Description

[Detailed description of the invention] The present invention is a home control system in which a receiver and a transmitter are connected by weak radio waves, for example.
The present invention relates to a transmitter used in a security system and the like, and particularly relates to the structure of a transmitter that includes a battery storage section provided with a lid in the main body, stores a battery in the storage section, and transmits data using the battery as a power source.

The technical background and conventional examples will be described below using a transmitter used in a home control system as an example.

Generally, in a home control system, as shown in Fig. 1, a plurality of transmitters 1, 1,
Even if the receivers 2 are installed in multiple homes 3, 3..., the signals transmitted from each transmitter 1 will not cause false alarms or malfunctions on the receiver 2 side. A house code is set for the transmitted signal. Also, even within the same household,
When multiple transmitters 1, 1... are installed, a unit code is set in the transmission signal from each transmitter 1 in order for the receiver 2 to identify which transmitter 1 is detecting an abnormality. There is.

FIG. 2 shows an example of the code of the transmission signal transmitted from the transmitter 1. Signal code A is house code B for identifying each home where a home control system is installed, and unit code C is for identifying each transmitter installed within the same home.
and a status code D indicating the status of the sensor attached to each transmitter. This code is composed of a combination of electrical signals of "0" or "1", and among the above signal codes A, the house code B and the unit code code C are set by turning on the code setting switch provided on each transmitter. Or set by turning OFF.

By the way, the conventional transmitter used in, for example, the home control system mentioned above had a configuration as shown in FIG. In Figure 3, 4
1 is a transmitter main body, and this transmitter main body 4 is box-shaped and includes an upper cabinet 5 and a lower cabinet 6. 7 is a board attached to the upper cabinet 5, and 8 is a board attached to the lower cabinet 6. Each of the boards 7, 8 is connected with a plurality of lead wires 9, 9, . . . . Reference numeral 10 denotes jumper wires with insulators for setting transmission signal codes, which are provided in a plurality on the board 8 attached to the lower cabinet 6, and the jumper wires 10 short-circuit between terminals (not shown). The code is set depending on whether the jumper wire 10 is connected or not, and the code setting using the jumper wire 10 is performed by cutting a predetermined jumper wire 10 among the plurality of jumper wires 10 connected between the terminals.

However, the transmitter with the above configuration has the following drawbacks when setting the house code and unit code.

When installing the transmitter, open the upper and lower cabinets 5 and 6 of the assembled transmitter by removing screws, etc., and after setting the code, open the upper and lower cabinets 5 and 6 of the assembled transmitter.
Lower cabinets 5 and 6 had to be assembled.

In many cases, the boards are provided in the upper and lower cabinets 5 and 6, respectively, and in this case, each board is connected by a lead wire 9, so when the upper and lower cabinets 5 and 6 are opened and closed, the lead wire 9 is connected. There were many cases of poor contact or disconnection at the soldered parts.

After opening the upper and lower cabinets 5 and 6 and setting the code, when closing the upper and lower cabinets 5 and 6, the lead wires 9 that connect the respective boards provided in the upper and lower cabinets 5 and 6 are returned to their original state. The lead wire does not always return to its original position, and if the position of the lead wire shifts, it may have an adverse effect on the wireless directivity characteristics.

If a malfunction occurs after installing a transmitter with a code set, such as by fixing it to a wall, the code must be changed, but in this case, it is necessary to remove the transmitter and open the upper and lower cabinets. I had to reconfigure the code.

Incidentally, if a switch for setting the code (jumper wire, etc.) is installed outside the main unit, the above drawback can be solved, but in home control systems, security systems, etc., the switch may move for some reason. If the code were to change, it would cause the equipment to malfunction, which could cause not only equipment confusion but also a disaster, so it was necessary to have a code setting switch built into the main unit.

The present invention has been developed in view of the above points, and provides a transmitter in which code setting can be performed using a switch built into the main body without opening or closing the upper or lower cabinets.

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 4 is a perspective view of the embodiment of the present invention, and Fig. 5 is a perspective view of the embodiment of the present invention.
It is a sectional view taken along line AA' in the figure. This figure 4 and 5
In the figure, reference numeral 11 denotes a transmitter body, and the transmitter body 11 has a rectangular parallelepiped box shape and contains an oscillation circuit, a microcomputer, etc. for transmitting signals. Reference numeral 12 denotes a battery storage section recessed in the front side of the transmitter main body 11, and the storage section 12
As shown in FIG. 5, the main body 11 is recessed into a substantially rectangular parallelepiped shape with a bottom.
A plurality of batteries 13 are housed inside. In addition, a window 14 which is a substantially rectangular through hole is provided on the bottom surface of the storage portion 12.
is formed. 15 is a lid of the battery storage section 12, and this lid 15 has a protrusion 15 provided integrally with it.
By engaging with the engagement hole 16 of the main body 11 , it is disposed on the upper surface of the storage portion 12 so as to be flush with the upper surface 17 of the main body 11 . Reference numeral 19 denotes a board installed inside the main body 11, and an oscillation circuit, a microcomputer, etc. are arranged on this board 18. Note that the oscillation circuit, microcomputer, etc. operate using the battery as a power source. 20 is a code setting switch provided on the board 19 at a position corresponding to the window 14 of the storage section 12, and the switch 20 has a knob 21 located at the window 1 as shown in FIG.
A plurality of cords are arranged in the storage section 12 so as to face the house code 4, and by moving the knob 21 back and forth, the above-mentioned house code and unit code can be set. In addition, in FIG. 5, 22 is a bottom plate.

In the installation method of the embodiment having the above configuration, first, the packaged transmitter is unpacked and taken out. (Usually, in this state, the battery 13 is not stored in the battery storage section 12.) Next, if the battery storage section 12 is equipped with a lid 15, the lid 15 is removed to expose the storage section 12. Next, the transmitter is installed at a predetermined location, and a code setting switch 20 installed in the storage section 12 is used to set a code according to the environment. Finally, the battery 13 is stored in the battery storage section 12, and it is checked to see if there are any malfunctions or other inconveniences, and if any inconvenience is found, measures such as changing the code are taken.

Therefore, according to the transmitter of the present embodiment, there is no need to take the trouble of disassembling the assembled main body 11, and the code of the transmission signal can be set simply by removing the lid 15 of the battery compartment 12. Since the switch 20 for setting the code is installed inside the storage part 12 of the main body 11, there is no possibility that the code will be changed by touching the switch 20 by mistake.

Incidentally, if the transmitter with the above configuration is equipped with a means to detect and transmit an abnormality caused by removing the battery, a third party with malicious intent may attempt to change the transmitter's house code or unit code. Since the battery 13 must be removed in order to change the code, it is also possible to prevent malicious code changes like this.

It should be noted that the switch used in the embodiment of the present invention has been described as one in which the code is set by moving it up and down, but as shown in FIG. It may also be used as a switch for other purposes.

According to the present invention, a switch for setting the code of the transmitted signal is built into the battery compartment of the main body, so it is not necessary to take the trouble of disassembling the main body assembled as in the past to set the code. Of course, when the main unit is installed, the power cord can be set using a switch installed inside the storage area where the battery is not stored. In other words, it is very easy to set the code without disassembling the main unit, and it is also very easy to change the code.Moreover, since it is installed inside the battery compartment, there is no need to accidentally change the code after setting the code. There is no chance that it will cause a malfunction. Therefore, it is possible to eliminate the drawbacks that conventionally occur due to disassembling the main body, and it is possible to reduce the cost of the transmitter by improving reliability and simplifying the installation work.
