Description
Technical field
This utility model relates to electronic measuring device field, in particular it relates to a kind of wireless temperature transmitter based on wifi communication.
Background technology
Temperature transmitter is a kind of conventional temperature testing equipment, and its function is that the temperature signal recorded by temperature probe is converted into the signal of telecommunication and shows on display module.Existing radio temperature sensor, it includes temperature collecting device, signal conditioning circuit and the processor being sequentially connected with, existing radio temperature sensor its power only with monocell, sky sun is used can battery to be charged, there is a lot of problem in it, if its illumination is not enough, the energy content of battery is not enough and has little time to change battery, the situation that temperature transmitter cannot work will occur.
Utility model content
This utility model provides a kind of wireless temperature transmitter based on wifi communication to solve above-mentioned technical problem.
The technical scheme in the invention for solving the above technical problem is:
nullWireless temperature transmitter based on wifi communication，Including housing、The display module being arranged on housing and the temperature transmitter being arranged in housing，Described temperature transmitter includes temperature collect module、Signal conditioning circuit and processor，Connect on described processor and have information transfer module，Described display module connects on a processor，It is provided with photovoltaic battery panel on described housing，Described photovoltaic battery panel is connected with accumulator by management of charging and discharging circuit，Described information transfer module is wifi module，Described temperature transmitter also includes isolating circuit，Described temperature collect module、Signal conditioning circuit、Isolation circuit and processor are sequentially connected with，Described accumulator has two and two electric power storages are connected with processor by power change-over switch，Described accumulator is connected in electric power detection module，Described electric power detection module connects on a processor.This utility model improves on the basis of existing technology, one, isolation circuit is set between processor and signal conditioning circuit, utilize the characteristic of isolation circuit signal one-way transmission, make signal be only capable of from temperature collect module and be sent to processor end, avoid interference the signal impact on temperature collect module, improve the reliability of data acquisition；Its two, two accumulator are set, make two accumulator be mutually redundant, it is to avoid single battery do not have electricity situation；Its three, use wifi module to realize the Wireless transceiver of signal.Its operation principle is same as the prior art, is now only illustrated battery power pack principle.Solar energy is changed and charges accumulator by photovoltaic battery panel, the discharge and recharge of accumulator is managed by management of charging and discharging circuit, avoid accumulator super-charge or excessively put, the other charge condition to two accumulator of electric power detection mode division detects and sends detected status information to processor, power change-over switch is controlled by processor according to this information, selects the storage battery power supply of suitable electricity.
As preferably, described isolation circuit is optical coupling isolation circuit.Optical coupling isolation circuit utilizes the unipolarity of photo-coupler to limit signal transmission direction, and its circuit structure is simple, and be those skilled in the art all known to technology, it is easy to make.
As preferably, for the ease of the processor control to power change-over switch, described power change-over switch is electrical switch.
As preferably, described photovoltaic battery panel is arranged on the outer wall of housing.
Further, in order to strengthen the photovoltaic battery panel absorbability to illumination, the outer wall of described housing is provided with photovoltaic battery panel.
To sum up, the beneficial effects of the utility model are:
1, this utility model arranges isolation circuit between processor and signal conditioning circuit, utilize the characteristic of isolation circuit signal one-way transmission, make signal be only capable of from temperature collect module and be sent to processor end, it is to avoid the interference signal impact on temperature collect module, improve the reliability of data acquisition.
2, this utility model arranges two accumulator, makes two accumulator be mutually redundant, it is to avoid single battery does not has the situation of electricity.
