Description
Technical field
The utility model belongs to wireless network application technology apparatus field, especially relates to a kind of teaching experiment system of configurable sensor.
Background technology
(Wireless Sensor Networks WSN) is a kind of emerging network technology that combines technology such as microelectromechanical systems, SOC (system on a chip), radio communication, low-cost sensor to wireless sensor network.The ad hoc wireless communication network of the oriented mission that it normally is made up of the node with information obtaining ability of a large amount of cheapnesss, the important component part of front end sensing layer as " Internet of Things " research, have very wide application prospect, and caused the extensive concern of academia and industry member.Thereby produced huge demand for talent in the wireless sensor network direction.This demand for talent has proposed new demand to colleges and universities in the experiment porch construction of wireless sensor network again.Experiment porch is not only the platform of student's curriculum experiment, and is the research platform of being engaged in radio sensing network.Yet existing experiment porch can not satisfy this demand, is mainly reflected in:
(1) because the used node of experiment is larger, when causing the student to do experiment, expended a large amount of time to repeat to cause conventional efficient low on the loaded down with trivial details link.For example: existing wireless sensor network node generally all uses hardware emulator that node is programmed, and obvious this method relates to artificial plug and program burn writing operation repeatedly inevitably, and this is very consuming time and loaded down with trivial details.
(2) lack effective experiment test method.Traditional method of obtaining test data of experiment is that the experimental data that node reports needs is wirelessly transmitted to the sink node, reports PC by the sink node by serial ports or port and does further processing.This experimental data collection mode is not suitable for the experiment that a large amount of experimental datas are arranged, for example complicated experiment such as time synchronized, routing algorithm.If great deal of experiment data adopts wireless transmission, not only can have an immense impact on to experimental result, and may make whole network paralyse, what influence was tested normally carries out.
(3) the current experiments system does not have hardware reprovision ability.The current experiments system generally only supports the experimental teaching of several fixation of sensor, for example humiture, CO2 concentration etc., although the driving of these sensors exploitation is similar, but since experimental system can not reprovision, make that when facing new sensor the student need be at the driver of the basis of hardware layer exploitation node.But concerning elementary student, they lack the expansion that enough development abilities are finished experiment.
(4) the current experiments system can not onlinely use, and the student generally can only under lab use equipment, and resource utilization is low.
The utility model content
In order to remedy the bothersome effort of above-mentioned test platform, use inconvenience, the defective that utilization factor is low the utility model proposes a kind of teaching experiment system of configurable sensor.
The technical scheme that realizes above-mentioned beneficial effect is, a kind of teaching experiment system of configurable sensor, described system comprises experiment porch, the sensor interface that is connected with experiment porch respectively and intelligent gateway, experiment porch is built-in with storage module and processing module, processing module is connected with storage module with sensor interface respectively, and intelligent gateway connects together the formation topological network with a plurality of experiment porchs.In the technical program, adopt intelligent gateway that experiment porch is connected together, storage module between a plurality of experiment porchs can be shared, sensor information can share to whole topological network after being stored into some storage modules, simplified stored routine, avoid the loaded down with trivial details step when sensor uses simultaneously, improved service efficiency.
Experiment porch also is connected with networking component, and networking component connects together experiment porch with extraneous internet.In the technical program, adopt networking component that experiment porch is arrived with network connection, the user operates experiment porch by network, improves the range of application of experiment porch.
Described experiment porch also comprises instrument module and display module, and the instrument module is connected with processing module respectively with display module.In this technical program, the kind of the compatible multiple sensors of instrument module, difference according to sensor shows different results respectively, and the sensor type that display module then will be tested now and working sensor state and platform real-time information show more intuitively.
Described instrument module adopts the liquid crystal instrument dish.Adopt the liquid crystal instrument plate, have wide range of applications than original machinery instrument dish, the result shows more accurate.
Described intelligent gateway inside is provided with the zigbee communication module, and a plurality of experiment porchs connect together by the zigbee communication module.Adopt the mode of zigbee communications protocol, a plurality of gateways are connected to each other, and the network transmission is stable, consistent maturation.
The utility model is by having stored program in advance at experiment porch, do not need refresh routine in use, node can be to the present sensor type that connects of own this node of gateway requests when just powering on, gateway has been deposited the sensor information of this node, so after receiving the request of node, can tell this node the sensor information of this node, node can call corresponding routine interface and come this sensor of driven; In the utility model, the sensor program online updating that experiment porch stores is by using software just can carry out online updating to the program on the node, need not on-the-spot the renewal, and the user can finish operation to experiment porch by network, improve service efficiency; Simultaneously, the utility model need not the experimenter more separately to sensor platform burning sensor information, has avoided repeating the loaded down with trivial details step of original sensor burning; The utility model is formed topological network by gateway, has avoided original transmitting step, has improved the exchange capacity of communication efficiency and data, is convenient to large-scale experiment.
