Description

Device for control seat temperature < RTI ID = 0.0 >

The present invention relates to a seat temperature control apparatus, and more particularly, to a seat temperature control apparatus that can automatically prevent a sheet from being stolen and stolen by automatically adjusting the temperature of a seat including a chair for a seat, And more particularly, to a seat temperature control apparatus which can maximize the efficiency of maintenance by realizing automatic detection of a failure position in the event of a failure.

A seat, which is installed in an outdoor place, for example, a bus stop or a train station, and is especially known as a chair which is installed outdoors especially for the convenience of passengers waiting for riding, It is used for various purposes such as reading.

However, the seat of a chair or the like installed outdoors is maintained in a cold state due to a decrease in the atmospheric temperature in the winter, so that when a passenger or a user who is sitting on the seat feels a cold feeling, .

In order to solve this problem, efforts have been made to increase the convenience of users by heating the sheet while heating the sheet in accordance with a predetermined temperature band through a temperature sensor or a bimetal.

However, when a heater installed in a very large number of sheets fails, there is no way to confirm it, so that the maintenance is very difficult. If the heater is broken, it becomes a unfamiliar device, and there is no utility.

In particular, when the temperature sensor or the bimetal is broken, the power can not be cut off, and there is a risk of overheating or a fire. In addition, there is a disadvantage that waste of electric power is wasted because power cutoff control is not performed.

However, it is not appropriate to place and manage the management personnel on a regular basis, because it causes wasted cost and wasted manpower.

Of course, in the case of a seat including a chair installed indoors, the same similar problem may be encountered when temperature control is required.

However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

The seat temperature control apparatus according to the present invention realizes a double locking function so that the control housing can not be arbitrarily opened. Also, it is possible to perform double detection control for prevention of overheating as well as for theft prevention. Not only achieves convenience of the maintenance and cost reduction but also has a useful feature including a power saving function by automatically turning off at the early morning hours when there is no user.

To this end, the seat temperature control apparatus according to the present invention preferably includes a rectangular box-shaped control housing 100 as shown in FIGS. 1 and 2, and is preferably installed and fixed on a seat bottom of a chair or the like installed outdoors.

Of course, the control housing 100 may be mounted on a structure or the like around the seat, but the most preferable position is the bottom of the seat.

In this case, when the control housing 100 is detached from the mounting position using a limit switch or a proximity sensor, an alarm sound may be automatically generated to prevent theft. To this end, the control housing 100 An alarm means may be incorporated.

The control housing 100 includes a box-shaped main body 110 having an opened upper portion and a cover body 120 for hingingly opening and closing the opened upper portion of the main body 110.

At this time, a main board MB is mounted on an inner bottom surface of the main body 110, and a sub board SB is mounted on the cover body 120, both of which are connected by a connector CT.

In addition, a plurality of wiring guides G1, G2 and G3 are provided on one side of the main body 110, one of which is a wiring guide for drawing out a power line for connecting to the main board MB, One is a wiring guide for connecting the GPS antenna to the main board MB and the other is a wiring guide for connecting the temperature sensor line TL and the heater control line HL to each other.

A latch type locker 132 is provided on one side of the main body 110 and a locking piece 134 is fixed to the corresponding side of the cover body 120 to be mutually lockable, Respectively.

In particular, in the present invention, the signal processing of the control signal is performed by the RS232 communication method, so that stable driving can be performed and accurate control can be maintained.

2 and 4, a solenoid 140 is installed on one side of the main body 110, and a solenoid locker 142 is provided on the solenoid 140. When the solenoid locker 142 is energized, The solenoid 140 is configured to be fixed or released in the fixing groove 146 of the locker stator 144 provided at the corresponding position of the cover body 120 and to be released from the fixation. And a secondary locking structure is realized by implementing a control method based on the password setting for double locking.

3, the main board MB is provided with a main control unit 310, which is a main control unit commonly referred to as a 'microcomputer', and the MCU 310 is provided with an external temperature detector 320 The internal temperature detector 330, the heater controller 340, the A / D converter 350, the GPS controller 360, and the time controller 370 are connected and controlled.

In this case, the external temperature detector 320 and the internal temperature detector 330 are a type of temperature sensor. The external temperature detector 320 is a means for detecting an ambient temperature outside the seat. Is a means for detecting temperature.

In addition, the heater controller 340 may be configured to control the FET controller in a constant current mode, for example, to improve the circuit stability while preventing the occurrence of fire.

Particularly, when the AC power source is used, it is preferable to use DC 24V through the A / D converter 350 as a power source since the control stability as well as the danger of electric shock is deteriorated.

Accordingly, if the ambient temperature is detected as 10 ° C and the detected temperature inside the seat is less than 10 ° C, the heater control unit 340 activates the heater in accordance with the control signal of the MCU 310, If it exceeds a certain temperature (eg set temperature), it can be operated to turn off the heater.

Of course, the reference of the atmospheric temperature for heater operation can also be set. This can be set to be used only during the winter season and to be turned off during the summer season, which will be described later.

For example, the operation reference temperature may be set to 5 ° C, and the temperature to be turned off may be set to 20 ° C. If this is set, the heater automatically turns on and off according to whether the temperature is exceeded.

Here, if the sensor fails, such control becomes difficult. In order to solve this problem, in the present invention, since the heater controller 340 controls the constant current control method, the wiring temperature rises due to the continuous heat generation of the heater when the sensor fails. In other words, the current value greatly increases. When such a phenomenon occurs, the circuit is cut off from the main board MB under the control of the MCU 310 to cut off the current supplied to the heater, thereby forcibly turning off the heater .

At the same time, when the heater is forcibly disconnected, it is transmitted to a management server (not shown) provided in the remote control room, and it is more preferable that the maintenance is performed promptly by informing the failure in real time.

To this end, a unique control number is assigned to each control housing 100 in the MCU 310. When an error occurs, the MCU 310 communicates with the management server through a wireless communication unit 430, which will be described later, The unique control number of the control housing 100 and the coordinate information (position information) received from the GPS controller 360 are transmitted together to the management server.

In this case, the management server can promptly determine where the control housing 100 is located, so that the control server 100 can respond promptly.

In addition, since the time controller 370 has a standard time for each country, when the power is turned on after installation, it is ascertained from the coordinate information received from the GPS controller 360, and is automatically adjusted according to the standard time of the corresponding country, . This can be done by country-specific code verification.

In particular, it is operated under the control of the MCU 310 so as to automatically turn off the heater at the early morning hours when there is little human activity in accordance with the standard time of the country.

As a result, unnecessary power dissipation can be prevented and efficient drive management can be achieved.

In addition, although not shown, a fuse is built in, and when the heater is driven, the fuse is automatically cut off when an excessive current flows, thereby physically preventing the heater driving power.

Meanwhile, the cover body 120 is provided with a display 450 and a keypad 420.

At this time, the display 450 is a kind of output unit which not only displays the set values at the time of setting the function and temperature, but also displays the fluctuations of the current values required for operation at the time of operating the heater in real time to ensure ease of management Lt; / RTI >

The keypad 420 is used as a kind of input unit for setting functions and temperature as well as setting a password.

The sub board SB mounted on the cover 120 includes a sub control unit (SCU) 410, which is a sub control unit.

In addition, the SCU 410 is designed to be connected to the keypad 420 in a controlled manner to control the display 450, and further includes a wireless communication unit 430 and a locking controller 440.

At this time, the wireless communication unit 430 maintains a real-time communication state with a management server (not shown) of the remote location management room so that a quick response can be made in the event of a failure.

Of course, the communication method for management is GPS, but there is also a system of information information system installed in the bus or train station platform, that is, a system (mainly a display) for notifying when a bus or a train arrives, IP address, and address value, it is possible to know where it is installed. Therefore, it is possible to use this data to transfer the data to the management server of the remote management room so as to quickly check the malfunction or non-malfunction, and various other methods may be applied will be.

The locking controller 440 is a controller for controlling the driving of the solenoid 140 according to whether or not the key is locked when the password is set. That is, if the password is incorrect five times in succession, the SCU 410 The keypad 420 may be turned off for about 30 seconds so that the password can not be pressed.

In addition, when the cover body 120 is forcibly opened in the state that the password is not released, that is, when the cover body 120 is forcibly opened, an alarm is automatically generated to warn the unauthorized person, It is more preferable to prevent the endless cutting.

In this manner, by including the password and the locking structure using the solenoid 140, double lock is possible together with the latch lock which is the basic lock.

However, in order to solve the problem occurring in the initial assembly, the present invention uses the locking ring 500 as shown in FIG.

That is, when the solenoid locker 142 is inserted and locked in the fixing groove 146 of the locker stator 144 during initial assembly, it is impossible to open the solenoid locker 142 unless power is supplied, so that it is confirmed that the power supply is stably supplied A means is required to be able to open easily.

To this end, in the present invention, even if the latching type locker 132 is closed by closing the cover body 120 by fixing the locking chamber 500 to the locker stator 144 to close the fixing groove 146, the solenoid locker 142 Is not protruded due to the locking cradle 500 and is held in a state where it is not pushed into the fixing groove 146, so that the power supply is poor or a final confirmation process such as password setting and confirmation opening after initial driving is performed It should be easy to open until rough.

Of course, when the setting is completed, the bolt is loosened and the locking chamber 500 is separated and removed to realize the double locking function.

As described above, since the present invention is capable of real-time management, it is easy and convenient to maintain, and the installation position of each control housing 100 can be grasped so that quick measures can be taken and a fire caused by overheating can be prevented Respectively.
