Description
Technical Field
The invention relates to the technical field of sensor parameter configuration, in particular to a parameter configuration method of a micro-power consumption wireless sensor powered by a battery.
Background
Along with the popularization and implementation of the national internet of things, a large number of various sensors are used, and some scenes such as electric power high-voltage equipment and the like which are inconvenient for external power supply all adopt batteries to supply power to the sensors, sample wireless communication and facilitate construction and installation. When the battery is used for supplying power, the power supply capacity of the battery is considered, in order to save electric energy and prolong the service life of the sensor, the sensor is in a dormant state in most of time, only revives in appointed time, samples and measures environmental data, and sends the environmental data to the local side equipment in a wireless mode. The wireless transmission is generally actively controlled by the sensor, so that the required time is short, the power consumption is relatively low, but the receiving has uncertainty and needs longer time. Because the power consumption of wireless transmission and reception is basically similar, in order to save the power consumption, in some scenes, the sensors all transmit in one direction and do not enter a receiving state. This saves at least more than half the power consumption. However, this also causes a problem that when the local end needs to modify the parameter configuration of the sensor, the sensor does not receive the parameter configuration, so that the parameter configuration cannot be realized.
Disclosure of Invention
In order to solve the defects of the prior art, realize the purpose of supporting parameter modification and achieving the same power consumption as single item transmission, the invention adopts the following technical scheme:
a parameter configuration method of a micro-power consumption wireless sensor powered by a battery comprises the following steps:
s1, a detection module of the sensor identifies the environmental data acquired by the sensor;
s2, when detecting that the environmental data exceeds the change threshold, the sensor enters a receiving working mode to receive the issued data of the local side equipment;
and S3, after entering the receiving state, automatically exiting the receiving state after the receiving time threshold value, recovering the periodic one-way transmission working mode, and simultaneously continuing to detect the environmental data.
During engineering construction and maintenance parameter adjustment, local-side equipment is generally required to issue parameters in time so as to acquire the working condition of the sensor, construction and maintenance are further performed, the parameters are actively acquired through the sensor, normal data transmission of a single sensor item is guaranteed, energy consumption is saved, issued configuration data can be actively acquired in time, operations such as parameter adjustment and testing are performed, and the normal operation of the original sensor which periodically enters a receiving state is not influenced.
Further, in step S3, within the receiving time threshold, if there is data issued by the central office device, the receiving state is exited after the receiving is completed, the periodic unidirectional transmission operating mode is resumed, and the detection of the environmental data is continued, otherwise, after the receiving time threshold, the receiving state is automatically exited, the periodic unidirectional transmission operating mode is resumed, and the detection of the environmental data is continued.
Receiving data sent by the local side equipment within a receiving time threshold, wherein a period of time is possibly added between the end of the receiving time threshold, and a sensor is still in a receiving state, so that the time is not wasted, and meanwhile, a periodic one-way sending working mode can be recovered as soon as possible, the influence on normal sending work is reduced, the environmental data is continuously detected as soon as possible, the real-time performance and the continuity of detection are ensured, and the working mode is directly recovered and the detection is continuously performed after the data sent is received within the receiving time threshold; on the other hand, the situation that the received data is incomplete because the sending working mode is directly recovered and the detection is continued if the receiving of the transmitted data cannot be completed within the receiving time threshold is avoided.
Further, the sensor further comprises a periodic receiving working mode, and the periodic one-way sending working mode and the receiving working mode are mutually switched, wherein when the periodic receiving working mode conflicts with the receiving working mode, after one receiving working mode receives the issued data of the local side equipment, the other receiving working mode is switched. The receiving work of one receiving work mode is prevented from being interrupted due to the starting of the other receiving work mode.
Further, the sensor also comprises a periodic receiving working mode, and the periodic unidirectional transmitting working mode and the receiving working mode are mutually switched, wherein when the periodic receiving working mode conflicts with the receiving working mode, the receiving working mode with an earlier receiving state is closed by interrupting the receiving state, and the receiving working mode with a later receiving state is closed by switching. In order to ensure that the acquired parameter data is issued after the local side equipment is updated, the data received at the next time is accurate, and meanwhile, the subsequent receiving time of the previous time, the time for connecting the two times of data receiving and the energy consumption are also saved.
Furthermore, the initial value of the change threshold is lower than the conventional change threshold, the threshold adjusting module is used for adjusting the change threshold, and when the threshold adjusting module monitors that the sensor enters the receiving working mode for multiple times within a fixed time and fails to receive issued data of the local-side equipment, the change threshold is increased, so that the probability of entering the receiving working mode by mistake is reduced.
Further, the sensor is a temperature sensor, the change threshold is a temperature change value in unit time, and when the sensor is installed on a high-voltage line, a hot air blowing device is used for heating the environment of the sensor in an isolated mode; when the sensor is not installed on the high-voltage line, a heating or cooling device is used for heating or cooling the environment of the sensor; the sensor is put into a receive mode of operation. The change threshold is bidirectional, including the change of temperature rise and the change of temperature drop, the sleep cycle of the temperature sensor on the ordinary high-voltage contact is 1 minute, the change of the ambient temperature per minute under the normal condition of actual use does not exceed 0.5 degree (actually, the fastest change condition of the temperature can occur only when the power consumption changes sharply in the working and working hours), the ordinary hot air blower (such as a high-power hot air blower) can enable the temperature to rise by more than 10 degrees per minute, the requirement of the change threshold of the sensor can be met, similarly, the portable small refrigerator or the ice bag for insurance can also meet the temperature drop requirement of the change threshold, and an engineer can complete the change of the ambient temperature of the sensor only by using a conventional temperature raising and lowering device.
Further, the sensor is a humidity sensor, the change threshold is a humidity change value in a unit time, and the environment of the sensor is humidified by using the humidifying device in an isolated manner.
Further, the sensor is a humidity sensor, the change threshold is a humidity change value in unit time, and when the sensor is not installed on a high-voltage line, the environment of the sensor is humidified by directly using haar.
Further, the detection module in step S1 periodically identifies the sensor data to avoid real-time detection of the energy consumption.
Further, the issued data of the central office end device in step S2 is a parameter configuration command.
The invention has the advantages and beneficial effects that:
under the condition of not increasing materials, the problem that power consumption is increased rapidly due to the accidental parameter configuration requirement of a micro-power consumption sensor powered by a battery is solved, and the reliability of equipment is improved.

Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
As shown in fig. 1, the battery-powered sensor performs periodic communication with the office device through wireless transmission, wherein the sensor transmits a single item and receives data through periodically entering a wireless receiving state, thereby saving power consumption. However, if the period is too short, the power consumption is greatly increased, the battery power supply life is greatly shortened, and if the period is too long, the actual operation is inconvenient, the command issuing waiting time of the local side device is too long, and the customer experience is very poor.
As shown in fig. 2, a signal is input to the sensor through an input device, such as a button, so that the sensor enters a receiving state to receive a parameter configuration command of the central office equipment, thereby solving the above-mentioned problems of increased power consumption or inconvenient operation caused by too long or too short cycle. However, a hardware device needs to be added in the scheme, so that the material cost is increased, meanwhile, the added device usually adopts a mechanical contact to enable the sensor to sense that the sensor needs to enter a receiving state, the mechanical contact can greatly increase the unreliability under certain severe environments, and the mechanical contact is triggered by mistake to enter the receiving state, so that the battery is exhausted quickly, and the like. Meanwhile, the mechanical joint brings great quality hidden trouble in the scenes of needing water prevention and the like. And for another example, some scenes are inconvenient to operate the buttons, and for example, the sensors are installed in high-voltage or other dangerous scenes, so that manual operation is inconvenient.
In order to solve the problems, the hardware of the sensor is kept unchanged, and meanwhile, the environment monitored by the sensor (such as the environment temperature of a temperature sensor, the humidity value of a humidity sensor and the like) is artificially changed suddenly and greatly in a short time, and the change greatly exceeds the possible change range of the normal environment; recognizing an abnormal change value in a detection period by software in the sensor, so that the sensor enters a receiving state wirelessly and receives a parameter configuration command of local side equipment; after entering the receiving state, after a period of time, the local side automatically exits the receiving state no matter whether the local side issues a parameter configuration command or not, and the low-power-consumption periodic transmission working mode is recovered; under the normal scene, the one-way wireless transmission characteristic of the sensor is still kept, and the sensor does not enter a receiving state.
For example, the sleep cycle of the temperature sensor at the high-voltage contact is 1 minute, and the ambient temperature does not change more than 0.5 degrees per minute under the normal condition of actual use (actually, the temperature changes fastest only when the power consumption changes sharply at the time of work and work). If the sensor is installed on a high-voltage line, high-power hot air can be used, the temperature of the sensor can be directly raised in the air, the actual measurement is carried out for more than 10 degrees per minute, the unconventional change value of the sensor can be set to be 5 degrees per minute, the sensor is judged to be in a configuration state when the unconventional change value exceeds 5 degrees, and the sensor is kept in a normal working mode when the unconventional change value is lower than 5 degrees. If the sensor is not installed on the high-voltage line, a portable semiconductor small refrigerator (or an ice bag for seafood preservation) is also used, and the sensor is enabled to enter a configuration mode through a cooling mode.
If the humidity sensor is used, a humidifier can be adopted in the same way, and the environmental humidity can be rapidly increased within 1 minute. If the sensor is not installed on a line, the sensor can enter a configuration mode by directly using a mouth to suck air.
The threshold entering the configuration mode can be modified, the initial threshold is lower, an intelligent threshold adjusting function is added, the sensor enters the configuration mode for multiple times within fixed time, and the configuration command of the local side equipment is not received, so that the threshold value of the configuration mode can be increased by the sensor, and the probability of entering the configuration mode by mistake is reduced.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
