supply with stable, power supply reliably to its.It also formulates networking rule except some functions that can finish router, select suitable channel, starts network, and the Zigbee telegon must be FFD, and has only a Zigbee telegon in a Zigbee network.
Router: be in the intermediate level of network, must possess storage, transfer capability and the route discovery ability of data, also must support the connection of its subset and the maintenance of routing table, it must be FFD.
Terminal device: its 26S Proteasome Structure and Function is simple, often just transmits and receive data simply, does not handle functions such as network management, and the most of the time is in sleep state, saves energy so farthest, and extending battery life, it can be FFD or RFD.
The utility model has adopted Zigbee telegon and Zigbee router.In the utility model, fuel consumption meter connects the Zigbee router, and host computer connects the Zigbee telegon.Host computer can be PC, also can select other suitable types.
Because the connectivity port difference between fuel consumption meter, Zigbee router, Zigbee telegon and the host computer can adopt serial converter to connect said modules.Serial converter commonly used is that RS-232 changes the RS-485 converter.Can certainly select the serial converter of other types.
Zigbee device in the utility model need use the Zigbee radio transmitting and receiving chip.As preferably, the utility model can select for use the XBEE-PRO of U.S. DIGI company as radio transmitting and receiving chip.This chip meets the IEEE802.15.4 standard, is operated in the 2.4GHz frequency range, is that a kind of volume of comparative maturity is little, low in energy consumption, long transmission distance, is fit to set up the wireless communication module of power consumption wireless sensor network.
