The technology described in these patent documents determines whether or not the allowable power is exceeded when the plug is inserted, and various medical devices are connected to the power strip in facilities such as the intensive care unit of a hospital. If it is used in an urgent and busy manner, the risk of connecting additional connection plugs that exceed the allowable current value set for the power strip cannot be resolved.

In view of this point, the present invention detects the insertion information of the connection plug immediately before inserting the connection plug to determine whether or not the allowable power is exceeded, and various medical devices in facilities such as the intensive care unit of a hospital. When used by connecting to a power strip, there is no risk of additional connection plugs being connected beyond the allowable current value set for the power strip, even in times of emergency and extreme busyness. That is the issue.

Each outlet has multiple outlets, each outlet has a power consumption warning system that allows devices to be connected, and each outlet has a power strip with a maximum permissible power value or multiple individual outlets. It is equipped with a power consumption warning system to which the device can be connected, and provides a power strip or power strip with a maximum allowable power consumption.

The table tap or power tap is configured as follows.

A predetermined device is connected to a plurality of outlets or some of the outlets, and a connection plug having a tag tag having a chip with built-in reading information can be connected to the other outlets or outlets.

The RFID tag records the set power consumption to be used in the device connected to the connection plug.

The tag having the reading information built-in chip is a tag having an RFID chip. Alternatively, the tag having the reading information built-in chip is a tag having a QR code.

When the tag having the reading information built-in chip is the tag having the RFID chip, the information recorded on the RFID chip is read by the reader.

RFID tags with RFID chips are represented by μ-chip (registered trademark) of Hitachi, Ltd. A 128-bit ID number is written on the mu chip. An RFID communication system having this mu chip can be used. An RFID communication system consists of an RFID tag and a reader (which may be a reader / writer) that reads the information. The mu chip has a built-in antenna, and the ID number can be transmitted to the reader in a non-contact manner using the received radio wave as the operating power with only a 0.4 mm square chip. Therefore, the mu chip can be easily embedded or mounted in a power strip, for example, a power strip. A power strip is known as a power strip for supplying power to a plurality of electric appliances at a place away from an outlet installed on a wall or the like.

A predetermined device is connected to the outlet or some of the outlets, and a connection plug having an RFID tag having an RFID chip can be connected to another outlet or the outlet, and the RFID tag is connected to the connection plug. The power to be used is set for the device to be used.

When a tag with a QR code is used as a tag with a chip with built-in reading information, a small camera is installed on the tap side, that is, the receiving side, and the tag with the QR code is photographed by the small camera and recorded in the QR code. To get. The built-in information may be read by using another readable chip or code.

The power consumption warning system is connected to the outlet or some of the outlets and acquires the cumulative power consumption that is the cumulative total of the power consumption or the power limit used by the device in use, and the connection plug is just before connection. Is detected, the set power consumption and the cumulative power consumption are calculated to obtain the estimated power consumption, and when the power consumption is larger than the maximum permissible power consumption, the power consumption warning information regarding the use of the device is displayed. Emit.

The electric power (W) can be read as an electric power value, an electric energy (Wh), or a current value. Moreover, the outlet port can be read as a plug insertion port.

In the conventional technology, the information on improper use of the device at the outlet or the outlet issued by the warning transmitter measures the accumulated power consumption after the outlet or the connection plug of the outlet is connected, that is, after it is plugged in. It is made by comparing with the set power consumption, and it is not suitable for use in an emergency and busy place such as an intensive care unit in a hospital.

In the present invention, information on improper use of the device at the outlet port emitted by the warning transmitter, that is, unusable information is sensed, that is, detected and accumulated use immediately before the connection plug of the outlet is connected, that is, immediately before being inserted. In places where the power is assumed and compared with the set power consumption, comparison information is obtained, the breaker of the distribution board does not shut off, and the facility such as the intensive care unit of a hospital is extremely busy. Suitable for use.

In this way, it is judged whether or not the allowable power is exceeded immediately before inserting the connection plug, and when various medical devices are connected to the table tap and used, for example, in the intensive care unit of a hospital, it is urgently busy. It is possible to prevent the risk of connecting additional connection plugs that exceed the allowable current value set for the power strip, even when it is extremely present.

The figure which shows the example which applied and developed the idea shown in FIG. 4 to a power strip 200. The block diagram of the intensive care unit of the hospital to which this invention was applied.

Hereinafter, examples of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an example of a table tap 100 to which the present invention is applied. An example in which the tag having the reading information built-in chip is a tag having the RFID chip will be described below, but the present invention is not limited to this example.

The table tap 100 is configured as a table tap with a warning. The table tap 100 has a plurality of outlets 2 in the table tap case 1 and, in the case of this embodiment, seven outlets 2 in parallel. A connection plug 3 is connected to each outlet, that is, it can be inserted. In the case of this embodiment, a state is shown in which four connection plugs are inserted into outlets, and one connection plug having the same structure is stand-by and is about to be connected to a blank outlet. In order to distinguish between the two, the former (the connection plug into which the connection plug is inserted is referred to as 3A, and the latter (the connection plug before insertion) is referred to as the connection plug 3B.

The table tap 100 is connected to a power supply having a power switch 4 on the front surface corresponding to each outlet, a cord 5 on the left end side surface, and a breaker (not shown) of a distribution board at the tip. It has a connection plug 11 to be connected.

The connection plugs 3A and 3B are connected to cords 6 to 10 respectively, and the cords 6 to 10 are connected to devices A to E, for example, a medical device, respectively.

One RFID tag 12 is adhered to and provided on the cord 10. The RFID tag 12 may be adhered to or internally attached to the surface of the connection plug 3B. The RFID tag 12 moves integrally with the connection plug 3B.

In the case of this example, the table tap 100 includes a power consumption warning system 101 for the power used by the table tap inside the table tap case 1. A start switch 21 is provided at the left end of the front surface of the table tap 100, and the start switch 21 activates the power consumption warning system 101.

In this example, the table tap 100 has a display unit 35 at the left end of the front surface in parallel with the start switch 21.

A power consumption warning system 101 is provided in the table tap case. The receiving unit 31, the power consumption calculation unit 32, the information processing unit 33, the warning transmitting unit 34, the display unit 35, and the display processing unit. It is installed inside the power strip case or mounted on the surface of the power strip case. A storage unit 37 may be provided. For example, the receiving unit 31, the power consumption calculation unit 32, the information processing unit 33, the warning transmitting unit 34, and the display processing unit 36 are arranged inside the table tap case 1, and the display unit 35 is mounted on the front surface. ..

FIG. 2 is a wiring diagram of the power consumption warning system 101 shown in FIG.

In FIG. 2, the table tap 100 has a CPU 102. The power consumption warning system 101 is formed with the CPU 102.

A signal line 47 for transmitting a current measurement value from the power supply line 45 and the current measuring device 46 is connected to the CPU 102. The current measuring device 46 may be provided for each outlet and the measured values of each current may be totaled as the power consumption.

It is important that the information on improper use of the device at the outlet, that is, the unusable information, issued by the warning transmitter is detected and acquired as the information immediately before the connection plug of the outlet is connected, that is, immediately before being inserted.

The CPU 102 is connected to the reader 41. The communication data from the reader 41 is taken in. The reader 41 constitutes the above-mentioned receiving unit 31 and is arranged inside the table tap case 1. It may be mounted on the surface of the table tap case 1. Wireless communication 42 can be performed with the RFID tag 12. It is known that the reader 41 and the RFID tag 12 can obtain a communication distance of 50 cm to 1 m for the 13.56 MHz band RFID system, 2 to 3 m for the 2.45 MHz band RFID system, and 3 to 5 m for the 950 MHz band RFID system. Be done. It is better to avoid using a proximity type with a communication distance of about several centimeters because the margin of insertion time of the connection plug 3B is reduced. A communication distance of 40 cm to 1 m, preferably 40 cm to 50 cm is selected by appropriately selecting the MHz band. It takes hundreds of ms to acquire information from an RFID tag, and it takes less than a second including calculation and alarm display. If it is 40 cm to 50 cm, it will not be inserted by mistake if the distance from the occurrence of the alarm to the insertion of the connection plug into the outlet or the outlet is 40 cm to 50 cm.

Also, if it can be detected at a distance of about 1 m, there are multiple table taps and power taps. For example, if they are arranged at intervals of 50 cm, do you bring the device you want to connect near the table tap or power tap? Even if you don't have it, it's easy to check which table tap you can connect to and which table tap you can't connect to. Make it possible to respond at a distance that matches the usage environment.

An RFID system having such a MHz band is suitable for detecting that the connection plug is about to be connected.

The maximum allowable power to be used is set in the area where the breaker of the distribution board does not cut off the table tap 100.

A connection plug connected to a predetermined device is connected to some of the plurality of outlets, and a connection plug having an RFID tag having an RFID chip can be connected to the other remaining outlets.
The RFID tag stores the set power consumption of the device E connected to the connection plug 3B. In most cases, the rated power consumption is used as the set power consumption, but the maximum power consumption among the power consumptions used in the past can be used.

The reader 41 senses that the connection plug 3B, that is, the RFID tag 12 is approaching. As a result, the set power consumption stored in the RFID tag is received. The set power consumption can be the planned power consumption.
