Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a system for monitoring work in life-threatening environments.

[Conventional technology]

In workplaces such as the bottom of tankers and inside drainage pipes, toxic gases remain or are generated, posing a constant threat to the lives of workers. Conventionally, as a safety system in such dangerous work areas, workers have a wireless transmitter, and when they feel physically abnormal, they can activate a part of the sensor such as a switch attached to it. , the abnormal situation was notified to the receiver side via radio.

[Problem to be solved by the invention]

With the conventional technology described above, depending on the type of poisonous gas, the motor center is first paralyzed, so even if the user is aware of an abnormal situation, they are unable to operate switches, etc. Unable to alert people, they often died from inhaling the poisonous gas. The present invention has been made in view of the above, and its purpose is to provide a monitoring system that periodically checks the level of consciousness of workers during work in environments that pose a danger to life. Another purpose is to notify workers from the terminal of the regular alarm time, and another purpose is to notify the workers of the elapsed time from the regular alarm time. The goal is to ensure that workers can operate the sensor during the periodic alarm time.

[Means to solve problem a]

In order to achieve the above object, the present invention comprises a terminal equipped with a sensor and a terminal transmitter, and a receiving section equipped with a receiver, a signal processing section, and an alarm, the sensor being a mechanical switch, When the mechanical switch is manually pressed, a predetermined signal is emitted from the terminal transmitter, and the receiving section monitors the time interval between the alarms from the terminal and determines when the last alarm from the terminal is received. If the next alarm is not received within a predetermined time calculated from , the alarm will notify you, and if it is received within the predetermined time, the system will enter a monitoring state again starting from that time. In addition, the terminal is equipped with a terminal annunciator,
This system notifies the terminal operator that the time for periodic notification has arrived by using various stimuli such as sound, light, and vibration, and also indicates the elapsed time since entering the time period for periodic notification. The device has a means for notifying the terminal Wi forger.

[Effect]

The monitoring system configured as described above issues periodic alarms by pressing a mechanical switch within a predetermined time counting from the last periodic alarm, and after receiving the last periodic alarm at the receiver, Monitor whether regular alerts are issued within a predetermined time. If the terminal operator is normal, regular notifications will be issued.
After repeated monitoring, if the mechanical switch is not turned off within a predetermined period of time, an anomaly is assumed to have occurred, and an alarm in the receiving section is used to notify the operator and a rescue operation to arrange rescue is started. Furthermore, by providing the terminal with a timer function and adding a terminal annunciator to inform the terminal of the periodic notification, it is possible to inform the terminal operator of the timing of the periodic notification. Furthermore, by providing a means for informing the terminal operator of the elapsed time since the time when the periodical alarm should be issued, the remaining time until the periodic alarm is to be issued can be displayed. [Example] An example will be described with reference to the drawings. In Figure 1,
Terminal +l1i1 has sensor 2 and terminal transmission fi3! 4
:@shi, The receiving unit 4 is equipped with a receiving unit 8!5, a signal processing unit 6, and an alarm unit 7, and various information from the sensor 2 is transmitted from the terminal transmission 1913, received by the receiver 5, Process the signal and notify the results. The sensor 2 is a mechanical switch 8 as shown in FIG. 2, and when the mechanical switch 8 is pressed by a person, an alarm is issued from the terminal transmitter 1f13. The terminal transmitter 3 includes a CPU 9, a modulation circuit 10, and a high frequency amplification circuit 1.
1. Zero body temperature sensor 13 composed of antenna 12, etc.
, pulse sensor 14, blood pressure sensor 15, etc. are other examples of the sensor 2, which detect the body temperature, pulse, blood pressure, etc. of the terminal operator. Good too. The mechanical switch 8 is off, and the input to the CPU 9 is normally H due to pull-up, but when the mechanical switch 8 is pressed, it becomes L, which is determined by the CPU 9 and the mechanical switch 8 is pressed by a wireless signal. This information is transmitted to the receiving section 4. This mechanical switch 8 is arranged at a distance T as shown in FIG. 3(a). - Periodic alarms are issued by pressing periodically at T2. The receiving section 4 has a timer function, which measures the time until the next alarm is issued within a predetermined periodic alarm time T1 to T2 after receiving the last regular alarm, and when the timer receives the third alarm, the timer
It is reset by a reset signal as shown in Figure (b), and the time until the next alarm is issued is similarly measured. If there is no next alarm after time T2 has elapsed since the last regular alarm, the third periodic alarm will be sent.
The alarm 7 operates as shown in FIG. 7(e). FIG. 4 is a block circuit diagram of a terminal device 1 according to another embodiment of the present invention, in which a timer 16 is provided in the CPU 9 and a terminal notification device 17 is provided.
It is designed to notify you when it is time to issue a warning using sounds, lights, vibrations, and other stimuli. It is assumed that the periodic alarm is issued between T and T2 after the last periodic alarm, and when the mechanical switch 8 is operated as shown in FIG. 0w and 5 which are alarmed as shown in b) Figure (C) is an alarm that is triggered intermittently between T1 and T2, and Figure 5 (d) is an alarm that is triggered continuously between T1 and T2. 5(b) to (d). Fig. 6 is a time chart of another embodiment of the present invention, which is designed to notify the time elapsed since a person arrived during the period when regular alarms should be issued. After operating 8, the system will issue an alarm intermittently from the time T1 has elapsed until T2, and the time interval will be gradually shortened as the time W1 elapses to notify the time progress. I never forget to report it. Fig. 17 shows the display on the display, and after operating the mechanical switch 8 as shown in Fig. 7(a), the display 18 as shown in Fig. 7(b) starts from the display time t after the time opening T1 has elapsed. This is how it is displayed.

【Effect of the invention】

Since the present invention is configured as described above, it is possible to periodically check the level of consciousness of the worker when working in an environment that is dangerous to life, and the periodic alarm time can be notified to the worker from the terminal. This has the effect of preventing a delay in the periodic alarm time, and also informing the worker of the elapsed time since the periodic alarm was issued, and ensuring that the worker can operate the sensor at the periodic alarm time. be.
