DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmitter and a receiver used for giving instructions such as work instructions and business communication to a building maintenance staff or the like who patrols a multistory building such as a building for multipurpose use. And a patrol communicator in a building.

[0002]

2. Description of the Related Art In a patrol person communication device in a building, patrollers who are in charge of separate tasks such as facilities and security carry a receiver of a calling device. For this reason, it is necessary to provide a transmitter, a receiver, and a patroller communication device in the building in consideration of not giving an alarm to those patrollers who are not in charge of the patroller or taking out a call. Among these, there are the following two means for the patrol person communication device in the building.

The first means is Japanese Patent Application No. 60-129637 and the second means is Japanese Utility Model Application No. 61-137420.
The former employs a means for transmitting a modulated long-wave signal from a transmitter to a premises broadcast line and informing a receiver carried by the patroller to inform a patroller in the building of a facility failure or the like. . In the latter case, when there are a plurality of monitoring devices in the building and there is a patrol person in charge of each, and when the premises broadcasting line is common, a transmitter to be added to each monitoring device and a patrol person in charge of each are used. The pair of portable receivers is a means for allocating and using carriers of different frequencies.

[0004]

When comprehensive monitoring of a building is performed by using the above-described patrol person communication device in a building, the monitoring includes a plurality of different tasks such as an equipment charge item and a security charge item. The patrons in charge of equipment and security are separate from each other. Therefore, the command / alarm group for communicating with the facility patrol person and the command / alarm group for communicating with the security patrol person are different. That is, the person in charge of the equipment does not need a command-related alarm group related to security, and the person in charge of the security does not need the group of command-related alarms related to equipment.

[0005] However, in order to satisfy the above demands by using the above-mentioned first and second means, separate transmitters and receivers having different frequencies are required. When there is a command alarm continuously transmitted, there is also a problem that it is not possible to inform the patroller of what the previous command signal was. In addition, when simultaneously calling a facility and a patroller in charge of security, if a transmitter having a different frequency is used as described above, it is necessary to simultaneously send a command signal to all the transmitters. Further, in the first means, since the signal adopts the DTMF method (a signal based on a combination of a plurality of audible frequencies), when the transmission frequency is changed by the command / alarm group, the frequency of the DTMF is 300 Hz or more.
Since the frequency is 2700 Hz, there is a problem that the combination of a plurality of waves is accompanied by restrictions. In addition, the usable range of carrier waves (frequency at which transmission loss is small) is limited, and a sufficient interval is required between channels to prevent interference with private broadcasting. There is also a problem that only an alarm group can be transmitted.

[0006] In addition to the above-mentioned problems, there is also a problem that the size of the entire apparatus is increased to be economically disadvantageous, and that the use of the transceiver is limited.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and enables selective reception of only a signal corresponding to a command alarm without using a plurality of transmitters, and also enables simultaneous paging. It is an object of the present invention to provide a transmitter, a receiver, and a patrol communicator in a building capable of confirming a command alarm.

[0008]

According to the present invention, in order to achieve the above object, a first invention separates and stores a parallel command signal sent from the outside for each group and uses this as a serial command signal. The command signal is transmitted continuously until a stop command comes. When the command signal of each group changes, the command signal is changed to a new command signal and transmitted. In the second invention, the received serial command signal is converted into a parallel command signal, and when there is a change in the command signal of each group, the command signal is stored in the order in which it was received, and the stored signal is selected to display and warn. Things. According to a third aspect of the present invention, a parallel command signal transmitted from the outside is separated and stored in groups, and the transmitter transmits the parallel command signal as a serial command signal. When the command is changed, the command is stored in order, and the stored signal is selected and received.

[0009]

The parallel command signals are stored separately for each group.
The stored signal is continuously transmitted as a serial command signal until a stop command is received. Further, the received serial command signal is converted into a parallel command signal. Command signals are stored for each group. And if there is a change in the received command signal,
The previously received signal and the newly received signal are stored in order. The stored signal is selected and displayed and alerted by the position of the selection switch. In the case of batch, received signals are displayed and warned in order regardless of the command signal of any group.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a transmitter system diagram. In FIG. 1, reference numeral 1 denotes an input of a parallel command signal sent from the outside, and in order to accurately operate each section of the transmitter, mixed noise is removed. This is a processing circuit for setting a level to a command signal having a normal magnitude. The signal processed by the circuit 1 is supplied to an OR gate 2, individual signal A and B registers 5 and 6, and a strobe signal gate 4. The OR gate 2 detects the command signal shaped by the processing circuit 1 and, when there is a signal in any one of the bits of the command signal, detects that the command has been input. The OR gate 2 sends out a detection output. Then, the control signal oscillator 3 generates a timing pulse for operating each part of the transmitter. Reference numeral 4 denotes a strobe signal gate to which a timing pulse from the oscillator 3 and a command signal from the command signal processing circuit 1 are input. The strobe signal gate 4 generates a command pulse for operating each part of the transmitter when both signals are present.

The individual signal A and B registers 5 and 6 are blocks for storing command signals for each group.
Stores a command signal and a carry signal caused by a signal change (supplied from a register described later). 7 is an individual signal one carry register, and 8 is an individual signal two carry register. These registers 7 and 8 have a command signal received first in the individual signal group A or B, and are later re-entered in the same signal group. When a different signal is received, "1" is added to the contents of the carry registers 7 and 8 for each group in order to carry the receiver display.

Reference numeral 9 denotes a signal transmission command circuit, and 10 denotes a transmission command circuit. Both command circuits 9 and 10 transmit a command signal by a command pulse from the strobe signal gate 4. When the command signal from the signal transmission command circuit 9 is supplied to the parallel-to-serial signal converter 11, the signals from the individual signals A and B registers 5 and 6 are converted into serial pulse signals in accordance with the internal clock pulse to modulate the long-wave signal transmitting unit 12. Give to the bowl. The serial pulse signal is continued until the command signal from the signal transmission circuit 9 disappears. The long-wave signal transmission unit 12 includes a long-wave oscillator, an FS modulator, and a power amplifier, and starts operating when a command signal from the transmission command circuit 10 is supplied. That is, when the serial pulse signal is supplied to the transmission unit 12, the output of the long-wave oscillator is FS-modulated by the serial pulse signal, and the power is amplified to the rated output by the power amplifier. To send to. The output of the transmission unit 12 is continued until the transmission command signal from the transmission command circuit 10 is lost.

The signal transmitted on line 32 is received by the receiver shown in FIG. In FIG. 2, the transmission output guided from the line 32 is captured by the reception antenna 31 and supplied to the long-wave signal reception unit 13. The receiving unit 13 amplifies, limits, and demodulates the received long-wave signal, amplifies the transmitted command serial pulse signal to a required level, and amplifies it to a serial-parallel signal converter 14.
To supply. The serial-parallel signal converter 14 converts the command serial pulse signal sent from the receiving unit 13 into parallel, and stores it until the input signal changes. The output of the converter 14 is supplied to the individual signal register 15. The register 15 and the converter 14 are blocks for storing command serial pulse signals in parallel and storing them in the order in which they are received several times.
If the command block assigned to the receiver is selected to be individual A or B, only the command block is stored in the two-digit register 2
Send to 0. 16 is an individual 1 signal carry register. This register 16 is for carry signal of the individual A command signal group, and the individual 2 signal carry register 17 is for carry signal of the individual B command signal group. , 17 detect and store a change (carry signal) in the command signal group.

Reference numerals 18 and 19 denote an individual one signal digit and an individual two digits.
This is an individual signal selection gate which determines which command signal group is to be selected from the carry signals received by the signal carry registers 16 and 17 by the selector switch 33. These gates 18, 19
Is supplied to the two-digit select gate 21. The gate 21 receives the control signal for supplying only the command signal group to the individual signal register 15, the signal received at the destination where only the number of digits to be displayed on the display 23 is received, and the signal received newly at the destination. It generates a control signal to be displayed in the lower digit. Reference numeral 22 denotes a display segment driver for displaying a command signal on the display 23. Reference numerals 24 and 25 denote alarm gates A and B, which receive a newly received command signal from the two-digit register 20 and output an alarm determined by the signal group. This is a selection gate for giving the sound to the speaker 29 that notifies the circulator. 26 and 27 are alarm signal flicker circuits, and 28 is an alarm signal oscillator. In the above embodiment, the selection by group also includes a selection to receive and display all the groups at the same time, in which case the display order is the display of the previously received command signal regardless of any command signal regardless of the group. Change the position and display the newly received command signal. The following table is based on individual selections by group.

[0016]

As described above, according to the present invention,
The following effects are obtained.

A) The commands received for each alarm group can be separately stored and transmitted simultaneously.

B) The patroler carries a receiver specially set for the assigned task, but the receiver receives only the alert for the assigned task, so that each visitor is confused by the alerts of other tasks. Can be prevented.

C) A paging signal is provided to recall all patrolers at once, and paging is possible when necessary.

D. Since the transmission state is continued until the stop command is input, even if the patrol person passes through the dead zone, he / she can always receive an alarm if he / she enters a receivable position, so that high reliability can be obtained. Can be In the case of a so-called pager, since it is not continuous, it may fail to receive an alarm when passing through a dead zone.

E. The receiver receives the alarm first by transmitting the carry signal, and further confirms, if another signal is received before stopping the transmission, carries the signal to determine what the previous signal was. Can be confirmed, that is, the data can be stored in a so-called last-in first-out manner. In addition, there are various other excellent effects such as the possibility of receiving all alarms depending on the position of the selection switch.
