In the circuit module of the tested street lamp controller in this embodiment, the circuit module includes a brightness acquisition circuit module (which uses a photosensitive tube to collect the brightness of the surrounding environment of the street lamp, so as to provide a processor with parameter bases such as automatic light on/off and brightness adjustment), a power parameter acquisition module, a relay on/off circuit module, a 0-10V output circuit module, and the like.
Referring to fig. 1, in a production test method of an automatic street lamp controller, when a certain test in each step starts (some programs are spontaneous, and some receive external command triggers), test contents are output first.
Step 1: inserting a street lamp controller to be tested into a serial port, connecting an upper computer and starting test software;
step 2: when the click is started, the test software writes in IP and PAN ID and issues a firmware version, and when the step is executed, the upper computer software for test should be configured well;
and step 3: after the test software confirms that the firmware version of the tested street lamp controller is correct, the serial port of the tested street lamp controller outputs PASS, the step 4 is entered, before the step is executed, a relay is opened by default, a production test mode is best to default without finding a network, and the production test efficiency is improved;
if the firmware version of the tested street lamp controller is wrong, the serial port of the tested street lamp controller outputs FAIL, and the test is stopped;
and 4, step 4: the light source switching board is powered on and defaults to be a standard light source;
the photosensitive tube receives a brightness signal, and the brightness signal is set as a reference parameter by the brightness acquisition module;
after the calibration is successful, outputting PASS by the serial port of the tested street lamp controller, entering the step 5, and if the calibration is failed, outputting FAIL by the serial port of the tested street lamp controller, and stopping the test;
and 5: the light source switching board is switched to low illumination, the self-sensing relay is closed, and the mark position is recorded;
after the record is successful, the serial port of the tested street lamp controller outputs PASS, the step 6 is entered, if the record FAILs, the serial port of the tested street lamp controller outputs FAIL, and the test is stopped;
step 6: a pin of the light source switching board receives a high level, the light source switching board is automatically switched to high illumination, the self-induction relay is opened and records a mark position, and therefore whether the street lamp is lighted or not is judged when the street lamp is used;
after successful recording, the serial port of the tested street lamp controller outputs PASS, the step 7 is entered, if the recording FAILs, the serial port of the tested street lamp controller outputs FAIL, and the test is stopped;
and 7: software detects whether the voltage and the current are in a preset error range;
when the voltage and the current are within a preset error range, the serial port of the tested street lamp controller outputs PASS, the step 8 is entered, when the voltage and the current are outside the preset error range, the serial port of the tested street lamp controller outputs FAIL, the test is stopped, in the detection of the step, the default voltage of the system is 210V to 230V, and the current is 5mA to 20 mA;
and 8: the software executes the SOS instruction and continuously collects current parameters to judge whether the current change process is 'small → large' (it needs to be explained here that the SOS instruction is a newly added function in the tested street lamp controller, the street lamp can be controlled to enter an SOS lighting mode through a remote management interface, and can be sent at any time to exit and recover to a normal lighting mode, the SOS lighting mode is actually breathing lamp operation in a period of about 2s, and the effects and purposes of alarming and crowd evacuation are achieved);
the current change process is 'small → large', the serial port of the tested street lamp controller outputs 'PASS', the step 9 is entered, otherwise, the serial port of the tested street lamp controller outputs 'FAIL', and the test is stopped;
and step 9: and after the Test is finished, the serial port of the tested street lamp controller outputs 'Test PASS', at the moment, the street lamp controller finishes the Test and passes the Test, and the serial port of the tested street lamp controller outputs the PAN ID, the MAC address and the Internet of things card number.
In the detection steps, when the serial port output FAIL of the tested street lamp controller occurs, the tested street lamp controller is temporarily determined as an unqualified product after the test is stopped, and a detector judges that the product is destroyed, repaired or adopts other processing schemes.
In addition, in order to further improve the efficiency of the production test and strictly control the quality of the product, in step 4, the sampling frequency of the brightness acquisition module is commanded to be at least 5 times, and whether the multi-time sampling data has large-range fluctuation or not is judged, so that whether the sampling is accurate or not is judged, and meanwhile, the sampling is required to be completed within 2 seconds, and the efficiency of the detection step is ensured.
In step 8, the sampling frequency of the current parameter is at least 10 times, and the sampling is completed within 2 seconds, and similarly, whether the sampled data for many times is within a normal working condition range needs to be judged, so that whether the tested street lamp controller is qualified is judged, and meanwhile, the detection is required to be completed within 2 seconds, and the detection efficiency is ensured.
In the steps 1 to 9, when the serial port of the tested street lamp controller does not output the PASS for 5 seconds, the serial port of the tested street lamp controller automatically outputs the FAIL, and in order to improve the quality requirement of the product during production, except for the fault lamp factor of the production software, the tested product which does not output the PASS for 5 seconds is not output, so that the problems that the quality of electric elements is poor, certain links in the production process of PCB boards and the like are not processed in place, the reaction time is too slow, or the detection result cannot be fed back exist, and therefore the products cannot be detected excessively.
The production and measurement method of the street lamp controller is matched with a software system of an upper computer, and the deviation calibration of the photosensitive tube in front of a factory can be carried out on each street lamp controller. And performing systematic test on hardware of the product.
The full-automatic completion can be realized only by sending the starting instruction and the related parameters through the serial port of the upper computer. The operation result is also fed back to the upper computer through the serial port and is visually displayed on the screen.
The whole calibration and test process does not exceed 4 seconds, four circuit boards (four impositions) can be operated simultaneously, and the efficiency is nearly one second.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
