These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present invention. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
The present invention will be described in detail below by way of examples.
The intelligent fire hydrant control system comprises a server, an intelligent fire hydrant and a positioning device, wherein the positioning device is carried by a fireman and is used for positioning the specific position of the fireman in a fire scene. The server also stores the position information of each intelligent fire hydrant.
An intelligent fire hydrant control method, as shown in fig. 1, includes the steps of:
s1: and the server determines the fire hydrant to be selected according to the current position of the fireman and the prestored position information of the fire hydrant.
Specifically, as shown in fig. 2, the S1 includes:
s101: and the server receives the positioning information sent by the positioning device and determines the current position of the firefighter.
The positioning device can adopt a GPS or a Beidou satellite navigation system to send the current position of the fireman to the server in a wireless communication mode.

L'＝L*p*ln(N)
and re-determining the preset distance, wherein L' is the re-determined preset distance, L is the previous preset distance, p is a preset percentage value, and the value of p is generally 110-120%.
The larger the number N of times of executing step S123 is, the fewer fire hydrants around the current position of the firefighter are, or even none of the fire hydrants is, so that when the preset distance is determined next time, the increment of the preset distance should be increased, and as the value N is increased, the increase of the L is increased, so that the fire hydrant to be selected can be determined as soon as possible.
S2: and the server activates the fire hydrant to be selected and receives the water pressure information of the fire hydrant to be selected.
Specifically, as shown in fig. 4, the S2 includes:
s21: and the server sends an information acquisition activation instruction to each fire hydrant to be selected.
When the intelligent fire hydrant control system is designed, the server and the fire hydrant to be selected can both carry out information communication, but under the complex environment of a fire scene, the situation that communication equipment on the fire hydrant to be selected is damaged and the like can occur, so that the fire hydrant to be selected cannot be communicated with the server. However, the wireless communication device on the intelligent fire hydrant is not in excessive contact with the fire extinguishing waterway structure and the valve body structure of the intelligent fire hydrant, and the fact that the fire hydrant cannot communicate with the server does not mean that the fire hydrant cannot be used for extinguishing fire.
Generally, fire hydrants capable of communicating with the server are more likely to be selected for use at a fire extinguishing site because the fire hydrants capable of communicating with the server can transmit real-time status information such as water pressure information of themselves to the server, so that the server can monitor the use status of the fire hydrants in real time, and the server can provide further fire hydrant status guidance for firefighters.
S22: and feeding back activated information to the server by the fire hydrant to be selected, wherein the activated information comprises the identification code of the fire hydrant to be selected.
As described above, in practice, not all the fire hydrants to be selected may be in wireless communication connection with the server, so that activated information may be fed back to the server, but at this time, the fire hydrants to be selected that are still in wireless communication connection with the server may be fed back to the server after receiving an information acquisition activation instruction sent by the server, and the server determines whether a corresponding fire hydrant is a feedback-free fire hydrant according to whether activated information fed back by the fire hydrant to be selected is received.
S23: and reading the current water pressure information of the fire hydrant to be selected.
S24: and the fire hydrant to be selected sends water pressure information to the server.
The water pressure information comprises a fire hydrant water pressure value detected by a water pressure sensor arranged on the fire hydrant to be selected.
S3: the server allocates a counter for each fire hydrant to be selected.
Specifically, the server allocates a counter for the to-be-selected fire hydrant corresponding to the identification code, and the server may allocate a computing unit having a counting function to the fire hydrant corresponding to the identification code in the internal storage space. And allocating a storage unit for storing the water pressure information sent by the fire hydrant to the fire hydrant corresponding to the identification code.
S4: the server judges whether the received water pressure information sent by each fire hydrant to be selected is consistent with preset standard water pressure information or not, if so, S9 is executed, and if not, S5 is executed.
Specifically, the S4 includes:
s41: and the server receives the fire hydrant identification codes sent by each fire hydrant to be selected.
S42: reading standard water pressure information stored in a memory corresponding to the fire hydrant identification code as front water pressure information; and the server reads the water pressure information sent by the fire hydrant corresponding to the fire hydrant identification code as the back water pressure information.
S43: the server compares whether the change rate of the water pressure information data in the front water pressure information and the rear water pressure information is greater than a preset change rate threshold value, if so, determines that the water pressure information data is consistent with preset standard water pressure information, otherwise, determines that the water pressure information data is inconsistent with preset standard water pressure information, and then executes S5.
When the change rate of the water pressure information data is more than 20%, the water pressure information is considered to be inconsistent.
S5: and determining the alarm level according to the degree and the duration of the water pressure value of the selected fire hydrant lower than the standard water pressure threshold value.
Specifically, the following formula can be used: and determining the alarm grade strength according to the alarm grade strength, wherein the alarm grade strength is duration x ln (| fire hydrant water pressure value-standard water pressure threshold |), and determining the alarm grade difference according to the alarm grade strength difference.
Specifically, according to the calculated alarm level intensity value, the server may query the alarm level corresponding to the current alarm level intensity in an "alarm level intensity-alarm level" comparison table prestored in the memory, where the alarm levels are classified into a primary alarm, a middle alarm and a high alarm.
S6: the server controls the booster pump to boost the pressure of the fire hydrant to be selected.
Specifically, the S6 includes:
s61: the server receives the water pressure information sent by the corresponding fire hydrant for multiple times.
S62: the server judges whether the proportion of the number of times that the water pressure value is smaller than the water pressure threshold value to the total monitoring number of times exceeds a first proportion value, if so, the booster pump is started, and then S63 is executed, and if not, S8 is executed.
S63: the server determines the incremental strength for starting the booster pump according to the alarm level.
Specifically, the booster pump incremental strength corresponding to the current alarm level can be found through a comparison table of the alarm level and the booster pump incremental strength prestored in the internal memory of the server. The incremental strength of the booster pump means the strength increased when the booster pump is started compared with the strength increased when the booster pump is boosted last time.
Generally, when the booster pump is opened for the needs to judge for the first time, the water pressure of fire hydrant is less, needs to strengthen the opening intensity of booster pump with great dynamics, makes the play water pressure grow of fire hydrant along with the enhancement of booster pump once, and the warning rank that corresponds the fire hydrant also descends gradually for booster pump incremental strength diminishes gradually, plays the hydraulic effect of fine setting fire hydrant.
S7: and the server controls a counter corresponding to the fire hydrant to add 1, judges whether the current count value of the counter exceeds a preset count threshold value, if so, executes S4, and otherwise, executes S8.
If the current count value of the counter of a certain selected fire hydrant exceeds the preset count threshold value, the fire hydrant still does not meet the water pressure standard of the fire hydrant under the condition that the booster pump is pressurized for multiple times, so that under the emergency fire extinguishing environment, because the time is urgent, the pressurization and judgment are not needed to be carried out any more, and the fire hydrant is directly judged to be an unavailable fire hydrant.
S8: and judging the current fire hydrant to be selected as the unavailable fire hydrant.
S9: and judging that the corresponding fire hydrant to be selected is a non-abnormal fire hydrant.
S10: the preferred strengths of the non-abnormal fire hydrant and the non-feedback fire hydrant are calculated, and the fire hydrant with the highest preferred strength is determined.
As described above, when the intelligent fire hydrant control system is designed, the server and the to-be-selected fire hydrant should both be capable of performing information communication, but in a complex environment of a fire scene, the to-be-selected fire hydrant cannot communicate with the server due to the fact that communication equipment on the to-be-selected fire hydrant is damaged. However, the wireless communication device on the intelligent fire hydrant is not in excessive contact with the fire extinguishing waterway structure and the valve body structure of the intelligent fire hydrant, and the fact that the fire hydrant cannot communicate with the server does not mean that the fire hydrant cannot be used for extinguishing fire.
Generally, fire hydrants capable of communicating with the server are more likely to be selected for use at a fire extinguishing site because the fire hydrants capable of communicating with the server can transmit real-time status information such as water pressure information of themselves to the server, so that the server can monitor the use status of the fire hydrants in real time, and the server can provide further fire hydrant status guidance for firefighters.
However, if the non-abnormal fire hydrant is obtained by pressurizing the booster pump for multiple times and the number of times of pressurization is too large, the situation that the water pressure of the fire hydrant before pressurization is not ideal is proved, and the situation that the water pressure problem of the fire hydrant occurs again in the process of using the fire hydrant is not eliminated; there is also a feedback-free fire hydrant which has a good hydraulic pressure condition in the history of the server, but cannot communicate with the server in the current situation.
Therefore, whether to select a non-abnormal fire hydrant with a possibility of water pressure problem or a fire hydrant with a good historical water pressure condition and only a possibility of disconnecting the communication system from the server is a problem to be solved.
Specifically, the selection can be made according to the following method:
in all the non-feedback fire hydrant, according to the formula
Determining a preferred strength of a feedback-free fire hydrant, wherein QIs free ofThe preferred strength of the non-feedback fire hydrant is shown, m represents the rating score of the non-feedback fire hydrant obtained according to the historical water pressure condition, wherein the value of m is 0, 1, 2 and 3, namely the non-feedback fire hydrant is divided into 'excellent', 'good' and 'medium' according to the historical water pressure condition of the non-feedback fire hydrant "The four ratings of "poor" are respectively corresponding to rating scores m of 3, 2, 1 and 0, and the rating according to the historical water pressure condition of the feedback-free fire hydrant can be determined according to different actual attention points, which is not described herein.
For each non-abnormal fire hydrant, the server counts the accumulated count value M of the counter of each non-abnormal fire hydrant; according to the formula
Determining a preferred strength of a non-anomalous fire hydrant, wherein QIs notIndicating the preferred strength of the non-anomalous fire hydrant.
S11: the server determines the fire hydrant with the highest preferred strength as the selected fire hydrant and transmits navigation information of the selected fire hydrant to the firefighter.
