Abstract
The utility model provides a wireless sensor comprising a main sensor circuit, a wake-up circuit and a magnetic rod, wherein the main sensor circuit includes a CPU, the wake-up circuit is connected with the CPU and is internally provided with a magnetically-controlled switch, and the magnetic rod is in induction connection with the magnetically-controlled switch. As the magnetically-controlled switch is packaged inside the shell of the wireless sensor, direct invasion of high dust and high humidity is avoided, and the reliability of a system is improved; wake-up is triggered by a non-contact method, namely through approaching of the magnetic rod, direct key pressing is not needed, the influence of the key size to operation is avoided, and convenience is provided for the use of the wireless sensor.
Description
Technical field
The utility model is specifically related to a kind of wireless senser.
Background technology
Wireless senser adopts the mode of wireless telecommunications that the physical quantity of measurement is transferred to distal displayed platform or portable manual operator, and a lot of wireless sensers show with this locality simultaneously.For battery powered wireless senser, in order to guarantee the power-on time of battery, not measuring, do not transmit, while not showing, sensor, in dormant state, needs regularly or manually wake up to enter duty, to be measured, to show and to check meter.Timing wake-up is waken up by the timer clock be preset in wireless senser, for very long sensor measuring period, when needs are measured in real time in the middle of 2 wakeup times, need to manually wake up.
Existing artificial awakening mode is all to adopt manual key mode at present, and because the environment that industrial wireless sensor is installed is generally all poor, button is exposed in the environment of high dust high humidity, often lost efficacy, and the industrial wireless sensor volume is generally less, button is also corresponding little, thereby operation inconvenience.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of wireless senser, adopts the approaching cordless of bar magnet to excite and wakes up, has facilitated use.
The utility model solves the problems of the technologies described above by the following technical programs: a kind of wireless senser, comprise a sensor main circuit, a wake-up circuit and a bar magnet, and described sensor main circuit comprises a CPU; Described wake-up circuit is connected with described CPU, and has a magnetic switch in this wake-up circuit; Described bar magnet is connected with magnetic switch magnetic induction.
Preferably, the model of described magnetic switch is GPS-14A.
The beneficial effects of the utility model are: because magnetic switch is encapsulated in the wireless senser enclosure interior, avoided the direct invasion and attack of high dust high humidity, improved system reliability; Adopt the approaching cordless of bar magnet to excite and wake up, without direct button, avoided the impact of button size on operation, greatly facilitate use.
The accompanying drawing explanation
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
The structural representation that Fig. 1 is a kind of wireless senser of the utility model.
Embodiment
Refer to Fig. 1, a kind of wireless senser, comprise a sensor main circuit, a wake-up circuit and a bar magnet, and described sensor main circuit comprises a CPU; Described wake-up circuit is connected with described CPU, and has a magnetic switch in this wake-up circuit; Described bar magnet is connected with magnetic switch magnetic induction.
Described sensor main circuit:, demonstration aobvious for surveying and transmitting physical amount.
The model of described magnetic switch is GPS-14A.
Described wake-up circuit: for regularly or take orders, wake the sensor main circuit up, to save the energy.
Described magnetic switch: for responding to strong magnetic signal, produce wake-up signal, to activate wake-up circuit and sensor main circuit.
The utility model is encapsulated in magnetic switch in the wireless senser housing, in order to substitute the conventional manual button, becomes wake-up switch; When operating personnel hold bar magnet and approach wireless senser, the magnetic switch closure that is excited, produce wake-up signal, wakes sensor up and measured, show and transmit data.
