Description
The present invention relates to a kind of paging receiver, more particularly, relate to a kind of paging receiver of measuring and showing the received signal intensity indication (hereinafter referred to as RSSI) of received signal.
The present invention shows that the paging receiver of received signal intensity indication proposes according to korean patent application 15224/1995, also includes this patent application, for your guidance here.
Fig. 1 is the block diagram of the general structure of explanation paging receiver.Usually, structure paging receiver as shown in Figure 1 all has the function of external call notification being given the user.Among Fig. 1,100 pairs of radiofrequency signals of receiving by antenna of radio-frequency (RF) Receiving Device are carried out demodulation, and the signal waveform with demodulation is transformed into numerical data then, and the numerical data with waveform shaping is added on the controller 102 again.Then, 102 pairs of radio-frequency (RF) Receiving Device of controller 100 are decoded for the data of coming, thereby detect preamble and word is synchronous.During the suitable address date of retrieval paging receiver itself, controller 102 drives multiple warning device (not shown) according to the working method of keying in device 104 settings, or at display 106 information of receiving is shown.At this moment, controller 102 has and is used for storing the suitable address date and the memory of frame data.Controller 102 is used for retrieving the data of corresponding paging receiver itself from the data of receiving, thereby the information of receiving is temporarily stored.
When being in outside the constant scope in operation area, normally can not bring into play above-mentioned beeper the radio-paging effect.Therefore, controller 102 is notified from a phone call professional possibility from radio-frequency (RF) Receiving Device 100 for the Data Detection of coming, thereby notifies its residing zone of user corresponding to carrying out the operation area or corresponding to carrying out the operation area by display 106.
On the other hand, can carry out in the operation area even paging receiver is in, the RSSI level of received signal is remained unchanged, the RSSI level of each relevant position is different.When having barrier or radio wave to end on every side (for example at basement), the RSSI level will be much lower, in the worst case, even can not notify from a phone call in can carrying out the zone of operation.
General paging receiver does not possess RSSI level determination function.Therefore, in the field test of product development, always be to set reference level with the RSSI sensing equipment, very inconvenient.In addition, do not know the RSSI level of present position at that time, thereby use paging receiver to have any problem owing to the user only knows whether to notify from a phone call.
Therefore, the purpose of this invention is to provide a kind of paging receiver that can detect and show received signal intensity indication (RSSI) level of received signal.
For achieving the above object, paging receiver with demonstration received signal intensity deixis provided by the present invention comprises: radio-frequency (RF) Receiving Device, in order to detect the voltage level of the radiofrequency signal of receiving by antenna, thereby the voltage level that output detects, radio frequency voltage of signals level is carried out demodulation afterwards the voltage level waveform transformation of demodulation is become numerical data, thus the voltage level of output waveform shaping; A/D converter is in order to produce the numerical data of data value corresponding to the detected voltage level values of radio-frequency (RF) Receiving Device; Key in device, for the display mode of setting the indication of received signal intensity; A controller is in order to detect the level of received signal intensity indication with the output of A/D converter according to the received signal intensity indicated number mode of keying in the device setting; With a display, in order under the control of controller, to show the level of detected received signal intensity indication.
Be the detailed description of the present invention with reference to accompanying drawing below, same numbering is represented same or similar elements in the accompanying drawing.
Fig. 1 is the block diagram of the general structure of paging receiver.
Fig. 2 is the block diagram of illustration paging receiver of the present invention.
Below referring to a description of drawings most preferred embodiment of the present invention.
Fig. 2 is the block diagram of illustration paging receiver of the present invention.Radio-frequency (RF) Receiving Device 200 detects the voltage level of the radiofrequency signal of receiving by antenna, it is added on the A/D converter 202, radio frequency voltage of signals level is carried out demodulation, and the voltage level waveform transformation with demodulation becomes numerical data then, thereby numerical data is added on the controller 204.A/D converter 202 produces the numerical data of respective voltage level value, thereby numerical data is added on the controller 204.Controller 204 carries out total control operation as described above, and uses the output of A/D converter 202 to detect the RSSI level according to the setting of RSSI display mode, thereby by display 208 the RSSI level is shown.The key value of setting the RSSI display mode is added on the controller 204 by the key entry device 206 with the required general key button of paging receiver.
The following describes the operational instances of Fig. 2.
Its voltage level of radiofrequency signal of receiving by antenna is added to A/D converter 202 by radio-frequency (RF) Receiving Device 200 after radio-frequency (RF) Receiving Device 200 detects.Then, carry out demodulation by 200 pairs of voltage levels of radio-frequency (RF) Receiving Device, waveform shaping is added to controller 204 after becoming numerical data.Simultaneously, A/D converter 202 produces the numerical data of the voltage level analog value with radio-frequency (RF) Receiving Device 200 outputs, thereby numerical data is added on the controller 204.
In said process, if the user is set at general reception standby mode by keying in device 206 with the RSSI display mode, the detected RSSI level of data value that controller 204 just shows according to A/D converter 202 outputs at display 208 according to the RSSI display mode.At this moment, controller 204 can show the data value of A/D converter 202 outputs with numeral or bar shaped small icon.For example under the situation that data value shows with the form of numeral, if the dateout of A/D converter 202 is 8 bit data, data value just shows with the numeral between 0 to 255.Under the situation that data value shows with bar code form, data value just shows selectively with 0 to 7 striped elongated with grade.
Like this, need not to use independent sensing equipment just can examine the RSSI level of present position at that time.
In sum, paging receiver of the present invention has such benefit, promptly need not to use independent RSSI sensing equipment just can set in the test at the scene, and make the user can more effectively use paging receiver by the RSSI level of detection and demonstration received signal.
Just the present invention thinks that at present some best embodiment describe above, but those skilled in the art are understood that, be to carry out many variations and remodeling to the foregoing description without departing from the scope of the invention, replace corresponding element wherein with equivalence element.
