Description

Technical Field

[0001] The present invention relates to the field of intelligent control technology, and in particular to an intelligently controlled gas generator set and a control method. Background Art

[0002] Gas generator sets are a new type of generator set developed to meet environmental protection needs. With the advantages of light weight and small size, it is now common to rent gas generator sets for use at construction sites or purchase gas generator sets as backup power sources in fixed places. However, gas generator sets used for rental are often transported, and gas generator sets used as backup power sources are in a silent state for a long time. In both cases, there is a possibility that surrounding objects may fall and damage the machine itself, resulting in failures that cannot be discovered in time. What's worse, there are also cases of theft and replacement of inferior parts. However, the existing technology only monitors the operation of the gas generator set when it is turned on, and lacks a technical solution that can monitor the status of the gas generator set itself when it is turned off. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides the following technical solutions: an intelligently controlled gas generator set, comprising a gas generator set, and further comprising:

[0004] The weight sensor is arranged on the base of the gas generator set and is used to monitor the weight of the gas generator set.

[0005] The vibration sensor is arranged on the outer surface of the gas generator set.

[0006] The sound sensor is arranged on the outer surface of the gas generator set and is used to monitor the sound within a set frequency range.

[0007] Photometric rangefinder, used to emit laser to the ground for distance measurement in real time.

[0008] The processing core is used to receive the ranging information of the laser rangefinder and compare it with the set ranging value, and control the opening and closing of the weight sensor, vibration sensor and sound sensor according to the comparison result. The processing core is connected to a storage module, which is used to store the signal received by the processing core and attach a timestamp.

[0009] Preferably, the set distance measurement value is the distance information measured by a laser rangefinder when the gas generator set is stationary on the ground.

[0010] Preferably, the control method of the intelligently controlled gas-fired generator set is also included, comprising the steps of:

[0011] S1. The processing core compares the real-time distance measurement information of the laser rangefinder with the set distance measurement information. When the real-time distance measurement information is equal to the set distance measurement information, the weight sensor, vibration sensor and sound sensor are turned on and the next step is executed. Otherwise, the weight sensor, vibration sensor and sound sensor are turned off.

[0012] S2. The processing core detects whether there is a matching signal of other corresponding sensors in the storage module based on the signal of the sound sensor or the vibration sensor. If the signal of the sound sensor or the vibration sensor matches the signal of other corresponding sensors, the next step is executed, otherwise no response is made.

[0013] S3. The processing core sends out an alarm signal until the alarm signal is manually turned off.

[0014] Preferably, in step S1, when the real-time distance measurement information of the laser rangefinder is equal to the set distance measurement information, the processing core compares the measured weight information with the set weight, and executes step S2 when the measured weight information is equal to the set weight, otherwise executes step S3.

[0015] Preferably, when the measured weight information is not equal to the set weight, the measured weight information is overwritten with the set weight through manual intervention so that the weight information after manual intervention becomes the new set weight. After the set weight is changed, the processing core re-executes step S1.

[0016] Preferably, in step S2, when the sound sensor senses the sound of the set frequency, the processing core detects the vibration signal in the storage module within the corresponding time. When the processing core receives the sound signal and there is a vibration signal at the corresponding time point, step S3 is executed, otherwise no response is made.

[0017] Preferably, in step S2, when the processing core receives the signal sensed by the vibration sensor, the processing core detects the change of weight information within the set time. When the processing core receives the vibration signal and receives a signal that the weight information has changed when the set time arrives, step S3 is executed, otherwise no response is made.

[0018] Compared with the existing technology, the intelligently controlled gas generator set has the following beneficial effects:

[0019] (1) A laser rangefinder is set up to intelligently determine whether the gas generator set is in a static state or an abnormal state of non-static state through distance measurement information;

[0020] (2) Setting up sound sensors to monitor the sounds of objects that may cause damage to the gas generator set, and combining them with vibration sensors to confirm the damage;

[0021] (3) A vibration sensor is set to detect the vibration of the gas generator set, and judge whether the vibration causes the loss of parts based on the weight change when the set time is reached.

[0022] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 4 The present invention provides an intelligently controlled gas-fired generator set, comprising a gas-fired generator set, and further comprising:

[0029] The weight sensor is arranged at the base of the gas generator set to monitor the weight of the gas generator set. Whether an object falls on the gas generator set, or the parts of the gas generator set are stolen, or the standard parts are replaced with other non-standard parts, the weight will change. The present invention uses multiple sensors to screen the reasons for the weight change and intelligently judge whether there is any abnormality in the gas generator set standing on the ground.

[0030] The vibration sensor is arranged on the outer surface of the gas generator set and is used to monitor the vibrations inevitably generated by various operations of the gas generator set.

[0031] The sound sensor is set on the outer surface of the gas generator set to monitor the sound within the set frequency range. The set frequency is the sound frequency related to the material of the gas generator set itself, such as the common metal frequency, which is used to determine whether the object that makes the sound has the hardness to damage the gas generator set. For example, the sound frequency of wooden products is different from that of metals. The hardness of wooden products is obviously not as good as that of metals. The impact of wooden products on the gas generator set is unlikely to damage the outer shell of the gas generator set, so there is no need to respond to it.

[0032] The photometric rangefinder is used to emit laser to the ground in real time for distance measurement, and to intelligently determine whether the gas generator set is stationary on the ground in real time. The weight sensor usually calculates the weight by detecting the pressure in the same direction as gravity. When the gas generator set is hoisted or lifted, the pressure will change, which will lead to inaccurate detection values ​​of the weight sensor. Therefore, a laser rangefinder is used to eliminate this abnormal state.

[0033] The processing core is used to receive the distance information of the laser rangefinder and compare it with the set distance value, and control the opening and closing of the weight sensor, vibration sensor and sound sensor according to the comparison result. Specifically, the distance value is set to the distance information measured by the laser rangefinder when the gas generator set is stationary on the ground. That is, when the distance information of the laser rangefinder is equal to the distance setting value, it means that the gas generator set is in a state of being stationary on the ground. At this time, the weight sensor, vibration sensor and sound sensor are turned on for monitoring; when the distance information of the laser rangefinder is not equal to the set value, it means that the gas generator set is in an abnormal state during transportation. The sound, vibration and weight changes that are bound to occur in the abnormal state should be eliminated, so the weight sensor, vibration sensor and sound sensor are turned off, thereby realizing the automatic intelligent control of the monitoring function on and off without manual intervention.

[0034] The processing core is also connected to a storage module for storing the signals received by the processing core and attaching a time stamp, so that the processing core or an operator can trace back the time when a signal change occurs when necessary.

[0035] It also includes a storage battery to support the continuous operation of the corresponding electronic equipment, and when the power is low, a corresponding alarm signal is issued.

[0036] The control method involved in the present invention comprises the steps of:

[0037] S1. The processing core compares the real-time distance measurement information of the laser rangefinder with the set distance measurement information. When the real-time distance measurement information is equal to the set distance measurement information, the weight sensor, vibration sensor and sound sensor are turned on and the next step is executed. Otherwise, the weight sensor, vibration sensor and sound sensor are turned off.

[0038] S2. The processing core detects whether there is a matching signal of other corresponding sensors in the storage module based on the signal of the sound sensor or the vibration sensor. If the signal of the sound sensor or the vibration sensor matches the signal of other corresponding sensors, the next step is executed, otherwise no response is made.

[0039] S3. The processing core sends out an alarm signal until the alarm signal is manually turned off.

[0040] In step S1, when the real-time distance measurement information of the laser rangefinder is equal to the set distance measurement information, the processing core compares the measured weight information with the set weight. When the measured weight information is equal to the set weight, the next step S2 is executed, otherwise the alarm is directly executed in step S3. This prevents the loss of parts during the lifting process, especially the possibility of replacing inferior parts or cutting corners during the maintenance or repair of gas generators. For example, the weight information detected when it is placed on the repair table or on the ground before repair is compared with the weight information detected for the first time when it is placed on the repair table or on the ground after the system is turned on after repair, so that the weight change before and after repair can be intuitively found.

[0041] When the measured weight information is not equal to the set weight, the measured weight information is overwritten with the set weight through manual intervention so that the weight information after manual intervention becomes the new set weight. After the set weight is changed, the processing core re-executes step S1. The initial weight can be preset as the initial weight of the gas generator set when it leaves the factory, or the weight information measured for the first time can be overwritten as the initial weight through manual intervention when step S1 is executed for the first time. Manual intervention coverage operations are performed through conventional measures such as setting special switches and manually connecting the processing core to modify, so that normal modifications of the gas generator set in subsequent use and other behaviors that actively change the weight can be manually excluded, and the weight information of the gas generator set is no longer restricted to the state at the time of leaving the factory, and can be appropriately changed with time and actual conditions during use.

[0042] In step S2, when the sound sensor receives a sound signal of a set frequency, the processing core detects the vibration signal in the corresponding time in the storage module. If there is a corresponding vibration signal at the corresponding time point of the sound signal, step S3 is executed, otherwise no reaction is made. When the sound sensor receives a sound within the set frequency and there is also a vibration signal within the corresponding time, it means that there is an object that can damage the gas generator set and has caused a collision with the gas generator set. It is necessary to manually check the degree of damage to prevent possible failures when starting up and using it in the future; when the sound sensor receives a sound within the set frequency but there is no vibration signal within the corresponding time, it means that although there is an object that can damage the gas generator set and has fallen, it has not hit the gas generator set itself; when a sound that is not within the set frequency occurs, it means that the object will not cause damage to the gas generator set, so the sound of the non-set frequency is ignored. As for whether the object has other effects on the gas generator set, it is determined by the vibration sensor. The sound sensor is set on the outer surface of the gas generator set, and also includes detecting that although the object itself does not have the possibility of damaging the gas generator set, its impact force is large enough to cause the gas generator set itself to emit a sound of the set frequency.

[0043] In step S2, when the processing core receives the signal sensed by the vibration sensor, the processing core detects the change of weight information within the set time. When the processing core receives the vibration signal and receives the signal of weight information change when the set time arrives, step S3 is executed, otherwise no reaction is made. The operation of the gas generator set body will inevitably produce vibration. In the case of artificially concealing the sound, it can only be monitored by vibration. When a large single vibration occurs, it is usually an accident, such as the above-mentioned material package that is not enough to cause the set frequency sound falling on the gas generator set. At this time, the change of weight information within the continuous set time is detected to determine whether the material package falls after the impact or presses on the gas generator set after the impact. When the set time arrives, the weight changes, indicating that the material package has fallen and pressed on the gas generator set; when the weight changes within the set time but the weight does not change when the set time arrives, it means that the material package has fallen to the ground within the set time. When the gas generator set is operated manually, such as loosening, tightening or even disassembling the connection parts, the size of the vibration, the interval of the vibration, etc. can be adjusted manually, but it is impossible to accurately determine the cause of the vibration. Therefore, the weight monitoring is restarted after each vibration, without considering factors such as the interval time of the vibration. Only when the weight changes when the set time is completed can the status of the gas generator set be determined, and it can be accurately determined whether the parts have been stolen. This prevents the operator from simply loosening or tightening the relevant parts to generate vibration during normal operations, and also prevents false alarms caused by the operator removing the parts for simple cleaning and then reinstalling them.

[0044] On the basis of the above implementation scheme, the processors, modules, corresponding control programs, algorithm programs and other supporting technologies mentioned in the present invention can be implemented in combination with existing electrical technology, information technology, software technology and general protocols. They are not within the scope of protection required by the present invention and will not be described in detail in this application.

[0045] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.
