EXAMPLES Example 1. An embodiment of the present invention will be described below with reference to the drawings. 1 is a block diagram showing a moving body movement monitoring apparatus according to an embodiment of the present invention. In FIG. 1, 1 is a center computer having a display function, 2 is a base station radio, 3A, 3B, ... , 3N is a sign post transceiver, and 4 is a mobile station radio mounted on a cart that is a mobile body.

Next, the operation will be described. 2 is a timing chart showing a signal flow in the dynamic monitoring of the first embodiment, and FIG. 3 is a timing chart showing a signal flow in a wireless call of the first embodiment. 2 and 3
, F _B is a base station (base station radio), SP is a sign post (sign post transceiver), ML is a mobile station (cart mobile station radio), V _B is a base station voice, SC is a select call signal, VM Is a mobile station voice, T is a call signal, f ₁ is a call wave (first radio channel wave), and f ₂ is a data wave ( _second radio wave).
(Radio channel wave), FS is a synchronization signal, PO is a polling activation signal, and A # 5 is a fifth car cart response signal.

As shown in FIG. 2, the mobile body movement monitoring apparatus configured as described above is provided with a sign post transceiver from a center (which includes the center computer 1) (not shown) via the base station radio 2. The FS signal is sent to 3A to 3N. Signpost transceiver 3 that received the FS signal
Each of A to 3N intermittently transmits its own position data (PO) to the cart mobile station radio 4 at low power in synchronization with the synchronization signal (FS) from the center. Regarding this PO transmission, the center simultaneously activates the sign post transmitter / receiver in a short time and apparently reduces overreach. Then, between the cart mobile station radio 4 and the base station radio 2, a communication channel including at least a radio channel for a call and a radio channel for data (mainly for cart position information) is set.

When the cart mobile station wireless device 4 receives the position data (PO) transmitted from the sign post transceiver in one sign post area, the cart mobile station wireless device 4 sends the position data (PO) to the base station wireless device 2 (cart mobile station). The sign post number and the own station number are transmitted using a data wave different from the call wave at a predetermined transmission timing to the radio device 4). For example, when transmitting the response signal A # 5 of the fifth car, the cart mobile station radio 4 transmits data other than the call wave f ₁ (first radio channel wave) of the caller as shown in FIG. The response signal A # 5 is transmitted (responded) using the wave f ₂ (second radio channel wave). As a result, the response from the fifth car cart can be sent to the center through an independent communication channel.

As described above, when confirming the position of the cart,
The center computer 1 acquires the position information from the data wave f ₂ (second radio channel wave) from the cart mobile station radio 4. Specifically, the center computer 1 identifies the cart number and position based on the sign post number from the base station radio 2 and the station number, and displays the cart number and position. On the other hand, in the call, the call wave f _{1 of the} call main body is used.
(First radio channel wave) is used. As shown in FIG. 3, between the base station radio 2 and each cart mobile station radio, the base station voice V _B and the mobile station voice VM are selected by the cart mobile station radio by the select call signal SC. , It becomes possible to talk with the selected cart mobile station radio device. A call signal T is transmitted on the cart mobile station radio side.

As described above, according to the first embodiment,
By performing the communication of the cart call and the grasping of the position by separate communication channel waves, the movement of the cart can be grasped regardless of the voice call, and the voice call can be well performed.

In the above embodiment, the call and the data (positional information) can be communicated at the same time. However, one of the communication channels between the cart mobile station radio 4 and the base station radio 2 is used. If only the use of the communication wave f ₁ is permitted, the communication wave f ₁ and the data wave f ₂ may be automatically switched. That is, when the cart mobile station wireless device 4 receives the position data (PO) transmitted from the sign post transceiver in one sign post area, the cart mobile station wireless device 4 sends the position data (PO) to the base station wireless device 2 (the cart mobile station wireless device). The communication wave f ₁ is automatically switched to the data wave f ₂ in accordance with a predetermined transmission timing of the machine 4). The sign post number and the own station number are transmitted by the data wave f ₂ . When the cart mobile station radio 4 goes out of the sign post area, the communication channel is automatically switched from the data wave f ₂ to the call wave f ₁ at that timing, and the call channel for the caller is set. It
