Abstract

PURPOSE:To reduce the production cost and the maintenance cost of a receiver by providing an operation detecting part which converts an optical signal to an electric signal to output it to a computer and a light emitting part controlled by the computer. CONSTITUTION:Under the control of a computer 1, an encoder 2 generates an encoded signal, and the carrier wave generated by a signal generator 3 is modulated by the encoded signal generated by the encoder 2 and is sent to a transmission antenna 4. The radio wave transmitted from the transmission antenna 4 is received by a selective call receiver 5 with the display function, and received display information is displayed. The computer 1 recognizes the operation state of the receiver 5 through an operation detecting part 6 by a flicker indicator lamp and a display device of the receiver 5. When the receiver 5 performs the receiving operation, the computer 1 controls a light emitting part 7 to cause it to emit light with a preliminarily determined pattern and transmits the optical signal to the receiver 5. The receiver detects this optical signal to clear the reception state and enters into the reception state again.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wireless selective calling receiver testing method, and more particularly to a wireless selective calling receiver testing method that can be applied to a wireless selective calling receiver with a display function.

[Common technology]

Generally, a radio selective call receiver needs to undergo a receiving operation test during manufacturing or maintenance to evaluate its performance. Here, the receiving operation test means checking flicker display, etc. performed by the receiver as a receiving operation. In particular, in the case of a wireless selective calling receiver with a display function, it is necessary to check the flicker operation of the flicker indicator light as well as the display information displayed on the display and perform a reception operation test.

FIG. 2 is a block diagram showing an example of a wireless selective calling receiver with a display function.

A receiving antenna 21 that receives radio waves, a radio unit 22 that inputs the radio waves and outputs a demodulated signal, a waveform shaping circuit 23 that inputs the demodulated signal and converts it into a decoded signal, and a storage unit that stores a self-calling number. 24, and controls the storage unit 24 to separately output a low frequency flicker signal and display information following the self-calling number when the self-calling number to be called and the individually selected calling number in the decoded signal match. , and a decoder 2 having a clear terminal for erasing received information from the outside.
5, a clear 5W 26 connected to the clear terminal of the decoder 25 for instructing the decoder 25 to delete received information from the outside, and a display 2 for inputting and displaying the display information.
7, a display illumination section 28 that illuminates the display 27, a light amount detector 29 that detects the amount of external light and outputs a light amount signal a according to the amount of light, and a light amount detector 29 that inputs the light amount signal a and lights the display illumination section 28. A lighting control unit 30 to control, a clear terminal control unit 31 to input the light amount signal a and control the clear terminal of the decoder 25, and a flicker indicator lamp 3 to operate by inputting the flicker signal.
2.

Next, the operation will be explained.

The receiving antenna 21 receives a carrier wave modulated with the individual selective calling number and the display information that follows it, and the radio section 22 demodulates the carrier wave and outputs a demodulated signal.

The waveform shaping circuit 23 converts this demodulated signal into a decoded signal which is a digital signal and outputs it. A self-calling number is stored in advance in the storage unit 24, and is read out under the control of the decoder 25. The decoder 25 compares this self-calling number with the individual selective calling number in the decoded signal, and if they match, separately outputs a flicker signal and display information following the self-calling number. The display 27 displays characters, numbers, symbols, etc. in response to display signals.

The flicker indicator lamp 32 performs a flicker operation based on this flicker signal. The light amount detector 29 converts the external light amount into a light amount signal a and outputs it.

The illumination control section 30 receives the light amount signal a, and if a predetermined amount of light is obtained, controls the display illumination section 28 to turn off the illumination. If the predetermined amount of light cannot be obtained, the display illumination section 28 is controlled to turn on the illumination.

In a wireless selective call receiver, once a reception operation is performed, the state is maintained and the reception operation is not performed for subsequent calls.

The clear 5W26 is provided to make the signal receivable again, and when it is turned on, the decoder 25 detects it and becomes receivable again.

The clear terminal control section 31 inputs the light amount signal a, and when the changing pattern matches a predetermined pattern, creates the same state as when the clear 5W 26 is turned on and inputs it to the clear terminal of the decoder 25. . Decoder 25
detects this, clears the received information, and enters the ready state again.

[Problem to be solved by the invention]

In the conventional wireless selective calling receiver test method described above, a clear S-field pressing mechanism is required in order to make the receiver capable of receiving data again after receiving data, and these devices are expensive. Also, due to the presence of moving parts, the failure rate is high and therefore the measurement costs are high. Therefore, there is a disadvantage that the manufacturing and maintenance costs of the receiver are high.

In addition, the receiver and the clear S-field pressing mechanism must be precisely positioned, and the manufacturing and maintenance costs are high due to the equipment.

The computer 1 uses the motion detection section 6 to detect the receiver 5.
The operating state of the receiver 5 is recognized from the flicker indicator light and display. If the receiver 5 is performing a receiving operation, the computer 1 controls the light emitting unit 7 to emit light in a predetermined pattern and transmits an optical signal to the receiver 5.

Receiver 5 detects this optical signal, clears the reception state,

While changing the output level set to signal generator 3,
Repeat this to confirm the receiving operation of Receive@5.

By sending out a predetermined pattern of optical signals from the light emitting section 7 and having the light amount detector 29 receive them, the receiver can be made ready to receive signals again.

〔Effect of the invention〕

The wireless selective calling receiver test method of the present invention provides a light emitting section instead of a mechanical rear S-field pressing section, so that a receiver that has once performed a receiving operation can receive the signal again without any mechanical processing. Since it can be enabled, the measurement system can be constructed at low cost, and since there are no moving parts, there are fewer failures and the measurement cost is low.

Therefore, the manufacturing and maintenance costs of the receiver are low.

Furthermore, since there is no need to precisely position the receiver relative to the measurement system, manufacturing and maintenance costs are further reduced.
