atic Vehicle Monitoring S
The present invention relates to improvements to the data collection method of the Japanese system.
（従来技術とその問題点）
ＡＶＭ システムは基地局と多数の移動局が無線回線
で構成される。このＡＶＭシステムで基地局において移
動局側のデータを収集゛する方式は多数提案されている
がその一つに任意発呼方式がある。(Prior art and its problems) The AVM system consists of a base station and a large number of mobile stations using wireless lines. Many methods have been proposed for collecting data on the mobile station side at the base station in this AVM system, one of which is an arbitrary calling method.
任意発呼方式は基地局側の動作とは全く関係なく移動局
側の操作者が任意にスイッチ等を操作することによって
データを送信できるもので１例えばタクシ−の場合では
空車になった時点で乗務員がスイッチを操作して自局の
車両番号及び所在地区等のデータを基地局へ送信して登
録し、また実車となった時点で乗務員がスイッチを操作
して自局の車両番号及び取消等のデータを基地局へ送信
して登録を抹消する。この任意発呼方式は移動局の動態
が変化する都度９乗務員のスイッチ操作が必要である欠
点があるが、動態の変化頻度が少く。The arbitrary calling method allows the operator of the mobile station to transmit data by arbitrarily operating a switch, etc., regardless of the operation of the base station.1For example, in the case of a taxi, when the car becomes empty. The crew operates a switch to send and register data such as the vehicle number and location of their own station to the base station, and when the vehicle becomes an actual vehicle, the crew operates a switch to transmit data such as the vehicle number and location of their station to the base station and cancel the vehicle. data to the base station to cancel the registration. This arbitrary call origination method has the disadvantage that it requires switch operations by nine crew members each time the dynamics of the mobile station changes, but the frequency of changes in dynamics is low.
かつ個人の意志を重要視する面から見て有利な運用方式
である。しかしながら、この方式は任意のタイミングで
データの送信が行われるため、移動局数が多くなると他
の局のデータ送信及び通話との電波の輻岐の頻度が高く
なり、送信したデータが基地局で受信されない不具合が
生ずる。It is also an advantageous operating method from the perspective of placing importance on the will of the individual. However, with this method, data is transmitted at arbitrary timings, so as the number of mobile stations increases, the frequency of radio waves converging with other stations' data transmissions and calls increases. A problem occurs in which the data is not received.

The purpose is to

て送信が行われ、Ｈの期間の起動スイッチ入力は即。Also, C indicates the state in which the base station is transmitting a signal; D
indicates that no signal is being sent. The signal sent from the base station serves to synchronize the timing of all mobile stations and to determine whether the base station is transmitting. Note that since the wireless line is of a half-duplex system, the base station radio is always in a transmitting state, and even in the transmitting state it can receive radio waves from mobile stations. E indicates a period during which the mobile station side can transmit for a telephone call but cannot transmit a data signal, and F indicates a period during which the mobile station cannot transmit for a telephone call but is capable of transmitting a data signal. G and H indicate slots of the mobile station, G indicates a period during which activation switch input for data signal transmission is stored, and H indicates a period during which the data signal is actually transmitted. Note that the inputs accepted and stored in the period G are randomly distributed and transmitted to the slots in the period H, and the activation switch input in the period H is immediate.

電波で送信する。3 is a control device. The radio waves from the base station are sent to the antenna switcher 4 of the anti-1 and radio device 2. Received by the receiver 5, this signal is demodulated by the demodulator 7 of the control device 3, further decoded by the decoder 8, and the signal detector 9 detects whether or not the base station is transmitting and determines the timing. Extraction is performed, and each signal is sent to the transmission control section 11. The transmission control unit 11 synchronizes the timing of the slots using the timing extraction signal, and controls the transmission of the data signal depending on the presence or absence of the base speed busy signal. In other words, the data generated by the data generation unit 12 based on the settings of the switch setting unit 13 will be transmitted in the slot of the switch setting if the switch setting of the switch setting unit 13 is performed while the base station is transmitting. The generated data is modulated by the modulator 10 and transmitted to the radio device 2.

Similarly, data signals are transmitted to the base station.
