Description
SPECIFICATION
A portable emergency-indicating apparatus
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a portable emergency-indicating apparatus for acoustically and/or visually indicating an emergency or abnormality occurring in a predetermined area to a specified person or persons. A portable emergency-indicating apparatus of this type may be employed in an alarm system for protecting a predetermined area, such as the user's residence or office, against unauthorized intrusions, the destruction of or removal of property, fire, equipment failure, etc.
Description of the Prior Art
In a conventional alarm system, a monitoring room or a central alarm-control room is arranged in a predetermined area protected by the alarm system so as to monitor fire, unauthorized intrusions, and other types of emergencies or abnormalities. That is to say, an authorized monitor or monitors in the central alarm-control room can execute necessary alarm operations when an emergency or abnormality occurs. However, if it is necessary for a specified person, such as a controller of the predetermined protected area, to monitor an emergency or abnormality, a monitoring device must be provided in the controller's room. Further, a conventional pocket bell is often used for sounding the alarm for an emergency or abnormality.However, such pocket bell is unable to send a counter signal to the alarm signal and has neither means to indicate the present condition of the predetermined protected area in detail nor means to automatically send a signal without manual operation, In addition, in the conventional alarm system, it is necessary for the authorized monitor to always be in the monitoring room. Therefore, the conventional alarm system is very troublesome. Furthermore, in the conventional system, it is impossible to inform the controller of the emergency or abnormality if he is away from the controller's room, and, as a result, he either cannot immediately or cannot at all execute the necessary action for controlling the emergency or abnormality.
SUMMARY OF THE INVENTION
It is, therefore, an object of the present invention to eliminate the drawbacks encountered in the conventional alarm system.
It is another object of the present invention to provide a portable emergency-indicating apparatus which enables a specified person, e.g., a controller, to immediately be informed of an emergency or abnormality occurring in a predetermined area protected by an alarm system even if the specified person is not in his room.
In accordance with the present invention, there is provided a portable emergency-indicating apparatus capable of intercommunicating with a fixedly arranged security-ensuring apparatus of an alarm system for ensuring the security of a predetermined area. The portable emergency-indicating apparatus comprises: a signal-receiving circuit which receives an emergency-information signal in the form of a modulated and coded signal transmitted from the security-ensuring apparatus; a demodulating circuit, connected to the signal-receiving circuit, for demodulating the emergency-information signal into a coded signal; a discriminating unit arranged so as to effect discrimination of the emergency-information signal on the basis of predetermined signal codes stored in and read out of a memory unit connected to the discriminating unit; a drive circuit arranged so as to be operated upon the receipt of an output signal sent from the discriminating unit; a display unit, capable of being driven by the drive circuit, for displaying and indicating an emergency to a specified person; and a built-in battery means for electrically powering the aforementioned circuits and units.Preferably, the emergency-indicating apparatus further comprises: a switching unit for issuing a drive signal upon being operated by the specified person; a signalgenerating circuit, connected to the switching unit, for generating a modulated and coded signal requesting the security-ensuring apparatus to immediately transmit the emergencyinformation signal in the form of a signal indicative of the current condition of the predetermined area; and a signal-emitting circuit, connected to the signal-generating circuit, for emitting the modulated and coded signal to the security-ensuring apparatus.

Figure 2 is a detailed block diagram of part of the portable emergency-indicating apparatus of Fig. 1;
Figure 3 is a block diagram of a variation of the part of the portable emergency-indicating apparatus shown in Fig. 2;
Figure 4 is a perspective view of the portable emergency-indicating apparatus of Fig. 1, illustrating the apparatus encased in a casing means in a typical portable state; and
Figure 5 is a schematic block diagram illustrating another embodiment of the present invention which is similar to that of Fig. 1.
Referring to Fig. 1, emergency sensors 1 are suitably located in a predetermined area G protected by an alarm system. The sensors 1 sense diverse types of emergencies or abnormalities, such as fire, unauthorized intrusions, gas leakage, equipment failure, etc. The emergency sensors 1 are commonly connected to a security-ensuring apparatus 2 which is fixedly installed in a predetermined place in the protected area G, such as an alarm-control room.
The construction and function of the securityensuring apparatus 2 is disclosed in a copending application in the name of Shiro
Shirai et al. The security-ensuring apparatus 2 is provided with a signal-transmitting and signal-receiving antenna 3. An antenna 4 is provided with a portable emergency-indicating apparatus 5 of the present invention. The antennas 3 and 4 cooperate to enable intercommunication between the security-ensuring apparatus 2 and the portable emergency-indicating apparatus 5.
When one or more emergency sensors 1 sense an emergency or abnormality in the protected area G, the security-ensuring apparatus 2 first issues a coded and modulated emergency-information signal, which includes a pilot signal which continues for several seconds, and then issues an emergency signal. The emergency-information signal is transmitted through the antenna 3.
The emergency-indicating apparatus 5 comprises: a signal-receiving circuit 51 which receives a radio signal received by the antenna 4; a signal-demodulating circuit 52 connected to the signal-receiving circuit 51; a discriminating unit 53; a memory unit 56 connected to the discriminating unit 53; a drive circuit 55 which, when operated by the discriminating unit 53, drives a display unit 56 which acoustically or visually indicates an emergency or abnormality; and first and second electric power units 57 and 58, respectively, comprised of electric batteries. The apparatus 5 further comprises a solenoid relay RR and a pulse oscillator OSC, both being connected to the first electric power unit 57, and another solenoid relay RD connected to the drive circuit 55. The relay RR has a normally open contact rr, and the relay RD has two normally open contacts rdl and rd2.The pulse oscillator OSC always generates electric pulses, each having a width of scores of milliseconds. The frequency of the pulses is designed so as to be shorter than the time period for which the above-mentioned pilot signal continues. The electric pulses generated by the pulse oscillator intermittently energize the solenoid relay
RR. As a result, the contact rr of the relay RR is intermittently closed so that the electric power of the first electric power unit 57 is intermittently supplied to the signal-receiving circuit 51 via the contact rr. The closing frequency of the contact rr exactly corresponds to the frequency of the electric pulses.
With the intermittent supply of electric power to the signal-receiving circuit 51, the circuit 51 is able to receive the pilot signal of the emergency-information signal transmitted from the security-ensuring apparatus 2 via the antennas 3 and 4. The received pilot signal, in the form of a coded and modulated radio signal, is then demodulated by the demodulating circuit 52 and is sent to the discriminating unit 53. Upon receipt of the demodulated pilot signal, the discriminating unit 53 discriminates whether or not the demodulated pilot signal is a true pilot signal transmitted from the security-ensuring apparatus 2 on the basis of a predetermined pilot-signal code stored in the memory unit 54.When it is discriminated that the demodulated pilot signal is a true pilot signal, the solenoid relay RR connected to the first electric power unit 57 and a solenoid relay RS connected to the second electric power unit 58 are immediately and concurrently energized for a preselected time period, e.g., for approximately ten seconds. Therefore, the apparatus 5 is able to receive, after the pilot signal, an emergency signal, having a width of several hundred milliseconds, transmitted from the securityensuring apparatus 2.
Referring to Fig. 2, which illustrates the detail that internal arrangement of the abovementioned discriminating unit 53 and memory unit 54, the unit 53 comprises: a pilotsignal discriminating circuit 531 for discriminating whether or not the pilot signal is a true pilot signal; a code-correspondence discriminating circuit 532 for discriminating whether or not the emergency signal of the emergency-information signal contains codes peculiar to the present apparatus 5 and its user; an emergency-discriminating circuit 533 for discriminating from the emergency signal of the emergency-information signal the type of emergency; three addressing circuits 534, 535, and 536; a timer circuit 537 connected to the pilot-signal discriminating circuit 531; and a drive circuit 538 for driving the solenoid relay RS having a contact rs arranged in the signal line to the code-correspondence discriminating circuit 532. The memory unit 54 comprises a memory circuit 541 for storing therein a pilot-signal code, a memory circuit 542 for storing therein codes peculiar to the present emergency-indicating apparatus 5 and its user, and a memory circuit 543 for storing therein predetermined types of emergency codes. The memory circuit 541 is arranged so as to supply the pilot-signal code to the pilot-signal discriminating circuit 531 when a readout signal is sent from the circuit 531 via the addressing circuit 534.A similar arrangement is provided for a combination of the memory circuit 542, the code-correspondence circuit 532, and the addressing circuit 535, as well as that of the memory circuit 543, the emergency-discriminating circuit 533, and the addressing circuit 536.
Referring to Fig. 1 and Fig. 2, the signalreceiving circuit 51 receives the emergency signal subsequence to the pilot signal and sends it to the discriminating unit 53 through the demodulating circuit 52. Therefore, while the contact rs in the unit 53 is closed for the predetermined time period set by the timer circuit 537, the demodulated emergency signal is sent to the code-correspondence discriminating circuit 532. At this stage, it should be understood that the demodulated emergency signal contains therein the user's code for discriminating the user of the apparatus 5, the machine code for discriminating the apparatus 5 per se, and an emergency code for discriminating different types of emergencies.Therefore, when the demodulated emergency signal enters into the circuit 532, it is discriminated whether or not this signal is a true emergency signal to be sent to the present emergency-indicating apparatus 5 on the basis of the predetermined codes read out of the memory circuit 542 to the circuit 532. When it is discriminated that the demodulated emergency signal is a true emergency signal, the signal is further sent to the emergency-discriminating circuit 533, where the type of emergency is further discriminated based on the predetermined codes read out of the memory circuit 543. Thereafter, the discriminated emergency signal is sent to the drive circuit 55 of the display unit 56. When the drive circuit 55 receives the discriminated emergency signal, the circuit 55 operates the solenoid relay RD so that the contacts rdl and rd2 thereof are closed.As a result, electric power is supplied from the second electric power unit 58 to the display unit 56 via the closed contact rd2. Thus, the emergency signal sent from the discriminating unit 53 via the drive circuit 55 and the closed contact rd1 is displayed on the electrically-powered display unit 56. That is, the alarm lamps or buzzers of the display unit 56 are operated so as to indicate the occurrence of an emergency as well as the type of emergency. For example, an alarm lamp indicating a fire is lit.
Since a specified person, such as a controller, is therefore made aware of the emergency, he can execute the necessary action to bring it under control, such as telephoning outside of the protected area G to a police station, fire station, etc. and using other signal-transmitting devices to request assistance in bringing the emergency in the protected area G under control. Naturally, the controller can intercommunicate with monitoring engineers in the monitoring room in order to give appropriate commands to the monitoring engineers.
The indication of an emergency on the display unit 56 of the portable emergencyindicating apparatus 5 is terminated when another emergency-information signal indicating that the emergency has been brought under control is transmitted from the securityensuring apparatus 2 to the apparatus 5. That is, the emergency-information signal transmitted from the apparatus 2 includes a pilot signal and an emergency-under-control signal containing therein the user's codes, the machine code, and an emergency-under-control code.
The emergency-information signal received by the signal-receiving circuit 51 is processed in the apparatus 5 in the same manner as the previously described emergency-information signal indicative of the occurrence of an emergency. As a result, when it is discriminated that the emergency-under-control signal of the emergency-information signal is a true emergency-under-control signal, the signal is sent to the drive circuit 55. Thus, upon the receipt of the true emergency-under-control signal, the drive circuit 55 de-energizes the solenoid relay RD so as to open the contacts rd1 and rd2. Accordingly, the power supply from the second electric power unit 58 to the display unit 56 is stopped, and the emergency display on the display unit 56 is terminated.
Various modifications may be made in the portable emergency-indicating apparatus 5.
For example, the display unit 56 may be comprised of a liquid crystal displayer or a cathode-ray tube (CRT) displayer and a loudspeaker mechanism so that the site of the emergency is distinctly displayed on a map of the liquid crystal displayer or the CRT displayer. The type of emergency may be displayed by the use of symbols, characters, letters, words, etc. Further, the emergency can be broadcast over the loudspeaker if it is a fire.
In the case where the display unit 56 comprises a liquid crystal displayer or a CRT displayer, the discriminating unit 53 and the memory unit 54 have to be modified so as to correspond to the units 53' and 54' illustrated in Fig. 3.
The memory unit 54' is different from the unit 54 in that a site-information converting circuit 539a, a display-pattern selecting circuit 539b, and an addressing circuit 539c are additionally arranged. The site-information converting circuit 539a is connected to both the code-correspondence discriminating circuit 532 and the emergency-discriminating circuit 533. The display-pattern selecting circuit 539b is connected to both the emergencydiscriminating circuit 533 and the site-information converting circuit 539a.
The memory unit 54' is also different from the unit 54 in that an additional memory circuit 544 stores therein codes of display patterns predetermined on the basis of different types of emergencies. The memory circuit 544 supplies the display-pattern codes to the display-pattern selecting circuit 539b when a readout signal is sent from the circuit 539b to the circuit 544 via the addressing circuit 539c.
The site-information converting circuit 539a operates so as to generate a signal indicating the site of an emergency within the predetermined protected area G when the signals from the code-correspondence discriminating circuit 532 and the emergency-discriminating circuit 533 are input into the circuit 539a. The site signal is then sent to the display-pattern selecting circuit 539b, where the type of symbol or word to be displayed on the display unit 56 is selected, on the basis of the display-pattern codes supplied from the memory circuit 544.
The portable emergency-indicating apparatus 5 of the present invention may be cooperated with the security-ensuring apparatus 2 by use of the method of ultrasonic transmission of infrared transmission instead of the described method of radio transmission.
It should be understood that indication of the type of emergency, such as a fire, an unauthorized intrusion, etc. is not indispensable. For example, the display unit 56 may be provided with a single alarm lamp which is lit when there is an emergency and which is turned off when the emergency is under control.
Fig. 4 illustrates an example of the whole configuration of the portable emergency-indicating apparatus of the present invention. In the example of Fig. 4, the apparatus 5 is assembled into a piece of compact electronic desk equipment encased in a casing 100 having a flat bottom face and a top face 102 slanted forward and formed as a display panel. That is, in the slanted top face 102, a loudspeaker 104 and a liquid crystal displayer 106 are accommodated and a buzzer-stop button 108 is arranged. The signal-receiving antenna 4 is arranged on a side of the casing 100. Therefore, when the portable emergency-indicating apparatus encased in the casing 100 is placed on the controller's desk, the controller can readily watch the display panel and operate the button 108. If necessary, the controller may carry the apparatus with him since it is compact and light in weight.As a result, the controller can immediately execute a necessary action if an emergency or abnormality occurs in the predetermined protected area G.
It should be noted that the present apparatus can receive not only an emergency-information signal automatically transmitted from the security-ensuring apparatus 2 but also a different emergency-information signal transmitted from the apparatus 2 when the apparatus 2 is manually operated by monitoring engineers.
Fig. 5 illustrates a portable emergency-indicating apparatus according to another embodiment of the present invention.
The portable emergency-indicating apparatus 1 5 of Fig. 5 is different from the apparatus 5 of Fig. 1 in that it has a signaltransmission function in addition to a signalreceiving function similar to that of the apparatus 5. Therefore, the emergency-indicating apparatus 1 5 is provided with an antenna 14 capable of receiving a radio signal transmitted from a security-ensuring apparatus 2 via an antenna 2 as well as of emitting a radio signal as described hereinafter to the security-ensuring apparatus 2.That is, the emergencyindicating apparatus 1 5 is constructed so that when a controller or another specified person carrying the present apparatus 1 5 wishes to determine the current condition within a predetermined area protected by an associated alarm system, the controller or another specified person can operate the apparatus 1 5 so as to emit to the security-ensuring apparatus 2 a radio signal which requests the apparatus 2 to transmit a current emergency-information signal. The current emergency-information signal transmitted from the apparatus 2 must include the user's code, the machine code, an emergency or abnormality code, a normality code, and a type-of-emergency indicating code.If necessary, the current emergencyinformation signal may further include an emergency-site code indicating in what part of the predetermined area an emergency exists if indeed one does exist.
So that the current condition can be determined, the emergency-indicating apparatus 1 5 comprises; a switching unit 61 to be operated by the controller or another specified person; a signal-modulating circuit 62, connected to the switching unit 61, for generating a modulated and coded signal in response to a drive signal issued from the switching unit 61; and a signal-emitting circuit 63 for emitting the modulated and coded signal of the signal-modulating circuit 62 by means of the antenna 14. The modulated and coded signal includes the user's code, the machine code of the present apparatus 15, and a code indicating that this signal is a signal for determining the current condition of the predetermined protected area.
When the emitted signal is received by the security-ensuring apparatus 2 via the antenna 3, it is subjected to a discriminating operation by the apparatus 2. As a result, when it is discriminated that the signal is a true signal emitted from the present emergency-indicating apparatus 15, the apparatus 2 immediately transmits the aforementioned current emergency-information signal. The current emergency-information signal is received, via the antenna 14, by a signal-receiving circuit 151 of the apparatus 15. The signal is further forwarded, via a signal-demodulating circuit 152, to a discriminating unit 1 53. In the discriminating unit 153, the current emergency-information signal is processed so that it can be discriminated whether or not it is a true emergency-information signal transmitted to the present apparatus 1 5 on the basis of the predetermined user's code and machine code preliminarily stored in a memory unit 1 54. The current emergency-information signal is also processed by the discriminating unit 1 53 so that it can be discriminated, on the basis of the predetermined type-of-emergency codes stored in the memory unit 154, whether the current condition of the predetermined protected area is a normal condition or whether ain emergency or abnormality exists.
In the case of an emergency or abnormality, it is also discriminated what type of emergency or abnormality has occurred in the area. After the above-mentioned processing, the current emergency-information signal is further sent, via a drive circuit 155, to a display unit 156, which comprises alarm lamps capable of lighting so as to indicate an emergency, as well as the site of the emergency, and a buzzer capable of sounding so as to indicate an emergency. Thus, the controller can easily determine the current condition of the predetermined protected area. Accordingly, if necessary, the controller can immediately take a security-ensuring action, such as informing a fire station, a police station, etc., of the emergency by the use of a telephone or another appropriate alarm information system.It should now be understood that according to the portable emergency-indicating apparatus 1 5 of the present embodiment, a controller or a specified person is able to have improved intercommunication with the security-ensuring apparatus 2 fixedly arranged in the monitoring room of the predetermined protected area.
It should naturally be understood that when the security-ensuring apparatus 2 transmits an emergency-information signal in response to the sensing of an emergency or abnormality by the emergency sensors 1, the emergencyinformation signal is received and processed by the emergency-indicating apparatus 1 5 in a manner similar to that of the emergencyindicating apparatus 5 of Fig. 1. Therefore, for the sake of brevity, a description of the processing of such emergency-information signal by the apparatus 1 5 is omitted here.
It should further be understood that the emergency-indicating apparatus 1 5 of the present embodiment may also employ the method of ultrasonic transmission or infrared transmission instead of the described radio transmission method.
It should also be understood that the display unit 1 56 may comprise a liquid crystal displayer or a CRT displayer and a broadcasting system instead of the described alarm lamps and buzzers. In addition, the apparatus 1 5 can be encased in a small casing similar to the casing 100 of Fig. 4 so that the liquid crystal displayer or CRT displayer and the loudspeaker of the broadcasting system are fitted into an appropriate front panel of the casing.
From the foregoing description of the preferred embodiments of the present invention, it will be understood that according to the present invention, there is provided a portable emergency-indicating apparatus used with an alarm system for ensuring the security of a predetermined area, which apparatus is compact and light in weight and is capable of immediately indicating to a specified person that an emergency has occurred in the predetermined area even if the specified person is absent from his room.
