Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for detecting intrusion of a mouse into a detection range while distinguishing it from the passage of a person.

[0002]

2. Description of the Related Art Conventionally, photoelectric or infrared type sensors have been used for detecting mice. However, when the mouse reciprocates the detection position of the sensor with these sensors, the mouse may detect the mouse more than once for each mouse, and thus the detection data tends to be larger than the number of mice. Further, in the conventional device, not only the invasion of a mouse but also the passage of a person is detected at the same time, so that the detection data is considerably low. Therefore, accurate mouse detection means is desired.

[0003]

OBJECTS OF THE INVENTION It is therefore an object of the present invention to avoid overlapping counting of a mouse as much as possible and to distinguish the detection of mice from the detection of humans.

[0004]

In view of the above object, the present invention provides a mouse sensor, which is provided at a height of a mouse activity range, detects a mouse intrusion into the mouse activity range, and generates a mouse detection signal. A mouse pulse generation circuit that generates a mouse pulse signal with a mouse detection signal as an input, and the timer time while invalidating the mouse pulse signal generated during this time for a predetermined timer time from the time when the mouse pulse signal is input. A timer for mouse detection that generates a timer output after the passage of, a person sensor that detects the passage of a person directed to the activity range of a person and generates a person detection signal, and a person pulse signal with the person detection signal as an input And a human pulse generation circuit that generates a human pulse generation circuit during the predetermined timer time from the time when the human pulse generation signal is input. A timer for detecting a person who disables the operation of the mouse for detecting the mouse by a timer output for a predetermined timer time, a counter for integrating the timer output from the timer for detecting the mouse, and the above A mouse and a power supply circuit that supply necessary electric power to the portion form a mouse detection device.

The mouse for detecting a mouse invalidates a mouse pulse signal when it receives a mouse pulse signal during the generation of the timer signal. Therefore, the mouse detects the reciprocating motion of the mouse in the mouse detecting range. , The same mouse is less likely to be counted more than once. If two or more mice enter the detection range at the same time, the number of mice will be counted as one at that time, but in practice, such a situation rarely exists, so the mouse is more reliable than the conventional one. Will improve. Also, when a person passes the front of the mouse sensor, the mouse sensor operates, but at the same time, the human sensor also operates, and the timer for detecting the person operating by this prohibits the timer for detecting the mouse from operating. Therefore, the passage of a person is not mistakenly counted as a mouse intrusion, and the reliability of the mouse counting data is improved.

1 and 2 show the appearance of a mouse detection device 1. The mouse detection device 1 is assembled by a suitable case 2, and a mouse sensor 3, a power switch 4, a counter indicator 5, and a human sensor at a position higher than the mouse sensor 3 are mounted on the front surface thereof at a height of a mouse detection range. 6
In addition, the detection operation display lamps 7 and 8 and the battery voltage reduction display lamp 9 are attached. Also,
The output terminal 10 is attached to one side surface, and the battery case 11 is incorporated on the back side. The mouse sensor 3 is, for example, an infrared sensor, and is attached so as to retract backward from the front opening of the cylindrical holder to narrow down the mouse detection range.

Next, FIG. 3 shows an electric circuit of the mouse detection device 1. The mouse sensor 3 is connected to the input side of a mouse 14 for detecting a mouse and the lamp 7 by a mouse pulse generator 12. Also, this timer 1
4 is, for example, an infrared sensor, and a counter 15 is provided on the output side.
And relay 16 are connected. Further, the human sensor 6 is connected to an input side of a human detection timer 18 and a lamp 8 via a human pulse generator 13. On the output side, the timer 18 is connected to the mouse 14 for detecting the mouse. A battery 19 inside the battery case 11 is connected to a power supply circuit 20, and the power supply circuit 20 is connected to each of the above-mentioned operating parts via a display lamp 9 and an operating time zone setting device 21. .

Next, FIG. 4 shows three operation modes ABC of the mouse detection device 1. First, the operator operates the setting device 21, sets an operating time period, for example, a time period from 18:00 on the current day to 8:00 on the next day, and turns on the power switch 4. As a result, the mouse detection device 1
It is set to operate automatically in the set operation time zone.

In operation mode A, a mouse detection signal is generated when the mouse sensor 3 detects a mouse that has entered the detection range. Therefore, the mouse pulse generator 12 outputs a mouse pulse signal having an appropriate pulse width. , With this, the lamp 7 is turned on, and a mouse 1 for detecting a mouse is displayed.
4 is operated. The timer 14 invalidates the mouse pulse signal newly generated during this timer time T from the time of inputting the mouse pulse signal over a predetermined timer time T, and after the timer time T elapses,
Generates timer output, counter 15 and relay 16
Send to. The counter 15 counts the timer output to integrate the number and displays the integrated value on the counter display 5. In this way, when the mouse 14 for detecting a mouse generates a timer signal for a predetermined timer time T, the mouse pulse signal from the mouse sensor 3 becomes invalid, so that the same mouse is counted twice. Almost never happen. Further, the relay 16 receives the timer output as an input and is turned on to operate an external device such as a mouse trap or a mouse for photographing a mouse. In addition, the display contents are the reset switch 17
Can be erased to zero.

When the human sensor 6 detects the passage of a person within the detection range, a human detection signal is generated and sent to the human pulse generator 13. Here, the human pulse generator 13 outputs a human pulse signal having a predetermined pulse width to instantly turn on the lamp 7 and operate a timer 18 for human detection. Here, the timer 18 generates a timer signal for a predetermined timer time t from the time of inputting the human pulse signal, and invalidates the human pulse signal newly generated during the timer time t, The timer signal is sent to the mouse 14 for mouse detection to prohibit the timer operation.

Therefore, as in the operation mode B, even if the mouse sensor 3 detects a mouse within the timer time t, the mouse 14 for detecting a mouse does not operate.
In this way, the timer signal of the timer 18 becomes the timer 14
Since the mouse pulse signal is disabled during this period, the timer 14 is set to the inactive state.

Further, as shown in the operation mode C, when the human sensor 6 detects a person while the mouse detecting timer 14 is operating, the human detecting timer 18 is
By the timer signal, the operation of the timer 14 is prohibited at that time, and the timer operation is stopped. Therefore, the passage of a person is not detected as a mouse. The timer times T and t can both be adjusted and can be set appropriately within the range of 10 to 60 seconds.

[0013]

Other Embodiments In the above embodiment, the human sensor 6, the human pulse generator 13, and the human detection timer 18 are provided in order to distinguish between the entry of a mouse and the passage of a human. When the mouse detection device 1 is used in a place where it does not pass, that part can be omitted.

[0014]

According to the present invention, even if the same mouse reciprocates within the detection range for a predetermined timer time, it is less likely to be erroneously counted twice or more. Therefore, the reliability of the mouse detection data is improved. Moreover, since mouse invasion and human passage are identified and only mouse intrusion is counted, the reliability of mouse detection in a detection range in which mouse intrusion and human passage can occur at the same time is improved.
