As shown in FIG. 3 and FIG. 5 , in the second embodiment, the method for routinely automatically checking whether the street lights are normal can be programmed as a software and stored in the memory 20 . Since each second wireless transceiver device 32, 32a, 32b may malfunction and cannot successfully transmit information to other devices, the street lamp system 1 will be in a normal working mode, and regularly execute the routine automatic check in the memory 20 whether the street lamp is The software of the normal method, at this time, the streetlight system 1 will proceed to step 201: each second wireless transceiver device 32, 32a, 32b sends a routine report message C3 to the second master wireless transceiver device 12.

Each street lamp device 30, 30a, 30b will periodically generate routine report messages C3, C3a, C3b, respectively. The routine report messages C3, C3a, C3b include the current state data of the corresponding street lamp device 30, 30a, 30b, such as asking about the brightness of the bulb , bulb temperature, power consumption and connection status...etc. According to the connection sequence of the serial wireless method L2, the second wireless transceiver device 32b of the street lamp device 30b farthest from the second main wireless transceiver device 12 will first send a routine report message C3b to the second wireless transceiver device of the street lamp device 30a Device 32a; after the second wireless transceiver device 32a receives the routine report message C3b, the second wireless transceiver device 32a will send the routine report message C3a of the street lamp device 30a and the routine report message C3b of the street lamp device 30b to the street lamp together The second wireless transceiver device 32 of the device 30; after the second wireless transceiver device 32 receives the routine report messages C3a, C3b from the second wireless transceiver device 32a, the second wireless transceiver device 32 will send the routine report information of the street lamp device 30 The return message C3 , the return message C3 a of the street lamp device 30 a and the report message C3 b of the street lamp device 30 b are sent to the second master wireless transceiver device 12 together.

Next, the street light system 1 will go to step 202: determine whether all routine report messages C3, C3a, C3b are received.

After the second main wireless transceiver device 12 receives the routine report message, the processor 13 will judge whether each routine report message C3, C3a, C3b is indeed received; The wireless connection function of 30b is normal, and the content of the routine report message C3, C3a, C3b can be interpreted to determine the status of the street lamp device 30, 30a, 30b and whether other functions are operating normally, so the routine automatic check of whether the street lamp is normal Method can end.

However, as shown in FIG. 4, if the second wireless transceiver device 32a fails or encounters other radio wave interference and disconnects from the second wireless transceiver device 32, the second wireless transceiver device 32b sends a routine report message C3b to the street lamp After the second wireless transceiver 32a of the device 30a, the second wireless transceiver 32a cannot send the routine report message C3a, C3b to the second wireless transceiver 32 because of disconnection; therefore, the second wireless transceiver 32 can only Send the routine report message C3 generated by its corresponding street lamp device 30 to the second master wireless transceiver device 12 . Therefore, the processor 13 will judge that only the routine report message C3 has been received, and no routine report messages C3a, C3b have been received; at this time, the streetlight system 1 will proceed to step 203: the first master wireless transceiver device of the gateway 10 11 Make an inquiry status request C4 to at least one first wireless transceiver device 31a, 31b corresponding to the return message C3a, C3b.

After the processor 13 judges that the routine report messages C3a, C3b have not been received, it will judge that the streetlight devices 30a, 30b corresponding to these routine report messages C3a, C3b may be faulty, so the first master wireless transceiver device 11 will generate an inquiry state Request the packet of C4, and broadcast the query status request C4 to the first wireless transceiver device 31a, 31b or the second wireless transceiver device 32a, 32b of the street lamp device 30a, 30b, that is, send the query status request C4 to the corresponding routine report The first wireless transceiver device 31a, 31b or the second wireless transceiver device 32a, 32b for the message C3a, C3b. Inquiry Status Request C4 will inquire about bulb brightness, lamp Bubble temperature, power consumption and connection status...etc. The first wireless transceiver device 31a, 31b or the second wireless transceiver device 32a, 32b can process the inquiry status request C4 separately or simultaneously, so as to prevent one of the transceiver devices from failing to process the message. After the first wireless transceiver device 31a, 31b or the second wireless transceiver device 32a, 32b receives the query status request C4, it will send a reply through the first wireless transceiver device 31a, 31b or the second wireless transceiver device 32a, 32b respectively The message is sent to the first master wireless transceiver device 11; in this way, the first master wireless transceiver device 11 can further confirm the status of the street lamp devices 30a, 30b and whether other functions are operating normally according to the received reply message. In this embodiment, since only the second wireless transceiver 32a is faulty, the first wireless transceivers 31a, 31b can still operate normally, so the first master wireless transceiver 11 can still receive the transmissions from the first wireless transceivers 31a, 31b. However, if the street lamp device 30a fails or is powered off so that the first master wireless transceiver device 11 cannot operate, the first master wireless transceiver device 11 will not receive the reply message. To the reply message sent by the first wireless transceiver device 31a, in this way, it can also be confirmed that the street lamp device 30a has a serious fault, and staff can be arranged to repair the street lamp device 30a.

With the design of the street lamp system, the method for actively checking the state of the street lamp and the method for routinely automatically checking whether the street lamp is normal or not, each street lamp device can be wirelessly connected at the same time through the star wireless method and the serial wireless method; wherein the star wireless The connection speed of the method is fast, which can achieve the effect of fast execution of the inspection; the serial connection wireless method will connect each street light device one by one. In the process of connecting one by one, if any street light device fails or is affected by signal loss or interference If the status cannot be connected after checking the status, then the star wireless method can be used to reconnect to the street light device to confirm whether there is a fault, so as to improve the quality of fault inspection.

It should be noted that the above is only an example, but not limited to the example. For example, those that do not deviate from the basic structure of the present invention should be within the scope of rights claimed by this patent, and the scope of the patent application should prevail.
