Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. The embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The embodiment of the invention can be used for determining the fault reason scene of the street lamp controller. Fig. 1 is a schematic diagram of a network architecture used in the embodiment of the present invention. As shown in fig. 1, a street lamp controller is disposed together with a street lamp and connected to the street lamp, the street lamp controller may be connected to a gateway device through a wireless network or a wired network, the gateway device is connected to a street lamp control application system, and the street lamp controller transmits various parameters of street lamp operation to the street lamp control application system through the gateway device, so that the street lamp control application system controls and detects the operation state of each street lamp. The street lamp controller may include a Micro Controller Unit (MCU), a metering chip, and a relay chip. The MCU is used for operating a program to perform data processing, and can be realized by an STM32F103 chip, for example; the metering chip can acquire operating parameters such as voltage, current and the like in the operation of the controller; the street lamp controller can control the on and off of the output of the street lamp through the relay chip.
The embodiment of the invention provides a method for determining a fault reason, which can be used for a street lamp controller shown in fig. 1, and as shown in fig. 2, the method comprises the following steps.
101, when detecting that the communication between the street lamp controller and the gateway device is abnormal, the street lamp controller collects the operation parameters of the street lamp controller.
The operation parameters are used for determining the fault reason of the street lamp controller. The street lamp controller can detect whether the communication with the gateway equipment is abnormal or not. When the street lamp controller detects that the communication between the street lamp controller and the gateway equipment is abnormal, the fault reason can be judged through the operation parameters of the street lamp controller.
The street lamp controller can acquire the operation parameters of the street lamp controller, and the operation parameters can include any one or more of the following parameters: voltage value, current value, received signal strength, metering matching state, Flash memory (Flash) parameter, etc.
It should be noted that the street lamp controller may determine whether the communication with the gateway device is abnormal by sending a heartbeat packet. For example, if the street lamp controller does not receive a response to the heartbeat packet from the gateway device within 15 minutes, it may be determined that an abnormality occurs in communication with the gateway device.
And 102, the street lamp controller determines the target fault reason of the street lamp controller according to the operation parameters.
After the street lamp controller collects the operation parameters, the target fault reason of the street lamp controller can be determined according to various operation parameters and the preset parameter standard.
Specifically, when the operation parameter acquired by the street lamp controller includes a voltage value, whether the target fault cause is equipment overvoltage or not can be judged according to whether the acquired voltage value is larger than a preset overvoltage standard or not, and the preset overvoltage standard can be set to 260 volts; or whether the target fault reason is equipment under-voltage or not can be judged according to whether the acquired voltage value is smaller than a preset under-voltage standard or not, and the preset under-voltage standard can be set to be 180 volts.
When the operation parameters collected by the street lamp controller comprise a current value, whether the target fault cause is equipment overcurrent or not can be judged according to whether the collected current value is larger than a preset overcurrent standard or not, and the preset overvoltage standard can be set to be 2 amperes; or judging whether the target fault reason is equipment undercurrent according to whether the acquired current value is smaller than a preset undercurrent standard.
When the operation parameters collected by the street lamp controller include the Received Signal Strength, the Received Signal Strength can be collected through the Received Signal Strength Indication (RSSI) value of the Received Signal. The street lamp controller can judge whether the target fault reason is that the signal strength is too low according to whether the collected received signal strength is smaller than a preset received signal strength standard, and the preset received signal strength standard can be set to-85 dbm.
When the operation parameters collected by the street lamp controller comprise the metering matching state, the metering matching state can be determined according to the metering matching result calculated by the metering chip. The street lamp controller can judge whether the target fault reason is metering matching mismatching according to whether the collected metering matching state is a preset metering matching standard state, and the preset metering matching standard can be set to be that the metering matching result of the metering chip is mismatching.
When the operation parameters collected by the street lamp controller comprise Flash parameters, the parameters of each block in Flash can be collected. The street lamp controller can compare the collected Flash parameters with preset Flash parameter standards so as to judge whether the target fault reason is a Flash fault.
In the embodiment of the invention, different operation parameters correspond to different fault reasons, and the street lamp controller can judge according to various operation parameters to determine the corresponding target fault reason.
103, the street lamp controller obtains a target fault code corresponding to the target fault reason based on the corresponding relation between the fault reason and the fault code.
In the embodiment of the present invention, a corresponding fault code is set for each fault cause, that is, a mapping relationship between a fault cause and a fault code is established, so after the target fault cause is determined in step 102, the target fault code corresponding to the target fault cause can be determined according to the mapping relationship between the fault cause and the fault code.
In the embodiment of the invention, each code in the fault codes can be used for indicating the street lamp state, and the street lamp state comprises an opening state and a closing state, so each code in the target fault codes is used for indicating the street lamp state. The fault codes can adopt various coding modes, for example, binary codes can be adopted, and different fault reasons can be represented by different binary codes.
And 104, the street lamp controller controls the street lamp to be switched on and off according to the target fault code, so that the fault detector determines the target fault reason according to the switching on and off of the street lamp.
In the embodiment of the invention, the street lamp controller can transmit the target fault code by turning on and off the street lamp. And each code in the target fault codes indicates the state of the street lamp, and the street lamp controller can control the street lamp to be turned on or off according to the target fault codes.
The target fault code may include one or more code values. The street lamp controller can set a corresponding street lamp state for each coding value and preset the sustainable time length of the street lamp state corresponding to a single code in the target fault code, namely the unit state time length, and then can control the opening and closing of the street lamp through the target fault code.
In general, when the number of times of switching the street lamp is more than 60 times per second, human eyes cannot perceive the turning on and off of the street lamp, that is, normal lighting cannot be affected, so that in the embodiment of the invention, the unit state duration can be preset to be a value less than 1/60 seconds, and each code value in the target fault code can be represented by controlling the turning on and off of the street lamp under the condition that normal lighting is not affected.
Specifically, in the embodiment of the present invention, the fault code may adopt a unipolar code, the unipolar code has only two states, namely, positive and negative, and may represent negative by using a code value of 0 and positive by using a code value of 1. In the embodiment of the present invention, the on-off state corresponding to the preset code value 1 may be an on state, and the on-off state corresponding to the preset code value 0 may be an off state.
This step may have the implementation as: the street lamp controller controls a first time length for opening the street lamp and a second time length for closing the street lamp according to the target fault code based on the unit state time length, wherein the first time length is integral multiple of the unit state time length, and the second time length is integral multiple of the unit state time length.
The street lamp state comprises an opening state and a closing state, so that the street lamp can be switched on and closed at least once in the process of controlling the street lamp to be opened and closed by the street lamp controller according to the target fault code, the process of opening and closing the street lamp at least comprises a first time length for opening the street lamp and a second time length for closing the street lamp, the first time length and the second time length are determined according to each code in the target fault code, and the first time length and the second time length are integral multiples of the time length of a unit state.
It should be noted that, in the process of controlling the opening and closing of the street lamp by the street lamp controller according to the target fault code, the street lamp may be switched on and off for multiple times, so that the process of opening and closing the street lamp may further include a first time period for opening the street lamp, a second time period for closing the street lamp, a third time period for opening the street lamp, a fourth time period for closing the street lamp, and the like.
For example, in the embodiment of the present invention, the corresponding street lamp state is an on state when the preset code value is 1, the corresponding street lamp state is an off state when the preset code value is 0, and the unit state duration is 1 millisecond (ms), which is equivalent to 1000 times per second of switching times of the street lamp. The code value of the target fault code determined by the street lamp controller in step 103 is 1000, and at this time, the street lamp controller controls the street lamp to be turned on and off according to the target fault code as follows: the first time length of the street lamp is 1ms, the second time length of the street lamp is 3ms, and the optical signal output by the street lamp is closed for 3ms after being opened for 1 ms. The first code value of the target fault code is 1, and the street lamp state corresponding to the code value 1 is an open state, so that the street lamp controller controls the street lamp to be opened for 1 ms; the last three code values of the target fault code are all 0, and the street lamp state corresponding to the code value 0 is the off state, so the street lamp controller controls the street lamp to be off for 3 ms. The conversion of the encoded values into a waveform diagram can be shown as a solid line in fig. 3.
It should be noted that, in order to enable the fault detector to determine the cause of the target fault in time, the street lamp controller may periodically control the street lamp to be turned on or off according to the target fault code. Specifically, the street lamp controller may repeatedly perform the process of controlling the street lamp to be turned on and off according to the target fault code within a preset time period. When the target fault causes include more than two, the optical signals output by the street lamps can be controlled according to the target fault codes corresponding to the target fault causes at preset intervals in sequence.
In the embodiment of the invention, when the communication between the street lamp controller and the gateway equipment is abnormal due to faults, the fault reason can be determined through self-checking, the street lamp controls the street lamp to be switched on and switched off according to the target fault code, each code in the target fault code is used for indicating the street lamp state and comprises the switching-on state and the switching-off state, so that the street lamp controller can control the switching-on and the switching-off of the street lamp according to the target fault code, and the fault detector can determine the target fault reason by detecting the switching-on and the switching-off of the street lamp, thereby accurately determining the fault of the street lamp controller without a worker contacting the street lamp controller, realizing the fault location of the street lamp controller, reducing the difficulty of determining the fault reason of the street lamp controller and improving the efficiency of.
In an implementation manner of the embodiment of the present invention, in order to facilitate the fault detector to accurately determine the target fault code according to the optical signal, the street lamp controller may add a verification code to a preset position of the target fault code before step 104, where the verification code is used to indicate the position of the target fault code; then, the street lamp controller takes the target fault code added with the verification code as a target code; at this time, step 104 may be specifically executed as: and the street lamp controller controls the street lamp to output the optical signal according to the target code control target code.
The verification code is used to indicate the location of the target fault code. And after the street lamp controller adds the verification code at the preset position of the target fault code, the street lamp controller controls the street lamp to be turned on or turned off according to the target code. The same verification code can be preset in the fault detector and the street lamp controller, and meanwhile, the preset position relation between the verification code and the target fault code is preset. After the verification code is added to the target fault code, the fault detector can determine the verification code from the code identified according to the opening and closing of the street lamp, and then the target fault code can be accurately determined according to the preset position relation between the verification code and the target fault code.
Specifically, the preset position relationship includes that the verification code is before the target fault code and/or the verification code is after the target fault code, that is, the verification code may be added before the target fault code, the verification code may be added after the target fault code, and the verification code may be added before the target fault code and after the target fault code.
For example, a code value of 1 indicates that the street lamp state is an on state, a code value of 0 indicates that the street lamp state is an off state, and the unit state duration is 1 ms. If the verification code is set to 1101 and the code value of the target fault code is 0001, the target code obtained by adding the verification code to the initial position of the target fault code is 11010001. Therefore, the process that the street lamp controller controls the street lamp to be opened and closed according to the target code is as follows: the first time period for opening the street lamp is 2ms, the second time period for closing the street lamp is 1ms, the third time period for opening the street lamp is 1ms, the fourth time period for closing the street lamp is 3ms, and the fifth time period for opening the street lamp is 1 ms.
In the embodiment, the street lamp controller can periodically control the street lamp to be opened and closed according to the target codes, the fault detector can determine the two target fault codes respectively through the opening and closing of the street lamp in two periods and the verification code and the preset position, and then the fault detector determines whether the identified target fault codes are accurate or not by comparing the consistency of the two target fault codes, so that the accuracy of the target fault code judgment is improved.
The embodiment of the invention provides another method for determining a fault reason, which is used for a fault detector, wherein the fault detector can be carried by a worker to the vicinity of a street lamp when the fault of a street lamp controller needs to be detected, as shown in fig. 4, the method comprises the following steps.
And 201, turning on and off the street lamp within a preset time period by the fault detector.
In the embodiment of the invention, the street lamp controller can transmit the target fault code by turning on and off the street lamp. The fault detector determines the fault code of the fault reason of the street lamp controller by detecting the on and off of the street lamp within a preset time period. The length of the preset time period is required to be greater than or equal to the product of the number of the code values of the target fault codes and the unit state duration, so that the fault detector can determine the complete target fault codes, and the unit state duration is the sustainable duration of the street lamp state corresponding to the single code in the target fault codes. The target fault code and the unit state duration in the fault detector can be preset.
Specifically, the fault detector can detect a first time length for opening the street lamp and a second time length for closing the street lamp in a preset time period, wherein the first time length is an integral multiple of a unit state time length, the second time length is an integral multiple of the unit state time length, and the unit state time length is a sustainable time length of a street lamp state corresponding to a single code in the target fault code.
The fault detector detects that the street lamp is opened and closed, and the street lamp is switched between opening and closing in the opening and closing process, so that a first time length for opening the street lamp and a second time length for closing the street lamp can be obtained, wherein the first time length and the second time length are determined according to each code in the target fault code, and the first time length and the second time length are integral multiples of the unit state time length.
202, the fault detector obtains a target fault code according to the on and off of the street lamp.
The fault detector can obtain the on-off state of the street lamp by detecting the on-off state of the street lamp, and then can determine a target fault code.
Specifically, the process of determining the target fault code by the fault detector according to the turning on and off of the street lamp may be: and the fault detector obtains the target fault code according to the first time length and the second time length on the basis of the unit state time length.
According to the first time length for opening the street lamp and the second time length for closing the street lamp, and the unit state time length corresponding to a single code value, the number of the code values respectively corresponding to the first time length for opening the street lamp and the second time length for closing the street lamp can be determined. And then the target fault code can be determined according to the code value corresponding to each street lamp state.
For example, the fault detector determines that the opening and closing process of the street lamp is: the first time period for which the street lamp is turned on is 1ms, and then the second time period for which the street lamp is turned off is 3 ms. In the embodiment of the invention, the street lamp state corresponding to the preset code value 1 is an open state, the street lamp state corresponding to the preset code value 0 is a closed state, and the unit state duration is 1 ms. Then, according to that the second time length of the street lamp turning-off is 3ms, it can be determined that the street lamp is in the turning-off state for 3ms, and the time length of the unit state is 1ms, so that the second time length of the street lamp turning-off is 3ms and represents 3 coded values, and similarly, the first time length of the street lamp turning-on is 1ms and represents 1 coded value. According to the fact that the street lamp state corresponding to the preset code value 1 is the opening state, the street lamp state corresponding to the preset code value 0 is the closing state, the fault detector can determine that the first time length of the street lamp opening is 1ms to represent the code value 1, the second time length of the street lamp closing is 3ms to represent the code value 000, and therefore the target fault code is 1000.
In order to facilitate the fault detector to accurately determine the target fault code, the street lamp controller may further add a verification code at a preset position of the target fault code, then use the target fault code added with the verification code as the target code, and control the target code to output the light signal of the street lamp according to the target code.
Therefore, when the on and off of the street lamp only represents the target fault code, the code represented by the on and off of the street lamp can be directly determined as the target fault code; when the target fault code added with the verification code is represented by the opening and closing of the street lamp, after the target code represented by the opening and closing of the street lamp is determined, the target fault code can be determined based on the verification code and the preset position.
When the turning on and off of the street lamp indicates that the target code after the verification code is added, step 202 may be specifically performed as: the fault detector obtains a target code according to the first time length and the second time length based on the unit state time length, wherein the target code comprises a verification code and a target fault code, and the verification code is used for indicating the position of the target fault code; the fault detector determines the position of the verification code in the target code according to the verification code; the fault detector obtains a target fault code from the target code according to the position of the verification code.
After the target code indicated by the turning on and off of the street lamp detected in step 201 is identified, the position of the verification code can be determined from the target code because the code value of the verification code is known by the fault detector. And then according to the position of the verification code, combining the preset position relation to obtain a target fault code from the target code. The preset position relationship comprises that the verification code is before the target fault code and/or the verification code is after the target fault code, namely the verification code can be added before the target fault code, the verification code can be added after the target fault code, and the verification code can be added before the target fault code and after the target fault code.
And 203, determining a target fault reason corresponding to the target fault code by the fault detector according to the corresponding relation between the fault reason and the fault code.
The target fault reason is used for indicating the fault of the street lamp controller.
After the target fault code is determined, the fault detector can determine the target fault reason corresponding to the target fault code according to the mapping relation between the fault reason and the fault code, namely, the fault reason of the street lamp controller is determined.
In the embodiment of the invention, when the communication between the street lamp controller and the gateway equipment is abnormal, the fault detector can determine the target fault code by detecting the on and off of the street lamp, so as to determine the fault reason of the street lamp controller, and workers do not need to contact the street lamp controller, thereby reducing the difficulty of determining the fault reason of the street lamp controller and improving the efficiency of determining the fault reason.
In the embodiment of the invention, the street lamp controller can repeatedly execute the process of controlling the street lamp to be opened and closed according to the target fault code within the preset time period, so that the fault detector can determine the coding sequence according to the detected opening and closing of the preset street lamp in the process of determining the target fault code; and then determining the codes which are repeatedly arranged in the coding sequence as target fault codes.
The street lamp controller can repeatedly execute the process of controlling the street lamp to be opened and closed according to the target fault codes within the preset time period, so that the street lamp to be opened and closed within the preset time period detected by the fault detector represents the repeated target fault codes, the fault detector identifies the code sequence as the repeated target fault codes according to the street lamp to be opened and closed within the preset time period, and the code repeatedly arranged in the code sequence is the target fault codes.
