Description

Conflict detection method for control rule

Technical Field

The present invention relates to a detection method, and more particularly, to a collision detection method for control rules.

Background

In the control system, with the increase of the number of devices and the sudden increase of application scenes, when the control rules are constructed manually, control rule conflicts easily occur due to different levels of users and different familiarity of the system, so that different actions trigger different effects of the same device at the same time, and a setter cannot be reminded in real time. For example, in a household control system, when the illuminance sensor is higher than a certain value M1, a user wants to dim the light at first, and the user feels that M1 lumens cannot meet the requirement at second, and wants to dim the light at second, so that the lamp can output a larger value M2 lumens, wherein M2 is larger than M1, and the control rules set by the user first and the user second conflict with each other, so that the control system cannot meet the control requirements of a plurality of users; in addition, in the scene control of the control system, the control rule set by the user one is as follows: 1) associating the motion detection sensor MS1 with the lights of zone one and zone two, 2) when detecting that someone is present in zone one, the motion detection sensor MS1 is triggered, light fixture one, light fixture two and light fixture three in zone one are on, light fixture four and light fixture five in zone two are off; and when the second user sets the scene control rule, the third lamp is arranged in the second area, so that when people appear in the first area, the third lamp should be turned off but is turned on due to the set control rule of the second user.

At present, in a control system, there are devices such as executing devices and sensors, and users first Group the devices, for example, dividing the executing device1 and the executing device2 into a Group1, if different users set the following two rules:

rule 1: when the sensor pir1 is triggered, the executive equipment device1 and the executive equipment device2 in the Group1 start working;

rule 2 when the sensor pir1 is triggered, the executive device1 and the executive device2 stop working.

In the two control rules set up, there is a conflict between the execution of the device1, since different actions cannot be triggered by the same sensor pir 1. For the above encountered problem of rule conflict, the conventional solution: for rule 2, firstly analyzing the triggering condition of the sensor pir1, and if the condition is satisfied, searching a rule table related to the sensor pir 1; after finding out the related rules of the sensor pir1, searching all the groups to find out a Group 1; further traversing all the devices in the Group 1; finally, the device1 is found to conflict between rule one and rule two by comparison.

Because the calculation complexity, the number of control rules and the equipment grouping scale of the traditional solution are all related, the system response capability is slowed down along with the increase of the rules, so that when a user sets the control rules at a client and then carries out recursive collision detection by a background, the phenomena of untimely response, unsmooth background system and the like can occur.

Fig. 2 is a schematic diagram of a correspondence between a hash value of the linkage device and linkage information in the storage unit according to the embodiment of the present invention. Referring to fig. 2, the linkage information is stored in the storage unit 200 of the server, the linkage information is linkage information including linkage actions of the sensor and the execution device, besides, the linkage information may also be a name of the sensor, a name of the execution device, and a combination of linkage actions of the sensor and the execution device, or the linkage information includes a name of the execution device and a combination of linkage actions of the sensor and the execution device, the first control rule may include a plurality of items of linkage information and their respectively associated linkage devices, in this embodiment, the first control rule is that when the infrared sensor pir1 is triggered, the light1 in the control system is turned on, the light3 is turned on, and the first control rule may be expressed as:

Rule1：{pir1, light1 on, light3 on}

the first control rule includes the following two pieces of linkage information and associated linkage device information:

1) { (pir1, light1), light1 on }, which indicates that when sensor pir1 triggers, lamp light1 lights up; here, light1 on is the first interlocking information indicating that the lamp light1 is lit, (pir1, light1) are the interlocking device information associated with the first interlocking information light1 on, that is, the sensor pir1 and the lamp light1 are the associated devices associated with the first interlocking information.

2) { (pir1, light3), light3 on }, which indicates that when sensor pir1 triggers, lamp light3 lights up; here, light3 on is second interlocking information indicating that the lamp light3 is lit, (pir1, light3) are interlocking device information associated with the second interlocking information light3 on, that is, the sensor pir1 and the lamp light3 are interlocking devices associated with the second interlocking information.

The server will initialize the memory unit 200 in the memory module first, wherein, the number of the memory unit is larger than the product of the number of the sensors and the number of the executing devices; performing hash calculation on the linkage equipment information associated with each linkage information in the received first control rule to obtain a first key value 100 corresponding to each linkage information one by one; finally, a deformation Rule' for the first control Rule is formed, wherein each first key value 100 corresponds to one linkage information:

Rule1’； {hash(pir1+ light11)， light1 on}， {hash(pir1+ light3)， light3 on}

the HASH is a HASH function, the pir1+ light1 represents a combination of the name of the linkage device information sensor pir1 and the name of the lamp light1, such as splicing of character strings, and other linkage device information and linkage information, and so on. Each calculated HASH value 100 points as an address value to a storage location where the linkage information is stored. As shown in fig. 1, the value of Hash (pir1+ light1) points to the storage unit 200 of the associated linkage information, which is the On light. Similarly, the Hash (pir1+ light3) points to a storage unit of the linkage action of the lamp light3 associated with the sensor pir1, and the storage unit stores the lamp-On action On; in addition, the storage unit may store information "light 1 on", "light 3 on", "light 2 Down", or store linkage information "pir 1, light1 on", "pir 1, light3 on", "pir 1, light2 Down"

When the second user sets a second rule at the client side to be that when the infrared sensor pir1 is triggered, the light lamps light1 and light lamps light2 are extinguished, that is:

Rule2’:{pir1, light1 Down, light2 Down}

after setting, the second control rule is sent from the client 11 to the server 12, and after receiving the second control rule set by the user from the client 11, the server 12 parses the second control rule to parse the second linkage information and its associated linkage device information

1) { (pir1, light1), light1 Down }, wherein the second linkage information is light1 Down and its associated linkages are sensor pir1 and lamp light1, indicating that lamp light1 is extinguished when sensor pir1 triggers.

2) { (pir1, light2), light2 Down }, where another second linkage information is light2 Down and its associated linkages are sensor pir1 and lamp light2, indicating that lamp light2 goes out when sensor pir1 triggers.

And calculating a hash value by performing hash calculation on the linkage equipment associated with the second linkage information, wherein the hash value is used as a second key value and corresponds to each piece of second linkage information one by one to form a deformed second control rule, and the expression is as follows:

{hash(pir1+ light1)， light1 down },{ hash(pir1+ light3)， light3 down}

the HASH is HASH calculation, and pir1+ light1 represents a combination of the name of the sensor pir1 and the name of the lamp light1, such as splicing of character strings; each hash value, i.e. the second key value, corresponds to the related second linkage information, for example, a hash (pir1+ light1) corresponds to the second linkage information light1 down, a hash (pir1+ light3) corresponds to the second linkage information light3 down, and the rest of the linkage device information is analogized. The second key value is used to search for the linkage information of the first rule in the storage module, and one method is to query the storage module by using the second key value as an address of the storage unit and extract the matching linkage information stored in the searched storage unit. After a second key value Hash (pir1+ light1) is used for finding out a matched linkage information lamp light1 for an address and is lightened ("light 1 on"), the linkage information lamp light1 is compared with linkage information lamp 1 Down "in a second control rule corresponding to the second key value, linkage information conflict of a lamp light1 in two control rules associated with pir1 is found through comparison, so that the second control rule set by a user and a first control rule set by the user are judged to conflict, the server stops setting the second control rule and sends a notification of the control rule conflict to the client 11, the notification information can comprise names and/or linkage information of associated equipment, and after the user sees a notification message of the rule conflict through the client 11, the user can timely modify the second control rule to be set. If the linkage information of the first control rule corresponding to the second key value is not found in the storage module, in this embodiment, the storage module does not have a storage unit for storing the linkage information of the lamp light3 and the sensor pir1, and the server stores the linkage information of the lamp light3 and the sensor pir1 of the second control rule as the linkage information of the new first control rule in the storage unit with the second key value as an address.

The first control rule set by the user at the client can also be issued to the gateway device in the control system, so that the gateway can control the execution device according to the trigger signal of the sensor, the linkage between the execution device and the sensor can be performed not through the server but through the local gateway, and the response speed and time are improved.
