BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device suitability discrimination apparatus for a remote control installed in a central processing unit (CPU), a nonvolatile memory, and an input / output unit in one semi-custom LSI logic circuit element for forming a microcomputer.

In the field of mass production of consumer products such as various electric appliances and gas appliances, the control of the apparatus is performed by a remote controller having a control circuit using a microcomputer.

In the control circuits of these remote controllers, the number of parts for configuring the control circuits is as small as possible, and at the same time, a logic circuit element having a certain basic arithmetic function and a program designed by a user are designed to reduce the failure rate as a device. Single-chip microcomputers, such as LSIs input into memory, are used more frequently than microprocessors.

In the control circuit of such a remote controller, since a necessary control function can be obtained by one single-chip microcomputer, normally only one non-LSI is actually provided as a microcomputer.

Such a logic LSI corresponds to each device (e.g., an electric device and a gas device, etc.), and the configuration of the package, the shape of the operating power, etc., in which the program specifications are different from each other and the logical LSIs are drawn, are the same. Often the same.

For this reason, device names and symbols for indicating that the specifications are different are written on the back of the package, and in the case of devices having different control circuits and control contents, the devices suitable for controlling the respective devices are actually installed. .

In the remote controller for controlling a device actually equipped with such a logic LSI in the control circuit, if there is a change in the specification of the main body of the device, the circuit configuration of the control circuit and the specification of the program change accordingly.

By the way, even if a code or symbol indicating the type of equipment to be manufactured is recorded in the logic LSI to be actually installed in the control circuit of the remote controller, in the case of a small change such as a specification change, the model name or symbol for displaying the type of equipment is indicated. The simple signs to be displayed are not greatly changed, and there are cases in which a matter of specification change is simply added or a case in which a matter of specification change is not recorded reliably.

In such a case, if the correct logic LSI according to the device or model is not actually installed in the control circuit of the remote controller, when a basic configuration such as package shape and pin arrangement uses the same logic LSI, no major failure occurs. At first glance, there are things that do normal work.

In this case, there is a problem that the user finds an abnormality after actually operating the device through the remote control under various operating conditions and operating conditions.

Therefore, there is a possibility that a remote controller controlling a given device cannot be shipped in a complete state.

The present invention provides a remote control device for easily determining that a logic LSI to be actually installed is suitable for a remote control control circuit of a predetermined device in a control circuit of a remote control device for controlling various devices such as an electric device and a gas device equipped with a microcomputer.

The programmable logic circuit element is suitable for the device only through the self-diagnosis unit. Can only technically control the device, if suitable for Make it sweet.

In the present invention, when the programmable logic circuit element is actually installed in the control circuit of the remote controller, the device information generation circuit is connected to at least one of the input ports.

When the control circuit is operated by a program, the self-diagnosis unit in the programmable logic circuit element determines whether or not it is suitable for a predetermined device based on the discrimination information and device information stored in the nonvolatile memory means. For example, gas appliances), and if not suitable, the appliances are not controlled.

In the present invention, the device is controlled by the remote control only when the programmable logic circuit element installed in the predetermined remote control is suitable for the device, and the device is not controlled when it is not suitable.

Therefore, when the programmable logic device is actually installed in the control circuit of the remote controller, the programmable logic device can be quickly determined whether or not it is suitable for the device. It is possible to easily find out whether or not the remote control is a real device, so that the device and the remote control for controlling the device can be shipped in a complete state.

In addition, the main remote control 10 is mainly fixed to a place that can be easily adjusted by the assistant, such as a kitchen, the bathroom remote control 20 is fixed mainly to a place that requires preferential operation for other places, such as in the bathroom. Each of the remote controllers 10 and 20 is connected in parallel with each other by two wires between the control device 2 of the gas water bath system 1 and transmits signals between the control device 2 and the control device 2. The operation state of the gas hot water bath system 1 is set, the content thereof is displayed, and the operation content corresponding to the operation state is displayed.

It consists of a plurality of switches for giving a necessary signal such as an indicator lamp, and is connected to the semi-custom LSIs 30 and 40 via the matrix circuit, respectively.

The switch group 21 of the bathroom remote control 20 is provided with a priority switch for performing priority operation again in addition to each switch of the switch group 11.

The display circuits 12 and 22 are circuits for displaying, on the liquid crystal display, a set state such as a set temperature and an operating state.

The device information generation circuits 13 and 23 are circuits for generating model information, such as whether the remote controller 10 or 20 is the main remote control 10 or the bathroom remote control 20 of a hot water supply system. Device information generation circuits (13) and (23), respectively, according to the type, the specification of the main / bathroom of the remote controller, the specifications accompanying the system improvement, etc., and outputting the 4-bit model data already stored in the internal storage unit. Is connected to the ports of the semi-custom LSIs 30 and 40, respectively.

The communication interface 14, 24 converts the parallel bit setting data created based on the operation signals of the switch groups 11 and 21 of each remote control into the serial bit communication data, and sends out the control. Are transmitted to the device 2 and the other remote control.

When the serial bit communication data is received by the other remote controller, it is converted into data for setting the parallel bit, thereby changing the display contents of the display circuit.

Semi-custom LSI (30), (40) is a logic semi-tubular LSI configured as a programmable logic circuit element, the central processing unit (CPU) 31, (41), memory 32, (42), input and output unit 33 ) And (43) as main components, and a single chip microcomputer having a system control unit clock generation unit for the semi-custom LSIs 30 and 40 in the other.

The central processing units 31 and 41 are central parts of the microcomputer, and perform the necessary control as the remote controller by performing logical operation in accordance with the programs in the memory 32 and 42.

At this time, the central processing unit 31, 41 is provided with a self-diagnostic unit 311, 411, LSI (30), (40) according to the model signal of the device information generation circuit (13), (23) ) Is actually installed in the predetermined remote control.

That is, the central processing unit determines whether the semi-custom LSIs 30 and 40 built in each of the remote controllers 10 and 20 correspond to the model data stored in the device information generation circuits 13 and 23. The self-diagnostic parts 311 and 411 in (31) and (41) determine that the gas hot water bath system 1 is not controlled by the remote controller if it is not suitable.

The memory 32 and 42 are a ROM as a nonvolatile memory, and a RAM and a register for temporarily storing data necessary for logical operation. In the ROM, a system for performing necessary control as a remote controller as in the second diagram is provided. The programs 32a and 42a and the control data 32b and 42b are stored. In particular, in this embodiment, the LSI 30 is stored in the ROM in accordance with the model signals of the device information generation circuits 13 and 23. Are stored in the device information generation circuits 13 and 23 when operating as a remote controller. The self-diagnostic section 311 in the central processing units 31 and 41 to read out the model data and whether it is bonded to the discrimination data 32C and 42C of the semi-custom LSI 30 or 40, respectively. , At 411, and if it is not And is not to stop the action of each of the remote control to function as a control panel of the control device (2).

The input / output units 33 and 43 have a plurality of sets of input ports, output latches and output ports, and an A / D changer, a D / A converter, or an analog interface. The switch groups 11, 21, Signal or data between the circuits of the display circuits 12, 22, the device information generation circuits 13, 23, the communication interfaces 14, 24, and the central processing units 31, 41. Replace it.

Here, one set of input ports is connected to the device information generation circuits 13 and 23, and 4-bit model data is transmitted and read as required by the central processing units 31 and 41.

In the semi-custom LSIs 30 and 40, when there is a setting change by the switch groups 11 and 21, the setting state is displayed on the display circuits 12 and 22, and the setting signal is displayed. In accordance with this, the setting data for the control device 2 is created, converted into communication data at the communication interfaces 14 and 24, and transmitted to the control device 2.

When the setting contents are changed by the other remote controller, the communication data is received and the new setting contents are displayed on the display circuit.

In each remote controller having the above configuration, each semi-custom LSI is usually housed in a ceramic package having a plurality of pins or the like, and is actually mounted on or controlled by a socket fixed to the control panel of each remote controller. There is a case where it is actually mounted directly on a board | substrate.

If each semi-custom LSI is actually mounted on a remote controller suitable for controlling a given device at the time of manufacture at the factory, each remote controller is properly operated in the inspection step.

On the contrary, if the semi-custom LSI is actually installed in a remote control device for which other devices are not inadvertently fitted, the operation test in the factory may stop the operation of the semi-custom LSI actually installed in the unsuitable remote control.

For example, since no display is performed on the display circuit and no signal from the switch group is received, the remote controller can be easily found to be defective.

Alternatively, the system program may cause some display to appear on the display circuit. In this case, even if a signal from the switch group is operated, no signal is accepted, so the display content of the display circuit does not change or is controlled. Inappropriateness such that the operation of the gas water bath system 1 by the device 2 does not start immediately appears, so that a remote controller is easily defective because a semi-custom LSI having different model information is mounted on a predetermined remote controller. I can find it.

Therefore, it is conceivable that an inadequate semi-custom LSI is actually installed as one of the causes of the failure of the remote controller, and it is possible to prevent the remote controller from being shipped in an incomplete state.

As described above, the present invention is in the step of investigating whether the remote control is defective when the wrong logic LSI is actually installed in the control circuit of the remote controller which is actually equipped with a logical LSI which is different in control contents and data but cannot be distinguished at first glance. Since it can be found easily, it is possible to prevent the failure of the equipment due to the malfunction of the remote control.

When there is a specification change accompanying improvement of the gas water bath system, the semi-custom LSI whose control contents, such as the system program, are changed at that time is used, but in this case, the function display of each semi-comic LSI is unclear. Also, different types of data and discrimination data can be found to be inadequate easily in the inspection step.

Therefore, there is no shipment of the remote controller for controlling various devices in the incomplete state.
