Description

  The present invention relates to a power supply control system used when various electric devices such as a television, a refrigerator, an air conditioner, and a laundry device are used at a fixed charge, and more particularly, to a power supply control system that inserts a key and energizes the electric device. Is.

  Televisions, refrigerators, laundry equipment, etc. that are installed and used in hospitals, hotels, etc. are generally charged (time rental) with a timer attached.

  In this method, when using a television or the like, a prepaid card that records the number of times of use corresponding to the amount paid in advance is issued to the user, and this prepaid card is inserted into a timer attached to the TV. It becomes possible to view by doing. Then, the current detection circuit mounted on the timer detects the presence or absence of current consumption, performs calculation processing according to the usage time, performs frequency subtraction according to the set subtraction rate, and time according to the available frequency Only being able to watch TV.

  Specifically, after connecting the card timer to the TV power line and turning on the power, the number of available times is reduced according to the available time based on the charge rate, and the total available number of times recorded on the prepaid card is When there is no more power, it is controlled so that power is cut off and power is not supplied to the television.

  A timer system using such a prepaid card is used, for example, to charge for the usage time of a television in a hospital room (see Patent Document 1). Patent Document 2 starts a test program for confirming the operation of a control board on which a control circuit for energization control is formed on an auxiliary card using a main card on which money data is recorded and an auxiliary card. A configuration in which inspection start data is stored is disclosed. It also has microcomputer judgment means that can calculate the frequency of the data read by the card reader / writer in units of time, rewrite the data by addition / subtraction, and check the presence / absence of the card or the presence / absence of the usage frequency. Deployed a control board that operates electric devices such as TVs, refrigerators, coolers, etc. only when available by means, sends a signal to the timer controller when it is functioned, and performs arithmetic processing inside the timer according to the usage time Have been disclosed (see Patent Document 3).

  By the way, in the timer system as described above, there is a problem that a timer device arranged in parallel with an electric device and a dedicated device for adding or replenishing the available frequency to the prepaid card are required, and the initial investment of the facilities is increased. In recent years, a method has been adopted in which usage fees for electrical equipment are covered by accommodation and hospitalization fees so that the usage time is not limited. However, since usage fees are collected, it is unequal to those who use electrical equipment, which causes troubles during the settlement of usage fees.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a power supply control system that can be manufactured and operated at low cost, and that can use an electric device with a fixed amount and simple operation. .

  For this reason, the power supply control system according to the present invention is configured such that the key is inserted, the cylinder lock that switches between the first lock position and the second lock position, and the connection connector at the first lock position is energized, An electrical device control board that turns off the power to the connector at the lock position 2; a power plug that is connected to the electrical equipment control board and inputs a commercial power supply; and a commercial power source that is connected to the electrical equipment control board to the electrical equipment. The first feature is that a connection connector for energization is provided.

  In addition, the cylinder lock and the electric device control board are provided with a plurality of the connection connectors, wherein the electric device to be energized is switched every time the key is switched to the first lock position. A third feature is that a spark killer is connected between them.

  Furthermore, a card reader that reads a key information from the storage medium in which a storage medium in which predetermined key information is recorded is inserted, a display unit that is turned on when power is supplied to the electrical device, and a display unit Display unit control means capable of turning on or off the display, display unit detection means for detecting the state of the display unit, and electric power for determining an electric device to which power is supplied from the state of the display unit detected by the display unit detection unit A fourth feature is that a supply determination unit is provided, and a predetermined electrical device is energized depending on the lighting state of the display unit each time the storage medium is inserted into the card reader.

The power supply control system of the present invention has the following excellent effects.
(1) Since a timer circuit is not required, manufacturing costs can be reduced. Further, the size can be reduced, and the installation space can be omitted.
(2) Since an exclusive device or the like for adding or supplementing the usable frequency is unnecessary, the initial investment of the system can be suppressed.
(3) Since the number of keys or storage media to be used as a master key can be specified, the operating cost can be reduced.
(4) Since the electric device is configured to operate depending on the state of the display unit, the energized electric device is easily visible and highly convenient.
(5) Since energization is performed by performing an unlocking operation with a key or a storage medium, only a person who desires to use an electric device can use it.
(6) Since the spark killer is provided between the cylinder lock and the electric equipment control board, it is possible to suppress overvoltage generated due to the key OFF operation.
