Abstract
The utility model relates to a temperature monitoring system based on zigbee, which is a terminal node formed by a zigbee terminal module and a temperature sensor module, wherein the terminal node is located at a testing position and the terminal node is used for reading a signal of the temperature sensor module; the terminal node and a zigbee coordinator are in wireless communication; and a computer and the zigbee coordinator are in communication connection by utilizing a USB (Universal Serial Bus). The temperature sensor module disclosed by the system can monitor a temperature in a network covering range of the zigbee coordinator in an online manner, and also can leave from the network covering range of the zigbee coordinator to collect the temperature; and after the temperature sensor module enters the network covering range of the zigbee coordinator, the temperature sensor module can upload temperature data stored in a FLASH chip into the zigbee coordinator in a wireless manner, and further upload the data to the computer. With the adoption of two working modes, the temperature can be more flexibly monitored and sampled and the temperature monitoring system can be applied to more fields to finish a monitoring task.
Description
Technical field
The utility model relates to a kind of measuring technique, particularly a kind of temperature monitoring system based on zigbee.
Background technology
Zigbee be a kind of emerging closely, low complex degree, low-power consumption, radio network technique cheaply, be mainly used in during short-range wireless transmission uses.It is fit to be applied to aspects such as industry, health care according to the IEEE802.15.4 standard.Monitoring temperature mode in the market all is to adopt wired mode basically, promptly uses the lead ways of connecting to come the transmission measurement data.Because of adopting the wired connection mode, the selection meeting of sampling node is limited greatly because of factors such as distance, height, thereby brings very big inconvenience for the installation and maintenance of sampling node.And for the product of some temperature sensitivities, each links such as its production, transportation, storage all must be carried out monitoring temperature, guarantee product quality.In each link of transportation, sale, these products tend to the variation of occurrence positions, and needing one can come product temperature is monitored with the wireless temperature sensor-based system that product moves.
Existing scientific and technical literature also discloses the solution of some wireless temperature monitoring; What adopt is simple wireless data transmission, receive mode more, and this makes comparatively complicacy of the construction of total system and newly built construction more, poor expandability; Then networking is convenient to adopt zigbee, and extensibility is strong.
Summary of the invention
The utility model is the problem loaded down with trivial details to wiring in present wired controlling schemes, that maintenance load is big; A kind of temperature monitoring system based on zigbee has been proposed; Employing is based on the radio communication of zigbee agreement; Make that system power dissipation is low, cost performance is high, networking is convenient, installation and maintenance are simple, extensibility is strong, also more flexible to the monitoring of temperature.Can break away from the restriction on the monitor procedure space-time, can apply to more conditions and accomplish the monitoring task.
The technical scheme of the utility model is: a kind of temperature monitoring system based on zigbee; The terminal node that constitutes by zigbee terminal module and temperature sensor module; Terminal node is positioned at test position, and its inside comprises clock chip, FLASH chip, temperature sensor, antenna, master chip CPU, power supply, terminal node reading temperature sensor signal; Adopt usb communication to be connected between terminal node and the wireless telecommunications of zigbee telegon, computing machine and zigbee telegon.
Master chip CPU control collecting temperature sensor signal is sent in the FLASH chip and is stored in the said terminal node, and master chip CPU calls in the FLASH chip data and sends into the zigbee telegon through antenna.
The beneficial effect of the utility model is: the utility model is based on the temperature monitoring system of zigbee; The temperature sensor module of this system can be in the network coverage of zigbee telegon online monitoring temperature; The network coverage that also can leave the zigbee telegon removes collecting temperature; By the time get into after the network coverage of zigbee telegon; Temperature sensor module can be uploaded the zigbee telegon to the temperature data that is stored in the FLASH chip through wireless mode, and then is uploaded to computing machine.The upper computer software of computing machine is realized the temperature data of gathering is shown, stores.Adopt two kinds of mode of operations, more flexible to the temperature monitoring sampling, also can apply to more conditions and accomplish the monitoring task.
Description of drawings
Fig. 1 is the fundamental diagram of the utility model based on the temperature monitoring system of zigbee;
The terminal node figure that Fig. 2 is constituted for the utility model zigbee terminal module and temperature sensor.
Embodiment
As shown in Figure 1, a kind of temperature monitoring system based on zigbee comprises computing machine 16, zigbee telegon 14, zigbee terminal module 4,8,12, temperature sensor module 2,6,10.Zigbee telegon 14 is connected electrically on the computing machine 16, and zigbee terminal module 4,8,12 connects temperature sensor module 2,6,10 respectively.And, adopt usb communication to be connected between computing machine 16 and the zigbee telegon 14.
As shown in Figure 2, by the terminal node that zigbee terminal module 4 and temperature sensor module 2 constitute, its inside comprises clock chip 18, FLASH chip 20, temperature sensor 22, antenna 24, master chip CPU26, power supply 28.
There are two kinds of monitoring patterns in system: first on-line temperature monitoring mode of operation, the terminal node that promptly constitutes when temperature sensor module 2,6,10 and zigbee terminal module 4,8,12 are in zigbee telegon 14 network coverages the time.It two is off-line temperature monitoring patterns, and the terminal node that promptly constitutes when temperature sensor module 2,6,10 and zigbee terminal module 4,8,12 is away from the zigbee telegon, is in the network coverage of zigbee telegon outward the time.
A kind of concrete course of work of the temperature monitoring system based on zigbee is following: when product be in produce and temporary stored procedure in the time, system is in online monitoring temperature mode of operation.Begin from the needs temperature monitoring, whole monitoring system starts, and zigbee telegon 14 is responsible for the establishment of network, makes numerous terminal nodes and zigbee telegon 14 constitute a zigbee network.System is in service at on-line temperature monitoring; According to user's request of gathering or system's setting; Master chip CPU26 in the terminal node only carries out read-write operation to temperature sensor 22; And the temperature data that is read is sent to zigbee telegon 14 through antenna 24, zigbee telegon 14 is passed to computing machine 16 with the data sink coalescence through USB and is done further processing and be shown to the user.When if the user does not have the data acquisition request, terminal node only carries out the scan channel of low-power consumption, to guarantee the operation of zigbee network.When product is in the transportation, system is in off-line temperature monitoring mode of operation.According to the acquisition time of initial setting at interval, the time signal correspondence of the temperature data that will gather from temperature sensor 22 of terminal node and clock chip 18 temporarily is stored in the FLASH chip 20.When product arrival destination, in the storage, system is in online monitoring temperature mode of operation again.Terminal node adds in the network of zigbee telegon 14 compositions again, and at this moment the user can pass through computing machine 16, and the temperature and time data that are stored in the terminal node FLASH chip 20 are uploaded to Computer Database one by one.Thereby accomplished temperature monitoring, guaranteed product quality each links such as production, transportation, storages.
