する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a receiver with field strength indication in a mobile radio communication device, and in particular, when the mobile radio communication device is outside the communication range, it moves into the communication range. The present invention relates to a receiver with an electric field strength indication that indicates the state of the received electric field level as a guideline for the reception.

検出機能のある受信機を備えた装置が多い。2. Description of the Related Art In-vehicle or portable mobile radio communication devices are commonly used that communicate by transmitting and receiving radio waves between a radio base station located in a communication service area and a mobile station. Moreover, many of these mobile radio communication devices are equipped with a receiver having a function of detecting the strength of a received electric field from a radio base station.

機能となっている。Conventionally, this type of field strength indicating receiver determines that communication is not possible when the received electric field level falls below a certain value, and displays a message indicating that the receiver is out of communication range, such as "1 Unavailable." After that, the function will not be able to communicate until the received electric field level reaches a level that allows communication.

った。With the conventional 1-inch field strength indicator receiver that is connected to two series, the only indication to the user is ``Unavailable'', so when the user wants to move to an area where communication is possible, it is difficult to know which direction to move. The downside was that I didn't know if I should move.
本発明の目的は、移動無線通信装置の使用者が通信可能
圏外から通信可能圏内への移動方向を認知することがで
きる電界強度指示付受信機を提供することにある。An object of the present invention is to provide a receiver with field strength indication that allows a user of a mobile radio communication device to recognize the direction of movement from outside the communicable area to within the communicable area.

表示部とを備えている。The field strength indicating receiver of the present invention includes a receiving section that detects a received electric field of the mobile radio communication device, and a detection output of the receiving section in advance, which is provided in a mobile radio communication device. The device includes a level detection unit that performs averaging at predetermined time intervals, and a level display unit that changes the blinking cycle of the display in response to the level of the average voltage output from the level detection unit.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

出力する。The embodiment shown in FIG. 1 includes a receiving section 1, a level detecting section 2, and a level display section 3. The receiving unit 1 receives radio waves from a base station in a wireless zone where a mobile radio communication device is located, and outputs a received electric field level detection signal. The level detection section 2 inputs the received electric field level detection signal from the reception section 1 and outputs the averaged voltage over a predetermined period of time to the level display section 3.

図である。The level display section 3 changes the period of blinking of the light emitting element in accordance with the level of the averaged voltage from the level detection section 2, and performs a blinking display corresponding to the level of the received electric field level. First, a specific example of the above-mentioned blinking cycle will be explained. FIG. 2 is an explanatory diagram showing the average output voltage of the level detecting section 2 and the blinking cycle time of the level display section 3 at an arbitrary received electric field level.

In the following case, the average voltage of the level detecting section 2 for a predetermined time is 0, and the blinking cycle corresponding to the above-mentioned Vo of the level display section 3 is T. shall be. Thereafter, the received electric field level Eo~E1...E,~

Further, if the setting is made such that To>TI>T2...>To, the higher the received electric field level becomes, the faster the blinking cycle of the level display section becomes. In other words, when the receiver moves in a direction where the received electric field level is high, the blinking period becomes faster, and conversely, when the receiver moves in a direction where the received electric field level is low,
Since the blinking period becomes slower, it is possible to determine the direction in which to move to an area where communication is possible.

がある。As explained above, the present invention provides a display that changes the blinking cycle in accordance with the received electric field level when a receiver with electric field strength indication equipped with a receiving section, a level detecting section, and a level display section is outside the communication range. This has the effect of allowing the user to recognize the direction in which to move to the area where communication is possible by emitting light from the level display section.
