In order to illustrate the present invention more clearly, the preferred embodiments are described in detail below along with the drawings. Referring to FIGS. 1 to 3 , a bright light debugging system 100 according to a preferred embodiment of the present invention includes a host 10 and a plurality of bright light controllers 20 connected in series to the host 10 in a daisy chain manner. In other preferred embodiments, only one bright light controller 20 can be connected in series to the host 10 or two or more other bright light controllers 20 can be connected in series to the bright light controller 20. The operation method is the same as in this preferred embodiment. Example is the same.

The host 10 has a wireless module 11. Through the wireless module 11, it receives external operations in a wireless manner or accepts external operations in a wired manner to send a signal packet A. The signal packet A includes an initial Address A1, a target address A2 and a control instruction A3. The control instruction A3 can cause the bright light controller 20 to control electronic equipment such as an electronic display signage 30, lamps or speakers electrically connected to it to search for lights and display text. Mark or flash and other corresponding action instructions. The host 10 receives a confirmation packet B within a predetermined time after sending the signal packet A. If the confirmation packet B is received within the predetermined time, the host 10 determines that the status is normal. , if the confirmation packet B is not received within the predetermined time, the status The state is abnormal. Since the delay of electronic signal transmission is on the order of milliseconds, the aforementioned predetermined time can be set to several milliseconds, tens of milliseconds or hundreds of milliseconds according to actual requirements.

The signal packet A sent by the host 10 starts from the first bright light controller 20 on the daisy chain and is transmitted backward along the daisy chain. The bright light controller 20 on the daisy chain has a control circuit board 22. The control circuit board 22 There is a control unit 24. The control unit 24 receives the signal packet A and determines whether the bright light controller 20 where it is located matches the target address A2. If not, the signal packet A continues to be transmitted backward along the daisy chain. If it matches, Then the signal packet A is received and no longer transmitted backward, and the control unit 24 executes the control instruction A3 according to the content of the signal packet A and sends the above-mentioned confirmation packet B, so that the confirmation packet B is transmitted backward along the daisy chain to the host 10 take over.

When the status of all bright light controllers 20 is normal, the confirmation packet B will be sent by the bright light controller 20 matching the target address A2 and transmitted to the host 10 along the daisy chain for reception. However, when the control unit 24 of the bright light controller 20 that matches the target address A2 fails, or when there is a failure of the control unit 24 of at least one bright light controller 20 before the target address A2, the signal packet A will not be delivered. The confirmation packet B is not sent, or the signal packet A cannot be delivered to the light controller 20 that matches the target address A2. The aforementioned two abnormal conditions will cause the host 10 to fail to receive the confirmation packet B. Therefore, if the host 10 does not receive the confirmation packet B within the predetermined time, it can be determined that the status of at least part of the bright light controllers 20 on the daisy chain is abnormal.

The above-mentioned way of judging whether the bright light controller 20 meets the target address A2 is to set the starting address A1 to 1 and the target address A2 to 3, and then the host 10 sends the signal to After the packet A is transmitted to the first bright light controller 20, the control unit 24 of the first bright light controller 20 will compare the target address A2 (target value) and the starting address A1, which is the current value (current value) are 3 and 1 respectively and it is judged that they do not match, so the starting bit After the address A1 is added to the set count value (in this preferred embodiment, the count value is 1, in other embodiments it can be set to different values according to requirements) once it becomes 2, it is transmitted backward along the daisy chain together with the signal packet A. to the second bright light controller 20.

Then the control unit 24 of the second bright light controller 20 compares the target address A2 with the current value of the starting address A1 which has been accumulated once. At this time, the target address A2 and the current value are 3 and 2 respectively, and it is judged Therefore, after the current value is added to the count value to become 3, the signal packet A is transmitted backward along the daisy chain to the third bright light controller 20, and the control unit 24 of the third bright light controller 20 determines the target position. Address A2 is 3, and the current value obtained by accumulating two count values starting from the starting address A1 is also 3. The bright light controller 20 where it is located matches the target address A2, so the signal packet A is received and stored. Then the signal packet A is transmitted backward along the daisy chain, the control instruction A3 is executed and the confirmation packet B is sent to be transmitted backward along the daisy chain; the third bright light controller 20 is the light that matches the target address A2 Light controller 20.

To further describe other structures of the above preferred embodiment, please refer to Figures 1 to 3. The host 10 has an output interface 12 and an input interface 14. The output interface 12 has two first power supplies, which are positive and negative poles respectively. pin 121, a first signal pin 122 and a first confirmation signal pin 123. The input interface 14 has two second power pins 141 which are positive and negative respectively, a second signal pin 142 and a first 2. Confirm signal pin 143. The control circuit board 22 of the bright light controller 20 has an input port 221 and an output port 222. The input port 221 has two power input pins 2211 for positive and negative poles, a signal input pin 2212 and a confirmation Signal input pin 2213. The output port 222 has two power output pins 2221 for positive and negative poles respectively, a signal output pin 2222 and a confirmation signal output pin 2223.

The input port 221 is used for electrical connection with the output port 222 of the host 10 or another bright light controller 20 , for example, between the first bright light controller 20 and the host 10 Between the two power input pins 2211 and the two first power pins 121, the signal input pin 2212 and the first signal pin 122, the confirmation signal input pin 2213 and the first confirmation signal pin 123 are respectively connected through wires. Electrical connection; the two power input pins 2211 and the two power output pins 2221, the signal input pin 2212 and the signal output pin 2222 between each bright light controller 20 and the previous bright light controller 20, the The confirmation signal input pin 2213 and the confirmation signal output pin 2223 are electrically connected through wires respectively.

The output port 222 is used for electrical connection with the input port 221 of the host 10 or another bright light controller 20 , for example, the two power output pins 2221 and the two third power output pins 2221 between the last bright light controller 20 and the host 10 The two power pins 141, the signal output pin 2222 and the second signal pin 142, the confirmation signal output pin 2223 and the second confirmation signal pin 143 are respectively electrically connected through wires; each of the bright light controller 20 and Between the two power output pins 2221 and the two power input pins 2211 of the latter bright light controller 20, the signal output pin 2222 and the signal input pin 2212, the confirmation signal output pin 2223 and the confirmation signal input The pins 2213 are electrically connected through wires respectively. Moreover, the confirmation signal input pin 2213 and the confirmation signal output pin 2223 are electrically connected in a bypass manner, so that the confirmation packet B will not pass through the control unit 24 for bypass transmission of the confirmation on the daisy chain. The acknowledgment packet B is encapsulated so that the delivery of the acknowledgment packet B is not affected by whether the control unit 24 is faulty or not.

The control circuit board 22 has a bright light control port 26. The bright light control port 26 is electrically connected to the control unit 24. It is controlled by the control unit 24 and provides power from the two power input pins 2211 for connecting to the bright light. electronic equipment such as electronic display signage, lamps or speakers. In this preferred embodiment, the bright light control port 26 is electrically connected to an external electronic display signage 30 through a flat cable. The electronic display signage 30 is in the shape of a strip. LED display.

Please refer to FIG. 5 . In order to avoid insufficient voltage for the bright light controller 20 at the back end of the daisy chain to drive the electronic display signage 30 , in other preferred embodiments, more than one light source can be used. The input port 221 of the bright light controller 20 further includes two power supply pins 2214, which are positive and negative poles respectively, for inputting power to increase the voltage of the power output by the two power output pins 2221 of the same bright light controller 20, thereby enabling a daisy chain. The back-end light controller 20 can operate well to drive the electronic display signage 30. In addition, when all bright light controllers 20 adopt the configuration that the input port 221 includes two power supply pins 2214, since the input port 221 and the output port 222 will have six pins and four pins, there will be a significant difference. This can be used as an instruction when the user installs the bright light controller 20 in series, and further has an anti-fooling effect when the bright light controller 20 is installed in series in a daisy chain manner on the host 10, avoiding the electrical connection of the bright light controller 20. The direction is reversed.

Please refer to FIGS. 1 to 3 . When the host 10 needs to further determine whether the bright light controller 20 causing the abnormal status is the bright light controller 20 of the target address A2 , please refer to FIG. 4 . When the host 10 determines that the status is abnormal, it sends a test signal AA to the previous bright light controller 20 of the target address A2, for example, the second bright light controller 20 in this preferred embodiment. The test signal AA Including the confirmation packet A, the host 10 determines whether the faulty bright light controller 20 is the bright light of the target address A2 by whether it receives another confirmation packet B within a predetermined time after sending the test signal AA. Controller 20.

The above-mentioned bright light controller 20 executes a bright light debugging method, as shown in the method step flow chart in Figure 6, and please refer to Figures 1 to 3. The steps include:

(S01) Set up a bright light system: connect one bright light controller 20 to more than one bright light controller 20 in series in a daisy chain manner.

(S02) The host sends a signal packet: The host 10 sends a signal packet A containing the control command A3 to the bright light controller 20 at the target address A2.

(S03) The target address sends back a confirmation packet: When the light controller 20 of the target address A2 receives the signal packet A, it will execute the control command A3 of the signal packet A and send a confirmation packet B to confirm the Packet B is transmitted backward along the daisy chain to the host 10 for reception.

(S04) The host determines whether the status is abnormal: The host 10 determines whether the status is normal or abnormal by receiving the confirmation packet B within a predetermined time after sending the signal packet A. If the confirmation packet is received within the predetermined time, If packet B is received, the status is determined to be normal. If the confirmation packet B is not received within the predetermined time, the status is determined to be abnormal.

In the above bright light debugging method, in the step of sending back the confirmation packet (S03) from the target address, the confirmation packet B is transmitted backward along the daisy chain in a bypass manner. In this way, when the host 10 connects multiple bright light controllers 20 in series, the step of confirming whether the target address is abnormal (S05) can be performed.

The step of confirming whether the target address is abnormal (S05) is when the host 10 determines that the status is abnormal in the step of the host judging whether the status is abnormal (S04), as shown in Figure 4, to the previous one of the target address A2. The bright light controller 20 sends out a test signal AA containing the signal packet A. When the previous bright light controller 20 receives the test signal AA, it will send another confirmation packet B and pass it backward along the daisy chain to the host 10 for reception. The host 10 determines whether it receives another confirmation packet B within a predetermined time after sending the test signal AA. If it receives it, it determines that the failed bright light controller 20 is the bright light controller 20 of the target address A2.
