DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a master station for transmitting a control signal for sounding a siren of a slave station provided in each area by radio to execute a siren notification in a municipal emergency management radio fixed system. About the console.

[0002]

2. Description of the Related Art Conventionally, in this type of municipal emergency radio communication fixed system, there are a motor siren system (F2D system) and a pseudo siren system (F3E system) as a system for sounding a siren in a slave station. Therefore, when executing the siren notification, the master station console outputs a dedicated control signal for a motor siren type slave station, and outputs a dedicated control signal for a pseudo siren type slave station. Was. As described above, conventionally, when the siren system of the slave station is different, the control signal output from the master console is also different.

[0003]

However, in recent years, a plurality of slave stations having different siren systems may be mixed, and in such a system, when a siren notification is issued to each slave station, there is a problem. After sending a control signal to one of the siren type slave stations, it is necessary to send another control signal to the other siren type slave station, and there has been a problem that siren notification cannot be executed at the same time.

An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a master station console which can simultaneously execute siren notification to a plurality of slave stations having different siren systems. And

[0005]

According to the present invention, in order to achieve the above object, a control signal for simultaneously executing a siren notification to a plurality of slave stations having different siren systems is output from a master station console. In this way, siren notification can be simultaneously performed for slave stations of different systems.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (Embodiment) FIG. 1 is a block diagram showing the structure of a municipal disaster management radio fixed systems according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a master station operation console for selecting a target slave station when executing a siren notification. Reference numeral 2 denotes a signal output unit provided in the master station console 1, which, as shown in FIG. 2, outputs control signal data 21 including a motor siren type slave station control signal 11 and a pseudo siren type slave station control signal 12. Generate and output. Reference numeral 3 denotes a wireless device that transmits the control signal data 21 output from the signal output unit 2 from the transmitting antenna 4 as wireless data. Reference numeral 5 denotes a motor siren type slave station, which includes a receiving antenna 6 and a trumpet speaker 7. Reference numeral 8 denotes a pseudo siren type slave station, which includes a receiving antenna 9 and a trumpet speaker 10.

Next, the operation of the above embodiment will be described. The slave station 5 of the motor siren system and the slave station 8 of the pseudo siren system are selected by the master station console 1. Based on this selection, the signal output unit 2 generates control signal data 21 including the control signal 11 for the motor siren type slave station and the control signal 12 for the pseudo siren type slave station as shown in FIG. Output. The wireless device 3 modulates the input control signal data 21 and sends it out from the transmitting antenna 4 as wireless data. The slave stations 5 and 8 receiving the wireless data by the receiving antennas 6 and 9 respectively demodulate the control signal addressed to the own station in the wireless data and output the siren sound from the trumpet speakers 7 and 10.

As described above, according to the above-described embodiment, the wireless device 3 connected to the master station console 1 sends control signals for both the slave station 5 of the motor siren system and the slave station 8 of the pseudo siren system. Since the wireless data including the data is transmitted to the slave stations 5 and 8, siren notification can be simultaneously made to a plurality of slave stations having different siren systems.

[0011]

According to the present invention, as is apparent from the above embodiment, a control signal for simultaneously executing a siren notification is output from a master station console to a plurality of slave stations having different siren systems. This has the effect that siren notification can be simultaneously executed for a plurality of slave stations having different siren systems.

Further, according to the present invention, since siren notification can be simultaneously performed to a plurality of slave stations having different siren systems, a slave station of a system which has been used in the past can be discarded without discarding a slave station of an old system. There is an effect that the slave station can be introduced into the system, and the cost burden in system construction can be reduced.
