Abstract

PROBLEM TO BE SOLVED: To significantly reduce the radio wave interference when the same hopping pattern is selected and used between the radio base stations by setting plural different radio frequencies to form a hopping pattern and also setting a constant hopping sequence at least at one of plural base stations and performing the communication between the base stations by means of the switching time of each set and changed radio frequency. SOLUTION: A pattern selection means 15P selects one of hopping patterns which are previously decided at every radio base station 20. At the same time, plural radio frequencies forming a hopping pattern are set at the station 20 together with a constant hopping sequence. Then a switching time setting/ changing means 15t selects and changes the switching time (ti) of each radio frequency, and the radio communication means 11 and 12 communicate with every radio slave station by defining every radio frequency switching time as the set/changed switching time. Thus, the probability of occurrence of the radio wave interference can be significantly reduced between the radio base stations which selected the same hopping pattern.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-level equipment to which a plurality of radio base stations are connected, and a plurality of terminal equipments to each of which a radio slave station is connected. The present invention relates to a wireless communication type data processing device formed to be capable of wireless communication while switching a wireless frequency using a hopping pattern selected from a plurality of hopping patterns with a slave station.

[0002]

2. Description of the Related Art In FIG. 5, for example, a POS system as one form of a wireless communication type data processing apparatus has a plurality of terminal units 30 each composed of an electronic cash register and a higher-level unit called a store controller for collectively managing these terminals. , And are connected to each other so that wireless communication is possible.

[0003] That is, each terminal machine 30A-30M
Performs input / output of merchandise data on merchandise purchased by a customer, calculates and stores the total amount thereof, and performs merchandise sales business processing (data processing) including money transfer / accounting. Host machine 1
No. 0 performs overall management (data processing) by loading various data into each of the terminal devices 30A to 30M and collecting sales data and the like from each of the terminal devices 30A to 30M.

[0004] A plurality (for example, six) of wireless base stations 20A to 20F are connected to the host device 10 via a cable 18C by wire, and each of the wireless terminals 40A to 40M is connected to each of the terminal devices 30A to 30M. Wired connection. 2
9 and 49 are antennas. Generally, in wireless communication,
There are certain restrictions on the radio wave propagation distance for stable communication,
In addition, the transmission speed is lower than that of wired transmission. In this manner, the number of wireless slave stations 40 managed by each wireless base station 20, the installation location of each wireless base station 20, and the like are carefully determined.

[0005] For example, when it is considered that the sales floor 100 shown in FIG. 6 is divided into six areas AR1 to AR6 for convenience and the radio base stations 20 are respectively arranged, for example, the radio base station 20A in the area AR1 And the wireless slave stations 40A, 40
B can communicate wirelessly.

Here, for the radio communication between each radio base station 20 and each radio slave station 40, either a fixed frequency system or a frequency hopping system is adopted. The former is a method of selecting a radio frequency at which radio communication can be stably performed at the time of installation or before opening a store, and setting it as a fixed value. In the latter, the radio base station 20 and the radio slave station 40
In this method, the radio frequency is switched synchronously. Therefore, the degree of noise generated from the electronic devices installed in the store or brought in by the customer, the layout in the store, the number of terminal devices 30 installed,
The latter is adopted when the instability of wireless communication due to the influence of the external radio wave environment (radio wave noise) is strong. This is because there is a high probability that reliable and stable wireless communication can be performed.

That is, the frequency hopping method is shown in FIG.
As shown in (1), a plurality of hopping patterns Pi determined by a plurality of different radio frequencies fi and their hopping order Ni are stored, and one hopping pattern Pi is assigned to each of the radio base stations 20. In each radio base station 20, a switching time set in advance based on the assigned hopping pattern Pi (for example, 400 mSec)
Each time elapses, the radio frequency fi is sequentially switched to perform radio communication with each of the radio slave stations 40.

The switching order and the switching time of each radio frequency fi forming each of the hopping patterns P1 to P5 are constant (for example, f1, f3, f5 every 400 mSec).
... are switched in order. ). Also, once selected, they are fixedly handled.

Thus, for example, the area AR1 shown in FIG.
For example, when the hopping pattern P1 shown in FIG. 7 is selectively set (allocated) to the wireless base station 20A in the area AR2, for example, the hopping pattern P1 is assigned to the wireless base station 20B in the area AR2.
2 is selected and set (assigned). That is, different hopping patterns (P1) in adjacent areas (AR1, AR2)
1, P2) is assigned to avoid radio wave interference.

[0010]

It is well known that usable radio frequency bands are restricted by various circumstances. For example, in the case of the 2.4 GHz band, the number of hopping patterns that can be selected and set is, for example, about 10 types, which is smaller than the number of hopping patterns that can be theoretically constructed (for example, 23 types). Further, depending on the capabilities and scales of the stations 20 and 40, which are restricted in terms of cost and layout, in many cases, for example, five types (P1 to P5) are required as shown in FIG.

Therefore, the six areas AR shown in FIG.
If there are only five hopping patterns P1 to P5 shown in FIG. 7 for 1 to AR6, the same hopping pattern Pi must be selectively set in at least two areas AR. In such a case, two areas (for example, AR1 and AR6) with less radio interference in terms of distance are selected.

However, even if it is selected that there is no radio interference in terms of distance, the area AR1 and the area AR6 have the same radio frequency f1, f3, f5, f5 as shown in FIG.
9,... Are used simultaneously for the same time (switching time). Therefore, for example, the area AR2 on the way
When circumstances such as the wireless communication state of the area AR5 being idle overlap, the stations 20 and 40 of the area AR1 and the area AR6
In some cases, radio interference (crosstalk) may occur between the stations 20 and 40.

An object of the present invention is to provide a wireless communication type data processing apparatus capable of stochastically reducing radio interference when selecting and using the same hopping pattern.

[0014]

According to a first aspect of the present invention, there is provided a high-level equipment to which a plurality of wireless base stations are connected, and a plurality of terminal equipments each to which a wireless slave station is connected. A wireless communication type data processing device formed so as to be capable of wireless communication while switching a radio frequency using a hopping pattern selected from a plurality of hopping patterns between the station and each of the wireless slave stations; A base station is formed so as to be capable of wireless communication with the same selected hopping pattern, and at least one of the wireless base stations is made to have a plurality of different radio frequencies forming the hopping pattern and their hopping order invariable and to change the setting. Wireless communication using the switching time of each radio frequency.

According to this invention, for example, when two radio base stations A and B select the same hopping pattern and perform radio communication, one radio base station A uses the selected hopping pattern as it is and uses the other hopping pattern as it is. Wireless base station B
Then, a plurality of radio frequencies forming the hopping pattern and the switching time of each radio frequency whose setting has been changed without changing the hopping order are used.

That is, one radio base station A changes the radio frequency fi in a predetermined order (for example, f1, f2, f3) every predetermined switching time (for example, 400 mSec).
…) To switch. The other radio base station B has a radio frequency fi
And the switching order is the same (f1, f2, f3,...), But the switching time is, for example, 380 mSec. Therefore,
The same radio frequencies f1, f2, f3, ..., fn-1, fn
, 360, 340, ..., 40, 2
0 mSec, and when one is fn, the other is fn
The same radio frequency can be prevented from overlapping at all so as to be 1.

Therefore, with the radio frequencies of the hopping pattern and the switching order unchanged, the time ΔT ((eg, ΔT = T / 10 ) Can be greatly deleted, so that the probability of occurrence of radio wave interference between both A and B can be greatly reduced.

Further, the invention according to claim 2 comprises a host device to which a plurality of radio base stations are connected, and a plurality of terminal devices to which radio slave stations are connected, respectively. In a wireless communication type data processing device formed to be capable of wireless communication while switching a wireless frequency using a hopping pattern selected from a plurality of hopping patterns with a wireless slave station, each wireless base station side A pattern selecting means for selecting one of a plurality of predetermined hopping patterns, a plurality of different radio frequencies forming the selected hopping pattern and a setting change of a switching time of each radio frequency while keeping their hopping order invariable Switching time setting changing means for performing the setting, and setting the switching time of each radio frequency of the selected hopping pattern as the switching time after the setting change, with each of the wireless slave stations. Provided a setting change after the wireless communication means for line communication, characterized in that.

According to this invention, for example, when the same hopping pattern is selected on the wireless base stations A and B using the respective pattern selecting means, for example, on the wireless base station B side, the same hopping pattern is selected using the switching time setting changing means. Only the switching time forming the hopping pattern is, for example, 400 mSec.
From 380 mSec to 380 mSec. Then, the setting-changed radio communication means on the side of the radio base station B makes the radio frequencies forming the selected hopping pattern and their switching order unchanged, and performs radio communication only with the switching time as the changed switching time. The wireless base station A performs wireless communication according to the selected hopping pattern.

Therefore, in the same manner as in the first aspect of the present invention, the time when the same radio frequency overlaps within the time T required for N times the hopping period while each radio frequency and the switching order of the hopping pattern remain unchanged. △ T
(For example, ΔT = T / 10) can be largely deleted, so that the probability of occurrence of radio wave interference between both A and B can be significantly reduced.

Further, according to the invention of claim 3, each wireless base station is formed so as to be able to transmit the selected hopping pattern and the switching time after the setting change to each of the wireless slave stations, and each of the wireless slave stations has This is a wireless communication type data processing apparatus which is formed so that the setting can be automatically changed between the received selection hopping pattern and the switching time after the setting is changed.

In this invention, the radio base station that has changed the setting of only the switching time in the hopping pattern transmits the selected hopping pattern and the switching time after the setting has been changed to each of the wireless slave stations. Upon receiving this, each wireless slave station automatically changes the setting of the selected hopping pattern and the switching time after setting change instead of the hopping pattern up to now.

Therefore, in addition to providing the same operation and effect as the case of the second aspect of the present invention, since the coordination between the radio base station and each radio slave station can be automatically performed, the handling is much easier.

ec) only after changing the setting time t2 (380 mSe
Wireless communication is performed as c). One cycle INT2 in this case
Is 3,800 mSec (= 380 × 10).

Therefore, the radio base station 20A (AR1)
